Actual or estimated?
Compare the bill reading with the meter today. Photograph the meter with the date visible if possible.
Step 1
Check what changed before you complain.
A high water bill can be caused by a real use change, an estimate, a leak, a meter issue, wastewater charges, or a support scheme that has not been applied.

First checks
The strongest bill checks are usually simple.
Wrong meter?
In flats or converted homes, check whether the meter serial number on the bill matches the meter serving your home.
Leak test
Turn off taps and appliances, then check whether the meter still moves. Keep times and photos.
Surface water
If rainwater does not drain to the public sewer, ask about a surface water drainage rebate.
