Extract fan cleaning for kitchens and businesses in Blendon
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. The work covers in-line fans, fan housings and roof-mounted fans, and common reasons people get in touch are a fan left out of previous cleans and thick grease on the impeller and casing.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. For a kitchen in Blendon, 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.

Your questions about extract fan cleaning in Blendon
Can you come to Blendon after we close?
Yes, nights and weekends are routine for us. It means the site in Blendon keeps running as normal. When you give us a ring on 0345 646 2711 or email us, mention when the site is quiet.
Who inspects food businesses in Blendon?
That’s Bexley council, whose environmental health officers carry out food hygiene inspections in Blendon. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
What happens if you can’t reach some of it?
Anything we cannot reach goes on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
How much does extract fan cleaning cost in Blendon?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
Do you work in Blendon?
Yes. Our technicians work in Blendon, as part of our area across London and the South East.
Grease, kitchens and Blendon
There are about 189 cafés, restaurants and staff canteens and about 85 sandwich bars and takeaways in and around Blendon, up to about a mile and a half out, according to the Food Standards Agency’s register. The fan at the end of each of those extracts collects grease that slows it and wears the motor. Fire safety in Blendon falls to London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Overnight is the normal time to clean a London kitchen extract, so trading is not affected.
If you run catering at a healthcare site, such as a hospital like Bexley Hospital about 0.8 miles north-east, the extract may need cleaning more often than a part-time kitchen. If you run a café or takeaway near Albany Park station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

What else we do in Blendon
How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, which takes an hour or two for most single fans. Expect the work in Blendon to happen after your last customer leaves, not during trading.
- Diagnosis first: we look for grease, noise and vibration.
- Once isolated, we open the fan up.
- Each blade is cleaned so the impeller runs evenly.
- Housing, outlet and the area around the motor are cleaned.
- We run the fan and note its condition in the photo report.
Before we arrive
- Mention any sign-in, permit or induction we need
- Mention any parking or loading restrictions
- Find the previous report, if there is one

Different parts, different methods
Kitchens with long cooking hours
In a busy kitchen, the fan rarely gets a rest, which means grease and wear add up quickly. Regular cleans help it keep going.
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 the surrounding area is cleaned carefully.
Common problems we fix in Blendon
How fast a fan gets greasy in Blendon depends on the cooking: daily hours and the amount of frying and grilling. BESA guidance sets minimum intervals of 3, 6 or 12 months for the whole system by daily use.
If you notice any of these, it’s worth a diagnosis:
- A heavily greased fan housing
- A fan left out of previous cleans
- A fan that no longer moves enough air
- Hot, greasy smells near the fan
Bursars and site managers at schools such as Blackfen School for Girls tend to book extract cleaning for when the kitchen is empty.
What to look for in a quote
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- How they set the interval to the next visit
- Exactly which parts of the system are covered
- How areas they can’t reach will be recorded
Why act early in Blendon
Cleaning the fan in Blendon now is a short job: the work takes an hour or two for most single fans. Waiting adds vibration, wear and a harder clean. Every month a London system goes without attention adds to what has to be done later.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Why Blendon businesses choose us
- Fixed quotes, usually within one working day
- Trading since 2009
- Every visit written up, with pictures
- We diagnose before we treat

What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
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.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Check filters are seated before cooking
- File the fan’s report with your other records
- Do not turn the fan off mid-service
- Note any drop in extraction at the canopy
Once it’s clean, the fan is closed up and run to check it’s working smoothly. Anything we notice, like noise, vibration or a worn part, goes on the report, so you can plan any repair.
Fewer grease particles reaching the fan means less build-up. Keep the grease filters clean, fitted and in place, and replace any that are damaged.
