Questions from Thorley
Do you work at weekends in Thorley?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Thorley needn’t be disturbed. Let us know the hours you’re closed and we will book within them.
Who enforces fire safety at workplaces in Thorley?
It’s Hertfordshire Fire and Rescue Service, which covers Thorley. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
Are you insured?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
How do you protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Who is the responsible person?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. If you are not sure, check your lease and fire risk assessment.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Ductwork cleaning for kitchens and businesses in Thorley
Nobody sees duct grease building, so nobody notices it until something goes wrong. 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. We’re often asked to deal with smells of old cooking grease from the ductwork and thick crusts of old grease along the duct, on bends and junctions, horizontal duct runs and vertical risers.
Somewhere as small as Thorley, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What affects the quote in Thorley
The survey tells us what the work involves. The main factors are:
- How easy every part is to reach
- The condition we find in the survey
- Working hours and out-of-hours timing
- The size of the system
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before we start.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Any access panels or hatches you can see
- Wide pictures of the system and the area around it
- The roof, plant room or outside wall the system runs to
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
If you need ductwork cleaning in Thorley, call 0345 646 2711, or send details by email. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. A fixed quote usually follows within one working day.

What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
How it works
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. The visit takes from a few hours to more than one visit, depending on duct length and access. Pictures of the system and its access let us plan the work in Thorley before we set off.
- 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.
- Bends, risers and the base of each riser get extra attention.
- The duct is signed off with readings, photos and a next clean date.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Tell us about site rules, permits or sign-in
- Mention any locked doors, roof access or ceiling voids
Get a fixed quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before any work starts.
Advice
How the job changes from site to site
Bends and transitions
A bend can hold far more grease than a straight run of the same length. It’s scraped out and degreased, and test it before and after.
Vertical risers
Risers are cleaned through panels at different levels. Any part that cannot be safely reached is recorded.
Ductwork cleaning around Thorley
Look up Thorley on the FSA’s food hygiene register and you’ll find about 15 restaurants, cafés and works canteens and about 9 sandwich bars and takeaways within about 1.5 miles of central Thorley. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. It’s East Hertfordshire council that sends environmental health officers to food businesses in Thorley. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready. Thorley is covered by Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Church and community hall kitchens, near Parish Church of St James the Great or anywhere around Thorley, are easy to forget, but their extracts collect grease like any other. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Much Hadham Palace is about 2.9 miles west), access may need planning. Healthcare kitchens, like those at hospitals such as Herts and Essex Hospital (about 1.7 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.
Thorley is about 1 mile south-west of Bishop's Stortford, in Hertfordshire.

Across Hertfordshire, we cover 381 places, Thorley among them. Our Chelmsford page covers sites nearby (17 miles or so).

Why it’s worth doing now in Thorley
Dealing with the ductwork in Thorley now beats dealing with it after a problem. It takes a shift or more, depending on the length of the runs and the number of access points, and we work evenings, overnight and weekends. Rural sites can’t always move to another kitchen or room when something fails.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, phone us on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

- One number for every site across the South East and London

When something else is needed
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Fire dampers that don’t close (they need testing and remedials)
- An extract fan that has stopped working
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
If you’re not sure, just give us a ring on 0345 646 2711 or use the quote form and we’ll give you a straight answer before you book.
