Need TR19 inspection in Nash?

What happens if it’s left?

An EHO visit, an insurance renewal or a fire risk assessment is a bad time to find your extract records are thin. An inspection now gives a site in Nash a current picture. A busy site in Nash builds up dirt and wear quickly, so putting it off makes the eventual job larger.

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, give us a ring on 0345 646 2711, or email photos for straight advice and a fixed quote.

What you get with us

  • Out-of-hours work and a 24/7 emergency line

TR19 inspection in Nash

Post-clean verification is a check carried out once the cleaning is done, with fresh grease readings, pictures and a look at the areas that were cleaned. It shows whether the system was left in the condition the paperwork describes. The work covers wet film thickness tests, pre-clean surveys and insurer audits, and people most often call us about systems that need surveying before cleaning and missing access panels found on survey.

In a London area like Nash, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.

It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Staff cleaning versus specialist work

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.

How we price TR19 inspection

Some jobs are bigger than they look, and some smaller. The main factors:

  • When the work can happen, such as evenings, overnight or weekends
  • One-off work versus a regular cycle
  • How many systems or sites are involved
  • The condition we find in the survey

The cost depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

What to send for a quote

To help us quote quickly, please include:

  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • A few general shots of the system
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Any access panels or hatches you can see

Getting a quote does not take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

How the visit works

There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. In Nash, as across London, we normally work overnight or at weekends and hand the site back ready to open.

  1. First we look at the system’s cleaning history, if there is one.
  2. The layout is traced from the canopy to the discharge.
  3. We note where access panels are and where more are needed.
  4. Grease readings are taken and pictures recorded.
  5. You get a report and a fixed quote for the clean.

How to prepare

  • Mention any locked doors, roof access or ceiling voids
  • Find the previous report, if there is one
  • Move anything stored near the system

Ask for a quote

Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Advice

Multi-site and managed buildings

When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.

Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.

Part by part

Vertical risers

Risers carry the extract up through the building. Grease can run down and collect at the base, so we check there.

Horizontal duct runs

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

Keeping the system healthy

Once we have finished, these simple steps help:

  • Keep the route to access panels clear
  • Clean or swap grease filters as often as the kitchen needs
  • Flag oily drips near the extract
  • Keep to the recommended interval

After post-clean verification, file the results with the cleaning certificate. Together they show the system was cleaned and checked.

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

TR19 inspection around Nash

Food Standards Agency records include about 9 bars, pubs and nightclubs in and around Nash, up to about a mile and a half out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. It’s Bromley council that sends environmental health officers to food businesses in Nash. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand. In London, kitchens are usually cleaned overnight, when the kitchen is closed and loading is easier.

Healthcare kitchens, like those at hospitals such as Princess Royal University Hospital (about 1.8 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands. Down House, about 2.4 miles south-east, is one of the historic houses near Nash; if you run event catering at a venue like that, cleans can be booked between functions. Bursars and site managers at schools such as Wickham Common Primary School tend to book extract cleaning for when the kitchen is empty.
