Extract fan cleaning in Cockfosters, Greater London
Extract fan cleaning for Cockfosters and the surrounding area: diagnosis first, then a fixed quote, the work and a report with photos. Ask us for a fixed quote.
- Less air being pulled from the kitchen
- Hot, greasy smells near the fan
- Thick grease on the impeller and casing
Looking after it afterwards
Results last longer with the right care. We suggest:
- Never cook with a filter missing
- Keep the fan on whenever the range is lit
- Keep access to the fan clear
- Book the fan into every full TR19 clean
Once it’s clean, the fan is closed up and run to check it’s working smoothly. Anything we notice, like noise, vibration or a worn part, goes on the report, so you can plan any repair.
Fewer grease particles reaching the fan means less build-up. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.
Extract fan cleaning for kitchens and businesses in Cockfosters
Kitchen extract fans come in different forms: roof-mounted units, inline fans within the duct, and wall fans. The way in depends on the type and the survey shows us how to reach it. If you are dealing with a noisy fan that has got louder over time and burning smells from the fan area, we can put it right, from discharge points, axial fans and in-line fans onwards.
London kitchens tend to trade late and open early, so work in Cockfosters is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

What we do, step by step
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. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes an hour or two for one fan, longer when it’s hard to reach. Getting kit into a London building takes planning, so let us know where we can load and park in Cockfosters.
- First we locate the fan and agree how it’s safely isolated.
- The fan is isolated so it cannot 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.
- It’s closed up, run and checked, and pictures go into your report.
Getting ready for the visit
- Agree a time when the area can be out of use
- Have your last certificate or report to hand
- Mention any parking or loading restrictions

Cockfosters questions
Which fire and rescue service is responsible for Cockfosters?
It’s London Fire Brigade, which covers Cockfosters. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Who inspects food businesses in Cockfosters?
That’s Enfield council, whose environmental health officers carry out food hygiene inspections in Cockfosters. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
What does extract fan cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, call 0345 646 2711 or use the quote form with the site type, opening hours and a few pictures.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
What’s the cleaning interval for an extract fan?
With the whole system, at intervals set by BESA guidance: from 3-monthly for heavy use to 12-monthly for light use. Some fans need attention sooner.
Will we have to shut during the visit?
Not typically. The area we are working in has to be out of use while we’re there, so we book a time when it would be closed anyway.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Leave it or put it right?
For a kitchen in Cockfosters, a noisy, greasy fan is often the first sign the whole system is overdue. Grease on the fan means grease in the duct before it, so it’s worth checking the whole system. It’s better booked as a planned job in Cockfosters than handled as an emergency.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before any work starts.

What affects the quote in Cockfosters
Your quote is based on your site. We take into account:
- What state the system is in
- Parking and loading at the site
- One-off work versus a regular cycle
- How big the system is
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- Any symptoms, from odd noises to smells or leaks
- The postcode and the type of business
- The roof, plant room or outside wall the system runs to
- The times we could work without disrupting the site
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Grease, kitchens and Cockfosters
The Food Standards Agency lists about 21 bars, pubs and nightclubs and about 3 hotels and guest houses as registered food businesses across Cockfosters and its immediate surroundings (about a mile and a half). Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Cockfosters sits within the area of 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. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier.
A kitchen near New Barnet station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. If you look after a school kitchen, at a school such as Trent CofE Primary School or anywhere near Cockfosters, the holidays are the usual time for a TR19® clean. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Chase Farm Hospital is the nearest hospital to Cockfosters, about 2.5 miles north-east.

What extract fan cleaning can’t fix
