Business broadband comparison
Best business broadband providers in the UK
A practical shortlist for sole traders, small offices and growing companies, based on real price, satisfaction and speed data rather than headline claims alone.

The quick answer
Vodafone Business currently has the most competitive entry-level full-fibre price, from around £20-22 a month excluding VAT. Zen Business leads on customer satisfaction, holding Which? Recommended Provider status since 2021 with 84% satisfaction and static IP included as standard. Virgin Media Business delivers the fastest raw speeds, averaging 442 Mbps, but only within its cable footprint, roughly half of UK premises. Sky Business has a consistently strong Ofcom complaints record. A leased line becomes worth its higher cost once an hour of downtime has a real, measurable cost to the business.

What makes business broadband different?
Business packages can add a static IP address, prioritised business support, security controls and a clearer fault-response commitment than a residential contract. Those specific features justify the higher price, not the word "business" on its own. A basic business FTTP service can still share network capacity with other users at peak times in the same way a residential line does; a leased line is a genuinely different, dedicated product with guaranteed, symmetric bandwidth and a formal service-level agreement.
- Static IP for VPNs, remote access, allow-lists, CCTV or hosted services
- A stated repair target and a real escalation path if it is missed
- 4G or 5G backup using a genuinely independent connection, not the same line rerouted
- Guaranteed upload capacity for cloud storage, VoIP calls and off-site backups
Business broadband or a leased line?
Standard business broadband is a contended connection: bandwidth is shared with other users nearby, so actual speed can vary at busy times, the same way a residential line does. A leased line is uncontended, delivering guaranteed bandwidth, identical upload and download capacity, and a premium contractual SLA, typically a 4 to 6-hour fix commitment.
Leased lines start from around £69 a month for a 100 Mbps entry-level connection, rising well beyond £1,000 a month for higher-capacity or enterprise-grade circuits depending on location, contract length and installation complexity. Choose one when an hour of downtime has a measurable cost to the business, when upload demand is sustained rather than occasional, or when a contractual, credit-backed uptime commitment genuinely matters, not just a marketing claim of it.
A real cost of staying on the wrong contract
Independent analysis of UK business broadband pricing found that customers who stay on an expired, out-of-contract deal pay around 24.86% more per month on average than a new-customer price for a comparable service. Reviewing the contract renewal date and re-shopping the market, rather than letting it roll over automatically, is one of the most reliably valuable actions a small business can take on this cost line.
How we would choose for an SME
Write down the realistic operational cost of one hour offline, the number of simultaneous users, and which specific applications must stay available. Then compare the total contract cost including VAT, installation, router, backup connectivity and static IP charges side by side, since providers differ meaningfully on which of these are bundled versus charged separately. Never accept an "up to" speed figure as a substitute for a stated minimum or a service-level commitment in writing.

Compare broadband optionsFrequently asked questions
Which business broadband provider is cheapest?
Vodafone Business currently offers the most competitive entry-level full-fibre price, from around £20 to £22 a month excluding VAT on a 36-month term. Confirm the VAT-inclusive total and whether a scheduled annual price increase is built into that headline figure before comparing it against a shorter-term deal elsewhere.
Which business broadband provider has the best customer satisfaction?
Zen Business has held Which? Recommended Provider status since 2021, with an 84% customer satisfaction score in independent surveys, and includes a static IP address as standard rather than as a paid extra.
Is business broadband worth it for a sole trader?
It can be, specifically if a static IP, faster fault response, or dedicated business support have real practical value for how you work. If none of those apply, a residential service with a separate mobile backup connection is often the more economical choice.
Does business broadband guarantee uptime?
Not automatically, and standard business broadband remains a contended connection shared with other users. Read the actual SLA, repair target and service-credit terms rather than assuming the word "business" implies a guarantee; only a leased line delivers genuinely uncontended, guaranteed bandwidth.
Do business broadband prices include VAT?
Often not. Most business providers advertise prices excluding VAT, so the real monthly cost is around 20% higher than the headline figure. Always compare the VAT-inclusive total, setup charges and any scheduled price rise before ordering.
How much does a business leased line cost?
Entry-level leased lines start from around £69 a month for 100 Mbps, rising well beyond £1,000 a month for higher-capacity or enterprise-grade circuits, depending on location, contract length and installation complexity. A leased line delivers guaranteed, uncontended, symmetric bandwidth and a formal SLA, unlike standard shared business broadband.
