About OVO Energy

OVO Energy was founded in 2009 in Bristol by Stephen Fitzpatrick, with the stated aim of making energy cheaper, greener, and simpler for UK households. The company grew steadily through the 2010s and became one of the UK's larger suppliers following its acquisition of SSE Energy Services in 2020, which added around 3.5 million customers to its base. OVO is currently the fourth largest electricity and gas supplier in the UK by customer numbers, serving approximately 4 million households.

OVO Energy is owned by Imagination Industries, which is wholly owned by Stephen Fitzpatrick, the company's founder.

In May 2026, E.ON announced an agreement to acquire OVO Energy in a deal expected to value OVO at up to £600 million. The transaction is subject to regulatory approval and had not completed as of June 2026. OVO and E.ON continue to operate independently until any such approval is granted and the deal formally closes. Customers of OVO Energy are not affected during this period.

Tariff types offered

OVO offers fixed rate tariffs locking in unit rates and standing charges for a set term, typically 12 months. Variable tariffs are available as a default option, subject to the Ofgem price cap.

OVO has previously offered a Better Energy tariff with 100% renewable electricity and carbon-offset gas. Its approach to green tariffs and REGO usage has evolved. OVO made a public commitment in 2023 to move away from standard REGO certificates toward more direct renewable sourcing. Check current tariff details for the current green energy position.

Prepayment tariffs are available for customers with pay-as-you-go meters.
