AHU Cleaning in White Waltham
Professional AHU cleaning in and around White Waltham, timed so the site keeps working and signed off in writing with photos.
- Drain trays holding standing water
- Dust-coated heating and cooling coils
- Units needing a clean before a new tenant or handover
Multi-site and managed buildings
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
About our AHU cleaning in White Waltham
Our AHU cleans for sites in White Waltham cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers drain trays, dampers and louvres and heating and cooling coils, and people most often call us about air handling units never cleaned inside and filters that are clogged or overdue.
In a village or hamlet like White Waltham, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How the visit works
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere like White Waltham, lanes, gates and parking are worth mentioning in advance.
- We survey the unit from photos or on site and agree what’s included.
- 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.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Arrange a key holder or contact on site
- Mention any parking or loading restrictions
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

How the job changes from site to site
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Signs you need AHU cleaning in White Waltham
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
If you notice any of these, it’s worth a diagnosis:
- Leaves and litter drawn into the unit
- Fan sections that haven’t been cleaned in years
- Blocked condensate drains and slimy trays
- Air handling units never cleaned inside
If you manage a school such as White Waltham CofE Academy, ventilation cleaning is best booked for the holidays.
What to look for in a quote
- What paperwork you get at the end
- Whether a survey comes first
- Whether the price is fixed
- Whether the whole system is included, or only the parts that are easy to reach
What a clean won’t put right
Some problems need a different service or another trade:
- Controls and BMS settings that run the unit
- Mechanical faults with motors, belts or bearings
- Dirty ducts beyond the unit itself
If you’re not sure, just call us on 0345 646 2711, or email photos and we will give you a straight answer.
What the work covers
- Supply and extract fans
- Drain trays
- Heating and cooling coils
- Internal panels
- Filter sections
- Dampers and louvres

What else we do in White Waltham
White Waltham: your questions answered
Can you work in White Waltham outside opening hours?
Yes, out-of-hours work is a big part of what we do. It means the site in White Waltham keeps running as normal. Just give us a ring on 0345 646 2711, or email photos with your opening times and we’ll plan around them.
Will you come out to White Waltham?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we’re fully insured.
How long does it take to clean an air handling unit?
Typically the clean takes half a day to a full day per unit, with large plant planned over several shifts. We plan the shutdown around that, including evenings or weekends.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
What’s included in an AHU clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
What affects the quote in White Waltham
Your quote is based on your site. We consider:
- One-off work versus a regular cycle
- How many systems or sites are involved
- How easy every part is to reach
- Working hours and out-of-hours timing
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide photos of the system and the area around it
- Problems your staff have spotted
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, give us a ring on 0345 646 2711, or email photos.
