How we handle AHU cleaning in New Charlton
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with pictures, so you can see the unit’s condition for yourself. The work covers filter sections, internal panels and dampers and louvres, and people most often call us about leaves and litter drawn into the unit and blocked condensate drains and slimy trays.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in New Charlton.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What affects the cost of AHU cleaning
A fixed price needs a few facts first. We look at:
- Whether several sites go on one quote
- Travel, parking and unloading
- Whether it’s a one-off visit or part of a schedule
- The times the site is available
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before we start.
Asking for a quote
What to send for a quote:
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
- A few general shots of the system
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before we start.
For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
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.
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Flag stale or damp smells in the supply air
- Keep the area around the fresh air intake clear
- Note any water around the unit or leaks below it
- Keep filter changes on time and recorded
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
What AHU cleaning cannot fix
A few issues sit outside what this work can do:
- Building management system faults
- Leaking heating or cooling coils
- The supply and extract ducts, quoted separately
If you’re not sure, just phone us on 0345 646 2711 or email us and we will give you a straight answer.

Your questions about AHU cleaning in New Charlton
Can you work in New Charlton outside opening hours?
Yes, evening, overnight and weekend work is normal for us. That way a site in New Charlton doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Is parking a problem for work in New Charlton?
Tell us where a van can stop near your site in New Charlton, and about any building rules on loading. If the building has a loading slot system, we will book into it.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What about areas you can’t get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and the report recommends a next date.
Why deal with it now?
Standing water in a drain tray does not clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. A building in New Charlton may have flats or offices above and alongside, and a fault in the system can affect them too.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before any work starts.

The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins.

For a job in New Charlton, tell us about loading bays, permits, lifts and roof access when you book.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
