Altnet broadband providers in London
London is home to many smaller full fibre broadband providers that offer ultrafast internet speeds for very competitive prices. Many of these brands also commit to no mid-contract price rises, unlike most of the large UK broadband providers.
Community Fibre
South England alternative provider Community Fibre is available to over one million properties in London. It offers full fibre-only deals for very reasonable monthly prices, often at a lower cost than many older, slower connections.
Those who can get Community Fibre often sing its praises - it also has a 4.6 / 5 rating on Trustpilot from over 50,000 reviews (as of February 2025), which is a far better score than the biggest UK providers.
Community Fibre's coverage is very evenly spread across the Greater London area, and no particular region of the city benefits more from its services than another.
However, it currently lacks adequate broadband coverage on the outskirts of the city near the M25, and in the following London areas:
- Ealing
- Wimbledon (west)
- Beckenham
- Sidcup
- Knightsbridge and South Kensington
- Highgate, Crouch End and Muswell Hill
Hyperoptic
Full fibre supplier Hyperoptic is another alternative broadband provider available across London. It supplies ultrafast broadband to hundreds of thousands of homes, mainly focusing on apartments and flat blocks.
Similarly to Community Fibre, the faster speeds it offers do not mean higher prices. If you choose one of its longer contract options, you'd end up paying a similar monthly fee to some far slower deals.
Hyperoptic broadband is usually found in more central areas of London than Community Fibre due to its main purpose of connecting flat buildings. As a result, it's mostly available in homes within TFL Zones 1 and 2 of the city, with availability more limited in outer areas.
Gigaclear
Mostly available across southern England, Gigaclear is another independent full fibre provider that offers reliable, ultrafast internet for very reasonable prices. While it doesn't fix its in-contract prices like other altnet providers, its pricing is still much more favourable compared to slower deals from most of the bigger providers.
Most of Gigaclear's coverage is outside of Greater London, but it has good availability in the northeastern areas of the city near the M25, namely in Chigwell, Buckhurst Hill, and Loughton.
4th Utility
Full fibre provider 4th Utility offers broadband services both via CityFibre and its own independent network. But since CityFibre doesn't have coverage in London, it is primarily available with its own network in the capital city.
Similarly to Hyperoptic, 4th Utility's network mainly connects flat blocks, which means its coverage is less widespread across the city as it focuses on multiple properties within one building. This means it's largely available in areas all over Greater London, with a number of connected buildings in the north, south, east, and west of the city.
However, 4th Utility does have a particularly high concentration of coverage in Woolwich and the Barbican.
Hey!Broadband
Alternative provider Hey!Broadband is available via F&W Networks, which also hosts broadband providers such as Link Broadband, Octaplus and Gigabit Networks.
Although it doesn't have widespread full fibre coverage across London, it has very high availability in the West London areas of Ealing, Southall, Greenford, and Alperton, in particular.
So far, this is the only area of London that can access Hey!Broadband. But if you live here, you'll likely be able to enjoy fast, reliable full-fibre internet.
