Why it’s worth doing now in Gerrards Cross

Skipping grease testing leaves the cleaning interval to guesswork. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, and you can only act on that if you’ve measured it. A visit arranged in advance is far less disruptive than a callout on a busy day.

Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.

How we handle TR19 inspection in Gerrards Cross

BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Grease testing shows whether your kitchen needs cleaning more often than that. We are often asked to deal with sections of duct that can’t be reached and extracts that have never been grease tested, on wet film thickness tests, insurer audits and access surveys.

Size does not change the work: a kitchen in a place like Gerrards Cross gets the whole system cleaned, canopy to discharge. The visit is booked around your opening hours, and the journey is planned ahead.

The paperwork matters as much as the work. Each visit is written up with pictures, 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 ready for an insurer, fire officer or EHO.

What TR19 inspection looks like in Gerrards Cross

The FSA’s data shows about 4 pubs and bars registered within 1.5 miles or so of the middle of Gerrards Cross. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Buckinghamshire Fire and Rescue Service covers Gerrards Cross. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Environmental health officers from Buckinghamshire council inspect food businesses in Gerrards Cross. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready.

Healthcare kitchens, like those at hospitals such as Chalfonts and Gerrards Cross Hospital (about 1.7 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands. If you look after a school kitchen, at a school such as The Gerrards Cross CofE School or anywhere near Gerrards Cross, the holidays are the usual time for a TR19® clean.

Staff cleaning versus specialist work

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

How it works

We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes around an hour or two per canopy and duct system. Tell us about any gates, ladders or locked plant areas at your site near Gerrards Cross when you book.

  1. We go through any past certificates and reports.
  2. We follow the extract from canopy to discharge.
  3. We note where access panels are and where more are needed.
  4. Grease readings are taken and photos recorded.
  5. We report back with readings and a fixed quote.

Before we arrive

  • Mention any sign-in, permit or induction we need
  • Mention any locked doors, roof access or ceiling voids
  • Clear loose items from the work area

Ask for a quote

Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before we start.

Advice

What we are called out for in Gerrards Cross

Looking at a canopy tells you little about what’s in the duct. A system can look clean at the filters and be heavily coated further in, which is why readings matter.

These are the problems we see most often:

  • Uncertainty over how often to clean
  • Sites with gaps in their extract records
  • Insurers asking for TR19 evidence
  • Ductwork where grease may be over the TR19 limits

Volunteers running a hall kitchen near St James Church, or anywhere in Gerrards Cross, may not know when the extract was last cleaned, and a grease test settles it.

Before you book anyone

  • Whether VAT is included
  • What paperwork you get at the end
  • Exactly which parts of the system are covered
  • Proof of accreditation you can verify

How to choose an extract cleaning contractor

Common questions in Gerrards Cross

Can a school canteen extract in Gerrards Cross be done out of term time?

Yes, holiday work suits schools best. Food Standards Agency records list about 9 schools, colleges and universities with registered kitchens within about a mile and a half of Gerrards Cross. Send us your term dates when you give us a ring on 0345 646 2711 or use the quote form, and we will fit the work in.

Who enforces fire safety at workplaces in Gerrards Cross?

Gerrards Cross is in the area of Buckinghamshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.

What does TR19 mean?

BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.

How far ahead should we book?

That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.

Why survey before a clean?

The survey covers the whole system, grease readings and access to each section. It lets us plan the clean and give you a fixed quote.

Do you work with multi-site operators?

Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.

Can you set up regular visits?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.

Can you price the work without visiting?

Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we usually come back within one working day. Some sites still need a visit, and we will say so.

What affects the cost of TR19 inspection

Your quote is based on your site. We take into account:

  • The times the site is available
  • Whether it’s a one-off visit or part of a schedule
  • Access, including roofs, risers and ceiling voids
  • The condition we find in the survey

A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before we start.

Helping us quote

There’s no need for technical detail. It helps if you can send:

  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • A few general shots of the system
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Your opening hours and when the area is out of use

Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then phone us on 0345 646 2711, or send details by email.

Looking after it afterwards

To keep the system working properly between visits:

  • Flag oily drips near the extract
  • Keep access panels clear and unpainted
  • Keep canopy edges and gutters wiped down
  • Keep to the recommended interval

You get a report with the grease readings, where they were taken and photos of each point. Keep it with your fire safety and TR19 records.

Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.

Honest limits

Not every problem is solved by TR19 inspection, and we’d rather say so up front. It won’t put right:

  • Design faults in the extract system
  • The legal duty, which stays with the responsible person
  • Hidden runs that need access panels first

If you are not sure, just ring 0345 646 2711 or email us and we will give you a straight answer before booking.
