Well not the race card thing , but I think that in serious cases they get Trading Standards involved .
NICEIC will throw the book at you for misuse of their logo but I think thats about it . Local Building Inspectors rarely act against , say, Cowboy Builders , if ever . Its not within their remit .
Builders are still using unregistered sparks on .say, an extension , then at the end the customer can't get it signed off . All after the builder has been paid of course. LABC can't do anything , just won't sign the job off . Builder is laughing all the way to latest 4 X4 dealership .
