FTTP for London Businesses: The Ultimate Guide

The AMVIA Team · 9 min read · Updated June 2026

London is the most competitive broadband market in the UK. Dense existing infrastructure, high business demand and several competing network builders have produced a range of full fibre options that simply does not exist in most other UK cities. The flip side is complexity: availability changes street by street, and the best deal for your neighbour's building may not reach yours. This guide walks through the networks, the pricing, the borough-by-borough picture, and the point at which a leased line beats shared fibre. For a wider view of your connectivity options, start with our business broadband options overview.

Which FTTP networks operate in London?

London businesses can reach multiple independent full fibre networks alongside BT Openreach. That competition is unusual — most UK postcodes are served by Openreach and, at best, one altnet. In central and inner London, three or four networks may pass the same building, which is exactly why comparing quotes pays off here.

BT Openreach

Openreach is rolling out FTTP progressively across London, though its build in some inner-London areas has lagged behind regional cities — partly because building in a dense urban environment is slow and disruptive. Openreach FTTP reaches businesses through BT Business and hundreds of independent ISPs, and coverage is strongest in the outer boroughs. Ofcom's Connected Nations report tracks how far this full-fibre rollout has reached across the UK (Ofcom).

Community Fibre

Community Fibre is one of the most active full fibre builders in inner London. It owns its own infrastructure and offers gigabit-capable FTTP to businesses and residents across many London boroughs, available through ISPs that use its wholesale network. If you are in a flat-rich or mixed-use inner-London area, there is a good chance Community Fibre has already built past you.

Hyperoptic

Hyperoptic specialises in multi-dwelling buildings — office blocks, business parks and apartment buildings. It installs its own fibre internally and delivers symmetric gigabit connections, so upload speed matches download. If your London office sits in a modern multi-storey building, there is a reasonable chance Hyperoptic is already connected; it is always worth checking at the building level before assuming you need a new install.

Virgin Media Business

Virgin Media Business runs an extensive cable network across London. Its gigabit-capable product uses a hybrid fibre-coaxial network rather than pure FTTP, though performance is comparable for most business use cases. Virgin's footprint is strongest in residential areas but reaches many commercial properties within its coverage.

CityFibre

CityFibre dominates the independent altnet market in many regional UK cities, but its London presence is more limited. It continues to expand its capital footprint, so it is worth including in any availability check even where it was absent a year ago.

How much does FTTP cost for a London business?

Business FTTP pricing in London varies by provider, speed and contract term. As an indicative guide for 24-month contracts, expect business full fibre from £35/month, with gigabit packages sitting at the upper end of the range. London is one of the few UK markets where competition can pull these figures lower than the national norm.

Because several networks often compete for the same building, you can frequently negotiate below the list price. Always pull quotes from more than one network before committing — the gap between the cheapest and most expensive option for an identical address can be substantial. The government-backed Project Gigabit programme is also extending gigabit-capable coverage in harder-to-reach areas (gov.uk).

Where is FTTP available across London?

Availability varies significantly by borough and postcode, and the only definitive answer comes from an address-level check. The summary below shows the broad pattern, not a guarantee for any specific building — multi-tenanted properties in particular can break the rule for their whole street.

• Inner London (EC, WC, W1, SW1): Dense commercial areas with multiple networks often present. FTTP from Openreach, Community Fibre, Hyperoptic and Virgin Media Business is common, but availability still varies building to building.
• South London (SE, SW): Community Fibre and Openreach are both active. Coverage is patchier than central London but improving steadily.
• East London (E1–E17): Growing availability from Openreach and altnets. Tech-cluster areas such as Shoreditch and Hackney tend to be well served.
• North London (N, NW): Openreach FTTP is progressively rolling out, with Community Fibre present in parts.
• Outer London boroughs: Generally more reliant on Openreach, with availability improving as its full fibre programme completes.

Why do multi-tenanted buildings complicate London FTTP?

A large share of London businesses sit in multi-tenanted buildings where the landlord controls the internal infrastructure — and that control decides which networks you can actually reach. The wider street might have four networks, but if the riser only carries one, that is your real choice.

Some landlords hold exclusive arrangements with a single provider; others have installed building-level FTTP that multiple carriers can use. Either way, an external availability checker only tells half the story. If you are in a managed building, ask the building management team which networks are wired into the riser, then run an external check to confirm. Getting this wrong is the most common reason a London FTTP order stalls after it looks "available" online.

When should a London business choose a leased line instead of FTTP?

For businesses above roughly 40 staff, with mission-critical operations or heavy upload needs, a dedicated leased line provides guaranteed, uncontended bandwidth that shared FTTP cannot match. FTTP is contended — you share capacity with other users — so peak-hour performance can dip in dense areas.

London's density of carriers means leased line prices here are often lower than national averages for equivalent circuits. In the City and Canary Wharf in particular, 100Mbps leased lines are available from as low as £69/month. A leased line also adds a Service Level Agreement with guaranteed fix times — something no broadband product offers. If you are weighing the two, read what a leased line is and how an FTTP leased line differs from shared full fibre, then compare against the broader business leased line market.

For multi-site operators, a leased line backbone with dedicated internet access at the head office and FTTP at branches is a common, cost-effective pattern — see our guidance on multi-site connectivity.

How does AMVIA help London businesses get the right connection?

AMVIA checks FTTP availability across every major London network at once and compares pricing to find the best option for your exact address. For multi-tenanted buildings or complex requirements, we handle the building-infrastructure question as part of the review — so you are not left guessing what the riser actually carries.

One provider, security-first, Microsoft-certified: we treat connectivity as the foundation of a secure, well-run network, not a standalone commodity. That means the line we recommend fits the way your business actually works.
