Grease filter exchange in Warnham, done properly
Washing filters in the kitchen sink is messy and easily missed on a busy week. An exchange service means clean filters arrive and greasy ones leave, so the canopy is never left without filters. We’re often asked to deal with gaps where filters have been removed and grease collecting in the filter channels, across restaurants and pubs, island canopies and mesh filters.
Work in a small place like Warnham starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Duct Doctor has been trading since 2009, and we’re 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.

Grease filter exchange around Warnham
Food Standards Agency records include about 3 pubs and bars within 1.5 miles or so of the middle of Warnham. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. West Sussex Fire and Rescue Service covers Warnham. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Kitchens in Warnham get their food hygiene inspections from Horsham council. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you look after a school kitchen, at a school such as Warnham CofE Primary School or anywhere near Warnham, the holidays are the usual time for a TR19® clean.

Related advice
Warnham: your questions answered
Can you work in Warnham outside opening hours?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Warnham needn’t be disturbed. Your opening times are the first thing we ask for.
Which environmental health team covers Warnham?
The local authority for Warnham is Horsham council, and its environmental health team does the inspecting. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Do we lose a day’s trading?
Not normally. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits so parts stay in use.
How do you keep the site clean during the work?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
What paperwork should we keep on file?
Anything that proves the system is maintained: reports, certificates, photos and your own cleaning or check logs. One maintenance log per site keeps it simple.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
What affects the cost of grease filter exchange
Every site gets its own quote. This is what makes a difference:
- How many systems or sites are involved
- Travel, parking and unloading
- One-off work versus a regular cycle
- Whether we need access equipment or extra panels
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.
Asking for a quote
When you contact us, these details help:
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
- The paperwork from the last visit, if you have it
- Problems your staff have spotted
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.

Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across West Sussex. Larger estates can be phased building by building around the people who use them.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Clear anything stored on or near the canopy
- Report a dripping canopy early
- Keep canopy surfaces wiped down
- Keep the extract on whenever the range is in use
Nothing changes for your staff, except one less greasy job. Just keep the canopy clear for the next visit and let us know of any changes to opening hours.
Filter exchange and TR19 cleaning work best together. A maintenance plan that covers both keeps everything on track.
Different parts, different methods
School, care home and staff kitchens
Visits can be planned around holidays and quieter periods, keeping the filters ready for the busy weeks.
Baffle filters
When baffles fill with grease, less air gets through. Swapping them for a clean set restores it.
When to call us in Warnham
The type of cooking matters. Fryers, grills and woks load filters faster than ovens and steamers, so the right exchange interval varies.
It’s time to book a visit if you see:
- Filters that come out of the sink still dirty
- Weak extraction at the canopy
- Grease collecting in the filter channels
- Filters so greasy the air can barely pass
If you run a church or community hall kitchen, near The Parish Church of St Margaret or elsewhere in Warnham, its extract still collects grease from every lunch and event.
