Bill validation

It depends on the contract terms and the limitation rules that apply to the supply. Where an error is confirmed, we set out in writing the period we believe is recoverable before any claim is raised, so you can see the reasoning rather than take it on trust.

A recent full invoice for each meter starts the check. With a signed letter of authority we can request contracts, statements and billing records from the supplier directly, so gaps in what you hold do not stop the work.

No. Each invoice comes back marked as validated for payment or held with a stated reason. You approve payment throughout; we never do.

The line is raised with the supplier as a formal query, with the contract clause and the figures behind it. The query, the response and the outcome are recorded on the account file, and a confirmed overcharge is pursued to a credit or repayment, which is recorded when it lands.

No. The first check across your invoices costs nothing: you see what reconciles against the contract and what does not before any fee is discussed. Ongoing validation, and any recovery work, is quoted in writing and agreed before it begins.

Yes. The same line-by-line method applies to water and the other utility invoices held under the letter of authority, read against the rates and terms that apply to each supply.
