- Plant that needs cleaning after a refit
- Odours coming through the supply air
- Intake sections clogged with outdoor debris
What a clean will not put right
We won’t sell you work that does not address the problem, so these are the things it will not cover:
- Damaged coils beyond cleaning
- Mechanical faults with motors, belts or bearings
- Ventilation that was badly designed in the first place
If in doubt, call us on 0345 646 2711 or email us and we’ll say what we think.
Where we work
- Heating and cooling coils
- Supply and extract fans
- Dampers and louvres
- Internal panels
- Filter sections
- Drain trays
How we handle AHU cleaning in Beaconsfield
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins are not flattened. Common call-outs are for leaves and litter drawn into the unit and dirty coils holding back the airflow, on internal panels, dampers and louvres and heating and cooling coils.
In Beaconsfield, ventilation in schools and offices is cleaned when the building is quiet: out of hours, at weekends or during the holidays.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

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. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s 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.

Fixed quotes for AHU cleaning in Beaconsfield
We quote each job individually. This is what makes a difference:
- Site rules, permits and inductions
- The times the site is available
- The size of the system
- The condition of the system
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before work begins.
Asking for a quote
What to send for a quote:
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
- Your last certificate, test record or report
- A few general shots of the system
Getting a quote doesn’t take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
The process
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. On site, it takes one overnight shift for many single units, with bigger plant phased. Send us pictures of the system and we can plan most of a visit in Beaconsfield before we arrive.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet
- Let us know about permits to work or site inductions
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.
Advice
Between visits
So the system stays in good health:
- Keep the certificate and photo report with the plant records
- Look at the condensate drain whenever the unit is serviced
- Make sure the unit’s access doors open easily
- Plan the next inspection before the last report gets filed away
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
Multi-site and managed buildings
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

Why it’s worth doing now in Beaconsfield
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. Before an inspection or an insurer’s visit in Beaconsfield, it helps to have up-to-date records.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, call 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.
