Gas bill/ boiler/rad temp???

Yes I know 65 isn't high enough to heat the living room but even at 72 it doesn't seem to.

That's why I said 'the maximum'.

Look at it this way: if you're not going to use the highest setting in the coldest winter for years, when on earth are you going to use it??

9,928kWh over the 3 winter months is not that high, you can easily use 80% of your annual consumption in the coldest 3 month period. But I don't follow your figs, as if you have been in the property from late summer, then you should be able to work out your consumption from arrival date to 24/11/10.
Your heating will probably have been on for all of the 24/11/10 to 22/2/11 period, so you can't pro-rata you annual consumption from that quarter alone. Adding the autumn quarter (8/10 to 11/10) will give a much more realistic annual figure.

Ok sorry well the main question was about my winter usage but guess it may not be just the heating we are using a lot of gas on. Best figure I have is below

Average used from 16/09/10 to 24/11/10 was 52 kwh's a day.

Which over 70 days is about another 3,640kWh. So 13,568kWh between Sept and Feb. So I'm guessing your annual consumption is in the region of 20,000kWh? Which is not high for a large property heated to 21C for 14.5 hours a day-around £800 a year.

Ok fair enough just seems high to me as coming from a two bed house we were only paying about £35 a month and now around £55 and BG keep increasing this which by my cals is rightly so to maybe around £60-£65 really.

But anymore info on the water temp of the bolier would b great once it becomes a little milder and we find the living room heating up correctly I would like to know the most efficient temp the water should be at.

Here's another vote for "that's not expensive"... and I'm a miser over my heating!

Hi slacky555.First thing i would check is that the boiler is sized to the system.Many boilers are range rated which means they can be adjusted for lower or higher output.Boilers years ago were always oversized but this often caused the boiler to continuously switch on and off as it could not disipate the heat.Newer boiler are sized to the system and often run more constant basically chasing to heat up.As yours is a combi boiler the idea is to raise the incoming cold water by a certain number of degrees which means during the colder spell it may struggle to raise the water temp to your required level...as the weather improves and the cold water inlet rises you will find it will probably reach the required temp.Heating systems are designed at a temp of i beleive 82 degrees which is why your rads never reach temp.If the boiler is set correct it should reach a temp which allows the thermostatic rad valves to operate which when working correctly should save you about 15% in fuel.Once all operating reduce the room thermostat by one degree which believe it or not will save you 10% of your fuel (reducing by two will not save 20% as the calculation does not work like that ! ).So my advice is call in a boiler engineer just to check what the boiler is set to...hope that helps and dosen`t confuse !
