AHU cleaning in Holmethorpe
We clean air handling units for buildings in Holmethorpe and across Surrey, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers supply and extract fans, internal panels and dampers and louvres, and people most often call us about units that have only ever had filter changes and dirty coils holding back the airflow.
Around a place like Holmethorpe, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
A written report with pictures follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What we do, step by step
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes half a day to a full day per unit, with large plant planned over several shifts. For a place like Holmethorpe, we load the van from the survey notes so the work can be done in one visit where possible.
- 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
- Make sure someone can let us in and lock up afterwards
- Tell us about site rules, permits or sign-in
- Clear loose items from the work area
How to get a quote
Photos are enough for some jobs, while others need a look on site. 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.

What staff can safely do
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The number of sites or systems
- Site requirements such as sign-in and permits
- What state the system is in
- Whether we need access equipment or extra panels
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 will get one fixed quote.
What we need to know
What to send for a quote:
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
For AHU cleaning in Holmethorpe, call us on 0345 646 2711 or use the quote form. Tell us what kind of premises it is and when it’s open, and send photos or your last report if you can. A fixed quote normally follows within one working day.
Why act early in Holmethorpe
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Booking ahead lets us plan the trip to Holmethorpe at a time that suits you.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.

Signs you need AHU cleaning in Holmethorpe
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Most sites get in touch after spotting one of these:
- Condensate trays that won’t empty
- Intake sections clogged with outdoor debris
- Rooms that smell stuffy when the system runs
- Fan sections that haven’t been cleaned in years
School buildings such as East Surrey College are normally done in the holidays, so classrooms aren’t disturbed.
Before booking anyone

- How VAT is shown on the quote
- What records you’ll receive afterwards
- Whether the whole system is included, or only the parts that are easy to reach
Holmethorpe: your questions answered
Can a school’s ventilation in Holmethorpe be done out of term time?
Yes. The holidays are the usual time for school work. With about 10 schools and colleges on the FSA’s register within roughly a mile and a half of Holmethorpe, it pays to plan holiday dates ahead. Just give us a ring on 0345 646 2711 or email us with your term dates and we’ll plan around them.
Can you come to Holmethorpe after we close?
Yes, out-of-hours work is a big part of what we do. It means the site in Holmethorpe keeps running as normal. Your opening times are the first thing we ask for.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What do you need from me for a quote?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply call us on 0345 646 2711 or send us an email.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
When it’s something else
A few issues sit outside what this work can do:
- Leaking heating or cooling coils
- Building management system faults
- A system that’s undersized for the building
If you are not sure, just give us a ring on 0345 646 2711 or drop us a line and we will give you a straight answer before booking.
