What we’re called out for in Mackerye End
Air cools as it moves away from the canopy. As it cools, the grease it carries condenses onto the duct walls, so duct runs keep collecting grease long after the canopy.
Signs it’s time to call us include:
- Hardened, baked-on grease in long horizontal runs
- Duct runs that can’t be reached
- Proof of duct cleaning for the insurer
- Fat dripping from the ductwork
Where a hall near All Saints, or anywhere in Mackerye End, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Questions to ask before booking
- Proof of insurance
- What’s included in the scope, part by part
- Whether a written report and photos are included
- How areas they can’t reach will be recorded
How we handle ductwork cleaning in Mackerye End
Grease in a duct is hidden, which is exactly why it’s dangerous. A flare-up drawn up from the range can light it, and fire can then run along the ductwork to other parts of the building. Cleaning the duct takes that fuel away. If you’re dealing with a duct nobody has opened in years and duct runs that can’t be reached, we can help.
In a village or hamlet like Mackerye End, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
The paperwork matters as much as the work. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Between visits
Aftercare is simple, and it makes the next visit easier:
- Ask us about extra access panels where sections cannot be reached
- Don’t block access panels with shelving or stock
- Keep the fan on while anything is cooking
- Never cook with a filter missing
Grease readings are taken again at the same set points, so the report shows the before and after figures. Before and after pictures sit next to the numbers.
Keep to the cleaning interval on the report. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
What happens if it’s left?
Fire inside a duct is out of sight and out of reach. The duct can carry it to rooms, floors or roof spaces well away from the kitchen, which is why the duct matters as much as the canopy. Equipment tucked in a roof space or outbuilding near Mackerye End rarely gets looked at unless someone books it.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.

Kitchen extracts in Mackerye End
Food Standards Agency records include about 7 pubs and bars across Mackerye End and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Hertfordshire Fire and Rescue Service covers Mackerye End. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Kitchens in Mackerye End get their food hygiene inspections from St Albans City council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
Term dates shape school work: for a school like Sauncey Wood Primary School, an extract clean fits neatly into a half-term or summer break. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Shaw's Corner is about 2.3 miles east), access may need planning.

Common questions in Mackerye End
Can you work in Mackerye End outside opening hours?
Yes, out-of-hours work is a big part of what we do. It means the site in Mackerye End keeps running as normal. Tell us your opening hours when you ask for a quote.
Which council inspects kitchens in Mackerye End?
The local authority for Mackerye End is St Albans City council, and its environmental health team does the inspecting. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
How long will the duct clean take?
It depends on the length of the duct, the number of access panels and how much grease there is. Typically it takes a shift or more, depending on the length of the runs and the number of access points.
Do you install duct access panels?
Yes, as part of our fits and repairs work. We place them where they help most, and we’ll recommend where.
Do we lose a day’s trading?
Not usually. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so you keep your normal hours.
Is TR19 cleaning required by law?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Fixed quotes for ductwork cleaning in Mackerye End
We don’t publish a price list, because sites vary so much. What we look at:
- Working hours and out-of-hours timing
- Where the site is and how we reach it
- The condition of the system
- The size of the system
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before work begins.
Helping us quote
We can often survey from pictures. The most useful are:
- The paperwork from the last visit, if you have it
- Any access panels or hatches you can see
- The site address and the type of premises
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

What else we do in Mackerye End
When it’s something else
Not every problem is solved by ductwork cleaning, and we’d rather say so up front. It won’t put right:
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- Duct sealed behind fixed ceilings or walls
- A worn-out fan that needs replacing
Not sure which it is? You can call us on 0345 646 2711, or email photos and we’ll tell you honestly before booking.
What the work covers
- Horizontal duct runs
- Access panels
- Vertical risers
- Attenuators
- Multi-storey ducts
- Bends and junctions
Different parts, different methods
Multi-storey and shared buildings
A fire in a duct in a shared building can affect far more than one kitchen, so the responsible person has more reason to keep it clean. The paperwork suits landlords and managing agents.
Vertical risers
A riser takes the duct up through one or more floors. Grease runs down the walls and gathers at the base, so the base is one of our test points.
How the visit works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes a shift or more, depending on the length of the runs and the number of access points. Somewhere like Mackerye End, lanes, gates and parking are worth mentioning in advance.
- We map the duct route and check where the access panels are.
- Grease readings are taken at set points along the duct.
- Through the access panels, thick grease is removed by hand first.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- We test again, take pictures and note any part that couldn’t be reached.
Getting ready for the visit
- Let us know when the site is closed or quiet
- Let us know about permits to work or site inductions
- Mention any parking or loading restrictions
