Leased Line Pricing by Speed Tier

100Mbps leased line cost

From £69 a month on a 36-month term in well-served areas. At this tier the decision is rarely the monthly price - it's whether to take the 100Mbps service on a 1Gb bearer, which raises the monthly slightly but turns a future upgrade to 500Mbps or 1Gbps into a configuration change instead of a second installation. For most businesses buying 100Mbps today, the honest advice is: take the bigger bearer, because bandwidth demand only moves one way. With full fibre at 78% of UK premises (Ofcom Connected Nations, Q3 2025), more addresses than ever have two or more carriers on the street, and that competition is what pulls a quote toward the floor.

1Gbps leased line cost

From £129 a month - and the reason it's our most-quoted tier is that the step up from 100Mbps is small in cash terms and large in headroom. A 1Gbps symmetric, uncontended circuit comfortably carries VoIP, video, cloud backup and a full office's SaaS workload simultaneously. If your quote for 1Gbps comes back far above this floor, it's usually a one-carrier postcode - worth checking alternative routes before accepting it, which is exactly what we do across carriers.

10Gbps and beyond

From £349 a month for 10Gbps, and from £1,999 for 100Gbps. These tiers stop being about user counts and start being about workloads: large file movement, site-to-site replication, media, CAD, or aggregating branch traffic at a head office. Install lead times matter more here too - higher-bearer circuits are more likely to need carrier network build, so start the conversation before the capacity crunch, not during it.

Installation costs, honestly

UK leased line installation typically runs £500–£2,000 (2026), covering the civil works, fibre, carrier hand-off and router. The spread is almost entirely about your address: urban premises near existing fibre sit at the bottom of the range, sites needing new ducting or wayleaves at the top - and a genuinely difficult site can exceed it, which a proper survey will tell you before you commit, not after. Carriers periodically waive or subsidise install on 36-month terms; when that promotion exists on a route we quote, it shows up in your quote.

Why "from" prices are honest here

Every leased line price on this page is a floor, not an average - the best case in a well-served area on a 36-month term. We publish them anyway because the alternative, quote-form-only pricing, wastes everyone's time. Your exact figure depends on postcode, carrier routes, bearer and term; the leased line checker turns those floors into a real per-address price within 24 hours, compared across BT Openreach, CityFibre, Virgin and route-dependent carriers such as Zayo, Colt and regional networks. For the full budgeting picture - including router, resilience options and what happens at renewal - see the leased line cost guide, or compare against a cheaper alternative in leased line vs broadband.

Leased line deals: what a good one looks like

The deals worth taking are structural, not promotional: the right bearer for your growth, install included on the term you'd have chosen anyway, an SLA with defined fix times, and a price benchmarked across every carrier that reaches your postcode rather than one provider's list price. That last one is the whole game - most "expensive" leased line quotes are simply single-carrier quotes. We compare routes as standard, and customers who take connectivity alongside managed IT get the circuit, the network edge and the support under one SLA.
