- Grease collecting in the filter channels
- Hand-washed filters that still look greasy
- Damaged filters letting grease past
Honest limits
To be straight with you, some problems need a different fix:
- An extract that was undersized from the start
- Grease behind the filters that a swap cannot remove
- Grease already built up in the ductwork, which needs a full TR19 clean

About our grease filter exchange in Aspenden
Cleaning filters by hand takes staff time and is easy to put off. With a filter exchange, we bring a clean set and take the dirty one away and the canopy is refilled right away. Common call-outs are for bent or damaged filters that don’t sit properly and staff short of time to wash filters, across mesh filters, baffle filters and island canopies.
For a kitchen in or near Aspenden, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Grease, kitchens and Aspenden
The FSA’s food hygiene register includes about 6 pubs, bars and clubs in and around Aspenden, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. The fire and rescue service for Aspenden is Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Aspenden, food businesses are inspected by environmental health officers from East Hertfordshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand.
School kitchens, at schools like Millfield First and Nursery School for example, are typically cleaned in the holidays so no lunches are lost.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Part by part
Busy restaurant and pub kitchens
The more a kitchen cooks, the more grease the filters see. Regular changes help protect the ductwork.
The plenum
A greasy plenum is a sign filters have been left too long or that the next TR19 clean is due.

How it works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes a short visit, depending on how many filters the canopies hold. We agree a date with you, plan the drive to Aspenden and turn up when the site is quiet.
- The filters in each canopy are measured and counted.
- An exchange schedule is agreed to suit your cooking.
- On each visit, we remove the greasy filters.
- Clean filters go in and we check they sit snugly.
- The dirty filters leave with us and the next visit is booked.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us the best time to work, such as after service or at a weekend

Leave it or put it right?
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 one of the easiest to let slip. Systems in rural buildings are often out of sight and out of mind.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.
Why book with us

Questions from Aspenden
Do you work at weekends in Aspenden?
Yes, out-of-hours work is a big part of what we do. The work in Aspenden can fit around your hours. Let us know the hours you are closed and we will book within them.
Who inspects food businesses in Aspenden?
The local authority for Aspenden is East Hertfordshire council, and its environmental health team does the inspecting. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can you clean our existing filters instead?
Yes, filters can be cleaned on a schedule as well as exchanged. We’ll explain the options when you get in touch.
How much does a filter exchange service cost?
Filters, canopies and how often you need visits all affect the price. Tell us what you have and we will come back with a fixed quote, normally within one working day.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Which records should we keep?
Everything that shows the system is looked after: reports, certificates, pictures and your own cleaning or check logs. One maintenance log per site keeps it simple.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
Does a filter exchange replace TR19 cleaning?
It isn’t. The rest of the system still collects grease at an interval set by risk assessment.
For landlords and multi-site operators
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Do you need grease filter exchange in Aspenden?
Long cooking hours in Aspenden or anywhere else mean more grease on the filters. Heavy daily use means fast build-up, so it needs more frequent changes.
It’s time to book a visit if you see:
- Filters that come out of the sink still dirty
- Smoke and heat lingering under the hood
- Filters so greasy the air can barely pass
- Staff short of time to wash filters
If you run a church or community hall kitchen, near Parish Church of St Mary or elsewhere in Aspenden, its extract still collects grease from every lunch and event.
