Full fibre broadband, explained in plain English

What full fibre actually is, how much speed your household needs, who can connect your street, how to switch without overpaying, and what happens when the engineer arrives. Sourced, dated and free of jargon.

We are an information site, not a provider or comparison site. We do not sell broadband, recommend deals or earn money from links. No advertising and no tracking.

Six rules of thumb

  • Read the label, not the word “fibre”

    Since 16 September 2024, Ofcom guidance has told providers to label every package as full fibre, part fibre, cable or copper. What each one means

  • Buy for your busiest hour

    Add up what your household does at once, then double it for headroom. For most homes that lands between 50 and 150 Mbps. Worked examples

  • Test with a cable first

    Wi-Fi is often the bottleneck. Plug a device into the router before blaming, or upgrading, your broadband. Why Wi-Fi slows you down

  • Check by full address

    Availability can differ between neighbouring houses, and checkers disagree. Check by full address, not postcode, and use more than one source. How to check

  • Compare the total cost

    Include the annual pounds-and-pence rise. A deal with no annual rise can be cheaper than one that starts lower. Comparing deals

  • Choose where the box goes

    Pick a central spot near a double power socket for the ONT and router. That decision affects your Wi-Fi for years. Where to put it

How the guides are made

  • We start from primary sources: Ofcom, GOV.UK, the network operators and providers' own published terms.
  • Every guide shows when its facts were last checked and lists every source it relies on.
  • Figures that change, such as coverage, price rises and compensation, are dated in the text.
  • No provider pays to appear here. We do not use affiliate links, sponsored content or ads.

Getting full fibre installed?

The installation guide covers preparing for the engineer, where to put the ONT and router, permission if you rent or live in a flat, and what happens to your landline. It ends with a checklist for before, during and after the visit.
