Leave it or put it right?
Without readings, you are guessing when to clean. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, which you will not know without measuring. In a small place like Blackbrook, a system that fails can take a site out of use.
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or email us, and we’ll explain what it covers.

How we handle TR19 inspection in Blackbrook
Taking on a kitchen in Blackbrook with no cleaning records? Start with an inspection. We survey the system, measure the grease and tell you what needs doing, so the next step is based on facts. We’re often asked to deal with extracts that have never been grease tested and kitchens taken over with no cleaning records, on deposit thickness tests, post-clean checks and pre-clean surveys.
In a village or hamlet like Blackbrook, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Different parts, different methods
Extract fan and discharge
The discharge at the end of the system is checked as well, since grease reaches the very end of the system.
Horizontal duct runs
Flat duct runs collect grease along their base. Readings are taken along each run through its access panels.
Common questions in Blackbrook
Do you work overnight in Blackbrook?
Yes. We work evenings, overnight and at weekends. It means the site in Blackbrook keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Can you get to a site in Blackbrook?
Yes, we work in villages as well as towns, and Blackbrook is covered. The journey is planned ahead, so a few details about the route help.
When should we have our next grease test?
That varies with the kitchen’s daily use. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and grease readings help set the real interval.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What happens on a pre-clean survey?
We look at the system from canopy to discharge, take grease readings and check access. It lets us plan the clean and send you a fixed quote.
How much time does an inspection need?
As a guide, it takes a morning or less for one kitchen, more where there are several systems. The size of the system and the access make the difference.
Is there a survey before the work?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. Then you get a fixed quote.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
Kitchen extracts in Blackbrook
Look up Blackbrook on the FSA’s food hygiene register and you will find about 6 restaurants, cafés and works canteens within about 1.5 miles of central Blackbrook. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Blackbrook sits within the area of Surrey Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Food hygiene inspections in Blackbrook are the job of Mole Valley council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.
Term dates shape school work: for a school like St John's Church of England Primary School, an extract clean fits neatly into a half-term or summer break. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Polesden Lacey is about 4.3 miles north-west), access may need planning. If you run a church or community hall kitchen, near Church of St John the Evangelist or elsewhere in Blackbrook, its extract still collects grease from every lunch and event.

What affects the quote in Blackbrook
Your quote is based on your site. We consider:
- The condition we find in the survey
- How big the system is
- Where the site is and how we reach it
- Site requirements such as sign-in and permits
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before we start.
Helping us quote
You do not need the technical terms. It helps if you can send:
- Where the site is and what kind of site it is
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles
- Photos showing the whole system and its surroundings
If you need TR19 inspection in Blackbrook, ring 0345 646 2711, or email photos. Tell us what kind of premises it is and when it’s open, plus photos or the previous report if they’re to hand. We usually send a fixed quote within one working day.

Looking after it afterwards
So the system stays in good health:
- Keep canopy edges and gutters wiped down
- Keep the route to access panels clear
- Tell us if menus or opening hours change
- Store grease readings where your insurer can see them
For an insurer audit, send them the report as it is, with readings, photos and any areas not accessible.
Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.
Honest limits
It’s worth knowing the limits before booking:
- A faulty or failing extract fan
- Sections with no access, until panels are fitted
- Removing the grease, which is a separate clean
If in doubt, phone us on 0345 646 2711 or send us an email and we will say what we think before booking.
Where we work

What we do, step by step
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes a morning or less for one kitchen, more where there are several systems. Rural roads and tight entrances are worth telling us about before a visit to Blackbrook.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- Grease readings are taken and photos recorded.
- We report back with readings and a fixed quote.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know when the site is closed or quiet
- Clear the space around the work
Getting a quote
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. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
