UK Leased Line Pricing Map 2026

What this pricing map shows

There is no single "UK leased line price". A leased line is a dedicated, uncontended fibre circuit built to your specific building, so the figure you pay is shaped by your postcode as much as by the speed you order. This page fixes the two things you can actually pin down: the entry price for each speed tier in a well-served area, and the reasons that price moves once you quote a real address.

The four national floors, confirmed July 2026:

• 100 Mbps — from £69/month. The entry point for a 25–50 person office that has outgrown contended broadband.
• 1 Gbps — from £129/month. Ten times the capacity of 100 Mbps for less than twice the price. For most growing SMEs this is the tier that makes sense.
• 10 Gbps — from £349/month. Data-intensive operations, media, and sites aggregating traffic for several offices.
• 100 Gbps — from £1,999/month. A specialist tier for data centres, high-performance computing and hyperscale workloads, not a typical office purchase.

These are floors — the best case in a postcode where fibre already reaches the building. Check the live figure for your address with our leased line quote tool, or read the tier-by-tier breakdowns for 100 Mbps, 1 Gbps and 10 Gbps.

Methodology and data vintage

Transparency is the point of a pricing asset, so here is exactly what these numbers are and are not.

• Source: AMVIA's confirmed commercial floor for each speed tier, verified with our commercial team on 8 July 2026. AMVIA is network-agnostic and quotes across BT Openreach, Virgin Media Business, CityFibre, Zayo and Hyperoptic, so the floor reflects the most competitive carrier for a well-served postcode rather than a single network's list price.
• What "from" means: the monthly rental for a symmetric, uncontended circuit at the stated speed, in a commercial postcode where fibre is already present, on a standard 36-month term. It excludes any one-off install or construction charge (covered below).
• What it excludes: VAT, managed-router and SD-WAN options, and Excess Construction Charges where fibre has to be built to the premises.
• Data vintage: July 2026. Circuit pricing moves with carrier tariffs and network build, so we re-verify these floors quarterly; the next review is due October 2026.

We deliberately do not publish invented per-city price tables. Because a leased line is quoted per address, a headline "leased line price in Manchester" figure would be misleading — the number for two buildings on the same street can differ. What genuinely varies by location is explained next.

Why leased line prices vary by location

Four factors move a quote away from the floor. Understanding them tells you whether a price you've been given is fair — and where there's room to push.

• Network footprint. Where BT Openreach, CityFibre, Virgin Media Business and regional altnets all serve a postcode, carriers compete and prices fall toward the floor. Where only one network reaches the building, there is no competitive tension and you pay more. Dense urban centres — London, Manchester, Birmingham, Leeds, Sheffield — are typically well served; business parks on the edge of town often are not.
• Excess Construction Charges (ECCs). If no fibre reaches your building, the carrier has to physically build it — trenching, ducting and blowing fibre from the nearest access point. That civil-engineering cost is passed on as a one-off ECC, and it is the single biggest reason two identical circuits differ in price. Where fibre is already present, ECCs are usually zero.
• Distance to the nearest Point of Presence. The further your building sits from the carrier's nearest aggregation node, the more fibre path and, sometimes, the higher the recurring rental. Rural and semi-rural sites feel this most.
• Contract term. Longer terms lower the monthly rental because the carrier amortises any build cost over more months. A 36-month term is standard; 60 months can cut the monthly figure further, and 12-month deals carry a premium.

The practical takeaway: the recurring monthly rental clusters near the tier floors in competitive areas, and the number that really swings your total cost is the one-off install/ECC. Always ask for both, separately.

The economics of scale: why 1 Gbps is the sweet spot

Leased line pricing does not scale linearly with speed, and that is the most useful thing on this page. Priced per megabit of dedicated capacity, higher tiers are dramatically cheaper:

• 100 Mbps at £69 works out at roughly 69p per Mbps.
• 1 Gbps at £129 is about 13p per Mbps — an 81% lower unit cost than 100 Mbps.
• 10 Gbps at £349 is about 3.5p per Mbps.
• 100 Gbps at £1,999 is about 2p per Mbps.

The jump from 100 Mbps to 1 Gbps gives you ten times the headroom for under twice the monthly cost. Because the install cost and SLA are effectively identical across tiers, most businesses that can justify a leased line at all are better served buying 1 Gbps and growing into it than saving a few pounds a month on 100 Mbps. Our 1 Gbps cost guide works through when that logic holds.

How to read a leased line quote

A leased line quote has two numbers, and buyers routinely focus on the wrong one. Check both:

• Monthly rental. The recurring cost. In a competitive postcode this should sit near the tier floor above. If it's well above and only one carrier serves you, that's the footprint effect, not a rip-off — but it's worth having a broker test every network.
• One-off install / ECC. Often zero where fibre is present, but potentially four or five figures where it must be built. This is where quotes diverge most, and where a survey across multiple carriers can save the most.

Also confirm the term, the SLA (typically 99.99% or 99.95% uptime with defined fault-response and repair windows), and whether managed router, firewalling or SD-WAN are included or extra.
