How we handle extract fan cleaning in Holywell
If the ducts are the arteries, the fan is the heart. A heart under strain works harder for less. We clean it, run it and note anything that needs a closer look, before signing it off. The work covers centrifugal fans, axial fans and roof-mounted fans, and common reasons people get in touch are a heavily greased fan housing and grease escaping from the fan outlet.
In London, few kitchens can spare a day to close, so extract cleaning in Holywell is usually done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

How it works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes a few hours where there are several fans or heavy deposits. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Holywell.
- We find the fan and check how it’s reached and how it’s isolated.
- The fan is isolated so it can’t start while we work.
- Grease is scraped from the impeller blades and the inside of the housing.
- We degrease the fan and housing, taking care around the motor.
- The fan is put back into service, checked and photographed.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about permits to work or site inductions
Getting a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.

Aftercare tips
Once we’ve finished, these simple steps help:
- Watch for grease marks around the outlet
- Never cook with a filter missing
- Keep access to the fan clear
- Tell us if the extract feels weaker
The photo report shows the fan before and after cleaning. It notes what was done and anything that couldn’t be reached, along with the recommended next clean date.
Make sure the fan is reachable. Clear access means it’s never left out of a clean, whether it’s on a roof, in a ceiling or on a wall.
Multi-site and managed buildings
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, 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.
Do you need extract fan cleaning in Holywell?
By the time air reaches the fan, it has passed the canopy, filters and duct. The grease that’s left lands on the blades and the casing, and the spinning blades fling it onto the walls of the housing.
These are the problems we see most often:
- A fan that no longer moves enough air
- A fan motor running hot under a coat of grease
- Fat spreading onto the roof or wall by the fan
- A heavily greased fan housing
A hospital like Watford General Hospital, about 0.9 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

FAQs for Holywell
Who carries out food hygiene inspections in Holywell?
In Holywell, it’s Watford council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Do you work overnight in Holywell?
Yes, evening, overnight and weekend work is normal for us. That way a site in Holywell doesn’t have to lose a day’s trading. Just ring 0345 646 2711 or email us with your opening times and we’ll plan around them.
What’s the cleaning interval for an extract fan?
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.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
What about areas you cannot get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Does the law say we must follow TR19?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply call 0345 646 2711 or drop us a line.
Do you survey before quoting?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
What happens if it’s left?
A greasy fan at the discharge can spread grease onto the roof or wall around it. That stains surfaces and can add to the fire risk outside the building, which is one more reason to keep it clean. In Holywell, as across London, ductwork often passes through shared risers and other people’s space.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before we start.

Extract fan cleaning around Holywell
Food Standards Agency data counts about 141 cafés, restaurants and staff canteens and about 47 takeaways and sandwich shops across Holywell and its immediate surroundings (about a mile and a half). Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. In Holywell, food businesses are inspected by environmental health officers from Watford council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Holywell falls to London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (High Elms Manor is about 4.1 miles north), access may need planning. Volunteers running a hall kitchen near St Oswald's Parish Church, or anywhere in Holywell, may not know when the extract was last cleaned, and a grease test settles it.

Different parts, different methods
Fan housings and motors
Inside the casing, grease is thrown onto the walls. We clean it along with the blades.
Kitchens with long cooking hours
When a busy kitchen’s fan fails, cooking stops. Keeping the fan clean is part of avoiding that, and our 24/7 emergency callout is there if it happens anyway.
