Business utility bill audits and refunds

Wrong rates, estimated reads that never got corrected, VAT at the wrong percentage. An audit finds the money hiding in your bills, and stops the leaks going forward.

Somewhere in the last few years of your utility bills there’s a fair chance money is hiding. A bill audit puts your contract next to what you were actually charged, line by line, and claims back the difference.

Quick snapshot

  • Most refunds come from unglamorous errors: estimated reads, misapplied rates, wrong VAT or CCL treatment.
  • Reputable audit work is paid from what’s recovered. No find, no fee.
  • The bigger win is usually the charges you stop paying, not the ones you claim back.

How can I check if my business is owed a utility refund?

Put your contract next to your last twelve months of bills and check three things: the unit rate and standing charge match what you signed, the meter readings are marked actual rather than estimated, and VAT plus Climate Change Levy are applied at the right rate for your use. Anything that doesn’t line up is a potential claim.

The common finds are unglamorous. An estimated read that ran high for a year, a contracted rate applied a month late after a switch, a 20 per cent VAT rating on a site that qualifies for 5, credit sitting on a closed account nobody chased. None of them announce themselves on the bill.

How do I know if my business utility contract is overpriced?

Benchmark it. Take your annual consumption and your current rates, and get a live quote for the same term. If the market is meaningfully below what you’re paying and your contract end date is in range, you’re overpaying, and if you’ve rolled over without comparing for a couple of renewals, you almost certainly are.

The two states to check first: out-of-contract rates after a lapsed renewal, and deemed rates where no contract was ever agreed. Both are priced at the expensive end of the supplier’s book and both are fixable within weeks.

What is a professional business water audit?

A line-by-line review of your water and wastewater charges against what the site actually uses and how it’s classified. Since the business water market opened, charges carry a negotiable retail layer, and the underlying data is wrong more often than you’d expect.

Audits regularly turn up surface water drainage billed on the wrong basis, incorrect rateable values driving fixed charges, unnoticed leaks, and trade effluent misclassification. Our business water team runs these alongside bill validation on energy, because the method is the same even where the tariffs aren’t.

Do utility brokers charge upfront fees for audit services?

The reputable end of the market works on recovery. A share of what’s actually found and returned, with nothing payable if the audit comes back clean. That aligns everyone’s incentives, and it’s how we work. The commission and fee structure behind all our services is published on how we make our money.

Claim back, then stop the leaks

Audit findings split roughly into two piles: money to claim back, and charges to stop paying going forward. The second pile is usually the bigger one, which is why an audit pays for itself even when the refund is modest.

Frequently asked questions

How far back can a business claim a utility refund?

Billing errors can often be challenged going back up to six years, depending on the circumstances and what the contract says. The paperwork matters more than the principle, which is why an audit starts by assembling old bills and contracts before anyone talks numbers.

What do you need from us to run a bill audit?

A signed letter of authority so we can pull data from your suppliers, plus your most recent bills. Twelve months’ worth is ideal. From there the work happens on our side, and most of it is checking rates, reads and charges line by line.

Do utility brokers charge upfront fees for audit services?

Reputable ones don’t. Audit and refund work is usually done on a share of what’s actually recovered, so if nothing is found, nothing is owed. Anyone asking for an upfront audit fee should be able to explain exactly why. Our own basis is on how we make our money.

What are the most common overcharges an audit finds?

Estimated reads that drifted from reality, unit rates that don’t match the contract, VAT charged at 20 per cent where 5 applies, Climate Change Levy applied to exempt use, and on water, surface drainage charged on the wrong basis. Individually small, but they compound quietly across years.
