AHU cleaning for kitchens and businesses in Bassett Green
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from pictures or on site, followed by a fixed quote before any cleaning starts. We’re often asked to deal with intake sections clogged with outdoor debris and dirty filters cutting the airflow, across heating and cooling coils, filter sections and supply and extract fans.
Visits to a place like Bassett Green are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Aftercare tips
Simple habits between visits make a real difference. We recommend:
- Don’t ignore odours coming through the grilles
- Keep the area around the fresh air intake clear
- Keep the certificate and photo report with the plant records
- Look at the condensate drain whenever the unit is serviced
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.

For landlords and multi-site operators
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
Bassett Green questions
Can a school’s ventilation in Bassett Green be done out of term time?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 28 schools and colleges with food registrations within roughly a mile and a half of Bassett Green. Send us your term dates when you phone us on 0345 646 2711 or use the quote form, and we’ll fit the work in.
Do you work at weekends in Bassett Green?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Do you clean the ductwork as well?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can quote for both.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
Do you cover Bassett Green?
Yes. We work in Bassett Green and the rest of Southampton, as part of our work across South East England and London. To book, call us on 0345 646 2711 or drop us a line.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, give us a ring on 0345 646 2711, or email photos and tell us about the site and its opening hours.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We don’t leave it behind.
What we are called out for in Bassett Green
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
The symptoms we’re asked about most include:
- Air handling units due a clean after building work
- Dirty filters cutting the airflow
- Odours coming through the supply air
- Drain trays holding standing water
For schools like Bassett Green Primary School, the holidays are the usual time to inspect and clean ventilation.
Before booking anyone
- Whether VAT is included
- Which accreditations they hold, and whether you can check them
- How areas they can’t reach will be recorded
- Whether the work can be done while the site is closed
What AHU cleaning cannot fix
In fairness, there are a few things this work will not fix:
- Building management system faults
- Airflow problems caused by the system’s design
- Ductwork downstream of the unit, which is a separate clean
If you are not sure, just phone us on 0345 646 2711 or send us an email and we’ll give you a straight answer before booking.

Part by part
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Bassett Green buildings and their air
The FSA’s food hygiene register lists about 28 schools, colleges and universities, about 30 caring premises (care homes, nurseries and hospitals) and about 5 hotels and B&Bs with registered kitchens or food service within 1.5 miles or so of the middle of Bassett Green. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 1.9 miles south of Bassett Green is Royal South Hants Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Royal South Hants Hospital, about 1.9 miles south, is the nearest hospital to Bassett Green, and healthcare sites of every size need their supply air kept clean. If you manage shops or offices close to Swaythling station, a TR19® Air inspection shows whether the ductwork needs cleaning.
