Extract fan cleaning for kitchens and businesses in Thamesmead
A fan never collects grease in a neat, even layer. Uneven build-up unbalances the impeller, leading to vibration, noise and strain on the motor and bearings. A thorough clean removes the cause. Typical jobs include rough running from the extract fan and fat spreading onto the roof or wall by the fan, across in-line fans, fan housings and discharge points.
In London, few kitchens can spare a day to close, so extract cleaning in Thamesmead is typically done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What affects the cost of extract fan cleaning
The survey tells us what the work involves. The main factors are:
- The condition we find in the survey
- How big the system is
- Site rules, permits and inductions
- The times the site is available
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.
What we need to know
To help us quote quickly, send us:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Photos showing the whole system and its surroundings
- The postcode and the type of business
- Your opening hours and when the area is out of use
If you need extract fan cleaning in Thamesmead, ring 0345 646 2711, or send details by email. Tell us what kind of premises it is and when it’s open, plus pictures or the previous report if they’re to hand. A fixed quote normally follows within one working day.
Leave it or put it right?
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. Leaving it on a busy London site only adds to the work.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.

Questions from Thamesmead
Does London parking affect a job in Thamesmead?
London parking can be tight, so details of loading bays and permits help. Night visits tend to make loading easier on London streets.
Which fire and rescue service is responsible for Thamesmead?
Thamesmead is in the area of London Fire Brigade. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Who has the legal duty for fire safety?
The law calls them the responsible person. That’s generally the employer or the person in control of the premises, and where several people have control, each can have duties. If you are not sure, check your lease and fire risk assessment.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and clean down when we finish.
Can you fix a fan that’s worn out?
A fan that needs repair is noted on the report, with what we found. We can repair or replace it, and there’s a 24/7 emergency callout for breakdowns.
What happens on the day
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, 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. For a job in Thamesmead, tell us about loading bays, permits, lifts and roof access when you book.
- We find the fan and check how it’s reached and how it’s isolated.
- With the fan isolated, the housing is opened.
- Grease is scraped from the impeller blades and the inside of the housing.
- We degrease the fan and housing, taking care around the motor.
- It’s closed up, run and checked, and pictures go into your report.
Before we arrive
- Clear the space around the work
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards
Ask for a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Advice
Looking after it afterwards
After the visit, a few habits help the work last:
- Keep access to the fan clear
- Make sure the fan is included each time
- Never cook with a filter missing
- 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.
Listen to the fan. Rattles, hums or shaking can be early signs of build-up or wear, and catching it early keeps it a cleaning job.

Other services in Thamesmead
For landlords and multi-site operators
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
How the job changes from site to site
Impellers and blades
Grease on the leading edges of the blades cuts the fan’s efficiency. We clean each blade back to its surface, so the fan can run as intended.
Roof-mounted fans
Grease can escape from a roof fan onto the surrounding surface and we check the area around the outlet. We note any grease around the fan.
What extract fan cleaning looks like in Thamesmead
Food Standards Agency records list about 46 cafés, restaurants and staff canteens and about 31 sandwich bars and takeaways within 1.5 miles or so of the middle of Thamesmead. Any of those kitchens with a canopy relies on a fan that gathers grease as it runs. Most London extract cleaning happens at night, after the last service. In Thamesmead, food businesses are inspected by environmental health officers from Greenwich 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.
Eastbury Manor House, about 2.4 miles north-west, is one of the historic houses near Thamesmead; if you run event catering at a venue like that, cleans can be booked between functions. A hospital like Erith and District Hospital, about 2.6 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. A hall kitchen that only cooks for events, whether near St Paul or elsewhere in Thamesmead, still needs its extract cleaned, just less often.
