Need new central heating and electrics and the eco websites are too technical for me!

Its an old house with no CH and old electrics. As we are starting form new would like some energy saving/efficient thing but dont know where to start.

Any pointers?

Am no expert at all but I did find these people on my travels

We need to update our heating and are re-wiring and I thought they sounded like they might be a useful source of advice.
