Have you put your heating on yet?

So we've come to the end of the test of having the heating on all day vs 2 daily heat cycles.
Between 27 November and 27 December we averaged 46KW/h per day gas use.
Between 28 December and 19 January we averaged 86KW/h per day gas use.
We made a few mistakes, first not realising the temperature was set to 21 and not 19 on the thermostat for the middle part of the day where it would usually be off. It's also been super cold compared to the November/December period.
We were £150 in credit which has basically been eaten by this test but it has been nice being warm all day and not getting the shivers at 2PM counting down until 3.45 when the heat would come back on!!
Electric is £1 per day more expensive also.
If you aren't taking the wweather into account and your gas usage includes the HW element it's tricky doing comparisons but just for fun I took your usages and used my HDDBetween 27 November and 27 December we averaged 46KW/h per day gas use.
Between 28 December and 19 January we averaged 86KW/h per day gas use.

You are certainly right in your statement - you used a lot more gas but your HDD may well be very different to mine depending on where in the UK you are
Below is my Usage data (Not including HW) for the same period

Missed this question
4 bed, fairly poorly insulated detached house. UFH heating all downstairs, rads in all bedrooms/two bathrooms upstairs.
£300 per month DD. So far my highest bill has been £478 this winter. Sadly I'm now becoming used to less than £500 a month being "ok"!
Ouch!!!! Is that bill just for Gas or both Gas and Electric?4 bed, fairly poorly insulated detached house. UFH heating all downstairs, rads in all bedrooms/two bathrooms upstairs.
£300 per month DD. So far my highest bill has been £478 this winter. Sadly I'm now becoming used to less than £500 a month being "ok"!
For Gas and Electric (Including SC and VAT)
Nov 23 Bill was £138.59
Dec 23 Bill was £206.14
Jan 24 I'm projecting to be £240

Average HDD (15.5):
Nov - Dec was 7.9
Dec - Jan was 10.8.
So that explains some extra use but not 100% more use. Unless Im wrong. I do need to read more about HDD though and how to use the data properly.

Our figures do include hot water. It's usually the same week on week. Showers each in the morning before work, shower after the gym before bed. Very consistent. Tuesdays & Thursdays is one shower a day each + maybe an extra for the wife if she wants to wash her hair. Weekends are usually 1 shower a day. It's usually some variation of that schedule, some days might get switched around but the use is basically the same.
OK then you can take off a daily allowance for HW and get a more accurate kW/HDD figure quite easilyashleyman said:

No you are quite right in that statement - increased usage but not 100% more like your original post suggested - shows the value of HDD data in compensating for the weatherNov - Dec was 7.9

If you have some historical gas usage data (By month would ideal) that HDD website has a regression tool which you can upload your historical usage by month and it will then run a calculation to determine the best base temp to use (rather than the default 15.5)When I ran that process it came back with 16.5 as the most representative of the point at which I need to run the CH and I've used that ever since
If you make changes to the property that reduce the energy usage you can always re-run the regression tool to see if your base temp has changed.
Try it - if you get stuck shout and I'm sure either I can help (or TMIAD will probably chip in to help)

E.on are now offering a 12m fix at 24.7p/kWh. Not sure how that compares to the next price cap review, but it looks attractive to me.
It's above where Cornwall Insights are predicting for the rest of the year. Foes insulate you from any shocks that might come, particularly form the ME, but so far that hasn't had much impact.I'm in NI and my provider discounted 7% from November and just in the news today, a further price cut of 6.3% from 1st March. NIce.
Not that that would interest anyone on here, but as part of that article, it talked about GB prices as well, and there is expectation that a 16% price cut is coming to GB, and expected confirmation of that is next month, when it sets the price cap for Q2.
Good news all around.
Ball park, my bill will be moving to 18p night, 28p day, 9p daily charge come March.

Just as I heard today on the radio LBC , an expert on energy predicting big cost increases to fuel, gas and electricity. I hope you are right . I had assumed it would all start to go up again now due to red sea issues, tanker on fire there tonight . Let's hope the fellow I heard today was a twit. There are enough of them on the radio after all.Not that that would interest anyone on here, but as part of that article, it talked about GB prices as well, and there is expectation that a 16% price cut is coming to GB, and expected confirmation of that is next month, when it sets the price cap for Q2.

This has bugged me for a while but I sent meter reads off today. They always send the typical email saying they got the reads. And ours from E.on says this:
“ Thanks for sending us your meter readings. We'll run a couple of checks to make sure they're in line with what we're expecting and email you an up to date energy bill in the next couple of days.”
You’re going to run some checks. What checks. Why don’t you just believe they are my readings. Am I a criminal? Irks me more than it should.

In case you've made an error which would result in your bill being £10,000 for the month.“ Thanks for sending us your meter readings. We'll run a couple of checks to make sure they're in line with what we're expecting and email you an up to date energy bill in the next couple of days.”

Maybe they have really really slow computers that take an age to compare numbers. It’s pathetic. I assume they run batch jobs every night that generate bills. “ Thanks for sending us your meter readings.

In answer to the "what's your DD" question:
4 bed detached in the Thames Valley, built 1971. Double glazed, loft insulated (could probably be thicker), cavity walls insulated. Ancient, heat only, gas boiler, kitchen appliances all electric. EV charged exclusively at home, does about 150 miles a week on average. One thermostat in the house - set to 20.5c, all rads (15 I think?) on full, heating on 24 hours a day roughly early November to April. 2 adults WFH full time, one teenager in residence, one teenager during University holidays. Although the thermostat says 20.5, true temp around the house is 19c downstairs and 17c upstairs consistently, according to a cheap digital thermometer from IKEA. I'm comfortable with that, Mrs CD spends most of the day under a blanket grumbling, daughter occasionally complains, I then point out to her she's wearing shorts and a crop top, so get dressed or shut up.
I'm on Agile, and pay a DD of £192 a month. I'm £100 in credit at the moment, will be going into debit at the end of this month. Last year I recovered from a debit position by about July, I'm expecting to do that a bit earlier this year as I think I'm paying a bit too much - but not enough to worry overly.
Quick update on this one in case anyone finds it useful, attached is my energy bill for January, on Agile. It's about £100 down on last January's bill, which is nice. It's still a bit painful of course, but I think using Agile has helped mitigate the worst of it. my account balance will be £-81 going into February, which supports my thinking that I'm overpaying a bit at the moment, and if prices go down further this year I can think about reducing my DD amount.4 bed detached in the Thames Valley, built 1971.

So far 1274kWh gas
300kWh electric
Can't see costs as octopus isn't showing the usage
But my usage has been a bit high recently in comparison to the HDD figure as it jumped up quite a bit during the day and it just doesn't react fast enough
