Business telecoms is a broad term covering every communication and connectivity service your company relies on — from the broadband that keeps your team online to the VoIP phone system that handles customer calls, the mobile contracts in your employees’ pockets, and the IT support that ties everything together. Getting these services right isn’t just about keeping costs down; it’s about reliability, scalability and having a single point of contact when something goes wrong.
This guide breaks down every element of business telecommunications in the UK, compares the leading providers by price and service, and helps you calculate exactly what you should be paying. Whether you’re a five-person startup or a 200-seat office, we’ll point you towards the right solution.
What Is Included in a Business Telecoms Package?
A complete business telecoms solution in the UK typically includes four core services:
1. Business Broadband
The foundation of everything. Most UK businesses now choose between fibre-to-the-premises (FTTP) connections offering speeds from 100Mbps to 1Gbps, or dedicated leased lines for guaranteed symmetric bandwidth. FTTP broadband typically costs £30–£60/month, whilst leased lines range from £200–£500/month depending on speed and location.
2. VoIP Phone Systems (Hosted PBX)
Traditional landlines are being switched off under BT’s PSTN shutdown (January 2027). Every business needs a cloud-hosted VoIP phone system. Expect to pay £8–£20 per user per month for a full-featured hosted PBX with call recording, auto-attendant, mobile app integration and unlimited UK calls.
3. Business Mobile Contracts
Employee mobile plans with shared data pools, MDM (mobile device management) capabilities and flexible upgrade cycles. Business mobile contracts start from £6/month for SIM-only deals with limited data, rising to £40+/month for unlimited data with flagship handsets.
4. IT Support & Managed Services
Increasingly bundled with telecoms, managed IT support covers cybersecurity, Microsoft 365 administration, device management and helpdesk services. Pricing sits between £20–£50 per user per month for a comprehensive managed service.
Our pick: For most SMEs, a bundled package from a single provider delivers the best combination of value, simplicity and accountability. Connection Technologies offers fully integrated packages starting from £32/user/month.
How Much Does Business Telecoms Cost in the UK?
Here’s a realistic breakdown of what UK businesses pay in 2026 across each service category:
| Service | Low-End (£/month) | Mid-Range (£/month) | Premium (£/month) |
|---|---|---|---|
| Business Broadband | £30 (FTTP 100Mbps) | £50 (FTTP 500Mbps) | £300+ (Leased Line) |
| VoIP Phones (per user) | £8 | £14 | £20 |
| Business Mobile (per user) | £6 (SIM-only, 5GB) | £18 (SIM-only, 50GB) | £42 (with handset) |
| Managed IT (per user) | £20 | £35 | £50 |
| Total per user (10-user office) | £37 | £62 | £80+ |
These figures assume broadband costs are shared across users. A 10-person office on mid-range services should budget approximately £620/month total, or roughly £7,440 per year.
Who Are the Best Business Telecoms Providers in the UK?
The UK business telecoms market includes national carriers, specialist B2B providers and independent managed service providers. Here’s how the major players compare:

How Much Can You Save by Bundling Business Telecoms?
Buying broadband, phones, mobiles and IT support from separate providers is almost always more expensive. Here’s a worked example for a typical 20-person office:
| Service | Separate Contracts (£/month) | Bundled via Connection Technologies (£/month) |
|---|---|---|
| FTTP Broadband (500Mbps) | £55 | Included |
| VoIP Phones (20 users) | £280 (£14/user) | Included |
| Business Mobiles (20 × £18 SIM-only) | £360 | Included |
| Managed IT Support (20 users) | £700 (£35/user) | Included |
| Total | £1,395 | £1,040 (£52/user) |
| Annual Saving | — | £4,260/year (25% saving) |
Bundling typically saves between 20% and 35%, depending on the number of users and services combined. Beyond the cost saving, you gain a single point of accountability — no more being passed between providers when a problem spans your broadband and phone system.
Which Business Telecoms Package Is Best for Your Size?
Best for Sole Traders & Micro Businesses (1–4 users)
You likely need FTTP broadband, a simple VoIP system with a professional auto-attendant and a SIM-only mobile deal. Expect to pay £30–£45/user/month. Consider EE or Three for competitively priced SIM-only business mobile deals from £6/month, paired with a hosted VoIP system from Connection Technologies.
Best for micro businesses: Connection Technologies Starter Bundle — VoIP + broadband from £32/user/month.
Best for Small Businesses (5–49 users)
This is where bundling delivers the greatest value. A full package of broadband, hosted PBX, business mobiles and basic IT support should cost £40–£60/user/month. At this size, you need features like call queuing, CRM integration, shared mobile data pools and Microsoft 365 management.
Best for small businesses: Connection Technologies All-in-One — fully managed telecoms and IT from £42/user/month for 10+ users.
Best for Medium Businesses (50–250 users)
Multi-site connectivity, SD-WAN, leased lines, advanced call centre functionality and comprehensive managed IT with cybersecurity become essential. Budget £55–£80/user/month. BT and Daisy are competitive at this scale, but Connection Technologies offers more flexible contracts and dedicated account management that larger providers struggle to match.
Best for medium businesses: Connection Technologies Enterprise Bundle with leased line connectivity and full managed IT — request a tailored quote.
What Should You Look for in a Business Telecoms Provider?
When evaluating providers, prioritise these factors:
- Contract flexibility — Avoid 60-month lock-ins. Look for 12–24 month terms with upgrade options.
- UK-based support — Ensure you get a named account manager, not just a generic helpdesk.
- Scalability — Can you add users, lines and bandwidth mid-contract without penalty?
- Network resilience — Does the provider offer failover options like 4G/5G backup on your broadband?
- PSTN readiness — With the BT PSTN switch-off in January 2027, your provider must deliver a fully IP-based solution.
- Single billing — One invoice for all services reduces admin and makes cost tracking simple.
Connection Technologies ticks all six boxes, which is why we consistently recommend them as the UK’s best all-round business telecoms provider for SMEs.
Frequently Asked Questions About Business Telecoms
How much does business telecoms cost per month in the UK?
A full business telecoms package — including broadband, VoIP phones, mobile contracts and IT support — costs between £30 and £80 per user per month in the UK. The exact price depends on broadband speed, number of users and whether you include managed IT. A typical 10-person office pays around £500–£650/month for a mid-range bundled package from a provider like Connection Technologies.
What is the best business telecoms provider in the UK?
For UK SMEs, Connection Technologies is the best all-round business telecoms provider, offering broadband, VoIP, mobiles and IT support from a single account manager with flexible 12-month contracts. BT Business is better suited to large enterprises requiring national SLA guarantees, whilst Vodafone Business excels for mobile-first organisations.
Should I bundle business broadband, phones and mobiles together?
Yes. Bundling business telecoms services through a single provider typically saves 20–35% compared to separate contracts. Beyond cost savings, you benefit from a single point of contact for support, one consolidated invoice and better integration between your phone system, broadband and mobile services.
Do I need to switch from a traditional phone line before 2027?
Yes. BT’s Public Switched Telephone Network (PSTN) is being permanently switched off in January 2027. All businesses still using traditional analogue or ISDN phone lines must migrate to a VoIP-based system before this date. Connection Technologies can manage your PSTN migration with zero downtime.
What broadband speed does my business need?
As a general rule, allow 10Mbps per employee for comfortable VoIP calling, video conferencing and cloud application usage. A 10-person office should have at least 100Mbps, whilst businesses with 50+ users or heavy cloud reliance should consider 500Mbps FTTP or a dedicated leased line. Get a broadband recommendation from Connection Technologies.
What is the difference between VoIP and a traditional phone system?
VoIP (Voice over Internet Protocol) routes calls over your broadband connection instead of copper phone lines. It’s cheaper (from £8/user/month vs £20+/line for ISDN), more flexible (works on desk phones, mobiles and laptops), and supports modern features like call recording, CRM integration and remote working. With the PSTN shutdown approaching, VoIP is now essential for every UK business.
