Oakleigh Park AHU cleaning
AHU cleaning for Oakleigh Park, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Dust built up on fan impellers
- Dirty coils holding back the airflow
- Air handling units never cleaned inside
Part by part
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
About our AHU cleaning in Oakleigh Park
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. If you have fan sections that haven’t been cleaned in years and stale or musty smells from the ventilation, we can help.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Oakleigh Park, dust and debris build up in the units and ductwork over time.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Report musty smells from the vents straight away
- Diary the inspection date recommended in the report
- Report water on the plant room floor
- Make sure condensate is draining away
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Common questions in Oakleigh Park
Can you come to Oakleigh Park after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in Oakleigh Park doesn’t have to lose a day’s trading. When you ring 0345 646 2711 or email us, mention when the site is quiet.
Do you clean school ventilation in Oakleigh Park in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Oakleigh Park, the Food Standards Agency lists about 47 schools and colleges with registered kitchens within a mile and a half or so. You can call us on 0345 646 2711 or send us an email with the dates the site is empty.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
Can you quote from pictures?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
Can you look after several sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What do you clean inside the unit?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Common problems we fix in Oakleigh Park
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Oakleigh Park, that is air they breathe for hours at a time.
Common reasons sites call us are:
- Plant that needs cleaning after a refit
- Units that have only ever had filter changes
- Stale or musty smells from the ventilation
- Debris and leaves in the fresh air intake
If you manage offices or shops near Oakleigh Park station, their ventilation can be inspected and cleaned out of hours.

What affects the cost of AHU cleaning
Your quote is based on your site. We take into account:
- Where the site is and how we reach it
- The times the site is available
- One-off work versus a regular cycle
- Whether we need access equipment or extra panels
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.
What to send for a quote
There’s no need for technical detail. It helps if you can send:
- Your opening hours and when the area is out of use
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
- Photos showing the whole system and its surroundings
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
When something else is needed
AHU cleaning can’t fix everything, and we’d rather say so up front. It doesn’t solve:
- Ventilation that was badly designed in the first place
- Damaged coils beyond cleaning
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can give us a ring on 0345 646 2711 or drop us a line and we’ll tell you honestly.
Where we work
- Filter sections
- Internal panels
- Drain trays
- Dampers and louvres
- Supply and extract fans
- Heating and cooling coils
What we do, step by step
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. A name and number for whoever controls access to the building in Oakleigh Park saves time on the night.
- 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.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Ask for a quote
We don’t publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, call us on 0345 646 2711 or send us an email.
Advice
For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so each one has its own record.
