A quick google search shows 2 fridges do not use 16kwh a day. 25kwh a day total for the household is not impossible but would require electric heating running all day at a very high level. Normal appliances which are not heaters would never run at that rate. If you offer to pay £50 SP will install a check meter which would reveal your real consumption so it’s would be a good investment If they find errors they would refund the £50. You should get a big refund. Something is definitely wrong with your meter set up both before and after the smart installation.
Victoria, in my reply I meant that 2 fridges using 15 kw a day is impossible. Fridges cut in and out and don’t run continuously at their rated power, but a fridge motor is never rated at 7kw, that is impossible. Expensive items could include electric showers, 6kw and tumble driers 3 kw and washing machines 2 Kw also fires can be 2 kw and are expensive to run because they run continuously. TV and lighting is fairly trivial. Stick at it and get to the root of the problem. Keep us all posted. Thanks.
I've just spoken to SP to ask for a check meter but apparently because of the kind of smart meter I have got they can't put a check meter in place!! They are also still adament that the our 2 fridges and 1 freezer (all A+ rated) are using 14.4 watts per day and that it is perfectly reasonable for our usage to have almost trippled in the space of a year. We have now reached 'deadlock situation' which means they will give me £60 to leave as a good will gesture - £60??!!!!! Tp be honest even if they offered me more I'm not sure I would take it as it is now a matter of principle.
I feel that I have no choice but to take it to the ombudsman to see if I can get this issue resolved. I'll keep updating on here in case anyone else is finding this useful.....
