TR19 inspection in Bockhanger

What TR19 inspection cannot fix

TR19 inspection cannot fix everything, and we’d rather say so up front. It will not put right:

  • Sections with no access, until panels are fitted
  • The legal duty, which stays with the responsible person
  • Removing the grease, which is a separate clean

If in doubt, ring 0345 646 2711 or email us and we’ll say what we think.

What the work covers

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

About our TR19 inspection in Bockhanger

BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Those are minimums, and grease readings help set the real interval. Common call-outs are for systems that need surveying before cleaning and systems cleaned on a calendar with no measurements, on access surveys, deposit thickness tests and insurer audits.

Kitchens around a place like Bockhanger are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.

The paperwork matters as much as the work. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

FAQs for Bockhanger

Who enforces fire safety at workplaces in Bockhanger?

Bockhanger is in the area of Kent Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Will you come out to Bockhanger?

Yes. Villages and rural sites across the South East are part of our work, Bockhanger included. Let us know about access, parking and anything unusual about getting there when you book.

What happens to the waste?

We contain it and take it with us. We collect grease, debris and waste water as we go, so it does not spread.

How far ahead should we book?

Earlier is better, especially for out-of-hours work. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.

Do we have to follow TR19 by law?

No. It’s the benchmark rather than the law. In practice, an insurer can refuse or reduce a claim without proof of TR19 cleaning, so it matters in practice.

How often should a kitchen extract be inspected?

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.

Can one contract cover all our sites?

Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.

What is TR19?

A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.

Different parts, different methods

Horizontal duct runs

Bends and long runs can hold heavy deposits, well away from where anyone looks.

Extract fan and discharge

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

What we are called out for in Bockhanger

Grease builds up as cooking vapour cools inside the extract. It often collects where nobody can see it: the plenum, bends and horizontal runs.

Common reasons sites call us include:

  • Confirming a clean reached the whole system
  • Kitchens whose menu or hours have changed
  • Missing access panels found on survey
  • Insurance renewals needing proof of TR19 cleaning

Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Godinton House is about 2.1 miles west), access may need planning.

How to choose an extract cleaning contractor

In-house cleaning or a specialist?

Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.

In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

What happens on the day

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 the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Around Bockhanger, access is usually simpler than in a town centre, though gates and roof access are worth mentioning.

  1. First we book a time that will not disrupt cooking.
  2. We look over the canopy, plenum, ducts, fan and discharge.
  3. Grease thickness is measured at set points by WFTT or DTT.
  4. Each test point and any access problems are photographed.
  5. The findings go into a report with readings, pictures and a recommended next clean.

How to prepare

  • Plan for cooking equipment or plant to be off before we arrive
  • Mention any sign-in, permit or induction we need
  • Clear loose items from the work area

Getting a quote

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Leave it or put it right?

Surveying first means the clean goes to plan. Access problems are spotted in advance rather than on the night, and the quote reflects the real job. A visit arranged in advance is far less disruptive than a callout on a busy day.

The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.

What affects the quote in Bockhanger

Every site gets its own quote. This is what makes a difference:

  • A single visit or a regular plan
  • The scale of the work
  • The times the site is available
  • Any permits to work or inductions

When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before we start.

What we need to know

A few details help us quote accurately. When you get in touch, it helps to send:

  • The roof, plant room or outside wall the system runs to
  • A few general shots of the system
  • Where the site is and what kind of site it is
  • When the site is open and when it’s quiet

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Kitchen extracts in Bockhanger

The FSA’s food hygiene register includes about 7 pubs and bars and about 3 hotels and guest houses within roughly a mile and a half of the centre of Bockhanger. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Food hygiene inspections in Bockhanger are the job of Ashford council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Kent Fire and Rescue Service covers Bockhanger. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

For schools such as Phoenix Community Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. Healthcare kitchens, like those at hospitals such as William Harvey Hospital (about 2.2 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands.
