How we price AHU cleaning
Your quote is based on your site. We consider:
- How easy every part is to reach
- What state the system is in
- The times the site is available
- Parking and loading at the site
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 work begins.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- The postcode and the type of business
- When the site is open and when it’s quiet
- Photos showing the whole system and its surroundings
- Problems your staff have spotted
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To start, ring 0345 646 2711, or email photos.
AHU cleaning for kitchens and businesses in Radnage
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. If you have drain trays holding standing water and filters that are clogged or overdue, we can put it right, from drain trays, supply and extract fans and filter sections onwards.
In a village or hamlet like Radnage, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What we do, step by step
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Rural roads and tight entrances are worth telling us about before a visit to Radnage.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Let us know about parking and loading
- Let us know when the site is closed or quiet
- Let us know about permits to work or site inductions

When to call us in Radnage
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that’s the air they breathe for hours on end.
If you notice any of these, it’s worth a diagnosis:
- Intake sections clogged with outdoor debris
- Odours coming through the supply air
- Filters that are clogged or overdue
- Air handling units due a clean after building work
Wherever a school like Radnage Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Questions to ask before you book
- Whether the price is fixed
- When they can work, and whether that’s outside your opening hours
- How they set the interval to the next visit
- Exactly which parts of the system are covered
Your questions about AHU cleaning in Radnage
Is AHU cleaning available in Radnage?
Yes, we work in Radnage and the places around it. You can ring 0345 646 2711, or send details by email and let us know what needs doing.
Can you come to Radnage after we close?
Yes. We work evenings, overnight and at weekends. That way a site in Radnage does not have to lose a day’s trading. Let us know the hours you’re closed and we’ll book within them.
How far ahead should we book?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
How long does it take to clean an air handling unit?
As a guide, it takes half a day to a full day per unit, with large plant planned over several shifts. The shutdown is planned to fit, including evenings or weekends.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after pictures. Keep them in the maintenance log.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.
What do you need from me for a quote?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply phone us on 0345 646 2711, or send details by email.
For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Keep filter changes on time and recorded
- Plan the next inspection before the last report gets filed away
- Check the drain tray is emptying during routine visits
- Make sure the unit’s access doors open easily
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
