TR19 inspection near North Cheam

TR19 inspection in North Cheam

TR19® Grease says grease should not exceed a mean of 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Testing is how you know where your system stands. If you have parts of the system left out of past cleans and checking the result of a recent clean, we can help.

London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. In North Cheam, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.

Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Fixed quotes for TR19 inspection in North Cheam

The survey tells us what the work involves. The main factors are:

  • What state the system is in
  • The times the site is available
  • One-off work versus a regular cycle
  • Access, including roofs, risers and ceiling voids

The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.

What to send for a quote

Photos and a few facts are often enough to price the work. Send what you can of the following:

  • Where the site is and what kind of site it is
  • Photos showing the whole system and its surroundings
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Any access panels or hatches you can see

To get a fixed quote, phone us on 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We normally come back within one working day.

What we do, step by step

The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes anything from an hour for a small canopy and short duct to a good part of a day for a large site, and the area is cleaned down before we leave. In North Cheam, as across London, we normally work overnight or at weekends and hand the site back ready to open.

  1. The visit is arranged for when the kitchen is not busy.
  2. We look over the canopy, plenum, ducts, fan and discharge.
  3. Grease thickness is measured at set points by WFTT or DTT.
  4. Photos are taken at each point, and access gaps noted.
  5. You get a report with readings, photos and recommendations.

Getting ready for the visit

  • Tell us where we can park and unload
  • Clear loose items from the work area
  • Agree a time when the area can be out of use

Ask for a quote

Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before we start.

Landlords, agents and facilities managers

From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.

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

Honest limits

A few issues sit outside what this work can do:

  • Sections with no access, until panels are fitted
  • A faulty or failing extract fan
  • Heavy deposits found on test, which still need cleaning

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

What the work covers

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

Grease, kitchens and North Cheam

The FSA’s data shows about 27 bars, pubs and nightclubs registered across North Cheam and its immediate surroundings (about a mile and a half). Any of them serving cooked food has an extract to keep clean, from canopy to discharge. The fire and rescue service for North Cheam is London Fire Brigade. 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. Kitchens in North Cheam get their food hygiene inspections from Sutton council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.

If you look after a school kitchen, at a school such as Cheam Park Farm Primary Academy or anywhere near North Cheam, the holidays are the usual time for a TR19® clean. Healthcare kitchens, like those at hospitals such as St. Anthony's Hospital (about 0.6 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands. If you run a church or community hall kitchen, near St Oswald Church or elsewhere in North Cheam, its extract still collects grease from every lunch and event.

North Cheam is about 3 miles north-east of Epsom, in Greater London.

Questions from North Cheam

Can a school canteen extract in North Cheam be done out of term time?

Yes, out-of-term visits are normal for schools. The FSA’s register shows about 28 schools and colleges with food registrations within roughly a mile and a half of North Cheam. You can ring 0345 646 2711 or send us an email with the dates the site is empty.

Do you work at weekends in North Cheam?

Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in North Cheam needn’t be disturbed. Just call us on 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.

How do you measure grease in a kitchen extract?

Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, and set against the TR19® Grease figures.

Do you work in North Cheam?

Yes. Our technicians work in North Cheam, as part of our area across London and the South East.

How often should grease be tested?

Each report recommends when to test and clean next, based on the readings and how the kitchen is used. A risk assessment based on measured grease should set the interval.

What is post-clean verification?

It’s an inspection after cleaning, to show what state the system was left in, for our cleans and other firms’ alike.

Is TR19 a legal requirement?

No. TR19® is BESA’s specification and the industry benchmark, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005, which requires the responsible person to reduce fire risk, and TR19® is what insurers and fire officers look to.

What happens on a pre-clean survey?

We survey, measure and photograph the system first. We can work from photos and details, or visit, as suits the job.

Staff cleaning versus specialist work

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.

Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

Different parts, different methods

Restaurants, pubs and hotels

We test between services, early in the morning or after close so the kitchen keeps cooking.

Schools, hospitals and care homes

Education kitchens need TR19 inspections like any other. Readings show if the interval is right.

Why deal with it now?

Without readings, you are guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, and you can only act on that if you’ve measured it. In North Cheam, as across London, ductwork often passes through shared risers and other people’s space.

Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.
