Thames Water financial support
How to check Thames Water’s current bill-reduction, WaterSure, payment and priority-service routes using the household’s actual water situation.
Last reviewed: 6 July 2026 · UK guidance
In brief
Water support can include a social tariff, WaterSure, payment plans, metering advice and priority services. Each uses different criteria, so ask Thames Water to check every relevant route.
Water debt should be addressed, but domestic supply cannot be disconnected for non-payment in the same way as energy. Do not ignore court or collection letters; seek advice and agree an affordable plan.
Check tariff and meter status
Confirm whether the property is metered, estimated or on an assessed charge. Ask how a meter, fixed assessment or social tariff would change the annual bill and whether the household can trial or review the option.
Check WaterSure separately
WaterSure has national conditions for eligible metered households with high essential use. Ask what benefit, household and medical evidence is required and how the bill cap is applied.
Address arrears and ongoing charges
Request an affordable arrangement based on income and essential spending. Ask whether a scheme reduces debt, current charges or both. Keep the annual bill and payment schedule.
Register support needs
Ask about Priority Services for accessible communication, meter help and incident support. Explain practical needs and update them after moving.
A Thames Water review request
Use to cover all routes in one contact.
Please review my Thames Water account for the current social tariff, WaterSure, metering or assessed-charge options, an affordable arrears plan and Priority Services. Confirm which route changes current charges, which affects debt, the evidence required and the annual bill in writing.
A practical checklist
- Confirm meter and annual charge.
- Check social tariff and WaterSure separately.
- Separate arrears from ongoing bill.
