Drax / Haven Power business gas: rates, renewals and bill audits
Drax, incorporating the former Haven Power business supply, provides electricity and gas to large industrial, commercial and multi-site UK organisations. We validate Drax gas bills, recover overcharges and tender your renewal across the market so the price you pay is tested, not assumed.
What Drax offers business customers
- Large industrial and commercial customer base
- Flexible purchasing and risk-managed products
- Haven Power contracts migrated into the Drax brand
Drax gas charges we most often challenge
Most business gas overcharging is not the unit rate — it is what sits around it. On Drax accounts these are the recurring findings:
- Legacy Haven Power references creating billing mismatches
- Capacity charges on sites with reduced demand
- Half-hourly data gaps leading to estimated settlement
Renewing a Drax contract
On large sites, an authorised capacity review often saves more per year than a rate renegotiation, and it can be done mid-contract.
We hold your contract end dates, alert you before the termination window closes and tender the requirement so Drax 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 Drax 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 Drax as a documented dispute; the renewal goes out to tender.
- You receive the evidence pack, the market comparison and our recommendation in writing.
Drax gas: frequently asked questions
- How do I get a cheaper business gas price from Drax?
- 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 Drax — so the renewal offer is tested rather than accepted.
- Can you challenge Drax charges I think are wrong?
- Yes. We audit the bill line by line for legacy haven power references creating billing mismatches, capacity charges on sites with reduced demand and other recoverable errors, then raise a documented dispute with Drax on your behalf.
- Do I have to leave Drax to save money?
- No. Often the best outcome is a corrected, renegotiated contract with Drax. We only recommend a switch when the market clearly beats what Drax 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 Drax's response times, but we chase it and keep you updated in writing throughout.
