About our TR19 inspection in Aston Clinton

Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Testing is how you know where your system stands. We are often asked to deal with missing access panels found on survey and insurers asking for TR19 evidence, across deposit thickness tests, insurer audits and access surveys.

Size doesn’t change the work: a kitchen in a place like Aston Clinton gets the whole system cleaned, canopy to discharge. The visit is booked around your opening hours, and the journey is planned ahead.

Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Staff cleaning versus specialist work

Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

Grease, kitchens and Aston Clinton

There are about 7 restaurants, cafés and works canteens across Aston Clinton and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Kitchens in Aston Clinton get their food hygiene inspections from Buckinghamshire council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Aston Clinton falls to Buckinghamshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Stoke Mandeville Hospital is the nearest hospital to Aston Clinton, about 3.2 miles west. Historic houses near Aston Clinton, such as Cholesbury Manor House about 4.5 miles south-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Leave it or put it right?

If there’s a fire or a claim, your insurer may ask for TR19 records. Missing records can put a claim at risk. Getting an inspection done now starts that paper trail. A planned visit to Aston Clinton fits your hours; an emergency does not.

No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

Managing agents and facilities teams in Aston Clinton

Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.

From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

Different parts, different methods

Horizontal duct runs

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

Restaurants, pubs and hotels

We test between services, early in the morning or after close so trading is not affected.

Fixed quotes for TR19 inspection in Aston Clinton

We quote each job individually. This is what makes a difference:

  • Site requirements such as sign-in and permits
  • Travel, parking and unloading
  • Whether we need access equipment or extra panels
  • The number of sites or systems

Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we’ll price it together.

What to send for a quote

When you contact us, these details help:

  • A few general shots of the system
  • The paperwork from the last visit, if you have it
  • When the site is open and when it’s quiet
  • Problems your staff have spotted

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.

Your questions about TR19 inspection in Aston Clinton

Can you work in Aston Clinton outside opening hours?

Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Aston Clinton needn’t be disturbed. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.

Is Aston Clinton within the area you cover?

Yes, we work in villages as well as towns, and Aston Clinton is covered. Just mention lanes, gates or anything else about the site when you book.

How do you keep the site clean during the work?

We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.

How often should a kitchen extract be inspected?

It depends on how heavily the kitchen cooks. BESA sets minimum cleaning intervals of 3, 6 or 12 months by daily use, and grease readings help set the real interval.

How do you measure grease in a kitchen extract?

The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. Readings are taken at set points through the system.

How much notice should we give?

It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.

What do the grease readings need to be?

TR19® Grease says grease should not go over a mean of 200 microns between cleans. 500 microns or more at any point calls for immediate spot cleaning.

Are you accredited?

We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.

What we’re called out for in Aston Clinton

Some parts of a system are hard to reach, and grease can be missed there clean after clean. A survey finds the sections that can’t be reached, so the gaps can be closed.

Common reasons sites call us include:

  • Kitchens whose menu or hours have changed
  • Extracts that may be over the 200 micron mean
  • Extracts that have never been grease tested
  • Insurers asking for TR19 evidence

School kitchens, at schools like Aston Clinton School for example, are usually cleaned in the holidays so no lunches are lost.

Comparing quotes

  • Whether the quote is based on a survey or pictures
  • Whether the figure could change on the day
  • How areas they cannot reach will be recorded
  • Which accreditations they hold, and whether you can check them

How to choose an extract cleaning contractor

The process

At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes an hour or two for a single kitchen, longer for a large or complex system. In a smaller place like Aston Clinton, parking is rarely the issue, but tell us about gates, roof access and opening hours.

  1. We go through any past certificates and reports.
  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 photos recorded.
  5. You get a report and a fixed quote for the clean.

Before we arrive

  • Name a contact who can let us in at the agreed time
  • Allow time for equipment near the work to be turned off and cool down
  • Mention any locked doors, roof access or ceiling voids

Getting a quote

Getting a quote doesn’t take long. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
