For many businesses, a leased line isn’t just about speed — it’s about finding the best possible price without compromising on reliability. But with so many providers in the UK, which ones consistently come out cheapest in 2025? Let’s take a closer look.
Why “Cheapest” Isn’t Always “Best”
Before diving into the names, it’s worth remembering: the cheapest leased line on paper may not always deliver the best long-term value. Factors like uptime, SLA (service level agreements), and installation lead times all matter. That said, some providers consistently deliver lower monthly costs in the right areas.

What Affects Leased Line Prices?
Even the cheapest provider for one postcode may be expensive in another. Costs are influenced by:
-
Location: Urban vs rural coverage.
-
Bandwidth: 100Mb vs 1Gb vs 10Gb+.
-
Contract term: Free installation is often only available on 36-month deals.
-
Construction: If new digs are needed, costs can rise.
