About our grease filter exchange in Lessness Heath
We run grease filter exchange for all kinds of kitchens in Lessness Heath, whether there’s one canopy or many. We can come before or after service, so cooking is not interrupted. We’re often asked to deal with filters that come out of the sink still dirty and missing filters in the filter bank, on island canopies, baffle filters and wall canopies.
In London, few kitchens can spare a day to close, so work in Lessness Heath 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.
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 carry full insurance.

How it works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes well under an hour for most canopies, and we clear up before we go. If your building in Lessness Heath has sign-in rules, permits or key holders, mention them when you book.
- The filters in each canopy are measured and counted.
- An exchange schedule is agreed to suit your cooking.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- We take the greasy set away and confirm the next date.
Preparing for the visit
- Find the previous report, if there is one
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards
How to get a quote
Photos are enough for some jobs, while others need a look on site. 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.

Grease, kitchens and Lessness Heath
Food Standards Agency data counts about 62 restaurants, cafés and canteens and about 74 takeaways across Lessness Heath and its immediate surroundings (about a mile and a half). Each canopy among them has filters that load with grease and need swapping or cleaning. Lessness Heath sits within the area of London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. It’s Bexley council that sends environmental health officers to food businesses in Lessness Heath. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Erith and District Hospital is the nearest hospital to Lessness Heath, about 0.9 miles south-east. For kitchens close to Belvedere station, where the day often starts early and ends late, the extract can be cleaned overnight. A hall kitchen that only cooks for events, whether near Parish Church of All Saints or elsewhere in Lessness Heath, still needs its extract cleaned, just less often.

Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Clean the canopy surfaces regularly
- Keep the extract on whenever the range is in use
- Never leave gaps in the filter bank
- Book full TR19 cleans alongside filter changes
Between visits, check that every filter is still in place. A missing filter leaves a gap for grease so tell us if you need a replacement.
If filters are already dripping, they’re overdue. A clean set straight away cuts the grease in the canopy, and it’s worth checking the plenum too.
Staff cleaning versus specialist work
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Lessness Heath questions
How do you handle parking and loading in Lessness Heath?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Which fire and rescue service is responsible for Lessness Heath?
It’s London Fire Brigade, which covers Lessness Heath. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
Do we need to close the kitchen while filters are changed?
A filter change is quick and can be timed around service. The canopy shouldn’t be used without filters so the swap is done promptly.
Which grease filters does the service cover?
We exchange baffle and mesh filters. We record the sizes and number of filters at the start so the clean set always fits.
Do you work in Lessness Heath?
Yes. Our technicians work in Lessness Heath, within the South East and London area we cover.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.

What else we do in Lessness Heath
Honest limits
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- Grease already built up in the ductwork, which needs a full TR19 clean
- A canopy that needs a proper clean
- A fan that’s failing or too weak for the system
If you’re not sure, just phone us on 0345 646 2711 or use the quote form and we will give you a straight answer before you book.
Parts of the system we cover
- Restaurants and pubs
- Baffle filters
- Island canopies
- Mesh filters
- School and hospital kitchens
- Wall canopies
How the job changes from site to site
School, care home and staff kitchens
Even kitchens with fixed meal times build up grease though normally at a gentler pace.
Baffle filters
Baffle filters are a common choice for commercial canopies. They don’t clean themselves as the collected grease builds up between the blades.
