About

Who is OVO Energy?

Registered as OVO Energy Limited, OVO Energy uses this legal name for Ofgem licence filings, contracts and any formal communications. The trading name customers see on bills is the shorter, more recognisable form.

The company is headquartered in Bristol, where it runs its senior management, customer operations and regulatory liaison with Ofgem.

OVO Energy was established in 2009. A longer track record means more years operating under Ofgem rules and a wider history of customer feedback, billing systems and regulatory interactions.

OVO Energy is part of the Imagination Industries Ltd (OVO Group) group, which provides shared governance, financial backing and a broader pool of expertise in trading, hedging and regulatory work.

The company is regulated by Ofgem, the UK's energy regulator, and its complaint handling falls under the Energy Ombudsman alternative dispute resolution scheme.

Who owns OVO?

CEO: Raman Bhatia (CEO since 2022); Stephen Fitzpatrick (founder, executive chairman)
Ownership: Privately owned
Listed: No (Imagination Industries is privately held)
Parent: Imagination Industries Ltd (OVO Group)
Big Six: Yes — historic Big Six member
Holders: Imagination Industries Ltd, the holding company controlled by founder Stephen Fitzpatrick. Mitsubishi Corporation holds a 20% minority stake acquired in 2019 for £200 million.

Fuel mix

OVO Energy electricity fuel mix

OVO matches 100% of standard-tariff electricity with REGO certificates (Renewable Energy Guarantees of Origin), so the headline supply is sold as "100% renewable electricity". Direct power-purchase agreements (PPAs) with named generators are limited to the Greener Energy add-on. Gas is mains gas by default; renewable / biomethane gas is only delivered via the paid Greener Energy add-on (≈£4 / month). The annual Ofgem-mandated fuel mix disclosure is published every July on ovoenergy.com/fuel-mix.

Current tariffs

OVO Energy tariffs: as of 14 May 2026

OVO Energy is a fully Ofgem-licensed domestic supplier, so its Simpler Energy standard variable tariff is capped quarterly by the Ofgem Energy Price Cap. Fixed tariffs and time-of-use add-ons (1 Year Fixed Energy, 2 Year Fixed Energy, Drive Anytime, Charge Anytime) sit outside the cap and can be cheaper or more expensive than Simpler Energy depending on wholesale prices. Rates below are the typical single-rate Midlands values for direct debit, excluding VAT, taken from the live ovoenergy.com price sheet on 14 May 2026. Your real region, your meter type and your annual kWh change the bill, so always run the Selectra comparator with 12 months of consumption before signing.

Where the energy comes from

OVO Energy generation portfolio

OVO's technology arm Kaluza sits at the heart of the brand's smart-grid story. It powers the Charge Anytime smart-charging scheduler, the Power Move rewards engine and the early UK vehicle-to-grid (V2G) trials. Together they let OVO turn an engaged smart-meter household into a flexible asset for the grid — and pay the household back in lower bills, account credits and free energy draws.

Common questions

OVO Energy — frequently asked questions

OVO Energy is regulated by Ofgem and operates under a standard domestic-supply licence. Whether it is the right supplier for your household depends on your unit rate, standing charge, customer-service rating and any add-on services (HomeCare, Warm Home Discount eligibility). Always quote your annual kWh consumption when comparing prices — the headline rate alone does not predict your bill.

Switching to OVO Energy takes about five working days under the new Faster Switching service, and your supply is never interrupted. Sign up online with your address, postcode and a recent meter reading. OVO Energy will arrange the transfer with your current supplier, including the final meter reading and the closing bill.

The UK grid is supplied by a mix of gas, nuclear, wind, solar, biomass and imports. OVO Energy declares its fuel mix annually under Ofgem rules — see the fuel-mix section above for the current figures. Some tariffs are sold as 'green' or '100% renewable', which means the supplier matches your annual consumption with renewable electricity certificates (REGOs) rather than physically delivering renewable electrons to your home.

Most UK fixed-term tariffs include an exit fee (typically £25-£75 per fuel) if you switch before the contract ends. You can switch without an exit fee in the last 49 days of your contract. Variable tariffs (including the default tariff capped by the Energy Price Cap) have no exit fees.

You can reach OVO Energy on 0330 303 5063, Mon-Fri, 9 a.m. to 5 p.m.. For a full breakdown of phone lines (emergency, prepayment, HomeCare, bereavement, Welsh, Relay UK), see the OVO Energy contact page.
