Different parts, different methods
Mesh filters
Layers of mesh catch grease droplets. In a busy kitchen, mesh soon blocks, so they need changing often.
The plenum
The plenum is the space behind the filters. It collects whatever grease the filters miss.
Grease filter exchange for kitchens and businesses in Childwick Green
Good filters only work when they fit properly. Bent, damaged or missing filters leave gaps and every filter is checked when we swap them. Damaged filters are flagged so they can be replaced. Typical jobs include filters that leave gaps in the canopy and a greasy plenum behind the filters, on school and hospital kitchens, restaurants and pubs and baffle filters.
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.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

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.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Do you need grease filter exchange in Childwick Green?
Wherever you are, Childwick Green included, filter washing is the job that gets skipped when the kitchen is busy. It only takes a couple of missed weeks for a filter bank to clog.
Signs it’s time to call us include:
- Grease filters clogged with grease
- Grease collecting in the filter channels
- Staff short of time to wash filters
- Missing filters in the filter bank
Healthcare kitchens, like those at hospitals such as St Albans City Hospital (about 1.6 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Mention it if the kitchen gets busier
- Do not refit a filter that is bent
- Keep the canopy clear for exchange visits
- Book full TR19 cleans alongside filter changes
Fresh filters improve airflow at the canopy from the moment they’re fitted. Always run the extract during cooking so they catch grease as intended.
Filter exchange and TR19 cleaning work best together. Setting both up on a schedule means neither slips.
Childwick Green kitchens: local notes
There are about 4 restaurants, cafés and canteens and about 4 sandwich bars and takeaways in and around Childwick Green, up to about a mile and a half out, according to the Food Standards Agency’s register. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Fire safety in Childwick Green falls to 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 St Albans City council inspect food businesses in Childwick Green. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Volunteers running a hall kitchen near Church of St Mary, or anywhere in Childwick Green, may not know when the extract was last cleaned, and a grease test settles it. Historic houses near Childwick Green, such as Childwickbury Manor about 0.4 miles south-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Your questions about grease filter exchange in Childwick Green
Which fire and rescue service is responsible for Childwick Green?
That is Hertfordshire 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.
Can a school canteen extract in Childwick Green be done out of term time?
Yes, out-of-term visits are normal for schools. With about 4 schools and colleges on the FSA’s register within roughly a mile and a half of Childwick Green, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
What about areas you cannot get to?
Anything we cannot reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
How much does a filter exchange service cost?
Filters, canopies and how often you need visits all affect the price. Send us details or pictures and we will quote, normally within one working day.
Is there a cleaning option for the filters we have?
Yes. 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.
Do you work in Childwick Green?
Yes. Our area takes in London and the counties of South East England, and that includes Childwick Green.
What paperwork should we keep on file?
Each report and certificate we give you, filed in the maintenance log with your in-house cleaning records. BESA advises that certificates record the date, location and technician.
How we price grease filter exchange
You’ll get a fixed price before we start. It takes into account:
- How easy every part is to reach
- A single visit or a regular plan
- The scale of the work
- The number of sites or systems
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Any access panels or hatches you can see
- Where the site is and what kind of site it is
- Your opening hours and when the area is out of use
- Your last certificate, test record or report
Getting a quote does not take long. Send a few details and photos, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Multi-site and managed buildings
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
The process
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes anything from a few minutes to an hour or so, depending on the number of filters, and the area is cleaned down before we leave. If you can send photos, we can arrive in Childwick Green knowing what to expect.
- The filters in each canopy are measured and counted.
- An exchange schedule is agreed to suit your cooking.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- We take the greasy set away and confirm the next date.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Agree a time when the area can be out of use

We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then send you a fixed quote. To start, call 0345 646 2711, or send details by email.
