Grease filter exchange in Heston
We set up grease filter exchange for kitchens in Heston on a schedule that suits their cooking. The heavier the cooking, the more often filters need changing, lighter ones less. The interval is agreed before the first visit. Common call-outs are for bent or damaged filters that don’t sit properly and filters so greasy the air can barely pass, across mesh filters, school and hospital kitchens and wall canopies.
Kitchens in Heston, 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. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is 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 they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a few minutes per canopy, longer for a large kitchen with several canopies. Loading bays, visitor permits and roof access are the first things we ask about for a site in Heston.
- First, we record the size, type and number of filters in each canopy.
- We agree a schedule that suits how much the kitchen cooks.
- On each visit, the dirty filters come out of the canopy.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- We flag any damaged filters or anything wrong with the canopy.
How to prepare
- Mention any parking or loading restrictions
- Mention any sign-in, permit or induction we need
- Let us know how we reach the system, including roofs, risers and plant rooms
Getting a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.

What affects the quote in Heston
Sites vary more than people expect. What affects the quote:
- Any permits to work or inductions
- How big the system is
- How easy every part is to reach
- The condition of the system
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before work begins.
What we need to know
Photos let us diagnose from a distance. Try to include:
- Any access panels or hatches you can see
- A few general shots of the system
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, and then give you a fixed quote. To get going, call 0345 646 2711 or drop us a line.

Not every problem is solved by grease filter exchange, and we will tell you before any work starts. It won’t put right:
- A heavily greased plenum or canopy, which needs cleaning to TR19
- Extraction problems caused by the fan rather than the filters
- Grease deep in the extract system
If you are not sure, just give us a ring on 0345 646 2711, or email photos and we will give you a straight answer.

Common questions in Heston
Can the work in Heston be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. It means the site in Heston keeps running as normal. Your opening times are the first thing we ask for.
Is parking a problem for work in Heston?
London parking can be tight, so details of loading bays and permits help. If the building has a loading slot system, we’ll book into it.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
What should go in our maintenance log?
Visit reports, certificates and your in-house cleaning logs. Insurers, fire officers and EHOs may all ask to see them, so keep them together and easy to find.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Call us any time and explain what’s happened.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
How long will you be on site?
The work itself takes anything from a few minutes to an hour or so, depending on the number of filters. Bigger or more complicated systems take longer, and the quote will say how long.
Which grease filters does the service cover?
Baffle and mesh filters are both covered. The first step is recording what you have and set up the service around them.
Grease, kitchens and Heston
Food Standards Agency records list about 275 restaurants, cafés and works canteens and about 124 takeaways in and around Heston, up to about a mile and a half out. Clogged filters slow the airflow, and busy kitchens like these clog them fast. In London, kitchens are normally cleaned overnight, when the kitchen is closed and loading is easier. Environmental health officers from Hounslow council inspect food businesses in Heston. 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.
Bursars and site managers at schools such as Westbrook Primary School tend to book extract cleaning for when the kitchen is empty. Healthcare kitchens, like those at hospitals such as Hounslow Hospital (about 1.2 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.
Heston is about 2 miles south of Southall, in Greater London. Whether your site is in the middle of Heston or further out, grease filter exchange is available to all kinds of commercial premises, from small sites to large estates. Heston is one of 764 places in Greater London we cover for commercial clients. You can also see our page for London, roughly 12 miles from Heston.

Near you in Heston
Locally, jobs take us to businesses close to Inwood Park, The Plough Public House and Heston Community School and the streets around them. The nearest railway station is Southall station, roughly 1.4 miles north. Nearby you will also find Museum of Army Music (2.4 miles south-east) and Treaty Centre (1.3 miles south-east). Open spaces near Heston include Northala Fields and Crane Meadows.
When to call us in Heston
The type of cooking matters. Fryers, grills and woks load filters faster than ovens and steamers, so the right exchange interval varies.
Look out for any of the following:
- Gaps where filters have been removed
- Hand-washed filters that still look greasy
- A greasy plenum behind the filters
- Smoke and heat lingering under the hood
If you run a church or community hall kitchen, near St Leonard's Church or elsewhere in Heston, its extract still collects grease from every lunch and event.
Questions to ask before you book
- Whether they recommend a next date
- Whether a survey comes first
- Whether the quote shows VAT
- Proof of insurance
Why act early in Heston
In Heston, as everywhere, a filter service isn’t a substitute for TR19 cleaning. They do help keep the system in better shape between cleans and the canopy and plenum stay cleaner. In Heston, a planned overnight visit is much easier than closing unexpectedly.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
Why us?
- Fixed quotes from a survey or photos
- Every visit written up, with pictures

- Out-of-hours work and a 24/7 emergency line

Keeping the system healthy
Once we’ve finished, these simple steps help:
- Watch for grease drips between visits
- Don’t refit a filter that is bent
- Make sure we can reach the canopy on exchange day
- Let us know if your cooking hours increase
Your team carries on as normal, without the filter washing. Just keep the canopy clear for the next visit and let us know of any changes to opening hours.
Bent or missing filters let grease straight past. Sorting them now keeps grease where it can be caught.
