About our grease filter exchange in Datchworth
Good filters only work when they fit properly. Bent, damaged or missing filters leave gaps and every filter is checked when we swap them. We point out any that need replacing. If you have a canopy running with filters missing and grease dripping from the canopy, we can put it right.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Part by part
Mesh filters
Mesh filters are still found in many canopies. We exchange them on the same basis as baffles.
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.
When to call us in Datchworth
Sometimes a filter is taken out and never put back. A missing filter leaves an open route into the system and on into the ductwork.
Any of these means the system needs a check-up:
- A canopy that drips grease
- Filter washing that keeps being missed
- Poor airflow through the filters
- Gaps where filters have been removed
Church and community hall kitchens, near Church of All Saints or anywhere around Datchworth, are easy to forget, but their extracts collect grease like any other.
What your quote should include
- Whether the quote is based on a survey or photos
- How they set the interval to the next visit
- How VAT is shown on the quote
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
Multi-site and managed buildings
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.
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Your questions about grease filter exchange in Datchworth
Can a school canteen extract in Datchworth be done out of term time?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Datchworth. You can ring 0345 646 2711 or send us an email with the dates the site is empty.
Which council inspects kitchens in Datchworth?
Kitchens in Datchworth are inspected by East Hertfordshire council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Will you tell us when the next visit is due?
Yes. Every report includes a recommended date for the next visit, based on use and what we found.
Can damaged filters stay in the canopy?
Filters that no longer fit properly need replacing. We’ll tell you which ones and why when we find them.
Can we book visits on a schedule?
Yes, of course. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
How long will you be on site?
Your quote will say how long we expect to be there. For a typical site, it takes anything from a few minutes to an hour or so, depending on the number of filters.
Do you clean filters as well as exchanging them?
We can. Some kitchens prefer their own filters cleaned on a schedule, and others prefer a straight swap. Either way, the canopy isn’t left without filters during service.
Keeping the system healthy
So the system stays in good health:
- Keep every filter in place during service
- Tell us if the menu or opening hours change
- Keep the canopy clear for exchange visits
- Don’t refit a filter that’s bent
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.
If filters are already dripping, they’re overdue. A clean set straight away cuts the grease in the canopy and the plenum may need a clean as well.
What affects the cost of grease filter exchange
There’s no set price list, because sites vary so much. The quote depends on:
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- Where the site is and how we reach it
- The condition of the system
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.
What to send for a quote
To help us quote quickly, please include:
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
The quickest way to a quote is to send pictures: 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.
What we do, step by step
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before we start, and the area around the work is covered and protected. On site, it takes less than an hour in most kitchens. In a small place like Datchworth, the journey is planned ahead and the visit arranged around the site’s hours.
- The filters in each canopy are measured and counted.
- We set the interval with you.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- The dirty filters leave with us and the next visit is booked.
How to prepare
- Dig out any earlier paperwork for the system
- Let us know when the site is closed or quiet
- Clear the space around the work
