About our AHU cleaning in Westerham
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. The work covers drain trays, internal panels and supply and extract fans, and people most often call us about filters that are clogged or overdue and units needing a clean before a new tenant or handover.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Westerham.
The paperwork matters as much as the work. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Do you need AHU cleaning in Westerham?
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
Signs it’s time to call us include:
- Leaves and litter drawn into the unit
- Filters that are clogged or overdue
- Units that have only ever had filter changes
- Fan sections that haven’t been cleaned in years
Hospitals such as Tandridge Priory (about 2.2 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Westerham are no different.
Questions to ask before you book
- If the quote is a fixed price or an estimate
- Proof of insurance
- When they can work, and whether that is outside your opening hours
- Whether the whole system is included, or only the parts that are easy to reach
Fixed quotes for AHU cleaning in Westerham
A fixed price needs a few facts first. We look at:
- One-off work versus a regular cycle
- Parking and loading at the site
- How easy every part is to reach
- The times the site is available
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- Any previous report or certificate
- Wide pictures of the system and the area around it
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
For a fixed quote, call us on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You will normally have a quote within one working day.
Aftercare tips
Results last longer with the right care. We suggest:
- Stick to the filter change plan
- Report water on the plant room floor
- Make sure the unit’s access doors open easily
- Report musty smells from the vents right away
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
The process
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Westerham.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- 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.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Tell us where we can park and unload
- Mention any sign-in, permit or induction we need

Related advice
In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Keep a record of what your team does. 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.
