Who We Are.
Specialists, Not General Cleaners.
Extract Compliance Ltd was built by engineers who have spent more than 15 years inside commercial kitchen canopies, ductwork runs, laundry extracts and air handling units — for restaurants, pubs, hotels, schools, care homes, NHS premises, local authorities and national chains.
Ventilation hygiene is all we do. Our engineers work to written risk assessments and method statements and are used to operating discreetly around live sites — early mornings, evenings, weekends and overnight, so your kitchen never has to close for us.
We would rather tell you the truth about your system than sell you a clean you do not need. If a duct run is inaccessible, an access panel is missing, or a filter is beyond cleaning, it goes in the report with a clear recommendation and a price — no surprises.

Our Standards & Reporting.
Compliance You Can Rely On.
A clean system is only half the job. What protects your business in an insurance claim, a fire risk assessment or an Environmental Health visit is the documentation that proves the work was done properly.
How We Work On Site
- ✓Pre-clean survey and grease/dust deposit thickness measurements taken at set test points.
- ✓Access panels inspected and, where required, new BESA-compliant panels fitted to reach every duct run.
- ✓Mechanical rotary brushing, hand scraping and specialist degreasing back to bare metal — not just the visible areas.
- ✓Negative pressure vacuum units and containment used to keep dust out of your kitchen or occupied space.
- ✓Post-clean verification measurements to confirm the system meets the required standard.
- ✓Out-of-hours, overnight and weekend working so your business keeps trading.
