TR19 inspection near Northam

How the visit works

Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Your opening hours decide when we come to Northam, not ours.

  1. The visit is arranged for when the kitchen is not busy.
  2. The system is checked from canopy to 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. The findings go into a report with readings, photos and a recommended next clean.

Getting ready for the visit

  • Name a contact who can let us in at the agreed time
  • Move anything stored near the system
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Getting a quote

For a fixed quote, ring 0345 646 2711 or email us 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 usually come back within one working day.

About our TR19 inspection in Northam

Post-clean verification is a check carried out once the cleaning is done, with fresh grease readings, pictures and a look at the areas that were cleaned. It shows whether the system was left in the condition the paperwork describes. If you’re dealing with parts of the system left out of past cleans and ductwork where grease may be over the TR19 limits, we can help.

Kitchens around a place like Northam are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.

Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What affects the quote in Northam

Before we fix a price, we need to know a few things. We look at:

  • The size of the system
  • The number of sites or systems
  • The times the site is available
  • One-off work versus a regular cycle

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.

What to send for a quote

There’s no need for technical detail. Just send:

  • Photos showing the whole system and its surroundings
  • The site address and the type of premises
  • The times we could work without disrupting the site
  • Close-ups of filters, grilles, hatches or access panels

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

Multi-site and managed buildings

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.

Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.

What TR19 inspection looks like in Northam

Northam is within about 2 miles of the coast. Near the sea, the fan and discharge at the top of a kitchen extract corrode faster than they would inland. Food Standards Agency records list about 310 restaurants, cafés and canteens and about 109 sandwich bars and takeaways across Northam and its immediate surroundings (about a mile and a half). Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. In Northam, food businesses are inspected by environmental health officers from Southampton council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.

If you look after a school kitchen, at a school such as Bitterne Manor Primary School or anywhere near Northam, the holidays are the usual time for a TR19® clean. If you run catering at a healthcare site, such as a hospital like Royal South Hants Hospital about 0.8 miles west, the extract may need cleaning more often than a part-time kitchen.

Northam is about 1 mile south-east of Southampton, in Southampton. Northam gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with pictures. Across Southampton, we cover 40 places, Northam among them.

Work in SO14, SO19 and SO18 is surveyed, quoted and booked the same way as anywhere else. TR19 inspection is available to premises on Sea Road, Lumpy Lane and Cross Road and the roads around them. Close by, we work in Peartree Green (1 mile south), Bitterne Manor (1 mile north), Itchen (1 mile south-east), St Mary's (1 mile south-west) and Bitterne (1 mile east). Within a short drive, we also cover Regents Park (3 miles west), Maybush (3 miles north-west), Coxford (3 miles north-west), Lordswood (3 miles north-west), Eling (5 miles west) and Rownhams (4 miles north-west).

When something else is needed

An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:

  • A faulty or failing extract fan
  • The responsible person’s own fire risk assessment
  • Design faults in the extract system

Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we will tell you honestly.

What the work covers

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

Different parts, different methods

Extract fan and discharge

A greasy fan works harder and wears faster. Readings show if it needs attention before the next clean.

Schools, hospitals and care homes

In healthcare and care settings, kitchens may run from early until late. Testing shows if the cleaning interval keeps pace.

Common problems we fix in Northam

Menus, opening hours and cooking styles change over time, and more frying or longer hours mean more grease. A cleaning interval set years ago may no longer fit.

Any of these means the system needs a check-up:

  • Surveys needed before quoting a full clean
  • Missing access panels found on survey
  • Insurance renewals needing proof of TR19 cleaning
  • Kitchens whose menu or hours have changed

A hall kitchen that only cooks for events, whether near Church of St Augustine or elsewhere in Northam, still needs its extract cleaned, just less often.

What your quote should include

  • Whether VAT is included
  • What paperwork you get at the end
  • Whether the work can be done while the site is closed
  • If they look at the system before pricing

How to choose an extract cleaning contractor

FAQs for Northam

Do you work in villages like Northam?

Yes, we work in villages as well as towns, and Northam is covered. Photos of the system and directions to the site help us plan the visit.

Who enforces fire safety at workplaces in Northam?

That is Hampshire and Isle of Wight Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.

What is a WFTT or DTT grease test?

It’s a measurement of how much grease is coating the inside of the extract, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). The results are given in microns.

Can you price the work without visiting?

Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, then a fixed quote.

What do you do to protect the area?

Floors and surfaces near the work are sheeted before any work starts, and waste is contained as we go. At the end, the area is cleaned down.

How long does grease testing take?

An inspection takes a couple of hours for a typical kitchen extract system. Sites with several canopies take longer, and you can give us a ring on 0345 646 2711 or send us an email to book it in.

Do you work with multi-site operators?

Yes. Send the list of sites and the work at each and you’ll get one fixed quote.

What is post-clean verification?

We visit after a clean, take readings at set points and photograph the system. Any areas that weren’t cleaned properly are flagged.

Leave it or put it right?

Without readings, you are guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, which you will not know without measuring. Booking ahead lets us plan the trip to Northam at a time that suits you.

Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
