How much does business broadband cost?

Standard full-fibre is the affordable, mainstream option for most businesses, while a leased line costs significantly more for guaranteed, uncontended performance. Here's what drives the price and how to match it to what you actually need.

Key takeaways
  • 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:

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.

FAQ

Broadband — Common Questions

It depends mainly on connection type. Standard business full-fibre is the affordable mainstream option, while a leased line costs significantly more for guaranteed, dedicated performance. Price also varies by speed, SLA, contract length and location, so the only accurate figure is a quote for your postcode.
A leased line is a dedicated, uncontended connection used only by your business, with symmetrical speeds and a guaranteed uptime SLA. That guaranteed performance costs more than shared full-fibre, which is why leased lines suit businesses that can't afford downtime.
For the large majority of small and medium businesses, yes. Full-fibre delivers fast, reliable speeds at a fraction of a leased line's cost. A leased line is worth it mainly where any downtime seriously hurts.
Mainly the service level agreement — guaranteed uptime and fast fault-fix times — plus usually a static IP and priority support. You're paying for reliability and support, which matters more as phones move onto the internet.
