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 Merton compares with London.
Full-fibre coverage is 3.2 percentage points higher than the published London figure of 78.4%. Gigabit-capable coverage is 3.9 percentage points higher 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 Merton.
For Wimbledon, Mitcham, Morden, Colliers Wood or Raynes Park, inspect the available network rather than assuming one borough-wide broadband offer. Merton’s official full-fibre and gigabit figures are useful for comparing the area, but they cannot predict an individual installation. For a household with work calls during the day and streaming in the evening, check the likely overlap. A 100 or 300 Mbps package may already cover ordinary activity comfortably; higher tiers become more valuable when frequent large transfers need to finish quickly.
Look at the building as well as the street.
- For a Wimbledon or Raynes Park home, choose a router location that reaches the rooms where calls and streaming actually happen.
- For a Colliers Wood flat, ask about the network installed in the block and any access arrangements.
- For a Mitcham or Morden move, confirm whether the new address needs an engineer or simple activation.
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.

Your local questions, answered.
Does a household need gigabit just because several people live there?
No fixed household size requires a particular tier. Concurrent activities, file sizes, upload demand and waiting-time expectations matter more. Work through an activity estimate, leave room for background use and compare the next speed tier’s cost with the time it would realistically save.
What does the Merton 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.
