- Grease building up behind the canopy filters
How the job changes from site to site
Mesh filters
Older or smaller canopies often use mesh filters. We exchange them on the same basis as baffles.
Busy restaurant and pub kitchens
Kitchens that fry and grill all day load their filters fast. Their exchange schedule is normally the tightest.
About our grease filter exchange in Langley
Cleaning filters by hand takes staff time and is easy to put off. An exchange service means clean filters arrive and greasy ones leave, so the canopy is never left without filters. If you have smoke and heat lingering under the hood and a canopy running with filters missing, we can put it right.
In a village or hamlet like Langley, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Common questions in Langley
Who carries out food hygiene inspections in Langley?
That’s North Hertfordshire council, whose environmental health officers carry out food hygiene inspections in Langley. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can you work in Langley outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in Langley doesn’t have to lose a day’s trading. Just phone us on 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
Do you work in Langley?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Langley.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we’ll quote them together.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
What affects the quote in Langley
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether we need access equipment or extra panels
- Site requirements such as sign-in and permits
- Whether it’s a one-off visit or part of a schedule
- The number of sites or systems
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, give us a ring on 0345 646 2711 or email us for straight advice and a fixed quote.
Asking for a quote
You don’t need the technical terms. It helps if you can send:
- The paperwork from the last visit, if you have it
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
- Problems your staff have spotted
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before we start.
Aftercare tips
Once we’ve finished, these simple steps help:
- Keep filter exchange and TR19 cleaning on the same plan
- Clean the canopy surfaces regularly
- Tell us if a filter is bent or damaged
- Let us know if your cooking hours increase
We tell you if we spot anything in the canopy that needs attention. It can be a sign that a full TR19® clean is due, and we can arrange it.
Filters that are left too long stop protecting the system. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.
The process
Each visit runs to the same pattern: protect the area, make the system safe, do the work, clear away and hand over the paperwork. On site, the work takes anything from a few minutes to an hour or so, depending on the number of filters. A quick note on how to find the site and where to park makes a visit to Langley run smoothly.
- We look at the canopies and the condition of the filters.
- We note any filters that are bent, damaged or missing.
- Greasy filters are swapped for clean ones.
- The filters are checked for fit before we go.
- We tell you if the plenum or canopy needs a clean.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive
- Make sure someone can let us in and lock up afterwards
Get a fixed quote
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Advice
What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
When it’s something else
Some problems need a different service or another trade:
- A canopy that does not capture the vapour properly
- Cooking smells reaching neighbours, which need odour control
- Grease behind the filters that a swap cannot remove
If in doubt, phone us on 0345 646 2711 or drop us a line and we’ll say what we think before you book.

Grease, kitchens and Langley
The FSA’s food hygiene register includes about 4 pubs and bars within 1.5 miles or so of the middle of Langley. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Langley sits within the area of 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. It’s North Hertfordshire council that sends environmental health officers to food businesses in Langley. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Langley is Lister Hospital, about 2.7 miles north. If you look after a school kitchen, at a school such as The Thomas Alleyne School or anywhere near Langley, the holidays are the usual time for a TR19® clean. If your kitchen is in a listed or historic building, like the houses around Langley (Knebworth House is about 1.3 miles south-east), fitting access panels needs care.

Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
