Short answer

Check what is available at the new postcode before you commit to a provider, then order at least three to four weeks before you move. Ask whether an engineer visit is needed — that is what sets the lead time — and check whether moving your existing service is cheaper than cancelling and restarting.

Broadband is the one utility that cannot be switched on with a phone call on moving day. Where a new line, a new technology or an engineer appointment is involved, the lead time is measured in weeks, and it is set by the network rather than by the provider you buy from. Ordering early is the whole trick.

Step by step

  1. Check what the new address can actually take.Use an availability checker on the exact postcode and house number. Full fibre, part-fibre and older copper services differ street by street, sometimes house by house.
  2. Ask whether an alternative network serves the street.Some addresses are served by networks that do not appear on the main comparison sites. It is worth a search on the street name.
  3. Ask your current provider what moving costs.If you are mid-contract, moving the service is often cheaper than cancelling. Ask about the early termination charge either way and compare.
  4. Order three to four weeks ahead.Longer if a new line is being installed. Providers will book an activation date in the future, so ordering early costs nothing.
  5. Find out whether an engineer visit is required.A live line that only needs activating can be days. A new installation needs an appointment, and appointments are the bottleneck.
  6. Ask the previous occupier or the seller what they had.Knowing the existing technology and where the socket is saves a great deal of guessing, and tells you whether a line is live.
  7. Arrange a stopgap.Mobile tethering or a data SIM for a few weeks is far cheaper than rushing an installation, and it removes the pressure entirely.
  8. Check the old service's end date.Do not let it end before the new one starts, and do not let it run months beyond the move. Both are common and both cost money.
  9. Confirm the appointment the week before.Installation appointments get moved. A confirmation call the week before finds it while there is still time to react.
  10. Test the speed once installed.Do a wired test in the first week and keep the result. If it is well below the guaranteed minimum, the clock on your remedies starts from reporting it.

Tips

  • The availability checker result for the house next door does not necessarily apply to yours. Always check the exact address.
  • If you are buying, ask the estate agent to ask the seller what service they used and where the master socket is.
  • Ordering early is free. Ordering late is either expensive or slow, and often both.

Common mistakes

  • Waiting until after the move to order — Where a new line or an engineer appointment is needed the lead time is weeks, and nothing you do afterwards shortens it.
  • Cancelling the old service before the new one is live — It removes any fallback and can trigger an early termination charge that moving the service would have avoided.

If it doesn't work

The installation date is weeks after your move

Cause: An engineer appointment is required and slots are scarce — Fix: Take the slot, and bridge with mobile data. Ask to be added to any cancellation list.

The provider says the address does not exist

Cause: A new build or a converted property not yet on the address database — Fix: Ask the provider to raise an address-matching query, and give them the postcode plus the developer's plot reference if it is a new build.

You are mid-contract and moving

Cause: The contract does not end because you moved — Fix: Ask about a house move rather than a cancellation — most providers transfer the contract, sometimes with a new minimum term.

Questions people ask

Does moving house let me leave a broadband contract early?

Not automatically. If the provider cannot serve the new address, an exit without penalty is usually available; if they can, they will normally expect the contract to move with you. Ask them directly.

Is full fibre worth waiting for?

If it is available and the price is similar it is generally more reliable, because it removes the copper section that causes most faults. Whether it is worth a delay depends on how long the delay is.

Can I keep my landline number?

Often yes within the same area and provider, but not always across technologies or areas. Ask before you order if the number matters.
