UK High energy usage!

[RapsterUK]

Hi all, trying to work out what's using so much electricity in our house. It's an average 3 bedroom mid terrace house, 2 adults and 3 young kids. Our electric bills have been very high recently and state we're using an average of 35kWh per day! From looking online, the average is 8-10 a day. I've bought a usage monitor to try and see what the hell is going on. Our heating is warm air heating, so all gas apart from the control unit. Out water is heated by an immersion heater with thermostat, so probably not the cheapest method, but I've already eliminated this by turning it of overnight and still seeing over 3KWh of usage between midnight and 6am! With no major appliances on (cooker, tumble dryer or immersion heater) I'm seeing around 600-700 watts of usage, does that sound high? If I can't find and appliance that's causing it, could it be down to an electrical fault somewhere?

Do you have any electric underfloor heating? In the bathroom for instance?
I've known a number of 'wrong high bills' which turned out to be an overlooked floor heating element left switched on. It's almost certainly not an electrical fault, a leakage of the magnitude to noticeably increase bills would quickly manifest itself either in tripping circuit breakers or a fire!

I have heard of a case of an earth fault in a outside shed, mixed with a TT installation caused a couple of amps to go to earth....

Presumably if it was TT there was either no RCD or it was inoperative?

Voltage operated trip that was inopperattive.

Bit off track but started a refurb on a semi and isolated all circuits to strip out, 2 days later the neighbour complained they'd lost their immersion heater since we started.
Must have been like it for years!

You'd think the neighbour would have kept their mouth shut!
