See The Difference A Professional Clean Makes
Our qualified extract engineers physically enter and reach throughout the entire duct run, plenum chambers, canopy louvres, and extract fan blades. We strip hazardous, carbonized grease back to base metal.
Cleaning requires safe access to your extraction system and relevant cooking equipment. We can discuss suitable scheduling options to help minimise disruption to your business.
How long does it take?
Most single-canopy kitchens are completed in a single overnight visit. Larger or heavily soiled systems may need additional time, which we confirm in your fixed quote before work begins.
Will insurers accept the report?
Yes. We issue a TR19 aligned certificate with before and after photographic evidence and micron readings where applicable, which is the documentation insurers and EHO officers typically ask for.
How often should it be done?
It depends on usage: heavy use kitchens every 3 months, moderate use every 6 months, and light use every 12 months. Our frequency table above is based on TR19 guidance.
Do you offer multi-site or landlord contracts?
We do. We look after pub groups, restaurant chains and managed properties across South London and Surrey on scheduled maintenance contracts. Get in touch for a tailored quote.
