The introduction of air testing in Scotland in Section 6 of the 2010 Scottish Building regs has resulted in a better build standard. Whereas previously gaps and unsealed openings which were out of sight could be ignored, the air test (or air pressure test/ air tightness test/ air leakage test as it's sometimes known) means that a minimum air tightness standard has to be achieved (10m3/h/m2). Excessive air leakage results in excessive energy costs.

Sounds obvious perhaps? But it's not usually the main loft - if your house has different sections of roof and you can't access everywhere from the loft hatch, chances are the guy putting in the insulation couldn't either!
