Extract fan cleaning for kitchens and businesses in Chislehurst
In Chislehurst, as everywhere we work, the fan follows a set routine: we isolate it, open the housing, scrape the impeller and degrease the lot. Your report shows the impeller as we found it and as we left it. The work covers fan housings, roof-mounted fans and centrifugal fans, and common reasons people get in touch are thick grease on the impeller and casing and burning smells from the fan area.
In London, few kitchens can spare a day to close, so work in Chislehurst is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
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, and we are fully insured.

How we price extract fan cleaning
The diagnosis comes before the price. We look at:
- One-off work versus a regular cycle
- The condition of the system
- The number of sites or systems
- How big the system is
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.
Asking for a quote
When you call or email, these details help:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Wide pictures of the system and the area around it
- The postcode and the type of business
- Any access panels or hatches you can see
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
How the job changes from site to site
Fan housings and motors
We clean around the motor without soaking its electrics, and the fan is isolated throughout. Grease around the motor can make it run hotter, so we clean what we safely can.
Roof-mounted fans
Many kitchen extracts end at a fan on the roof. They’re cleaned where safe access allows, and anything we can’t reach is recorded.
What extract fan cleaning looks like in Chislehurst
According to Food Standards Agency records, there are about 13 pubs and bars within about 1.5 miles of central Chislehurst. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected. Kitchens in Chislehurst get their food hygiene inspections from Bromley council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.
If you run catering at a healthcare site, such as a hospital like Queen Mary's Hospital about 1.6 miles east, the extract may need cleaning more often than a part-time kitchen. If you run a café or takeaway near Chislehurst station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

Common problems we fix in Chislehurst
A greasy fan in Chislehurst is fuel at the end of the duct. A fire in the duct can reach the fan and the grease around it and an overworked motor runs hotter.
The symptoms we are asked about most include:
- A fan coated in grease inside its housing
- A fan motor running hot under a coat of grease
- A fan that has never been cleaned
- Hot, greasy smells near the fan
Where a hall near Parish Church The Annunciation Of Blessed Virgin Mary, or anywhere in Chislehurst, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
What to look for in a quote

- Whether the work can be done while the site is closed
- Whether a survey comes first
- Proof of accreditation you can verify
Keeping the system healthy
After the visit, a few habits help the work last:
- Tell us if the extract feels weaker
- Keep records of every fan clean
- Notice when the fan starts to sound different
- Keep the grease filters clean and in place
Keep the report with the maintenance log and fire risk assessment. It gives a dated record of the fan’s condition, which helps if anything changes later.
Make sure the fan is reachable. A fan that can be reached safely is a fan that gets cleaned, whether it’s on a roof, in a ceiling or on a wall.
Managing agents and facilities teams in Chislehurst
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
FAQs for Chislehurst
Who inspects food businesses in Chislehurst?
In Chislehurst, it’s Bromley council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Do you do school kitchen extract cleaning in Chislehurst in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Chislehurst, the Food Standards Agency lists about 13 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you ring 0345 646 2711 or use the quote form, and we’ll fit the work in.
Do you provide a report after cleaning the fan?
A photo report, including the fan’s condition and the next clean date. Keep it with your maintenance log.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What accreditations do you have?
Duct Doctor is 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.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
Can the fan be cleaned between full cleans?
Yes, we can clean just the fan. That helps when the fan needs attention before the next full clean, but it does not replace a full TR19 clean.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
How it works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes an hour or two for most single fans. Expect the work in Chislehurst to happen after your last customer leaves, not during trading.
- We find the fan and check how it’s reached and how it’s isolated.
- The fan is isolated so it cannot start while we work.
- Grease is scraped from the impeller blades and the inside of the housing.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- We reassemble, run the fan and photograph the result.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Find the previous report, if there is one
- Arrange a key holder or contact on site

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 we can price many jobs without a visit.

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
