Kitchen extract cleaning for kitchens and businesses in Clothall
The part of the system nobody sees is often the dirtiest. 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. Any section we cannot reach is recorded on the report, and new panels can be fitted. Common call-outs are for fat running down the canopy edge and an extract that has never been cleaned to TR19, across plenums and filters, extract fans and vertical risers. Kitchen extract cleaning, TR19 cleaning, extraction cleaning: whatever you call it, it’s the job we do every week across Hertfordshire.
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 Clothall goes well beyond the canopy.
Work in a small place like Clothall starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

FAQs for Clothall
Can a school canteen extract in Clothall be done out of term time?
Yes, and it’s the easiest time to do it. Around Clothall, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Just give us a ring on 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Will you come out to Clothall?
Yes, we work in villages as well as towns, and Clothall is covered. A survey first, from photos or a visit, means we arrive with the right kit.
How long does it take to clean a kitchen extract system?
It takes a few hours for a small kitchen, longer for a large system. We will confirm the time when we quote.
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, while TR19® Air covers other supply and extract ductwork.
How much does kitchen extract cleaning cost in Clothall?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll typically reply within one working day.
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.
What about areas you cannot get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.

Clothall kitchens: local notes
Look up Clothall on the FSA’s food hygiene register and you’ll find about 3 cafés, restaurants and staff canteens within 1.5 miles or so of the middle of Clothall. Those that fry, grill or roast under a canopy need their extracts cleaned at intervals set by how long they cook. Clothall is covered by Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Food hygiene inspections in Clothall are the job of North Hertfordshire council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Healthcare kitchens, like those at hospitals such as Lister Hospital (about 4.1 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands. For schools such as Weston Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.
Clothall is about 3 miles east of Letchworth, in Hertfordshire. We carry out kitchen extract cleaning for commercial premises of every kind in Clothall and the rest of Hertfordshire. Clothall is one of 381 towns, villages and districts in Hertfordshire we cover for commercial clients. You can also see our page for Milton Keynes, roughly 27 miles from Clothall.

The process
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes anything from a few hours to a full night, depending on the size of the system. A few photos of the system help us make the most of a visit to a place like Clothall.
- We start with a survey, so we know every part of the system before we quote.
- Grease readings are taken at set points and you get a fixed quote.
- On the day, cooking equipment is switched off and left to cool, and everything nearby is sheeted.
- Canopy, plenum, filters, duct runs, risers, fan and discharge are all cleaned to TR19® Grease.
- Readings and photos are taken again, and you receive a TR19 certificate and photo report.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Clear loose items from the work area
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
Some systems can be priced from photos; others need a survey. 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
Leave it or put it right?
Environmental health officers inspect food businesses, in Clothall as everywhere else, and they look at the cleanliness of the premises and equipment, extraction included. A clean extract is one less thing to worry about on the day. It’s worth booking a check, because nobody sees inside a duct day to day.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
Why us?
- A written report with pictures after each visit
- A single point of contact for sites across the South East and London
- Fixed quotes from a survey or photos
- Ventilation hygiene specialists since 2009

Between visits
So the system stays in good health:
- Clean grease off the canopy surfaces regularly
- Diarise the next clean as soon as you get the certificate
- Run the extract fan throughout cooking
- Wash or exchange the filters often
We hand the kitchen back clean, with the sheeting removed and waste taken away. Grease and dirty water are collected and taken off site, and equipment can be switched back on once we’ve gone.
Tell whoever looks after the system when something changes. Grease dripping from the canopy, a burning smell or a fan that sounds rough are all signs of build-up, and a grease thickness test can confirm it.
Signs you need kitchen extract cleaning in Clothall
The reason for all this is fire. Flames from a pan or grill can be pulled into the canopy by the fan, and once grease in the duct catches, fire can spread through the building’s ductwork. That’s why controlling extract grease belongs in the fire risk assessment.
Common reasons sites call us include:
- Cleaning needed before an insurance renewal or survey
- Ductwork thick with old, hardened grease
- An extract that no longer clears the smoke
- An extract that has never been cleaned to TR19
A hall kitchen that only cooks for events, whether near Church of St Mary or elsewhere in Clothall, still needs its extract cleaned, just less often.
Comparing quotes
- Whether the whole system is included, or only the parts that are easy to reach
- How VAT is shown on the quote
- Whether the price is fixed
- Whether inaccessible sections are listed on the report
Honest limits
To be straight with you, there are a few things this work won’t fix:
- An undersized canopy or fan
- Fire dampers that will not close (that needs damper testing and remedials)
- A fan motor or bearings that have failed (that needs a fan repair or replacement)

What affects the cost of kitchen extract cleaning
The diagnosis comes before the price. The main factors are:
- How big the system is
- Whether several sites go on one quote
- How easy every part is to reach
- Where the site is and how we reach it
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 make a difference.
Helping us quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
- Where the site is and what kind of site it is
- Photos showing the whole system and its surroundings
If you need kitchen extract cleaning in Clothall, call us on 0345 646 2711, or email photos. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. A fixed quote normally follows within one working day.
What the work involves, part by part
Canopy and plenum
Grease meets the system first at the canopy and the plenum behind the filters. Both are scraped and degreased inside and out, with the filter housing cleaned too.
Grease filters
Gaps around filters let fat through to the duct. Each filter is checked as it goes back in, and flag any that don’t.
