How we price AHU cleaning
The survey tells us what the work involves. We look at:
- The size of the system
- Whether several sites go on one quote
- Site requirements such as sign-in and permits
- Travel, parking and unloading
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.
What to send for a quote
You don’t need the technical terms. It helps if you can send:
- The site address and the type of premises
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
- Any access panels or hatches you can see
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.
AHU cleaning in South Ruislip
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. If you have fan sections that haven’t been cleaned in years and debris and leaves in the fresh air intake, 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 South Ruislip, dust and debris build up in the units and ductwork over time.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

If in doubt, call us on 0345 646 2711, or send details by email and we’ll say what we think before you book.
What the work covers
- Supply and extract fans
- Drain trays
- Heating and cooling coils
- Filter sections
- Dampers and louvres
- Internal panels
Aftercare tips
How long the results last depends on use and care. We suggest:
- Book the next check in line with the report
- Make sure the unit’s access doors open easily
- File each AHU report in the maintenance log
- Keep filter changes on time and recorded
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
South Ruislip: your questions answered
Can you clean school ventilation in South Ruislip during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 30 schools, colleges and universities with registered kitchens within about a mile and a half of South Ruislip. Booking early in the term gives the best choice of holiday dates.
Can the work in South Ruislip be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in South Ruislip needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
How long will the unit be out of action?
Typically the clean takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the shutdown around that, including evenings or weekends.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.

Common problems we fix in South Ruislip
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and that’s where slime and odours start.
These are the problems we see most often:
- Blocked condensate drains and slimy trays
- Leaves and litter drawn into the unit
- Air handling units due a clean after building work
- Air handling units never cleaned inside
Workplaces around South Ruislip station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
Questions to ask before booking
- If the quote is a fixed price or an estimate
- What records you’ll receive afterwards
- Whether the quote shows VAT
- Which accreditations they hold, and whether you can check them
How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. We fit London jobs around the building rather than the other way round, so a visit in South Ruislip is usually out of hours.
- We look at the unit and the plant area during the survey.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use

In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
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.
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building around the people who use them.
