About

Who is Opus Energy?

Opus Energy was an all-green UK business energy supplier that operated for around 20 years and grew to serve more than 340,000 business premises across England, Scotland and Wales. In 2015 it broke through the Big Six dominance of the business-energy market to become the UK's fifth-largest B2B supplier. Drax Group sold the entire SME customer book to EDF Energy in 2024, and Opus stopped trading later that year.

Registered as Opus Energy Limited, Opus Energy uses this legal name for Ofgem licence filings, B2B contracts and any formal communications. The trading name customers see on invoices is the shorter, recognisable form.

The company is headquartered in Northampton, where it runs its commercial operations, account management and regulatory liaison with Ofgem.

Opus Energy is part of the Drax Group (until 2024); SME book sold to EDF Energy group, which provides shared governance, financial backing and a wider pool of expertise in wholesale trading, hedging and regulatory work.

The company is regulated by Ofgem, and complaints fall under the Energy Ombudsman alternative dispute resolution scheme,but only for microbusinesses with under 10 staff and under £2m turnover. Larger I&C customers must take complaints through commercial dispute resolution.

Review

Opus Energy,pros and cons

Opus Energy carved out a credible niche as the UK's fifth-largest business energy supplier with a 100% renewable mix, but customer-service quality slipped sharply in the last years before the EDF transfer. Former customers should diary their inherited contract end date and compare the market in the 60-120 day renewal window before EDF rolls them onto out-of-contract rates.

Strengths

  • 100% renewable electricity backed by REGO certificates across the supply book.
  • Strong renewables ecosystem: more than 2,100 UK wind, solar, hydro and anaerobic-digestion generators sold output to Opus under PPA contracts.
  • My Opus Energy portal supported account management, meter readings and consumption tracking.
  • Won the Utilities Provider of the Year award in 2017 during a period of customer-service-led growth.

Watch-outs

  • Trustpilot reviews turned negative in the supplier's final years, with about 48% rating Opus "Bad" against 39% "Excellent".
  • Recurring complaints about incorrect invoices and customer-service responsiveness.
  • No longer trading — all customer service now sits with EDF Energy.

Common questions

Opus Energy,frequently asked questions

No. Opus Energy stopped trading in 2024. Drax Group sold the entire Opus SME customer book to EDF Energy, with around 90,000 SME meter points transferred, and the Opus brand was wound down. New business customers can no longer sign up with Opus, and its customer service now runs through EDF.

Business customers were transferred to EDF Energy. Fixed-rate Opus contracts kept their original price for the remainder of their term, while variable and out-of-contract customers moved to the closest EDF equivalent. Supply was never interrupted. Power Purchase Agreement generators were not transferred and remain with Drax.

Opus built a strong reputation on a 100% renewable electricity mix and won Utilities Provider of the Year in 2017. In its final years, however, Trustpilot reviews turned negative, with around 48% rating it "Bad" against 39% "Excellent", and recurring complaints about incorrect invoices and customer-service responsiveness. Our verdict: strong green credentials, weaker service in the run-up to the EDF transfer.

Yes. Opus Energy supplied both electricity and gas to businesses of all sizes. Small and medium businesses could take Standard Fixed contracts, typically over three years, while large and corporate customers had access to Opus Fixed, Opus Evolution (flexible electricity above 5 GWh per year) and Corporate Gas. All electricity was 100% renewable, backed by REGO certificates.

The original My Opus Energy portal at www.opusenergy.com has been retired. Former customers now manage their account through EDF MyAccount to view bills, submit meter readings and check usage. If you have not yet set up an EDF login, use the registration link on that page with the account details from your transfer letter.

Because Opus no longer trades, a "moving in" or "moving premises" request is now handled by EDF Energy for transferred accounts. Notify EDF of your move-in and move-out dates and provide opening meter readings so the supply is billed correctly. If you are moving into premises and simply want the best deal, you are not tied to a deemed contract, so compare the business market and switch before out-of-contract rates apply.
