I've recently moved into a new house and it is heated by Air Source Heat Pump. No gas whatsoever at the property. We've been quoted around £350 a month from the existing electricity supplier and I've been absolutely shocked at that, as it's about 3x more expensive than at my previous house (Gas Central Heating and elec combined price).
For context, the new house is 4-bed detached. The old house was 4-bed semi. New house slightly larger, but both have under-floor heating on the ground floor and radiators on upper floors.
How much do you pay? Is £350 pcm about right?
