Greater London · Kitchen extract cleaning
Kitchen extract cleaning in Westerham, Greater London
Kitchen extract cleaning in Westerham from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- A smoky, hot kitchen with weak extraction
- Extraction mentioned at an environmental health visit
- Grease smells coming from the extract
Multi-site and managed buildings
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
About our kitchen extract cleaning in Westerham
Across Westerham, we clean kitchen extract systems to BESA TR19® Grease. We survey first and take grease readings, then clean the canopy, plenum, filters, ducts, fan and discharge. At the finish there’s a TR19 certificate and a before and after photo report. Typical jobs include heavy grease build-up inside the duct runs and grease smells coming from the extract, on vertical risers, extract fans and horizontal duct runs. Need a TR19 duct cleaning contractor for Westerham? We’ve been cleaning kitchen extracts across the South East since 2009, with a certificate and photo report after every clean.
Access decides how thorough a clean can be. Where a duct run has no panels, we say so on the report and can fit new ones.
Kitchens in Westerham, like many across London, can share a building with flats or offices, with the duct running up through shared risers. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.
A written report with pictures follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What we’re called out for in Westerham
We often find duct sections that haven’t been cleaned since they were installed. Most of the time it’s because there were never enough access panels, so nobody could get to them. Grease in those sections keeps building out of sight.
Common reasons sites call us are:
- Grease dripping from the canopy or filters
- An extract that no longer clears the smoke
- An overdue clean flagged by an EHO or fire officer
- Ductwork thick with old, hardened grease
Quebec House, about 0.2 miles south-east, is one of the historic houses near Westerham; if you run event catering at a venue like that, cleans can be booked between functions.
Questions to ask before booking
- What paperwork you get at the end
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the price is fixed
- Whether they recommend a next date
Westerham: your questions answered
Who inspects food businesses in Westerham?
The local authority for Westerham is Sevenoaks council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can parking be tricky for a job in Westerham?
A loading bay, a visitor permit or off-street space near the site in Westerham makes the visit easier to plan. Working overnight, as we often do in London, normally makes it simpler.
Will my insurer ask for a TR19 certificate?
Many policies require TR19 cleaning, and insurers often ask to see the certificate. An insurer may refuse or reduce a claim if there’s no evidence, so it’s worth checking your policy wording.
Do you work in Westerham?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Westerham.
When do you clean the extract?
The clean is done when the kitchen is not cooking, working evenings, overnight or at weekends to suit you. Equipment needs to be off and cool before any work starts.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
Do you clean the whole extract system or just the canopy?
All of it, from the canopy through to the discharge. Sections with no access are listed on the report, and extra panels can be fitted.
What’s the right cleaning interval for a kitchen extract?
BESA guidance sets minimums by daily cooking hours: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Grease readings can show a shorter interval is needed.
What affects the cost of kitchen extract cleaning
You’ll get a fixed price before work begins. It’s based on:
- A single visit or a regular plan
- The times the site is available
- The size of the system
- How easy every part is to reach
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What we need to know
We can often survey from photos. Try to include:
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
- A few general shots of the system
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Then call us on 0345 646 2711 or use the quote form.
Why deal with it now?
Putting it off simply moves the grease further down the duct. Fat that was soft and easy to remove hardens with heat and time, which is slower to clean. Regular cleans keep each visit shorter. A building in Westerham may have flats or offices above and alongside, and a fault in the system can affect them too.
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

How it works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, and that takes a single shift for most kitchens, with long duct runs and tall risers needing more time. Security desks and permits-to-work are routine in London, so let us know what your building in Westerham needs from us.
- We survey the system, from your pictures or on site, canopy to discharge.
- We take grease readings at set points and give you a fixed quote.
- On the night, the equipment is off and cool and the kitchen is sheeted.
- We work through the system from the canopy to the fan and discharge.
- We re-test, photograph and send your certificate and photo report.
Preparing for the visit
- Mention any parking or loading restrictions
- Mention any sign-in, permit or induction we need
- Find the previous report, if there is one
How to get a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

What kitchen extract cleaning looks like in Westerham
Food Standards Agency data counts about 19 restaurants, cafés and works canteens and about 10 takeaways and sandwich shops in and around Westerham, up to about a mile and a half out. Wherever food is cooked under a canopy, the extract above it gathers grease and needs cleaning on a schedule. Overnight is the normal time to clean a London kitchen extract, so trading is not affected. Westerham is covered by London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Westerham is Tandridge Priory, about 2.2 miles south-west. Where a hall near Church of St Mary the Virgin, or anywhere in Westerham, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Westerham is about 5 miles west of Sevenoaks, in Greater London. From the centre of Westerham to the outskirts, we cover kitchen extract cleaning for every kind of premises, from a single unit to a large public building.

Local streets include Market Square, London Road and High Street, and we cover them all for kitchen extract cleaning. Westerham is on the A25 and B2024, which makes it straightforward for our technicians to reach for kitchen extract cleaning.

Near you in Westerham
Locally, jobs take us to businesses close to The Olde House At Home Public House and the streets around them. For rail, the closest station is Hurst Green station, about 3.4 miles south-west of the centre. A little further out are Tandridge Priory (2.2 miles south-west). Not far away are Betsom's Hill and Dryhill Nature Reserve.
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
Honest limits
It’s worth knowing the limits before booking:
- Damaged duct sections that need replacing
- Fire dampers that will not close (that needs damper testing and remedials)
- Extraction that can’t cope with the cooking because of its design
If you are not sure, just call 0345 646 2711 or send us an email and we will give you a straight answer before booking.
