Landlords, agents and facilities managers
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
Ductwork cleaning for kitchens and businesses in Crabtree
We’ve been trading since 2009, working across London and the South East. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with each certificate issued through the BESCA portal. The work covers horizontal duct runs, bends and junctions and access panels, and the jobs we see most are grease seeping out of the duct seams and years of grease along the duct floor.
In a village or hamlet like Crabtree, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

How the visit works
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the ductwork cleaning, tidy up and hand over the paperwork. The visit itself takes anything from a few hours to several visits, depending on the length of duct. Rural roads and tight entrances are worth telling us about before a visit to Crabtree.
- The duct route is surveyed and every access point found.
- We take grease readings along the route.
- Out of hours, the area is protected and the access panels opened.
- Heavy deposits come out by hand, then each section is degreased.
- We close up, re-test, photograph and record anything out of reach.
Before we arrive
- Tell us about site rules, permits or sign-in
- Dig out any earlier paperwork for the system
- Let us know how we reach the system, including roofs, risers and plant rooms

Related advice
Crabtree: your questions answered
Do you work in villages like Crabtree?
Yes, Crabtree is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Which fire authority looks after Crabtree?
Crabtree is in the area of West Sussex Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
What’s involved in cleaning extract ducts?
We get into the duct through its access panels. Thick deposits are removed by hand before degreasing, such as degreasers, hot water or steam.
Will the duct clean disrupt the kitchen?
We plan the clean when you are not cooking. Overnight and weekend work is common, so no service is lost.
How can I tell if my extract ducts are dirty?
The date on the last certificate is the first thing to check. No record, or a passed date, means it’s due, and grease readings will confirm how urgent it is.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.
Do you have insurance?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Part by part
Bends and transitions
Transitions from the canopy spigot into the duct catch a lot of grease. We clean it from the canopy side or through a nearby panel.
Attenuators and discharge
Attenuators, where fitted, quieten the extract, but they can hold grease in their linings. We clean what can be reached and note anything that can’t.

What we are called out for in Crabtree
Grease filters that do not seal let fat straight through. The duct then takes grease that the filters should have stopped and it fills faster.
Most sites get in touch after spotting something like this:
- Grease pooling at the foot of the riser
- Readings above 200 microns from a grease thickness test
- A duct clean needed for an insurer
- Ductwork that has never been cleaned
Term dates shape school work: for a school like Newells Preparatory School, an extract clean fits neatly into a half-term or summer break.

Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Crabtree kitchens: local notes
In Crabtree, food businesses are inspected by environmental health officers from Horsham council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in Crabtree falls to West Sussex Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Volunteers running a hall kitchen near Old Church House the Glebe, or anywhere in Crabtree, may not know when the extract was last cleaned, and a grease test settles it. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Horsham Hospital is the nearest hospital to Crabtree, about 4.9 miles north-west.

Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Leave a way through to the access panels
- Get panels fitted where the duct couldn’t be cleaned
- Check readings when the menu changes
- Keep your cleaning records together
You will have a recommended date for the next clean, based on the readings and your daily cooking hours, in line with BESA guidance.
Grease that never reaches the duct never needs cleaning out of it. Keep the filters clean, well fitted and in place whenever you cook.
