Opus Energy business gas: rates, renewals and bill audits
Opus Energy, part of Drax, supplies electricity and gas exclusively to businesses, with a large base of SME customers across the UK. We validate Opus Energy gas bills, recover overcharges and tender your renewal across the market so the price you pay is tested, not assumed.
What Opus Energy offers business customers
- Business-only supplier — no domestic customers
- Renewable-sourced electricity on standard business contracts
- Contracts commonly written on one to five year terms
Opus Energy gas charges we most often challenge
Most business gas overcharging is not the unit rate — it is what sits around it. On Opus Energy accounts these are the recurring findings:
- Long fixed terms signed at a market peak
- Termination windows missed, triggering a further fixed term
- Security deposits held after payment history improved
Renewing a Opus Energy contract
Termination notice windows are strict. Diarise the window as soon as you sign, and tender before it closes.
We hold your contract end dates, alert you before the termination window closes and tender the requirement so Opus Energy has to compete for the renewal. Our service is free of charge to your business and you can cancel at any time.
How the review works
- You sign a Letter of Authority — nothing is undertaken without your written consent.
- You upload a recent Opus Energy bill. We read the MPRN, consumption, standing charges and contract dates from it.
- We validate every charge against the contract and the published market position.
- Recoverable errors go to Opus Energy as a documented dispute; the renewal goes out to tender.
- You receive the evidence pack, the market comparison and our recommendation in writing.
Opus Energy gas: frequently asked questions
- How do I get a cheaper business gas price from Opus Energy?
- Send us a recent bill and a signed Letter of Authority. We validate the current charges, then tender your business gas requirement across the market — including Opus Energy — so the renewal offer is tested rather than accepted.
- Can you challenge Opus Energy charges I think are wrong?
- Yes. We audit the bill line by line for long fixed terms signed at a market peak, termination windows missed, triggering a further fixed term and other recoverable errors, then raise a documented dispute with Opus Energy on your behalf.
- Do I have to leave Opus Energy to save money?
- No. Often the best outcome is a corrected, renegotiated contract with Opus Energy. We only recommend a switch when the market clearly beats what Opus Energy will offer.
- What do you need from me to start?
- A recent business gas bill, your site address, and a signed Letter of Authority. No work whatsoever is undertaken without your written consent, and you can withdraw it at any time.
- How long does a business gas review take?
- A bill validation is normally returned within a few working days. Recovery of a historic overcharge depends on Opus Energy's response times, but we chase it and keep you updated in writing throughout.
