No really gend up on this.
Can a person who is paying more water rates (than the same house across the
road with two bedrooms) be able to get a rateable value assesment on their
property?

friend is paying £21.00 a month, whilst tenant across the road is paying
£15.50 for the same circumstances housewise, except friends house is in
poorer condition than the one across the road.

The ofwat site below says...

Can I appeal if I think my rateable value is too high?

No!

Surely this cant be the case when a house the same cubic size and 2
bedrooms.
