What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
About our AHU cleaning in Streatham Hill
Our AHU cleaning covers sites in Streatham Hill 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. The work covers internal panels, supply and extract fans and heating and cooling coils, and the jobs we see most are debris and leaves in the fresh air intake and units that have only ever had filter changes.
London buildings tend to keep their plant on the roof or below ground, so work in Streatham Hill is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
The paperwork matters as much as the work. Each visit is written up with pictures, 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 ready for an insurer, fire officer or EHO.

What else we do in Streatham Hill
Aftercare tips
After the visit, a few habits help the work last:
- Book the next check in line with the report
- Keep filter changes on time and recorded
- Make sure the unit’s access doors open easily
- Flag stale or damp smells in the supply air
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Leave it or put it right?
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. A building in Streatham Hill may have flats or offices above and alongside, and a fault in the system can affect them too.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before we start.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
When to call us in Streatham Hill
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 some travels further into the unit.
If you notice any of these, it’s worth a diagnosis:
- Air handling units with blocked filters
- Units that have only ever had filter changes
- Odours coming through the supply air
- Leaves and litter drawn into the unit
Hospitals such as Tooting Bec Hospital (about 1.4 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Streatham Hill are no different.

Your questions about AHU cleaning in Streatham Hill
Can parking be tricky for a job in Streatham Hill?
A loading bay, a visitor permit or off-street space near the site in Streatham Hill makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
Do you clean school ventilation in Streatham Hill in the holidays?
Yes. The holidays are the usual time for school work. There are about 49 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Streatham Hill. Booking early in the term gives the best choice of holiday dates.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and the report recommends a next date.
What should I send you?
A short description and a few pictures plus the address and your hours. If we need more, we’ll ask.
How do you protect the area?
Floors and surfaces near the work are sheeted before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
Do you have insurance?
Yes. Full insurance covers our work and have been trading since 2009.
Do you work in Streatham Hill?
Yes. Our technicians work in Streatham Hill, as part of our area across London and the South East.
What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes from a few hours for a compact unit to a day or more for a large one. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Streatham Hill.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
How to prepare
- Find the previous report, if there is one
- Tell us where we can park and unload
- Tell us the best time to work, such as after service or at a weekend
Ask for a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

Part by part
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
