High gas usage

I've done a space test from last week with using hardly any gas, heating on for 2-3 hours for 5 of those days and 1 hour the other two day and the reading started on 39984 from one week ago and today is 40044, so 60 units have been used, using the bare minimum gas 

Our "worst" weeks in gas usage were when the OH was ill with covid, I left central heating on pretty much 24/7 this was end of Dec/beginning of Jan. We used about 400kwh per week then. That is about 35 units?

This was in a detached two bedroom bungalow, one bedroom unheated behind closed door, the sitting room vents fully open so full heating at about 21C, in the rest of the house vents half-closed (so in theory less heating was produced there, but tricky to calculate with warm air heating).

Edit: no baths here, just shower and only two of us (and when OH was ill he skipped his shower some days as was too poorly). Gas hob but minimal cooking.

As a gas CH user, I turned down the flow temperature on my boiler from 74C to 61C this year. I have smart meters so can see there was a reduction of 10-15% in gas usage, so that factor alone would only explain a small part the high usage.

There's more to this than just a quick adjustment or two. If the flow temp was set high, the rads would be too hot to touch. Are they?

Yes so my one week with the bare minimum gas being used has worked out at  671kwh and that with no one being home for most the week, gas being off for two days and one hour in the morning and one or two hours on the night

Does this help this is how i have the settings on the boiler, and no rad are not hot to touch as cant have them too hot with the kids about

Also I do not have smart meters so that's where the confusion is, as I don't understand how I could possibly use so much in such a small time space

212 kwh per day seems crazy, maybe on the cold weeks but not everyday for 60 days. What is the room thermostat set to? 


EDIT: 198.8  64 days

And now you can be an expert at gas rating your boiler and hob.

Room thermostat is on 20

As already mentioned by @Molerat earlier your meter shows that the average annual usage for the property is more than 20000KWh. (meter production date 2001 and 40045 m3 = almost 450,000 KWh in less than 22 years)

Its already at around 21,000 kwh with still 2 months to go, So it would mean the OP hasn't managed to cut down any use in this year.

What did the supplier say the annual usage is and the DD they wanted/set?


What is the energy certificate saying the usage is? And the grade, size of house?
