Managing agents and facilities teams in Blacknest
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
How we handle TR19 inspection in Blacknest
BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Grease testing shows whether your kitchen needs cleaning more often than that. Common call-outs are for ductwork where grease may be over the TR19 limits and an insurer’s request for a TR19 audit, across deposit thickness tests, insurer audits and post-clean checks.
Work in a small place like Blacknest starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

TR19 inspection in Blacknest: the local picture
The FSA’s food hygiene register shows about 22 restaurants, cafés and works canteens across Blacknest and its immediate surroundings (about a mile and a half). Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. Kitchens in Blacknest get their food hygiene inspections from Windsor and Maidenhead council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Fire safety in Blacknest falls to Royal Berkshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
School kitchens, at schools like Holy Trinity CofE Primary School for example, are typically cleaned in the holidays so no lunches are lost. If you run catering at a historic house or estate in the area (St Leonard's Hill is about 4.2 miles north), event kitchens in older buildings often have awkward duct runs that need planning.

What affects the quote in Blacknest
Before we fix a price, we need to know a few things. We look at:
- The times the site is available
- Whether it’s a one-off visit or part of a schedule
- The size of the system
- Site rules, permits and inductions
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, call us on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The roof, plant room or outside wall the system runs to
- A few general shots of the system
- The postcode and the type of business
We don’t publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, call 0345 646 2711, or email photos.
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Keep grease filters clean and fitted properly
- Diary the next grease test and clean
- Keep the route to access panels clear
- Wipe the canopy surfaces regularly
After the inspection, we send a report showing each reading, its location and pictures. File it alongside your TR19 certificates.
Fit access panels where the survey finds sections can’t be reached, so grease isn’t left building in hidden parts.
What we are called out for in Blacknest
TR19® is the benchmark that insurers, fire officers and EHOs refer to. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and grease in the extract is part of that risk.
Common reasons sites call us include:
- Ductwork where grease may be over the TR19 limits
- Kitchen extract systems with no recent grease readings
- Checking the result of a recent clean
- An insurer’s request for a TR19 audit
A hall kitchen that only cooks for events, whether near Holy Trinity Church or elsewhere in Blacknest, still needs its extract cleaned, just less often.
Before you book anyone
- Whether inaccessible sections are listed on the report
- If they look at the system before pricing
- Exactly which parts of the system are covered
- Whether the quote shows VAT
Part by part
Horizontal duct runs
Flat duct runs collect grease along their base. Readings are taken along each run through its access panels.
Vertical risers
Risers carry the extract up through the building. Grease can run down and collect at the base, so we check there.
How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a couple of hours for a typical kitchen extract system. We agree a date with you, plan the drive to Blacknest and turn up when the site is quiet.
- We agree a time when the kitchen is closed or quiet.
- We look over the canopy, plenum, ducts, fan and discharge.
- We take WFTT or DTT readings at set points along the system.
- Each test point and any access problems are photographed.
- The findings go into a report with readings, pictures and a recommended next clean.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Clear the space around the work
- Name a contact who can let us in at the agreed time
How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Advice
Your questions about TR19 inspection in Blacknest
Can you clean school kitchen extracts in Blacknest during the holidays?
Yes, holiday work suits schools best. The FSA’s register shows about 9 schools and colleges with food registrations within roughly a mile and a half of Blacknest. Tell us your holiday dates and we will book the visit for when the site is empty.
Which fire authority looks after Blacknest?
That is Royal Berkshire Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
Can you inspect our extract for our insurance company?
Yes, for kitchens across the South East and London. Share the insurer’s request so the report addresses it.
How much notice do you need?
The more notice, the better, especially for out-of-hours work. Quotes typically come back within one working day, and emergencies are covered by our 24/7 line.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
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 is post-clean verification?
We visit after a clean, take readings at set points and photograph the system. Any areas that weren’t cleaned properly are flagged.
When it’s something else
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Parts of the duct nobody can reach yet
- Removing the grease, which is a separate clean
- Fan breakdowns, which need a repair visit
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we will say what we think.
