About our AHU cleaning in Alfold Crossways
We clean air handling units for buildings in Alfold Crossways and across Surrey, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers supply and extract fans, dampers and louvres and internal panels, and common reasons people get in touch are dirty filters cutting the airflow and dust built up on fan impellers.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Fixed quotes for AHU cleaning in Alfold Crossways
We quote each job individually. These are the things that affect it:
- What state the system is in
- Site rules, permits and inductions
- How easy every part is to reach
- How big the system is
What you pay depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.
Helping us quote
To help us quote quickly, send us:
- Wide photos of the system and the area around it
- Your last certificate, test record or report
- The roof, plant room or outside wall the system runs to
- Where the site is and what kind of site it is
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.
How it works
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the AHU cleaning, clear away and hand over the paperwork. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. The timing of a visit to Alfold Crossways is set by you, and the travel is our side of the planning.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Make sure equipment near the work can be switched off and left to cool
- Find the previous report, if there is one

Advice
Part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
When to call us in Alfold Crossways
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. So a unit can be well maintained and still dirty.
Any of these means the system needs a check-up:
- Plant that needs cleaning after a refit
- Fan sections that haven’t been cleaned in years
- Filters that are clogged or overdue
- Stale or musty smells from the ventilation
An inspection comes first for any ventilation job around Alfold Crossways, so the cleaning matches what’s there.

Your questions about AHU cleaning in Alfold Crossways
Is Alfold Crossways within the area you cover?
Yes, Alfold Crossways is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Do you work overnight in Alfold Crossways?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Alfold Crossways needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Is a quote from photos possible?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after pictures. Keep them in the maintenance log.
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. Then phone us on 0345 646 2711, or send details by email.
How often should an air handling unit be cleaned?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
What happens to the waste?
We take it away at the end of the visit. During the work, it’s contained to keep the area clean.
How much does AHU cleaning cost in Alfold Crossways?
Every site is different, so each gets its own fixed quote. To get one, give us a ring on 0345 646 2711 or drop us a line with the site type, opening hours and a few photos.

Why deal with it now?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. In a small place like Alfold Crossways, a system that fails can take a site out of use.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.

For landlords and multi-site operators
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. With shared responsibility, good records help everyone.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
