Why act early in High Leigh
TR19® is not law, but the duty to manage fire risk is. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and grease in the duct is part of that. Out of sight is the usual reason a rural system goes too long without attention.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, give us a ring on 0345 646 2711, or email photos for straight advice and a fixed quote.

Ductwork cleaning in High Leigh
Ductwork in High Leigh is cleaned the same thorough way as everywhere else we work: readings at set points, heavy grease scraped out by hand, then degreasing to suit the deposit. Post-clean readings and photos complete the record. Typical jobs include stale grease odours from the duct and proof of duct cleaning for the insurer, on attenuators, horizontal duct runs and multi-storey ducts.
In a village or hamlet like High Leigh, 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 report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
The process
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes a shift or more, depending on the length of the runs and the number of access points. For a village or hamlet like High Leigh, tell us about narrow lanes, gates and parking when you book.
- First we diagnose: the route, the access and the grease levels.
- You get a fixed price before work starts.
- Each section is cleaned in turn through its access panel.
- Bends, risers and the base of each riser get extra attention.
- The duct is signed off with readings, pictures and a next clean date.
Preparing for the visit
- Find the previous report, if there is one
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about parking and loading
Getting a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

When something else is needed
Some problems need a different service or another trade:
- Fire dampers that do not close (they need testing and remedials)
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
- An extract fan that has stopped working
If you’re not sure, just call us on 0345 646 2711 or email us and we’ll give you a straight answer.
What we work on in High Leigh
- Bends and junctions
- Vertical risers
- Multi-storey ducts
- Attenuators
- Horizontal duct runs
- Access panels
What the work involves, part by part
Vertical risers
Risers carry the extract up through the building to the roof. Grease runs down the walls and gathers at the base, so the base is one of our test points.
Horizontal duct runs
A long flat run cannot be cleaned from one end. Where the gaps between panels are too long, we record what couldn’t be reached and can fit extra panels.
High Leigh kitchens: local notes
Look up High Leigh on the FSA’s food hygiene register and you will find about 60 restaurants, cafés and canteens and about 21 takeaways and sandwich shops within 1.5 miles or so of the middle of High Leigh. Where they cook under a canopy, grease doesn’t stop at the filters: it settles along the duct and up the riser. Environmental health officers from Broxbourne council inspect food businesses in High Leigh. 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. Hertfordshire Fire and Rescue Service covers High Leigh. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Volunteers running a hall kitchen near Church of St Catherine & St Paul, or anywhere in High Leigh, may not know when the extract was last cleaned, and a grease test settles it. A hospital like Hertford County Hospital, about 3.5 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

What we’re called out for in High Leigh
Risers carry the extract up through the building. Grease collects on the riser walls and gathers at the bottom as liquid grease runs down. Access along its height is needed to clean it properly.
It’s time to book a visit if you see:
- A duct clean needed for an insurer
- Gaps where access panels were never fitted
- Hardened, baked-on grease in long horizontal runs
- High readings at a recent grease test
For schools such as Westfield Community Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Questions from High Leigh
Who would carry out a food hygiene inspection at a kitchen in High Leigh?
In High Leigh, it’s Broxbourne 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.
Can you get to a site in High Leigh?
Yes, High Leigh is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
How much does ductwork cleaning cost?
It depends on the site, so we quote each one individually. To get one, call 0345 646 2711 or use the quote form and tell us about the site and its opening hours.
Is a quote from pictures possible?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we normally come back within one working day. If pictures are not enough, we will survey first.
Do you install duct access panels?
Yes, extra panels can be fitted. That lets the next clean reach sections that were missed, and the report will show where they’re needed.
Do you survey before quoting?
Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
