Specialist guides
Commercial Cleaning Guides
The rules behind the work, written for the person who has to buy it. Each guide names the regulation, standard or statutory guidance that applies, sets out what a compliant job and report look like, and ends with the sources so you can check it yourself.
Fire, food and air
Kitchens and ventilation.
Kitchen extract is where cleaning meets fire law and insurance. These four guides separate the kitchen deep clean from the TR19 Grease duct clean and the TR19 Air ventilation clean, and set the intervals for each.

Buildings and sectors.
What changes when the building is an office, a surgery, a school, a fit-out or a warehouse. Each guide names the regulation or statutory guidance that applies and turns it into a specification.

Start with the guide for your building, then take its checklist into the quote. A contractor who is asked to price a written specification with named frequencies, test points or DBS levels gives a comparable number. One who is asked for "a clean" gives whatever number wins. The guides were published on 2 September 2026and cite the current editions: TR19 Grease and TR19 Air from BESA, the NHS National Standards of Healthcare Cleanliness 2025, Keeping Children Safe in Education, the Workplace Regulations 1992 and the Work at Height Regulations 2005.
For shorter answers, the questions page takes the fourteen questions London buyers ask most often on trade and business forums, from hourly rates and TUPE to dilapidations, and answers each in a paragraph.
