## In short

A meter often saves money for small households in large homes — couples in four-bedroom houses frequently cut bills 30%–50%. Large families with high use may pay more metered than on unmetered rateable value charges. Use your company's calculator before switching.

Water companies in England and Wales must fit meters free on request. Many let you switch back within 12–24 months if bills rise.

Unmetered bills use historic rateable values unrelated to current occupancy — unfair when few people use many bedrooms.

Assessed charges apply where metering is impractical — still worth reviewing if occupancy changed.
