Common problems we fix in Marshalswick
In Marshalswick, as anywhere, grease gathers where the air slows down: in long flat runs, at bends and changes of direction, and in the fan housing. The cooler the duct, the more grease drops out of the air.
The symptoms we’re asked about most include:
- Rancid smells from grease in the duct
- A system with no record of a TR19 clean
- Poor airflow at the canopy
- Fat running down the canopy edge
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Batchwood Hall is about 2 miles west), access may need planning.
Before you book anyone
- How areas they can’t reach will be recorded
- Whether the figure could change on the day
- Proof of accreditation you can verify
- Proof of insurance
Kitchen extract cleaning in Marshalswick
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 each part collects grease. A TR19® Grease clean deals with the whole route, not only the parts on show. Typical jobs include an inspection that picked up a dirty extract and stale cooking odours from the system, across canopies and hoods, plenums and filters and extract fans. Hood cleaning is where most enquiries from Marshalswick start: a system that’s clean inside, not just on the surface, and a certificate that proves it.
BESA sets minimum intervals by hours of cooking a day: 3-monthly for heavy use, 6-monthly for moderate use and yearly for light use, with grease readings setting the real interval.
Around a smaller place like Marshalswick, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Marshalswick questions
Which fire service covers Marshalswick?
That is Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Who inspects food businesses in Marshalswick?
In Marshalswick, it’s St Albans City council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Is TR19 a legal requirement?
Strictly, the legal duty comes from the Regulatory Reform (Fire Safety) Order 2005, not from TR19. TR19 is the industry benchmark for meeting that duty in a kitchen extract, and an insurer may refuse or reduce a claim without it.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
What about areas you can’t get to?
Anything we cannot reach goes on the report, with pictures where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
What does a TR19 kitchen extract clean include?
Everything from canopy to discharge: canopy inside and out, plenum, grease filters, ductwork, risers, extract fan and discharge, plus attenuators where fitted. Any part without access is noted.
Will my insurer ask for a TR19 certificate?
Many insurers ask for proof of regular cleaning to TR19, and many policies require it. An insurer may refuse or reduce a claim if there’s no evidence, so it’s worth checking your policy wording.
Leave it or put it right?
Leaving the clean until the next refit doesn’t make the grease go away. Fat that was soft and easy to remove hardens with heat and time, which is slower to clean. Staying on a regular cycle keeps each clean manageable. Light use slows the build-up but does not stop it.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before any work starts.

What the work involves, part by part
Restaurant and pub kitchens
Grills, fryers and woks send a lot of fat into the extract, so grease readings help set the right interval.
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.
Kitchen extract cleaning around Marshalswick
Food Standards Agency records list about 83 restaurants, cafés and works canteens and about 33 takeaways and sandwich shops within roughly a mile and a half of the centre of Marshalswick. Wherever food is cooked under a canopy, the extract above it gathers grease and needs cleaning on a schedule. It’s St Albans City council that sends environmental health officers to food businesses in Marshalswick. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Marshalswick sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes as long as the system needs, from a few hours to several planned visits. Tell us about any gates, ladders or locked plant areas at your site near Marshalswick when you book.
- We start with a survey, so we know every part of the system before we quote.
- We measure the grease at set points along the system, then give you a fixed price.
- 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.
- We test again, photograph the result and issue your TR19 certificate and photo report.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us about site rules, permits or sign-in
- Clear the space around the work
Getting a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Switch the fan on before cooking starts
- Refit filters properly after cleaning
- Diarise the next clean as soon as you get the certificate
- Keep the cleaning records where you can find them
The certificate records when the clean was done, where and by whom. File it with the fire risk assessment and the maintenance log, so it’s to hand when an insurer, fire officer or EHO asks.
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.
