Business broadband
What business
broadband costs
Priced on connection & SLA
Full-fibre & leased lines- Business broadband cost depends mostly on connection type: standard full-fibre is the affordable mainstream option; a leased line costs significantly more for guaranteed performance.
- The main price drivers are speed, the service level agreement (SLA/uptime guarantee), contract length, and any install or setup cost.
- Full-fibre suits most small and medium businesses; a leased line is a premium product for businesses that can't afford downtime.
- The only accurate figure is a quote for your postcode and needs — availability and price vary by location.
"How much does business broadband cost?" is a fair question with a range of answers, because it depends far more on what you're buying than on the provider. Here's what shapes the price and how to make sure you're paying for what you actually need.
What drives the cost
A few things set your price:
- Connection type — this is the biggest factor. Standard full-fibre (FTTP) is the affordable, mainstream choice; a leased line is a premium, dedicated connection that costs considerably more.
- Speed — faster tiers cost more, though full-fibre now offers high speeds at sensible prices.
- Service level agreement (SLA) — guaranteed uptime and fast fault-fix times cost more, and are a core reason business broadband sits above home broadband.
- Contract length and install — longer terms can lower the monthly rate; leased lines in particular can carry an install cost.
Full-fibre vs leased line
In broad terms, standard business full-fibre is the everyday, affordable option that suits the large majority of businesses. A leased line costs substantially more — it's a dedicated, uncontended connection with symmetrical speeds and a guaranteed SLA, built for businesses where downtime is simply not an option. We compare the two in our guide on FTTP vs leased line.
What most businesses actually need
For most small and medium firms, full-fibre delivers fast, reliable performance at a fraction of a leased line's cost. The honest test is our usual one: how much does an hour offline cost you? If downtime means lost sales, unanswered calls or idle staff, the SLA of a business connection earns its price — see business vs home broadband. This matters more now the old copper phone network is being switched off and phones are moving onto the internet — see the copper switch-off guide.
How to keep it fair
Match the connection to your real needs rather than the biggest package, check what's actually available at your postcode, and compare providers on price and SLA. Because availability and price vary by location, the only accurate figure is a quote for your premises.
