Hertfordshire · Kitchen extract cleaning
Chiswell Green kitchen extract cleaning
TR19 grease cleaning of complete kitchen extract systems, from canopy to discharge for commercial sites in Chiswell Green and across Hertfordshire. CHAS, SafeContractor and ISO 9001, and fully insured.
- An extract that no longer clears the smoke
- A kitchen with no current TR19 certificate
- Extraction mentioned at an environmental health visit
For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
Commercial kitchen extraction cleaning in Chiswell Green
Has the extract gone a while without a clean, or has the paperwork gone missing? Just give us a ring on 0345 646 2711, or send details by email with pictures of the canopy and filters, and you’ll have a fixed quote for kitchen extract cleaning in Chiswell Green, typically within one working day. If you are dealing with poor airflow at the canopy and a TR19 certificate needed for the insurer, we can put it right. If you need a kitchen extract clean in Chiswell Green, you get one team and one number for every site, wherever you are in Hertfordshire.
BESA sets minimum intervals by hours of cooking a day: every 3 months for 12–16 hours, every 6 months for 6–12 hours and every 12 months for 2–6 hours, adjusted by what the grease readings show.
In a smaller place like Chiswell Green, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Flag any change in how the extract sounds or works
- Clean the grease filters regularly between TR19 cleans
- Do not let the canopy gutters overflow
- Keep the TR19 certificate and photo report in the maintenance log
After cleaning, we re-test the same points we measured at the start, so you can see the difference in numbers as well as photos. Your TR19 certificate is then issued through the BESCA Vent Hygiene Elite portal.
Keep the fan on throughout service. Switching it off early leaves vapour to settle on the canopy and plenum, and the next clean has more to do.
What happens on the day
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes as long as the system needs, from a few hours to several planned visits. Evenings, weekends or a closed day all work for a site in a place like Chiswell Green.
- You send photos or we visit, and the system is surveyed from canopy to discharge.
- Grease thickness is measured and the price is fixed before work starts.
- The kitchen is closed, the equipment cooled and everything nearby protected.
- Filters, canopy and plenum are cleaned, then the ducts, risers, fan and discharge.
- Readings are repeated, photos taken, and your TR19 certificate and photo report issued.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know about permits to work or site inductions
- Make sure someone can let us in and lock up afterwards

To help us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711, or send details by email.

Grease, kitchens and Chiswell Green
Food Standards Agency records include about 7 pubs and bars in and around Chiswell Green, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Fire safety in Chiswell Green 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. Kitchens in Chiswell Green get their food hygiene inspections from St Albans City council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.
If you run a church or community hall kitchen, near St. Stephen's Church or elsewhere in Chiswell Green, its extract still collects grease from every lunch and event. Commuter trade near Park Street station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Chiswell Green is Napsbury Hospital, about 2.1 miles east.

Common questions in Chiswell Green
Which fire and rescue service is responsible for Chiswell Green?
Fire safety enforcement in Chiswell Green is handled by Hertfordshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can you come to Chiswell Green after we close?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Chiswell Green needn’t be disturbed. Your opening times are the first thing we ask for.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Each site gets its own report and photos.
Do you work in Chiswell Green?
Yes. We cover Chiswell Green and the rest of Hertfordshire, as part of our work across South East England and London. To book, call us on 0345 646 2711 or email us.
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. TR19 is the standard insurers and fire officers expect, and many policies require it.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
How long will the clean take?
Short systems are done in a few hours, but large systems may be spread over more than one visit. Your quote says how long to expect.
Different parts, different methods
Schools, hospitals and care homes
School kitchens can look lightly used but still need a TR19 clean at least every 12 months under BESA guidance. Holidays make it simple to schedule.
Ductwork and risers
Grease builds up most where the duct turns. Those are among the points where we take readings before and after, so the report shows the difference.
What affects the quote in Chiswell Green
You will get a fixed price before we start. It takes into account:
- A single visit or a regular plan
- The condition of the system
- How big the system is
- Any permits to work or inductions
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
Helping us quote
We can often survey from pictures. Try to include:
- How we’d reach plant on a roof or in a plant room
- Your opening hours and when the area is out of use
- Where the site is and what kind of site it is
- The paperwork from the last visit, if you have it
Quotes are quick. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
