So this was from Sept to November 26th 2021
Electricity:
Unit price for me is 17.37p
Standing Charge: 20.94p per day
Electricity Total was: £95.88
Standard Charge was: £12.35
I was with Green energy, they went bust. Got moved to EDF who offered a better tarrif than Green and locked me in for 2 years. Bet they regret that now!
So from Sept to November I used in addition to the solar 552Kwh my total bill for that quarter was £95.88
My Gas was 410 Gas Units (4577kwH) at 3.132p
Standing charge was
24.9p per day
Gas total: £143.35 (though this was from Jun to November as they messed up the metre bills so 5/6 months instead of 3)
We use NEST to control the heat and it never goes above 16c during the day and about 20c from 6pm to 10pm. When people visit they say 'oh this is cold' but I'd rather have someone say that then pay £400 a month thats good pinball money!
I also NEVER have to heat the water with gas, the Solar inverter heats the immersion heater and I get boiling water every morning without fail. This cut down on the gas charge a fair bit.
I'll provide December bills when I get it but looking at December from my solar edge:
I pulled 360KwH from the grid. This is normal since Solar only provided me with 120KwH this month (of which I only consumed 60KwH) so this month will be a bigger bill, but expected since I was heating a garage conversion with an electric heater for long periods of the day.
We never leave lights on in rooms we aren't in. Dishwasher and Washing machines are cycled during the day to make use of the solar. PC's are turned OFF and not left running over night (not even Sleep mode).
Pin machines are only turned on when in use.
It helps the house is under 4 years old and insulated to high heaven, with modern appliances and lights to reduce electricity consumption.
My biggest advice on reducing those monster bills is get a smart metre and see whats gobbling up the juice. Solar is great but I'm on the old FiT payment scheme (which provides on average £100 a quarter) this pays off the Electricity for me. House is south facing so makes a big difference in what it collects. If I bothered to get a battery I think my Electricity pull from the grid would be zero.
