About our AHU cleaning in Northbrook
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers heating and cooling coils, drain trays and supply and extract fans, and common reasons people get in touch are odours coming through the supply air and air handling units never cleaned inside.
For a building in or near Northbrook, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Good records are part of the job. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

How the visit works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes half a day to a full day per unit, with large plant planned over several shifts. Visits to a village like Northbrook are booked in advance, at a time that suits whoever runs the site.
- The survey covers the unit, its access and how it can be shut down.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Mention any sign-in, permit or induction we need
- Name a contact who can let us in at the agreed time
- Agree a time when the area can be out of use
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

How we price AHU cleaning
The quote reflects the site in front of us. We take into account:
- Site rules, permits and inductions
- The condition we find in the survey
- One-off work versus a regular cycle
- Access, including roofs, risers and ceiling voids
What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.
What to send for a quote
To help us quote quickly, please include:
- The paperwork from the last visit, if you have it
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
- The postcode and the type of business

Why deal with it now?
Stuffy rooms and stale smells in a building in Northbrook can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. A fault that closes a site in a village like Northbrook affects everyone who depends on it.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.

Signs you need AHU cleaning in Northbrook
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Northbrook, that is air they breathe for hours at a time.
Most sites get in touch after spotting something like this:
- Plant that has been serviced but not cleaned
- Intake sections clogged with outdoor debris
- Dirty coils holding back the airflow
- Dust built up on fan impellers
In Northbrook, we look inside the system before deciding what needs cleaning.
What your quote should include
- If the quote is a fixed price or an estimate
- If they look at the system before pricing
- When they can work, and whether that’s outside your opening hours
- What happens if part of the system can’t be accessed
In-house cleaning or a specialist?
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.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Common questions in Northbrook
Do you work at weekends in Northbrook?
Yes, out-of-hours work is a big part of what we do. The work in Northbrook can fit around your hours. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.
Do you offer AHU cleaning in Northbrook?
Yes, Northbrook is within the area we cover across London and the South East. Just call 0345 646 2711 or email us with a few details of the site.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Can you quote from photos?
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.
Can you set up regular visits?
Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
How much does AHU cleaning cost in Northbrook?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, normally ready within one working day.
What about areas you cannot get to?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
