I've been keeping a spreadsheet of my monthly Gas and Electricity usage for a couple of years, so I know my usage fairly well (sad I know, but lucky in this instance).
I had a Smart Meter fitted 2pm 4th Jan and checking the last 14.5 days (to 11pm on the 18th) my average daily usage has been 89kWh (total 1293kWh)
Looking at comparable periods in 2023 and 2022.
Dec 2022 average daily usage was 68kWh (Monthly total 2120kWh)
Jan 2023 average daily usage was 61kWh (Monthly total 1898kWh)
Dec 2023 average daily usage was 64kWh (Monthly total 1987kWh)
Looking at the first 3.5 days of January 2024 before the Smart Meter was fitted, I used 189kWh or roughly 54KWh per day.
We haven't changed any way we do things like times or temp. etc, they are all the same. I would expect Dec average to be higher as we turn it up for Christmas when my Mum stays here! Dec 2022 had a really cold week in it as well. I'm Norwich way, although it is a little colder now, we haven't had any snow where we are, and it's been consistently high each day since the fitment date.
I can't see how we are suddenly using near on 50% more Gas since 4th Jan then we did in Dec 2022, Jan 2023 or Dec 2023, which should be comparable months.
Called EON as either the old Gas Meter was under reading or the new one is over reading but call center guy tried to fob me off but unfortunately I was more technical than him, so waiting on a checkup and email response next week.
My only other thought is if the Smart Meter is interfering with the wireless Honeywell thermostat which is either stopping it from turning the heating off or possibly turning it on when it shouldn't.
We have the thermostat at 19C already and wishing I hadn't of finally swapped to the Smart Meter as it's going to cost £100's more then the old meter for the same setup.
So I was just wondering if anyone else has seen the same issue (possibly no-one else as anal as me at keeping a monthly log of usage though!)
Note: Electricity is coming out as expected from my usage history (I'm fairly consistent with that at around 300-330kWh per month).
