🏆 Our top picks at a glance
🎯 How we assess these systems
We supply and support all five systems on this page through Broadgate Voice & Data. Our assessments are based on real-world deployments across UK businesses of all sizes — from sole traders to 200-seat contact centres. We look at call quality, hardware flexibility, admin capability, resilience, and total cost of ownership. We don't accept payments to rank a product higher.

1. GoyYap — Best overall
GoyYap is our top-rated business phone system for UK businesses in 2026. Running on a platform trusted by over 2.5 million users across the UK and Europe, it combines genuine enterprise-grade infrastructure with the simplicity and pricing that small and mid-sized businesses need. The platform scales effortlessly from a single user to 1,000 — adding users and devices takes minutes, not days.
It stands out because of what it doesn't restrict. Almost any SIP-capable handset works on day one, so businesses migrating from PSTN can keep their existing desk phones rather than replacing perfectly good hardware. GoyYap also provides WebRTC browser-based calling (no download required), plus dedicated desktop clients for Windows, Mac and Linux — covering the full range of devices your team might use. Most competing hosted VoIP systems ignore Linux entirely.
The admin backend is the full platform portal — not a stripped-down customer dashboard. You can manage call flows, auto-attendants, call queues, ring groups, recording rules and user permissions yourself without raising a support ticket. Service plans are fully template-driven, meaning you can create and assign standardised packages across your users in bulk, or customise per user where needed. For multi-site businesses or growing teams, this makes scaling genuinely straightforward.
GoyYap also integrates natively with Microsoft Teams, giving businesses the option to use Teams as the client interface while GoyYap handles the telephony infrastructure underneath — combining the collaboration tools your team already uses with a resilient, carrier-grade phone system.
✓ Strengths
- 2.5 million users — proven at scale
- Works with virtually any SIP handset
- Full admin backend available — self-manage or fully managed by your installer
- Triple carrier and data centre redundancy
- WebRTC browser calling, no app required
- Mac, Windows and Linux desktop clients
- Template-driven service plans — easy bulk management
- Full FMC — one number, desk and mobile
- Native Microsoft Teams integration
- Scales to 1,000 users without infrastructure changes
✗ Limitations
- Less well-known brand than BT or Microsoft
- Full admin access is available but not mandatory — businesses that prefer a fully managed setup can have the installer handle all configuration on their behalf
2. MyPhones — Best for analytics
MyPhones is built on the Altos cloud telephony platform and has developed into one of the stronger options for UK businesses that need genuine visibility into how their phone system is performing. Where basic hosted VoIP gives you call logs, MyPhones goes further with its Insights reporting suite — giving managers data on call volumes, wait times, agent performance and call outcomes.
This makes it particularly suited to sales teams, customer service operations, and any business where phone performance directly drives revenue. The Insights dashboards are designed to be accessible without specialist knowledge — you don't need to export data or run reports manually.
MyPhones pricing
| Option | Cost | Notes |
|---|---|---|
| Hosted VoIP seat (standalone) | £15.95/user/mo | Per-seat licence, one-off setup fee applies |
| Handset + contract bundle | £20.00 – £55.00/user/mo | Varies by device — includes handset cost spread over contract term |
✓ Strengths
- Insights reporting suite built in
- Strong for call centre and sales environments
- Flexible, reseller-grade Altos platform
- Cloud-based — no on-site hardware required
- Handset bundles available if new hardware needed
✗ Limitations
- One-off setup fee on top of monthly cost
- Handset bundles can reach £55/user/mo at the top end
- Overkill for very small teams with simple needs
3. BT Cloud Voice — Best for enterprise credibility
BT Cloud Voice is the hosted telephony offering from BT, built on their own UK network infrastructure. For businesses where procurement decisions are risk-averse — regulated industries, larger organisations, companies with IT governance requirements — the BT brand carries real weight. SLAs are enterprise-grade and support is backed by BT's UK network operations.
BT offers several hosted platform tiers, with standard business licences ranging from £10.52 to £21.00 per user per month. Total cost varies depending on the plan tier you choose, contract length, and whether you add a call plan on top. Longer contracts typically bring the per-user cost down. It's worth getting a quote for your specific user count and usage profile as pricing is not one-size-fits-all.
BT Cloud Voice is a fully featured hosted PBX — call queuing, auto-attendant, call recording, hunt groups and mobile integration are all included. It integrates with Microsoft Teams, which makes it an option for larger organisations that want Teams collaboration but need a separate, dedicated telephony layer underneath.
✓ Strengths
- BT network — proven UK infrastructure
- Enterprise SLAs and support
- Microsoft Teams integration
- Strong compliance and security credentials
- Multiple plan tiers to match business size
✗ Limitations
- £10.52–£21.00/user/mo before call plans — premium pricing
- Contract length affects per-user cost — less flexible for growing teams
- Not device agnostic
- Slower to deploy than cloud-native alternatives
4. Gamma Horizon — Best cloud PBX for mid-market
Gamma Horizon is one of the most established hosted cloud PBX platforms in the UK channel. Built and operated by Gamma — one of the UK's leading business telecoms carriers — Horizon has been deployed across tens of thousands of UK business sites with a strong track record for reliability and feature depth.
Gamma supplies a supported range of handsets — primarily Polycom, Yealink, and Cisco — and the system is optimised around those devices. Businesses should plan for new hardware if their existing phones are not on Gamma's supported list.
