About our extract fan cleaning in Barnehurst
Duct Doctor has been cleaning kitchen extract fans since 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. If you are dealing with a heavily greased fan housing and less air being pulled from the kitchen, we can help.
In a London area like Barnehurst, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What affects the cost of extract fan cleaning
Before we fix a price, we need to know a few things. We check:
- Where the site is and how we reach it
- The size of the system
- Whether several sites go on one quote
- Any permits to work or inductions
What you pay depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- Problems your staff have spotted
- The times we could work without disrupting the site
- Wide photos of the system and the area around it
- The roof, plant room or outside wall the system runs to
For extract fan cleaning in Barnehurst, give us a ring on 0345 646 2711 or drop us a line. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. A fixed quote typically follows within one working day.
How it works
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. If your building in Barnehurst has sign-in rules, permits or key holders, mention them when you book.
- 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.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Mention any locked doors, roof access or ceiling voids
- Clear the space around the work
Ask for a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.

Barnehurst kitchens: local notes
The Food Standards Agency lists about 45 bars, pubs and nightclubs and about 4 hotels and guest houses as registered food businesses within 1.5 miles or so of the middle of Barnehurst. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. London Fire Brigade covers Barnehurst. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Kitchens in Barnehurst get their food hygiene inspections from Bexley council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Erith and District Hospital is the nearest hospital to Barnehurst, about 1.1 miles north. A kitchen near Barnehurst station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. School kitchens, at schools like Mayplace Primary School for example, are normally cleaned in the holidays so no lunches are lost.
Barnehurst is about 3 miles east of Welling, in Greater London. We carry out extract fan cleaning for businesses, landlords and public buildings in Barnehurst and the rest of Greater London. We cover 764 places across Greater London, large and small. London is in our area too, around 12 miles away.
Our technicians cover all of DA7, DA1 and DA8 for extract fan cleaning and the roads nearby. Whether your site is on Old Road, Grove Road and Manor Road or a nearby road, we can help. Barnehurst is on the A2000, so it’s easy for us to get to for out-of-hours visits. If your site is just outside Barnehurst, we cover Bexley Riverside (1 mile north), Northumberland Heath (1 mile north), Crayford (1 mile south-east), North End (1 mile east) and Barnes Cray (1 mile east). Within a short drive, we also cover London (12 miles west), City of Westminster (14 miles west), Marylebone (14 miles west), St Pancras (13 miles west), Shoreditch (12 miles north-west) and Walthamstow (12 miles north-west).
Around Barnehurst
Around Barnehurst, our work takes us to kitchens and buildings near St Catherine's Catholic School, St Catherine's Catholic School and Braeburn Park. Barnehurst’s nearest station is Barnehurst station, about 0.5 miles north-west of the centre. Other landmarks nearby include Stone Castle (4.8 miles east) and Bexley Museum (1 mile south). Green spaces nearby include Wansunt Pit.
Staff cleaning versus specialist work
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Barnehurst questions
Can school kitchens in Barnehurst be cleaned in the holidays?
Yes, holiday work suits schools best. There are about 28 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Barnehurst. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Who is the fire and rescue service for Barnehurst?
Barnehurst is in the area of London Fire Brigade. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
What paperwork do I get after a fan clean?
Every clean has a photo report, along with notes on the fan’s condition. A full clean adds a TR19 certificate from the BESCA Vent Hygiene Elite portal.
Do you need to turn the fan off to clean it?
With the fan isolated, the extract isn’t running. That’s why fan cleans are done out of hours, and the kitchen is ready when we leave.
Is TR19 cleaning required by law?
No. TR19® itself is not law; it’s a BESA specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Do you work in Barnehurst?
Yes. Barnehurst is part of the area we cover, as part of our area across London and the South East.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
When something else is needed
A few issues sit outside what this work can do:
- A fan that will not start
- A fan that was never right for the kitchen
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
If in doubt, ring 0345 646 2711, or send details by email and we will say what we think.
Parts of the system we cover
- Discharge points
- Centrifugal fans
- Roof-mounted fans
- In-line fans
- Fan housings
- Axial fans
How the job changes from site to site
Fan housings and motors
The housing around the impeller catches grease flung off the blades. We clean it along with the blades.
Inline duct fans
Hidden in a ceiling void, an inline fan is easily missed. The survey makes sure it’s part of the clean.
Multi-site and managed buildings
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Why deal with it now?
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. A busy site in Barnehurst builds up dirt and wear quickly, so putting it off makes the eventual job larger.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.
