About our ductwork cleaning in Bitterne
In doctor’s terms, the ductwork is the system’s arteries: find the blockages, clear them, then check the flow is right. Grease readings before and after give you the evidence, alongside before and after photos. The work covers attenuators, vertical risers and access panels, and people most often call us about hardened, baked-on grease in long horizontal runs and a rancid smell from the extract duct.
In a smaller place like Bitterne, many kitchens sit in older buildings or later extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What the work involves, part by part
Horizontal duct runs
A long flat run can’t be cleaned from one end. Any stretch out of reach is noted and can fit extra panels.
Bends and transitions
The join where the canopy meets the duct is a common hotspot. We clean it from the canopy side or through a nearby panel.
Bitterne kitchens: local notes
Sea air reaches Bitterne, which sits within about 2 miles of the coast. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. According to Food Standards Agency records, there are about 50 bars, pubs and nightclubs and about 4 hotels, B&Bs and guest houses across Bitterne and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. It’s Southampton council that sends environmental health officers to food businesses in Bitterne. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
A hospital like Royal South Hants Hospital, about 1.5 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. For schools such as Bitterne CE Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.

What happens if it’s left?
Grease left in a duct in Bitterne hardens over time. It bakes into a hard layer that takes far longer to remove, so the later the clean, the bigger the job. Booking now means the visit to Bitterne is planned around you, not forced by a breakdown.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711 or email us for straight advice and a fixed quote.

What we do, step by step
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 the same goes into the written report. All told, the work takes a few hours for a short run, longer for long runs and tall risers. In a smaller place like Bitterne, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- We map the duct route and check where the access panels are.
- We measure grease thickness at set points before cleaning.
- Through the access panels, thick grease is removed by hand first.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- We test again, take pictures and note any part that couldn’t be reached.
Preparing for the visit
- Move anything stored near the system
- Plan for cooking equipment or plant to be off before we arrive
- Tell us the best time to work, such as after service or at a weekend
How to get a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before we start.
Related advice
What we’re called out for in Bitterne
A vertical riser can run up several floors. Grease clings to the walls and can run down to the base, where it can pool. Access along its height is needed to clean it properly.
Look out for these warning signs:
- Grease leaking from duct joints
- Years of grease along the duct floor
- Smells of old cooking grease from the ductwork
- Ductwork that has never been cleaned
Church and community hall kitchens, near Church of the Holy Saviour or anywhere around Bitterne, are easy to forget, but their extracts collect grease like any other.
Questions to ask before you book
- Whether the work can be done while the site is closed
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

Questions from Bitterne
Which environmental health team covers Bitterne?
The local authority for Bitterne is Southampton council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Which fire service covers Bitterne?
Bitterne is in the area of Hampshire and Isle of Wight Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
When is the ductwork cleaned?
The duct is cleaned out of hours, so evenings, nights and weekends are all possible. Equipment and the extract are switched off while we work.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Is a quote from pictures possible?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and we normally come back within one working day. If photos aren’t enough, we will survey first.
Can you clean ductwork with no access panels?
We clean everything we can reach and record what we cannot. Extra panels can be installed, and we can do that for you.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- Book the next clean before the recommended date
- Report any grease dripping from duct joints
- Keep access panels clear of stored items
- Keep the fan on while anything is cooking
When the duct is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through 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.
When it’s something else
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- A worn-out fan that needs replacing
- Leaking duct joints that need repair
- Duct sealed behind fixed ceilings or walls
If you are not sure, just ring 0345 646 2711 or drop us a line and we will give you a straight answer before you book.
