What AHU cleaning cannot fix
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It won’t put right:
- Mechanical faults with motors, belts or bearings
- Dirty ducts beyond the unit itself
- Leaking heating or cooling coils
If in doubt, call us on 0345 646 2711 or email us and we will say what we think.
Where we work
- Dampers and louvres

AHU cleaning in Bandonhill
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and give you a fixed quote, so you know where you stand. Common call-outs are for dirty filters cutting the airflow and blocked condensate drains and slimy trays, on supply and extract fans, heating and cooling coils and internal panels.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in Bandonhill.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Larger estates can be phased building by building to keep disruption down.
Bandonhill: your questions answered
Do you work at weekends in Bandonhill?
Yes, out-of-hours work is a big part of what we do. That way a site in Bandonhill does not have to lose a day’s trading. When you ring 0345 646 2711, or email photos, mention when the site is quiet.
Can ventilation in schools around Bandonhill be cleaned out of term?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 37 schools, colleges and universities with registered kitchens within about a mile and a half of Bandonhill. Booking early in the term gives the best choice of holiday dates.
Do you look at the system first?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. A fixed quote follows.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Is a quote from pictures possible?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. At the end, the area is cleaned down.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
What if parts of the system can’t be reached?
Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
How we price AHU cleaning
The diagnosis comes before the price. We look at:
- How big the system is
- Site rules, permits and inductions
- How easy every part is to reach
- What state the system is in
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
What to send for a quote
To help us quote quickly, please include:
- Detail shots of panels, filters and grilles
- A few general shots of the system
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, call us on 0345 646 2711 or drop us a line.

What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Bandonhill.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Dig out any earlier paperwork for the system
- Make sure someone can let us in and lock up afterwards
- Make sure equipment near the work can be switched off and left to cool
Get a fixed quote
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 work begins.
Advice
When to call us in Bandonhill
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
These are the problems we see most often:
- Plant that needs cleaning after a refit
- Dirty coils holding back the airflow
- Units that have only ever had filter changes
- Fan sections that haven’t been cleaned in years
Hospitals such as Purley War Memorial Hospital (about 1.8 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Bandonhill are no different.
Comparing quotes
- How they set the interval to the next visit
- If the quote is a fixed price or an estimate
- Exactly which parts of the system are covered
- When they can work, and whether that’s outside your opening hours
What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
How the job changes from site to site
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Ventilation in Bandonhill buildings
Food Standards Agency data includes about 37 schools, colleges and universities, about 75 caring premises (care homes, nurseries and hospitals) and about 5 hotels and guest houses across Bandonhill and its immediate surroundings (about a mile and a half). Busy, occupied buildings like these are where clean supply air matters most. The nearest hospital to Bandonhill is Purley War Memorial Hospital, about 1.8 miles south-east. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Ventilation cleaning in London buildings is normally planned for evenings or weekends.
Workplaces around Waddon station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. Classrooms and halls at schools such as High View Primary School are easiest to work in when pupils are away.
