After a period of relative stability in the UK energy market, the unfortunate collapse of Rebel Energy marks a significant disruption for many consumers. The collapse of Rebel Energy ends a long lull in supplier failures, with the last occurrence dating back to early 2022. Rebel Energy, serving around 90,000 customers, cited a "perfect storm" of soaring wholesale prices and increased financial pressure on consumers as key factors for its demise. This news is particularly shocking given that it coincides with the latest increase in energy bills, driven by a 6.4% rise in the energy price cap to £1,849.
UPDATE: On 7th April 2025, Ofgem announced that British Gas will take on the 90,000 Rebel Energy customers under their Supplier of Last Resort programme. More details on what to do next below.

If you're energy supplier has gone bust, it is important to know that your energy supply will NOT be interrupted. In terms of next steps, the best advice is to wait. This is because Ofgem (the energy regulator) will find a suitable new supplier for you under their dramatically named 'Supplier of Last Resort' (SoLR) programme. Due to the risk of your switch causing issues whilst the new supplier takes over, you shouldn't do anything until the new supplier has been confirmed.
In the meantime, take a meter reading as soon as possible and wait to be contacted by your new energy supplier. Once confirmed, you can switch to the new supplier's cheapest energy tariff, another tariff of your choice, or to a new energy supplier entirely. You will NOT face any exit fees that may have applied to your existing tariff. Equally, if you are in any credit with your existing energy supplier, this will be protected and honoured under the SoLR safety net.
If you're unsure on what to do, once your new energy supplier has been confirmed, you can compare energy prices and see if a new energy supplier is a better option for you or whether you should remain with the newly appointed energy supplier.
For more information, check out our guide on what to do if your energy supplier has gone bust.
The table below shows the number of customers that have been displaced each year.

| 2025 | 90,000 |
| 2022 | 176,536 |
| 2021 | 4,312,200 |
| 2020 | 215,500 |
| 2019 | 472,580 |
| 2018 | 723,500 |
| TOTAL | 5,990,316 |
SSE has not gone bust; it was acquired by OVO Energy, thus it's now part of the OVO family. Customers of SSE should now engage with OVO for their energy needs.
No, OVO Energy is still operational. In fact, it has expanded by acquiring SSE's retail services, making it one of the prominent energy suppliers in the market.
Utilita is still in business, continuing to supply energy, particularly pre-paid gas and electricity to homes across the UK.
E.ON has not gone bust. It remains one of the leading energy companies in the UK, providing electricity and gas to a large customer base.
There's no current indication that E Energy is going bust. They are active and continue to supply energy services to their customers.
