How we handle TR19 inspection in Preston
A pre-clean survey looks at the whole system, from canopy to discharge. Access is checked along the full length, and record grease readings at set points. We’re often asked to deal with heavy grease suspected in the plenum or ducts and insurance renewals needing proof of TR19 cleaning, across access surveys, post-clean checks and wet film thickness tests.
Kitchens in Preston, 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.
Good records are part of the job. You get a written report with pictures after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Horizontal duct runs
Grease can gather thickly at bends and along long runs, out of sight of the kitchen.
Restaurants, pubs and hotels
Inspections are done when the kitchen is closed or quiet so trading is not affected.
Common questions in Preston
Who is the fire and rescue service for Preston?
It’s London Fire Brigade, which covers Preston. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you work at weekends in Preston?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Do you work in Preston?
Yes. Preston is part of the area we cover, as part of our area across London and the South East.
How do you measure grease in a kitchen extract?
WFTT and DTT are the two methods for measuring grease thickness, in microns. We take readings at set points from canopy to fan.
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.
Do you check other contractors’ cleans?
It’s an inspection after cleaning, to show what state the system was left in, for our cleans and other firms’ alike.
Can you quote from photos?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
Staff cleaning versus specialist work
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, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
When to call us in Preston
Not every section of a kitchen extract is easy to get to, and grease can be missed there clean after clean. An inspection of a system in Preston shows where access panels are missing, so the gaps can be closed.
The symptoms we’re asked about most are:
- Systems that need surveying before cleaning
- Kitchen extract systems with no recent grease readings
- Ductwork where grease may be over the TR19 limits
- Post-clean verification after another contractor’s clean
Church and community hall kitchens, near Church of the Ascension or anywhere around Preston, are easy to forget, but their extracts collect grease like any other.
Before booking anyone
- Whether a survey comes first
- What insurance they carry
- Whether inaccessible sections are listed on the report
- Which accreditations they hold, and whether you can check them
Multi-site and managed buildings
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
The process
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before we start, and the area around the work is covered and protected. On site, it takes a couple of hours for a typical kitchen extract system. Expect the work in Preston to happen after your last customer leaves, not during trading.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Make sure someone can let us in and lock up afterwards
- Let us know about parking and loading

Kitchen extracts in Preston
According to Food Standards Agency records, there are about 27 pubs and bars and about 6 hotels and B&Bs in Preston and the streets around it, up to about 1.5 miles out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Most London extract cleaning happens at night, after the last service. Preston is covered by London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
A kitchen near South Kenton station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. School kitchens, at schools like Preston Park Primary School for example, are usually cleaned in the holidays so no lunches are lost.

Why it’s worth doing now in Preston
A pre-clean survey avoids surprises on the night. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, so the clean covers the whole system. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before work begins.
Why us?
- Fully insured
- Ventilation hygiene specialists since 2009
- One number for every site across the South East and London
- We diagnose before we treat
What affects the cost of TR19 inspection
The survey tells us what the work involves. The main factors are:
- The number of sites or systems
- Whether we need access equipment or extra panels
- The condition of the system
- Parking and loading at the site
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, ring 0345 646 2711 or use the quote form for straight advice and a fixed quote.
What we need to know
We can often survey from pictures. The most useful are:
- The site address and the type of premises
- When the site is open and when it’s quiet
- Any access panels or hatches you can see
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before we start.
