My Ideal boilers started using 2-3kwh of gas overnight.

I had smart meters fitted in feb. No gas was used overnight till about two weeks ago.

The meter display hasn’t moved.

You need @Pigletjohn or @Johnd

if the meter hasn't moved, why do you say you are using gas?

Have you got a hot-water cylinder? Or a gas cooker?

The meter display hasn’t moved. It’s portable.

I have a hw tank and ch, neither are on overnight & the stat is programmed to off all day. I did that when the weather started to get warm.

do you mean the meter display hasn't changed?

So what is telling you you used gas?

If you don't need it for cooking, turn the gas of at the meter and see if it still moves.

off at the meter

How do you know you are using gas if the meter hasn't moved? I don't understand.

I think the OP means that the meter hasn't physically moved, from one place to another.

Gas leak?

Faulty meter?
