What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Ductwork cleaning for kitchens and businesses in Thedden
Ductwork in Thedden is cleaned the same thorough way as everywhere else we work: we test the grease first, remove thick deposits by hand and degrease what’s left. Readings are taken again afterwards and photos go into your report. If you are dealing with sections of duct with no access panels and an insurer asking for TR19 evidence, we can put it right, from vertical risers, attenuators and access panels onwards.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
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.

Your questions about ductwork cleaning in Thedden
Which environmental health team covers Thedden?
Kitchens in Thedden are inspected by East Hampshire council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you work at weekends in Thedden?
Yes, out-of-hours work is a big part of what we do. It means the site in Thedden keeps running as normal. Tell us your opening hours when you ask for a quote.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Are you insured?
Yes. We’re fully insured, and we can share the details when you need them.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
How often does extract ductwork need cleaning?
The duct is cleaned as part of the whole system, at intervals set by BESA guidance, ranging from 3-monthly to 12-monthly. Readings tell you if it needs to be more often.
Can extra access doors be added to the duct?
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.
What if part of the duct can’t be reached?
Without a way in, a section cannot be cleaned properly. We record those sections on the report and can fit access panels.
Multi-site and managed buildings
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
What ductwork cleaning looks like in Thedden
Food hygiene inspections in Thedden are the job of East Hampshire council’s environmental health team. 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. Hampshire and Isle of Wight Fire and Rescue Service covers Thedden. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
A hall kitchen that only cooks for events, whether near St Peter's or elsewhere in Thedden, still needs its extract cleaned, just less often. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Bentworth Hall is about 1 mile west), access may need planning.

Why deal with it now?
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. Out of sight is the usual reason a rural system goes too long without attention.

When to call us in Thedden
Slow air leaves the most grease behind. Flat runs, bends, reducers and the base of risers are the usual hotspots, and those are the points we pay most attention to.
The symptoms we are asked about most are:
- Years of grease along the duct floor
- A grease test showing the duct is overdue
- Fat dripping from the ductwork
- Gaps where access panels were never fitted
For schools such as Amery Hill School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.
Questions to ask before booking
- If the quote is a fixed price or an estimate
- How they set the interval to the next visit
- Whether a written report and pictures are included
- Proof of accreditation you can verify

Keeping the system healthy
So the system stays in good health:
- Run the extract fan throughout service
- Keep to the interval on the report
- Keep access panels clear of stored items
- Ask us about extra access panels where sections can’t be reached
Grease readings are taken again at the same set points, so the report shows the before and after figures. Photos of each section go alongside them.
Watch for warning signs between cleans: grease leaking from duct joints, smells, or a fan that sounds rough. A grease thickness test can confirm whether a spot clean is needed.
