What’s happening
E.ON has agreed to buy OVO, and the deal received competition clearance in early October 2026. Reports put E.ON’s household customers at around 5.6 million and OVO’s at around 4 million, which would make the combined business one of Britain’s largest suppliers. Completion is expected later, with Which? suggesting by the end of the year.
If you’re with OVO
- Nothing changes until the deal completes: same account, payments and contact details.
- Your tariff, including any fix, is honoured until its end date.
- Your supply won’t be interrupted.
- You can still switch away if you find a better deal (check exit fees on fixes).
- Take a meter reading and a screenshot of your balance, so you have a record of any credit or debt.
Should you switch now?
Only if there’s a better deal for you. Compare tariffs as usual using our deal checklist and see all UK suppliers.
