AHU cleaning for kitchens and businesses in Alverstoke
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. The work covers drain trays, internal panels and dampers and louvres, and people most often call us about rooms that smell stuffy when the system runs and leaves and litter drawn into the unit.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

FAQs for Alverstoke
Can you work in Alverstoke outside opening hours?
Yes, we can come after you close and finish before you open. The work in Alverstoke 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.
Will you come out to Alverstoke?
Yes, we work in villages as well as towns, and Alverstoke is covered. Let us know about access, parking and anything unusual about getting there when you book.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Are you insured?
Yes. Full insurance covers our work and have been trading since 2009.
How long does an AHU clean take?
Typically the clean takes a single shift for a typical unit, longer for large or heavily soiled ones. We plan the shutdown around that, out of hours if needed.
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. After that, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Pictures of the system and its access let us plan the work in Alverstoke before we set off.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Tell us where we can park and unload
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand

Advice
Alverstoke buildings and their air
Food Standards Agency records list about 20 schools, colleges and universities, about 28 caring premises (care homes, nurseries and hospitals) and about 3 hotels and guest houses registered as food businesses within about 1.5 miles of central Alverstoke. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Gosport War Memorial Hospital is the nearest hospital, about 0.9 miles north of Alverstoke. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Gosport War Memorial Hospital, about 0.9 miles north, is the nearest hospital to Alverstoke, and healthcare sites of every size need their supply air kept clean.
Alverstoke is about 2 miles south of Gosport, in Hampshire. Sites in Alverstoke get the same service as everywhere we cover: a survey first, a fixed quote, work timed around your hours and a report with pictures. Across Hampshire, we cover 683 places, and Alverstoke is one of them.

Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Change filters on schedule and log each change
- Keep the area around the fresh air intake clear
- Make sure the unit’s access doors open easily
- File each AHU report in the maintenance log
Stick to the filter change schedule, 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.

Do you need AHU cleaning in Alverstoke?
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Alverstoke, that’s air they breathe for hours at a time.
The symptoms we’re asked about most are:
- Rooms that smell stuffy when the system runs
- Filters that are clogged or overdue
- Condensate trays that will not empty
- Air handling units never cleaned inside
Classrooms and halls at schools such as Alverstoke Community Infant School are easiest to work in when pupils are away.
Questions to ask before you book
- How they set the interval to the next visit
- If they look at the system before pricing
- When they can work, and whether that is outside your opening hours
- How areas they cannot reach will be recorded
What the work involves, part by part
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
Why it’s worth doing now in Alverstoke
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. It also means the next inspection has less to find. If the system at a site near Alverstoke fails, there may be nowhere nearby to move to.
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or drop us a line, and we’ll talk you through it.

Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
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, next to our reports.
Managing agents and facilities teams in Alverstoke
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
