Glos Guy, MrsW would use 1.5kW of electric commuting (less than 3 miles round trip), so we save that although working from home she’s probably using much of it running computer equipment etc. She would buy drinks at work but food she would take with her. So very little saved by not going to her workplace.
Our gas bill for the quarter to Christmas (heating and a gas hob) was £368. This quarter will be much more.
As Abercol says the govt tax allowance is £6 a week. I must check if she’s claimed it this year…
