Average gas consumption for winter quarter?

from 21st Sept to Jan 22nd we have used 11,802kwh costing £440.98. Although I'm not sure whether this is considered good or bad?

"Averages" don't necessarily apply to every case but my table suggests 62% from Oct-Jan (4 months) therefore a projection of 19,000 kWhrs per year. That is 15% above the "average" of 16,500. Of course probably a 4/5 bed house may well reasonably be above "average" (and you have cut back).

So basically, keep taking monthly readings. And make sure you are aware of any assumptions your supplier is making regarding projected consumption. BTW that is almost "impossible" to extract but good grounds for a complaint if they don't/won't say.

Thank you. I can't use my consumption from last year as we moved house in the summer but will use this for future reference. Thanks.

Apologies, I just noticed a slight error in my post. The 48% is right for the Dec-Feb period you asked for but I typed Dec-Jan by mistake.

I have a large four story house built in 1820, i.e not insulated at all.

I have used 5,533.

My consumption this year is easily less than half of the previous 2 cold winters.

OH!!!! Based on this, it would appear mine is rather high. How do you have your CH set? How many rads? Do you have every rad on? I'm going really wrong somewhere.

I have 20 rads and three towel rails. I do not use any timer this year because it has been so mild, but if it was like last year I would have. So first off over the summer I went draught hunting and then this year for the first time I used the temporary "cling flim" double glazing because sash windows are a disaster area for draughts and this has helped immensely.

I just turn the heating on when it feels cold and only use the towel rails and the radiators on the floor I am in plus if the CH is on in the evening then I will heat the bedrooms. Then when the rooms are up to temp I turn the CH off, I find that the latent heat in the radiators keeps the room warm until I go to bed and the house is still at an acceptable temperature when I get up so I do not turn the CH on in the morning.

Also I used to find that when the weather was mild that having the boiler temp set to high meant that the rooms over heated (I have TRV's) so in mild weather I set the CH temp on the boiler to a low level and when it is freezing I set the boiler temp to max to get the house to temp as quick as poss when I get in.

So I reckon that weeldays my CH is on for 2 hours and at weekends about 4 per day.

Also I may be a bit unique because I have cast iron radiators so they work differently to normal modern rads as they hold a lot of heat and release it slowly. hence getting the house to temp and turning the CH off becase the large cast iron rads stay hot/warm for at least and hour or two.

Hope that helps and before I started to econimise I used to burn at least 30Kwh of gas per year.

Why have you got 'no insulation'? You can still put the full 270mm of loft insulation in an 1820's house. That is one of the main zones of heat loss.

another thing to do is to use the imeasure website to track your useage. It now has a feature that if you have past history it will calculate what your gas consumption would have been for the week based on past history and compares with your actual consumption. This is how I know that putting in the cling film has reduced my gas consumption by 150 to 200Kwh per week. Which is a lot over the 6 months of CH usage per year.

Attic bedrooms, no loft.

Why not celotex or similar foil/dense boards attached to roof timbers in loft rooms?
