Energy rating on your house (for HIPS Packs)

[Nosha123]

Has anyone here ever had an energy rating done for their house for the HIPS packs... I am curious as I have just had one done by NHBC for our new build house and wondered if compared to older houses whether ours is generally a good rating or not... We have fitted some eco stuff to the house - which I am sure has helped.
We are in the Energy Efficiency Rating C bracket.. with A being the best and G being the worst.
I would imagine that A is pretty un-achievable unless you use 100% renewable energy sources etc.
Can anyone tell me their rating and a bit about their property?
Thanks in advance

D is regarded as the average for an older house - whatever that means. Mine is C - same as yours. Timberframed new build. Would be B if I had an oil-condensing boiler fitted - chose not to because they were unreliable at the time (not a choice now, and the reliability has improved as manufacturers have learnt more about the technology).
I don't see how use of renewable materials or energy sources comes into it - there's tonnes of un-green concrete in my foundations. These ratings are about the ability of the building to stop the heat getting out plus the efficiency by which gas or oil-fired boilers convert fuel into heat. Its nothing to do with whether 2000 sheep lost their summer coats to keep a few humans warm.
