Mill Hill: your questions answered
Is parking a problem for work in Mill Hill?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Night visits tend to make loading easier on London streets.
Who enforces fire safety at workplaces in Mill Hill?
London Fire Brigade is the fire and rescue service for Mill Hill. 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.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
How much notice should we give?
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.
Do we have to follow TR19 by law?
No. TR19® is a specification, not a statute. In practice, an insurer can refuse or reduce a claim without proof of TR19 cleaning, so it matters in practice.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
What does TR19 inspection cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, typically ready within one working day.
What happens on a pre-clean survey?
A survey finds out how the system is laid out, how dirty it is and what can be reached, so the clean goes to plan. Any access problems are flagged so they can be sorted first.
TR19 inspection in Mill Hill, done properly
If you’ve taken over a kitchen in Mill Hill and don’t know when the extract was last cleaned, an inspection is the place to start. You get readings, photos and a clear view of what’s needed, before any cleaning is booked. The work covers wet film thickness tests, access surveys and pre-clean surveys, and the jobs we see most are an insurer’s request for a TR19 audit and kitchens taken over with no cleaning records.
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. For a kitchen in Mill Hill, that typically means a longer system to clean and more access panels to plan around.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Fixed quotes for TR19 inspection in Mill Hill
A fixed price needs a few facts first. We check:
- The number of sites or systems
- Travel, parking and unloading
- The size of the system
- Access, including roofs, risers and ceiling voids
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What to send for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Any previous report or certificate
- The site address and the type of premises
- Detail shots of panels, filters and grilles
- Problems your staff have spotted
If you need TR19 inspection in Mill Hill, ring 0345 646 2711 or drop us a line. Let us know the site type and the opening hours, and send photos or your last report if you can. A fixed quote usually follows within one working day.
Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Keeping the system healthy
To keep the system working properly between visits:
- Look out for grease drips round the canopy edge
- Clean or swap grease filters as often as the kitchen needs
- Diary the next grease test and clean
- Keep access panels clear and unpainted
Each report suggests the next clean and the next test, from the measured grease and the kitchen’s hours.
Revisit the cleaning interval whenever the menu or hours change. Fresh readings show whether it needs to change.
How it works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Before any visit in Mill Hill, we agree where the van can stop and how equipment reaches the system.
- We go through any past certificates and reports.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Mention any sign-in, permit or induction we need
- Mention any parking or loading restrictions
Getting a quote
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711, or send details by email.

TR19 inspection in Mill Hill: the local picture
The FSA’s data shows about 19 pubs, bars and clubs registered within 1.5 miles or so of the middle of Mill Hill. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. London Fire Brigade covers Mill Hill. 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. In London, kitchens are usually cleaned overnight, when the kitchen is closed and loading is easier.
A hall kitchen that only cooks for events, whether near St Paul's Church or elsewhere in Mill Hill, still needs its extract cleaned, just less often. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Edgware Community Hospital is the nearest hospital to Mill Hill, about 2 miles south-west. Historic houses near Mill Hill, such as Heath Hall about 4 miles south-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

What happens if it’s left?
Skipping grease testing leaves the cleaning interval to guesswork. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, and you can only act on that if you’ve measured it. Choosing the date yourself beats having a fault choose it for you.

Honest limits
Some problems need a different service or another trade:
