Should I change my energy supplier when I move house?

Moving house is a great opportunity to see if you can get a better deal on your gas and electricity.

When you move into your new home, the existing energy supplier will often put you on what's called a 'deemed contract'. This can be one of the more expensive tariffs, so you might want to start shopping around as soon as possible.

How do I choose a new energy supplier?

It's easy. You can use our energy comparison service, to get a range of quotes from energy providers. Just give us your new postcode and a few details about yourself, and we'll do the rest.

What steps do I need to take before I move house?

Before you leave your old home, there are a few things you'll need to do:

  • Consider your options

Check your existing tariff to see if there's an exit fee. Then compare your tariff against other deals available and work out if it's cheaper to take your existing tariff with you when you move, or switch after paying any exit fee.

If your comparison results show you're better off staying with your existing tariff, let your supplier know two weeks before your moving date so they can prepare to move your account to your new address. If it's cheaper for you to switch, tell your supplier at least 48 hours before you move and confirm the date. They can then send the final bill to your new address.

  • Take meter readings on the day you move

Take meter readings at your old and new house on the day you leave. You don't want to be charged for someone else's energy use, so take the readings as soon as you move in to cover yourself in case you get an unexpected bill. Taking readings will also stop you being overcharged and will offer you some protection if you don't agree with your final bill. You may even find that you're owed money on overpayments, which you can claim back by calling your supplier.

  • Compare suppliers and switch

If you've cancelled your previous tariff, find out who the energy supplier is at your new property. You can then compare energy providers and switch to the right tariff for you. Your new supplier will handle the switch – you'll be notified if you need to submit a meter reading or if they need anything else.

How do I find out who supplies the energy in my new home?

If you're not sure who supplies the property, don't worry – it's easy enough to find out.

To track down your gas supplier, give the Meter Number Helpline a call, on 0870 608 1524.

To find out who provides your electricity, you'll need to call the Local Distribution Centre (LDC) for your area, on one of the following numbers:

  • London, South East and Eastern England: 0800 029 4285
  • South West England, South Wales, West & East Midlands: 0800 096 3080
  • Southern England: 0800 048 3516
  • North West England: 0800 195 4141
  • Merseyside, Cheshire, North Shropshire and North Wales: 0330 1010 300
  • North East England and Yorkshire: 0800 011 3332
  • Central and Southern Scotland: 0330 1010 300
  • Northern Scotland: 0800 048 3515

Can I change my energy supplier if I rent?

If you're moving into a rented home and pay for your own gas and electricity, you have the right to change energy supplier.

It may say in your contract that your landlord has a preferred supplier, but that's unlikely, and it doesn't mean you can't switch. Ask your landlord about changing suppliers.

Do I need to tell my current energy supplier if I decide to switch?

No, you don't. Thanks to the Energy Switch Guarantee, switching is hassle-free and your new supplier will inform the old one on your behalf. The guarantee also means there are no fees to switch, and the process should take no more than 21 days.
