How we handle TR19 inspection in Westerham
BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Grease testing shows whether your kitchen needs cleaning more often than that. We’re often asked to deal with cleaning intervals that may not suit the kitchen and kitchen extract systems with no recent grease readings, on wet film thickness tests, access surveys and pre-clean surveys.
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 Westerham, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Honest limits
In fairness, some problems need a different fix:
- Fan breakdowns, which need a repair visit
- Removing the grease, which is a separate clean
- Fire safety duties beyond the extract system

Multi-site and managed buildings
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.
We also work for facilities teams across offices, schools and healthcare in Westerham and across Greater London. Work can be phased by floor, building or site around the people who use them.
How we price TR19 inspection
Before we fix a price, we need to know a few things. We look at:
- Whether it’s a one-off visit or part of a schedule
- When the work can happen, such as evenings, overnight or weekends
- Whether we need access equipment or extra panels
- How many systems or sites are involved
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.
What we need to know
To help us quote quickly, please include:
- The site address and the type of premises
- The paperwork from the last visit, if you have it
- Wide photos of the system and the area around it
- Problems your staff have spotted
For a fixed quote, call 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You’ll normally have a quote within one working day.
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Keep access panels clear and unpainted
- Keep TR19 certificates, readings and reports together
- Clean grease off the canopy between professional cleans
- Look out for grease drips round the canopy edge
Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can arrange it.
Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.
How the visit works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes a morning or less for one kitchen, more where there are several systems. Security desks and permits-to-work are routine in London, so let us know what your building in Westerham needs from us.
- The visit is arranged for when the kitchen isn’t busy.
- Every part of the system is examined, end to end.
- Grease readings are taken at set points using WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- The findings go into a report with readings, photos and a recommended next clean.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Allow time for equipment near the work to be turned off and cool down

There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, ring 0345 646 2711 or email us.

How the job changes from site to site
Horizontal duct runs
If a run has no access panel, we note it so it can be fixed before the clean.
Extract fan and discharge
The discharge at the end of the system is checked as well, as grease can build up there too.
Westerham: your questions answered
Can you work in Westerham outside opening hours?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Your opening times are the first thing we ask for.
Does London parking affect a job in Westerham?
London parking can be tight, so details of loading bays and permits help. Much of our London work is done overnight, which helps.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Do you look at the system first?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
Is TR19 a legal requirement?
No, not in itself. But the responsible person must assess and reduce fire risk under the Fire Safety Order 2005, and grease in the extract is part of that. Many insurers also expect TR19 cleaning.
What do the grease readings need to be?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. 500 microns or more at any point calls for immediate spot cleaning.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
TR19 inspection in Westerham: the local picture
The FSA’s food hygiene register includes about 7 pubs and bars in Westerham and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected. Kitchens in Westerham get their food hygiene inspections from Sevenoaks council. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.
If you run catering at a historic house or estate in the area (Quebec House is about 0.2 miles south-east), event kitchens in older buildings often have awkward duct runs that need planning. 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.

Common problems we fix in Westerham
When a site in Westerham changes owner or cleaning contractor, the records don’t always follow. With no history, the current state of the extract is a guess.
Look out for any of the following:
- Post-clean verification after another contractor’s clean
- Insurers asking for TR19 evidence
- Kitchen extract systems with no recent grease readings
- Missing access panels found on survey
A hospital like Tandridge Priory, about 2.2 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
