E.ON-Ovo £600m Deal Progresses with Customer Reassurance on Tariffs

E.ON's planned acquisition of Ovo Energy, estimated by media at up to £600m, has prompted assurances to Ovo's four million customers that tariffs and services will remain unchanged during regulatory review. The morning announcement detailed the deal's potential to create Britain's largest energy supplier by combining E.ON's 5.6 million customers with Ovo's base, amid Ovo's struggles with Ofgem resilience rules. Closing is expected in H2 2026 pending CMA approval, with E.ON shares up ~1.31% initially, though integration risks and scrutiny may limit market reaction in UK energy stocks and the UK 100.
