Extract fan cleaning in Cooper's Green: the local picture
Food Standards Agency data counts about 15 cafés, restaurants and staff canteens and about 5 takeaways and sandwich shops across Cooper's Green and its immediate surroundings (about a mile and a half). The fan at the end of each of those extracts collects grease that slows it and wears the motor. Food hygiene inspections in Cooper's Green are the job of Welwyn Hatfield council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Cooper's Green 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.
Term dates shape school work: for a school like Howe Dell Primary School, an extract clean fits neatly into a half-term or summer break. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Hill End Hospital is the nearest hospital to Cooper's Green, about 2.2 miles south-west. Historic houses near Cooper's Green, such as Hatfield House about 2.7 miles east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

About our extract fan cleaning in Cooper's Green
Every TR19® Grease clean includes the extract fan, but some fans need cleaning between full cleans, for example when it’s noisy or vibrating. A fan-only clean is recorded as exactly that. If you have a fan that no longer moves enough air and a motor area thick with grease, we can help.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
FAQs for Cooper's Green
Can you come to Cooper's Green after we close?
Yes, nights and weekends are routine for us. That way a site in Cooper's Green doesn’t have to lose a day’s trading. When you give us a ring on 0345 646 2711, or send details by email, mention when the site is quiet.
Do you clean school canteen extracts around Cooper's Green out of term?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 8 schools, colleges and universities with registered kitchens within about a mile and a half of Cooper's Green. You can ring 0345 646 2711 or send us an email with the dates the site is empty.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Is TR19 a legal requirement?
No. TR19® itself isn’t law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
How often should the extract fan be cleaned?
It depends on how many hours the kitchen cooks, under BESA guidance. Heavy use means at least every 3 months, light use at least every 12, fan included.
Do we lose a day’s trading?
Typically not. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages to keep things running.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.
Different parts, different methods
Wall fans
Grease can mark the outside wall around the fan. We clean the fan and check the outlet.
Fan housings and motors
Some fans use a belt drive. We clean around them and note any wear for your records.
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Keep each photo report with the maintenance log
- Book the fan into every full TR19 clean
- Keep the fan on whenever the range is lit
- Notice when the fan starts to sound different
Once it’s clean, the fan is closed up and run to check it’s working smoothly. If anything seems wrong, from vibration to wear, we note it, so you can plan any repair.
The fan stays cleaner when less grease gets past the canopy. Keep the grease filters clean, fitted and in place, and replace any that are damaged.

- Any permits to work or inductions
What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.

What happens on the day
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes an hour or two for most single fans. We agree a date with you, plan the drive to Cooper's Green and turn up when the site is quiet.
- First we check the fan’s condition and how it sounds.
- With the fan isolated, the housing is opened.
- Each blade is cleaned so the impeller runs evenly.
- We clean the casing, the outlet and around the motor.
- The fan goes back into service with a report on its condition.
Before we arrive
- Move anything stored near the system
- Agree a time when the area can be out of use
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
