Moving house, same provider
By using the broadband checker, you’ll see whether your current internet service provider or ISP operates in your new area. If they do, and you’re happy with the service they’re providing, moving shouldn’t be a big deal. But it’s worth giving them a call to discuss the service you receive and any additional charges. If you’re moving from the city to the countryside then you may have an additional charge for using the internet in a rural area.
If you're only part way into a broadband contract, it almost certainly makes sense to stick with your current provider if possible, and simply move your existing contract to the new address.
Ending your contract early can result in cancellation penalties including paying up to the cost of all the remaining months of broadband and line rental you committed to.
Check with the provider that switching your contract to a new address won't start a new minimum contract term. If they tell you it will, there might be cheaper options available at your new address making it worthwhile to pay off the rest of your existing contract and sign up for a cheaper deal.
You’ll need to do the maths and work out if this is cheaper overall than paying for the extra months at the more expensive price.
Regardless, make sure you let them know. Each company will have a slightly different process with regards to house moves. Some like BT and Sky have their own moving portals that you can log in to. Here you’ll provide your move dates and leave them to get on with it. With others such as Virgin Media or Plusnet you’ll need to give customer services a call.
