TR19 inspections and grease testing in Coldblow, Greater London
TR19 inspections and grease testing for businesses, landlords and public buildings in Coldblow. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Kitchens taken over with no cleaning records
- Systems that need surveying before cleaning
- Uncertainty over how often to clean
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, and that takes a morning or less for one kitchen, more where there are several systems. Loading bays, visitor permits and roof access are the first things we ask about for a site in Coldblow.
- First we book a time that will not disrupt cooking.
- The system is checked from canopy to discharge.
- We take WFTT or DTT readings at set points along the system.
- Each test point and any access problems are photographed.
- We send a report setting out the readings, pictures and next steps.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Name a contact who can let us in at the agreed time
- Mention any sign-in, permit or induction we need

Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before any work starts.

TR19 inspection in Coldblow
After a clean, post-clean verification checks the result, with new readings and pictures of the cleaned areas. It shows whether the system was left in the condition the paperwork describes. If you’re dealing with post-clean verification after another contractor’s clean and parts of the system left out of past cleans, we can put it right.
Kitchens in Coldblow, 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, so a regular TR19® clean protects everyone in it.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Part by part
Restaurants, pubs and hotels
We test between services, early in the morning or after close so trading is not affected.
Canopy and plenum
We look over the canopy, inside and out, and note where grease has gathered.
Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Never cook with filters missing
- Flag oily drips near the extract
- Keep TR19 certificates, readings and reports together
- Tell us if menus or opening hours change
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can arrange it.
Keep all TR19 records together so the history is easy to show.
Why it’s worth doing now in Coldblow
An EHO visit, an insurance renewal or a fire risk assessment is a bad time to find your extract records are thin. A recent inspection report means you are ready when asked. A busy site in Coldblow builds up dirt and wear quickly, so putting it off makes the eventual job larger.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and the price is agreed before any work starts.

Kitchen extracts in Coldblow
Food Standards Agency records list about 59 restaurants, cafés and works canteens and about 31 takeaways and sandwich shops in and around Coldblow, up to about a mile and a half out. Each kitchen extract among them can be measured for grease to set the right cleaning interval. Food hygiene inspections in Coldblow are the job of Bexley council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Most London extract cleaning happens at night, after the last service.
School kitchens, at schools like Maypole Primary School for example, are usually cleaned in the holidays so no lunches are lost. Where a hall near Church of St Mary the Virgin, or anywhere in Coldblow, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Coldblow questions
What do you need to know about parking in Coldblow?
A loading bay, a visitor permit or off-street space near the site in Coldblow makes the visit easier to plan. If the building has a loading slot system, we will book into it.
Do you clean school canteen extracts around Coldblow out of term?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 17 schools and colleges with food registrations within roughly a mile and a half of Coldblow. Send us your term dates when you give us a ring on 0345 646 2711 or drop us a line, and we’ll fit the work in.
Is there a survey before the work?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
What is grease thickness testing?
Grease thickness testing measures the layer of grease on the duct surfaces, by WFTT or DTT. The results are given in microns.
What is post-clean verification?
Post-clean verification is a check after a clean, with fresh grease readings and pictures. It works whoever carried out the clean.
Do you carry out TR19 audits for insurers?
Yes, for kitchens across the South East and London. Share the insurer’s request so the report addresses it.
How often should a kitchen extract be inspected?
It depends on how heavily the kitchen cooks. BESA sets minimum cleaning intervals of 3, 6 or 12 months by daily use, and grease readings help set the real interval.
What happens on a pre-clean survey?
A survey finds out how the system is laid out, how dirty it is and what can be reached, before anyone starts cleaning. Any access problems are flagged ahead of the clean.
What we’re called out for in Coldblow
When a site in Coldblow changes owner or cleaning contractor, the records do not always follow. Without them, nobody knows how much grease is in the system or when it was last cleaned.
The symptoms we are asked about most are:
- Sites with gaps in their extract records
- Insurance renewals needing proof of TR19 cleaning
- Surveys needed before quoting a full clean
- Heavy grease suspected in the plenum or ducts
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Bexley Hospital is the nearest hospital to Coldblow, about 1.9 miles north-west.
Questions to ask before booking
- What happens if part of the system cannot be accessed
- Whether the work can be done while the site is closed
- If they look at the system before pricing
- Whether a written report and photos are included

What else we do in Coldblow
What affects the cost of TR19 inspection
We quote each job individually. These are the things that affect it:
- Travel, parking and unloading
- How many systems or sites are involved
- Whether we need access equipment or extra panels
- When the work can happen, such as evenings, overnight or weekends
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 will explain each part.
Asking for a quote
When you contact us, these details help:
- Detail shots of panels, filters and grilles
- 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
- Any symptoms, from odd noises to smells or leaks
To get a fixed quote, give us a ring on 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We typically come back within one working day.
What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
