TR19 inspection in Northwood
A fixed schedule doesn’t always match how a kitchen really cooks. In a busy kitchen, grease can build faster than the minimum intervals allow for, which is why measurement matters. We give your risk assessment measured figures rather than guesses. The work covers pre-clean surveys, insurer audits and post-clean checks, and common reasons people get in touch are an insurer’s request for a TR19 audit and kitchen extract systems with no recent grease readings.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. In Northwood, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
The paperwork matters as much as the work. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What happens if it’s left?
An EHO visit, an insurance renewal or a fire risk assessment is a bad time to find your extract records are thin. An inspection now gives a site in Northwood a current picture. In Northwood, as across London, ductwork often passes through shared risers and other people’s space.
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before any work starts.

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what TR19 inspection will not do:
- Hidden runs that need access panels first
- Mechanical faults in the extract
- Design faults in the extract system
If in doubt, phone us on 0345 646 2711 or send us an email and we will say what we think.
What we work on in Northwood
- Deposit thickness tests
- Post-clean checks
- Wet film thickness tests
- Pre-clean surveys
- Access surveys
- Insurer audits
Common problems we fix in Northwood
Some parts of a system are hard to reach, so those sections can be skipped time and again. An inspection of a system in Northwood shows where access panels are missing, so panels can be fitted.
Keep an eye out for any of the following:
- Missing TR19 certificates or history
- Systems cleaned on a calendar with no measurements
- Insurers asking for TR19 evidence
- Ductwork where grease may be over the TR19 limits
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Headstone Manor is about 3.3 miles south-east), access may need planning.
What your quote should include
- Whether a survey comes first
- What hours they’ll be on site
- What paperwork you get at the end
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
For landlords and multi-site operators
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
TR19 inspection around Northwood
Look up Northwood on the FSA’s food hygiene register and you will find about 51 restaurants, cafés and canteens and about 26 takeaways and sandwich shops within roughly a mile and a half of the centre of Northwood. For any of them with a canopy, measuring grease is better than guessing when to clean. Overnight is the normal time to clean a London kitchen extract, so trading is not affected. Environmental health officers from Hillingdon council inspect food businesses in Northwood. 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.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Northwood and Pinner Cottage Hospital is the nearest hospital to Northwood, about 1 mile south. For schools such as Frithwood Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a couple of hours for a typical kitchen extract system. Getting kit into a London building takes planning, so let us know where we can load and park in Northwood.
- First we book a time that will not disrupt cooking.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease readings are taken at set points using WFTT or DTT.
- Each test point and any access problems are photographed.
- You get a report with readings, photos and recommendations.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any parking or loading restrictions
- Name a contact who can let us in at the agreed time

Advice
Different parts, different methods
Schools, hospitals and care homes
Inspections are planned around mealtimes and holidays to avoid disruption.
Restaurants, pubs and hotels
Kitchens that cook for long hours build up grease faster. Readings show if the cleans are frequent enough.
Northwood questions
Which fire service covers Northwood?
Northwood is in the area of London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
How do you handle parking and loading in Northwood?
London parking can be tight, so details of loading bays and permits help. Working overnight, as we often do in London, typically makes it simpler.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
What does a pre-clean survey involve?
It’s a look at the whole extract before it’s cleaned, with readings and pictures. We can work from photos and details, or visit, as suits the job.
What should I send you?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply call us on 0345 646 2711 or use the quote form.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Ring any time and tell us what’s happened.
Is TR19 cleaning the law?
No. TR19® is not law; it’s BESA’s specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005, which requires the responsible person to reduce fire risk, and TR19® is what insurers and fire officers look to.
Can you work evenings and weekends?
Yes. Much of our work happens in the evening, overnight or at weekends, so you do not have to close during trading.
