About our TR19 inspection in Clay Hill
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. Common call-outs are for an insurer’s request for a TR19 audit and sections of duct that can’t be reached, across insurer audits, wet film thickness tests and deposit thickness tests.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. In Clay Hill, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Fixed quotes for TR19 inspection in Clay Hill
The diagnosis comes before the price. We look at:
- Parking and loading at the site
- The times the site is available
- How easy every part is to reach
- The condition we find in the survey
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.
What we need to know
We can often survey from pictures. The most useful are:
- Any previous report or certificate
- Where the site is and what kind of site it is
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
To get a fixed quote, phone us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
Clay Hill kitchens: local notes
Look up Clay Hill on the FSA’s food hygiene register and you will find about 33 restaurants, cafés and canteens and about 20 takeaways and sandwich shops within roughly a mile and a half of the centre of Clay Hill. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. London jobs typically start after the last service, with loading and roof access agreed with the building first. Environmental health officers from Enfield council inspect food businesses in Clay Hill. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Bursars and site managers at schools such as St John's CofE Primary School tend to book extract cleaning for when the kitchen is empty. Church and community hall kitchens, near Church of St John the Baptist or anywhere around Clay Hill, are easy to forget, but their extracts collect grease like any other.

More services for Clay Hill
Do you need TR19 inspection in Clay Hill?
Kitchens change: a new menu, longer hours or more frying can all add grease. The old cleaning schedule may not match the kitchen any more.
Any of these means the system needs a check-up:
- Ductwork where grease may be over the TR19 limits
- Missing access panels found on survey
- Cleaning intervals that may not suit the kitchen
- Post-clean verification after another contractor’s clean
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Clay Hill is St Michaels Hospital, about 0.7 miles south.
What to look for in a quote

What happens if it’s left?
If a kitchen in Clay Hill has been cleaned on the same calendar for years, there’s no way to know if that interval is right without measuring. Testing gives you the evidence to set it properly. For a site in Clay Hill, fitting the work in overnight now is far easier than closing at short notice later.
What you pay reflects the actual work. That is why we survey first, from photos or on site, and why the quote is fixed before we start.

What happens on the day
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes an hour or two for a single kitchen, longer for a large or complex system. Getting kit into a London building takes planning, so let us know where we can load and park in Clay Hill.
- Post-clean verification is booked once the clean is done.
- 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.
- We report the findings and flag any areas that need more work.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Tell us where we can park and unload
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.
Advice
Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
FAQs for Clay Hill
Does London parking affect a job in Clay Hill?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we will book into it.
Do you do school kitchen extract cleaning in Clay Hill in the summer holidays?
Yes, holiday work suits schools best. The FSA’s register shows about 29 schools and colleges with food registrations within roughly a mile and a half of Clay Hill. Just phone us on 0345 646 2711 or email us with your term dates and we’ll plan around them.
Do you carry out TR19 audits for insurers?
Yes, for kitchens across the South East and London. Share the insurer’s request so the report addresses it.
Is a quote from pictures possible?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we normally come back within one working day. Some sites still need a visit, and we’ll say so.
Can you work evenings and weekends?
Yes. Evenings, nights and weekends are normal working hours for us, so you do not have to close during trading.
Can you verify a clean after it’s been done?
Verification means repeat readings and photos once the clean is done. Any areas that weren’t cleaned properly are flagged.
How do you measure grease in a kitchen extract?
We measure the grease at set points with a WFTT or DTT test, then compare them with the TR19® Grease figures.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
What TR19 inspection cannot fix
We will always give you a straight diagnosis, so here’s what TR19 inspection will not do:
- The legal duty, which stays with the responsible person
- Sections with no access, until panels are fitted
- Fan breakdowns, which need a repair visit
If you’re not sure, just call 0345 646 2711 or use the quote form and we will give you a straight answer.

What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
