How Much Does a Leased Line Cost? UK Price Guide 2025
UK leased line costs range from around £199 to over £1,000 per month depending on speed, location, and contract length. This guide explains what drives the price, what typical figures look like for 100Mbps to 1Gbps circuits, and how to get an accurate quote for your site.

What Is a Leased Line?
A leased line is a dedicated, uncontended fibre connection running directly to your business premises. Unlike standard broadband, the bandwidth is not shared with other users — your 100Mbps or 1Gbps circuit is yours alone, available consistently 24 hours a day. Leased lines also deliver symmetrical speeds: upload and download are equal, which matters for businesses running VoIP, video conferencing, cloud backup, and hosted servers simultaneously.
UK Leased Line Pricing in 2025
Leased line pricing in the UK has fallen consistently over the past decade as full-fibre infrastructure has expanded. The following ranges reflect current realistic market pricing for a 36-month contract:
100Mbps Leased Line
- City centre and well-connected areas: from £199–£350/month
- Suburban and edge-of-town: from £300–£500/month
- Rural and remote: from £450–£700+/month
500Mbps Leased Line
- City centre: from £350–£500/month
- Suburban: from £450–£650/month
- Rural: from £600–£900+/month
1Gbps Leased Line
- City centre: from £450–£700/month
- Suburban: from £600–£900/month
- Rural: from £750–£1,200+/month
These figures represent the monthly rental cost. Installation charges vary: many providers waive installation for standard contract terms, but sites requiring significant civil works may face charges of £500–£3,000+ depending on the extent of the build required to reach the premises.
What Drives the Cost of a Leased Line?
Location
Location is the single biggest pricing variable. A business in central Manchester or Birmingham can often get a 100Mbps leased line for under £250/month because multiple providers have active fibre infrastructure in the area, creating genuine competition. The same business in a rural village may face costs two or three times higher simply because the nearest fibre infrastructure is farther away and fewer providers have networks in the area.
Speed
Higher speeds cost more, but the price-per-Mbps decreases as you move up the speed tiers. A 1Gbps circuit is typically not ten times the cost of a 100Mbps circuit at the same location — it is closer to two to three times the cost. This means upgrading from 100Mbps to 500Mbps or 1Gbps is often better value per megabit than it appears.
Contract Length
Standard contracts are 36 or 60 months. A 60-month term typically reduces monthly cost by 10–20% compared to a 36-month term. However, a longer commitment requires confidence that the premises and the bandwidth requirement will remain stable.
Provider and Network
Multiple providers serve the same postcode in many urban areas, running circuits over different physical networks (Openreach, CityFibre, Virgin Media Business, Zayo, and others). Where genuine choice exists, competitive pricing is available. Where a single provider has a monopoly at a specific location, the price reflects that.
SLA Tier
Higher SLA tiers — faster fault response, lower MTTR, greater uptime guarantees — carry a premium. Standard leased lines offer 99.9% uptime and an MTTR of 5–20 hours. Enhanced SLA packages offering 99.95% uptime and 4-hour fix guarantees cost more but are appropriate for sites where downtime carries significant financial consequences.
Installation Lead Times
Standard leased line installation takes 45–90 working days from order. This timeline covers the site survey, wayleave processes (if applicable), civil works, and network provisioning. Sites close to existing fibre infrastructure may complete faster; sites requiring significant new duct runs take longer. Plan well in advance if you are currently on contract with another provider and need the new circuit live before your existing contract expires.
How to Get an Accurate Quote
The only reliable way to get an accurate leased line price is a postcode-level availability check combined with a site survey. Prices quoted before a survey are estimates; the firm price comes after the survey confirms the distance and nature of any civil works required.
AMVIA runs availability checks across multiple UK providers simultaneously, compares the results, and manages the quoting and survey process on your behalf. This approach identifies which networks can realistically serve your site and removes the risk of receiving an artificially low estimate that increases after the survey.
What Would a Leased Line Cost at Your Address?
Enter your postcode and AMVIA will run availability checks across Openreach, CityFibre, Virgin Media Business and more — giving you accurate pricing from the networks that can genuinely serve your site.
Frequently Asked Questions
Pre-survey estimates are based on proximity to known infrastructure. The site survey confirms the exact distance and route required to reach your building. If civil works are needed — new ducting, road crossings, wayleave agreements — the true cost is not known until these are assessed. Always ask for a post-survey firm price before signing a contract.
Yes. In competitive markets where multiple providers can serve your site, there is room to negotiate — either on price or on installation cost waivers. Providing competing quotes to a preferred provider often yields an improved offer. In single-provider areas, negotiation has less leverage. <strong>100 Mbps leased line</strong>: £240–£320/month (36-month term) in urban areas; up to £390/month in semi-rural areas. <em>(AMVIA)</em>
Yes. Leased lines include at least one static IP address as standard. A subnet of additional IPs can be purchased if your business needs to host services or manage IP-based access controls.
Most leased line providers require a minimum 36-month contract. Some offer 12-month terms at a significant premium. If you need shorter commitments, this should be explicitly negotiated before signing, as most standard terms default to 36 months.
A leased line is worth the cost over FTTP when your business requires a guaranteed minimum speed, a formal SLA for fault response, or symmetrical upload/download speeds. For teams of fewer than 20 users running standard cloud applications, FTTP broadband is usually sufficient. Above that threshold, or where downtime has serious financial consequences, a leased line is the appropriate solution. <strong>500 Mbps leased line</strong>: £411–£673/month (36-month term) — only ~58% more expensive than 100 Mbps despite 5× the speed. <em>(AMVIA)</em>
