Kingston Vale questions
What do you need to know about parking in Kingston Vale?
Tell us where a van can stop near your site in Kingston Vale, and about any building rules on loading. Night visits tend to make loading easier on London streets.
Do you do school ventilation cleaning in Kingston Vale in the summer holidays?
Yes, out-of-term visits are normal for schools. With about 16 schools and colleges on the FSA’s register within roughly a mile and a half of Kingston Vale, it pays to plan holiday dates ahead. Just ring 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Can you price the work without visiting?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and we typically come back within one working day. If photos aren’t enough, we will survey first.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and we will quote them together.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
What information do you need?
Some pictures and a quick description of the system plus the address and your hours. If we need more, we will ask.
How we handle AHU cleaning in Kingston Vale
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. If you have fan sections that haven’t been cleaned in years and blocked condensate drains and slimy trays, 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 Kingston Vale, dust and debris build up in the units and ductwork over time.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

What we do, step by step
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes from a few hours for a compact unit to a day or more for a large one. In a London area like Kingston Vale, parking, loading and building access are planned before the day of the work.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Let us know about permits to work or site inductions
- Dig out any earlier paperwork for the system
- Agree a time when the area can be out of use

Looking after it afterwards
Here’s the after-treatment advice, short and simple:

- File each AHU report in the maintenance log
- Plan the next inspection before the last report gets filed away
- Check the drain tray is emptying during routine visits
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.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.

Fixed quotes for AHU cleaning in Kingston Vale
Before we fix a price, we need to know a few things. We check:
- Any permits to work or inductions
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
- One-off work versus a regular cycle
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before we start.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- Any access panels or hatches you can see
- A few general shots of the system
- How we’d reach plant on a roof or in a plant room
- The paperwork from the last visit, if you have it
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Why act early in Kingston Vale
If people in a building in Kingston Vale complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. Every month a London system goes without attention adds to what has to be done later.
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before any work starts.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
