How we handle ductwork cleaning in Hensting
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. Removing it is the whole point. We are often asked to deal with high readings at a recent grease test and a duct clean needed for an insurer, on horizontal duct runs, multi-storey ducts and vertical risers.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Different parts, different methods
Multi-storey and shared buildings
Long ducts in larger buildings can mean several visits. We agree a sequence that suits the building, out of hours where possible.
Horizontal duct runs
Flat runs of duct link the canopy to the riser or the outside wall. They collect grease as the air cools and slows, and we clean them section by section through access panels.
The process
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. The work itself takes anything from a few hours to several visits, depending on the length of duct. Rural roads and tight entrances are worth telling us about before a visit to Hensting.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Dig out any earlier paperwork for the system
- Let us know how we reach the system, including roofs, risers and plant rooms

What ductwork cleaning cannot fix
We won’t sell you work that does not address the problem, so here are the limits:
- An extract fan that has stopped working
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- Undersized or badly laid-out ducts
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we will tell you honestly.

In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Kitchen extracts in Hensting
There are about 5 restaurants, cafés and canteens within roughly a mile and a half of the centre of Hensting, according to the Food Standards Agency’s register. The duct above a busy canopy coats itself in grease long before anyone sees it. Fire safety in Hensting falls to Hampshire and Isle of Wight 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. Environmental health officers from Winchester City council inspect food businesses in Hensting. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand.
If you run a church or community hall kitchen, near Church of the Holy Trinity or elsewhere in Hensting, its extract still collects grease from every lunch and event. If you run catering at a healthcare site, such as a hospital like St John's Rooms And Chapel about 4.3 miles north, the extract may need cleaning more often than a part-time kitchen.

Why it’s worth doing now in Hensting
Grease narrows the duct and slows the air. The fan works harder, the kitchen gets hotter and smoke lingers at the canopy and grease can drip from duct joints. Rural sites cannot always move to another kitchen or room when something fails.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

Between visits
Results last longer with the right care. Here’s what we suggest:
- Check readings when the menu changes
- Do not switch the extract off early
- Ask us about extra access panels where sections can’t be reached
- Keep your cleaning records together
The report gives a recommended next clean date, based on the readings and your daily cooking hours, in line with BESA guidance.
Grease that never reaches the duct never needs cleaning out of it. Clean, properly seated filters are the duct’s best protection.

Landlords, agents and facilities managers
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
Hensting: your questions answered
Can you come to Hensting after we close?
Yes, we can come after you close and finish before you open. That way a site in Hensting doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Which fire service covers Hensting?
Hensting is in the area of Hampshire and Isle of Wight Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
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.
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’re not sure, check your lease and fire risk assessment.
How often does extract ductwork need cleaning?
BESA guidance sets minimum intervals by daily cooking hours: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Grease readings may show it needs doing sooner.
What paperwork do you give after a duct clean?
Every clean comes with a photo report, and a full TR19 clean also comes with a certificate issued through the BESCA Vent Hygiene Elite portal. File them with the fire risk assessment.
Can extra access doors be added to the duct?
Yes, as part of our fits and repairs work. Panels go where they give the best access to sections that couldn’t be reached, and we’ll recommend where.
