TR19 inspection across Ditton Hill

What TR19 inspection can’t fix

A few issues sit outside what this work can do:

  • The grease itself, which needs a full or spot clean
  • Installation problems, which fall under design guidance such as DW172
  • Hidden runs that need access panels first

About our TR19 inspection in Ditton Hill

Not every kitchen fits neatly into a calendar. Some kitchens build up grease faster than the minimum intervals assume, which is why measurement matters. We give your risk assessment measured figures rather than guesses. Typical jobs include missing TR19 certificates or history and kitchens whose menu or hours have changed, on post-clean checks, insurer audits and pre-clean surveys.

London kitchens tend to trade late and open early, so extract cleaning in Ditton Hill is usually done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.

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

How the job changes from site to site

Restaurants, pubs and hotels

Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, with testing showing whether more is needed.

Horizontal duct runs

Flat duct runs collect grease along their base. We test at points along the run through access panels.

FAQs for Ditton Hill

Can a school canteen extract in Ditton Hill be done out of term time?

Yes. The holidays are the usual time for school work. Food Standards Agency records list about 28 schools, colleges and universities with registered kitchens within about a mile and a half of Ditton Hill. Send us your term dates when you phone us on 0345 646 2711 or send us an email, and we will fit the work in.

Which fire authority looks after Ditton Hill?

That is London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Do you offer emergency callouts?

Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.

Which kinds of sites do you work on?

All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.

What happens if you can’t reach some of it?

They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.

What accreditations do you have?

We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Do we have to follow TR19 by law?

No, TR19® isn’t legislation. The Fire Safety Order 2005 still requires the responsible person to manage fire risk, and grease in the extract is part of that. Many insurers also expect TR19 cleaning.

Do you look at the system first?

Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.

Why it’s worth doing now in Ditton Hill

Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Left alone, grease keeps building between cleans. In Ditton Hill, a planned overnight visit is much easier than closing unexpectedly.

What you pay reflects the actual work. That is why we survey first, from photos or on site, and why the quote is fixed before work begins.

For landlords and multi-site operators

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

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

When to call us in Ditton Hill

Grease in a duct is flammable fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Measuring it is the first step to keeping it under control.

Most sites get in touch after spotting something like this:

  • Sections of duct that cannot be reached
  • Extracts that have never been grease tested
  • Pre-clean surveys before a first TR19 clean
  • Post-clean verification after another contractor’s clean

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

What to look for in a quote

  • What hours they’ll be on site
  • Whether a written report and pictures are included
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • Whether inaccessible sections are listed on the report

Questions to ask before you book

What happens on the day

At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit 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 Ditton Hill.

  1. First we book a time that will not disrupt cooking.
  2. Every part of the system is examined, end to end.
  3. Grease thickness is measured at set points by WFTT or DTT.
  4. Photos are taken at each point, and access gaps noted.
  5. We send a report setting out the readings, photos and next steps.

Preparing for the visit

  • Make sure equipment near the work can be switched off and left to cool
  • Let us know about parking and loading
  • Let us know about permits to work or site inductions

Kitchen extracts in Ditton Hill

The Food Standards Agency lists about 35 bars, pubs and nightclubs and about 5 hotels, B&Bs and guest houses as registered food businesses in and around Ditton Hill, up to about a mile and a half out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. In London, kitchens are usually cleaned overnight, when the kitchen is closed and loading is easier. Ditton Hill sits within the area of 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.

If your kitchen is in a listed or historic building, like the houses around Ditton Hill (Hampton Court Palace is about 2 miles north-west), fitting access panels needs care. For schools such as Long Ditton Infant and Nursery School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Keeping the system healthy

So the system stays in good health:

  • Keep TR19 certificates, readings and reports together
  • Clean or swap grease filters as often as the kitchen needs
  • Diary the next grease test and clean
  • Report grease dripping from the canopy

For an insurer audit, send them the report as it is, with readings, pictures and any areas not accessible.

Keep all TR19 records together so the history is easy to show.
