Trying to calculate cost of energy use - just heating?

Last month I took some before & after photos of the central heating being on to a) see what it cost and b) while wood is free it's a no brainer, but as we may have to start paying for it it'll then become a question of central heating or fire. I just never got round to asking about the cost until now...
So once I got home, the gas meter read:
22922|49|1 m3
With the first 5 digits in black, the next 2 in red & the end one turning.
About to go to bed & turn the heating off & took a picture of the meter reading:
22925|26|0
10.327p kw/h
November's calorific value: 40
I want to check I've worked it out right...
2.769m3
2.769 x 40 x 1.02264 (correction factor) / 3.6 * 0.10327 (rate /kwh)
=3.2492
=£3.25
Or have I messed up somewhere? If so could someone kindly point me in the right direction please?
