How we handle TR19 inspection in Aperfield
Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. Our TR19 audits give sites in Aperfield and across Greater London a clear record of the system’s condition. If you have kitchen extract systems with no recent grease readings and extracts that may be over the 200 micron mean, we can put it right, from insurer audits, access surveys and pre-clean surveys onwards.
In London, few kitchens can spare a day to close, so extract cleaning in Aperfield is typically done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Grease, kitchens and Aperfield
Food Standards Agency data counts about 11 restaurants, cafés and canteens and about 10 takeaways and sandwich shops within roughly a mile and a half of the centre of Aperfield. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. In Aperfield, food businesses are inspected by environmental health officers from Bromley council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier.
A hall kitchen that only cooks for events, whether near St Mark's Church or elsewhere in Aperfield, still needs its extract cleaned, just less often. For schools such as Biggin Hill Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

What happens on the day
The visit has three parts: set-up, the treatment itself and the sign-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, and that takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Most London sites cannot stop for the day, so work in Aperfield is typically done overnight, early in the morning or at weekends.
- We go through any past certificates and reports.
- The layout is traced from the canopy to the discharge.
- We note where access panels are and where more are needed.
- We measure the grease and photograph each point.
- We report back with readings and a fixed quote.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Mention any parking or loading restrictions
- Move anything stored near the system

Part by part
Canopy and plenum
We look over the canopy, inside and out, with readings where grease collects.
Extract fan and discharge
The extract fan and its housing collect grease too. They’re included in the readings and photos.
Common problems we fix in Aperfield
Insurers, fire officers and environmental health officers look to TR19® as the benchmark. It isn’t legislation; the legal duty comes from the Fire Safety Order 2005, under which the responsible person must reduce fire risk, and grease in the extract is part of that risk.
Signs it’s time to call us include:
- Sites with gaps in their extract records
- Extracts that have never been grease tested
- Insurers asking for TR19 evidence
- Post-clean verification after another contractor’s clean
If you run catering at a historic house or estate in the area (Down House is about 1.7 miles north), event kitchens in older buildings often have awkward duct runs that need planning.
What your quote should include
- Proof of accreditation you can verify
- Whether the price is fixed
- Whether the whole system is included, or only the parts that are easy to reach
- Whether inaccessible sections are listed on the report
What affects the quote in Aperfield
The price is fixed before any work begins. It’s based on:
- Travel, parking and unloading
- One-off work versus a regular cycle
- Access, including roofs, risers and ceiling voids
- Any permits to work or inductions
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.
Helping us quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Any symptoms, from odd noises to smells or leaks
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
- How we’d reach plant on a roof or in a plant room
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Fan breakdowns, which need a repair visit
- Ductwork that was designed or installed badly
- Sections with no access, until panels are fitted
If you’re not sure, just phone us on 0345 646 2711 or email us and we’ll give you a straight answer before you book.
What we work on in Aperfield
- Pre-clean surveys
- Deposit thickness tests
- Wet film thickness tests
- Access surveys
- Insurer audits
- Post-clean checks
What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Looking after it afterwards
Results last longer with the right care. We suggest:
- Never cook with filters missing
- Look out for grease drips round the canopy edge
- Have the latest report ready for insurance renewals
- File every inspection report with your certificates
Any access problems we found are listed with a suggested fix. Fitting them before the next clean means the whole system gets done.
Keep filters clean and in place. Missing or damaged filters let grease straight into the plenum.
Your questions about TR19 inspection in Aperfield
Can you work in Aperfield outside opening hours?
Yes, evening, overnight and weekend work is normal for us. That way a site in Aperfield does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Can you clean school kitchen extracts in Aperfield during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Aperfield, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
What is post-clean verification?
It’s an inspection after cleaning, to show what state the system was left in, whoever did the clean.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.
How long does a TR19 inspection take?
Expect it to take anything from an hour for a small canopy and short duct to a good part of a day for a large site. The visit is timed so cooking isn’t disrupted.
How much does TR19 inspection cost in Aperfield?
It depends on the site, so we quote each one individually. To get one, ring 0345 646 2711 or use the quote form and tell us about the site and its opening hours.
What do you do to protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Can you price the work without visiting?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
