British Healthcare Trades Association (BHTA)

Check whether a walk-in bath company belongs to the industry trade association before you buy.

The BHTA is a not-for-profit trade association that describes itself as working to improve industry standards and consumer protection, with more than 400 accredited members bound by its Code of Practice. Members include bathing, mobility and stairlift companies. Its free "Find a member" search is a sensible first stop before you invite any company into your home — membership is not a guarantee, but it does give you a route to complain if things go wrong.
