TR19 inspection for kitchens and businesses in Bush Hill
Taking on a kitchen in Bush Hill 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. The work covers wet film thickness tests, pre-clean surveys and post-clean checks, and the jobs we see most are kitchens taken over with no cleaning records and uncertainty over how often to clean.
London kitchens tend to trade late and open early, so work in Bush Hill is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
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, and we have been trading since 2009.

What else we do in Bush Hill
What the work involves, part by part
Extract fan and discharge
Grease on the fan adds to wear. Readings show if it needs attention before the next clean.
Horizontal duct runs
Flat duct runs collect grease along their base. Readings are taken along each run through its access panels.
Fixed quotes for TR19 inspection in Bush Hill
You’ll get a fixed price before we start. It takes into account:
- The scale of the work
- The condition of the system
- Site rules, permits and inductions
- How easy every part is to reach
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Helping us quote
Before you ask for a quote, gather:
- Any previous report or certificate
- A few general shots of the system
- Any access panels or hatches you can see
- Any symptoms, from odd noises to smells or leaks
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
What we are called out for in Bush Hill
Grease builds up as cooking vapour cools inside the extract. It often collects where nobody can see it: the plenum, bends and horizontal runs.
Common reasons sites call us include:
- Surveys needed before quoting a full clean
- Missing TR19 certificates or history
- Parts of the system left out of past cleans
- Kitchens whose menu or hours have changed
Church and community hall kitchens, near Grange Park Methodist Church or anywhere around Bush Hill, are easy to forget, but their extracts collect grease like any other.
What to look for in a quote
- What insurance they carry
- If the quote is a fixed price or an estimate
- Proof of accreditation you can verify
- Whether a survey comes first
Bush Hill: your questions answered
Who inspects food businesses in Bush Hill?
That is Enfield council, whose environmental health officers carry out food hygiene inspections in Bush Hill. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can parking be tricky for a job in Bush Hill?
London parking can be tight, so details of loading bays and permits help. Working overnight, as we often do in London, typically makes it simpler.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before work begins, and anything we remove is contained. At the end, the area is cleaned down.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Can the work be done while we’re closed?
Yes. Much of our work happens in the evening, overnight or at weekends, so you do not have to close during trading.
What is post-clean verification?
Post-clean verification is a check after a clean, with fresh grease readings and pictures. It works whoever carried out the clean.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.
At what point does grease need cleaning?
The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. Our report sets your readings against both.
Bush Hill kitchens: local notes
Food Standards Agency data counts about 168 restaurants, cafés and canteens and about 79 takeaways across Bush Hill and its immediate surroundings (about a mile and a half). Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Kitchens in Bush Hill get their food hygiene inspections from Enfield council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Most London extract cleaning happens at night, after the last service.
If you look after a school kitchen, at a school such as Grange Park Preparatory School or anywhere near Bush Hill, the holidays are the usual time for a TR19® clean. Healthcare kitchens, like those at hospitals such as St Michaels Hospital (about 1.4 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands.
Bush Hill is about 1 mile south of Enfield, in Greater London.

Between visits
Here’s the after-treatment advice, short and simple:
- Report grease dripping from the canopy
- Share inspection reports with your insurer or broker when asked
- Don’t box in or cover duct access panels
- Keep grease filters clean and fitted properly
The audit report is set out to pass straight to your insurer or broker, including readings, pictures and any inaccessible sections.
Keep all TR19 records together so you can produce them quickly.
Managing agents and facilities teams in Bush Hill
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
