Gas heating vs Electric heating

Alnat1

The energy saving way is to have the heating off totally at night, no point heating the house while you're tucked up under a warm duvet.

Also, keep the thermostat in the living room if that's where you spend most time. Get TRVs fitted, turn them down/off in unused rooms and keep doors between room closed. Why heat a hallway at all if it's just somewhere you spend 5 seconds walking through.

For an electric heat pump you can assume a COP of 4 so divide the electricity unit price by that. At the current price cap of 28p, that's the equivalent of a gas price of 6.3p per kWh vs a 90% efficient boiler.

Add into this the guesstimated price of gas 15-16p and electricity 45-47p come October and the ratio may for the first time become 3:1 or lower between gas and elec for cost per kWh

I'd doubt that you'd get a COP of four. unless the heatpump is run at it's optimum the whole time, which it doesn't as it is contingent on the weather and the temperatures that you've got the heating set to. 

A heating system with a heatpump has to be deigned, set-up, commissioned and operated correctly to even get close to three, especially if it's everso cold outside.

A COP of three is much nearer the mark and a better number to use for guesstimating prices and consumption and IMO anything better would be a bonus
