In-house cleaning or a specialist?
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
AHU cleaning in Latimer
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. The work covers filter sections, supply and extract fans and dampers and louvres, and common reasons people get in touch are plant that has been serviced but not cleaned and leaves and litter drawn into the unit.
Work in a small place like Latimer starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Signs you need AHU cleaning in Latimer
Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Any of these means the system needs a check-up:
- Plant that has been serviced but not cleaned
- Fan sections that haven’t been cleaned in years
- Dust-coated heating and cooling coils
- Dirty filters cutting the airflow
If you run a surgery, dental practice or care home near Latimer, clean ventilation matters as much to you as to a hospital like Amersham Hospital (about 3.1 miles south-west).

We take it away when we go. During the work, it’s contained so the area stays clean.

We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
What should I send you?
A short description and a few photos plus the address and your hours. We will ask for anything else we need.

What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The scale of the work
- The number of sites or systems
- Parking and loading at the site
- Whether it’s a one-off visit or part of a schedule
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or drop us a line, and we will explain what it covers.
Asking for a quote
When you contact us, these details help:
- The roof, plant room or outside wall the system runs to
- Wide photos of the system and the area around it
- Detail shots of panels, filters and grilles
- The postcode and the type of business
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, before work begins.
What happens on the day
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes one overnight shift for many single units, with bigger plant phased. We agree a date with you, plan the drive to Latimer and turn up when the site is quiet.
- 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.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Name a contact who can let us in at the agreed time
- Let us know about permits to work or site inductions
- Plan for cooking equipment or plant to be off before we arrive

Advice
Different parts, different methods
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
