Yesterday: gas 100kwh (£10.24), electric 2kwh (64p) + standing charges-> £11.62
Gas slightly higher than usual because of turning the CH off til midnight the day before (only heated the front room), then getting the flat - esp my bedroom- back up to 18, which took about 3 hours.
Today so far I've used 22kwh from midnight to 10:30am, so £2.25 to have the heating set to 18 overnight. Ele so far is 0.5kwh/17p
