Full fibre describes the access technology. Gigabit capable describes speed capability and can include cable. The measures overlap and should not be added together.
How City of London compares with London.
Full-fibre coverage is 3.9 percentage points higher than the published London figure of 78.4%. Gigabit-capable coverage is 8.2 percentage points lower than London’s 90.8%.
Both comparisons use the January 2026 all-premises snapshot. The London figures are published regional statistics, not an average of borough percentages. This compares area coverage, not provider quality or service at an individual address.
Connecting in City of London.
The Square Mile is a separate local authority from the surrounding London boroughs. A home in the Barbican, an office near Bishopsgate and premises around Smithfield can have very different ordering and access arrangements. Start with the exact unit rather than assuming a building’s commercial connectivity is also offered to its residents. For offices, decide whether you need ordinary business broadband or a dedicated leased line: an attractive download speed does not establish the support hours, repair commitment or upload capacity your business needs.
Look at the building as well as the street.
- For a Barbican or Golden Lane flat, ask the estate or building manager who can approve shared-area cable access and appointments.
- For an office suite, confirm the quoted service terminates inside your unit rather than at a landlord-managed building handover point.
- If a reception team controls access, include their appointment requirements when booking the installation.
Before you order.
Use these checks to turn the local picture into a decision for your property. Keep the written address-specific quote and installation details together.
- Search the complete house, flat or business-unit address on the network checkers.
- Confirm full fibre, part fibre or cable, plus both download and upload speeds.
- Check any installation permission, engineer appointment and router location.
- Compare the total contract cost, minimum speed commitment and moving-home terms.
Check broadband at your City of London address.
These official checkers are starting points for London addresses. A link here does not mean that the operator covers your street or building. Select the complete property address, including your flat or unit number.
Openreach is a wholesale network: if it can serve your address, compare retail providers using that network. Read the network and provider guide.
Your local questions, answered.
Does an office building’s fibre connection mean my flat can order it?
No. Residential and commercial units can have separate address records, contracts and installation routes. A leased line installed for a business also does not make ordinary home broadband available to other units. Ask the network to check your complete residential address.
What does the City of London coverage figure tell me about my address?
It describes the share of premises covered across the local authority in January 2026. It cannot identify the network at your property or confirm a live order. Check your exact address with the network and chosen provider, including the flat number where relevant.
