If you’ve recently heard the words “Supplier of Last Resort” or seen it abbreviated as SoLR, chances are your energy supplier has, or, is about to stop trading. Find out what a SoLR is, how they can help you, and why getting one could be an opportune time to switch energy suppliers.

Supplier of Last Resort

From time to time, an energy company will cease trading. It could be that they’ve gone bust or have been acquired by another energy provider. If your supplier’s gone out of business, don’t panic. Your lights and heating will continue to work thanks to the supplier of last resort (SoLR).

What is a Supplier of Last Resort?

The supplier of last resort is both a procedure and an actual energy supplier, appointed by the UK energy regulator Ofgem.

When your energy supplier has gone out of business, you’ll usually receive a notification from them explaining why they’ve stopped trading and tell you who your SoLR is going to be. 

In some cases, your status will be termed as ‘Supplier of Last Resort or SoLR’. This means that Ofgem is still looking for a supplier to transfer your supply (and account) to.

Can you change your Supplier of Last Resort?

Yes. The role of the SoLR is to keep your energy supply ticking over but, you have the right to switch to another energy provider. In fact, we think that it’s a perfect time to reassess your energy deal and search for alternatives. 

Your SoLR will act in good faith to try and match your old deal but in some cases, you may end up paying more for your energy on your ‘deemed contract’. This is the type of contract (not tariff) you’ll be put on because your existing contract came to an abrupt end but you continue to use energy.

The good news is that under a deemed contract, you are free to switch energy suppliers straight away without incurring any exit or other types of fees. If you’re currently with a Supplier of Last Resort now’s best the time to check if there’s a better energy deal for you.
