TR19 inspection for sites in Thorney Island

Why it’s worth doing now in Thorney Island

Catching heavy deposits early keeps the fix small. Ignored, the layer only gets thicker. If the system at a site near Thorney Island fails, there may be nowhere nearby to move to.

Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call us on 0345 646 2711, or send details by email for straight advice and a fixed quote.

How we handle TR19 inspection in Thorney Island

After a clean, post-clean verification checks the result, with fresh grease readings, photos and a look at the areas that were cleaned. It shows whether the system was left in the condition the paperwork describes. If you have systems that need surveying before cleaning and insurers asking for TR19 evidence, we can help.

In a village or hamlet like Thorney Island, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease.

Good records are part of the job. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Staff cleaning versus specialist work

In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.

Thorney Island kitchens: local notes

At about 1 mile from the coast, Thorney Island is close enough for sea air to matter. Metal on the roof weathers faster close to the coast, and the extract fan and cowl are no exception. Food Standards Agency data counts about 6 restaurants, cafés and canteens in and around Thorney Island, up to about a mile and a half out. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. The fire and rescue service for Thorney Island is West Sussex 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.

Where a hall near The Parish Church of St Nicholas, or anywhere in Thorney Island, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If your kitchen is in a listed or historic building, like the houses around Thorney Island (Warblington Castle is about 2.1 miles north-west), fitting access panels needs care.

How we price TR19 inspection

Every site gets its own quote. These are the things that affect it:

  • When the work can happen, such as evenings, overnight or weekends
  • The number of sites or systems
  • How easy every part is to reach
  • Where the site is and how we reach it

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.

Helping us quote

The more you tell us, the more accurate the quote. When you get in touch, it helps to send:

  • Detail shots of panels, filters and grilles
  • Wide pictures of the system and the area around it
  • Your last certificate, test record or report
  • When the site is open and when it’s quiet

Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before we start.

How it works

The visit has three parts: 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. The middle part takes longest, which takes a couple of hours for a typical kitchen extract system. If you can send photos, we can arrive in Thorney Island knowing what to expect.

  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. We photograph the test points and record any sections we cannot reach.
  5. We send a report setting out the readings, pictures and next steps.

Before we arrive

  • Tell us the best time to work, such as after service or at a weekend
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Allow time for equipment near the work to be turned off and cool down

Landlords, agents and facilities managers

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

Facilities teams in offices, schools and healthcare sites book us too in Thorney Island and across West Sussex. Larger estates can be phased building by building around the people who use them.

Thorney Island questions

Do you work in villages like Thorney Island?

Yes, we work in villages as well as towns, and Thorney Island is covered. Let us know about access, parking and anything unusual about getting there when you book.

Who is the fire and rescue service for Thorney Island?

It’s West Sussex Fire and Rescue Service, which covers Thorney Island. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.

What happens on a pre-clean survey?

It’s a look at the whole extract before it’s cleaned, with readings and pictures. The survey can be done from pictures and details or on site, as suits the job.

Where does the waste go?

Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.

Do you offer emergency callouts?

Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.

Are you accredited?

Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

When should we have our next grease test?

Often enough to know the mean stays under 200 microns between cleans. The readings themselves tell you if the interval needs to change.

Do we have to follow TR19 by law?

No, not in itself. The Fire Safety Order 2005 still requires the responsible person to manage fire risk, and grease in the extract is part of that. Many insurance policies also require TR19 adherence.

Do you need TR19 inspection in Thorney Island?

Insurers, fire officers and environmental health officers look to TR19® as the benchmark. It isn’t legislation; the legal duty comes from the Fire Safety Order 2005, under which the responsible person must reduce fire risk, and grease in the extract is part of that risk.

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

  • An insurer’s request for a TR19 audit
  • Kitchens taken over with no cleaning records
  • Systems cleaned on a calendar with no measurements
  • Kitchens whose menu or hours have changed

School kitchens, at schools like Thorney Island Community Primary School for example, are usually cleaned in the holidays so no lunches are lost.

What to look for in a quote

  • Whether a survey comes first
  • Proof of insurance
  • Whether the work can be done while the site is closed
  • When the next visit should be, and why
