/ What we audit
Six places your water bill is probably wrong.
Surface water drainage audit
Most commercial properties are billed for surface water drainage that never reaches the public sewer — soakaways, balancing ponds, private drainage and septic tanks. We map your site and reclaim every overcharged pound, backdated up to 6 years.
Meter sizing & accuracy
Oversized meters massively inflate standing charges. We test meter accuracy, downsize where appropriate and recover the difference from the wholesaler.
Trade effluent (Mogden) review
Food, brewery, laundry and manufacturing sites are billed under the Mogden formula. We audit COD, suspended solids and volume readings — formula errors regularly hide 20%+ overpayments.
Multi-site retailer switching
Since deregulation in April 2017, all UK business water customers can switch supplier. We aggregate every site under one retailer with one invoice and a volume discount.
Leak allowance claims
Hidden underground leaks rack up huge bills. We submit leak allowance claims to the wholesaler and recover the consumption you never used.
Free historic bill review
Send us 12 months of water bills and we'll spot every line of overcharge — surface water, highway drainage, void periods, tariff misclassification and supply pipe ownership errors.
/ FAQ
Business water — frequently asked
Can I switch my business water supplier in the UK?
+
Yes. Since 1 April 2017 every business, charity and public-sector organisation in England can choose its water retailer. Scottish businesses have been able to switch since 2008. The wholesaler (Thames, Severn Trent, Anglian, etc.) still owns the pipes — only the retail billing layer changes, so service is identical.
What is surface water drainage and why might I be wrongly charged?
+
Surface water drainage is the rainwater that runs off your roof, car park and yard into the public sewer. If your site drains to a soakaway, watercourse, private system or septic tank — none of that water enters the public sewer, so the charge is wrong. Refunds can be backdated up to 6 years and average £1,500–£25,000 per site.
How far back can I reclaim overpaid water charges?
+
The Limitation Act allows recovery of overpayments up to 6 years from the date of error. We've recovered single refunds over £180,000 for multi-site retailers and £5,000+ refunds for individual SME premises.
What does a water audit cost?
+
Nothing upfront. Our audit and refund recovery is typically 30–40% of the refund and first-year saving. If we don't find money, you pay nothing.
Do you handle Mogden formula trade effluent?
+
Yes. We specialise in Mogden audits for breweries, dairies, food processors, laundries, abattoirs, car washes and chemical sites — checking COD, suspended solids, sampling frequency and reception/treatment/volume charges. Errors are common and the savings substantial.
Will switching disrupt my water supply?
+
No. The physical supply is unchanged — same pipes, same wholesaler, same water quality. You simply receive your bill from a different retailer at a better rate.
