FAQs for Chobham
Do you work overnight in Chobham?

Which fire authority looks after Chobham?
Fire safety enforcement in Chobham is handled by Surrey Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Which accreditations do you hold?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
How often does the fan need cleaning?
At least as often as the rest of the extract, which BESA guidance sets by daily cooking hours: from 3-monthly for heavy use to 12-monthly for light use. A noisy or heavily coated fan may need it sooner.
Should the extract fan be cleaned as part of TR19?
Yes, the fan is cleaned as part of TR19. Anything that can’t be reached is recorded, so the record is accurate.
How we handle extract fan cleaning in Chobham
Duct Doctor has been cleaning kitchen extract fans since 2009. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. We are often asked to deal with a fan left out of previous cleans and grease around the motor and its mounts, across centrifugal fans, axial fans and discharge points.
For a smaller kitchen near Chobham, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Leave it or put it right?
Without a working extract fan, a kitchen can’t cook safely. Many fan problems start with grease, so cleaning the fan helps keep it working. If it does fail, our 24/7 emergency line is there. Booking ahead lets us plan the trip to Chobham at a time that suits you.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before work begins.

Extract fan cleaning around Chobham
There are about 12 restaurants, cafés and canteens across Chobham and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Any of those kitchens with a canopy relies on a fan that gathers grease as it runs. Food hygiene inspections in Chobham are the job of Surrey Heath council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. Surrey Fire and Rescue Service covers Chobham. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Brookwood Hospital is the nearest hospital to Chobham, about 2.7 miles south. Bursars and site managers at schools such as St Lawrence CofE (Aided) Primary School tend to book extract cleaning for when the kitchen is empty.

What we do, step by step
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes a couple of hours per fan, depending on its size and the build-up. We plan the journey to Chobham and bring what the job is likely to need.
- First we check the fan’s condition and how it sounds.
- With the fan isolated, the housing is opened.
- The impeller is cleaned blade by blade so it runs balanced.
- We clean the casing, the outlet and around the motor.
- We run the fan and note its condition in the photo report.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Let us know about permits to work or site inductions
- Clear loose items from the work area

Advice
Do you need extract fan cleaning in Chobham?
How fast a fan gets greasy in Chobham depends on the cooking: how many hours a day the kitchen runs and what it cooks. Under BESA guidance, the whole system, fan included, needs cleaning at least every 3, 6 or 12 months depending on daily hours.
Keep an eye out for these warning signs:
- Burning smells from the fan area
- A fan motor running hot under a coat of grease
- A fan that hums, whines or rumbles
- A fan coated in grease inside its housing
Historic houses near Chobham, such as Botleys Mansion about 3.2 miles north-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
What to look for in a quote
- Whether they’re fully insured
- Exactly which parts of the system are covered
- Whether they recommend a next date
- How VAT is shown on the quote
Between visits
Aftercare is simple, and it helps at the next visit:
- Run the extract throughout cooking
- Never cook with a filter missing
- Tell us if the extract feels weaker
- Look for grease stains near the discharge
If the fan needs more than a clean, we’ll say so plainly. Fan repair and replacement are services we offer too, so you have one point of contact.
Keep the whole system on its cleaning cycle. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
Part by part
Fan housings and motors
We clean around the motor without soaking its electrics, and the fan is isolated throughout. Grease on and around the motor can trap heat, so we clean what we safely can.
Impellers and blades
Coated blades move less air. We clean each blade back to its surface, so the fan can run as intended.
When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what extract fan cleaning won’t do:
- A fan that was never right for the kitchen
- A fan that won’t start
- A dirty duct upstream of the fan
If you’re not sure, just call 0345 646 2711 or email us and we will give you a straight answer before booking.
