Kitchen extract cleaning in Old Knebworth, Hertfordshire
Kitchen extract cleaning for Old Knebworth, with a survey first and a report with pictures at the end. Call for a fixed quote.
- A kitchen with no current TR19 certificate
- Rancid smells from grease in the duct
- A new tenancy or takeover with no cleaning history
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
TR19 kitchen extract cleaning in Old Knebworth
A kitchen extract system is far more than the canopy you can see. Beyond the filters run the plenum, the ducts and risers, the fan and the point where air leaves the building, and grease settles in every one of them. Our clean follows the air from canopy to discharge, cleaning to BESA TR19® Grease. The work covers plenums and filters, vertical risers and horizontal duct runs, and common reasons people get in touch are years of baked-on grease in the ducts and grease dripping from the canopy or filters. If you need a kitchen extract clean in Old Knebworth, one call covers the survey, the clean and the paperwork, wherever you are in Hertfordshire.
Access decides how thorough a clean can be. Where a duct run has no panels, we say so on the report and can fit new ones.
For a kitchen in or near Old Knebworth, the visit is planned around opening hours and the journey, 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.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

When it’s something else
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- Blocked drains from a neglected grease trap (a separate service)
- A fan motor or bearings that have failed (that needs a fan repair or replacement)
- Fire dampers that will not close (that needs damper testing and remedials)
Not sure which it is? You can call 0345 646 2711 or send us an email and we will tell you honestly before you book.
What the work covers
- Discharge points
- Vertical risers
- Horizontal duct runs
- Canopies and hoods
- Extract fans
- Plenums and filters
How the job changes from site to site
Restaurant and pub kitchens
Losing a service isn’t an option for most restaurants and pubs. Overnight and weekend cleans keep the kitchen trading, and hand back a clean kitchen ready to cook.
Canopy and plenum
Canopies vary from a single hood to long runs over several appliances, every section is cleaned and recorded in the photo report before and after.
Why act early in Old Knebworth
TR19® isn’t law, but the Regulatory Reform (Fire Safety) Order 2005 is. It puts a duty on the responsible person to assess and reduce fire risk, and in a kitchen that means keeping extract grease under control. TR19 is the benchmark insurers, fire officers and EHOs look to. In a place like Old Knebworth, ductwork and fans are easy to forget until something goes wrong.
What you pay reflects the actual work. That is why we survey first, from photos or on site, and why the quote is fixed before we start.

What we do, step by step
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes one visit for most kitchens, while large or complex systems may need more than one. For a village or hamlet like Old Knebworth, tell us about narrow lanes, gates and parking when you book.
- 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.
- Canopy, plenum, filters, duct runs, risers, fan and discharge are all cleaned to TR19® Grease.
- Finally the system is re-tested and photographed, and the certificate and report follow.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Clear loose items from the work area
- Mention any sign-in, permit or induction we need

Questions from Old Knebworth
Who enforces fire safety at workplaces in Old Knebworth?
It’s Hertfordshire Fire and Rescue Service, which covers Old Knebworth. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can you come to Old Knebworth after we close?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Which parts of the extract do you clean?
Everything from canopy to discharge: canopy inside and out, plenum, grease filters, ductwork, risers, extract fan and discharge, plus attenuators where fitted. Anything we can’t reach is recorded on the report.
Do you cover Old Knebworth?
Yes. Our technicians work in Old Knebworth, within the South East and London area we cover.
What do I get after the clean?
You receive a TR19 certificate and a photo report. Certificates are issued through the BESCA Vent Hygiene Elite portal, and the report shows before and after pictures, readings, any areas not reached and the next clean date.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before work begins, and waste is contained as we go. Before we leave, we tidy up and clean down.
How often does a kitchen extract system need cleaning?
That comes down mainly to daily cooking hours. Heavy use of 12 to 16 hours a day calls for a clean at least every 3 months under BESA guidance, and lighter use less often. We’ll recommend a date after measuring the grease.
Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Switch the fan on before cooking starts
- Refit filters properly after cleaning
- Tell us when the extract starts to drip or smell
- Keep the baffle filters clean
When the clean is finished, grease readings are taken again at the same points, so you can see the difference in numbers as well as photos. A TR19 certificate follows, issued through the BESCA Vent Hygiene Elite portal.
Regular filter cleaning is the simplest thing a kitchen can do. Clean, well-fitted filters catch more fat before it reaches the duct, so the ductwork stays cleaner for longer.
Grease, kitchens and Old Knebworth
Food Standards Agency data counts about 17 restaurants, cafés and works canteens and about 11 takeaways and sandwich shops within 1.5 miles or so of the middle of Old Knebworth. Those that fry, grill or roast under a canopy need their extracts cleaned at intervals set by how long they cook. In Old Knebworth, food businesses are inspected by environmental health officers from North Hertfordshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Old Knebworth falls to Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
If you run a church or community hall kitchen, near Church of St Mary and St Thomas or elsewhere in Old Knebworth, its extract still collects grease from every lunch and event. Healthcare kitchens, like those at hospitals such as Lister Hospital (about 3.7 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Knebworth House is about 0.2 miles north-west), access may need planning.
