Switch broadband in the UK: factual, step-by-step guide
Use this guide to switch broadband with confidence. It reflects common UK processes including One Touch Switch, cooling off rights and address-level availability checks.

1) Check availability by postcode
Availability changes street by street. Enter your postcode in the comparison to see deals that actually serve your address, with average speeds, total monthly price, contract length, setup costs and any router or installation fees.
We do not store postcode data outside the comparison flow.
2) Compare on total cost and policy
- Total cost: add monthly price across the term plus setup and delivery; subtract any bill credit.
- Contract term: 1, 12, 18 or 24 months are typical.
- Price change policy: some deals have a stated annual rise; others are fixed for the term.
- Speed fit: choose a package that meets household demand; full fibre or cable is usually most reliable where available.
- Extras: Wi-Fi pods/guarantee, TV bundles, or mobile plan discounts can change the value.
3) Place your order
Complete sign up online with the new provider. Within Openreach, One Touch Switch means the new provider usually arranges the transfer date. Keep your preferred email and mobile handy for updates and router delivery notices.
- Number porting: ask to keep your landline number during sign up if you need it.
- Engineer visits: common when moving to full fibre, cable, or where a new line is required.
- Self install: available for many FTTC and some fibre or 5G home broadband options.
4) Go live and verify
On activation day, downtime is usually brief. Plug in the supplied router or hub when instructed. Test speeds on Ethernet if possible.
- Cooling off: online and phone orders carry a 14 day cooling off period.
- Minimum speed guarantee: most providers state a minimum; if they cannot meet it after troubleshooting, you may be able to leave without penalty.
- Overlap: if changing networks (e.g., to/from cable or 5G), consider a 1–2 day overlap to avoid gaps.
Quick checklist before you switch
- Check if you are out of contract to avoid or minimise exit fees.
- Confirm total first-year cost, setup/installation, and whether the price is fixed or has a stated annual rise.
- Note the activation date and whether an engineer visit is required.
- Request landline number porting during sign up if needed.
- Return old equipment if asked to avoid charges.
FAQs on switching broadband in the UK
How long does a switch take?
Many switches complete within 1–2 weeks. Openreach to Openreach moves often need only a brief downtime window. Cross-network moves can vary depending on engineer availability or hub delivery.
Do I need to cancel my old service?
Within Openreach, your new provider usually handles the transfer. If moving to or from a different network (e.g., Virgin Media or 4G/5G home broadband), you may need to cancel the old service after the new one is live to avoid overlap charges.
What if the new speed is lower than expected?
Test on Ethernet soon after activation. If speeds stay below the guaranteed minimum after troubleshooting with the provider, you may have options to leave without penalty.
Can renters switch?
Yes. Shorter terms and 4G/5G home broadband can suit renters. Check any installation permissions in your tenancy before ordering fixed-line installations.
