I've checked the readings and there correct.

I've checked with the boiler off and no leaks.

Also done a calculation from the bill to now and weve used a further 200 units. what i didnt vheck is if its imperial and they given us a metric reading. surely this must be the case.

The house is very old. what is the meter likely to read in. cubic feet? cubic yards weve still used a lot. but feet doesnt seem enough.
