AHU cleaning in Woldingham, done properly
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. The work covers drain trays, filter sections and heating and cooling coils, and people most often call us about dust built up on fan impellers and dirty coils holding back the airflow.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

FAQs for Woldingham
Can you do AHU cleaning in Woldingham?
Yes. Our area runs across London and the South East, Woldingham included. You can phone us on 0345 646 2711, or send details by email and let us know what needs doing.
Can you get to a site in Woldingham?
Yes, we work in villages as well as towns, and Woldingham is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can quote for both.
Do you need to switch the unit off?
Yes, while the clean is under way. We can work evenings, overnight or at weekends to keep disruption down.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can you price the work without visiting?
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.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.

When something else is needed
In fairness, some problems need a different fix:
- Leaking heating or cooling coils
- The supply and extract ducts, quoted separately
- Ventilation that was badly designed in the first place
If you’re not sure, just ring 0345 646 2711 or email us and we will give you a straight answer.

What affects the quote in Woldingham
The survey tells us what the work involves. The main factors are:
- The scale of the work
- Whether we need access equipment or extra panels
- Site rules, permits and inductions
- One-off work versus a regular cycle
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, call us on 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.
What to send for a quote
There’s no need for technical detail. It helps if you can send:
- Your opening hours and when the area is out of use
- Wide photos of the system and the area around it
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, call 0345 646 2711 or use the quote form.
Landlords, agents and facilities managers
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
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 each one has its own record.
The process
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 a single shift for a typical unit, longer for large or heavily soiled ones. Pictures of the system and its access let us plan the work in Woldingham before we set off.
- 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.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about permits to work or site inductions
- Clear the space around the work
Ask for a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, ring 0345 646 2711, or send details by email.

When to call us in Woldingham
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Common reasons sites call us include:
- Coils clogged with dust and debris
- Odours coming through the supply air
- Units needing a clean before a new tenant or handover
- Dirty fans and fan housings
Healthcare buildings such as Warlingham Park Hospital, about 2.2 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near Woldingham, yours matters too.
What to look for in a quote
- What insurance they carry
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the work can be done while the site is closed
- How areas they can’t reach will be recorded
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Change filters on schedule and log each change
- Don’t store bins or materials near the intake
- Keep the certificate and photo report with the plant records
- Make sure condensate is draining away
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Keep the area around the intake clear. What’s near the intake ends up in the unit.

Why deal with it now?
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. Out of sight is the usual reason a rural system goes too long without attention.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before work begins.
