What the work involves, part by part
School, care home and staff kitchens
For kitchens closed in the holidays, visits can be timed around term or rota, keeping the filters ready for the busy weeks.
The plenum
Behind the filters sits the plenum, where air gathers before the duct. It collects whatever grease the filters miss.
Grease filter exchange in Walsworth, done properly
Grease filters are the first line of defence in a kitchen extract. They catch grease before it reaches the plenum and ductwork, but only while they’re reasonably clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. If you are dealing with damaged filters letting grease past and filters left unwashed on busy weeks, we can help, from restaurants and pubs, wall canopies and island canopies onwards.
For a smaller kitchen near Walsworth, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

How the visit works
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. A site near Walsworth typically has room to park, so the questions are about access to the system and your hours.
- We look at the canopies and the condition of the filters.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
Before we arrive
- Tell us about site rules, permits or sign-in
- Let us know when the site is closed or quiet
- Mention any parking or loading restrictions
Getting a quote
For a fixed quote, give us a ring on 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.

What affects the quote in Walsworth
There’s no set price list, because no two systems are the same. The quote depends on:
- Whether we need access equipment or extra panels
- Whether several sites go on one quote
- Parking and loading at the site
- How big the system is
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, call us on 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.
Asking for a quote
To speed up the quote, please include:
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Wide photos of the system and the area around it
- How we’d reach plant on a roof or in a plant room
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price, before work begins.
Grease filter exchange around Walsworth
Food Standards Agency data counts about 97 restaurants, cafés and canteens and about 37 takeaways and sandwich shops across Walsworth and its immediate surroundings (about a mile and a half). Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. The fire and rescue service for Walsworth is Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Environmental health officers from North Hertfordshire council inspect food businesses in Walsworth. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
School kitchens, at schools like Highover Junior Mixed and Infant School for example, are usually cleaned in the holidays so no lunches are lost. A hospital like Lister Hospital, about 2.9 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Church and community hall kitchens, near St Faith's Church or anywhere around Walsworth, are easy to forget, but their extracts collect grease like any other.

Your questions about grease filter exchange in Walsworth
Can you get to a site in Walsworth?
Yes. Villages and rural sites across the South East are part of our work, Walsworth included. A survey first, from photos or a visit, means we arrive with the right kit.
Can a school canteen extract in Walsworth be done out of term time?
Yes, out-of-term visits are normal for schools. There are about 22 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Walsworth. You can call 0345 646 2711 or drop us a line with the dates the site is empty.
Will you tell us when the next visit is due?
Yes. We put a recommended next date on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, while fire dampers are tested at least annually.
Are you fully insured?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
Is filter exchange enough instead of a full extract clean?
It does not. Some grease passes the filters as vapour and settles in the ducts, so the full system still needs cleaning to TR19.
Which kinds of sites do you work on?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What does TR19 mean?
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 isn’t legislation, but it’s the standard people check against.
When it’s something else
We will always give you a straight diagnosis, so here’s what this work cannot put right:
- Greasy ducts and risers that a filter change won’t reach
- A canopy too small for the cooking beneath it
- A fan that’s failing or too weak for the system
If you’re not sure, just ring 0345 646 2711 or use the quote form and we will give you a straight answer before booking.

In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Leave it or put it right?
Dripping canopies and greasy smells often start with the filters. Drips land on surfaces and equipment below, which an EHO may well notice. A site near Walsworth that has to close at short notice is hard to cover for.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.

Landlords, agents and facilities managers
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
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.
