Grease filter exchange in Cooper's Green, done properly
We run grease filter exchange for all kinds of kitchens in Cooper's Green, whether there’s one canopy or many. We can come before or after service, so cooking is not interrupted. Typical jobs include a canopy running with filters missing and filters so greasy the air can barely pass, on wall canopies, restaurants and pubs and school and hospital kitchens.
In a small place like Cooper's Green, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
The sign-off is always in writing: 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.

Kitchen extracts in Cooper's Green
According to Food Standards Agency records, there are about 5 bars, pubs and nightclubs within roughly a mile and a half of the centre of Cooper's Green. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Cooper's Green is covered by 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. Environmental health officers from Welwyn Hatfield council inspect food businesses in Cooper's Green. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
For schools such as Howe Dell Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Cooper's Green is Hill End Hospital, about 2.2 miles south-west. If your kitchen is in a listed or historic building, like the houses around Cooper's Green (Hatfield House is about 2.7 miles east), fitting access panels needs care.

Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Leave it or put it right?
Clogged filters choke the extract. The kitchen gets hotter and smokier while the fan strains. Keeping filters clean keeps the extract working properly. Somewhere as small as Cooper's Green, losing a kitchen or building to a fault is felt by everyone who uses it.
What you pay depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before we start, so there are no surprises.

Looking after it afterwards
So the system stays in good health:
- Keep filter exchange and TR19 cleaning on the same plan
- Report damaged filters so they can be replaced
- Clear anything stored on or near the canopy
- Never cook with the extract switched off
Nothing changes for your staff, except one less greasy job. Make sure we can reach the canopy on exchange day and let us know of any changes to opening hours.
Filters that are left too long stop protecting the system. A regular cycle keeps the rest of the system cleaner between full cleans.
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.

The process
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a short visit, depending on how many filters the canopies hold. Somewhere like Cooper's Green, lanes, gates and parking are worth mentioning in advance.
- 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.
Getting ready for the visit
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids
- Let us know about parking and loading
Ask for a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
