TR19 kitchen extract cleaning in Underhill
The ducts are where most of the grease hides. We reach horizontal runs and vertical risers through access panels, removing thick grease by hand, then using degreasers, hot water or steam to suit the deposit. Anything out of reach is noted in the report, and new panels can be fitted. Typical jobs include a TR19 certificate needed for the insurer and poor airflow at the canopy, on plenums and filters, extract fans and canopies and hoods. When a restaurant in Underhill asks for duct cleaning, it’s nearly always the kitchen extract they mean, and that’s exactly what we do: canopy to fan, to TR19® Grease.
Each job starts with a look at where grease has built up: grease readings at set points tell us where the heaviest deposits are, and readings afterwards go into your report.
In London, few kitchens can spare a day to close, so extract cleaning in Underhill is normally done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Why deal with it now?
After a fire, one of the first questions is often when the extract was last cleaned. Many insurers ask for proof of TR19 cleaning and may reduce or refuse a claim without it. A certificate in the file answers that question. Leaving it on a busy London site only adds to the work.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before any work starts.

How the job changes from site to site
Restaurant and pub kitchens
High-heat cooking loads the extract with grease, so grease readings help set the right interval.
Grease filters
Between TR19 cleans, filters still need regular cleaning, and a filter exchange service can take that off your hands. Keeping them clean helps the rest of the system stay cleaner.

Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Give the canopy a daily wipe
- Keep to the recommended cleaning interval
- Do not let the canopy gutters overflow
- Keep the cleaning records where you can find them
Every clean ends with a photo report. It shows the system before and after, part by part, alongside a list of what was cleaned, anything out of reach and the recommended next clean date.
Clean the grease filters often, not just on clean day. Clean, well-fitted filters catch more fat before it reaches the duct, so the ductwork stays cleaner for longer.
What your team can do, and what needs us
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
What affects the quote in Underhill
We do not publish a price list, because sites vary so much. What we look at:
- Parking and loading at the site
- One-off work versus a regular cycle
- Site rules, permits and inductions
- The condition we find in the survey
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles
- A few general shots of the system
To get a fixed quote, ring 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.
Do you need kitchen extract cleaning in Underhill?
A kitchen in Underhill builds up grease in the same places as any other: long horizontal runs, bends, the base of risers and around the fan. The cooler the duct, the more grease drops out of the air.
What we’re most often called out for:
- Rancid smells from grease in the duct
- A new tenancy or takeover with no cleaning history
- An extract that has never been cleaned to TR19
- Fat running down the canopy edge
Term dates shape school work: for a school like St Catherine's RC School, an extract clean fits neatly into a half-term or summer break.
What your quote should include
- Whether VAT is included
- Proof of insurance
- Whether a written report and pictures are included
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
FAQs for Underhill
Who is the fire and rescue service for Underhill?
Fire safety enforcement in Underhill is handled by London Fire Brigade. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Do you clean school canteen extracts around Underhill out of term?
Yes, holiday work suits schools best. With about 30 schools and colleges on the FSA’s register within roughly a mile and a half of Underhill, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Is Underhill in your area?
Yes. We cover Underhill and across Greater London, within our South East and London area. For a fixed quote, call us on 0345 646 2711 or email us.
Do I have to clean my extract to TR19 by law?
No law names TR19 directly, but the responsible person still has a legal duty under the Fire Safety Order 2005. Insurers, fire officers and EHOs look to TR19 as the standard, and many policies require it.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We don’t leave it behind.
Grease, kitchens and Underhill
The FSA’s data shows about 30 pubs, bars and clubs registered across Underhill and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Underhill is covered by London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Food hygiene inspections in Underhill are the job of Barnet council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
A hospital like Barnet General Hospital, about 0.9 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If your kitchen is in a listed or historic building, like the houses around Underhill (Wyllyotts Manor is about 3.4 miles north), fitting access panels needs care.
