Ductwork cleaning for kitchens and businesses in Great Amwell
We treat ductwork like a doctor treats arteries: diagnose where grease has built up, clear it and confirm the result. Readings taken before and after show the difference, alongside before and after pictures. Common call-outs are for sections of duct with no access panels and smells of old cooking grease from the ductwork, on horizontal duct runs, bends and junctions and attenuators.
In a small place like Great Amwell, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Part by part
Bends and transitions
Transitions from the canopy spigot into the duct catch a lot of grease. We clean it from the canopy side or through a nearby panel.
Vertical risers
Cleaning a riser needs access along its height. Where it can’t be reached safely, the report says so.
What we’re called out for in Great Amwell
Slow air leaves the most grease behind. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
The symptoms we’re asked about most are:
- Duct runs that cannot be reached
- Duct runs with no cleaning record
- Stale grease odours from the duct
- An insurer asking for TR19 evidence
Healthcare kitchens, like those at hospitals such as Hertford County Hospital (about 3.1 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands.
Questions to ask before you book
- When they can work, and whether that’s outside your opening hours
- What happens if part of the system can’t be accessed
- Whether a survey comes first
- What’s included in the scope, part by part
Honest limits
In fairness, some problems need a different fix:
- Parts of the duct with no way in
- Fire dampers that do not close (they need testing and remedials)
- Undersized or badly laid-out ducts
Not sure which it is? You can phone us on 0345 646 2711 or use the quote form and we’ll tell you honestly before you book.
Parts of the system we cover

What ductwork cleaning looks like in Great Amwell
The FSA’s food hygiene register includes about 27 pubs and bars in Great Amwell and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Fire safety in Great Amwell falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Great Amwell, food businesses are inspected by environmental health officers from East Hertfordshire council. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready.
For kitchens close to St Margarets (Herts) station, where the day often starts early and ends late, the extract can be cleaned overnight. Term dates shape school work: for a school like Presdales School, an extract clean fits neatly into a half-term or summer break.

For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
How the visit works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes from a few hours to more than one visit, depending on duct length and access, and we clear up before we go. The timing of a visit to Great Amwell is set by you, and the travel is our side of the planning.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- The duct is signed off with readings, pictures and a next clean date.
Preparing for the visit
- Agree a time when the area can be out of use
- Mention any parking or loading restrictions
- Let us know about permits to work or site inductions
Getting a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To get going, give us a ring on 0345 646 2711, or send details by email.
Advice
Aftercare tips
Think of this as the after-treatment advice, in brief:
- Make sure filters are seated properly
- Book the next clean before the recommended date
- Run the extract fan throughout service
- Consider fitting panels where the report shows gaps
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.
Book the next duct clean before the date passes. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
Your questions about ductwork cleaning in Great Amwell
Do you work overnight in Great Amwell?
Yes, nights and weekends are routine for us. It means the site in Great Amwell keeps running as normal. Just ring 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Is Great Amwell within the area you cover?
Yes. Great Amwell is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you come out in an emergency?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Who is responsible for fire safety on the premises?
That depends on who controls the premises. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Do we lose a day’s trading?
Not typically. Visits are timed for when the area is closed, such as overnight or at a weekend, so the site can carry on as normal.
Can one contract cover all our sites?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Leave it or put it right?
There’s no law that names TR19. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. It’s simpler to plan the work at Great Amwell now than to arrange it in a hurry later.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before we start.
