Rayners Lane TR19 inspection
TR19 inspection for Rayners Lane and the surrounding area: diagnosis first, then a fixed quote, the work and a report with pictures. Ask us for a fixed quote.
- An insurer’s request for a TR19 audit
- Missing access panels found on survey
- Post-clean verification after another contractor’s clean
Common problems we fix in Rayners Lane
Grease is fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Measuring it is the first step to keeping it under control.
It’s time to book a visit if you see:
- Sections of duct that cannot be reached
- Heavy grease suspected in the plenum or ducts
- Uncertainty over how often to clean
- Extracts that have never been grease tested
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Rayners Lane is Clementine Churchill Hospital, about 1.9 miles east.
What to look for in a quote
- What hours they’ll be on site
- If the quote is a fixed price or an estimate
- How areas they can’t reach will be recorded
- Proof of accreditation you can verify
How we handle TR19 inspection in Rayners Lane
Think of a TR19 inspection as the diagnosis before the treatment. Readings, photos and notes on access are gathered from end to end, so the quote and the clean fit the real system. Typical jobs include pre-clean surveys before a first TR19 clean and insurance renewals needing proof of TR19 cleaning, on post-clean checks, deposit thickness tests and access 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. For a kitchen in Rayners Lane, that usually means a longer system to clean and more access panels to plan around.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Managing agents and facilities teams in Rayners Lane
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Honest limits
A few issues sit outside what this work can do:
- Hidden runs that need access panels first
- Removing the grease, which is a separate clean
- Fan breakdowns, which need a repair visit
Not sure which it is? You can ring 0345 646 2711, or email photos and we will tell you honestly.
Parts of the system we cover
- Access surveys
- Post-clean checks
- Insurer audits
- Deposit thickness tests
- Pre-clean surveys
- Wet film thickness tests
Leave it or put it right?
Skipping grease testing leaves the cleaning interval to guesswork. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, and you can only act on that if you’ve measured it. Planning ahead in Rayners Lane lets you pick a quiet night rather than lose a busy one.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.

Different parts, different methods
Schools, hospitals and care homes
Hospital and care home kitchens can cook all day, every day. Testing shows if the cleaning interval keeps pace.
Canopy and plenum
Clean-looking filters don’t mean a clean plenum. That is why we test behind them.
How the visit works
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes a couple of hours for a typical kitchen extract system, and the area is cleaned down before we leave. Before any visit in Rayners Lane, we agree where the van can stop and how equipment reaches the system.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
How to prepare
- Agree a time when the area can be out of use
- Let us know about permits to work or site inductions
- Dig out any earlier paperwork for the system
Getting a quote
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.
Advice
Rayners Lane questions
Which fire authority looks after Rayners Lane?
That is 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.
Can you come to Rayners Lane after we close?
Yes, evening, overnight and weekend work is normal for us. That way a site in Rayners Lane doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
What grease levels does TR19 allow?
TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, with 500 microns or more anywhere needing immediate spot cleaning.
What does TR19 inspection cost?
It depends on the site, so we quote each one individually. For a quote, call us on 0345 646 2711, or send details by email and tell us about the site and its opening hours.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Can you inspect our extract for our insurance company?
Yes. Many insurers ask for proof of TR19 cleaning and inspection, and our audit gives a clear record of the system’s condition, with recommendations where something needs doing.
What do you need from me for a quote?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then give us a ring on 0345 646 2711 or drop us a line.
Grease, kitchens and Rayners Lane
According to Food Standards Agency records, there are about 24 bars, pubs and nightclubs and about 4 hotels, B&Bs and guest houses across Rayners Lane and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Rayners Lane sits within the area of 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. In London, kitchens are normally cleaned overnight, when the kitchen is closed and loading is easier.
If you run catering at a historic house or estate in the area (Headstone Manor is about 1.7 miles north-east), event kitchens in older buildings often have awkward duct runs that need planning. Where a hall near St. Andrew’s Church, or anywhere in Rayners Lane, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What else we do in Rayners Lane
What staff can safely do
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. 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 can diagnose it and quote.
