New Gas Meter Installed - Readings Now Double What They Were

[Gizmonster]

.... as above really.

Someone came out to check the gas meter after we informed our supplier that we could smell gas in the meter cupboard. It was found to have a very small leak and was replaced. My missus is very organised and has all the previous monthly meter readings going back a few years and for some reason the meter readings are now roughly double what they were for the same month last year. This has been going on for a few months now, so it wasn't just a one-off.

We have informed our energy supplier and they have reassured us that the new meter is probably not at fault. They've told us to perform a "creep test", which we have and the meter is not creeping. We only have a gas fire, which is rarely on, as the central heating is on a timer; a gas hob, which hardly gets used and our combi boiler. They are saying that one of these must be at fault. We have not increased our usage and nothing has altered in the house in any way whatsoever. Our energy supplier have said they'll replace it and have it sent away for testing; but if it comes back as not faulty, we'll be liable to pay the testing fee, which is just short of £200.

Anyone any idea how likely this new meter is likely to be faulty?? It just seems too much of a coincidence that as soon as the meter is replaced, the meter readings double :(

//// Wouldn't a reading of cubic feet (your old meter) have shown a higher reading than the new one which is in cubic metres? ////

..... that's that I thought as well, so I looked into it some more and 1 unit on the old meter equated to a usage of 100 cubic feet and 1 unit on the new meter equates to 1 cubic metre.
100 cubic feet = 2.83 cubic metres, so to compare both readings you need to multiply or divide each one by 2.83.
