Hosted VoIP Providers UK 2026: 8 Best Options Compared

📅 Updated March 2026

Hosted VoIP Providers UK 2026 – Comparison Table

Here is a side-by-side comparison of the eight leading hosted VoIP providers available in the UK right now. All prices exclude VAT.

Need a quick recommendation? For most small UK businesses (2–50 users), Connection Technologies HyperCloud offers the best combination of price, UK-based support and features. For larger or international teams, 8×8 and RingCentral are the strongest all-round hosted VoIP solutions.

Provider Mini-Reviews

8×8 – Best for International Calling

8×8 is one of the most established hosted VoIP providers in the world, with a strong UK presence and data centres in London. Their X Series platform bundles voice, video, chat and contact centre into a single subscription. The standout feature is unlimited calling to up to 48 countries, which makes 8×8 the obvious choice for businesses with international clients or remote teams abroad.

Call quality is excellent on the 8×8 network, and the admin portal gives you granular control over call flows, analytics and user permissions. On the downside, the interface can feel complex for smaller teams, and pricing at the higher tiers is steep. If you do not need international calling, you may find better value elsewhere.

Strengths: International calling, analytics, contact centre integration
Watch out for: Complexity, higher-tier pricing

RingCentral – Best All-in-One Platform

RingCentral MVP (Message, Video, Phone) is the market leader in unified communications and one of the most feature-rich hosted VoIP solutions available. The platform includes voice calling, video conferencing for up to 200 participants, team messaging and an app marketplace with 300+ integrations including Salesforce, HubSpot and Microsoft Teams.

The AI assistant (RingSense) provides call summaries, action items and sentiment analysis. RingCentral also offers strong uptime guarantees (99.999% SLA) and 24/7 support. The trade-off is price – RingCentral is not the cheapest option, and smaller businesses may find they are paying for features they do not use.

Strengths: Feature depth, integrations, reliability, AI tools
Watch out for: Cost, feature overload for small teams

Vonage – Best for CRM Integration

Vonage Business Communications is a solid hosted VoIP platform with a particular strength in CRM and API integration. If your business lives in Salesforce, HubSpot or Zoho, Vonage plugs in natively with click-to-call, automatic call logging and screen pops showing caller details before you pick up.

The platform also offers Vonage APIs for businesses that want to embed voice, SMS or video into their own applications. Pricing is competitive on the entry-level plan, though the features you actually want (CRM integration, call recording) often require the Premium or Advanced tiers. UK support has improved significantly since the Ericsson acquisition.

Strengths: CRM integration, API platform, competitive entry pricing
Watch out for: Key features locked to higher tiers

BT Cloud Voice – Best Big-Name UK Provider

BT Cloud Voice is BT’s hosted VoIP offering for small and medium businesses. It runs on the BT network, which means reliable call quality across the UK, and comes with the reassurance of a well-known British brand. Features include auto-attendant, hunt groups, call recording and a mobile app for remote working.

BT Cloud Voice is a sensible choice for businesses that already have BT broadband and want to keep everything under one roof. However, it lacks the advanced UCaaS features of platforms like RingCentral or 8×8, and the per-user pricing is higher than many independent VoIP providers in the UK. The onboarding process can also be slower than cloud-native competitors.

Strengths: BT network reliability, brand trust, bundling with BT broadband
Watch out for: Limited advanced features, higher pricing, slower setup

Connection Technologies HyperCloud – Best for UK SMEs

HyperCloud is a UK-built hosted VoIP platform from Connection Technologies, designed specifically for small and medium businesses. What sets it apart is the combination of competitive pricing (from £8/user/month), UK-based support with named account managers, and a white-glove onboarding process where the provider configures everything for you.

Features include call recording, real-time wallboards, CRM integration, auto-attendant, voicemail-to-email and a mobile app. The platform is hosted in UK data centres with full redundancy. HyperCloud does not try to be everything to everyone – it focuses on delivering a reliable, well-supported business phone system without the bloat or cost of the global UCaaS giants.

Strengths: UK support, value pricing, white-glove setup, no bloat
Watch out for: Fewer third-party integrations than RingCentral or 8×8

GoTo Connect – Best for Simplicity

GoTo Connect (formerly Jive) is a straightforward hosted VoIP platform that prioritises ease of use. The visual dial plan editor lets you drag and drop call flows without any technical knowledge, and the admin portal is one of the cleanest in the market. Video meetings for up to 250 participants are included on all plans.

GoTo Connect works well for small teams that want a reliable phone system without a steep learning curve. The mobile and desktop apps are polished, and hot desking support makes it practical for flexible workspaces. It is less suited to larger businesses that need advanced analytics, workforce management or deep CRM integration.

Strengths: Ease of use, visual dial plan, included video meetings
Watch out for: Limited analytics, fewer integrations

Dialpad – Best for AI Features

Dialpad is the most AI-forward hosted VoIP provider on this list. Every call is transcribed in real time using Dialpad’s own AI engine, and the platform provides live coaching prompts, sentiment analysis and automatic post-call summaries. If your business handles a high volume of calls and wants data-driven insights, Dialpad is compelling.

The platform integrates tightly with Google Workspace and Microsoft 365, and the interface is modern and intuitive. Pricing is mid-range, and the AI features are available on all paid plans rather than being locked behind enterprise tiers. The UK presence is growing but still smaller than 8×8 or RingCentral, so check support hours and local number availability for your area.

Strengths: AI transcription, real-time coaching, modern interface
Watch out for: Smaller UK presence, limited local number coverage

3CX – Best for Control and Flexibility

3CX takes a different approach to hosted VoIP. Rather than a fully managed cloud service, 3CX provides the software platform that you (or your IT provider) host and manage. You can run it on your own server, in a private cloud or use 3CX’s hosted option. The free tier supports up to 10 users, making it genuinely cost-effective for micro-businesses.

The platform includes voice, video, live chat and Facebook/WhatsApp messaging integration. Because it is open-platform, you choose your own SIP trunk provider, which can significantly reduce call costs. The trade-off is that 3CX requires more technical involvement than fully managed alternatives – updates, security and configuration are your responsibility unless you use a managed hosting partner.

Strengths: Free tier, open platform, low call costs, flexibility
Watch out for: Requires technical management, no included SIP trunking

How to Choose a Hosted VoIP Provider

Choosing between hosted VoIP providers comes down to matching your business requirements to the right platform. Use this checklist to narrow your options:

• Team size: Some providers are better suited to 5-person offices, others to 500-seat contact centres. Check minimum and maximum user counts.
• Feature requirements: List your must-have features (call recording, CRM integration, video conferencing, auto-attendant) and check which tiers include them.
• Budget: Compare the per-user monthly cost at the tier that includes the features you need – not just the headline entry price.
• Contract terms: Monthly rolling contracts offer flexibility. Annual contracts are typically 15–20% cheaper. Avoid contracts longer than 24 months.
• Call volumes: Check whether calls are included or charged per minute. Unlimited UK calling plans are standard, but international and mobile calls may cost extra.
• Integration needs: If you rely on Salesforce, HubSpot, Microsoft Teams or other platforms, check native integration availability.
• Support quality: UK-based support with named account managers is a significant advantage over offshore call centres. Check support hours and response time SLAs.
• Scalability: Can you add or remove users easily? What happens to pricing as you grow?
• Reliability: Look for published uptime SLAs (99.99% or better) and ask about redundancy and disaster recovery.
• Number porting: Confirm the provider can port your existing UK phone numbers and ask about the timeline.

Hosted VoIP Costs Compared

Here is what each provider typically costs for a 10-user business on their most popular plan. All prices exclude VAT and are based on annual billing where available.

These figures are indicative. Actual costs vary based on contract length, number of users and any add-ons. The most reliable way to get accurate pricing is to request tailored quotes from providers directly or through a broker.

What to Ask Before Signing with a VoIP Provider

Before committing to any hosted VoIP provider, make sure you get clear answers to these questions:

1. What is included in the per-user price? Some providers bundle calls, others charge per minute. Check what “unlimited” actually covers (UK landlines only, or mobiles too?).
2. What are the contract terms? Monthly rolling, 12-month or 24-month? What are the early termination fees?
3. Where is the platform hosted? UK-hosted data centres offer lower latency and may be required for data compliance.
4. What is the uptime SLA? Look for 99.99% or better, with financial credits if the provider fails to meet it.
5. How does number porting work? Confirm your existing numbers can be ported, the timeline and any costs involved.
6. What support is included? UK-based phone support? Email only? What are the response time guarantees?
7. What hardware do I need? Can you use existing phones, or do you need to buy new IP handsets? Are softphone apps included?
8. How are updates and maintenance handled? Fully managed providers handle everything. Self-hosted platforms like 3CX require you to manage updates.
9. What happens if I want to leave? Can you port numbers out? Is there a notice period? Are there exit fees?
10. Can I trial the system first? Most reputable VoIP providers in the UK offer a 14–30 day free trial. If they do not, ask why.

Why Use a Telecoms Broker?

With eight strong hosted VoIP providers to choose from (and dozens more beyond this list), comparing options yourself can be time-consuming. A telecoms broker simplifies the process by doing the comparison for you.

Here is how it works:

1. You tell the broker your requirements (team size, features, budget, current setup)
2. The broker compares pricing and features across multiple hosted VoIP providers
3. You receive tailored quotes with a clear recommendation
4. The broker manages the onboarding, number porting and setup

A good broker is free to use – they are paid by the provider, not by you. This means you get expert advice, competitive pricing (brokers often access trade rates below retail) and ongoing support without any additional cost.

We work with all the providers listed in this guide and can give you an honest, unbiased comparison based on your specific needs. Whether you need a cloud phone system for 5 users or a hosted VoIP solution for 500, we will find the right fit.
