Petersham extract fan cleaning
Our technicians work in Petersham on cleaning of kitchen extract fans, impellers, fan housings and discharge points. Out-of-hours visits, a fixed quote and a written report with pictures on every job.
- Vibration from an unbalanced impeller
- Thick grease on the impeller and casing
- A smell of hot grease from the extract
What a clean will not put right
Before you book, it helps to know what’s not included:
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
- A motor that has burnt out
- A fan that was never right for the kitchen
If you are not sure, just ring 0345 646 2711 or drop us a line and we will give you a straight answer before you book.

Extract fan cleaning in Petersham
Grease on a fan is not spread evenly. Heavier deposits on some blades throw the impeller off balance, leading to vibration, noise and strain on the motor and bearings. A thorough clean removes the cause. If you’re dealing with less air being pulled from the kitchen and a heavily greased fan housing, we can help, from axial fans, in-line fans and fan housings onwards.
Kitchens in Petersham, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
Duct Doctor has been trading since 2009, as 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.

Managing agents and facilities teams in Petersham
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
Petersham: your questions answered
Who would carry out a food hygiene inspection at a kitchen in Petersham?
The local authority for Petersham is Richmond-Upon-Thames council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Who enforces fire safety at workplaces in Petersham?
Fire safety enforcement in Petersham is handled by London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
What do you do with what you remove?
We take it away at the end of the visit. During the work, it’s contained so the area stays clean.
Will I get pictures of the cleaned fan?
A photo report, including the fan’s condition and the next clean date. File it with your other extract records.
How much notice should we give?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
What should I send you?
A short description and a few photos, with the address and opening hours. We’ll ask for anything else we need.
Should the extract fan be cleaned as part of TR19?
Yes, a full TR19 clean includes the fan. Anything that cannot be reached is recorded, so you always know what was cleaned.
What accreditations do you have?
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.

What else we do in Petersham
Between visits
After the visit, a few habits help the work last:
- Listen for new noises or vibration from the fan
- Don’t store items in front of the fan’s access point
- Keep the fan on whenever the range is lit
- Flag smoke lingering at the canopy
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.
Fewer grease particles reaching the fan means less build-up. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.
Kitchen extracts in Petersham
Look up Petersham on the FSA’s food hygiene register and you will find about 224 restaurants, cafés and canteens and about 21 takeaways and sandwich shops within roughly a mile and a half of the centre of Petersham. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. Environmental health officers from Richmond-Upon-Thames council inspect food businesses in Petersham. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand. Petersham is covered by London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
For kitchens close to St Margarets (London) station, where the day often starts early and ends late, the extract can be cleaned overnight. Volunteers running a hall kitchen near St Peter's Church, or anywhere in Petersham, may not know when the extract was last cleaned, and a grease test settles it. Term dates shape school work: for a school like The Russell Primary School, an extract clean fits neatly into a half-term or summer break.

How we price extract fan cleaning
The diagnosis comes before the price. We look at:
- A single visit or a regular plan
- The size of the system
- Access, including roofs, risers and ceiling voids
- Site requirements such as sign-in and permits
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.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
- The site address and the type of premises
To help us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Once you have those, call 0345 646 2711 or use the quote form.
The process
Each visit runs to the same pattern: protect the area, make the system safe, carry out the extract fan cleaning, clear away and leave you the report. On site, the work takes an hour or two for most single fans. In Petersham, as across London, we normally work overnight or at weekends and hand the site back ready to open.
- 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
- Move anything stored near the system
- Name a contact who can let us in at the agreed time
- Tell us about site rules, permits or sign-in
Getting a quote
The quickest way to a quote is to send pictures: 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.
Advice
What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Why act early in Petersham
Grease on the fan is grease in the system. A TR19 clean that left out the fan wouldn’t cover the whole system, and insurers asking for TR19 cleaning expect the full system. Planning ahead in Petersham lets you pick a quiet night rather than lose a busy one.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.
