We’re getting regular readings from your smart meter but I can see there has been an increase lately- has any work been done at your property or new appliances installed etc?
It’s unusual for a meter to not be recording accurately, causes can be:
Particularly cold or mild seasonal weather leading to use of more or less energy than normal
Changes in circumstance (eg illness, new baby, working at home etc)
Faulty appliances using more energy than it should (a trace test would show this; which can be carried out by an electrician)
Changing types of appliance (ie moving from gas to electricity or vice versa)
If you believe that none of the above applies to you, you can try a little test on the meter.
All you need to do is to take a photo of your meter reading, turn the electricity off at the fuse box, and then take another photo at least 30 minutes later. The reading shouldn’t have changed over that period. If it has, there could be something wrong with your meter. You’d just need to send us both sets of photos so that we could have a look for you and take it from there.
Let us know how it goes!
