Just recently moved into this house and it has a single phase watt hour meter, it is positioned just above the normal main switch box. To be honest I dont know if I had similar in my previous house. What is it? as in whats it for. and Every so often I see a red light flash on momentarily, what is that for?

Sounds rather like the electricity meter! You probably know what they are for ;-)
There will usually be a indication of the flash significance printed on it - say one flash every 100th kwh consumed. So basically the faster it flashes the more its costing.
Usually 1000th of a Kwh. Ie, it flashes once per watt hour.
Thanks for replies, wasnt sure if the light was a warning light of some kind.
Only that someone is dipping into your pocket on every flash ;-)
(just looked at mine - that is one flash per 1000th kwh as well)
Wouldn't it be simpler to say 1 wh per flash? :-)
It would, but I was indicating how it is marked.
With a *small* w ????
