What extract fan cleaning looks like in Hayes
The FSA’s data shows about 19 pubs, bars and clubs registered within about 1.5 miles of central Hayes. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Fire safety in Hayes falls to London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Hayes, food businesses are inspected by environmental health officers from Bromley council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
School kitchens, at schools like Hawes Down Primary School for example, are normally cleaned in the holidays so no lunches are lost. A hospital like National Psychosis Unit, about 1.6 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Extract fan cleaning in Hayes, done properly
A clean fan isn’t a repaired fan. Anything that looks worn or damaged goes on the report and fan repair or replacement is something we also do. You get an honest view of the fan’s condition. Typical jobs include an extract fan with no cleaning record and rough running from the extract fan, on in-line fans, roof-mounted fans and fan housings.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Hayes, that normally means a longer system to clean and more access panels to plan around.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What the work involves, part by part
Roof-mounted fans
Roof fans also discharge grease onto the roof around them and we check the area around the outlet. We note any grease around the fan.
Impellers and blades
Grease on the leading edges of the blades cuts the fan’s efficiency. Scraping and degreasing them restores their shape, so the fan can run as intended.
When to call us in Hayes
Grease builds up unevenly on the blades. The difference throws the impeller off balance and puts strain on the bearings. Left too long, grease turns into wear.
If you notice any of these, it’s worth a diagnosis:
- Less air being pulled from the kitchen
- A fan shaking on its mounts
- A fan left out of previous cleans
- Thick grease on the impeller and casing
If you cook for passing trade around Hayes (Kent) station, the extract can be cleaned between your last and first customer.

How the visit works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes an hour or two for most single fans. Before any visit in Hayes, we agree where the van can stop and how equipment reaches the system.
- We locate the fan and plan how to reach and isolate it.
- We isolate the power before opening the housing.
- Grease is scraped off the impeller blades and casing.
- The fan is degreased, taking care around the motor.
- We reassemble, run and photograph the fan.

- Tell us about site rules, permits or sign-in
- Find the previous report, if there is one
How to get a quote
Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
What happens if it’s left?
Grease on a roof fan can also escape outside. That stains surfaces and can add to the fire risk outside the building, which is one more reason to keep it clean. Leaving it on a busy London site only adds to the work.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

Common questions in Hayes
Can the work in Hayes be done at night or at weekends?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Just call us on 0345 646 2711, or send details by email with your opening times and we will plan around them.
Is parking a problem for work in Hayes?
Tell us where a van can stop near your site in Hayes, and about any building rules on loading. If the building has a loading slot system, we will book into it.
Will we have to shut during the visit?
Not normally. We need the work area to ourselves while we are on site, so we book a time when it would be closed anyway.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Can you fix a fan that is worn out?
Anything beyond cleaning is flagged, with what we found. We can repair or replace it, and if it fails outright, our 24/7 emergency line is there.
What makes a kitchen extract fan vibrate?
An unbalanced impeller, normally from uneven grease, is a common cause. After cleaning, we will tell you if wear or damage is also involved.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Keeping the system healthy
After the visit, a few habits help the work last:
- Look for grease stains near the discharge
- Keep the grease filters clean and in place
- Notice when the fan starts to sound different
- Leave a clear route to the fan
Once it’s clean, the fan is closed up and run to check it’s working smoothly. If anything seems wrong, from vibration to wear, we note it, so you can plan any repair.
The fan stays cleaner when less grease gets past the canopy. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.
When something else is needed
Before booking, it helps to know what’s not included:
- A cracked or broken impeller (it needs replacing)
- A motor that has burnt out
- A dirty duct upstream of the fan
If you’re not sure, just phone us on 0345 646 2711 or use the quote form and we will give you a straight answer before booking.
