TR19 inspection for sites in Longford

TR19 inspection in Longford

Before any clean in Longford, we survey the canopy, plenum, filters, ducts, fan and discharge. Access is checked along the full length, and record grease readings at set points. Common call-outs are for uncertainty over how often to clean and kitchen extract systems with no recent grease readings, across insurer audits, post-clean checks and wet film thickness tests.

For a kitchen in or near Longford, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.

For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Part by part

Restaurants, pubs and hotels

Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, and readings show whether that’s enough.

Vertical risers

Risers carry the extract up through the building. Grease can run down and collect at the base, so the base is a key test point.

Honest limits

Some problems need a different service or another trade:

  • Hidden runs that need access panels first
  • Removing the grease, which is a separate clean
  • The responsible person’s own fire risk assessment

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

Where we work

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

What staff can safely do

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.

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.

Grease, kitchens and Longford

The FSA’s food hygiene register shows about 70 cafés, restaurants and staff canteens and about 8 takeaways in Longford and the streets around it, up to about 1.5 miles out. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. The fire and rescue service for Longford is 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. In Longford, food businesses are inspected by environmental health officers from Hillingdon council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand.

If you run catering at a healthcare site, such as a hospital like Harlington about 2.1 miles north-east, the extract may need cleaning more often than a part-time kitchen. Commuter trade near Heathrow Terminal 5 Rail station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

Common questions in Longford

Which council inspects kitchens in Longford?

That is Hillingdon council, whose environmental health officers carry out food hygiene inspections in Longford. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.

Who enforces fire safety at workplaces in Longford?

That is Royal Berkshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

Do you cover Longford?

Yes. We cover Longford and the rest of Slough, as part of our work across South East England and London. For a fixed quote, call 0345 646 2711 or drop us a line.

What happens on a pre-clean survey?

We survey, measure and photograph the system first. The survey can be done from photos and details or on site, whichever suits the system.

Can you set up regular visits?

Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.

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.

What grease levels does TR19 allow?

TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, with 500 microns or more anywhere needing immediate spot cleaning.

What accreditations do you have?

BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we are fully insured.

How it works

There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes around an hour or two per canopy and duct system. We agree a date with you, plan the drive to Longford and turn up when the site is quiet.

  1. The visit is arranged for when the kitchen is not busy.
  2. Every part of the system is examined, end to end.
  3. Grease thickness is measured at set points by WFTT or DTT.
  4. Photos are taken at each point, and access gaps noted.
  5. We send a report setting out the readings, photos and next steps.

Preparing for the visit

  • Clear the space around the work
  • 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

Ask for a quote

Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Advice

Signs you need TR19 inspection in Longford

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

Most sites get in touch when they notice something like this:

  • Systems that need surveying before cleaning
  • Extracts that have never been grease tested
  • Missing TR19 certificates or history
  • Uncertainty over how often to clean

Church and community hall kitchens, near Church of St Mary or anywhere around Longford, are easy to forget, but their extracts collect grease like any other.

Choosing a duct cleaning contractor

Why deal with it now?

Post-clean verification shows whether the system was left the way the certificate says, while there’s still time to put anything right. Out of sight is the usual reason a rural system goes too long without attention.

What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before we start.

What affects the cost of TR19 inspection

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • The number of sites or systems
  • Working hours and out-of-hours timing
  • Where the site is and how we reach it
  • Site requirements such as sign-in and permits

What you pay depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.

What to send for a quote

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

  • Problems your staff have spotted
  • The times we could work without disrupting the site
  • The paperwork from the last visit, if you have it
  • How we’d reach plant on a roof or in a plant room
