West Sussex · Grease filter exchange
Grease filter exchange in Ashurst, West Sussex
Our technicians work in Ashurst on a scheduled grease filter exchange, swapping dirty canopy filters for clean ones. Out-of-hours visits, a fixed quote and a written report with photos as standard.
- Gaps where filters have been removed
- Filters that leave gaps in the canopy
- Grease dripping from the canopy
How the job changes from site to site
The plenum
Heavy grease in the plenum often follows clogged or missing filters, or that a full clean is due.
Mesh filters
Older or smaller canopies often use mesh filters. They can be on the same exchange schedule as baffle filters.
About our grease filter exchange in Ashurst
We set up grease filter exchange for kitchens in Ashurst on a schedule that suits their cooking. The heavier the cooking, the more often filters need changing while a lighter kitchen can go longer. The interval is agreed before the first visit. If you are dealing with staff short of time to wash filters and weak extraction at the canopy, we can help.
In a village or hamlet like Ashurst, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
Every visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What affects the quote in Ashurst
The quote reflects the site in front of us. We consider:
- Where the site is and how we reach it
- Any permits to work or inductions
- Whether it’s a one-off visit or part of a schedule
- How many systems or sites are involved
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
Helping us quote
To speed up the quote, send us:
- The site address and the type of premises
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
- Where the plant sits or the system leaves the building, such as a roof or outside wall
To help us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711 or drop us a line.

What else we do in Ashurst
Common problems we fix in Ashurst
Kitchens in Ashurst, as everywhere, find filter washing slips down the list on busy weeks. A missed wash or two is all it takes for filters to fill with grease.
Clients normally contact us after spotting one of these:
- Poor airflow through the filters
- Filters so greasy the air can barely pass
- A canopy that drips grease
- Grease building up behind the canopy filters
Church and community hall kitchens, near The Parish Church of St James or anywhere around Ashurst, are easy to forget, but their extracts collect grease like any other.
What your quote should include
- Proof of insurance
- Whether the work can be done while the site is closed
- If they look at the system before pricing
- Whether the price is fixed
Questions from Ashurst
Do you work overnight in Ashurst?
Yes, nights and weekends are routine for us. It means the site in Ashurst keeps running as normal. When you call 0345 646 2711 or drop us a line, mention when the site is quiet.
Which environmental health team covers Ashurst?
In Ashurst, it’s Horsham council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
What if some of our filters are damaged?
Filters that no longer fit properly need replacing. We will show you which ones on the visit.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Is filter exchange enough instead of a full extract clean?
No, the two work together. A TR19® clean deals with the whole system and comes with a certificate and photo report.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
What’s the right interval for changing filters?
It varies with the type and amount of cooking. If filters are dripping or clogging before the next change, it’s too long and we’ll adjust it.
Do we need to close while you work?
Not usually. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits to keep things running.
What we do, step by step
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the grease filter exchange, clear away and hand over the paperwork. On site, the work takes less than an hour in most kitchens. Seeing the system in photos first means the trip to Ashurst can be planned properly.
- We start by noting how many filters you have and what type they are.
- A change schedule is agreed to match the kitchen’s cooking hours.
- At each visit, the greasy filters are lifted out.
- Clean filters go straight back in, seated properly with no gaps.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about permits to work or site inductions
Ask for a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.
Advice
For landlords and multi-site operators
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
When it’s something else
We won’t sell you work that does not address the problem, so these are the things it will not cover:
- Greasy ducts and risers that a filter change will not reach
- Smell complaints that need odour control equipment
- Grease behind the filters that a swap cannot remove
Not sure which it is? You can ring 0345 646 2711, or send details by email and we will tell you honestly.

What grease filter exchange looks like in Ashurst
West Sussex Fire and Rescue Service covers Ashurst. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. It’s Horsham council that sends environmental health officers to food businesses in Ashurst. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Bursars and site managers at schools such as Ashurst CofE Primary School tend to book extract cleaning for when the kitchen is empty.
