Updated April 2026 · Reviewed quarterly by Connection Technologies’ telecoms specialists
Business telecoms is the backbone of every UK company, yet most decision-makers overpay simply because they haven’t compared the market recently. Whether you’re setting up a new office, scaling your team, or reviewing contracts that are about to expire, this guide covers everything: VoIP phone systems, business broadband, mobile contracts, and managed IT services.
We’ve compiled real pricing from every major UK provider — Vodafone, BT, EE, Three, O2, and Virgin Media O2 Business — so you can make informed decisions in one place.
What Does Business Telecoms Include in 2026?
Business telecoms refers to the complete communications infrastructure a company needs to operate. In 2026, that typically includes four core services:
- Business phone systems — Almost universally cloud-hosted VoIP since the PSTN switch-off began. Includes desk phones, softphones, auto-attendants, and call recording.
- Business broadband — FTTP (full fibre), SOGEA, or leased lines depending on your speed and reliability requirements.
- Business mobile contracts — Smartphones, SIM-only deals, and mobile device management (MDM) for staff on the move.
- Managed IT & cybersecurity — Cloud services, Microsoft 365, endpoint security, and ongoing IT support.
Key point for 2026: The UK’s traditional copper phone network (PSTN/ISDN) is now in its final phase of retirement. If your business still uses analogue phone lines, you must migrate to a VoIP solution this year. Connection Technologies offers free migration assessments to help you switch without downtime.
How Much Does Business Telecoms Cost Per Employee in the UK?
The total cost depends on which services you bundle and the size of your team. Here’s what UK businesses typically pay per employee per month in 2026:
| Service | Typical Cost (per user/month) | Budget Option | Premium Option |
|---|---|---|---|
| VoIP Phone System | £8–£25 | £8 (softphone only) | £25 (desk phone + UC features) |
| Business Broadband | £4–£30* | £25/month FTTP shared | £300/month leased line |
| Mobile Contract | £10–£45 | £10 SIM-only | £45 (handset + unlimited data) |
| Managed IT / Microsoft 365 | £10–£50 | £10 (M365 licence only) | £50 (fully managed IT) |
| Total Per Employee | £32–£150 | £32 | £150 |
*Broadband cost per employee depends on team size; a £50/month FTTP line shared among 10 users is £5 per head.
Best for most small businesses (5–50 staff): A bundled package at £55–£80 per employee covering VoIP, fibre broadband, and SIM-only mobiles offers the best balance of functionality and value.
Which UK Business Mobile Provider Is Best in 2026?
Choosing a business mobile provider comes down to coverage at your locations, data allowances, and contract flexibility. Here’s how the four major UK networks compare for business contracts in April 2026:
| Provider | SIM-Only From | With Handset From | 5G Coverage | Best For |
|---|---|---|---|---|
| Vodafone Business | £12/month | £28/month | Excellent | International roaming & larger fleets |
| EE Business | £14/month | £32/month | Best in UK | Speed and coverage in rural areas |
| Three Business | £9/month | £24/month | Good (urban) | Budget-conscious teams with high data usage |
| O2 Business | £11/month | £27/month | Good | Flexible shared data plans |
Pros and Cons by Network
Vodafone Business
- ✓ Strongest international roaming packages (100+ destinations included)
- ✓ Excellent multi-line discounts for 10+ SIMs
- ✗ Online portal can be slow for account management
- ✗ Mid-range pricing — not the cheapest
EE Business
- ✓ Widest 5G coverage across the UK (now covering 60%+ of the population)
- ✓ Best for employees in semi-rural or rural locations
- ✗ Premium pricing — typically £2–£5 more per line than competitors
- ✗ Less flexible on short-term contracts
Three Business
- ✓ Lowest entry price for SIM-only deals
- ✓ Unlimited data plans genuinely uncapped
- ✗ 5G coverage still patchy outside major cities
- ✗ Customer service for business accounts inconsistent
O2 Business
- ✓ Shared/pooled data plans reduce waste across teams
- ✓ Good integration with Virgin Media for bundled office broadband
- ✗ 5G rollout slower than EE and Vodafone
- ✗ Handset range slightly smaller for enterprise
Our pick: For most UK businesses, Vodafone offers the strongest all-round package for fleets of 5+ lines, while Three is best for cost-conscious teams that primarily work in urban areas. Connection Technologies compares all four networks side-by-side and can often secure rates below those listed publicly. Compare business mobile deals here.
What Is the Best Business Broadband for UK Companies?
Business broadband in 2026 typically falls into three tiers. Your choice depends on how many employees share the connection, whether you run cloud-hosted phone systems, and how critical uptime is to your operations.
FTTP (Full Fibre) — Best for Most Small Businesses
Full fibre to the premises is now available to over 70% of UK business addresses. Prices range from £25–£60/month for speeds between 100Mbps and 900Mbps. Providers include BT Business, Vodafone, and Sky Business. This is sufficient for offices of up to 20–30 employees running VoIP, video conferencing, and cloud applications.
SOGEA Broadband — Budget Fallback
Where FTTP isn’t available, SOGEA (Single Order Generic Ethernet Access) delivers speeds of 40–80Mbps from around £20–£35/month. Adequate for very small teams but increasingly inadequate for bandwidth-heavy cloud tools.
Leased Lines — Best for Reliability-Critical Businesses
A dedicated leased line provides symmetrical speeds (equal upload and download), guaranteed bandwidth, and an SLA-backed uptime guarantee — typically 99.9%. Prices range from £200–£500/month for 100Mbps–1Gbps. Essential for businesses running contact centres, processing payments, or hosting on-site servers.
Best for small businesses (under 20 staff): FTTP at 300Mbps+ gives you headroom for growth at under £50/month. Best for medium businesses (20–100 staff): A leased line with FTTP as failover is the gold standard in 2026.
What Is the Best Business Phone System in 2026?
Following the PSTN switch-off, every UK business phone system is now VoIP-based (Voice over Internet Protocol). The question is no longer “should I switch to VoIP?” — it’s “which hosted phone system suits my business?”
Key features to compare include:
- Auto-attendant / IVR — Automated call routing (e.g., “Press 1 for sales”)
- Call recording — Now a compliance requirement in many regulated sectors
- CRM integration — Connecting your phone system to HubSpot, Salesforce, or Microsoft Dynamics
- Mobile app / softphone — Enabling staff to make and receive business calls from their mobile
- Microsoft Teams integration — Direct routing or operator connect for Teams-native calling
Popular hosted VoIP platforms in the UK include Gamma Horizon, 3CX, 8×8, and RingCentral. Pricing ranges from £8–£25 per user per month depending on features.
Our pick: For UK SMEs, Gamma Horizon — supplied and supported through Connection Technologies — offers the best combination of reliability, feature depth, and UK-based support. It integrates natively with Microsoft Teams and includes call recording, auto-attendant, and mobile twinning as standard from £12 per user per month.
Do I Need Managed IT Services as Part of My Telecoms Package?
Increasingly, yes. Business telecoms and IT are now inseparable. Your phone system runs over your broadband, your email sits in the cloud, and your security depends on endpoint management across every device — including those business mobiles.
A growing number of UK SMEs are consolidating their telecoms and IT support under a single provider. The advantages are clear:
- ✓ Single point of contact when something goes wrong
- ✓ Integrated security policies across phones, broadband, and devices
- ✓ Simpler billing — one invoice instead of four or five
- ✓ Better pricing through bundled contracts
Connection Technologies offers managed IT services alongside telecoms — covering Microsoft 365 administration, cybersecurity, cloud backup, and responsive helpdesk support from £15 per user per month.
Best for businesses without an in-house IT team: A combined telecoms + managed IT package eliminates the need to manage multiple supplier relationships and ensures nothing falls between the gaps.
How Do I Choose the Right Business Telecoms Provider?
When comparing business telecoms providers in the UK, focus on these five factors:
- Independence — Independent providers like Connection Technologies compare deals across all major networks rather than pushing a single brand. This typically saves 15–30% versus going direct.
- Contract length — Standard business contracts are 24–36 months. Beware of auto-renewal clauses; always diarise your renewal date at least 90 days in advance.
- Support quality — Ask where their support team is based and what their average response time is. UK-based support with a named account manager should be the minimum expectation.
- Scalability — Can you add or remove lines/users month-to-month, or are you locked into a fixed user count?
- Bundling savings — Combining phones, broadband, mobiles, and IT with a single provider almost always reduces cost and complexity.

What’s Changing in UK Business Telecoms in 2026?
Three major shifts are shaping the market this year:
1. The PSTN Switch-Off Enters Its Final Phase
Openreach is now actively decommissioning traditional phone lines across the UK. If you haven’t migrated to VoIP yet, treat it as urgent. Read our full PSTN switch-off guide.
2. AI-Powered Communication Tools
Business phone systems now offer AI call transcription, sentiment analysis, and automated post-call summaries as standard or add-on features. These tools are transforming how sales and support teams operate.
3. 5G as a Primary Connection
With 5G business broadband routers now widely available from EE (from £40/month) and Three (from £30/month), some smaller offices are using 5G as their primary internet connection — eliminating the need for fixed-line broadband entirely.
Frequently Asked Questions
How much does business telecoms cost per month in the UK?
Business telecoms in the UK typically costs between £30 and £150 per employee per month, depending on the services included. A standard package covering VoIP phones, fibre broadband, and SIM-only mobiles averages £55–£80 per employee for most SMEs.
What happens when the PSTN switches off?
The UK’s traditional phone network (PSTN/ISDN) is being permanently decommissioned by Openreach. All businesses must migrate to a VoIP-based phone system. If you haven’t switched, your analogue lines will stop working when your exchange is upgraded. Connection Technologies offers free migration support.
Which is the best mobile network for UK businesses?
For overall coverage and features, Vodafone Business and EE Business are the strongest choices in 2026. Three offers the best value for data-heavy, urban-based teams. The best network depends on coverage at your specific locations — Connection Technologies runs free coverage checks across all four networks before recommending a provider.
Can I bundle business phones, broadband, and mobiles with one provider?
Yes, and it’s the most cost-effective approach. Independent telecoms providers like Connection Technologies bundle services from multiple carriers into a single managed package, typically saving businesses 15–30% compared to sourcing each service separately.
What broadband speed does my business need?
As a rule of thumb, allow 10–25Mbps per employee for standard office use (email, cloud apps, VoIP). A team of 10 should aim for at least 100Mbps. Teams running video conferencing heavily or using cloud-based design tools should double that figure. Check your options by postcode.
Is Connection Technologies a telecoms provider or a broker?
Connection Technologies is an independent B2B telecoms provider that works with all major UK networks and service platforms. We act as your single point of contact for business mobiles, VoIP phone systems, broadband, leased lines, and IT services — comparing options across the market and managing everything ongoing so you don’t have to.
