TR19 inspection across Penn Street

What we’re called out for in Penn Street

Records can go missing when a business changes hands or contractors. Without them, nobody knows how much grease is in the system or when it was last cleaned.

Any of these means the system needs a check-up:

  • Sections of duct that can’t be reached
  • Insurance renewals needing proof of TR19 cleaning
  • Sites with gaps in their extract records
  • Post-clean verification after another contractor’s clean

A hospital like Amersham Hospital, about 1.8 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Questions to ask before booking

  • Exactly which parts of the system are covered
  • Which accreditations they hold, and whether you can check them
  • Whether the work can be done while the site is closed
  • How they set the interval to the next visit

Questions to ask before you book

About our TR19 inspection in Penn Street

A grease test measures how thick the grease is inside a kitchen extract system. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. The results show whether the system needs cleaning and how soon. The work covers deposit thickness tests, wet film thickness tests and access surveys, and common reasons people get in touch are post-clean verification after another contractor’s clean and sections of duct that can’t be reached.

Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.

Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Why act early in Penn Street

Without readings, you are guessing when to clean. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, which you will not know without measuring. Systems in rural buildings are often out of sight and out of mind.

Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.

Take a look at what affects the cost or our accreditations.

What the work involves, part by part

Extract fan and discharge

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

Restaurants, pubs and hotels

Inspections are done when the kitchen is closed or quiet so the kitchen keeps cooking.

What happens on the day

There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, which takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. A quick note on how to find the site and where to park makes a visit to Penn Street run smoothly.

  1. We go through any past certificates and reports.
  2. The layout is traced from the canopy to the 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.

Before we arrive

  • Name a contact who can let us in at the agreed time
  • Agree a time when the area can be out of use
  • Tell us where we can park and unload

Ask for a quote

Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

FAQs for Penn Street

Do you clean school canteen extracts around Penn Street out of term?

Yes, holiday work suits schools best. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Penn Street, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.

Who would carry out a food hygiene inspection at a kitchen in Penn Street?

That is Buckinghamshire council, whose environmental health officers carry out food hygiene inspections in Penn Street. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.

When should we have our next grease test?

We suggest a next test date in every report, taking the readings and the kitchen’s hours into account. A risk assessment based on measured grease should set the interval.

Do you cover Penn Street?

Yes. Our technicians work in Penn Street, as part of our area across London and the South East.

Do you work out of hours?

Yes. Tell us your opening hours when you ask for a quote and we’ll book around them.

What does TR19 inspection cost?

We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.

Can you price the work without visiting?

Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.

Do you offer emergency callouts?

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

Managing agents and facilities teams in Penn Street

Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.

Fixed quotes for TR19 inspection in Penn Street

You will get a fixed price before work begins. It’s based on:

  • The scale of the work
  • What state the system is in
  • How easy every part is to reach
  • Site requirements such as sign-in and permits

What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before work begins.

Asking for a quote

The more you tell us, the more accurate the quote. When you get in touch, it helps to send:

  • Close-ups of filters, grilles, hatches or access panels
  • Any symptoms, from odd noises to smells or leaks
  • The site address and the type of premises
  • The times we could work without disrupting the site

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.

Keeping the system healthy

To keep the system working properly between visits:

  • Send TR19 audit reports to your insurer on request
  • Keep TR19 certificates, readings and reports together
  • Flag oily drips near the extract
  • Keep the route to access panels clear

Keep the verification report next to the certificate it relates to. Together they show the system was cleaned and checked.

Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.

According to Food Standards Agency records, there are about 4 pubs and bars in and around Penn Street, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. It’s Buckinghamshire council that sends environmental health officers to food businesses in Penn Street.
