Extract fan cleaning around St Margarets
The Food Standards Agency lists about 4 bars, pubs and nightclubs as registered food businesses within 1.5 miles or so of the middle of St Margarets. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kitchens in St Margarets get their food hygiene inspections from Sevenoaks council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. St Margarets sits within the area of Kent Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
If you run a church or community hall kitchen, near Church of St Margaret of Antioch or elsewhere in St Margarets, its extract still collects grease from every lunch and event. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Lullingstone Castle is about 4.5 miles south-west), access may need planning.

How we handle extract fan cleaning in St Margarets
Every TR19® Grease clean includes the extract fan, but some fans need cleaning between full cleans, for example when it’s noisy or vibrating. Where only the fan is cleaned, the report says so. Common call-outs are for fat spreading onto the roof or wall by the fan and a fan motor running hot under a coat of grease, across fan housings, roof-mounted fans and axial fans.
For a kitchen in or near St Margarets, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

How it works
There are three stages on the day: 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 one fan, longer when it’s hard to reach. If the van will struggle with a lane or gateway near St Margarets, let us know and we will plan around it.
- Diagnosis first: we look for grease, noise and vibration.
- 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.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Tell us the best time to work, such as after service or at a weekend
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
Quotes are quick. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Advice
Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Tell us if the extract feels weaker
- Notice when the fan starts to sound different
- Do not turn the fan off mid-service
- Check filters are seated before cooking
Keep the report with the maintenance log and fire risk assessment. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
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.

What else we do in St Margarets
Part by part
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.
Roof-mounted fans
Roof fans also discharge grease onto the roof around them and we check the area around the outlet. Heavy staining is noted on the report.
Why it’s worth doing now in St Margarets
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. Out of sight is the usual reason a rural system goes too long without attention.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.

Signs you need extract fan cleaning in St Margarets
How fast a fan gets greasy in St Margarets 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.
Common reasons sites call us include:
- Rough running from the extract fan
- Grease escaping from the fan outlet
- Thick grease on the impeller and casing
- A smell of hot grease from the extract

Questions from St Margarets
Is St Margarets within the area you cover?

A single accessible fan does not take long, while fans on high roofs or in tight voids take longer. We plan it out of hours.

Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What’s the cleaning interval for an extract fan?
The fan follows the full system’s interval at BESA’s minimum intervals for your cooking hours. Readings may show it needs cleaning more often.
What extract fan cleaning cannot fix
Some problems need a different service or another trade:
- A fan that is too small for the system (a design question)
- An impeller that’s bent or split
- A failed motor or worn bearings (that needs a fan repair or replacement)

Managing agents and facilities teams in St Margarets
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
