What the work involves, part by part
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
AHU cleaning for kitchens and businesses in Stratford St Mary
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. Typical jobs include intake sections clogged with outdoor debris and dirty filters cutting the airflow, on supply and extract fans, drain trays and dampers and louvres.
In a village or hamlet like Stratford St Mary, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What else we do in Stratford St Mary
What happens on the day
When we arrive, we check the system against the survey or the pictures you sent. 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. Somewhere as small as Stratford St Mary, the date and timings are agreed with you well before the day.
- First we agree when the unit can be switched off, including evenings or weekends.
- 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.
- After pictures are taken and the certificate issued.

Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Honest limits
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It doesn’t solve:
- Dirty ducts beyond the unit itself
- Problems with the unit’s controls or sensors
- A system that’s undersized for the building
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we’ll tell you honestly.

What affects the quote in Stratford St Mary
You’ll get a fixed price before work begins. It’s based on:
- Site requirements such as sign-in and permits
- The times the site is available
- Whether it’s a one-off visit or part of a schedule
- The condition of the system
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.
Asking for a quote
To help us quote quickly, send us:
- Your last certificate, test record or report
- The site address and the type of premises
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.
Between visits
Aftercare is simple, and it helps at the next visit:
- Watch for drips or damp patches near the plant
- Change filters on schedule and log each change
- Plan the next inspection before the last report gets filed away
- File each AHU report in the maintenance log
When we have closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
