TR19 Inspection in North Harrow
Our technicians work in North Harrow on TR19 inspection. Out-of-hours visits, a fixed quote and a written report with photos as standard.
- Parts of the system left out of past cleans
- Extracts that may be over the 200 micron mean
- Checking the result of a recent clean
In-house cleaning or a specialist?
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
TR19 inspection for kitchens and businesses in North Harrow
A fixed schedule doesn’t always match how a kitchen really cooks. Some kitchens build up grease faster than the minimum intervals assume, and only measurement shows it. Our readings give your risk assessment real numbers to work from. If you have sites with gaps in their extract records and extracts that may be over the 200 micron mean, we can put it right.
Kitchens in North Harrow, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

The process
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes an hour or two for a single kitchen, longer for a large or complex system. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in North Harrow.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- Grease readings are taken again at set points.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Let us know when the site is closed or quiet
- Dig out any earlier paperwork for the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
How to get a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

Common problems we fix in North Harrow
As hot, greasy air travels up the duct, it cools and leaves a film behind. It often collects where nobody can see it: the plenum, bends and horizontal runs.
What we’re most often called out for:
- Extracts that have never been grease tested
- Ductwork where grease may be over the TR19 limits
- Surveys needed before quoting a full clean
- Insurance renewals needing proof of TR19 cleaning
A hospital like Northwick Park Hospital, about 1.9 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Questions to ask before booking
- Whether the quote is based on a survey or pictures
- Proof of accreditation you can verify
- What paperwork you get at the end
- Whether they’re fully insured
What TR19 inspection can’t fix
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Fire safety duties beyond the extract system
- Parts of the duct nobody can reach yet
- The grease itself, which needs a full or spot clean
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we’ll tell you honestly.
What we work on in North Harrow
- Wet film thickness tests

Landlords, agents and facilities managers
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

What the work involves, part by part
Horizontal duct runs
If a run has no access panel, we note it so it can be fixed before the clean.
Canopy and plenum
The plenum behind the filters can carry a lot of grease. We take readings there and photograph it on every inspection.
Your questions about TR19 inspection in North Harrow
Which council inspects kitchens in North Harrow?
Food hygiene inspections in North Harrow are carried out by Harrow council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you work overnight in North Harrow?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Just call us on 0345 646 2711, or email photos with your opening times and we will plan around them.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
Do you offer emergency callouts?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Do you carry out TR19 audits for insurers?
Yes. Our TR19 audits cover readings, pictures, access and a recommended cleaning interval. It’s set out for your insurer or broker.
Do you check other contractors’ cleans?
We visit after a clean, take readings at set points and photograph the system. Any areas that weren’t cleaned properly are flagged.
Is a quote from photos possible?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Why act early in North Harrow
A check after cleaning shows whether the work reached every part it should have, before the next clean is due. In North Harrow, a planned overnight visit is much easier than closing unexpectedly.
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before work begins.

North Harrow kitchens: local notes
There are about 272 cafés, restaurants and staff canteens and about 118 takeaways and sandwich shops within about 1.5 miles of central North Harrow, according to the Food Standards Agency’s register. Each kitchen extract among them can be measured for grease to set the right cleaning interval. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected. North Harrow is covered by 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.
Term dates shape school work: for a school like Longfield Primary School, an extract clean fits neatly into a half-term or summer break. If you run catering at a historic house or estate in the area (Headstone Manor is about 0.8 miles north-east), event kitchens in older buildings often have awkward duct runs that need planning.
North Harrow is about 1 mile north-west of Harrow, in Greater London.
