TR19 inspection for kitchens and businesses in Maple Cross

After a clean, post-clean verification checks the result, with new readings and photos of the cleaned areas. It shows whether the system was left in the condition the paperwork describes. Typical jobs include kitchens whose menu or hours have changed and ductwork where grease may be over the TR19 limits, on access surveys, post-clean checks and wet film thickness tests.

For a kitchen in or near Maple Cross, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.

Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Do you need TR19 inspection in Maple Cross?

When a site in Maple Cross changes owner or cleaning contractor, the records don’t always follow. With no history, the current state of the extract is a guess.

Clients typically contact us when they notice one of these:

  • Uncertainty over how often to clean
  • Missing access panels found on survey
  • Checking the result of a recent clean
  • Insurance renewals needing proof of TR19 cleaning

Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Maple Cross is Harefield Hospital, about 1.7 miles south-east.

Our hiring checklist

How the visit works

The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, which takes an hour or two for a single kitchen, longer for a large or complex system. Rural roads and tight entrances are worth telling us about before a visit to Maple Cross.

  1. First we look at the system’s cleaning history, if there is one.
  2. We follow the extract from canopy to discharge.
  3. Access panels are located and any missing ones noted.
  4. We measure the grease and photograph each point.
  5. You get a report and a fixed quote for the clean.

Preparing for the visit

  • Let us know about permits to work or site inductions
  • Make sure equipment near the work can be switched off and left to cool
  • Move anything stored near the system

Getting a quote

Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Your questions about TR19 inspection in Maple Cross

Who carries out food hygiene inspections in Maple Cross?

Kitchens in Maple Cross are inspected by Three Rivers council’s environmental health officers. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.

Do you clean school canteen extracts around Maple Cross out of term?

Yes, and it’s the easiest time to do it. Food Standards Agency records list about 4 schools, colleges and universities with registered kitchens within about a mile and a half of Maple Cross. Booking early in the term gives the best choice of holiday dates.

Do you look at the system first?

Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.

Is Maple Cross in your area?

Yes. Our area takes in London and the counties of South East England, and that includes Maple Cross.

How do you keep the site clean during the work?

Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.

Is TR19 cleaning the law?

No. TR19® is BESA’s specification and the industry benchmark, not legislation. The law is the Fire Safety Order 2005, under which the responsible person must manage fire risk, and TR19® is what insurers and fire officers look to.

What accreditations do you have?

BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we’re fully insured.

Can we book visits on a schedule?

Yes. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.

Aftercare tips

Results last longer with the right care. We suggest:

  • Never cook with filters missing
  • Keep TR19 certificates, readings and reports together
  • Book the next test on the date in the report
  • Wipe the canopy surfaces regularly

Where sections couldn’t be reached, the report says where access panels would help. With panels fitted, the next clean can cover every section.

Regular grease readings keep the cleaning interval honest. It shows if build-up is speeding up.

TR19 inspection around Maple Cross

The Food Standards Agency lists about 5 pubs and bars as registered food businesses within 1.5 miles or so of the middle of Maple Cross. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Fire safety in Maple Cross falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Maple Cross, food businesses are inspected by environmental health officers from Three Rivers council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after pictures from each clean are a simple way to show the extract is in hand.

Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Chenies Manor House is about 3.7 miles north), access may need planning. Volunteers running a hall kitchen near Church of St Thomas of Canterbury, or anywhere in Maple Cross, may not know when the extract was last cleaned, and a grease test settles it.

Why act early in Maple Cross

A pre-clean survey avoids surprises on the night. Access problems are spotted in advance rather than on the night, so the clean covers the whole system. If the system at a site near Maple Cross fails, there may be nowhere nearby to move to.

When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before work begins.

What you get with us

  • CHAS, SafeContractor and ISO 9001
  • We diagnose before we treat
  • Member of BESCA Vent Hygiene Elite, cleaning to BESA TR19® Grease
  • A fixed price before any work starts

Multi-site and managed buildings

We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Larger estates can be phased building by building to keep disruption down.

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.

How the job changes from site to site

Extract fan and discharge

The discharge at the end of the system is checked as well, as grease can build up there too.

Schools, hospitals and care homes

Inspections are planned around mealtimes and holidays to avoid disruption.
