Kitchen extracts in Letchmore Heath
There are about 18 restaurants, cafés and canteens and about 7 takeaways and sandwich shops in Letchmore Heath and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Behind every canopy among them is a run of ductwork that collects grease out of sight. The fire and rescue service for Letchmore Heath is 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 Letchmore Heath get their food hygiene inspections from Hertsmere 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.
Where a hall near Church of St John the Baptist, or anywhere in Letchmore Heath, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (High Elms Manor is about 3.5 miles north-west), access may need planning.

Ductwork cleaning for kitchens and businesses in Letchmore Heath
We’ve been trading since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, with each certificate issued through the BESCA portal. We are often asked to deal with a rancid smell from the extract duct and fat dripping from the ductwork, across bends and junctions, access panels and multi-storey ducts.
Work in a small place like Letchmore Heath starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Signs you need ductwork cleaning in Letchmore Heath
The further the air travels from the cooking, the cooler it gets. As it cools, the grease it carries condenses onto the duct walls, so duct runs keep collecting grease long after the canopy.
Keep an eye out for any of the following:
- A duct clean needed for an insurer
- Grease pooling at the foot of the riser
- Stale grease odours from the duct
- Duct runs that can’t be reached
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Letchmore Heath is Shenley Hospital, about 2.6 miles north-east.
Questions to ask before you book
- Proof of accreditation you can verify
- Exactly which parts of the system are covered
- Proof of insurance
- If the quote is a fixed price or an estimate
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. 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.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Why it’s worth doing now in Letchmore Heath
A dirty duct is something insurers ask about. Many require cleaning to TR19, and they can refuse or reduce a claim without proof. Your certificate and photo report show the ducts were cleaned. A fault that closes a site in a village like Letchmore Heath affects everyone who depends on it.
The cost depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.

How it works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes a shift or more, depending on the length of the runs and the number of access points. A quick note on how to find the site and where to park makes a visit to Letchmore Heath run smoothly.
- We start by working out how the duct runs and where it can be opened.
- We measure grease thickness at set points before cleaning.
- We open the panels and scrape out the heaviest grease.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
How to prepare
- Tell us where we can park and unload
- Move anything stored near the system
- Mention any sign-in, permit or induction we need
How to get a quote
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
Related advice
Part by part
Vertical risers
A riser takes the duct up through one or more floors. Grease collects on the walls and at the foot of the riser, so the base is one of our test points.
Attenuators and discharge
At the end of the duct is the discharge. Grease can collect there and stain the area around it, so it’s cleaned as far as safe access allows.
When something else is needed
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Parts of the duct with no way in
- A damper stuck open in the duct
- A duct that is too small or badly routed for the kitchen (a design issue)
Not sure which it is? You can ring 0345 646 2711, or send details by email and we’ll tell you honestly before you book.

Letchmore Heath questions
Will you come out to Letchmore Heath?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Can the work in Letchmore Heath be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Letchmore Heath needn’t be disturbed. Just ring 0345 646 2711 or email us with your opening times and we’ll plan around them.
How do you protect the area?
Floors and surfaces near the work are sheeted before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
Is TR19 cleaning required by law?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The law behind it is the Fire Safety Order 2005, which applies in England and Wales.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
What affects the cost of ductwork cleaning
We quote each job individually. These are the things that affect it:
- How many systems or sites are involved
- The condition of the system
- Access, including roofs, risers and ceiling voids
- A single visit or a regular plan
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.
What we need to know
Photos let us diagnose from a distance. Try to include:
- The paperwork from the last visit, if you have it
- The site address and the type of premises
- Problems your staff have spotted
- Where the plant sits or the system leaves the building, such as a roof or outside wall
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711 or use the quote form.
