Grease filter exchange for kitchens and businesses in Patchetts Green
Washing filters in the kitchen sink is messy and easily missed on a busy week. An exchange service means clean filters arrive and greasy ones leave and the canopy is refilled straight away. The work covers wall canopies, restaurants and pubs and baffle filters, and common reasons people get in touch are poor airflow through the filters and a greasy plenum behind the filters.
Work in a small place like Patchetts Green starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
A written report with pictures follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Common problems we fix in Patchetts Green
Filters get bent and damaged with handling. Damaged filters do not sit flush and grease passes round them.
Any of these means the system needs a check-up:
- Filters left unwashed on busy weeks
- Filters that leave gaps in the canopy
- Hand-washed filters that still look greasy
- Grease collecting in the filter channels
For schools such as Queens' School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.
What your quote should include
- If they look at the system before pricing
- When they can work, and whether that is outside your opening hours
- Whether they’re fully insured
- Whether a written report and photos are included
Part by part
The plenum
With good filters, less grease ends up in the plenum, but it still needs cleaning as part of TR19.
Canopy filter housings
We check that filters sit snugly in the housing at each visit, because gaps let grease through.
When something else is needed
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- An extract that was undersized from the start
- Grease already built up in the ductwork, which needs a full TR19 clean
- Odours from the discharge that filters won’t stop
If in doubt, ring 0345 646 2711, or send details by email and we’ll say what we think.
What the work covers
- Restaurants and pubs
- Island canopies
- Baffle filters
- School and hospital kitchens

What affects the quote in Patchetts Green
The diagnosis comes before the price. The main factors are:
- What state the system is in
- Site requirements such as sign-in and permits
- A single visit or a regular plan
- How big the system is
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, call us on 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.
Helping us quote
When you call or email, it’s useful to have:
- Where the site is and what kind of site it is
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- Your opening hours and when the area is out of use
To get a fixed quote, ring 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
What we do, step by step
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, which takes a short visit, depending on how many filters the canopies hold. We agree a date with you, plan the drive to Patchetts Green and turn up when the site is quiet.
- We start by noting how many filters you have and what type they are.
- We agree a schedule that suits how much the kitchen cooks.
- On each visit, the dirty filters come out of the canopy.
- Clean filters go straight back in, seated properly with no gaps.
- If a filter is damaged or the plenum needs attention, we tell you.
Preparing for the visit
- Tell us where we can park and unload
- Mention any locked doors, roof access or ceiling voids
- Agree a time when the area can be out of use
Getting a quote
To help us quote: where the site is, what it is and its opening hours, a few pictures and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711, or send details by email.

Can you get to a site in Patchetts Green?
Yes, Patchetts Green is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Can you work in Patchetts Green outside opening hours?

Normally not. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages so parts stay in use.

What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Do I get a report after the visit?
Yes. It’s your proof that the work was done: a written, dated record with photos of what we did and anything we couldn’t access.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
Where do the greasy filters go?
We take them away to be cleaned, so your staff don’t have to wash them. Clean filters go straight in.
Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
What grease filter exchange looks like in Patchetts Green
There are about 26 cafés, restaurants and staff canteens and about 9 takeaways across Patchetts Green and its immediate surroundings (about a mile and a half), 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. The fire and rescue service for Patchetts Green is Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. In Patchetts Green, food businesses are inspected by environmental health officers from Hertsmere council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
