Since switching to three phase my consumption has rocketed to 25,000KWH per annum, despite no significant additional load.

adam spearing

We moved to three phase 3.5 years ago an anticipation of electric cars (which we don't have). 

Since then We have been consuming around 25,000KWH pa according to the meter. 

I've had a second meter fitted and it's validated these numbers. 

When I switch all the RCDs off it stops, so clearly it's my side of the RCDs. 

The house is around 10 years old with gas heating and gas cooking. We have low energy light bulbs. 

The overnight consumption seems to show we're using 4+KWH per hour when we're asleep. 

Load balancing was mentioned and I vaguely remember it from my degree but I don't believe that's it. 

Large donation to charity if you can help me work this one out

thanks in advance

    Thanks for the guidance !! Two updates

    I turned the MCBs off that feed a shed (freezer & Hot tub) and greenhouse (Heater) overnight and it dropped by 1/3 ! (36,000 KWH pa to 24,000 KWH pa) 

    I then turned everything off EXCEPT the house fridge, aga, boiler and dishwasher and it drop again to 16,000 KWH pa - but that ONLY running four items !???!?! 

    I now have an electrician with a clamp meter coming out on Friday to do the testing you've all suggested. I'll keep you posted 

    Really appreciate all this advise.

    Hello, Aga, Greenhouse Heater, and Hot Tub will all be big consumers especially at this time of year.  You can probably expect the greenhouse heater to be on 24/7 unless it is very high power,  Aga will depend on how well insulated and draughty your kitchen is.

    Out of interest did your old meter have a spinning disc?  These are generally very reliable but if they go past their certification date (which are not dealt with at all well these days) they can start to run slow if they have jewelled bearings.

    The old meter was installed in 2011 (when we built the house) so it wasn't that old. I've never kept my old elec statements and since NPower was absorbed into EoN I can't get an old statement from them. However the bill was only around £100 PCM before this Phase meter.

    'only £100 a month'? Astonished My own electric bill is only around £60 at the moment! But then I'm not running a hot tub in the garden... Wink
