TR19 inspection in Portswood
Not every kitchen fits neatly into a calendar. Some kitchens build up grease faster than the minimum intervals assume, and only measurement shows it. Our readings give your risk assessment real numbers to work from. The work covers deposit thickness tests, insurer audits and post-clean checks, and people most often call us about checking the result of a recent clean and kitchens taken over with no cleaning records.
For a smaller kitchen near Portswood, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Portswood kitchens: local notes
Portswood is within about 2 miles of the coast. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. According to Food Standards Agency records, there are about 74 bars, pubs and nightclubs and about 15 hotels and B&Bs within 1.5 miles or so of the middle of Portswood. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Environmental health officers from Southampton council inspect food businesses in Portswood. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready.
A kitchen near St Denys station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Royal South Hants Hospital is the nearest hospital to Portswood, about 0.9 miles south.
Portswood is about 1 mile north of Southampton, in Southampton. Portswood gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with photos. Portswood is one of 40 places in Southampton where we work for commercial clients.

FAQs for Portswood
Can sea air affect TR19 inspection in Portswood?
It can, as Portswood is within about 2 miles of the sea, where salt in the air is hard on metal. A fan housing that’s rusting near the coast can fail sooner, so it’s worth catching early.
Who carries out food hygiene inspections in Portswood?
In Portswood, it’s Southampton council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
At what point does grease need cleaning?
The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. We show your readings against those figures.
What is grease thickness testing?
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). Each reading is recorded in microns.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
What information do you need?
A short description and a few pictures, with the address and opening hours. If we need more, we’ll ask.
What happens on a pre-clean survey?
It’s a look at the whole extract before it’s cleaned, with readings and photos. The survey can be done from pictures and details or on site, whichever suits the system.
Why it’s worth doing now in Portswood
A check after cleaning shows whether the work reached every part it should have, while there’s still time to put anything right. Booking ahead lets us plan the trip to Portswood at a time that suits you.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

Part by part
Schools, hospitals and care homes
We fit testing around service times and school holidays so meals aren’t affected.
Horizontal duct runs
Bends and long runs can hold heavy deposits, well away from where anyone looks.
What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Between visits
So the system stays in good health:
- Book the next test on the date in the report
- Share inspection reports with your insurer or broker when asked
- Clean or swap grease filters as often as the kitchen needs
- Mention new equipment or longer hours at the next test
The audit report is set out to pass straight to your insurer or broker, including readings, photos and any inaccessible sections.
When cooking hours or the menu change, check the interval still fits. A quick grease test answers the question.
The process
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes a couple of hours for a typical kitchen extract system. In a smaller place like Portswood, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Arrange a key holder or contact on site
- Make sure equipment near the work can be switched off and left to cool
- Let us know about parking and loading
Getting a quote
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

What we’re called out for in Portswood
Some parts of a system are hard to reach, and grease can be missed there clean after clean. A survey finds the sections that can’t be reached, so panels can be fitted.
It’s time to book a visit if you see:
- Confirming a clean reached the whole system
- Insurance renewals needing proof of TR19 cleaning
- Missing access panels found on survey
- Extracts that have never been grease tested
Bursars and site managers at schools such as St Denys Primary School tend to book extract cleaning for when the kitchen is empty.
