Holywell questions
Do you work overnight in Holywell?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Holywell needn’t be disturbed. Just call us on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Who do I call if an extract fan fails in Holywell?
Extract fan emergencies in Holywell are covered around the clock. Use 0345 646 2711, our emergency number, at any time. Tell us where the fan is and how to reach it.
Should the fan be cleaned as well as repaired?
Often it makes sense to do both. A TR19 clean covers the canopy, plenum, ductwork and fan, with a certificate and photo report.
Is TR19 a legal requirement?
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.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Do we need to close while you work?
Normally not. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits so parts stay in use.
Will you fit a new fan if ours cannot be repaired?
Yes. A replacement is matched to the system it’s going into with a fixed price agreed before work begins.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Extract fan repair in Holywell
Think of it as a check-up for the fan: listen to it, diagnose the fault, then treat it. The aim is steady, quiet extraction and a plain account of what we found. The work covers fan housings, belts and pulleys and roof and wall fans, and the jobs we see most are a fan that won’t start at all and an old fan that needs replacing.
For a London kitchen, a failed extract fan normally means the cooking stops. In Holywell, as across London, fans often sit on a roof or deep in a plant space, so access is the first thing we ask about.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What else we do in Holywell
What we do, step by step
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 it goes on the report too. All told, the work takes part of a day for most faults, with a return visit if parts have to be ordered. Security desks and permits-to-work are routine in London, so let us know what your building in Holywell needs from us.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- Power to the fan is isolated before we open the housing.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- We explain the fault and give you a fixed price for the fix.
- The repair or replacement is carried out and the fan is run and checked.
How to prepare
- Have your last certificate or report to hand
- Allow time for equipment near the work to be turned off and cool down
- Clear the space around the work

We do not publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To start, phone us on 0345 646 2711 or use the quote form.
Advice
When something else is needed
Some problems need a different service or another trade:
- A greasy canopy and duct that a fan repair won’t touch
- Odour complaints that need filtration rather than a fan repair
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
If in doubt, phone us on 0345 646 2711 or send us an email and we’ll say what we think.
What the work covers
- Kitchen extract fans
- Fan motors
- Bearings
- Roof and wall fans
- Belts and pulleys
- Fan housings
Why it’s worth doing now in Holywell
Wherever the kitchen is, Holywell included, the fan often sits on an outside wall or roof, where a rattle or a whine can be heard beyond the kitchen. Dealing with the fault brings the noise back down before neighbours notice. 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’ll have a fixed price before work begins.

Extract fans in Holywell
Look up Holywell on the FSA’s food hygiene register and you’ll find about 141 restaurants, cafés and works canteens and about 47 takeaways in and around Holywell, up to about a mile and a half out. Those that cook under a canopy rely on a fan that runs every hour they’re open. Lifting a replacement fan onto a London roof can need a loading slot and the building’s agreement. Food hygiene inspections in Holywell are the job of Watford council’s environmental health team. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. Getting the fan running again is the priority.
Occasional-use kitchens, such as a hall kitchen near St Oswald's Parish Church or elsewhere in Holywell, are where a stiff or seized fan can turn up. For school kitchens, at schools like Westfield Academy for example, a planned fan repair in the holidays avoids losing lunches in term time.

Landmarks near Holywell
Around Holywell, our work takes us to kitchens and buildings near King George V Playing Fields, Croxley Danes School and The Red House and the streets around them. Holywell’s nearest station is Watford High Street station, roughly 1.4 miles east. Well-known places in the area include Hertfordshire Fire Brigade Museum (1.5 miles east) and Watford General Hospital (0.9 miles east). Not far away are Tumbling Bay and Chorleywood Common.
Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
What the work involves, part by part
Motors and bearings
The motor and its bearings work hardest. Hot, greasy air and long days wear them down.
Roof and wall-mounted fans
Many kitchen extract fans sit on a roof or an outside wall. Access affects how long a repair takes, so we ask about it early.
Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Save our number for the 24/7 emergency line
- Keep all filters fitted while cooking
- Make sure every filter is in place and clean
- Keep a record of any trips or stoppages
We run the fan and check it’s steady before we go. You will hear what we found and what we did along with anything else that needs watching.
A 3, 6 or 12-monthly cleaning plan brings us back at set intervals, so the fan is looked at as part of each visit and problems are spotted sooner.
