Well, I was cooking tea on Sunday night and the oven went off. Tried the hob. No gas. Went and checked the boiler, central heating was off as well. Wonderful Checked the gas meter which is a new (one year old) smart meter from First Utility. I pressed the button to light the display only to be told my credit was off. Went through a sequence of button presses and the valve opened. Hey presto. Heating was back. Then, it went off in the middle of the night. I only knew about this as the minimum temperature alarm went off on my eight month old daughters room monitor It has since been off several times. I rang first utility (several tries) and apparently it's an issue with something coming loose within the meter which makes it think it's been tampered with. So, I'm now sat at home waiting for an engineer to turn up to replace the meter. Odds on him arriving?
