TR19 inspection in Five Oaks
A fixed schedule does not always match how a kitchen really cooks. 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. Common call-outs are for surveys needed before quoting a full clean and extracts that have never been grease tested, on post-clean checks, wet film thickness tests and insurer audits.
In a small place like Five Oaks, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Grease, kitchens and Five Oaks
Five Oaks, about 35 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours. Five Oaks sits within the area of 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.
A hospital like Horsham Hospital, about 5 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Bursars and site managers at schools such as The Weald School tend to book extract cleaning for when the kitchen is empty.

What a clean will not put right
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Installation problems, which fall under design guidance such as DW172

- Parts of the duct nobody can reach yet

Fixed quotes for TR19 inspection in Five Oaks
Your quote is based on your site. We take into account:
- A single visit or a regular plan
- How easy every part is to reach
- Working hours and out-of-hours timing
- What state the system is in
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, call 0345 646 2711 or send us an email for straight advice and a fixed quote.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Any previous report or certificate
- The postcode and the type of business
- When the site is open and when it’s quiet
- Close-ups of filters, grilles, hatches or access panels
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
How the job changes from site to site
Vertical risers
Access to risers is often limited. The survey shows exactly what access there is.
Horizontal duct runs
Grease can gather thickly at bends and along long runs, out of sight of the kitchen.
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Keep canopy edges and gutters wiped down
- Keep the route to access panels clear
- Report grease dripping from the canopy
- Mention new equipment or longer hours at the next test
Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can arrange it.
Regular grease readings keep the cleaning interval honest. It shows if build-up is speeding up.
What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.

Which fire service covers Five Oaks?

It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Can the work be done while we are closed?
Yes. Evenings, nights and weekends are normal working hours for us, so the site doesn’t lose a service.
When should we have our next grease test?
We suggest a next test date in every report, based on the readings and how the kitchen is used. The interval should come from a competent person’s risk assessment backed by grease measurement.
How much does TR19 inspection cost in Five Oaks?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before we start.
What is a WFTT or DTT grease test?
Grease thickness testing measures the layer of grease on the duct surfaces, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). The results are given in microns.
