How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes an hour or two for most single fans. Pictures of the system and its access let us plan the work in Monkswood before we set off.
- We locate the fan and plan how to reach and isolate it.
- It’s isolated so it can’t run while we work.
- Grease is scraped off the impeller blades and casing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
How to prepare
- Clear loose items from the work area
- Tell us where we can park and unload
- Mention any locked doors, roof access or ceiling voids

What extract fan cleaning looks like in Monkswood
Food Standards Agency records include about 15 pubs, bars and clubs within about 1.5 miles of central Monkswood. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. It’s Welwyn Hatfield council that sends environmental health officers to food businesses in Monkswood. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Monkswood falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you run a church or community hall kitchen, near The Parish Church of St John or elsewhere in Monkswood, its extract still collects grease from every lunch and event. Commuter trade near Welwyn North station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Term dates shape school work: for a school like Homerswood Primary and Nursery School, an extract clean fits neatly into a half-term or summer break.

Why act early in Monkswood
A greasy fan has to work harder to move the same air. Less air is pulled from the kitchen, so heat and smoke linger, while the motor runs under more strain. A fault that closes a site in a village like Monkswood affects everyone who depends on it.

What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Part by part
Kitchens with long cooking hours
A long-hours kitchen cannot afford a fan failure. Keeping the fan clean is part of avoiding that, and our 24/7 emergency callout is there if it happens anyway.
Inline duct fans
Inline fans can be in tight spaces, so we plan how to reach and clean them. Anything out of reach is recorded.
Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Look for grease stains near the discharge
- Check the report shows the fan was cleaned
- Do not store items in front of the fan’s access point
- Flag smoke lingering at the canopy
When the fan is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.
Keep the whole system on its cleaning cycle. Regular full cleans keep the fan from building up heavy deposits, in line with BESA guidance.
