attic insulation and energy service check

hi,
been reading about this energy team from electric ireland and how they give the house a once over and then give their recommendations. has anyone used them and how did they find them?? i assume there will always be something that can be upgraded :pac: are there any other companies around the cork area who do something like this??

and i'm also wondering if there is something i can do about losing heat through the stairghe going up to the attic?? i assume that heat will go through it as its not insulated like the rest of the attic floor??

and lastly is i got some attic planks in woodies to put some stuff up there for storage. is this ok as its compacting some of the insulation (its not the insulation rolls, its more like the loose stuff)??

thanks!
