Can My Energy Supplier Stop Me From Switching?


Everyone goes through hard times and there is no reason to blame yourself for it. With that being said, if you’re currently in debt to your energy supplier and are struggling to keep up with payments, switching could be a good option as it could help you save money. So, let’s learn about switching in debt.

Can my energy supplier stop me from switching?

While there are extremely limited circumstances in which they can do so, unfortunately, your current energy supplier can block your switch. However, these circumstances aren’t common, and a large majority of energy switches take place without a hitch and are successfully completed within 17-21 days.

There are three main reasons why an energy supplier can (legally) block you from switching:

  1. If you owe your current supplier money, and have been in debt to them for more than 28 days
  2. If you’re on an unsupported meter
  3. (In very limited circumstances) if your home is rented.

If any of these points strike fear in you, don’t worry! Read on and we’ll talk you through them.

If you’ve been in energy debt for more than 28 days

The first point is that if you’ve been in debt for more than 28 days, it’s unlikely that your energy supplier will let you switch, and will move to stop you from switching. That doesn’t mean you’re stuck with that supplier forever, but you will need to get out of energy debt before being allowed to switch to a new supplier.

However, there are two key exceptions to this:

  1. If it’s not your fault that you’re in debt, and it’s due to an error on their side
  2. If you’re on a prepayment meter.

If your energy supplier has wrongly estimated your bills, this can be one reason why you’d be in debt. However, if it’s their fault or an error on their part – such as if you’ve supplied regular meter readings and they won’t change their estimates to reflect your proper usage – you’re still entitled to switch supplier. If you do end up owing them money once they’ve rectified the issue, this will be reflected in your final bill, which you will still have to pay back.

If you’re on a prepayment meter, and you’re in debt, you can switch supplier unless you owe more than £500 per fuel. However, you’ll need to ‘transfer’ this debt to your new supply and continue to pay by prepayment meter. This is the ‘Debt Assignment Protocol’.

If you’re on an ‘unsupported’ meter

Secondly, if you’re on an unsupported meter such as a prepayment meter, Economy 7 or Economy 10, your supplier may stop you from switching if your new tariff won’t support this. Some UK energy suppliers don’t have prepayment tariffs or Economy 7 or 10 tariffs – all of which require different rates and specific support than their usual tariffs.

If your home is rented

Last of all, if your home is rented, it may be harder to switch. But please be assured that this is in a minority of cases, not a majority. If you’re responsible for paying the bill and your name is on the bills, then switching energy supplier shouldn’t be a problem if you’re renting.
However, some landlords in rented or shared accommodation have their names on the bill, and if this is the case, you’ll need their permission to switch. If the energy supplier knows this, they may block your switch until they’re given permission by the landlord or homeowner.

What to do if your supplier is stopping you from switching

Can my energy supplier stop me from switching, if none of the above three criteria applies to you? This may be unlawful. As with all complaints, you’ll need to start by speaking to your current supplier, rather than heading straight to the Ombudsman.

More info

If you’re keen for Ombudsman involvement, you’ll need to prove to them that you’ve given your energy supplier the time to put things right, and that you’ve tried to come to a resolution with them.

When complaining to your energy provider, the following steps must take place:

  1. Speak to your energy provider’s customer service team, ideally over the phone where possible
  2. Your energy supplier then has a fixed amount of time to get back to you with a resolution or an update on your complaint until it’s resolved
  3. Within 8 weeks, you’ll either receive a ‘decision letter’ or a ‘letter of deadlock’ from them.

If you’re not satisfied with their solution after this process, or you don’t get a decision letter or letter of deadlock within 8 weeks, you can escalate this to the Ombudsman for impartial intervention. To get in touch with the Ombudsman Services, you’ll need to start using their online complaints service.

Do I need to contact my energy supplier when I switch?

Not usually, no. When you switch, often your new energy supplier will let your current energy supplier know of your intent to switch and their switchover date.

However, to ensure that the switch runs as smoothly as it can and that you get your final bill – which may include a refund to you – as soon as possible, it’s best practice to give them a final meter reading on switchover day.

Sometimes delays can be caused with final bills due to your new provider taking a while to share your final meter reading with them, so to keep everything running smoothly it’s best to give both energy suppliers the same meter reading on switchover day. Don’t forget that for dual fuel (gas and electricity) customers, you’ll need to provide one reading for each.
