What is an altnet? Independent full fibre explained
Quick answerAn altnet ("alternative network") is an independent company building its own full fibre network rather than using Openreach or Virgin Media. Examples include Hyperoptic, Community Fibre, Gigaclear, Trooli and Wildanet. Altnets often offer faster symmetrical speeds and lower prices, but only cover the areas they've built.
How altnets fit in
Most UK broadband brands rent lines from Openreach (BT's network arm) or run on Virgin Media's network. Altnets dig or string their own fibre, usually in specific towns, cities, blocks of flats or rural areas, and either sell broadband directly or let other providers use their network.
Why choose an altnet?
- Competitive prices, often with price-lock or low rises.
- Symmetrical speeds (same upload as download) are common.
- Local customer support.
- In rural areas, an altnet may be the only full fibre option.
Things to check
- Coverage is address-specific, so check your exact home.
- Fewer TV and bundle options than big brands.
- Switching between networks now works through One Touch Switch.
Examples
- Hyperoptic: gigabit fibre in apartment blocks and new builds in many cities.
- Wildanet: full fibre and wireless for rural Cornwall and Devon.
- Community Fibre (London), Gigaclear (rural southern England), Trooli, Brsk, Netomnia/YouFibre and many regional networks.
