AHU cleaning in Crofton: local notes
Food Standards Agency data includes about 19 schools, colleges and universities, about 28 caring premises (care homes, nurseries and hospitals) and about 3 hotels and B&Bs in and around Crofton, up to about a mile and a half out. 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 3 miles south-east of Crofton. 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 3 miles south-east, is the nearest hospital to Crofton, and healthcare sites of every size need their supply air kept clean. If you manage a school such as Crofton School, ventilation cleaning is best booked for the holidays.

How we handle AHU cleaning in Crofton
Our AHU cleaning covers sites in Crofton and the rest of Hampshire, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you’re dealing with leaves and litter drawn into the unit and rooms that smell stuffy when the system runs, we can help.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Between visits
To keep the system working properly between visits:
- Don’t store bins or materials near the intake
- Report musty smells from the vents right away
- Check the drain tray is emptying during routine visits
- Report stiff or damaged access doors
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.

When it’s something else
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It does not solve:
- Dirty ducts beyond the unit itself
- A system that’s undersized for the building
- Mechanical faults with motors, belts or bearings
If you’re not sure, just give us a ring on 0345 646 2711, or send details by email and we will give you a straight answer.

For landlords and multi-site operators
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, 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.
How the job changes from site to site
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
How it works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes one overnight shift for many single units, with bigger plant phased, and we clear up before we go. If the van will struggle with a lane or gateway near Crofton, let us know and we’ll plan around it.
- 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.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Dig out any earlier paperwork for the system
- Make sure someone can let us in and lock up afterwards

Advice
Questions from Crofton
Can the work in Crofton be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Crofton keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Do you do school ventilation cleaning in Crofton in the summer holidays?
Yes, and it’s the easiest time to do it. With about 19 schools and colleges on the FSA’s register within roughly a mile and a half of Crofton, it pays to plan holiday dates ahead. Send us your term dates when you call 0345 646 2711 or use the quote form, and we’ll fit the work in.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
Do you do ventilation duct cleaning too?
Yes, the ductwork, grilles and diffusers the unit serves. We’ll tell you after the survey whether the ducts need it.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
What should I send you?
A short description and a few pictures, with the address and opening hours. We will ask for anything else we need.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- The times the site is available
- How big the system is
- The condition we find in the survey
- Where the site is and how we reach it
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Detail shots of panels, filters and grilles
- Any previous report or certificate
- Where the plant sits or the system leaves the building, such as a roof or outside wall
