Need TR19 inspection in Rickmansworth?

What we do, step by step

When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes a morning or less for one kitchen, more where there are several systems. In a town like Rickmansworth, we typically work after closing or on a quiet day, so the site opens again on time.

  1. After the clean, we arrange a time to check the system.
  2. We open the access points used on the clean.
  3. Grease readings are taken again at set points.
  4. Photos are taken to show the condition after the clean.
  5. We report the findings and flag any areas that need more work.

Getting ready for the visit

  • Agree a time when the area can be out of use
  • Make sure someone can let us in and lock up afterwards
  • Find the previous report, if there is one

Ask for a quote

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 pictures, get a survey first. Either way, you get a fixed price before we start.

TR19 inspection in Rickmansworth

A fixed schedule does not always match how a kitchen really cooks. 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 cleaning intervals that may not suit the kitchen and surveys needed before quoting a full clean, on insurer audits, access surveys and post-clean checks.

For a pub, café or restaurant in a town like Rickmansworth, losing a day’s trade to cleaning is not an option, so cleans are booked after closing, early in the morning or on a quiet day. The kitchen is handed back clean and ready to cook.

It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What your team can do, and what needs us

Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

What a clean won’t put right

A few issues sit outside what this work can do:

  • Hidden runs that need access panels first
  • A faulty or failing extract fan
  • The grease itself, which needs a full or spot clean

If in doubt, call 0345 646 2711 or email us and we will say what we think before booking.

Parts of the system we cover

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

For landlords and multi-site operators

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

For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.

Kitchen extracts in Rickmansworth

The FSA’s data shows about 18 bars, pubs and nightclubs and about 3 hotels, B&Bs and guest houses registered within roughly a mile and a half of the centre of Rickmansworth. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. It’s Three Rivers council that sends environmental health officers to food businesses in Rickmansworth. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked. Rickmansworth is covered by Hertfordshire 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.

Term dates shape school work: for a school like Saint Joan of Arc Catholic School, an extract clean fits neatly into a half-term or summer break. For kitchens close to Rickmansworth station, where the day often starts early and ends late, the extract can be cleaned overnight.

Looking after it afterwards

A little care between visits keeps the system in better shape. We recommend:

  • Report grease dripping from the canopy
  • Keep TR19 certificates, readings and reports together
  • Wipe the canopy surfaces regularly
  • Share inspection reports with your insurer or broker when asked

After the inspection, we send a report showing each reading, its location and photos. File it alongside your TR19 certificates.

Fit access panels where the survey finds sections can’t be reached, so grease isn’t left building in hidden parts.

Signs you need TR19 inspection in Rickmansworth

TR19® is the benchmark that insurers, fire officers and EHOs refer to. It isn’t legislation; the legal duty comes from the Fire Safety Order 2005, under which the responsible person must reduce fire risk, and in a kitchen that means keeping grease under control.

Common reasons sites call us are:

  • Ductwork where grease may be over the TR19 limits
  • Pre-clean surveys before a first TR19 clean
  • Sections of duct that cannot be reached
  • Insurers asking for TR19 evidence

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Bishops Wood Hospital is the nearest hospital to Rickmansworth, about 1.9 miles south-east.
