Grease filter exchange in Crawley, done properly
In Crawley, our filter exchange runs on a schedule set by how much the kitchen cooks. Busy kitchens need changes more often, lighter ones less. We agree the interval with you at the start. The work covers island canopies, baffle filters and restaurants and pubs, and common reasons people get in touch are grease dripping from the canopy and filters left unwashed on busy weeks.
In a place the size of Crawley, the kitchens with extract systems range from takeaways and restaurants to hotel, school and workplace kitchens. BESA’s minimum intervals run from every three months for heavy use to once a year for light use, so the right schedule depends on the kitchen.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Between visits
Once we have finished, these simple steps help:
- Book full TR19 cleans alongside filter changes
- Wipe the outside of the canopy as part of daily cleaning
- Mention it if the kitchen gets busier
- Tell us if a filter is bent or damaged
Once the clean filters are in, the kitchen can cook right away. We take the greasy filters with us for cleaning.
Filter exchange and TR19 cleaning work best together. A maintenance plan that covers both means neither slips.
What we do, step by step
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. In Crawley, bigger jobs are often split over several out-of-hours visits.
- First, we record the size, type and number of filters in each canopy.
- Together we set how often the filters should be changed.
- Each visit starts with the used filters being removed.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Tell us where we can park and unload
- Clear the space around the work

Questions from Crawley
Who would carry out a food hygiene inspection at a kitchen in Crawley?
That’s Crawley council, whose environmental health officers carry out food hygiene inspections in Crawley. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you clean school kitchen extracts in Crawley during the holidays?
Yes, holiday work suits schools best. Around Crawley, the Food Standards Agency lists about 23 schools and colleges with registered kitchens within a mile and a half or so. You can call 0345 646 2711 or email us with the dates the site is empty.
Does a filter exchange replace TR19 cleaning?
No. The rest of the system still collects grease at the right interval.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
What happens if you cannot reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Will I get paperwork for my records?
Yes. It’s the record insurers and inspectors ask to see: a written, dated record with photos of what we did and anything we couldn’t access.
Do we need to close the kitchen while filters are changed?
An exchange does not take long, and can be booked outside service times. There’s no wait between removing and refitting.
Can you look after several sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.

What we’re called out for in Crawley
Cooking vapour carries grease into the canopy. Much of it is trapped by the filters, and day by day they load up until the air can barely get through.
Clients usually contact us after spotting one of these:
- Filters so greasy the air can barely pass
- Staff short of time to wash filters
- Grease left in baffles after washing
- Grease collecting in the filter channels
Bursars and site managers at schools such as Three Bridges Junior School tend to book extract cleaning for when the kitchen is empty.
Before you book anyone
- Which accreditations they hold, and whether you can check them
- When they can work, and whether that’s outside your opening hours
- Whether they’re fully insured
- How they set the interval to the next visit
What happens if it’s left?
Once filters are saturated, more grease gets past them. The ductwork then loads up faster and grease readings can rise between cleans. We can set up 3, 6 or 12-monthly visits so nothing on a site in Crawley gets missed.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before we start.

What the work involves, part by part
The plenum
The plenum is the space behind the filters. It collects whatever grease the filters miss.
Busy restaurant and pub kitchens
High-output kitchens clog filters quickly. Their exchange schedule is typically the tightest.
What staff can safely do
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
What grease filter exchange looks like in Crawley
Food Standards Agency records list about 101 restaurants, cafés and works canteens and about 51 sandwich bars and takeaways across Crawley and its immediate surroundings (about a mile and a half). Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. In Crawley, food businesses are inspected by environmental health officers from Crawley council. 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. The fire and rescue service for Crawley is West Sussex Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Crawley Hospital is the nearest hospital to Crawley, about 0.5 miles north-west. If you run a church or community hall kitchen, near Friary Church of St Francis and St Anthony or elsewhere in Crawley, its extract still collects grease from every lunch and event.
