The Tile Association, Pro Tile Fixers Association or None?
We have The Tile Association and now probably a Professional Tile Fixers Association.... but how many of you pay to sign up for the services they provide?
You can join something like the Federation of Small Businesses if you're after that sort of benefit. (cheaper banking, good tax support on inspection, decent insurances and free advice lines etc etc etc).
If your good at your job you shouldn't need any of this, how many times have you been asked, if you have qualifications or you belong to any trade organisation, i never have.
