Different parts, different methods
Mesh filters
Mesh filters are still found in many canopies. They can be on the same exchange schedule as baffle filters.
Baffle filters
Baffle filters are a common choice for commercial canopies. They don’t clean themselves, because the grease they collect builds up.
About our grease filter exchange in Dartmouth Park
Cleaning filters by hand takes staff time and is easy to put off. With a filter exchange, we bring a clean set and take the dirty one away and the canopy is refilled right away. We are often asked to deal with a canopy that drips grease and weak extraction at the canopy, across island canopies, restaurants and pubs and wall canopies.
In London, few kitchens can spare a day to close, so extract cleaning in Dartmouth Park is normally done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What we’re called out for in Dartmouth Park
The type of cooking matters. Fryers, grills and woks load filters faster than ovens and steamers, so the right exchange interval varies.
These are the problems we see most often:
- Filters so greasy the air can barely pass
- Filters that leave gaps in the canopy
- Staff short of time to wash filters
- Grease building up behind the canopy filters
If you run catering at a healthcare site, such as a hospital like Royal Northern Hospital about 0.8 miles east, the extract may need cleaning more often than a part-time kitchen.
Before you book anyone
- Whether VAT is included
- If the quote is a fixed price or an estimate
- Whether they’re fully insured
- Exactly which parts of the system are covered
Aftercare tips
To keep the system working properly between visits:
- Don’t refit a filter that is bent
- Make sure no filter is left out
- Never cook with the extract switched off
- Clear anything stored on or near the canopy
The canopy looks cleaner and the air moves better straight away. Always run the extract during cooking so they catch grease as intended.
Bent or missing filters let grease straight past. Sorting them now keeps grease where it can be caught.

For landlords and multi-site operators
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
What grease filter exchange looks like in Dartmouth Park
The FSA’s food hygiene register shows about 636 cafés, restaurants and staff canteens and about 305 takeaways within 1.5 miles or so of the middle of Dartmouth Park. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Environmental health officers from Camden council inspect food businesses in Dartmouth Park. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready. Dartmouth Park 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.
Volunteers running a hall kitchen near Church of St Mary Brookfield, or anywhere in Dartmouth Park, may not know when the extract was last cleaned, and a grease test settles it. If you look after a school kitchen, at a school such as Acland Burghley School or anywhere near Dartmouth Park, the holidays are the usual time for a TR19® clean.

What your team can do, and what needs us
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.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Dartmouth Park questions

Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. If the building has a loading slot system, we’ll book into it.

Do you survey before quoting?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.

The common types of grease filter: baffle and mesh. Tell us what you have when you call us on 0345 646 2711 or send us an email and we will confirm it on site.

Do you recommend a next date?
Yes. Every report includes a recommended date for the next visit, based on use and what we found.
How we price grease filter exchange
The diagnosis comes before the price. The main factors are:
- Whether several sites go on one quote
- Whether we need access equipment or extra panels
- The condition we find in the survey
- Travel, parking and unloading
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, call 0345 646 2711 or drop us a line for straight advice and a fixed quote.
Asking for a quote
We can often survey from pictures. Try to include:
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
- Any symptoms, from odd noises to smells or leaks
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. Add the site type and your opening hours, and we can price many jobs without a visit.
What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes anything from a few minutes to an hour or so, depending on the number of filters. A name and number for whoever controls access to the building in Dartmouth Park saves time on the night.
- First, we record the size, type and number of filters in each canopy.
- We agree a schedule that suits how much the kitchen cooks.
- At each visit, the greasy filters are lifted out.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- If a filter is damaged or the plenum needs attention, we tell you.
How to prepare
- Clear loose items from the work area
- Have your last certificate or report to hand
- Tell us about site rules, permits or sign-in
