Heating stays off in my house between March and October. The main exception was April 2012 where I left it on due to it being -5C most nights. I'm hot bloodied and the only time I feel cold at this time of the year is first thing in the morning out of the shower. I'll just give one of those £20 Argos foot heaters a quick 5-minute blast to help dry me out. I know electric heaters aren't as efficient, but it's definitely better running that for 5 minutes localised on me than turning the whole house heating on. I'm not wearing coats yet, just a brolly if it rains.
