West Barnes buildings and their air
There are about 31 schools, colleges and universities and about 55 hospitals, care homes and childcare premises on the FSA’s food hygiene register across West Barnes and its immediate surroundings (about a mile and a half). Where buildings like these have air handling units, filters, coils and drain trays need regular attention. For West Barnes, the closest hospital is Atkinson Morley Hospital, roughly 1.2 miles north. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. London plant rooms are often on roofs or in basements reached through occupied floors.
Hospitals such as Atkinson Morley Hospital (about 1.2 miles north) show how much a building can rely on clean ventilation, and smaller healthcare sites near West Barnes are no different. School buildings such as Sacred Heart Catholic Primary School are usually done in the holidays, so classrooms are not disturbed. For workplaces around Motspur Park station with mechanical ventilation, cleaning can be done in the evening or at weekends.

About our AHU cleaning in West Barnes
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers drain trays, filter sections and internal panels, and the jobs we see most are odours coming through the supply air and blocked condensate drains and slimy trays.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. In West Barnes, as elsewhere, cleaning starts with an inspection of what’s there.
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. Any parts we couldn’t reach are recorded on it too.

In-house cleaning or a specialist?
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
The process
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Before any visit in West Barnes, we agree where the van can stop and how equipment reaches the system.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Name a contact who can let us in at the agreed time
- Mention any parking or loading restrictions
Ask for a quote
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before we start.

The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before any work starts, so there are no surprises.

Managing agents and facilities teams in West Barnes
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.

How we price AHU cleaning
Your quote is based on your site. We consider:
- A single visit or a regular plan
- The scale of the work
- The times the site is available
- What state the system is in
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.
What we need to know
Many jobs can be priced from photos and some basics. Useful things to send:
- Any access panels or hatches you can see
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your last certificate, test record or report
- Wide photos of the system and the area around it
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Between visits
A little care between visits keeps the system in better shape. Our advice:
- Keep filter changes on time and recorded
- Make sure the unit’s access doors open easily
- File each AHU report in the maintenance log
- Plan the next inspection before the last report gets filed away
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
