Would definitely have the heating on now if it was connected up.
15.7c this morning in the house.

14.5 C, but it'll soon warm up with sun already risen; no need for a temporary burst of heat

16.8c for me. Suspect the sun will be get that to around 20c by mid to late afternoon if I don't have too many windows open.

Won't bother for a while but in a few weeks time I might use the woodburner just to nudge temps up a bit if it ends up staying persistently less than 18c. 

Sunshine in the lounge. 23.5c . Heaters Off. Cooking in the kitchen. The extractor fan will start up soon.

Day before yesterday light the cooker part on my new Rayburn for the first time. Soon warmed things up. Don't need the radiators on just yet.

22.5c with everything closed for the night.

Another sub-10C night and it's cooling down further.

19C upstairs, 17C downstairs. It was 23C upstairs when I went to bed last night.

14.6 C like yesterday

Down one degree with no heating on. 21.5c. 

18.8c with the back door wide open.  Just wearing a thin t-shirt.

18C and sunny outside, 17C downstairs and 21C upstairs... pretty pleasant, all in all!

Not much change into the afternoon, so as good a time as any to check the heating still works! 10 minutes later and indoor temperatures have gone up about 0.3C, and even though the heating's now off it'll probably rise a little bit more.

Good to know the heating's working for when it's needed, anyway!

Will check mine next month when it the time to turn on as I got all the radiators replaced last March which cost £2600 that time.  I am sure now is well over £3k on today prices.  20C in my brother house now.

23.7 C in , 19.1 out

In the end that 10-minute heating burst raised temperatures by a whole degree.

It's now 16C outside, 22C upstairs and 19C downstairs.

(And doing the maths, 10 minutes of using the 25kW gas boiler would have cost me 31p. Yikes!)

Sounds about right in terms of heating. 20 minutes of heating this morning raised the temperature of the house by just over 2 degrees (according to the Hive this equates to good heating efficiency).

I’m hoping it may not be needed after tomorrow morning for a few days a least, but as the outside temperature has been no higher than 13°C since Wednesday the heating has kicked in the last few days.

Between 18c and 20c seems to be the form both upstairs and downstairs this last week. This is down from 20c to 22c (on average) earlier in the month. I imagine that once the autumn winds pick up that things that the indoor temps will have a harder time staying at comfortable levels. 

I was actually surprised, considering it's windy outside, albeit the small temperature difference would have helped.

Then again, I'm still comparing it mentally to a couple of years ago. I had draughty 40-year-old windows (old aluminium double glazing) and a 20 year old boiler which wasn't very efficient. Both were replaced late last year. Last winter was much better as a result, plus I learned that boilers aren't meant to keep going on and off every few minutes all day long! 

(And as for temperatures not exceeding 13C for several days, in recent years that's early to mid November territory for here. The heating would definitely be coming on by then!)

For a hour last time I used in April and May cost around up to £2 excluding the nasty standing charges.  That time had no shutters so boiler have to burn more to reach 20C set on thermostat,  will find out next month when I close the shutters, turn on the heat at 22C and if rise quickly to 22C then might cost less than £2 and once turn off at 22C, and stay static to morning at 20C then heating would only need to be on 1 hour per day at dusk time and shutters closed.  that work out £2 per day for 1 hour heat.  

Rest get bonus warmth if there sun, TV, computers and oven will keep indoors warm.

As it is now tolerable to even contemplate a heating test I switched on the heating today and after many months of lack use and inevitable scale build-up in the valve, as per usual the two port valve on the heating circuit jammed half open and failed to operate the microswich to activate the boiler. After taking the valve cover off, and with a little gentle persuasion with a VDE screwdriver, it made the contact. A second try and it worked fine.

17.6 C but (psychologically ?) feels colder than yesterday's 14C

19 up, 17 down, much the same as the past few days here. 12C outside after an 11C low - and the wind has decreased a fair bit. If the sun appears today it should warm up quite quickly.
