Do you need AHU cleaning in Hither Green?
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Common reasons sites call us are:
- Dirty coils holding back the airflow
- Blocked condensate drains and slimy trays
- Debris and leaves in the fresh air intake
- Units that have only ever had filter changes
For schools like Brindishe Manor School, the holidays are the usual time to inspect and clean ventilation.

AHU cleaning in Hither Green
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. We are often asked to deal with units that have only ever had filter changes and rooms that smell stuffy when the system runs, on dampers and louvres, heating and cooling coils and filter sections.
London buildings tend to keep their plant on the roof or below ground, so work in Hither Green is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Aftercare tips
After the visit, a few habits help the work last:
- Keep the certificate and photo report with the plant records
- Change filters on schedule and log each change
- Clear leaves and litter away from the intake
- Note any water around the unit or leaks below it
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
What affects the cost of AHU cleaning
The survey tells us what the work involves. The main factors are:
- Whether it’s a one-off visit or part of a schedule
- Working hours and out-of-hours timing
- The number of sites or systems
- Access, including roofs, risers and ceiling voids
The cost depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.
Asking for a quote
What to send for a quote:
- The times we could work without disrupting the site
- Any previous report or certificate
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide pictures of the system and the area around it
If you need AHU cleaning in Hither Green, call 0345 646 2711, or email photos. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. We normally send a fixed quote within one working day.

What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Planning ahead in Hither Green lets you pick a quiet night rather than lose a busy one.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What you get with us

Your questions about AHU cleaning in Hither Green
How do you handle parking and loading in Hither Green?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
Do you clean school ventilation in Hither Green in the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 38 schools, colleges and universities with registered kitchens within about a mile and a half of Hither Green. Send us your term dates when you call us on 0345 646 2711, or email photos, and we’ll fit the work in.
Do you survey before quoting?
Yes. We always survey first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
Can you clean the AHU out of hours?
Yes. We time the work to fit the building’s hours. Healthcare and care settings are planned with staff.
Can you clean the ducts connected to the AHU?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Is Hither Green in your area?
Yes. Hither Green is part of the area we cover, as part of our area across London and the South East.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes half a day to a full day per unit, with large plant planned over several shifts. Most London sites can’t stop for the day, so work in Hither Green is usually done overnight, early in the morning or at weekends.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Tell us where we can park and unload
- Plan for cooking equipment or plant to be off before we arrive
- Name a contact who can let us in at the agreed time
How to get a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
