My rates are:
electrictiy 13.115p per kWh
gas 3.098p per kWh
So if on my meter I've used say 40 units for gas how can I turn that into a £ figure? (40 x 3.098p doesn't seem to work, it would be much too low)
And for electricity if I used say 300 does 300 x 13.11p give me the actual cost? (this seems like it could be the right figure but I'd like to be sure)
Hope that makes sense, many thanks in advance
Quick final question is when submitting readings is there any way to change the date? Sometimes I take a reading but don't submit it the same day

There's some good news and some bad news on this.
The calorific value isn't quoted on the statement, but it can be worked out from the statement*, but that's only when you've had the statement which sort of defeats the object of the exercise.
The good news is that it doesn't vary by a huge amount so if you use an average value for your calculations (I'd suggest 39.4 MJ/m^3 or MegaJoules per cubic metre) it will be near enough to get you well within the ballpark.
Or as suggested, better still just use the calculator HERE which is close enough.
*You can work out what calorific value PP have used by the following
On your statement it says how many cubic metres youve used - call that C
On your statement it says how many kWh call that K
Calorific value = (K times 3.6) divided by (C times 1.02264)
so for example you used 40 Cu m. and your bill says they are charging you for 450 kWh
so the Calorific value used by PP is 39.6
(When I put the 40 into the website above it returned 447kWh)
