Hello,

We have moved in into a new build flat in the end of October. Month later we received a normal, 60 pound bill for estimated use. Which was fine. Then on the 2nd of Feb, we were asked to enter our readings. And yesterday, we received our new bill - 670 pounds for 3900 kWh for 69 days! This is average of 57 kWh per day! I cannot understand how is this possible?

So, the flat is 2 bed with a living room. Everything here is electric. This is what I was able to calculate myself.

• Boiler (not on demand)- it says that it does up to 6kWh per night, but sometimes we turn it on for an extra hour. So lets say max 7kWh.
• 2 bedroom radiators - i think they are ~1kw each, and we have them for ~3h each a day, so max 6kWh
• Two other radiators are broken, and we have 750w electric heater in the living room, which if we have on for 8h, is max 6kWh.
• And then there are 2 bathroom tower rails, probably ~200w each. One is on for 24h a day another is for 12 hours, so both of them should be max 7kWh
• So in total we get max 26kWh for heating and water.

All that is left are lights, two computers, cooker, washing machine and a fridge. I cant see these taking 31kWh a day.

Can you please let me know if I am calculating something incorrectly? Maybe something is using electricity even more?

Could broken radiators use electricity even if not heating up?

Thank you for all your answers.


EDIT: Recalculated everything based on all meter readings, and everything is +- ok. Conclusion - use less of tower rail

Was going to say its keeping things on 24/7 does chew up the lekky even if you think it shouldn't. Used ot have my heating on 24/7 using about 20 units during the day but overnight it almost tripled meaning I was using about 70 units a day - real head scratching stuff.

What I am going to try is 16-amp PIRs set for a 15 minute delay so only the rooms getting used will be heated

I suspect your gas meter was not a new gas meter when it was fitted into your home in October last year.

In some cases, reconditioned meters are fitted (ie: used somewhere else before fitted at your home). Your suppliers are probably assuming that a new meter was fitted on a reading of 00000 when in fact the reading was a lot higher when it was fitted at your home.

On your initial estimated bill that you got in November, what was the start reading on that bill for the gas?
Does that match up (or nearly match up - the builders may have used a bit of gas before you moved in to your home) to what has been entered as the start reading on the sticker (or label) that should be attached to your gas meter?

I would also check the meter serial nuber on the meter to that which is on your bill.
In many cases, gas meters get mixed up on new build estates.
ie: the supplier may be billing you for gas meter that is really at another home on your road. This other house will probably then be having their bills based upon them having your gas meter (or yet another house on the estate).
This type of !!!!-up happens incredibly frequently in new build areas. Especially for gas meters.
