How we handle grease filter exchange in Dudswell
A filter that does not sit right lets grease straight past. Bent, damaged or missing filters leave gaps and every filter is checked when we swap them. We point out any that need replacing. The work covers wall canopies, restaurants and pubs and school and hospital kitchens, and the jobs we see most are hand-washed filters that still look greasy and filters that leave gaps in the canopy.
In a village or hamlet like Dudswell, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
A written report with photos follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

FAQs for Dudswell
Is Dudswell within the area you cover?
Yes. Dudswell is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Can the work in Dudswell be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The work in Dudswell can fit around your hours. Tell us your opening hours when you ask for a quote.
How long does grease filter exchange take?
It depends on the size of the system, but for a typical site it takes a few minutes per canopy, longer for a large kitchen with several canopies. We’ll confirm it with the quote.
Who has the legal duty for fire safety?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
What happens if you cannot reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
Is filter exchange enough instead of a full extract clean?
It isn’t. Clean filters help keep grease down, but the ducts and plenum still need cleaning at the right interval.
What should go in our maintenance log?
Every certificate and report from each visit, kept together in your maintenance log, along with your own cleaning log. BESA says certificates should show the date, location and technician.
What grease filter exchange looks like in Dudswell
Food Standards Agency records list about 7 restaurants, cafés and works canteens within roughly a mile and a half of the centre of Dudswell. Clogged filters slow the airflow, and busy kitchens like these clog them fast. The fire and rescue service for Dudswell is Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. In Dudswell, food businesses are inspected by environmental health officers from Dacorum council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after photos from each clean are a simple way to show the extract is in hand.
Volunteers running a hall kitchen near Church of Saint Mary, or anywhere in Dudswell, may not know when the extract was last cleaned, and a grease test settles it. School kitchens, at schools like St Mary's CofE Primary School for example, are usually cleaned in the holidays so no lunches are lost. If you run catering at a historic house or estate in the area (Cholesbury Manor House is about 2.7 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning.

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.
Busy restaurant and pub kitchens
Kitchens that fry and grill all day load their filters fast. Their exchange schedule is typically the tightest.

Between visits
After the visit, a few habits help the work last:
- Mention it if the kitchen gets busier
- Look out for drips from the canopy
- Clean the canopy surfaces regularly
- Make sure we can reach the canopy on exchange day
Keep an eye out for filters that have been taken out. Gaps let grease into the plenum so tell us if you need a replacement.
Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking, and it’s worth checking the plenum too.
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Why it’s worth doing now in Dudswell
A filter exchange is a few minutes; a choked extract affects a whole service. It’s one of the simplest parts of looking after the system and few are as easy to forget. Planning a trip to Dudswell ahead is easier for everyone than a rushed one.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before work begins.

What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit 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 Dudswell, let us know and we’ll plan around it.
- First, we record the size, type and number of filters in each canopy.
- We agree a schedule that suits how much the kitchen cooks.
- On each visit, the dirty filters come out of the canopy.
- 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.
