Cleaning is the broadest trade in the UK. Two completely different trust stacks for domestic and commercial.
BICSc (the British Institute of Cleaning Science, founded 1961) has 45,000+ corporate, individual, and accredited training members. It's the closest thing to a UK cleaning industry standard, but recognition skews commercial.
For domestic, customers care about: DBS checks, insurance figures, vetted staff, key-handover policies, and reviews. For commercial, BICSc, ISO 9001, CHAS, and contract-specific compliance matter much more. We build whichever stack matches your business. Most cleaners try to look like both and end up convincing neither.
