About our grease filter exchange in Brasted Chart
An exchange visit in Brasted Chart doesn’t take long. The greasy filters come out, clean ones go in, and we check they’re seated with no gaps. If something looks wrong, we tell you. The work covers mesh filters, baffle filters and restaurants and pubs, and people most often call us about a greasy plenum behind the filters and blocked baffle filters.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Brasted Chart, that normally means a longer system to clean and more access panels to plan around.
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’re fully insured.

What grease filter exchange looks like in Brasted Chart
There are about 16 restaurants, cafés and works canteens in Brasted Chart and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Clogged filters slow the airflow, and busy kitchens like these clog them fast. London jobs usually start after the last service, with loading and roof access agreed with the building first. Food hygiene inspections in Brasted Chart are the job of Sevenoaks council’s environmental health team. 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.
Quebec House, about 1.2 miles west, is one of the historic houses near Brasted Chart; if you run event catering at a venue like that, cleans can be booked between functions.

How the visit works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before we start, and floors and nearby surfaces are sheeted. On site, it takes less than an hour in most kitchens. For a job in Brasted Chart, tell us about loading bays, permits, lifts and roof access when you book.
- First, we record the size, type and number of filters in each canopy.
- A change schedule is agreed to match the kitchen’s cooking hours.
- On each visit, the dirty filters come out of the canopy.
- We fit clean filters and check they sit snugly in the housing.
- If a filter is damaged or the plenum needs attention, we tell you.
How to prepare
- Have your last certificate or report to hand
- Name a contact who can let us in at the agreed time
- Mention any parking or loading restrictions
Ask for a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.

Aftercare tips
Think of this as the after-treatment advice, in brief:
- Keep every filter in place during service
- Report a dripping canopy early
- Make sure we can reach the canopy on exchange day
- Tell us if a filter is bent or damaged
Nothing changes for your staff, except one less greasy job. Just keep the canopy clear for the next visit and tell us if service times change.
If filters are already dripping, they’re overdue. A clean set right away cuts the grease in the canopy, and it’s worth checking the plenum too.

Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
What happens if it’s left?
Leaving filters too long pushes more grease into the plenum and ducts. That makes the next full clean a bigger job, and grease may build up faster than the cleaning interval allows. A building in Brasted Chart may have flats or offices above and alongside, and a fault in the system can affect them too.
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 you get with us
- Evenings, overnight and weekends, plus 24/7 emergency callout
- A written report with photos after every visit
- Accredited under CHAS and SafeContractor, with ISO 9001
- One contact for all your sites in London and the South East

Brasted Chart: your questions answered
Who enforces fire safety at workplaces in Brasted Chart?
London Fire Brigade is the fire and rescue service for Brasted Chart. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you do school kitchen extract cleaning in Brasted Chart in the summer holidays?
Yes, out-of-term visits are normal for schools. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Brasted Chart, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
What do you do with what you remove?
We take it away when we go. During the work, it’s contained so the area stays clean.
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 where they can be found quickly.
Do you provide a certificate or report?
Yes, on every job. The report is dated and includes photos, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. Keep it in your maintenance log.
Does a filter exchange disrupt service?
Visits are short, and can be booked outside service times. There’s no wait between removing and refitting.
What if some of our filters are damaged?
A bent filter leaves a gap for grease. We point them out on the visit so they can be replaced.
Where do the greasy filters go?
We take them away to be cleaned, so your staff do not have to wash them. Clean filters go straight in.
What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
When something else is needed
Not every problem is solved by grease filter exchange, and we will tell you before we start. It won’t put right:
- A canopy that does not capture the vapour properly
- Odours from the discharge that filters will not stop
- A heavily greased plenum or canopy, which needs cleaning to TR19
Not sure which it is? You can ring 0345 646 2711, or email photos and we will tell you honestly.
Where we work
- Mesh filters
- Restaurants and pubs
- Wall canopies

Part by part
Canopy filter housings
Grease collects in the channels and drip trays below the filters. We point it out if it needs cleaning.
The plenum
Heavy grease in the plenum often follows clogged or missing filters or that the next TR19 clean is due.
