Fixed quotes for TR19 inspection in Brook
The price is fixed before any work begins. It’s based on:
- When the work can happen, such as evenings, overnight or weekends
- The number of sites or systems
- Site rules, permits and inductions
- The condition we find in the survey
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Your last certificate, test record or report
- A few general shots of the system
- Where the site is and what kind of site it is
- Problems your staff have spotted
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before work begins.
How we handle TR19 inspection in Brook
A grease test measures how thick the grease is inside a kitchen extract system. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. The results show whether the system needs cleaning and how soon. If you have sites with gaps in their extract records and post-clean verification after another contractor’s clean, we can put it right.
Somewhere as small as Brook, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How it works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Somewhere as small as Brook, the date and timings are agreed with you well before the day.
- The visit is arranged for when the kitchen is not busy.
- The system is checked from canopy to discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- We photograph the test points and record any sections we cannot reach.
- You get a report with readings, photos and recommendations.
Before we arrive
- Let us know when the site is closed or quiet
- Move anything stored near the system
- Let us know about permits to work or site inductions
How to get a quote
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.

For landlords and multi-site operators
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.
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Have the latest report ready for insurance renewals
- Keep the route to access panels clear
- Keep grease filters clean and fitted properly
- File every inspection report with your certificates
You get a report with the grease readings, where they were taken and photos of each point. File it alongside your TR19 certificates.
Test grease regularly instead of relying on the calendar. It shows if build-up is speeding up.
In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
How the job changes from site to site
Schools, hospitals and care homes
We fit testing around service times and school holidays so meals aren’t affected.
Extract fan and discharge
The extract fan and its housing collect grease too. We check and test them as part of the inspection.
Kitchen extracts in Brook
Brook, about 35 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours. Fire safety in Brook falls to Surrey Fire and Rescue Service. 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.
If you look after a school kitchen, at a school such as King Edward's School Witley or anywhere near Brook, the holidays are the usual time for a TR19® clean. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Brook is Milford Hospital, about 3 miles north-east.
Brook is about 8 miles south-east of Farnham, in Surrey. Whatever kind of site you run in Brook, TR19 inspection is something we can help with.

Around Brook

Why deal with it now?
Without readings, you’re guessing when to clean. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, which you won’t know without measuring. Rural sites cannot always move to another kitchen or room when something fails.
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 are not sure what’s needed, call us on 0345 646 2711, or send details by email for straight advice and a fixed quote.

Common questions in Brook
Which fire authority looks after Brook?
That is Surrey Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Which council inspects kitchens in Brook?
Kitchens in Brook are inspected by Waverley council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
What grease levels does TR19 allow?
Two figures matter: a mean of no more than 200 microns between cleans, and 500 microns at any single point, which needs immediate spot cleaning. Our report sets your readings against both.
Will you produce a report for our insurer?
Yes. Insurers often want evidence the extract is managed to TR19®, and our audit gives a clear record of the system’s condition, with recommendations where something needs doing.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
When should we have our next grease test?
It depends on how heavily the kitchen cooks. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and testing shows if your kitchen needs more.
What is grease thickness testing?
Grease thickness testing measures the layer of grease on the duct surfaces, by WFTT or DTT. The results are given in microns.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
