Grease, kitchens and Isleworth
The FSA’s data shows about 65 pubs and bars and about 13 hotels, B&Bs and guest houses registered across Isleworth and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. It’s Hounslow council that sends environmental health officers to food businesses in Isleworth. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after photos from each clean are a simple way to show the extract is in hand. Isleworth sits within the area of London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
If you run a church or community hall kitchen, near Church of All Saints or elsewhere in Isleworth, its extract still collects grease from every lunch and event. For kitchens close to Isleworth station, where the day often starts early and ends late, the extract can be cleaned overnight.

Ductwork cleaning in Isleworth, done properly
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with each certificate issued through the BESCA portal. The work covers attenuators, access panels and bends and junctions, and common reasons people get in touch are a rancid smell from the extract duct and ductwork that has never been cleaned.
In London, few kitchens can spare a day to close, so work in Isleworth is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What affects the quote in Isleworth
There’s no set price list, because no two systems are the same. The quote depends on:
- Site requirements such as sign-in and permits
- The condition we find in the survey
- One-off work versus a regular cycle
- When the work can happen, such as evenings, overnight or weekends
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. Call for a fixed quote and we’ll explain each part.
Asking for a quote
When you contact us, it’s useful to have:
- Your last certificate, test record or report
- The roof, plant room or outside wall the system runs to
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Honest limits
Before booking, it helps to know what’s not included:
- Parts of the duct with no way in
- Undersized or badly laid-out ducts
- Fire dampers that don’t close (they need testing and remedials)
If in doubt, phone us on 0345 646 2711 or use the quote form and we will say what we think.

Questions from Isleworth
Can you come to Isleworth after we close?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Isleworth needn’t be disturbed. When you give us a ring on 0345 646 2711 or use the quote form, mention when the site is quiet.
Who is the fire and rescue service for Isleworth?
London Fire Brigade is the fire and rescue service for Isleworth. 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 happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We don’t leave it behind.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we’re fully insured.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Ring any time and tell us what’s happened.
What should I send you?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply call 0345 646 2711, or send details by email.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
What happens on the day
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a few hours for a short run, longer for long runs and tall risers. Most London sites cannot stop for the day, so work in Isleworth is usually done overnight, early in the morning or at weekends.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- Each section is cleaned in turn through its access panel.
- Bends, risers and the base of each riser get extra attention.
- The duct is signed off with readings, pictures and a next clean date.
How to prepare
- Clear loose items from the work area
- Arrange a key holder or contact on site
- Let us know about permits to work or site inductions
Getting a quote
For a fixed quote, call 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
Advice
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
How the job changes from site to site
Multi-storey and shared buildings
Ducts in taller or shared buildings often run past other occupiers. We plan access with you and the building manager, so the clean is done safely and quietly.
Attenuators and discharge
Attenuators, where fitted, quieten the extract, and their linings can soak up grease. They’re cleaned where possible and recorded if not.
What we are called out for in Isleworth
Slow air leaves the most grease behind. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
What we are most often called out for:
- An insurer asking for TR19 evidence
- Grease pooling at the foot of the riser
- A rancid smell from the extract duct
- Grease seeping out of the duct seams
A hospital like West Middlesex University Hospital, about within half a mile north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
What your quote should include
- What happens if part of the system can’t be accessed
- Whether the quote shows VAT
- What insurance they carry
- Whether the price is fixed
Why it’s worth doing now in Isleworth
BESA guidance says grease shouldn’t exceed a mean of 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean right away. Putting off the clean only pushes readings higher. Leaving it on a busy London site only adds to the work.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.
