How we handle extract fan cleaning in Watford
If the ducts are the arteries, the fan is the heart. A greasy fan works harder and moves less air. We clean it, run it and note anything that needs a closer look so you get a clean bill of health. Common call-outs are for hot, greasy smells near the fan and a fan that hums, whines or rumbles, on in-line fans, centrifugal fans and axial fans.
Town-centre kitchens in a place like Watford often sit below flats or offices, with risers that run up the back of the building to roof level. Vertical risers like that need access panels in the right places, and any section we can’t reach is recorded on the report.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Watford questions
Do you do school kitchen extract cleaning in Watford in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 40 schools and colleges with food registrations within roughly a mile and a half of Watford. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can the work in Watford be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The work in Watford can fit around your hours. Just call 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
How do you keep the site clean during the work?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
What does extract fan cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll usually reply within one working day.
What happens if you cannot reach some of it?
Anything we can’t reach goes on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
What do you need from me for a quote?
A short description and a few pictures, with the address and opening hours. If we need more, we’ll ask.
What affects the quote in Watford
The diagnosis comes before the price. The main factors are:
- The number of sites or systems
- The size of the system
- Parking and loading at the site
- What state the system is in
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- The postcode and the type of business
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
- How we’d reach plant on a roof or in a plant room

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
The housing around the impeller catches grease flung off the blades. We clean it along with the blades.

Honest limits
It’s worth knowing the limits before booking:
- A cracked or broken impeller (it needs replacing)
- A fan that’s too small for the system (a design question)
- 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 use the quote form and we’ll tell you honestly before booking.

What happens on the day
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes an hour or two for one fan, longer when it’s hard to reach, and the area is cleaned down before we leave. We’ll ask where we can park in Watford and how to get equipment to the system, as those shape the visit.
- First we locate the fan and agree how it’s safely isolated.
- Power to the fan is isolated before anyone touches it.
- The impeller and the housing around it are scraped clean.
- Blades, housing and the area around the motor are degreased with care.
- The fan is put back into service, checked and photographed.
Getting ready for the visit
- Have your last certificate or report to hand
- Clear the space around the work
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
What your team can do, and what needs us
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Extract fan cleaning around Watford
Look up Watford on the FSA’s food hygiene register and you’ll find about 218 restaurants, cafés and canteens and about 68 takeaways and sandwich shops within about 1.5 miles of central Watford. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. Environmental health officers from Watford council inspect food businesses in Watford. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Watford falls to Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
If you run catering at a healthcare site, such as a hospital like Watford General Hospital about 1.1 miles south, the extract may need cleaning more often than a part-time kitchen. For schools such as Watford St John's Church of England Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed. A hall kitchen that only cooks for events, whether near Church of St Andrew or elsewhere in Watford, still needs its extract cleaned, just less often.

Why act early in Watford
Vibration from an unbalanced impeller does not stay small. It wears bearings and mounts and can lead to a breakdown, which may leave the kitchen without extraction. Cleaning it early is far less disruptive. A regular plan for a site in Watford spreads the work out and keeps every system on track.

Between visits
Think of this as the after-treatment advice, short and simple:
- Don’t turn the fan off mid-service
- Keep each photo report with the maintenance log
- Do not store items in front of the fan’s access point
- Watch for grease marks around the outlet
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. If only the fan is cleaned, the photo report says so.
Keep the whole system on its cleaning cycle. Regular full cleans keep the fan from building up heavy deposits, in line with BESA guidance.
