Hertfordshire · Extract fan cleaning
Fields End extract fan cleaning
For cleaning of kitchen extract fans, impellers, fan housings and discharge points in Fields End, one call is all it takes: survey, fixed quote, work and sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- Grease stains around the discharge
- Hot, greasy smells near the fan
- A fan that no longer moves enough air
Keeping the system healthy
A little care between visits keeps the system in better shape. Our advice:
- Watch for grease marks around the outlet
- Never cook with a filter missing
- Make sure the fan is included each time
- Keep access to the fan clear
The area around the fan is left clean, with waste grease removed. On a roof or outside wall, we leave the surrounding area tidy.
Stick to the interval for the full extract. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
How we handle extract fan cleaning in Fields End
Duct Doctor has been cleaning kitchen extract fans since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we’re fully insured, with CHAS, SafeContractor and ISO 9001. We are often asked to deal with hot, greasy smells near the fan and a fan that no longer moves enough air, across centrifugal fans, roof-mounted fans and fan housings.
Somewhere as small as Fields End, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Signs you need extract fan cleaning in Fields End
The fan sits at the end of the grease’s journey. Whatever grease is still in it settles on the impeller and inside the housing where the spinning blades spread it around.
It’s time to book a visit if you see:
- Hot, greasy smells near the fan
- A motor area thick with grease
- A fan left out of previous cleans
- Grease stains around the discharge
Term dates shape school work: for a school like John F Kennedy Catholic School, an extract clean fits neatly into a half-term or summer break.

What extract fan cleaning looks like in Fields End
There are about 20 restaurants, cafés and canteens and about 14 takeaways within about 1.5 miles of central Fields End, according to the Food Standards Agency’s register. Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. Food hygiene inspections in Fields End are the job of Dacorum council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked. Fields End is covered by Hertfordshire 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.
Healthcare kitchens, like those at hospitals such as Hemel Hempstead Hospital (about 1.9 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands. Where a hall near St Alban's Church, or anywhere in Fields End, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Fields End is about 2 miles west of Hemel Hempstead, in Hertfordshire. Every kind of commercial site in Fields End, extract fan cleaning is something we can help with.

Questions from Fields End
Do you do school kitchen extract cleaning in Fields End in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 12 schools and colleges with food registrations within roughly a mile and a half of Fields End. Send us your term dates when you call 0345 646 2711, or send details by email, and we will fit the work in.
Is Fields End within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Fields End included. A survey first, from photos or a visit, means we arrive with the right kit.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
How much notice should we give?
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.
Will we have to shut during the visit?
Not normally. The area we are working in has to be out of use while we’re there, so the visit goes in a quiet slot.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
How often does the fan need cleaning?
Daily cooking hours set the minimum in BESA guidance. Heavy use means at least every 3 months, light use at least every 12, fan included.
Does a TR19 kitchen extract clean cover the fan?
Yes. The whole system is cleaned, from the canopy to the discharge, and the fan sits right in that path, so it’s cleaned too.
What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what extract fan cleaning will not do:
- Grease in the canopy and ductwork
- A motor that has burnt out
- Electrical faults in the fan’s supply or controls (an electrician’s job)
Not sure which it is? You can give us a ring on 0345 646 2711 or send us an email and we’ll tell you honestly before booking.

What your team can do, and what needs us
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
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
When a busy kitchen’s fan fails, cooking stops. A clean fan is less likely to strain, and our 24/7 emergency callout is there if it happens anyway.
Impellers and blades
The blades of the impeller do the work, and it collects grease unevenly. An uneven coating throws it off balance, so it’s cleaned carefully blade by blade.

What else we do in Fields End
What affects the cost of extract fan cleaning
A fixed price needs a few facts first. We check:
- The condition of the system
- Any permits to work or inductions
- How many systems or sites are involved
- One-off work versus a regular cycle
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before any work starts.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Your opening hours and when the area is out of use
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
- Close-ups of filters, grilles, hatches or access panels
To get a fixed quote, call 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We normally come back within one working day.
What happens on the day
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a couple of hours per fan, depending on its size and the build-up. Somewhere like Fields End, lanes, gates and parking are worth mentioning in advance.
- We locate the fan and plan how to reach and isolate it.
- It’s isolated so it cannot run while we work.
- We scrape the heavy grease from the blades and housing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
Before we arrive
- Let us know when the site is closed or quiet
- Mention any parking or loading restrictions
- Clear loose items from the work area
Get a fixed quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
