To be honest the whole system is a joke whether it be FENSA or CERTASS, none of the inspections regard quality of install or survey they are only concerned that the window conforms to Document ‘L’, I am in the trade and I wouldn’t have the first idea where to get a window that didn’t comply with Doc L. They only inspect 1% of a company’s work so that could be once a year in
some cases.
‘Unovolo’ I can assure that a window too small is not easy to fit, it just ensure’s less ‘miss’measure’s, so you can get any ole Tom Dick or Harry to measure them and pay them bugger all to do it. A snug fitting window with no trims is the ideal but seeing as installer wages haven’t increased at all for the last TEN years us skilled tradesmen (and it should be classed as a trade) are getting out into other things. I feel sorry for future customers as there is no proper apprenticeship and believe you me (I’ve seen it with my own peepers) an unskilled ‘installer can do a serious damage to your little abode. If you’ve Not watched White Gold do so now it really happens and a follow up series on the fitting would be even better.
