When can I switch energy supplier without penalty?

If you’re currently locked into a contract, you may need to pay an exit fee to leave your current deal. If this is the case and the exit fee outweighs any savings, you’re best waiting until your contract is nearing its end. However, you won’t be charged for leaving your current energy supplier if you switch during the last 49 days of your contract.

When is the best time to switch energy suppliers?

When should you avoid switching energy suppliers?

It’s generally worth avoiding switching energy suppliers if you’re locked into a deal that means you’ll need to pay an exit fee or penalty to leave your current deal that outweigh and savings you could make. However, under Ofgem’s, licence conditions, suppliers cannot charge exit fees for switches within the 49-day ‘switching window’ before a fixed term contract ends.

How to find the best energy tariff for you

When you’re switching energy suppliers, your main motivation may be to save money but you may also want to consider: how good customer service is, how green the energy provider is and whether you can get any deals on smart-home products by signing up. Find out more in our guide How to choose an energy provider.

Should I switch to a fixed tariff?

Switching to a fixed tariff means you’ll have certainty about how much you’ll pay for your gas and electricity for the duration of the deal. But if the cost of energy falls you may not be able to switch to a cheaper deal without having to pay an exit fee. So check the energy provider’s terms. However, if you choose to take out a variable rate deal, while the cost of energy may reduce in the future it could also go up.   

Can I change energy supplier if I’m in debt?

You can switch energy suppliers if you’ve been in debt to your supplier for less than 28 days. Your old supplier will add any owed amounts to your final bill.

However, you’ll need to repay a debt first if you’ve owed money for over 28 days. If you’re on a prepayment meter, you can still switch energy suppliers if you owe your supplier up to £500 for gas and £500 for electricity. Find advice on all of these issues on the Ofgem website.

Can I switch suppliers if I’m renting?

Yes, as a tenant you can switch energy suppliers if you pay energy bills to the supplier directly. Although it’s a good idea to tell your landlord if you’re switching suppliers. But if you choose to switch to an energy tariff that requires a smart meter to be installed, Ofgem recommends telling your landlord first ‘because there may be rules in your tenancy agreement about how energy is supplied to the property, including the type of meter that can be installed’.

But if your landlord pays for your energy use out of your rent, your landlord will need to make the switch. However, you can choose to ask them to switch providers.

How long does it take to switch energy suppliers?

A supplier has to switch a customer’s electricity or gas supply within 5 working days, as part of an energy supplier’s licence, says Ofgem.

However, during the switching process, you’ll be asked when you’d like to switch to your new tariff. You can choose to switch:

If there has been a delay and you haven’t been switched within 5 working days, contact the supplier to check they have all the information they need. If they do, they should automatically pay you £30 compensation by cheque or into your bank account.

Can I switch energy suppliers when I move home?

Yes, you can switch energy suppliers when you move home. You’ll need to take over the existing utilities when moving house, that doesn’t mean you can’t shop around for a cheaper or better supplier to switch to. Don’t assume the previous owner did their research and was on the best deal. 

Remember to tell your existing energy supplier that you’re moving house. You should give at least 48 hours’ notice. Also, give them your new address so they can send your final bill to you. And take meter readings on the day you move out of your old house and into your new one. For more information read our Moving house checklist and How to take over utilities when moving house guides.

Can I change my mind about switching energy suppliers?

When you switch energy suppliers, you’ll get a 14 day cooling-off period in which you can change your mind. This cooling-off period starts when you agree the contract, this applies whether it’s online, over the phone or face-to-face.
If you change your mind within the cooling-off period, you can:


If you switch energy suppliers and change your mind after the cooling-off period, you may need to pay an exit fee to leave your current deal.

Is it risky to switch to small energy suppliers?

If you’re worried about switching to a small energy supplier in case they go bust, rest assured that if this happens, you will be transferred to another energy supplier with a guarantee of no loss of gas or electricity supply.

What type of energy tariff can I switch to?

When you’re switching energy deal you’ll usually choose between fixed or variable rate, and by whether you want dual fuel (one bill for gas and electricity), single fuel (gas), single fuel (electricity), prepayment meter (pay as you go energy), an EV tariff, Economy 7 or Economy 10, these tariffs charge less for electricity at certain times of day, or a ‘green’ energy tariff, where the supplier commits to generating environmentally-friendly energy.

What information do I need to switch energy suppliers?
