Gas
30/11/22 = 8601
23/12/22 = 8779
Total = 178 units = 1958 kWh = £196 = £8.15 per day
Estimate for December = £253
Government contribution = £67
Cost to us = £186
Electricity
Very stable monthly usage = £100 p/m
Grand total = £286
Monthly direct debit = £254 with £680 held on account by EDF, so I doubt we'll be stuck with any extra costs by the end of winter.
3 bed 1930's semi-detached
100m² floor plan
Solid walls with no insulation.
Double glazed - half new, half very old (but with new glazing units).
10cm loft insulation.
Gas central heating set to:
19°C overnight
20°C daytime
21°C evening
It's 3x what we were paying previously, but seems fairly reasonable compared to the 'media fear' and the crazy costs other people are posting.
