Get it taken out ASAP.
I had a Yorkshire water metre installed 3 years back, it costs me more than the next door pays for there water rates. Next door is a large family and they always have the hose pipe on, I would not mind but me and my mrs hardly dare swithc the taps on.
You only have a year to have the metre taken out once installed!!!!
It is a myth it will save you money, you will not.
One important point that can be missed is that :-Standing Charges are the SAME for both metered and non-meterd supplies .
