TR19 inspection across Kingsbury

Landlords, agents and facilities managers

We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.

Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.

How we handle TR19 inspection in Kingsbury

Post-clean verification is a check carried out once the cleaning is done, with new readings and photos of the cleaned areas. It shows whether the system was left in the condition the paperwork describes. We are often asked to deal with uncertainty over how often to clean and ductwork where grease may be over the TR19 limits, on pre-clean surveys, wet film thickness tests and post-clean checks.

Kitchens in Kingsbury, 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, which is why keeping it clean to TR19® matters.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Common questions in Kingsbury

Do you clean school canteen extracts around Kingsbury out of term?

Yes, holiday work suits schools best. Around Kingsbury, the Food Standards Agency lists about 30 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.

Which fire authority looks after Kingsbury?

Fire safety enforcement in Kingsbury is handled by 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.

What do you do to protect the area?

By covering it before any work starts. We keep the work contained and leave the area clean.

Is Kingsbury in your area?

Yes. We work in Kingsbury and the rest of Greater London, as part of our work across South East England and London. To book, call us on 0345 646 2711, or send details by email.

Where does the waste go?

Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.

Why survey before a clean?

We survey, measure and photograph the system first. We can work from photos and details, or visit, as suits the job.

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.

Will you produce a report for our insurer?

Yes. We inspect the system and produce a report with grease readings, photos and any inaccessible areas. It’s set out for your insurer or broker.

What we do, step by step

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. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a couple of hours for a typical kitchen extract system. In Kingsbury, as across London, we normally work overnight or at weekends and hand the site back ready to open.

  1. After the clean, we arrange a time to check the system.
  2. The same access points are opened up.
  3. Grease readings are taken again at set points.
  4. Photos are taken to show the condition after the clean.
  5. We report the findings and flag any areas that need more work.

Preparing for the visit

  • Arrange a key holder or contact on site
  • Mention any sign-in, permit or induction we need
  • Dig out any earlier paperwork for the system

TR19 inspection around Kingsbury

According to Food Standards Agency records, there are about 27 pubs, bars and clubs and about 3 hotels, B&Bs and guest houses within roughly a mile and a half of the centre of Kingsbury. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Kingsbury is covered by London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Environmental health officers from Brent council inspect food businesses in Kingsbury. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.

Headstone Manor, about 3.5 miles west, is one of the historic houses near Kingsbury; if you run event catering at a venue like that, cleans can be booked between functions. If you run catering at a healthcare site, such as a hospital like Edgware Community Hospital about 1.6 miles north, the extract may need cleaning more often than a part-time kitchen.

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.

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

What the work involves, part by part

Extract fan and discharge

A greasy fan works harder and wears faster. Readings show if it needs attention before the next clean.

Restaurants, pubs and hotels

Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, and readings show whether that is enough.

Why it’s worth doing now in Kingsbury

Surveying first means the clean goes to plan. Access problems are spotted in advance rather than on the night, so the clean covers the whole system. Shared walls, risers and roofs mean a problem at one London site seldom stays put.

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.

What we are called out for in Kingsbury

Insurers, fire officers and environmental health officers look to TR19® as the benchmark. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and in a kitchen that means keeping grease under control.

What we’re most often called out for:

  • Confirming a clean reached the whole system
  • Heavy grease suspected in the plenum or ducts
  • Missing TR19 certificates or history
  • Pre-clean surveys before a first TR19 clean

If you run a church or community hall kitchen, near Church of the Holy Innocents or elsewhere in Kingsbury, its extract still collects grease from every lunch and event.

What your quote should include

  • Proof of accreditation you can verify
  • How they set the interval to the next visit
  • Whether VAT is included
  • What records you’ll receive afterwards
