|---|---|---|---|---|---|
| BT Business This page | Business Full Fibre 100 | From £35/mo ex-VAT | Up to 900 Mbps + leased lines | 36 to 60 months | Static IP on every plan, 24/7 UK business desk, SLA-backed fault response |

Prices verified on and exclude VAT where the provider quotes ex-VAT. BT and Vodafone run on the Openreach network, while Virgin Media Business uses its own cable, so availability and real-world speeds vary by postcode.

Beyond broadband
BT Business bundles voice, mobile and security alongside broadband, so a single account manager handles the lot and you get one consolidated invoice every month.
From £8/user/mo
Hosted VoIP phone system that replaces analogue lines and on-premise PBX. Works on desk handsets, mobile and softphone apps with one number per user.
SIM-only from £12/mo
SIM-only and handset plans for SMEs on the EE 5G network. Integrated billing with BT Business broadband and shared data pools across the team.
Bundled or add-on
Managed firewall, DDoS protection and Microsoft 365 security add-ons. Useful if you handle customer data, payments or hold ISO 27001 obligations.
Inc. on Fibre 500/900
Automatic 4G failover if your main fibre line drops. Included as standard on Business Full Fibre 500 and 900, optional on Fibre 100 for a small extra fee.
Business vs home
It is tempting to plug a residential BT broadband line into the office to save money. Here is what you lose by doing it, side by side.
| Feature | BT Business | BT Home |
|---|---|---|
| Contract length | 36 to 60 months | 24 months |
| IP address | Static IP on every plan | Dynamic IP (changes regularly) |
| Support hours | 24/7 UK-based business desk | Residential support hours |
| Fault response | SLA-backed, engineer-priority | No SLA, best-effort fix |
| Pricing display | Ex-VAT (20% added at checkout) | Inc-VAT (final price shown) |
| Account manager | Dedicated from 5 lines | No account manager |
If your business depends on the connection, the SLA and static IP are usually worth the premium on their own. The ex-VAT pricing also means a registered business can reclaim the 20% VAT, narrowing the real gap with home broadband.
FAQ
BT Business is a separate brand inside BT Group with its own contracts, support team and billing. The big differences: B2B contracts run 36 to 60 months, you get a static IP, fault response is backed by an SLA, support is on a UK-based business desk 24/7, and prices are shown ex-VAT. Consumer BT broadband is none of those things.
Halo Connect is BT Business’ premium broadband package. It bundles Full Fibre 900 with EE 4G Assure failover, a priority engineer fix on faults, dedicated business WiFi and access to BT’s Cloud Voice phone system at a discount. It is aimed at offices that cannot afford to lose connectivity during the day.
Yes. BT Business will sell to a sole trader as long as you have a registered business (Companies House or HMRC self-assessment) and a business bank account. The Business Full Fibre 100 plan at £35/month ex-VAT is the typical starting point for a one-person operation that needs a static IP and proper SLA support.
Often, yes. On headline price, Vodafone Business Full Fibre 100 starts from around £26.50/month ex-VAT and Virgin Media Business Voom tiers from £29.95/month, versus BT Business Full Fibre 100 at £35/month ex-VAT. BT’s premium buys a static IP as standard, a 24/7 UK business desk and an SLA-backed fault response, which a sole trader on light usage may not need. Compare the providers in the table above, then check our best business broadband guide before you commit to a 36-month contract.
BT Business quotes around 10 working days minimum to switch an existing line, and roughly 14 working days for a new Full Fibre installation that needs an engineer. If you rely on alarm systems or card machines, BT runs a compatibility check first, since traditional phone lines are being retired by January 2027. Read our how to switch broadband guide for the full process.
Yes. BT Business sells two leased-line products: BT Ethernet Connect (uncontended dedicated bandwidth from 100 Mbps to 10 Gbps symmetric) and BT Ethernet Flex (a flexible variant where you scale bandwidth up and down monthly). Both come with a 5-hour engineer fix SLA and start from around £200/month ex-VAT depending on location and bandwidth. See our leased lines guide to learn when a dedicated line beats shared business broadband.
BT business broadband deals lock you in for 36 to 60 months, so it pays to check the alternatives first. Compare every UK provider on speed, price, uptime SLA and static IP in one place.
