You will need to post up some figures for comparison, where you are in the world, what system you have etc.etc..

Gas is very hard to compare, it really depends on isolation, type of house, month or year.
Anyway for a default home in the Netherlands with a default situation it's 1500 m3. Nibud says:
flat 1000
family house 1400
corner/end house 1650
duplex house 1750
detached house 2350
If you need to convert day/week/month measurements to year for an average year (average between 2001 en 2011) and situation (79% heating, 19% hot water, 2% cooking):
week / 7 = day (duh)
day * number of days in month = month (duh)
month * factor (see script below) = year
var gasFactor ={
January : 7.2,
Februari : 8.3,
March : 8.3,
April : 14.1,
May : 15.6,
June : 21.4,
July : 27.1,
August : 37.1,
September : 21.4,
October : 13.2,
November : 9.1,
December : 7.1,
};

As an example I've got a family home (tussenwoning for the Dutch). The last 24 hours I've used 6153 liters of gas. So that's 6.153m3 per day.
6.153 * 30 * 9.1 = 1680m3 per year

To bad there is no edit button, after looking through my code again I see that I'm wrong. My factor already contains the number of days per month. So it should be * 30.4 instead of number of days in month. Which would set the total in the example to 1700.
And just to show you how useless comparing gas numbers (especially day/week numbers) are; My real usage per year is 1050-1080m3. There actually is no such thing as an average home, it's just the average of all homes. The only thing that could really tell you something is comparing to a couple of neighbors as long as there situation is identical. The numbers above are something I've calculated from a lot of numbers and they give a much better representation then * 12, but the accuracy can still be off by 100% or in some special cases even more.

I'm using around 2500m³ of gaz for heating and warm water a year. It' a detached house.
I'm comparing my usage with that of SWORDS ... what a hugh diffrence.

2500m3 is not that much for an detached house. Here 83% cook on gas and the percentages are 79% for heating, 19% for hot water and 2% for cooking. So the average over-here for a detached house without cooking is 2350 * (1 - 0.83 * 0.02) = 2311. You would only be 7.5% above average here and once again that there is no such thing as an average home.
And please note that my house is very new (2008), very well isolated, has a new heating system, is 486 m3 and nicely tucked in between two other homes.
If you would provide some more info like rough location of the house (country and north/south/west/east or even better city), the m3 of the house and the exact numbers of the last 3 or 2 years I could do some more precise calculations if the average temperatures for your location can be found on the internet.

Hi swords, location is Antwerp. Nearest neighbour is 10 meters to both sides. Living volume (ground floor and 1st floor) around 550m³, build in 1976. Isolation far from good.
Heating is done during the weekend mostly with wood from our garden (hydrofoor-converter takes over central heating). Central heating (central part) is from 2006.
I don't think my figures are realy exagerated, but it's more the graph that wonders me.
