AHU cleaning in Bowes Park
Our AHU cleans for sites in Bowes Park cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. The work covers internal panels, filter sections and heating and cooling coils, and the jobs we see most are intake sections clogged with outdoor debris and odours coming through the supply air.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Bowes Park is often done in the evening or at weekends. Loading and parking are planned with the building first.
Good records are part of the job. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What AHU cleaning looks like in Bowes Park
Going by the FSA’s register, there are about 43 schools, colleges and universities and about 53 hospitals, care homes and childcare premises serving food in Bowes Park and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Bowes Park’s nearest hospital, Greentrees Hospital, is about 0.9 miles north-east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
If you manage offices or shops near Alexandra Palace station, their ventilation can be inspected and cleaned out of hours. Classrooms and halls at schools such as Trinity Primary Academy are easiest to work in when pupils are away.

Managing agents and facilities teams in Bowes Park
We also work for facilities teams across offices, schools and healthcare in Bowes Park and across Greater London. Work can be phased by floor, building or site to keep disruption down.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- File each AHU report in the maintenance log
- Don’t ignore odours coming through the grilles
- Don’t store bins or materials near the intake
- Book the next check in line with the report
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
What we do, step by step
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 it goes on the report too. The visit takes from a few hours for a compact unit to a day or more for a large one. In Bowes Park, as across London, we normally work overnight or at weekends and hand the site back ready to open.
- 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.
Getting ready for the visit
- Clear loose items from the work area
- Mention any parking or loading restrictions
- Make sure equipment near the work can be switched off and left to cool
Ask for a quote
To get a fixed quote, call us on 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
Advice
Different parts, different methods
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
When something else is needed
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Airflow problems caused by the system’s design
- Controls and BMS settings that run the unit
- Ductwork downstream of the unit, which is a separate clean
If in doubt, ring 0345 646 2711, or email photos and we will say what we think before you book.
Parts of the system we cover

What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Bowes Park: your questions answered
Is parking a problem for work in Bowes Park?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we will book into it.
Can you work in Bowes Park outside opening hours?
Yes, we can come after you close and finish before you open. The work in Bowes Park can fit around your hours. Just call 0345 646 2711 or send us an email with your opening times and we will plan around them.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we can’t reach are noted in the report, and new panels can be fitted.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, typically ready within one working day.
Where does the waste go?
We take it away when we go. During the work, it’s contained to keep the area clean.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Can we book visits on a schedule?
Yes, of course. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
Signs you need AHU cleaning in Bowes Park
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
Look out for these warning signs:
- Plant that has been serviced but not cleaned
- Condensate trays that will not empty
- Debris and leaves in the fresh air intake
- Stale or musty smells from the ventilation
Healthcare ventilation, from large hospitals like Greentrees Hospital (about 0.9 miles north-east) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before booking
- How areas they cannot reach will be recorded
- Whether the figure could change on the day
- What paperwork you get at the end
- Proof of accreditation you can verify
