How we handle kitchen extract cleaning in Ayot Green
Cooking sends fat-laden vapour into the canopy with every service. It cools inside the duct and settles as a sticky film that thickens month by month. That film is fuel, and cleaning the whole system is how you keep it under control. The work covers horizontal duct runs, plenums and filters and vertical risers, and the jobs we see most are a system with no record of a TR19 clean and a new tenancy or takeover with no cleaning history. For TR19 kitchen extract cleaning in Ayot Green, you get one team and one number for every site.
A clean in Ayot Green covers the canopy, plenum, filters, ductwork, risers and fan, and the discharge where it can be reached.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

The process
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. A few photos of the system help us make the most of a visit to a place like Ayot Green.
- 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.
- After the kitchen closes, we sheet the area and set up to contain grease and water.
- 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.
How to prepare
- Clear the space around the work
- Let us know about permits to work or site inductions
- Agree a time when the area can be out of use
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, you get a fixed price before any work starts.
Advice
Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Grease, kitchens and Ayot Green
The FSA’s data shows about 13 bars, pubs and nightclubs registered within roughly a mile and a half of the centre of Ayot Green. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Hertfordshire Fire and Rescue Service covers Ayot Green. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Ayot Green, food businesses are inspected by environmental health officers from Welwyn Hatfield council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
Healthcare kitchens, like those at hospitals such as Queen Elizabeth II Hospital (about 2.8 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands. If you look after a school kitchen, at a school such as Monk's Walk School or anywhere near Ayot Green, the holidays are the usual time for a TR19® clean.

In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Keep the extract on whenever the range is lit
- Never cook with filters missing or out of place
- Give the canopy a daily wipe
- Don’t let the canopy gutters overflow
After cleaning, we re-test the same points we measured at the start, giving you before and after readings alongside the photos. Your TR19 certificate is then issued through the BESCA Vent Hygiene Elite portal.
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.
Signs you need kitchen extract cleaning in Ayot Green
Cooking fat leaves the pan as a fine vapour. As the air cools on its way through the duct, the fat condenses and sticks, and the layer grows a little with every meal cooked. The grease filters stop some, never all of it.
Keep an eye out for any of the following:
- Poor airflow at the canopy
- Ductwork thick with old, hardened grease
- A new tenancy or takeover with no cleaning history
- Grease drips onto cooking equipment
Historic houses near Ayot Green, such as Digswell House about 1.1 miles east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
Questions to ask before booking
- Whether the price is fixed
- What insurance they carry
- Whether the quote is based on a survey or pictures
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
What kitchen extract cleaning can’t fix
In fairness, there are a few things this work won’t fix:
- A fan motor or bearings that have failed (that needs a fan repair or replacement)
- A damper that sticks or has a damaged link
- Extraction that can’t cope with the cooking because of its design
If in doubt, call 0345 646 2711 or drop us a line and we’ll say what we think.

Your questions about kitchen extract cleaning in Ayot Green
Which fire authority looks after Ayot Green?
Fire safety enforcement in Ayot Green is handled by Hertfordshire Fire and Rescue Service. 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.
Can the work in Ayot Green be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. It means the site in Ayot Green keeps running as normal. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
Do you look at the system first?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
What information do you need?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we will ask.
Do insurers need proof of extract cleaning?
Grease-filled ducts can carry fire well beyond the kitchen. Many insurers require TR19 cleaning, and may refuse or reduce a claim without proof, so keep every certificate.
What happens to the waste?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.

Restaurant and pub kitchens
Restaurants and pubs tend to cook long hours with plenty of frying and grilling, so their cleaning interval is often 3 or 6 months under BESA guidance. Cleans are done after close, overnight or before opening.
Extract fan and discharge
Grease that reaches the fan coats the blades and the housing. We isolate it, open it up and degrease it.
