Kitchen extracts in Rowley Green
Food Standards Agency data counts about 29 restaurants, cafés and works canteens and about 15 takeaways within roughly a mile and a half of the centre of Rowley Green. Swapping filters on a schedule keeps kitchens like these drawing air properly. Kitchens in Rowley Green get their food hygiene inspections from Barnet council. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after. Rowley Green sits within the area of London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Bursars and site managers at schools such as Saffron Green Primary School tend to book extract cleaning for when the kitchen is empty. If you run catering at a healthcare site, such as a hospital like Barnet General Hospital about 1.4 miles east, the extract may need cleaning more often than a part-time kitchen. If your kitchen is in a listed or historic building, like the houses around Rowley Green (Wyllyotts Manor is about 3.7 miles north-east), fitting access panels needs care.

About our grease filter exchange in Rowley Green
A clean set of filters is a simple, regular dose of prevention. It keeps airflow up and grease down between full cleans, and it saves your staff a greasy job. The full TR19 clean then gives the system its clean bill of health. The work covers mesh filters, island canopies and restaurants and pubs, and the jobs we see most are weak extraction at the canopy and grease dripping from the canopy.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In Rowley Green, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Rowley Green: your questions answered
Who is the fire and rescue service for Rowley Green?
Rowley Green is in the area of London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Do you clean school canteen extracts around Rowley Green out of term?
Yes, and it’s the easiest time to do it. Around Rowley Green, the Food Standards Agency lists about 13 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
Do we need to close the kitchen while filters are changed?
Visits are short, and we can come before or after service. There’s no wait between removing and refitting.
How regularly do grease filters need exchanging?
It varies with the type and amount of cooking. If filters clog early, the interval needs shortening and we’ll adjust it.
Do you handle baffle and mesh filters?
We exchange baffle and mesh filters. We record the sizes and number of filters at the start so every set we bring fits.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
Which records should we keep?
Every certificate and report from each visit, filed in the maintenance log, along with your own cleaning log. BESA advises that certificates record the date, location and technician.
The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a few minutes per canopy, longer for a large kitchen with several canopies. Getting kit into a London building takes planning, so let us know where we can load and park in Rowley Green.
- First, we record the size, type and number of filters in each canopy.
- A change schedule is agreed to match the kitchen’s cooking hours.
- At each visit, the greasy filters are lifted out.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Getting ready for the visit
- Find the previous report, if there is one
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about permits to work or site inductions
Ask for a quote
To help us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711 or use the quote form.

Keeping the system healthy
After the visit, a few habits help the work last:
- Never cook with the extract switched off
- Report a dripping canopy early
- Make sure no filter is left out
- Clear anything stored on or near the canopy
Your team carries on as normal, without the filter washing. Just keep the canopy clear for the next visit and tell us if service times change.
Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.
Honest limits
We won’t sell you work that doesn’t address the problem, so here are the limits:
- A canopy too small for the cooking beneath it
- Greasy ducts and risers that a filter change won’t reach
- A canopy that needs a proper clean
If in doubt, call 0345 646 2711 or send us an email and we’ll say what we think before you book.

For landlords and multi-site operators
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Why act early in Rowley Green
Clogged filters choke the extract. The kitchen gets hotter and smokier while the fan strains. A regular exchange keeps the airflow where it should be. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.

What affects the quote in Rowley Green
The survey tells us what the work involves. The main factors are:
- Whether it’s a one-off visit or part of a schedule
- What state the system is in
- Parking and loading at the site
- Site requirements such as sign-in and permits
The cost 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 any work starts, so you know where you stand.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
- Any previous report or certificate
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Different parts, different methods
Baffle filters
Baffle filters are robust and widely used in commercial canopies. They do not clean themselves as the collected grease builds up between the blades.
Canopy filter housings
The filter housing holds each filter at an angle in the canopy. A damaged housing leaves gaps.
