Leased Line Prices in the UK: What Can Your Business Expect?

Why is there no fixed price for a leased line?

No national price list for leased lines exists in the UK. Every quote is built for one postcode, priced on how much physical infrastructure must be built or activated to reach your building. Knowing this is the starting point for reading any quote you receive.

The biggest single variable is the distance from your premises to the provider's nearest active duct or fibre point. That distance sets the civil engineering cost of connecting your site — the difference between a £250/month quote and a £650/month quote for the same 100Mbps circuit on paper. Two units on the same business park can receive materially different prices for this reason.

For the full mechanics of how a dedicated circuit is delivered and priced, our guide to what a leased line is breaks down the build process step by step, and the business leased line pillar covers the wider product range.

What do leased line prices look like by speed and location in 2025?

Prices scale with bandwidth and fall as local provider competition rises. The starting prices below are ex VAT on a standard 36-month term, with the exact figure for your site set by how much infrastructure must be built to reach it. Installation may be included on well-connected sites or charged separately (typically £500–£2,500) where significant civil works are needed.

All figures are per month, ex VAT, on a 36-month contract. The £69/month entry point applies only to dense city-centre postcodes — City of London, Canary Wharf and similar — where multiple Tier 2 carriers compete for the same building; less-connected and rural sites pay more. A dedicated internet access circuit at your specific address is the only way to confirm the exact price for your location.

How have UK leased line prices changed over the past decade?

Leased line prices have fallen substantially over the past ten years. The expansion of full-fibre networks such as CityFibre, the maturation of Openreach's FTTP footprint, and competitive Tier 2 carriers in major cities have all pushed prices down. The UK's full-fibre rollout continues to widen this competition, as tracked by Ofcom's connectivity reporting.

A decade ago, a 100Mbps leased line cost several times today's rate. The same class of circuit now starts from £69/month — a real-terms reduction of roughly 40–50% at the lower end of the market. That trend is expected to continue modestly as full-fibre coverage reaches more suburban and semi-rural areas under Project Gigabit and Openreach's network build.

Does contract length change the price?

The standard leased line contract in the UK is 36 months. A 60-month term offers savings of roughly 10–20% on the monthly rental; a 24-month term, where available, carries a 10–15% premium over the 36-month price. Month-to-month deals are rare and expensive.

Always compare total contract cost, not just the headline monthly figure:

• £300/month on a 36-month contract = £10,800 total
• £260/month on a 60-month contract = £15,600 total

The 60-month deal is cheaper per month but costs more overall. Whether the longer term makes sense depends on your confidence that the premises and bandwidth requirement will hold steady for five years. If you may outgrow the circuit, the cheaper monthly rate can become an expensive lock-in. For most growing SMEs we benchmark, a 36-month term keeps options open — and an FTTP leased line often delivers the best price-per-megabit at renewal.

What makes a leased line quote good value?

A quote represents good value when the monthly rental reflects genuine competition at your postcode, the SLA fault-response time is proportionate to how much your operation depends on the link, installation is waived or within the normal range, and the total contract cost beats alternatives with equivalent SLAs.

Use this checklist before you sign:

• The rental reflects competition among multiple providers at the postcode, not a single incumbent
• The SLA response time matches your operational dependency on the connection
• Installation is waived or within the typical band for the civil works required
• Total cost (monthly × term + installation) is lower than equivalent-SLA alternatives

AMVIA helps UK businesses test leased line quotes against live market benchmarks and presents competitive alternatives before any commitment. For firms mid-contract or at renewal, a quick comparison frequently surfaces a better deal at current market pricing. If you also run shared connectivity, our business broadband guidance explains when a leased line is — and isn't — worth the step up.
