About our grease filter exchange in Cowfold
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 and the canopy is refilled right away. The work covers mesh filters, baffle filters and restaurants and pubs, and common reasons people get in touch are weak extraction at the canopy and a canopy running with filters missing.
In a small place like Cowfold, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Cowfold: your questions answered
Which fire service covers Cowfold?
Fire safety enforcement in Cowfold is handled by West Sussex Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you work at weekends in Cowfold?
Yes. We work evenings, overnight and at weekends. It means the site in Cowfold keeps running as normal. Let us know the hours you are closed and we will book within them.
Who has the legal duty for fire safety?
In the words of the Fire Safety Order 2005, it’s the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.
Do you handle baffle and mesh filters?
We exchange baffle and mesh filters. We record the sizes and number of filters at the start so every set we bring fits.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What’s the right interval for changing filters?
There’s no single answer. We look at your cooking and set an interval to match, and adjust it if needed.
Do you take the used filters away?
They leave with us. That’s how an exchange works: clean filters in, dirty ones out and nothing greasy left on site.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Fixed quotes for grease filter exchange in Cowfold
There’s no set price list, because no two systems are the same. The quote depends on:
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- The condition of the system
- Travel, parking and unloading
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before work begins.
What to send for a quote
We can often survey from pictures. Try to include:
- Wide photos of the system and the area around it
- Where the site is and what kind of site it is
- Your opening hours and when the area is out of use
- Any access panels or hatches you can see
Want a quote for grease filter exchange? Please call 0345 646 2711 or send us an email and tell us about the site. We will talk you through the work and give you a fixed quote before anything is booked.
Between visits
Simple habits between visits make a real difference. Our advice:
- Clear anything stored on or near the canopy
- Keep the extract on whenever the range is in use
- Tell us if a filter is bent or damaged
- Tell us if the menu or opening hours change
If the plenum behind the filters looks greasy, we say so. It can be a sign that a full TR19® clean is due, and we can arrange it.
Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner between full cleans.
Why act early in Cowfold
In Cowfold, as everywhere, a filter service isn’t a substitute for TR19 cleaning. But clean filters do help the system between cleans, and that shows when the next clean comes round. Planning a trip to Cowfold ahead is easier for everyone than a rushed one.
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’ll price it together.

If in doubt, call us on 0345 646 2711 or drop us a line and we will say what we think before you book.

Landlords, agents and facilities managers
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Grease, kitchens and Cowfold
It’s Horsham council that sends environmental health officers to food businesses in Cowfold. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Cowfold is about 36 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible.
For schools such as St Peter's CofE (Aided) Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. If you run catering at a healthcare site, such as a hospital like The Dene Hospital about 4.9 miles east, the extract may need cleaning more often than a part-time kitchen.

When to call us in Cowfold
Missing filters are more common than you’d think. Every gap in the filter bank lets grease straight into the plenum where it settles out of sight.
What we’re most often called out for:
- Filters that leave gaps in the canopy
- Filters so greasy the air can barely pass
- Weak extraction at the canopy
- Grease collecting in the filter channels
Where a hall near Church of St Peter, or anywhere in Cowfold, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Questions to ask before you book
