Fackinell, £20!!
Just to soothe you, our ~145sqm half-insulated solid brick house needed 29kWh of electric to run the heat pump yesterday, average outdoor temp of 1 degC, entire house at 21 degC 24 hours a day (heating is always on). Cost for this, including full 250L tank of hot water, was £4.60 on Tomato Lifestyle.
Who's installing your ASHP, and which one are you getting?
ectoplasmosis-
That’s pretty good considering you have solid walls!
our 80sqm 2 bed flat costs £160 PM for gas and electricity in a very cold month with most of the rooms at 21º-22º 8am-12pm and the bath full to the brim with piping hot water that’s too hot for me but not my partner.
We are both home most days, what can make a difference is the sun coming out even if it’s freezing outside that can warm the lounge up to 23º+ and mean the boiler isn’t firing up until late afternoon.
Have found an issue with some cold bridging on a concrete pillar that’s part of the external wall in a wardrobe that’s rammed full and not been opened, there’s been some condensation and a bit of mould on the clothes squeezed up against the uninsulated wall/pillar, i have some insulated plasterboard left over so i’ll do that section in the summer. there’s a concrete pillar in some room corners which i always knew would be a cold bridge after insulating the walls but it’s this one with no airflow in the cupboard that’s caused problems.
the flat is usually around 45-55% humidity and doesn’t get above 60% when washing is hanging up but a small Maeco de-humidifier might be on order.

@ectoplasmosis - making the switch to Tomato at start of Feb. On their "Lifestyle Tariff" with costs at:
1:00AM – 6:00AM = 5.004p/KW
9:30AM – 11:30AM = 13.374p/KW
8:30PM – 10:30PM = 13.374p/KW
Remaining hours of the day = 22.15p/KW
Daily Charge = 40.82p/day
With an ASHP being installed our electricity will obvs increase. But we're paying loads for Gas/Elec at peak hours with Octopus (yesterday combined Gas and Elec was ~£20 and this is with me constantly turning the heating off, much to my wife's frustration) and also have an oil tank we've needed to top up every quarter.
Interested to see costs over the next few months!
