TR19 inspection across Slough

TR19 inspection in Slough, done properly

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’re often asked to deal with sites with gaps in their extract records and systems that need surveying before cleaning, on wet film thickness tests, post-clean checks and deposit thickness tests.

In the busier parts of Slough, kitchens are often on the ground floor with flats or offices above, and the extract can climb several storeys before it discharges. A riser needs proper access to be cleaned top to bottom, and any section we can’t reach is recorded on the report.

Every visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Why it’s worth doing now in Slough

Sites in Slough that have never measured grease can’t tell whether their cleaning interval suits the kitchen. Measured readings let a competent person set the interval. Several systems on one site in Slough are simpler to look after when the dates are set in advance.

Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, ring 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.

Slough kitchens: local notes

The FSA’s data shows about 14 pubs, bars and clubs and about 8 hotels, B&Bs and guest houses registered within 1.5 miles or so of the middle of Slough. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Fire safety in Slough falls to Royal Berkshire Fire and Rescue Service. 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 Slough council inspect food businesses in Slough. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready.

Where a hall near St Michael and All Angels, or anywhere in Slough, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you run a café or takeaway near Slough station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

Slough is about 22 miles west of London, in Slough. Every kind of commercial site in Slough, we can take on TR19 inspection. We can work out of hours so trading isn’t interrupted. We cover 31 places across Slough, large and small. You can also see our page for Reading, about 17 miles away.

Every address in SL1, SL3, SL2 and SL6 is covered for TR19 inspection, from the main roads to the quietest streets. Whether your site is on High Street, Station Road and London Road or anywhere close by, our technicians can take on the work.

Multi-site and managed buildings

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

Common questions in Slough

Who enforces fire safety at workplaces in Slough?

That’s Royal Berkshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

Do you clean school canteen extracts around Slough out of term?

Yes, holiday work suits schools best. Around Slough, the Food Standards Agency lists about 20 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.

Is Slough in your area?

Yes. Slough is part of the area we cover, as part of our area across London and the South East.

What is post-clean verification?

Post-clean verification is a check after a clean, with fresh grease readings and pictures. It can follow our own cleans or another contractor’s.

Will you produce a report for our insurer?

Yes. Many insurers ask for proof of TR19 cleaning and inspection, and an audit report gives you that, along with any actions needed.

What about areas you can’t get to?

We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.

Is TR19 cleaning the law?

No. TR19® is BESA’s specification and the industry benchmark, not legislation. The law is the Fire Safety Order 2005, under which the responsible person must manage fire risk, and TR19® is what insurers and fire officers look to.

Do you have a 24/7 line?

Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.

Fixed quotes for TR19 inspection in Slough

A fixed price needs a few facts first. We look at:

  • The times the site is available
  • The number of sites or systems
  • What state the system is in
  • The size of the system

You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, ring 0345 646 2711 or send us an email, and we will explain what it covers.

What to send for a quote

We can often survey from photos. Try to include:

  • The postcode and the type of business
  • The times we could work without disrupting the site
  • Photos showing the whole system and its surroundings
  • The roof, plant room or outside wall the system runs to

If you need TR19 inspection in Slough, phone us on 0345 646 2711, or send details by email. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. A fixed quote usually follows within one working day.

How the visit works

There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. In the busier parts of Slough, parking and roof access are the main things to plan.

  1. First we book a time that won’t disrupt cooking.
  2. We look over the canopy, plenum, ducts, fan and discharge.
  3. We take WFTT or DTT readings at set points along the system.
  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.

Preparing for the visit

  • Mention any locked doors, roof access or ceiling voids
  • Dig out any earlier paperwork for the system
  • Arrange a key holder or contact on site

Ask for a quote

Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before work begins.

What your team can do, and what needs us

Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

Do you need TR19 inspection in Slough?

Not every section of a kitchen extract is easy to get to, and grease can be missed there clean after clean. An inspection of a system in Slough shows where access panels are missing, so the gaps can be closed.

The symptoms we’re asked about most include:

  • Pre-clean surveys before a first TR19 clean
  • Extracts that may be over the 200 micron mean
  • Confirming a clean reached the whole system
  • Kitchen extract systems with no recent grease readings

School kitchens, at schools like Herschel Grammar School for example, are typically cleaned in the holidays so no lunches are lost.

Before booking anyone

  • How they set the interval to the next visit
  • Whether they’re fully insured
  • Whether the whole system is included, or only the parts that are easy to reach
  • What hours they’ll be on site

Choosing a duct cleaning contractor

Aftercare tips

Results last longer with the right care. We suggest:

  • Clean or swap grease filters as often as the kitchen needs
  • Flag oily drips near the extract
  • Flag changes in how much frying the kitchen does
  • Have the latest report ready for insurance renewals

Any access problems we found are listed with a suggested fix. With panels fitted, the next clean can cover every section.

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