AHU cleaning in Forton, done properly
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. Typical jobs include units that have only ever had filter changes and dirty filters cutting the airflow, across heating and cooling coils, filter sections and drain trays.
For a building near Forton, the visit is planned around how it’s used, and the journey is planned ahead. The method does not change: inspect first, clean, then record what was done.
The sign-off is always in writing: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

AHU cleaning around Forton
The FSA’s food hygiene register lists about 33 schools, colleges and universities, about 44 caring premises (care homes, nurseries and hospitals) and about 7 hotels and guest houses with registered kitchens or food service within roughly a mile and a half of the centre of Forton. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Forton’s nearest hospital, Gosport War Memorial Hospital, is about 0.6 miles south-west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Gosport War Memorial Hospital, about 0.6 miles south-west, is the nearest hospital to Forton, and healthcare sites of every size need their supply air kept clean. If you manage a school such as St Mary's Catholic Primary School, ventilation cleaning is best booked for the holidays.

Your questions about AHU cleaning in Forton
Can ventilation in schools around Forton be cleaned out of term?
Yes, out-of-term visits are normal for schools. Around Forton, the Food Standards Agency lists about 33 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you come to Forton after we close?
Yes, we can come after you close and finish before you open. The work in Forton can fit around your hours. Just ring 0345 646 2711, or send details by email with your opening times and we will plan around them.
What information do you need?
Some photos and a quick description of the system plus the address and your hours. We’ll ask for anything else we need.
What if parts of the system can’t be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
Which accreditations do you hold?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Multi-site and managed buildings
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Fixed quotes for AHU cleaning in Forton
We do not publish a price list, because sites vary so much. The quote depends on:
- The condition we find in the survey
- The number of sites or systems
- Site requirements such as sign-in and permits
- The scale of the work
No two sites are the same, 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
A few details help us quote accurately. With your enquiry, please include:
- The roof, plant room or outside wall the system runs to
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- The site address and the type of premises
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
Staff cleaning versus specialist work
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Forton simpler. Booking ahead lets us plan the trip to Forton at a time that suits you.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. A site near Forton normally has room to park, so the questions are about access to the system and your hours.
- The survey covers the unit, its access and how it can be shut down.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Have your last certificate or report to hand
- Move anything stored near the system
- Let us know about permits to work or site inductions
Getting a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
