Are your utility invoices actually right?

Compare each invoice line with the signed contract rather than with the previous invoice. Check that the unit rates and standing charges match the agreement for the period billed, that the meter readings are actual rather than estimated, that every supply number on the account is yours, and that any availability charge matches the capacity recorded for the site. A difference in any of those is worth questioning.

The first review across your invoices costs nothing. You see what reconciles against the contract and what does not before any fee is discussed. Where you then appoint us for ongoing validation or to pursue a recovery, the fee and how it is calculated are set out in writing and agreed before the work starts.

Once we hold the invoices, the contract and a signed letter of authority, the first read is usually a matter of days. Anything that depends on data only the supplier holds takes as long as the supplier takes to release it, and we tell you when that is what we are waiting on.

A recent full invoice for each meter, the supply numbers, the signed contract or the agreed rates, and a signed letter of authority. Nothing else, and no site visit is needed to begin.

Where an error is confirmed, the correction is normally issued as a credit against the account or as a repayment. How far back a supplier will reopen depends on the supplier, the charge type and the reason for the error, so the recoverable period is established as part of raising the query rather than assumed.

Pay the undisputed amount by the due date and raise the disputed portion in writing. Withholding the whole invoice usually creates a debt position that gets in the way of the query being answered.

Only where that has been agreed with you in writing first. We are paid either by a margin on the unit rate or by a fixed fee, and whichever applies is stated before anything is signed. There are no charges you have not seen in writing.

Yes. Cost recovery is about whether your existing accounts are billed correctly and whether the charges are set against the right figures. It happens whether or not you ever change supplier, and it does not depend on a renewal date.
