If you’re a Thames Water customer living in a flat without a water meter, there’s a little-known way to cut down your water bill—potentially saving you £1,000 to £2,000 over time. This under-the-radar money-saving opportunity has been around for over a decade but remains relatively unheard of, leaving many residents unknowingly paying more than they should.
The Secret to Lowering Your Water Bill
Thames Water offers an Assessed Household Charges scheme for homes where a water meter cannot physically be installed—a situation common in converted flats where complex plumbing layouts make fitting a meter impossible.
Instead of charging based on a home’s rateable value—an outdated system often tied to old council tax banding—Thames Water will switch these households to an assessed value bill, which calculates charges based on the average water use for similar-sized homes.
For example:
- Standard Rateable Value Bill: £600/year
- Assessed Value Bill: £400/year
- Single Occupier Tariff: £300/year
Over five years, a single occupant could save £1,500—money that would otherwise go down the drain.
How to Apply
- Check Eligibility: Visit the Thames Water Assessed Household Charges page to review criteria.
- Contact Thames Water: Call customer services and request an assessment for switching to assessed value billing.
- Apply for the Single Occupier Tariff: If you live alone, ask about this extra discount.
- Monitor Your Bills: After the switch, review your statements to ensure the lower rates have been applied.
