1Gbps Leased Line Costs in the UK
1Gbps leased line pricing starts from £129/month, with typical regional ranges up to £1,200+ per month depending on postcode. This guide breaks down real gigabit pricing by area, what moves the number, and how to compare carriers for your address.
Quick answer: what does a 1Gbps leased line cost?
A 1Gbps leased line costs from £129/month, with typical UK ranges of £129–£700 in London, £129–£800 in regional cities, and up to £1,200+ in semi-rural areas. The sharpest pricing comes via alt-net carriers like CityFibre and Hyperoptic where they serve the postcode. Installation is typically £500–£2,000, often waived on a 36-month term. The gigabit tier is the most popular choice for cloud-heavy UK SMEs — and often costs less over the ranges above than businesses expect.

1Gbps Leased Line Pricing by Region (2026)
Monthly pricing ranges for a 1Gbps dedicated leased line. The spread within each region reflects distance to the nearest fibre and how many carriers compete for your postcode.
| Location | Monthly Cost Range | Notes |
|---|---|---|
| LondonMost competitive | £129–£700 | Multiple gigabit carriers on most commercial postcodes |
| Regional cities (Manchester, Birmingham, Leeds, Sheffield) | £129–£800 | Alt-net coverage is expanding fast, pulling prices down |
| Suburban areas | £129–£950 | Fewer competing carriers; distance to fibre matters more |
| Semi-rural areas | £129–£1,200+ | Excess construction charges possible where fibre must be built |
What Drives the Price of a 1Gbps Leased Line
The spread between £129 and £1,200+ per month comes down to six factors — most of them about your address, not the product.
Location and distance to fibre
The dominant factor. Where an alt-net like CityFibre already passes your building, gigabit pricing starts from £129/month. Where fibre must be extended, monthly costs rise and excess construction charges of £500–£10,000+ can apply.
Carrier competition at your postcode
London and major cities have several gigabit carriers competing; semi-rural postcodes may have one. More competition means lower pricing — a multi-carrier comparison finds whoever is cheapest for your specific address.
Contract length
Most carriers require a minimum 36-month term and often waive the £500–£2,000 installation charge at that length. Shorter terms push the monthly price up.
SLA level
A 99.95%–99.99% uptime SLA with defined repair times is standard. Enhanced SLAs with faster fault-response targets typically add 10–15% to the monthly cost.
Installation complexity
Wayleaves, listed buildings and long private approaches add engineering cost. A physical site survey during the 30–90 working-day install confirms the final figure before you're committed.
Bearer and committed rate
A full 1Gbps on a 1Gbps bearer is the standard order. Some businesses instead take a 1Gbps bearer with a lower committed rate (say 200Mbps) to keep costs down now and upgrade by configuration later.
Who is a 1Gbps leased line right for?
The gigabit tier is the most popular leased line speed for UK SMEs — the sweet spot for cloud-heavy businesses, multi-team sites, and anyone whose work involves moving serious data: large file transfers, off-site backups, video production, heavy Microsoft 365 or ERP use across 50+ staff. Because a leased line is symmetric and uncontended, 1Gbps dedicated means 1Gbps upload as well as download, all day, backed by an SLA.
If your team is under ~50 staff with modest cloud use, the 100Mbps tier (from £69/month) may be plenty. If you aggregate multiple sites or run data-intensive workloads, look at 10Gbps.
Why does the same 1Gbps circuit get such different quotes?
Gigabit pricing starts from £129/month and is engineered per address: each carrier prices from where its existing fibre runs relative to your building, and the sharpest offers come from alt-nets such as CityFibre and Hyperoptic on postcodes their networks already serve. Step outside those footprints and pricing rises with distance to fibre. That's why the only meaningful gigabit price is a multi-carrier quote for your postcode — see the full UK leased line cost breakdown for how this works across every tier.
Monthly cost vs one-off costs
- Installation: typically £500–£2,000 as a one-off, frequently waived on a 36-month contract.
- Excess construction charges (ECCs): £500–£10,000+ where fibre has to be physically built to your premises — always surfaced by a proper availability check before you commit.
- Enhanced SLA: faster repair targets typically add 10–15% to the monthly cost.
- Failover: pairing the circuit with backup connectivity protects against the outages even a 99.99% SLA can't prevent.
Is the jump from 100Mbps worth it?
Often, yes — and by less margin than expected. In well-served urban postcodes the gap between 100Mbps (from £69/month) and 1Gbps (from £129/month) can be under £100/month for ten times the capacity. If your headcount is growing or your workloads are getting heavier, buying the gigabit tier now avoids paying for a second installation later. Where budgets are tight, a 1Gbps bearer with a lower committed rate gives you the upgrade path without the full gigabit price today.
How to get the best 1Gbps price
Commit to a 36-month term, check whether an alt-net already serves your postcode, and compare every carrier rather than accepting one rate card. AMVIA runs that comparison across BT Openreach, Virgin Media Business, CityFibre, Zayo and others, surfaces any construction charges upfront, and manages the 30–90 working-day install end to end. Start with your postcode — a tailored quote typically lands within 24 hours.
1Gbps Leased Line Cost FAQs
1Gbps leased lines start from £129 per month, with the sharpest pricing on alt-net routes such as CityFibre and Hyperoptic. Typical ranges are £129–£700 in London, £129–£800 in regional cities, and up to £1,200+ in semi-rural areas. Your exact price depends on which carriers have fibre near your building.
The lowest advertised pricing comes from alt-net carriers on postcodes their fibre already serves. Where your building sits relative to each carrier's network determines who can offer what — so two providers can quote very different prices for the same circuit. A multi-carrier comparison for your exact postcode resolves this.
For cloud-heavy teams, multi-team sites, or anyone moving large files daily, usually yes. In well-served urban areas the price gap between 100Mbps (from £69/month) and 1Gbps (from £129/month) can be under £100 per month for ten times the capacity — and it avoids paying for a second install when you outgrow 100Mbps.
Installation is typically £500–£2,000, though many carriers waive it on a 36-month contract. Where fibre must be physically built to your premises, excess construction charges of £500–£10,000+ can apply — these should always be surfaced by an availability check before you sign.
Like all leased lines, typically 30–90 working days from order to live service: desktop survey, physical site survey, fibre work where needed, then testing and cutover. A temporary 4G/5G router can bridge the gap if you need connectivity before the line goes live.
Yes. A 1Gbps leased line delivers 1Gbps upload and 1Gbps download simultaneously, uncontended, at all times — unlike gigabit broadband, where upload speeds are typically a fraction of the headline figure and bandwidth is shared with neighbouring premises.
