About our extract fan cleaning in Ham
Every TR19® Grease clean includes the extract fan, but some fans need cleaning between full cleans, for example when it’s noisy or vibrating. A fan-only clean is recorded as exactly that. If you’re dealing with grease around the motor and its mounts and a fan that no longer moves enough air, we can help, from in-line fans, fan housings and axial fans onwards.
In a London area like Ham, 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, so a regular TR19® clean protects everyone in it.
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’re fully insured.

Questions from Ham
Is parking a problem for work in Ham?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Can school kitchens in Ham be cleaned in the holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 21 schools, colleges and universities with registered kitchens within about a mile and a half of Ham. Tell us your holiday dates and we’ll book the visit for when the site is empty.
What’s the cleaning interval for an extract fan?
Daily cooking hours set the minimum in BESA guidance. At the extremes, that’s 3-monthly for heavy use and 12-monthly for light use, fan included.
What makes a kitchen extract fan vibrate?
Uneven grease on the impeller often causes it. We clean the fan and tell you if anything else, like worn bearings, is to blame.
Are you insured?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Do you provide a report after cleaning the fan?
Photos, notes on condition and a recommended next date. Keep it with your maintenance log.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Will we have to shut during the visit?
Not usually. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits so parts stay in use.

What else we do in Ham
Different parts, different methods
Wall fans
Grease can mark the outside wall around the fan. We clean the fan and check the outlet.
Roof-mounted fans
Roof fans sit at the top of the riser. We clean them where they can be safely reached, with any limits noted.
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Listen for new noises or vibration from the fan
- Leave a clear route to the fan
- Tell us if the extract feels weaker
- Watch for grease marks around the outlet
When the fan is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.
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.
Signs you need extract fan cleaning in Ham
Fans that are hard to reach are often the ones that get missed. If it wasn’t included in past cleans, it may hold years of grease, and the report will show it.
Most sites get in touch when they notice one of these:
- Hot, greasy smells near the fan
- Grease stains around the discharge
- Vibration from an unbalanced impeller
- Rough running from the extract fan
Volunteers running a hall kitchen near Ham Christian Centre, or anywhere in Ham, may not know when the extract was last cleaned, and a grease test settles it.
Questions to ask before you book
- Whether a written report and photos are included
- Whether the quote shows VAT
- Whether the price is fixed
- Whether inaccessible sections are listed on the report
What happens on the day
Every visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, tidy up and hand over the paperwork. The visit itself takes an hour or two for one fan, longer when it’s hard to reach. For a job in Ham, tell us about loading bays, permits, lifts and roof access when you book.
- The fan is found and its type, access and isolation checked.
- It’s isolated so it cannot run while we work.
- We scrape the heavy grease from the blades and housing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
Getting ready for the visit
- Tell us where we can park and unload
- Make sure someone can let us in and lock up afterwards
- Move anything stored near the system

Advice
When it’s something else
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- A fan that was never right for the kitchen
- Wiring faults to the fan
- An impeller that is bent or split
Not sure which it is? You can call 0345 646 2711 or email us and we’ll tell you honestly.

Ham kitchens: local notes
According to Food Standards Agency records, there are about 38 pubs, bars and clubs within about 1.5 miles of central Ham. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Night work suits London kitchens, and roads and loading bays tend to be quieter too. London Fire Brigade covers Ham. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Healthcare kitchens, like those at hospitals such as Teddington Memorial Hospital (about 1.5 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Ham House is about 0.6 miles north), access may need planning.
Ham is about 1 mile south-east of Twickenham, in Greater London. Every kind of commercial site in Ham, we can take on extract fan cleaning. We can work out of hours so trading isn’t interrupted. Ham is one of 764 places in Greater London where we work for commercial clients. Our London page covers sites nearby (10 miles or so).
Our technicians cover all of TW10, KT2 and TW11 for extract fan cleaning and the streets around it. Whether your site is on New Road, Lock Road and Cave Road or a nearby road, our technicians can take on the work. Main roads around Ham include the A307, so getting to you is simple for evening and night visits. Nearby, we also carry out extract fan cleaning in Petersham (1 mile north), Eel Pie Island (1 mile north-west), Strawberry Hill (1 mile west), Teddington (1 mile south-west) and Richmond (1 mile north). Within a short drive, we also cover London (10 miles north-east), City of Westminster (9 miles north-east), Marylebone (9 miles north-east), Kensington (6 miles north-east), St Pancras (10 miles north-east) and Shoreditch (12 miles north-east).
Around Ham
We work in commercial kitchens and buildings around Grey Court School, The New Inn Public House and Sudbrook Park. Ham’s nearest station is Teddington station, roughly 1.2 miles south-west. A little further out are Eel Pie Island Museum (1.1 miles north-west) and Bentall Centre (1.6 miles south). Open spaces near Ham include Kew Gardens Lake and Richmond Hill.
How we price extract fan cleaning
We don’t publish a price list, because no two systems are the same. The quote depends on:
- The scale of the work
- Where the site is and how we reach it
- Whether we need access equipment or extra panels
- The condition of the system
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.
Asking for a quote
To speed up the quote, please include:
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Why act early in Ham
A fan that sounds rough in Ham is often telling you the extract needs a clean. If the fan is coated, the duct before it typically is too so a full TR19 clean may be due. A booked night’s work in Ham costs you no trading time; an unplanned closure does.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
