Kitchen extraction cleaning in Walsworth
TR19 grease cleaning of complete kitchen extract systems, from canopy to discharge for Walsworth, with a survey first and a report with pictures at the end. Ask us for a fixed quote.
- Fat running down the canopy edge
- A TR19 certificate needed for the insurer
- An inspection that picked up a dirty extract
Different parts, different methods
Ductwork and risers
Horizontal runs collect grease as the air slows and cools. Each run is cleaned through its access panels, recording any that can’t be reached.
Canopy and plenum
Behind the grease filters sits the plenum, which daily cleaning never reaches. With the filters out, the plenum is scraped and degreased.
Kitchen extract cleaning in Walsworth, done properly
Not sure when the extract was last cleaned, or by whom? Just call us on 0345 646 2711 or email us with pictures of the canopy and filters, and we will come back with a fixed price for the work in Walsworth, typically within one working day. If you have a new tenancy or takeover with no cleaning history and grease dripping from the canopy or filters, we can put it right. Kitchens in Walsworth book us for TR19 cleaning for three reasons: the insurer asked, the EHO asked, or the canopy is dripping. We handle the clean and the paperwork in one visit.
Grease that collects out of sight, behind the filters and along the duct, is what insurers and fire officers worry about, which is why a TR19® clean in Walsworth goes well beyond the canopy.
For a smaller kitchen near Walsworth, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Kitchen extract cleaning in Walsworth: the local picture
The Food Standards Agency lists about 37 pubs, bars and clubs and about 5 hotels and B&Bs as registered food businesses within 1.5 miles or so of the middle of Walsworth. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Fire safety in Walsworth falls to Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. It’s North Hertfordshire council that sends environmental health officers to food businesses in Walsworth. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.
Where a hall near St Faith's Church, or anywhere in Walsworth, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you run a café or takeaway near Hitchin station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. School kitchens, at schools like Highover Junior Mixed and Infant School for example, are typically cleaned in the holidays so no lunches are lost.

How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a single shift for most kitchens, with long duct runs and tall risers needing more time. Getting to the system matters more than parking in a place like Walsworth, so let us know how to reach it.
- Diagnosis comes first, with a survey of the system and how it’s reached.
- We record grease levels at set points, then fix the price.
- We arrive after close, protect the area and contain the waste.
- Heavy deposits are scraped by hand and the system degreased to TR19® Grease.
- Then the clean bill of health: readings, a TR19 certificate and a photo report with the next date.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us about site rules, permits or sign-in
- Plan for cooking equipment or plant to be off before we arrive
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Advice
Walsworth: your questions answered
Who is the fire and rescue service for Walsworth?
Walsworth is in the area of Hertfordshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Who would carry out a food hygiene inspection at a kitchen in Walsworth?
That is North Hertfordshire council, whose environmental health officers carry out food hygiene inspections in Walsworth. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
What’s the right cleaning interval for a kitchen extract?
BESA guidance sets minimums by daily cooking hours: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Measured grease levels set the real interval.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Which parts of the extract do you clean?
All of it, from the canopy through to the discharge. Where there aren’t enough access panels to reach a section, it’s recorded, and we can fit new ones.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.

Why deal with it now?
TR19® is not law, but the Regulatory Reform (Fire Safety) Order 2005 is. The responsible person must assess and reduce fire risk, which in a kitchen includes the grease in the extract. Cleaning to TR19 is the recognised way to show you’ve done it. Even a site near Walsworth that’s only busy part of the week needs its system checked on a schedule.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.

Managing agents and facilities teams in Walsworth
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Between visits
Good habits slow the build-up between visits. A few tips:
- Keep the TR19 certificate and photo report in the maintenance log
- Run the extract fan throughout cooking
- Report grease drips, smells or fan noise straight away
- Keep the baffle filters clean
A TR19 certificate notes the date, the location and the technician. File it with the fire risk assessment and the maintenance log so it’s ready when anyone asks to see it.
Run the extract whenever the kitchen is cooking. Switching it off early leaves vapour to settle on the canopy and plenum, and the next clean has more to do.
What a clean will not put right
An honest diagnosis matters more to us than a booking, so here’s what kitchen extract cleaning will not do:
- Extraction that can’t cope with the cooking because of its design
- Ductwork that is corroded, split or leaking (that is for a ductwork contractor)
- A broken extract fan that won’t run
If you are not sure, just phone us on 0345 646 2711, or send details by email and we will give you a straight answer before booking.

What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
