TR19 inspection near Marlow Common

Part by part

Vertical risers

Risers can be hard to get into. We record what can and can’t be reached.

Canopy and plenum

Filters can look fine while the plenum behind them is heavily coated. That is why we test behind them.

TR19 inspection in Marlow Common

If you’ve taken over a kitchen in Marlow Common and do not know when the extract was last cleaned, an inspection is the place to start. You get readings, pictures and a clear view of what’s needed, so the next step is based on facts. The work covers insurer audits, post-clean checks and access surveys, and the jobs we see most are pre-clean surveys before a first TR19 clean and sites with gaps in their extract records.

Work in a small place like Marlow Common starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.

For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Between visits

A little care between visits keeps the system in better shape. Our advice:

  • Keep grease filters clean and fitted properly
  • Keep canopy edges and gutters wiped down
  • Keep to the recommended interval
  • Keep access panels clear and unpainted

You get a report with the grease readings, where they were taken and pictures of each point. File it alongside your TR19 certificates.

Test grease regularly instead of relying on the calendar. It spots changes in how fast grease builds.

FAQs for Marlow Common

Can the work in Marlow Common be done at night or at weekends?

Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Your opening times are the first thing we ask for.

Which fire authority looks after Marlow Common?

That’s Buckinghamshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

Is there a survey before the work?

Yes. Photos often do the job, and larger or hidden systems get a visit.

Is a quote from pictures possible?

Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.

Do you have a 24/7 line?

Yes. Our emergency line runs 24/7, for problems that can’t wait. Call us any time and explain what’s happened.

What grease levels does TR19 allow?

TR19® Grease says grease should not go over a mean of 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.

How often should a kitchen extract be inspected?

Often enough to know the mean stays under 200 microns between cleans. The readings themselves tell you if the interval needs to change.

Which sectors do you work in?

Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.

Landlords, agents and facilities managers

When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.

Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.

What TR19 inspection looks like in Marlow Common

Food Standards Agency records list about 39 cafés, restaurants and staff canteens and about 8 takeaways and sandwich shops in and around Marlow Common, up to about a mile and a half out. For any of them with a canopy, measuring grease is better than guessing when to clean. Marlow Common sits within the area of Buckinghamshire Fire and Rescue Service. 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. It’s Buckinghamshire council that sends environmental health officers to food businesses in Marlow Common. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

If you run catering at a historic house or estate in the area (Harleyford Manor is about 1.6 miles south), event kitchens in older buildings often have awkward duct runs that need planning. If you look after a school kitchen, at a school such as Spinfield School or anywhere near Marlow Common, the holidays are the usual time for a TR19® clean. A hospital like Marlow Community Hospital, about 1.7 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

What a clean will not put right

Some problems need a different service or another trade:

  • Heavy deposits found on test, which still need cleaning
  • Sections with no access, until panels are fitted
  • The legal duty, which stays with the responsible person

If in doubt, ring 0345 646 2711, or send details by email and we will say what we think.

Parts of the system we cover

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

How it works

Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes an hour or two for a single kitchen, longer for a large or complex system. Pictures of the system and its access let us plan the work in Marlow Common before we set off.

  1. Post-clean verification is booked once the clean is done.
  2. The same access points are opened up.
  3. Grease readings are taken again at set points.
  4. We photograph each area to record how it was left.
  5. We report the findings and flag any areas that need more work.

Before we arrive

  • Mention any locked doors, roof access or ceiling voids
  • Find the previous report, if there is one
  • Allow time for equipment near the work to be turned off and cool down

What affects the cost of TR19 inspection

Before we fix a price, we need to know a few things. We check:

  • The scale of the work
  • Access, including roofs, risers and ceiling voids
  • Where the site is and how we reach it
  • Whether it’s a one-off visit or part of a schedule

We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

Asking for a quote

To speed up the quote, please include:

  • The postcode and the type of business
  • Any previous report or certificate
  • Your opening hours and when the area is out of use
  • A few general shots of the system

Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before work begins.

What happens if it’s left?

Catching heavy deposits early keeps the fix small. Left alone, grease keeps building between cleans. Equipment tucked in a roof space or outbuilding near Marlow Common rarely gets looked at unless someone books it.

The cost depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before work begins, so there are no surprises.

Why Marlow Common businesses choose us

  • Survey first, then a fixed quote
  • A written report with photos after each visit
  • Out-of-hours work and a 24/7 emergency line
  • We are fully insured
