Kitchen extract cleaning in Welwyn, Hertfordshire
Kitchen extract cleaning in Welwyn from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Rancid smells from grease in the duct
- An extract that no longer clears the smoke
- A kitchen with no current TR19 certificate
Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Flag any change in how the extract sounds or works
- Keep the baffle filters clean
- Diarise the next clean as soon as you get the certificate
- Never cook with filters missing or out of place
Any section without access is marked on the report. That is part of an honest TR19 clean, not a failing, and we can fit access panels so it’s reached next time.
Book the next clean before the last one runs out. If the kitchen starts cooking longer hours, the interval should be looked at again, and grease readings will show it.
How we handle kitchen extract cleaning in Welwyn
Across Welwyn, we clean kitchen extract systems to BESA TR19® Grease. The job starts with a survey and grease readings, then works through canopy, plenum, filters, ductwork, fan and discharge. You get a TR19 certificate and a photo report at the end. If you’re dealing with fat running down the canopy edge and an extract that has never been cleaned to TR19, we can put it right. Some call it canopy cleaning, others extract cleaning or duct cleaning, but in Welwyn, as everywhere, the insurer wants the full system cleaned, not just the hood.
What can be cleaned depends on what can be reached. Sections without access panels are recorded on the report, and new panels can be fitted so they’re cleaned next time.
In a smaller place like Welwyn, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
A written report with photos follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
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 on a regular cycle.
Kitchen extract cleaning around Welwyn
The Food Standards Agency lists about 11 bars, pubs and nightclubs as registered food businesses within about 1.5 miles of central Welwyn. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Environmental health officers from Welwyn Hatfield council inspect food businesses in Welwyn. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Welwyn is covered by Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
A hospital like Queen Elizabeth II Hospital, about 3.5 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Where a hall near Parish Church of St Mary, or anywhere in Welwyn, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What happens if it’s left?
Any food business in Welwyn can expect visits from the council’s environmental health officers, and they look at the cleanliness of the premises and equipment, extraction included. Keeping the extract clean helps the whole kitchen pass muster. A site near Welwyn that has to close at short notice is hard to cover for.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.

What we do, step by step
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. In a smaller place like Welwyn, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- Diagnosis comes first, with a survey of the system and how it’s reached.
- Grease readings set the baseline, and a fixed quote follows.
- 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.
- The sign-off: post-clean readings, a TR19 certificate and a photo report with the next clean date.
How to prepare
- Tell us about site rules, permits or sign-in
- Make sure equipment near the work can be switched off and left to cool

How we price kitchen extract cleaning
You will get a fixed price before work begins. It takes into account:
- How big the system is
- Whether several sites go on one quote
- Access, including roofs, risers and ceiling voids
- A single visit or a regular plan
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.
Asking for a quote
When you call or email, it’s useful to have:
- The paperwork from the last visit, if you have it
- Any access panels or hatches you can see
- Wide photos of the system and the area around it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
To help us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Then call 0345 646 2711 or drop us a line.
Part by part
Canopy and plenum
The canopy catches the vapour, and the plenum behind the filters is where it first condenses. Both are scraped and degreased inside and out, with the filter housing cleaned too.
Restaurant and pub kitchens
Grills, fryers and woks send a lot of fat into the extract, and measured readings show whether the minimum interval is enough.
When to call us in Welwyn
What’s on the menu matters as much as how much is cooked. Frying, grilling and roasting send far more fat into the canopy than steaming or boiling, which is why grease readings matter more than the calendar.
Most sites get in touch after spotting one of these:
- Grease smells coming from the extract
- Extraction mentioned at an environmental health visit
- Ductwork thick with old, hardened grease
- Poor airflow at the canopy
School kitchens, at schools like Monk's Walk School for example, are normally cleaned in the holidays so no lunches are lost.
What your quote should include
- What happens if part of the system can’t be accessed
- Whether the whole system is included, or only the parts that are easy to reach
- How they set the interval to the next visit
- Whether the price is fixed
Questions from Welwyn
Do you work overnight in Welwyn?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Welwyn needn’t be disturbed. Your opening times are the first thing we ask for.
Do you work in villages like Welwyn?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.

Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Do you clean the whole extract system or just the canopy?
A TR19 Grease clean covers the full extract route, not just the canopy. Canopy, plenum, filters, ductwork, risers, fan and discharge are all included, reached through access panels where needed.
How long will the clean take?
That depends on the size of the system, the amount of grease and the number of access points. Most jobs take one visit for most kitchens, while large or complex systems may need more than one.
How do you protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
