Business Leased Line Costs 2026: What UK Businesses Are Actually Quoted

Quoted prices, not list prices: across the AMVIA corpus a 1Gbps leased line is quoted at a median of £319 a month (n=1,130), 200Mbps to 500Mbps at £282 (n=115) and 100Mbps at £287 (n=131), all contract terms, as of 8 August 2026. AMVIA's from-prices are £69 a month for 100Mbps and £129 for 1Gbps on 36-month terms in well-served postcodes. Installation is typically £500 to £2,000 and often waived on longer terms.

There is no single meaningful average, because a leased line is priced per address and the same circuit can be quoted hundreds of pounds apart on different streets. The honest anchors are medians with their sample sizes: £319 a month for 1Gbps (middle half of quotes £285 to £358, n=1,130) and £287 for 100Mbps (n=131), AMVIA corpus as of 8 August 2026. The UK Business Connectivity Pricing Index publishes the full quoted-price distributions by region.

The UK median quoted price for a 100Mbps leased line is £287 a month, with the middle half of quotes between £242 and £326 (n=131, all terms, AMVIA corpus as of 8 August 2026). AMVIA's from-price is £69 a month on a 36-month term in well-served postcodes. The regional breakdown is on the 100Mbps leased line cost guide.

The UK median quoted price for a 1Gbps leased line is £319 a month, with the middle half of quotes between £285 and £358 (n=1,130, as of 8 August 2026). London has the lowest regional median at £294 (n=291). AMVIA's from-price is £129 a month on a 36-month term. It is the most-quoted tier in the corpus by a wide margin, and it is quoted only a little above 100Mbps.

The corpus groups everything above 1Gbps (2Gbps to 10Gbps) into one band, quoted at a UK median of £297 a month with the middle half between £237 and £477 (n=602, as of 8 August 2026). The median is below 1Gbps because most multi-gigabit quotes are for well-served city postcodes; a 10Gbps circuit at a harder address sits at the top of that range. AMVIA's 10Gbps from-price is £349 a month. The multi-gigabit cost guide has the regional detail.

Excess construction charges are one-off costs a carrier quotes when new fibre has to be physically built to reach your premises: digging, ducting or new poles. Most orders carry none, but across UK leased-line orders that attracted one the median quoted ECC is £2,197, the middle half run from £348 to £7,412 and one in ten exceeds £16,000 (n=97, as of 8 August 2026). They only surface after a site survey, which is why any comparison should put ECC exposure in writing before you sign.

Delivered 1Gbps leased lines ordered between 2023 and 2025 took a median of 78 days from order to live (n=101, AMVIA corpus as of 8 August 2026); the band above 1Gbps took 93 days (n=38). Sites with existing fibre in the building are faster; anything needing a wayleave or civil works is slower. The carrier's quoted lead time is a target, not a commitment, so ask what the compensation is if it slips.

Yes, and the best moment is renewal: 58.4% of the live circuits tracked in the corpus are past their minimum term (n=1,338, as of 8 August 2026), usually still paying the rental they were sold at years ago. Carriers price 36 to 60 month contracts materially below 12-month terms and usually waive installation. A competing quote for the same postcode is the lever: the incumbent will match a cheaper on-net carrier more often than it will cut unprompted.

Yes - many providers waive installation fees on 36-month contracts in areas with existing fibre infrastructure. Longer terms (60 months) may also include ECC waivers and installation fee reductions. AMVIA negotiates the best terms across all carriers.

London businesses benefit from market-leading competition with dense fibre coverage from multiple carriers including BT, Virgin Media, Colt, CityFibre, and Vorboss. This ensures lower ongoing costs and often reduced or waived installation fees for standard urban deployments.

The initial quote assumes standard delivery. The survey establishes what the build actually requires - duct condition, wayleaves, any civil works - and excess construction charges are added where the assumptions don’t hold. Quotes at postcodes with existing on-net fibre rarely move; quotes needing new dig can. Always ask whether a quote is pre- or post-survey when comparing providers.

It should - a static IP allocation is standard on a business leased line, along with a managed router and an SLA with service credits. If any of those appear as paid extras on a quote, that is a signal to compare further. Confirm what is bundled before signing rather than after.

It depends on what an hour of downtime costs you, not on headcount. A small firm that trades through cloud systems, takes payments online or runs its phones over the internet can lose more in one outage than the annual premium over broadband. A small office that mainly browses and emails is usually better served by full-fibre broadband with a 4G/5G backup.

Three levers set the floor: pick the lowest bandwidth that genuinely fits (100Mbps from £69/month covers most sub-50-user businesses), commit to a 36-month term, and compare every carrier with fibre near your building rather than renewing with the incumbent - the cheapest network on your street is a postcode fact, not a brand. Watch the one-off costs too: a low monthly price with a large excess construction charge can cost more over the term.
