British Gas business gas: rates, renewals and bill audits
British Gas Business is the SME arm of Centrica and one of the largest suppliers of electricity and gas to UK businesses, serving everything from single-site shops to multi-site estates. We validate British Gas Business gas bills, recover overcharges and tender your renewal across the market so the price you pay is tested, not assumed.
What British Gas Business offers business customers
- Fixed and flexible contracts for micro-business, SME and corporate portfolios
- Online account with half-hourly data for HH-metered sites
- VAT reduced-rate and CCL exclusion handled by self-certification
British Gas Business gas charges we most often challenge
Most business gas overcharging is not the unit rate — it is what sits around it. On British Gas Business accounts these are the recurring findings:
- Deemed and out-of-contract rates applied after a contract quietly ended
- Estimated reads left in place for months on non-smart meters
- Standing charges billed on de-energised or vacated sites
Renewing a British Gas Business contract
Renewal offers are typically issued several months before the end date. Anything not actioned rolls to deemed rates, which are far higher than a tendered contract.
We hold your contract end dates, alert you before the termination window closes and tender the requirement so British Gas Business 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 British Gas Business 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 British Gas Business as a documented dispute; the renewal goes out to tender.
- You receive the evidence pack, the market comparison and our recommendation in writing.
British Gas Business gas: frequently asked questions
- How do I get a cheaper business gas price from British Gas Business?
- 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 British Gas Business — so the renewal offer is tested rather than accepted.
- Can you challenge British Gas Business charges I think are wrong?
- Yes. We audit the bill line by line for deemed and out-of-contract rates applied after a contract quietly ended, estimated reads left in place for months on non-smart meters and other recoverable errors, then raise a documented dispute with British Gas Business on your behalf.
- Do I have to leave British Gas Business to save money?
- No. Often the best outcome is a corrected, renegotiated contract with British Gas Business. We only recommend a switch when the market clearly beats what British Gas Business 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 British Gas Business's response times, but we chase it and keep you updated in writing throughout.
