AHU cleaning in Whyteleafe, done properly
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so the report shows exactly what was done. Common call-outs are for dust-coated heating and cooling coils and stale or musty smells from the ventilation, across heating and cooling coils, filter sections and drain trays.
Work in a small place like Whyteleafe starts with agreeing access and timings.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
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.
FAQs for Whyteleafe
Do you do school ventilation cleaning in Whyteleafe in the summer holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 14 schools, colleges and universities with registered kitchens within about a mile and a half of Whyteleafe. Booking early in the term gives the best choice of holiday dates.
Do you work at weekends in Whyteleafe?
Yes, nights and weekends are routine for us. The work in Whyteleafe can fit around your hours. Just call 0345 646 2711, or email photos with your opening times and we’ll plan around them.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
Can you quote from pictures?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and the report recommends a next date.
Are you insured?
Yes. Full insurance covers our work and have been trading since 2009.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. We typically quote within one working day, and emergencies are covered by our 24/7 line.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
How it works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, clear away and hand over the paperwork. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. A quick note on how to find the site and where to park makes a visit to Whyteleafe run smoothly.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
- Arrange a key holder or contact on site
- Let us know about permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Ask for a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
Signs you need AHU cleaning in Whyteleafe
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Most sites get in touch after spotting something like this:
- Coils clogged with dust and debris
- Intake sections clogged with outdoor debris
- Dirty fans and fan housings
- Air handling units due a clean after building work
Classrooms and halls at schools such as Whyteleafe Primary School are easiest to work in when pupils are away.
What your quote should include
- What insurance they carry
- How VAT is shown on the quote
- What records you will receive afterwards
- Proof of accreditation you can verify
What the work involves, part by part
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with pictures so repairs can be planned.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.

What affects the cost of AHU cleaning
There’s no set price list, because sites vary so much. The quote depends on:
- The size of the system
- How easy every part is to reach
- What state the system is in
- Parking and loading at the site
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711, or send details by email, and we’ll explain what it covers.
What we need to know
There’s no need for technical detail. It helps if you can send:
- The times we could work without disrupting the site
- Photos showing the whole system and its surroundings
- Any previous report or certificate
- Close-ups of filters, grilles, hatches or access panels
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
Leave it or put it right?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, ready to show anyone who asks. It’s simpler to plan the work at Whyteleafe now than to arrange it in a hurry later.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.
