How it works
Four steps, one signature, six years of bills checked.
We do the audit. We write the supplier. You sign one form. If anything comes back, we take 30%. If nothing does, you owe nothing.
Send us a recent bill
One quarterly invoice is enough to start. PDF, photo, or screenshot. We use it to identify your supplier, meter reference, and current tariff.
⌛ ~3 minutesWe audit six years of charges
We pull six years of billing history from your supplier (with your authorisation, one form). Then we go line by line: surface water drainage, estimated reads, trade effluent tiers, standing charges, VAT.
⌛ 2–3 weeksWe submit the claim
If there's a case, we write the supplier and submit the claim on your behalf. We handle the back-and-forth, including any pushback.
⌛ 4–12 weeksRefund lands in your account
Suppliers refund directly to you. Once it's in, we invoice 30% of what was recovered. If nothing was recovered, no invoice.
⌛ 60–90 daysWhat we actually look for
The audit checklist, in plain English.
Surface water drainage
Most common single finding
Surface water drainage
Charged on the roof and hard-standing area of your site. If that water drains to soakaways, fields, ponds, or any non-sewer route, the charge doesn't apply. We pull aerial imagery, drainage drawings, and on-site checks if needed.
Estimated meter reads
Almost universal
Estimated meter reads
Suppliers default to estimates when they can't get a read. Estimates compound, sometimes for years, and almost always overstate usage. We rebase the full six-year window against actual reads.
Trade effluent classification
Hospitality & manufacturing
Trade effluent classification
Trade effluent tiers band by chemical oxygen demand, biological oxygen demand, and total volume. Kitchens, laundries, and light industrial often sit one tier too high. Independent COD/BOD testing typically pays for itself when reclassification follows.
VAT and standing charges
Multi-site sites
VAT and standing charges
Disconnected meters that still attract standing charges. VAT applied to qualifying activities (education, charities, partial business use) where it shouldn't be. Quietly cumulative: small per-quarter, large over six years.

Worth three minutes to find out.
Drop a bill in, and we'll come back with an indicative number. Nothing to sign at this stage.
