A calm afternoon with unbroken sunshine shining through the west facing windows between 3 and 5.30pm has resulted in not needing to give the house a one hour central heating boost this evening. Most unexpected ! .

18.2c in the hallway with temperatures ranging from 18.7c to 19.2c elsewhere around the house. Thick curtains now closed to trap it in.

Very pleased. 

17.3c - back door wide open    

18.4 C this morning and clear blue sky outside, so I'll squeeze out another day without heating

16.9c in the hallway when I got home from work. Leaden skies and driving rain outside.

Central heating switched on with the thermostat set to 18c.

An unusually large spread yesterday afternoon: 24 upstairs and 17 downstairs.

Overnight the heating came on and by the morning it was 19 up and 16 down.

Upon coming in this afternoon it was 21 up and 15.5 down, the heating came on as I opened the front door.

It's now 21 up and 16 down, the heating being set to 16.

18.3 C this morning.

The BBC news featured a couple who for medical reasons needed to keep their house warm. Life is going to be tough for them this winter, and I sympathise; but I'd sympathise more if the accompanying footage hadn't shown a completely open floor plan with no draught exclusion or doors shut etc to compartmentalise the warmest parts of the house.

Sadly modern house design seems to eschew rooms and hallways downstairs - nothing to do with it being a space-saving measure, I'm sure.

Individual rooms that you can heat separately will really come into their own this winter. I think there will be plenty of people with large, modern, open plan living room-cum dining area-cum kitchen who will be groaning this winter...

17.6c in the hallway this morning. A recovery.

19.7c outside. The doors are open trying to usher the 18c chill away from indoors. (There won't be many days I'll be able to do this now).

22.5c Indoors with the sunshine through the window.

Went up to 21C at lunch time when sun was warming up indoors, then as the sun leave the SE facing windows, the temps indoor drop to 19.5 and back to 20C with shutters closed, computer on, wife cooking so keeping indoors warm and heating free day.

Sunshine raised the internal temperature in the hallway to 19.3c with a general 19.7c to 20.2c around the house. After the recent chill it feels positively warm.

18.6c in the hallway this morning. The recovery continues.

A general 19.2 to 19.7 elsewhere.

No heating required.

A combination of a mild calm and cloudy night (outside low 13c) and yesterday afternoon sunshine has given things a nice boost.

Really hoping that the sun shines from 2pm today. If so 20c could be reached in the hallway with 21c elsewhere. We need the cloud to clear away for that though. 

21.5 C late evening yesterday; 20.2 this morning. I'm surprised that there was so little cooling even given that it was a mild night

Warming up after the rain. 22.0c Indoors.

I've had a "Tado" smart thermostat for a few years now. It has been fantastic. Once you set a temperature in remains there within less than half a degree with no fluctuations because it throttles back and just gives the amount of output as required. Also geolocates if you go more than a specified distance from your home and switches off when empty then pre heats when it knows you are back in a certain range. I wouldn't say it's saved a fortune, maybe 10% or so but the comfort level is way up. Plus the convenience of easy programming on phone app or PC makes life easy. Cost about £120 but I did install it myself.

23.0c.  Sunshine through the window

It's been between 16.5 and 17.5 downstairs for the past day and a half, no heating but getting close to the 16 threshold.

Upstairs it's generally been between 19 and 21; it's presently 21 up there with the sun shining in.

EDIT: A few hours later, with the setting sun shining in from the west, it's 23C up and 18C down.

Largely unbroken afternoon sunshine after 2pm, a light breeze, an outside temperature of 18c and a Sunday roast have worked their magic to give a hallway temperature of 21.0c with other rooms in the house in the range 21.5 to 22.5c.

With a few external warm days ahead and some nicely stored internal warmth I'm hopeful we now won't need to think about central heating for another 5 days or so. 

The heating came on briefly this morning as it dipped below 16C downstairs. It's a surprisingly cold night outside (7.8C) as of writing.

Much the same factors here and add in a cloudy night to give 22.5 C yesterday evening down to 20.3 C now
