Why it’s worth doing now in Harmer Green
For any kitchen in Harmer Green, filters can’t stand in for a full TR19 clean. They do help keep the system in better shape between cleans, and that shows when the next clean comes round. Somewhere as small as Harmer Green, losing a kitchen or building to a fault is felt by everyone who uses it.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we will price it together.

Grease filter exchange in Harmer Green, done properly
Across Harmer Green, our filter exchange suits restaurants, pubs, cafés, schools, care homes and other kitchens, from a single canopy to several. Visits can be timed around your service so nobody has to stop cooking. The work covers mesh filters, school and hospital kitchens and wall canopies, and common reasons people get in touch are hand-washed filters that still look greasy and filters that leave gaps in the canopy.
In a village or hamlet like Harmer Green, the kitchens that need extract cleaning are typically 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.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What else we do in Harmer Green
Grease filter exchange in Harmer Green: the local picture
The FSA’s food hygiene register shows about 14 restaurants, cafés and canteens across Harmer Green and its immediate surroundings (about a mile and a half). Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. The fire and rescue service for Harmer Green is Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. In Harmer Green, food businesses are inspected by environmental health officers from East Hertfordshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
A hospital like Queen Elizabeth II Hospital, about 3.4 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day. For schools such as Oaklands Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

FAQs for Harmer Green
Do you work in villages like Harmer Green?
Yes, we work in villages as well as towns, and Harmer Green is covered. Let us know about access, parking and anything unusual about getting there when you book.
Who enforces fire safety at workplaces in Harmer Green?
Fire safety enforcement in Harmer Green is handled by Hertfordshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Can we skip TR19 cleans if the filters are changed regularly?
No. The rest of the system still collects grease at the right interval.
What happens to the waste?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
Does a filter exchange disrupt service?
A filter change is quick and can be timed around service. Cooking shouldn’t happen with the filters out, so we swap them in one go.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
Do you recommend a next date?
Yes. The recommended date is 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, and fire dampers need testing at least once a year.
What should go in our maintenance log?
Everything that shows the system is looked after: our reports and pictures, any certificates and your in-house logs. One maintenance log per site keeps it simple.
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
What we are called out for in Harmer Green
What a kitchen cooks affects how fast filters clog. Fryers, grills and woks load filters faster than ovens and steamers, so the right exchange interval varies.
Clients usually contact us after spotting something like this:
- A canopy that drips grease
- Grease collecting in the filter channels
- A canopy running with filters missing
- Grease left in baffles after washing
If you run a café or takeaway near Welwyn North station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
Before booking anyone
- How they set the interval to the next visit
- Whether a written report and pictures are included
- What’s included in the scope, part by part
- Whether a survey comes first
What a clean won’t put right
It’s worth knowing the limits before booking:
- Grease already built up in the ductwork, which needs a full TR19 clean
- Odours from the discharge that filters won’t stop
- A canopy that needs a proper clean
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we’ll tell you honestly.

The process
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, and that takes a short visit, depending on how many filters the canopies hold. For a village or hamlet like Harmer Green, tell us about narrow lanes, gates and parking when you book.
- 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.
- The filters are checked for fit before we go.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Preparing for the visit
- Tell us where we can park and unload
- Clear the space around the work
- Tell us the best time to work, such as after service or at a weekend
How to get a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
