Fibre or Standard Broadband in the UK: Full Fibre, Part Fibre and What Reaches Your Home

UK broadband reaches a home in one of four ways: standard broadband over the copper phone line, part fibre to the street cabinet, full fibre all the way to the building, or cable. Which of them you can get depends on your address, and the difference that matters most is how far the copper goes.

The four types

• Standard broadband (ADSL). Copper all the way from the exchange. The slowest type, and its speed falls the further you are from the exchange.
• Part fibre (fibre to the cabinet). Fibre to the green street cabinet, copper for the last stretch. Speeds fall with distance from the cabinet.
• Full fibre (fibre to the premises). Fibre all the way into the building. The fastest and most consistent, and some plans upload as fast as they download.
• Cable. A separate network that reaches parts of the UK, with fast download speeds.

Finding out what reaches your home

Enter your address in a provider’s availability check: it shows which type reaches the building and the speed the provider expects to give you. Two neighbouring streets can have different options, and a new-build may have full fibre from the start.

When the type matters

• Several people streaming, gaming or on video calls at the same time.
• Working from home, especially sending large files, where upload speed counts.
• A home far from the street cabinet, where part fibre can be slow.
• The landline switch-off: home phone lines are moving to digital services over broadband by January 2027.

For light browsing and email, a slower connection can be enough. Choose for the busiest hour in your home, not the average one.

Before you move to full fibre

• Check the contract length and any exit fee on your current plan.
• Ask whether installation needs an engineer visit, and whether there is a setup fee.
• If you rely on a landline or a telecare alarm, tell the provider: a digital line needs power.

How Wisemium helps

Wisemium shows broadband plans from the providers it works with, not every plan on the market, with each plan’s speed, monthly price, contract length and any stated price rise. Add your broadband to Wisemium and the price and the contract end date are kept on record, so you can see when it needs attention. Wisemium does not provide broadband itself.
