Best VoIP Phone Service Provider Plans for UK Businesses in 2025

With remote work on the rise and the UK’s PSTN switch-off fast approaching in 2027, small and medium-sized enterprises (SMEs) are turning to VoIP (Voice over Internet Protocol) for cost savings, reliable call quality, and better flexibility.

Our research has found that RingCentral’s Ultimate plan is the best VoIP package for UK businesses in 2025. Offering a wide range of impressive training and call management features, extensive software integrations, and robust security measures, there’s little reason why it wouldn’t suit your team.

But it’s not the only superb VoIP out there. In our roundup below, we’ve analysed the top eight VoIP provider packages to help you pick the best choice for your business.

1. RingCentral Ultimate – Best All-Round Business VoIP Provider Plan in the UK

RingCentral’s Ultimate plan emerged as our top-rated VoIP cloud phone system for UK businesses in 2025. It’s especially well-suited to medium-sized businesses, multi-channel customer service teams, and those needing scalable communications with deep integration options.

In our research and testing assessments, it scored perfect marks in five key areas, on the way to outperforming all other providers across the board. Here’s what stood out:

RingCentral Ultimate’s key highlights

RingCentral Ultimate stood out from the other VoIP packages on this page for several reasons. Let’s dive into exactly how it betters the rest.

🔌 Best-in-class software integrations

RingCentral integrates with over 400 apps, including Salesforce, Microsoft Teams, HubSpot, Slack, and Zendesk. This means your teams can access call tools directly inside your CRM or helpdesk, streamlining workflows and avoiding sometimes painfully slow (or even broken) app switching.

This level of integration is ideal for SMEs that rely on connected systems to manage customer relationships or internal communications. You’ll have seamless app integration options with other competitors, such as 8×8 Work, which supports several CRM tools and over 70 apps altogether, but the sheer volume of RingCentral’s integration options means you’re more likely to find a fit for your existing software over any other competitor.

📞 Advanced call management features

RingCentral Ultimate comes with a suite of smart call handling tools for remote teams or growing service departments to improve their calling:

• Virtual receptionist with custom greetings
• Smart call routing and queues based on teams, business hours, or caller ID
• Call screening and blocking
• Call flipping – seamlessly transfer a call between devices mid-conversation

In our testing of the RingCentral platform, these tools made it easy to direct calls to the right person, even across multiple office locations and remote teams. There were no drop-outs in call connection when switching devices, according to our tests across iPhone and Windows devices.

Since efficient call management reduces missed calls and improves customer satisfaction (key concerns for scaling businesses), these features can be essential to your team’s performance levels.

Only Dialpad Enterprise matched RingCentral on call management scoring overall, but even so, Dialpad doesn’t offer voicemail screening, which RingCentral does. Vonage Max and 8×8 Work also have similar features, but without call flipping or routing customisation.

🎓 Comprehensive training tools

If you want to analyse staff performance in real time and train staff on their calling approach accordingly, training tools can be a major benefit (primarily for customer-facing teams). RingCentral offers a complete set of those we looked for, including:

• Call recording and real-time monitoring
• Call barge and whisper features
• Performance dashboards with custom KPIs and widgets

Having live coaching and post-call insights can be essential to build consistency across your team and improve your calling service as a result. 8×8 Work and Vonage Max also offer barge/whisper functions and scored equally in training, though all far outscored bOnline, NBC, and Google Voice, which all lack real-time coaching tools entirely.

RingCentral Ultimate pricing

RingCentral Ultimate starts at £29.99 per user, per month for a single user, with discounts for larger teams:

• £24.99/user/month (2–19 users)
• £23.99/user/month (20–99 users)
• £22.99/user/month (100+ users)

Unlike 8×8 and GoTo, which use bespoke pricing, we’d argue RingCentral’s fixed rates make it easier for SMEs to budget ahead.

Is RingCentral Ultimate right for your business?

RingCentral Ultimate is ideal for medium-sized businesses that need powerful integrations, team training tools, and scalable internal comms. But it’s not a perfect fit for everyone.

✅ Best for businesses that need:

• CRM + live chat integrations: Full compatibility with Salesforce, HubSpot, Zendesk, and WhatsApp
• Training and call visibility: Coaching tools like call whisper/barge, plus real-time dashboards
• Scalable team communications: Ideal for growing hybrid or remote teams using multiple channels

2. 8×8 Work X4 – Best Business VoIP Provider Plan for Unlimited International Minutes

8×8 Work’s key highlights

8×8 Work impressed us as the best VoIP plan for unlimited international calling, and a strong contender for customer service-heavy teams with global operations. Here’s where it stood out in our testing.

🌍 Unlimited international calling

If your business places calls abroad, 8×8 Work’s global calling allowance could save serious money. It includes unlimited inbound and outbound calls to 48 countries, including the US, France, Germany, Ireland, and Australia. This is a major win for globally distributed teams, and means UK SMEs won’t have to pay extra for international add-ons.

This puts it ahead of most providers here. RingCentral, for example, caps domestic and regional minutes (while its list of countries included doesn’t include the US). Unlike bOnline and NBC, which charge extra or require upgrades, 8×8 includes international minutes as standard, too. Only GoTo Connect Phone System is a match here, offering unlimited calls to 50+ countries.

🧑‍🏫 Powerful training and coaching tools

8×8 Work is also one of the strongest VoIP platforms for supporting employee development. Features like call monitoring, whisper, and barge allow supervisors to train and coach agents in real time. There are also detailed call analytics and performance dashboards to track trends over time.

In our hands-on testing, the barge and whisper tools worked smoothly and were easy to access via the agent dashboard, even during live calls. This makes 8×8 a standout choice for call centres or service-based businesses where performance oversight is critical.

RingCentral also offers these tools to a similar level of quality, and Vonage Max comes close (it lacks the same detail in reporting options). However, bOnline, NBC, and Google Voice all lack live coaching capabilities entirely, and only support basic call recording, making them less useful for training-heavy environments.

🧠 Integrated calling, video, and chat workspace

8×8 Work provides an all-in-one dashboard for:

• Voice calls
• Video conferencing
• Team messaging
• Voicemail transcription
• Calendar integration

This makes it easier for teams to manage communication from one platform without switching tools. During testing, we easily moved between devices, used chat during meetings, and accessed voicemail transcripts within the same workspace.

RingCentral offers all of this plus WhatsApp integration, giving it a slight edge for businesses needing live chat support channels, in our view. Still, 8×8 Work betters most alternatives for UK businesses here, including Vonage Max (lacks SMS, e-fax and native video conferencing outside of its desktop app), bOnline (without voicemail transcription or calendar integration) and NBC (no SMS or transcription).

8×8 Work pricing

8×8 Work uses a bespoke pricing model, so you’ll need to contact the sales team for a quote. Based on previous quotes we’ve researched, pricing for its average 8×8 Work plan was around £35 per user, per month, depending on your business size and contract terms.

While this is more expensive than RingCentral’s fixed pricing or GoTo Connect’s entry-level £18/month plan, the unlimited international minutes and enterprise-grade tools may justify the cost for SMEs with high outbound call volumes.

Is 8×8 Work right for your business?

8×8 Work is best for global-facing teams that need unlimited international calling, strong coaching tools, and reliable call handling. But its bespoke pricing may be less appealing for budget-conscious startups.

✅ Best for businesses that need:

• Unlimited international minutes: Across 48 countries, ideal for global teams
• Hands-on training and coaching tools: Whisper/barge, call monitoring, and detailed analytics
• Strong security and compliance features: GDPR and HIPAA-ready with full 24/7 support

❌ Consider other options if you need:

3. GoTo Connect Phone System – Best Business VoIP Provider Plan for Hardware Integration

GoTo is another VoIP provider that UK businesses will be interested in – especially those who want to integrate VoIP with their current phone hardware, according to our research.

It’s also a high flyer regarding communications channels, becoming our top scorer in this category for the extent of options it provides, including SMS support, call routing, and ring groups (which help colleagues reach the right people in different offices), as well as team chat and video conferencing tools.

GoTo Connect Phone System key highlights

GoTo Connect is the best VoIP option for businesses with existing office desk phones or those needing extensive hardware compatibility. It’s also a great fit for teams that want robust communication tools at a lower cost than many rivals.

🖥️ Best for desk phone compatibility

GoTo Connect supports more hardware brands than any other provider on this list, including Yealink, Polycom, Cisco, and Grandstream.

This makes it a top choice for businesses that want to use their existing phones instead of investing in new hardware. That’s especially true if you have teams working remotely with a wide range of different phone types and brand names, or you’re switching to VoIP.

When looking at other providers, RingCentral supports a solid range of phones but doesn’t match GoTo’s breadth, and bOnline locks you into their own branded handsets on its higher tier. NBC and Google Voice both support fewer hardware integrations, so we wouldn’t recommend them for businesses with wide hardware compatibility needs.

📡 Wide range of built-in communication channels

Compared to the competition, GoTo Connect includes a wide range of communication types:

• Voice calling to over 50 countries is included by default
• Video conferencing for 250 participants
• SMS and MMS support
• Team messaging
• Ring groups and call routing
• Call transfer and forwarding

This makes it one of the most well-rounded communication platforms in our comparison, especially for teams using multiple channels across different locations.

By contrast, RingCentral and 8×8 Work offer similar communication features, but both lack SMS support in the UK.

GoTo Connect Phone System VoIP Pricing

Our time monitoring GoTo’s website has allowed us to see a pattern. GoTo regularly switches between publicly showing its pricing and showing no pricing at all.

When pricing was public, we could see that GoTo Connect’s Phone System plan was retailing for £18 per user, per month, making it one of the most affordable VoIP options in our comparison.

Either way, it seems you’ll need to contact their sales team to process a quote anyway, so you may be able to customise packages to your preferences, too.

This quote-based pricing is similar to 8×8 Work in that respect, though at least the intermittent public showing of pricing gives some indication of costs, unlike our older estimates for 8×8 Work.

Still, it would be preferable to have fixed costs detailed in the open, as with RingCentral Ultimate’s £22.99 to £29.99 per user, per month cost (depending on user numbers) or bOnline’s ultra-cheap £13.95 per user, per month pricing.

Is GoTo Connect Phone System right for your business?

GoTo Connect is a solid all-rounder for UK-based teams looking for an affordable, easy-to-deploy VoIP system that works with a variety of existing hardware and supports multiple channels of communication.

✅ Best for businesses that need:

• Wide desk phone compatibility: Supports a wider range of hardware than any other provider on this page
• SMS and team messaging: Built-in tools for internal chat, customer texts, and notifications
• International calling at an affordable price: Unlimited UK and international calls to 50+ countries at a budget-friendly £18/user price

❌ Consider other options if you need:

4. Vonage Max – Top VoIP Provider Plan for Startups

Vonage is another global VoIP provider, with data centres in the US, Singapore, Sydney, Frankfurt, and Dublin. In 2025, we think Vonage’s Max plan is the best pick for startup businesses, offering solid value for money. It has more features than the similarly cost-friendly bOnline, with HD video conferencing, call recording, and CRM integrations all included by default (unlike bOnline), and you’ll get unlimited inbound and outbound minutes, too.

Vonage Max key highlights

Vonage Max is a good fit for UK startups and small teams that want solid functionality without a high price tag. It offers strong call quality, training tools, and value, but misses the mark slightly on communication channels and integrations.

💸 Strong value for money

Vonage Max is priced at £25 per user, per month, which includes:

• Unlimited inbound and outbound UK calls
• Native video conferencing
• Several CRM integrations with tools like Salesforce and HubSpot
• A range of call management and training features

This makes it likely to be more affordable than or equal to RingCentral Ultimate (£29.99 or £24.99 per user for one or 2-19 users respectively) for smaller teams and significantly cheaper than 8×8 Work (approximately £35 per user), while still offering many of the same core features.

It also includes more advanced tools by default than bOnline, which requires paid add-ons for things like CRM integration or video conferencing.

📞 Solid call management, but some gaps

Vonage Max includes many essential call handling features:

• Call routing and queues
• Call blocking
• Voicemail screening
• Company-wide call recording
• Spam prevention (one of the few UK providers to include this)

These tools help reduce interruptions and improve routing for small teams that deal with frequent inbound calls. However, it should be noted that Vonage lacks call flipping between devices, which RingCentral and 8×8 offer, as well as SMS messaging support, which is available from Dialpad and GoTo Connect.

🎓 Great for agent training and coaching

Vonage Max scored highly for its training capabilities in our assessment of the platform, with support for:

• Call recording
• Call monitoring
• Call barge and whisper
• Post-call analytics and reporting

These tools are essential for startups or growing customer service teams that want to build consistent call handling standards early on. It’s the sole option outside of RingCentral Ultimate and 8×8 Work to offer real-time coaching tools, with the only downside on this front being that it lacks fully custom dashboards and KPIs, which RingCentral offers on its Ultimate plan.

By contrast, Dialpad only supports call recording and analytics, without whisper/barge, while bOnline, NBC, and Google Voice offer basic training tools at best.

Is Vonage Max right for your business?

Vonage Max is ideal for startups or smaller teams that want advanced call handling and coaching tools, without committing to enterprise pricing. But it’s not ideal for businesses that rely on texting or need deeper software integrations.

✅ Best for businesses that need:

• Strong agent coaching tools: Includes barge, whisper, and call monitoring
• Unlimited domestic calls and built-in video: Great for hybrid teams and remote catch-ups
• Low-cost training features: More affordable than RingCentral or 8×8 with similar capabilities

❌ Consider other options if you need:

5. Dialpad Enterprise – Best Business VoIP Provider Plan for Small Customer Service Teams

Jumping up two places in our 2025 rankings, Dialpad’s Enterprise plan impressed us as the most suitable for smaller customer service teams (that require minimal training) and businesses experiencing high call volumes. That’s because it offers excellent call management and robust support features, including unlimited call minutes, SMS support and integration with major CRM systems like Salesforce, HubSpot, and Zendesk, but without any live call coaching tools.

Dialpad Enterprise key highlights

Dialpad Enterprise is a strong fit for small customer service teams that want advanced call handling, built-in AI tools, and SMS support — but don’t need deep training features or heavy CRM integrations.

📱 SMS messaging and spam filtering

Dialpad is one of the few VoIP providers in this comparison that supports SMS and MMS messaging in the UK, allowing teams to:

• Send appointment reminders
• Text customers directly from desktop or mobile
• Handle inbound texts from clients

That’s rare according to our research, since RingCentral Ultimate, Vonage Max, NBC, Google Voice and 8×8 Work don’t support SMS in the UK. GoTo Connect Phone System is your only other option in this regard, but it’s without advanced AI filtering.

Relatedly, Dialpad Enterprise also includes automatic spam call blocking, helping reduce interruptions and screen out low-quality leads. These tools make Dialpad a good fit for SMEs that rely on phone and text as their primary communication channels.

🤖 Built-in AI for smarter support

Dialpad’s AI-powered features help teams manage high call volumes more efficiently. The system includes:

• Real-time call transcription
• Automated post-call summaries
• AI coaching prompts based on keywords

This can significantly reduce admin time and boost response quality, especially for sales teams or small support desks. RingCentral Ultimate also offers plenty of AI tools in this regard, including call summaries and transcripts, but it doesn’t offer real-time AI coaching, which is a boon for teams without the staff numbers to employ real people to coach your phone operators.

Dialpad Enterprise pricing

Dialpad Enterprise has bespoke pricing, so you’ll need to request a quote. That said, its Standard and Pro tiers are publicly priced from £12 to £28 per user, per month, and we expect the Enterprise plan to fall above that, most likely in the £30 to £50 range.

For teams that need SMS support and integrated AI, we’d say Dialpad offers solid value, especially compared to RingCentral or 8×8, where SMS isn’t available.

Is Dialpad Enterprise right for your business?

Dialpad Enterprise is best for smaller teams that want advanced call handling and built-in SMS, but don’t require full training tools or deep integrations with CRMs.

✅ Best for businesses that need:

• SMS messaging and spam filtering: One of the only UK VoIP providers to offer both
• AI-powered call support: Live transcriptions, summaries, and keyword-based coaching
• Strong call handling: Spam screening, call routing, voicemail transcription, and mobile sync

❌ Consider other options if you need:

6. bOnline Unlimited Calling & Video – Best VoIP Provider Plan for Businesses on a Strict Budget

bOnline Unlimited Calling & Video is the cheapest VoIP system plan we’ve come across for UK teams. Our research highlights its value for money above all else, with unlimited inbound and outbound calling minutes at a lower cost than other provider plans.

bOnline Unlimited Calling & Video key highlights

bOnline is a great choice for startups or small-businesses looking for a low-cost VoIP solution with essential calling features. It delivers strong value at a low price, but has clear limitations when it comes to training tools, integrations, and security.

💰 The most affordable VoIP plan we recommend

bOnline is the lowest-priced provider in our research, starting at just £13.95 per user, per month, or £15.50 if you want a desk phone included. Both plans come with:

• Unlimited UK landline and mobile calls
• HD video meetings
• Desktop and mobile apps
• Call recording (on-demand)

This extremely low cost makes it ideal for new businesses, solo founders, or small teams looking to keep overheads low.

To put that price in perspective, RingCentral Ultimate costs £29.99 per user for one user, which might be the case for a startup finding its feet, while 8×8 Work is expected to start from £35 per user. GoTo Connect is competitively priced at £18 per user, but still more expensive than bOnline’s low cost.

Although, something to consider with bOnline is the cost of any add-ons, as the above picture details. Call recording and video conferencing will cost you an extra £5 per month each, while CRM integrations will cost you £9 per month. If you need at least one of these, GoTo Connect Phone System will be the cheaper option.

☎️ Strong for basic call management

Still, in terms of calling features, bOnline has the essentials you’ll need covered. It supports:

• Custom call routing
• Call queues and ring groups
• Call forwarding and voicemail transcription

Our research tells us these features are simple to set up, with a fairly straightforward visual routing and queuing mechanisms and clearly signposted buttons for other actions. This makes bOnline a solid option for small customer-facing teams managing inbound calls.

It matches more expensive providers like Dialpad Enterprise and Vonage Max on core routing features, even if it does lack extras like voicemail screening (available from RingCentral and Vonage) and call flipping between devices (RingCentral, 8×8, and Dialpad support this).

Is bOnline right for your business?

bOnline is ideal for small businesses, sole traders, and low-staffed teams that want cheap, functional VoIP without extras. But it’s not suited to fast-growing organisations that need advanced integrations, SMS, or coaching tools.

✅ Best for businesses that need:

• Ultra-low-cost calling: Cheapest VoIP provider on this list, with unlimited UK minutes
• Quick setup and simple tools: Easy to use and deploy without IT support
• Basic internal comms: Includes HD video meetings and call routing

❌ Consider other options if you need:

7. NBC Cloud Voice Complete Mobility – Best VoIP Provider Plan for Low-Budget Businesses

NBC Cloud Voice Complete Mobility is a solid value VoIP solution ideal for small and medium-sized businesses backed by the globally recognised Cisco BroadSoft platform – in other words, businesses can be assured that they are leveraging leading cloud VoIP technology.

Starting at £24.99 per month, it provides over 40 business-grade features, including state-of-the-art handsets and app-based management, without hidden costs.

NBC Cloud Voice key highlights

NBC Cloud Voice Complete Mobility is a budget-friendly VoIP option for UK small businesses that need solid call handling without extra integrations or training tools. It’s especially useful for teams that want unlimited UK minutes and video conferencing for large groups, but can’t stretch to premium plan prices.

💸 Solid value for small budgets

Priced at £24.99 per user, per month, NBC Cloud Voice includes:

• Unlimited inbound and outbound UK calls
• 40+ business-grade features
• App-based management for desktop and mobile
• State-of-the-art handsets (included in some packages)

For startups and small teams, we’d say this plan offers a strong feature-to-cost ratio, especially when compared to RingCentral Ultimate at £29.99 per user, per month with capped minutes, and 8×8 Work, which offers more features but typically starts at approximately £36 per user with bespoke pricing.

It’s particularly compelling for new or growing businesses looking for an off-the-shelf solution without complicated setup or sales quotes.

☎️ Reliable call management for busy lines

NBC Cloud Voice scored well in call handling thanks to features like:

• Custom call routing
• Call queues and hunt groups
• Unlimited UK calls
• Easy number porting and alternative number setup

These tools make it a good option for teams managing consistent inbound volumes. While it doesn’t offer voicemail screening or nuisance call filtering like some competitors, its essentials are well covered.

For instance, bOnline, which also offers strong basic routing, but lacks hunt groups. However, the likes of Dialpad Enterprise and RingCentral Ultimate go further with features like call flipping and voicemail screening.

👥 Great for video conferencing

NBC also stands out by supporting video conferencing, making it useful for distributed teams that need:

• Group calls with 20+ participants
• Shared access from laptops, tablets, or mobile
• Meeting continuity via its mobile app

While most providers on this list offer video tools, NBC’s scalability and device flexibility help it edge out competitors like Dialpad, which limits video to 10 participants and Vonage which lacks controls like breakout rooms.

Having said that, RingCentral and Google Voice still lead in advanced video features like whiteboarding, polls, or attendance tracking, so if you snag any of these packages, we’d say they are better picks overall in this area.

Is NBC Cloud Voice right for your business?

NBC is best for budget-conscious UK businesses that want unlimited calls, reliable call routing, and easy-to-use video conferencing — but don’t need CRM integrations or training features.

✅ Best for businesses that need:

• Unlimited UK calling at a mid-range price: No caps on inbound or outbound calls
• Desk phone support included: Great for replacing or upgrading your current phones
• Large team video meetings: Reliable conferencing for 20+ users without extra software

❌ Consider other options if you need:

8. Google Voice – Best VoIP for Businesses with a Google Workspace Subscription

Google Voice, an add-on for Google Workspace, is a communication plan on the Google platform tailored for enterprises already embedded in the Google ecosystem. Because of this, we found it to be particularly well-suited to organisations needing robust internal communications, especially when remote working, as well as stringent security measures.

Google Business Plus, Google’s most advanced Workspace plan besides its custom-priced Enterprise plan, also offers essential features such as advanced collaboration tools, extensive cloud storage, and large-scale video conferencing, all of which facilitate efficient teamwork and data management.

Google Voice key highlights

Google Voice is a natural fit for UK-based businesses already using Google Workspace, offering strong internal collaboration tools, generous storage, and industry-leading security. However, it falls short for external communications, with no CRM integrations and limited call management tools.

🧑‍💻 Best for Google Workspace users

Google Voice works seamlessly with Gmail, Google Calendar, Google Meet, and Drive. It’s especially useful for:

• Booking and joining calls directly from Google Calendar
• Receiving voicemail transcriptions in Gmail
• Collaborating via Google Chat and Meet

If your team already lives in Google Workspace, we found the setup to be fast and frictionless. There’s no need for external conferencing tools or email clients, since everything is a click away as part of the Google ecosystem.

RingCentral and 8×8 both integrate with Google Calendar and Meet, but don’t offer the same level of native access. Other platforms like bOnline and NBC don’t support Google tools at all. Overall, Google Voice makes the most sense if you’re already paying for Workspace licences, as it relies on them to function.

🔐 Excellent security and compliance

Google Voice comes with the same security infrastructure as the rest of Workspace, including:

• GDPR compliance
• eDiscovery and audit logging
• Vault for data retention and legal holds
• Advanced endpoint management
• 2-step verification (MFA) by default

This extent of VoIP security makes it especially appealing to organisations in finance, healthcare, or legal sectors, or those handling sensitive customer data. Only RingCentral and 8×8 match Google on depth of compliance and access controls, with bOnline, NBC, and Vonage all falling slightly short on the level of enterprise-grade auditing tools.

💬 Built-in collaboration and video tools

With Google Voice + Workspace, your team gets:

• 5TB pooled storage per user (with Business Plus)
• HD video conferencing for up to 500 people
• Shared drives, document approvals, and chat rooms
• Automatic voicemail transcription
• Ring groups and multi-level auto attendants (on higher tiers)

This makes it a good fit for hybrid or remote teams who want an all-in-one suite for messaging, meetings, and file sharing, without managing multiple subscriptions on different software (that require integrating, too).

However, there’s no SMS support with Google Voice, unlike Dialpad or GoTo Connect. And it also lacks live chat integrations (like WhatsApp, offered by RingCentral) on its Starter plan. You’ll need to upgrade to Business Plus or Premier to unlock many features, which increases costs further, as we’ll detail shortly.

Google Voice Starter VoIP Pricing

We found Google Voice to be competitively priced at between $10 and $30 per user, per month. While it provides unlimited inbound minutes, zero outbound minutes left a hole in Google’s features armoury, compared to the competition, resulting in it receiving a fairly middling 3.5/5 score for its value for money. Still, it could be cheap depending on your requirements, as the following prices show: 

Google Voice prices are only listed in USD, but you can purchase your subscription in the UK. Correct as of April 2025.

Where it could become less affordable is if your business isn’t already using Google Workspace. A Google Workspace account is a requirement to use Google Voice, which acts as an add-on to Workspace. This varies in price between £5 and £15 per user, per month when billed yearly for its Business Plus account. And Workspace is where Google’s extensive storage capacities come into play, as we’ll detail shortly. Here’s a quick rundown of the prices:

Google Business Plus prices are listed in GBP. Correct as of April 2025.

Is Google Voice right for your business?

Google Voice is best for small to mid-sized teams already using Google Workspace, especially if you value seamless collaboration and need strong data security. It’s less suited to teams who need CRM integrations, SMS support, or advanced call handling.

✅ Best for businesses that need:

• Deep Workspace integration: Ideal for Gmail, Calendar, Meet, and Drive users
• Strong data security and compliance: Enterprise-grade controls, MFA, and Vault
• Remote collaboration: Video, chat, and shared files in one ecosystem
