FAQs for Gosport
Can the work in Gosport be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The work in Gosport can fit around your hours. When you call 0345 646 2711 or send us an email, mention when the site is quiet.
Do you clean school ventilation in Gosport in the holidays?
Yes. The holidays are the usual time for school work. Around Gosport, the Food Standards Agency lists about 33 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you call us on 0345 646 2711, or email photos, and we will fit the work in.
How much does AHU cleaning cost in Gosport?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, usually ready within one working day.
What about areas you can’t get to?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
Will the ventilation be off while you clean?
Yes, for the time we’re working on it. We can work evenings, overnight or at weekends to keep disruption down.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you have a 24/7 line?
Yes. 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.
How long will the unit be out of action?
Typically the clean takes from a few hours for a compact unit to a day or more for a large one. The shutdown is planned to fit, out of hours if needed.
AHU cleaning for kitchens and businesses in Gosport
Where a building in Gosport has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. The work covers heating and cooling coils, filter sections and drain trays, and the jobs we see most are odours coming through the supply air and units needing a clean before a new tenant or handover.
In Gosport, ventilation in schools and offices is cleaned when the building is quiet: out of hours, at weekends or during the holidays.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What affects the quote in Gosport
We quote each job individually. This is what makes a difference:
- What state the system is in
- Travel, parking and unloading
- The number of sites or systems
- How big the system is
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
Helping us quote
You don’t need the technical terms. Just send:
- The postcode and the type of business
- The times we could work without disrupting the site
- How we’d reach plant on a roof or in a plant room
- Detail shots of panels, filters and grilles
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.
How it works
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. From there, it takes one overnight shift for many single units, with bigger plant phased. Let us know how to reach the roof or plant area at your site in Gosport, and where the van can go.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Dig out any earlier paperwork for the system
- Tell us where we can park and unload
Ask for a quote
Getting a quote does not take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Gosport buildings and their air
The FSA’s food hygiene register lists about 33 schools, colleges and universities, about 40 care, childcare and hospital premises and about 3 hotels and guest houses with registered kitchens or food service in Gosport and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Gosport’s nearest hospital, Gosport War Memorial Hospital, is about 0.8 miles south. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
For schools like Brockhurst Primary School, the holidays are the usual time to inspect and clean ventilation.

Nearby you’ll also find Search (1.3 miles south-east) and Gosport War Memorial Hospital (0.8 miles south). Open spaces near Gosport include Portsdown Hill and West of the River Alver.
Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Watch for drips or damp patches near the plant
- Change filters on schedule and log each change
- Diary the inspection date recommended in the report
- Keep the certificate and photo report with the plant records
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
Why it’s worth doing now in Gosport
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. If an inspection, an insurer’s survey or a fire risk assessment is coming up in Gosport, having the work done and recorded first helps.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before work begins.

Common problems we fix in Gosport
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
These are the problems we see most often:
- Units that have only ever had filter changes
- Dirty coils holding back the airflow
- Leaves and litter drawn into the unit
- Dirty filters cutting the airflow
If you run a surgery, dental practice or care home near Gosport, clean ventilation matters as much to you as to a hospital like Gosport War Memorial Hospital (about 0.8 miles south).

Part by part
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
