Kitchen extracts in King's Walden
According to Food Standards Agency records, there are about 3 pubs, bars and clubs within about 1.5 miles of central King's Walden. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. King's Walden sits within the area of 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. Environmental health officers from North Hertfordshire council inspect food businesses in King's Walden. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
If your kitchen is in a listed or historic building, like the houses around King's Walden (Knebworth House is about 4.7 miles south-east), fitting access panels needs care. Church and community hall kitchens, near Church of St Mary or anywhere around King's Walden, are easy to forget, but their extracts collect grease like any other. Bursars and site managers at schools such as Breachwood Green Junior Mixed and Infant School tend to book extract cleaning for when the kitchen is empty.

How we handle kitchen extract cleaning in King's Walden
Every time food is cooked, warm vapour carries fat up into the extract. It cools inside the duct and settles as a sticky film that thickens month by month. That layer will burn, and a proper clean removes it before it becomes a fire risk. If you have poor airflow at the canopy and fat running down the canopy edge, we can help.

The fire risk in a kitchen extract sits in the parts nobody sees: the plenum, the duct and the fan, which is why a TR19® clean in King's Walden goes well beyond the canopy.
Work in a small place like King's Walden starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
How we price kitchen extract cleaning
The diagnosis comes before the price. The main factors are:
- The scale of the work
- Whether it’s a one-off visit or part of a schedule
- Travel, parking and unloading
- The condition we find in the survey
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, call us on 0345 646 2711, or send details by email for straight advice and a fixed quote.
Helping us quote
To speed up the quote, please include:
- The site address and the type of premises
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, call us on 0345 646 2711 or use the quote form.
How the job changes from site to site
Schools, hospitals and care homes
School, hospital and care home kitchens often have fixed hours and long holidays, so cleans can be booked when the kitchen is closed. The certificate goes straight into the site’s maintenance records.
Grease filters
We clean the grease filters as part of the job, and put back so they seat correctly. We’ll tell you if any need replacing.
Why deal with it now?
There’s no law that names TR19, but the Fire Safety Order 2005 still applies. The responsible person must assess and reduce fire risk, which in a kitchen includes the grease in the extract. TR19 is the benchmark insurers, fire officers and EHOs look to. It’s simpler to plan the work at King's Walden now than to arrange it in a hurry later.
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, ring 0345 646 2711 or drop us a line, and we will explain what it covers.

Multi-site and managed buildings
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
Looking after it afterwards
After the visit, a few habits help the work last:
- Keep to the recommended cleaning interval
- Run the extract fan throughout cooking
- Report grease drips, smells or fan noise straight away
- Clean grease off the canopy surfaces regularly
After cleaning, we re-test the same points we measured at the start, giving you before and after readings alongside the pictures. A TR19 certificate follows, issued through the BESCA Vent Hygiene Elite portal.
Stick to the cleaning interval on the certificate. If the kitchen starts cooking longer hours, the interval should be looked at again, and grease readings will show it.
Common questions in King's Walden
Which fire service covers King's Walden?
That’s 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.
Do you work overnight in King's Walden?
Yes. We work evenings, overnight and at weekends. It means the site in King's Walden keeps running as normal. Your opening times are the first thing we ask for.
What should I send you?
Some pictures and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.
Are you accredited for kitchen extract cleaning?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
What does a TR19 kitchen extract clean include?
A TR19 Grease clean covers the full extract route, not just the canopy. That means canopy, plenum, filters, ducts, risers, fan and discharge, reached through access panels where needed.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Do I have to clean my extract to TR19 by law?
TR19 is not written into law, 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 I get after the clean?
A TR19 certificate and a photo report. Certificates are issued through the BESCA Vent Hygiene Elite portal, and the report includes before and after pictures, grease readings and the recommended next clean date.
What we do, step by step
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the kitchen extract cleaning, tidy up and leave you the report. On site, the work takes a few hours for a small kitchen, longer for a large system. Photos of the system and how to reach it help us plan a visit to King's Walden.
- First comes a survey of the whole system, by pictures or a visit.
- We measure the grease at set points along the system, then give you a fixed price.
- Once the kitchen has closed and the equipment has cooled, we sheet and protect the area.
- The whole route is cleaned, from the canopy through the ductwork to the fan and the discharge.
- Finally the system is re-tested and photographed, and the certificate and report follow.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about permits to work or site inductions
