About our AHU cleaning in South Norwood
Our AHU cleaning covers sites in South Norwood and the rest of Greater London, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you have intake sections clogged with outdoor debris and coils clogged with dust and debris, we can put it right, from filter sections, internal panels and dampers and louvres onwards.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in South Norwood is usually planned out of hours. Parking and loading are agreed with the building in advance.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Multi-site and managed buildings
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Why deal with it now?
If people in a building in South Norwood complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. It’s better booked as a planned job in South Norwood than handled as an emergency.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.

When it’s something else
To be straight with you, some problems need a different fix:
- Leaking heating or cooling coils
- Building management system faults
- Breakdowns that need a mechanical engineer
Not sure which it is? You can call us on 0345 646 2711 or email us and we’ll tell you honestly before booking.
Parts of the system we cover
- Heating and cooling coils
- Internal panels
- Supply and extract fans
- Filter sections
- Dampers and louvres
- Drain trays
How the job changes from site to site
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
What affects the cost of AHU cleaning
We quote each job individually. These are the things that affect it:
- Whether several sites go on one quote
- The scale of the work
- Working hours and out-of-hours timing
- One-off work versus a regular cycle
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before work begins.
Asking for a quote
We can often survey from pictures. The most useful are:
- The paperwork from the last visit, if you have it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- When the site is open and when it’s quiet
- Where the site is and what kind of site it is
To help us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Once you have those, call 0345 646 2711 or use the quote form.
South Norwood: your questions answered
Do you clean school ventilation in South Norwood in the holidays?
Yes, and it’s the easiest time to do it. With about 36 schools and colleges on the FSA’s register within roughly a mile and a half of South Norwood, it pays to plan holiday dates ahead. You can give us a ring on 0345 646 2711, or send details by email with the dates the site is empty.
Can the work in South Norwood be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The work in South Norwood can fit around your hours. Just call 0345 646 2711 or email us with your opening times and we’ll plan around them.
Do you repair air handling units?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Is there a report after cleaning?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
Is a quote from pictures possible?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
How long does an AHU clean take?
It takes a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, which takes a single shift for a typical unit, longer for large or heavily soiled ones. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in South Norwood.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool

What else we do in South Norwood
Do you need AHU cleaning in South Norwood?
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
These are the problems we see most often:
- Dirty filters cutting the airflow
- Plant that has been serviced but not cleaned
- Leaves and litter drawn into the unit
- Dust-coated heating and cooling coils
School buildings such as St Mark's Church of England Primary Academy are normally done in the holidays, so classrooms are not disturbed.
