My DH works from home and will only put the heating on when he's absolutely freezing, and then will normally only put it on for an hour to take the edge off. He works in a small room and wears a big fleece.
Otherwise our heating is on from around 6am until 8am, then 5pm until 9 pm, so 6 hours a day. With the extra hour or two a day when it's really cold, it can easily be 8 hours a day.
7 hours of heating a day, when you're home all day, doesn't seem that unreasonable really.
Our costs in November were £215 for the month and December so far (only 3 days recorded on the app) is £30, so £10 a day on average. November was obviously a lot warmer at the start of the month, but if December keeps on going the way it is, our bill will be c. £300.
Last winter, our worst, coldest, day was about £15 for the day, so would work out at about £450 for the month.
Luckily we've built up a massive credit on our account (over £800) from the increases last winter being combined with us reducing our usage. As a result Scottish Power reduced our DD this month to just £100.
Two things to do:
- check you're on the best tariff and your costs are based on actual and not estimated usage; and
- consider how you can reduce your usage. Rather than paying to heat the whole house during the day, would a small electric heater or heated blanket, just where you're working save you money? We bought new curtains last year, some cheap Ikea rugs and made sure we kept internal doors closed in the draughtiest rooms (hallway and downstairs loo particularly) and it made a massive difference to the heat retention.
