WaterSure capped water bill

Your water company (statutory scheme)

Phone / post / in person England, Wales only

Water and sewerage bill capped at the company's average metered bill

Cost: Free

Upcoming change: Reform legislated after the March 2026 consultation, due early 2027 (mandatory in England, voluntary in Wales): extends to households on a disability benefit with income under £25,745, caps at the lower of average metered/average bill, adds a single-occupier cap, removes the medical note requirement.

What you get

Your metered bill is capped at the average bill for your area however much water you use. Crohn's disease and ulcerative colitis are named as qualifying medical conditions.

Who qualifies

On a water meter (or an assessed charge where a meter cannot be fitted), a household member receiving a qualifying benefit (Universal Credit, Pension Credit, Housing Benefit, Income Support, income-based JSA/ESA and others), and either a named medical condition causing high water use or three or more children under 19 at home. Apply to your water company each year.

Evidence accepted

Proof of qualifying benefit
Medical practitioner's note (being dropped in the 2027 reform)

IMPORTANT TO NOTE One of the few household-bill schemes that names Crohn's disease and ulcerative colitis explicitly.
