Full-fibre coverage is 0.1 percentage points higher than the published London figure of 78.4%. Gigabit-capable coverage is 0.7 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 Lewisham.
Lewisham, Catford, Brockley, Forest Hill and Sydenham provide useful local reference points, but broadband service is still decided at the address. For properties near Deptford or another borough boundary, use the full postal record instead of guessing from the neighbourhood. Before switching, establish whether a new network requires an installation and whether the building owner needs to approve it. If your current service is already full fibre, compare practical upload needs, support and indoor coverage before paying for more download bandwidth.
Look at the building as well as the street.
- For a Brockley or Forest Hill conversion, check that the flat appears separately in the provider’s address list.
- For a Lewisham or Catford apartment, confirm who can unlock communal access on installation day.
- For a Sydenham home with an upstairs office, compare Ethernet performance with the signal in that room.
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 Lewisham address.

Your local questions, answered.
If I already have FTTP, is a higher speed tier the obvious upgrade?
Only if the current bandwidth is limiting the way you use it. Larger downloads may finish sooner, but poor Wi-Fi, device limitations or congestion elsewhere can remain. Compare the activities that overlap in your home, the upload rate and the equipment you actually use.
What does the Lewisham 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.
