How we price TR19 inspection
Your quote is based on your site. We take into account:
- Site requirements such as sign-in and permits
- Travel, parking and unloading
- The condition of the system
- How easy every part is to reach
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before any work starts.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles
- Wide photos of the system and the area around it
- Any symptoms, from odd noises to smells or leaks

How we handle TR19 inspection in Ashton
Many insurers ask for proof that kitchen extract systems are cleaned and inspected to TR19®. Missing records can lead to a claim being reduced or refused. A TR19 audit sets out the system’s condition, with readings and pictures, for sites in Ashton and the rest of Hampshire. The work covers wet film thickness tests, deposit thickness tests and post-clean checks, and people most often call us about post-clean verification after another contractor’s clean and cleaning intervals that may not suit the kitchen.
Somewhere as small as Ashton, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Common problems we fix in Ashton
Records can go missing when a business changes hands or contractors. Without them, nobody knows how much grease is in the system or when it was last cleaned.
These are the problems we see most often:
- Extracts that may be over the 200 micron mean
- Sections of duct that can’t be reached
- Kitchens taken over with no cleaning records
- Uncertainty over how often to clean
Bursars and site managers at schools such as Bishops Waltham Infant School tend to book extract cleaning for when the kitchen is empty.
What to look for in a quote
- When the next visit should be, and why
- Whether a survey comes first
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Proof of insurance
Leave it or put it right?
Sites in Ashton that have never measured grease can’t tell whether their cleaning interval suits the kitchen. Testing gives you the evidence to set it properly. Equipment tucked in a roof space or outbuilding near Ashton rarely gets looked at unless someone books it.
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 unsure, ring 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.

The process
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, which takes a couple of hours for a typical kitchen extract system. Photos of the system and how to reach it help us plan a visit to Ashton.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Agree a time when the area can be out of use
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards

TR19 inspection around Ashton
The Food Standards Agency lists about 5 bars, pubs and nightclubs as registered food businesses across Ashton and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. In Ashton, food businesses are inspected by environmental health officers from Winchester City council. 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. Hampshire and Isle of Wight Fire and Rescue Service covers Ashton. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
A hall kitchen that only cooks for events, whether near Church of St Peter or elsewhere in Ashton, still needs its extract cleaned, just less often. If you run catering at a healthcare site, such as a hospital like Moorgreen Hospital about 5.3 miles south-west, the extract may need cleaning more often than a part-time kitchen.

What TR19 inspection cannot fix
An honest diagnosis matters more to us than a booking, so here’s what TR19 inspection will not do:
- Sections with no access, until panels are fitted
- Fire safety duties beyond the extract system
- Heavy deposits found on test, which still need cleaning
If in doubt, phone us on 0345 646 2711 or use the quote form and we will say what we think.
Where we work
- Wet film thickness tests
- Access surveys
- Post-clean checks
- Pre-clean surveys
- Deposit thickness tests
- Insurer audits
How the job changes from site to site
Restaurants, pubs and hotels
A kitchen running from breakfast to late service builds grease quickly. Regular testing shows whether the cleaning interval keeps up.
Vertical risers
In buildings with several floors, the riser may pass through other tenants’ space, so we arrange access ahead of time.
Questions from Ashton
Do you work at weekends in Ashton?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Ashton needn’t be disturbed. Let us know the hours you’re closed and we will book within them.
Will you come out to Ashton?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
What does TR19 inspection cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
How far ahead should we book?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
How much time does an inspection need?
As a guide, it takes a couple of hours for a typical kitchen extract system. System size and access decide the rest.
What grease levels does TR19 allow?
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 if parts of the system cannot be reached?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
What happens to the waste?
We take it away at the end of the visit. While we work, it’s kept contained to keep the area clean.
Aftercare tips
So the system stays in good health:
- Never cook with filters missing
- Keep canopy edges and gutters wiped down
- Mention new equipment or longer hours at the next test
- Keep to the recommended interval
Where sections couldn’t be reached, the report says where access panels would help. With panels fitted, the next clean can cover every section.
Revisit the cleaning interval whenever the menu or hours change. Fresh readings show whether it needs to change.
