You either need to use a FENSA (FENSTRA?) registered double glazing firm, or else you or someone else needs to satisfy the BCO that the neccessary U values will be achieved.
You can't decide what kind of spec window /glazing unit to have until you know what U value you need to achieve, and this will involve calculations.
