What affects the cost of AHU cleaning
There’s no set price list, because no two systems are the same. What we look at:
- Site rules, permits and inductions
- Access, including roofs, risers and ceiling voids
- The times the site is available
- One-off work versus a regular cycle
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.
Asking for a quote
There’s no need for technical detail. Just send:
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
- When the site is open and when it’s quiet
- Wide pictures of the system and the area around it
Getting a quote does not take long. Call or email with a few details and you will typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
AHU cleaning in Brook
An air handling unit is the heart of a building’s ventilation: 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, which is why we clean the unit itself, not just the ducts. If you’re dealing with dirty coils holding back the airflow and dirty fans and fan housings, we can put it right.
In a village or hamlet like Brook, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Brook: your questions answered
Will you come out to Brook?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Do you cover Brook for AHU cleaning?
Yes, Brook is within the area we cover across London and the South East. To start, call 0345 646 2711, or send details by email with a few pictures of the system.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Do you need to switch the unit off?
Yes, for the time we’re working on it. Out-of-hours work is available so the building isn’t left without ventilation when it’s busy.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
What a clean will not put right
AHU cleaning can’t fix everything, and we’ll tell you before work begins. It will not put right:
- Building management system faults
- Ductwork downstream of the unit, which is a separate clean
- Faulty motors, drives or bearings
Not sure which it is? You can phone us on 0345 646 2711, or send details by email and we’ll tell you honestly.

Landlords, agents and facilities managers
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
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.
How the visit works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes one overnight shift for many single units, with bigger plant phased, and we clear up before we go. Seeing the system in pictures first means the trip to Brook can be planned properly.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Mention any sign-in, permit or induction we need
- Clear the space around the work
- Make sure someone can let us in and lock up afterwards

When to call us in Brook
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Look out for these warning signs:
- Filters that are clogged or overdue
- Fan sections that haven’t been cleaned in years
- Air handling units due a clean after building work
- Stale or musty smells from the ventilation
An inspection comes first for any ventilation job around Brook, so the cleaning matches what’s there.

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Make sure condensate is draining away
- Flag stale or damp smells in the supply air
- Clear leaves and litter away from the intake
- 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. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
