North Norfolk here. Temp hasn't fallen below 14 at night over the last week or so. I hadn't reset the thermometer in a week or more so I don't know what the temp has got up over the last couple of days - it will be a fair bit lower than the 26 it shows.

Inside haven't been aware of the house heating (set at 18) coming on yet.

I think living room lights were switched on about 7:30pm today. One thing I have noticed is that even though it's not really a great distance, it stays light longer in N Wales where I lived before. When we talk to my brother who still lives that way, the difference seems to be somewhere around an hour, maybe a bit more.
