How we handle grease filter exchange in Pirbright
Whether your canopy has baffle or mesh filters, they load up with grease. Clogged filters choke the airflow and the fan has to work harder. Regular exchange keeps the air moving. Common call-outs are for grease collecting in the filter channels and missing filters in the filter bank, across wall canopies, mesh filters and baffle filters.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes anything from a few minutes to an hour or so, depending on the number of filters. If the van will struggle with a lane or gateway near Pirbright, let us know and we will plan around it.
- We count and measure the filters in every canopy.
- We agree a schedule that suits how much the kitchen cooks.
- On each visit, the dirty filters come out of the canopy.
- Clean filters go straight back in, seated properly with no gaps.
- If a filter is damaged or the plenum needs attention, we tell you.
Preparing for the visit
- Let us know about parking and loading
- Arrange a key holder or contact on site
- Have your last certificate or report to hand
Ask for a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

When it’s something else
We will not sell you work that does not address the problem, so these are the things it won’t cover:
- Odours from the discharge that filters won’t stop
- A canopy that does not capture the vapour properly
- Grease deep in the extract system
If you are not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer.

How the job changes from site to site
Mesh filters
Mesh traps grease between its layers, which makes hand-washing hard work.
School, care home and staff kitchens
Lighter kitchens can often go longer between changes. We agree the schedule to match.
Landlords, agents and facilities managers
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.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Pirbright: your questions answered
Do you cover smaller places like Pirbright?
Yes, Pirbright is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Which fire service covers Pirbright?
That’s Surrey Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Can you give a price for filter changes?
The cost depends on your filters and the schedule. We’ll give you a fixed quote, usually within one working day.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and waste is contained as we go. Before we leave, we tidy up and clean down.

Grease filter exchange around Pirbright
Food Standards Agency records list about 9 restaurants, cafés and canteens and about 3 sandwich bars and takeaways within roughly a mile and a half of the centre of Pirbright. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Pirbright sits within the area of Surrey Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Kitchens in Pirbright get their food hygiene inspections from Guildford council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.
A hospital like Brookwood Hospital, about 1.9 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Commuter trade near Brookwood station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Always run the extract while cooking
- Tell us if the menu or opening hours change
- Don’t refit a filter that’s bent
- Keep filter exchange and TR19 cleaning on the same plan
Fresh filters improve airflow at the canopy from the moment they’re fitted. Keep the extract running while you cook so they catch grease as intended.
Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.
