Multi-site and managed buildings

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.

TR19 inspection for kitchens and businesses in South Harrow

Think of a TR19 inspection as the diagnosis before the treatment. We look at the system, take grease readings and photograph what we find, so the clean can be planned properly. Common call-outs are for extracts that may be over the 200 micron mean and insurers asking for TR19 evidence, across post-clean checks, wet film thickness tests and deposit thickness tests.

London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. For a kitchen in South Harrow, that typically means a longer system to clean and more access panels to plan around.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Keeping the system healthy

Results last longer with the right care. Here’s what we suggest:

  • Clean or swap grease filters as often as the kitchen needs
  • Diary the next grease test and clean
  • Clean grease off the canopy between professional cleans
  • Send TR19 audit reports to your insurer on request

The audit report is set out to pass straight to your insurer or broker, with readings, pictures and any areas not accessible.

Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.

Do you need TR19 inspection in South Harrow?

Grease is fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Knowing how much there is lets you act before it becomes a hazard.

Common reasons sites call us include:

  • Systems that need surveying before cleaning
  • Extracts that may be over the 200 micron mean
  • Insurance renewals needing proof of TR19 cleaning
  • Parts of the system left out of past cleans

Volunteers running a hall kitchen near Parish Church of St Paul, or anywhere in South Harrow, may not know when the extract was last cleaned, and a grease test settles it.

Before booking anyone

  • Whether the whole system is included, or only the parts that are easy to reach
  • Whether inaccessible sections are listed on the report
  • If the quote is a fixed price or an estimate
  • When they can work, and whether that is outside your opening hours

Our hiring checklist

What TR19 inspection can’t fix

We will not sell you work that doesn’t address the problem, so here are the limits:

  • Ductwork that was designed or installed badly
  • The grease itself, which needs a full or spot clean
  • The responsible person’s own fire risk assessment

Not sure which it is? You can call 0345 646 2711 or drop us a line and we will tell you honestly.

What the work covers

  • Access surveys
  • Wet film thickness tests
  • Insurer audits
  • Pre-clean surveys
  • Post-clean checks
  • Deposit thickness tests

Staff cleaning versus specialist work

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.

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

How it works

We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a couple of hours for a typical kitchen extract system. For a job in South Harrow, tell us about loading bays, permits, lifts and roof access when you book.

  1. First we look at the system’s cleaning history, if there is one.
  2. We follow the extract from canopy to discharge.
  3. We note where access panels are and where more are needed.
  4. We measure the grease and photograph each point.
  5. We report back with readings and a fixed quote.

How to prepare

  • Tell us about site rules, permits or sign-in
  • Make sure equipment near the work can be switched off and left to cool
  • Let us know how we reach the system, including roofs, risers and plant rooms

Advice

South Harrow questions

Can you clean school kitchen extracts in South Harrow during the holidays?

Yes. The holidays are the usual time for school work. With about 21 schools and colleges on the FSA’s register within roughly a mile and a half of South Harrow, it pays to plan holiday dates ahead. Send us your term dates when you call 0345 646 2711 or send us an email, and we’ll fit the work in.

How do you handle parking and loading in South Harrow?

Tell us where a van can stop near your site in South Harrow, and about any building rules on loading. Where restrictions apply in the day, an evening or overnight visit usually gets round them.

How much does TR19 inspection cost in South Harrow?

The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we’ll typically reply within one working day.

Do you look at the system first?

Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.

How long does grease testing take?

An inspection takes an hour or two for a single kitchen, longer for a large or complex system. Sites with several canopies take longer, so phone us on 0345 646 2711 or send us an email and we will plan it.

Can you work evenings and weekends?

Yes, and it’s often the best time. We book the visit for when the area is out of use, whether that is late evening, overnight or a weekend.

What do you need from me for a quote?

Some photos and a quick description of the system, with the address and opening hours. We will ask for anything else we need.

Why survey before a clean?

It’s a look at the whole extract before it’s cleaned, with readings and photos. We can work from photos and details, or visit, whichever suits the system.

How the job changes from site to site

Extract fan and discharge

We look at where the extract discharges outside, as grease can build up there too.

Schools, hospitals and care homes

Inspections are planned around mealtimes and holidays so meals aren’t affected.

Kitchen extracts in South Harrow

The FSA’s food hygiene register includes about 30 pubs, bars and clubs and about 4 hotels and B&Bs in and around South Harrow, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier. Kitchens in South Harrow get their food hygiene inspections from Harrow council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready.

A hospital like Clementine Churchill Hospital, about 0.9 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Bursars and site managers at schools such as The Welldon Park Academy tend to book extract cleaning for when the kitchen is empty.
