AHU cleaning in Shillington: local notes
About 4.9 miles east of Shillington is Fairfield Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. We cover Shillington, about 36 miles from central London, as part of our work across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
School buildings such as Shillington Lower School are normally done in the holidays, so classrooms are not disturbed.

How we handle AHU cleaning in Shillington
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. If you have dirty coils holding back the airflow and air handling units with blocked filters, we can put it right.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

How the job changes from site to site
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
How the visit works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. We agree a date with you, plan the drive to Shillington and turn up when the site is quiet.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- 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.
- We close up the unit and send the certificate and before and after pictures.
How to prepare
- Arrange a key holder or contact on site
- Make sure equipment near the work can be switched off and left to cool
- Mention any sign-in, permit or induction we need

What affects the cost of AHU cleaning
Your quote is based on your site. We take into account:
- Whether we need access equipment or extra panels

- The number of sites or systems
- Where the site is and how we reach it
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.
Asking for a quote
What to send for a quote:
- A few general shots of the system
- Any access panels or hatches you can see
- Any previous report or certificate
- Problems your staff have spotted
Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Then call us on 0345 646 2711 or send us an email.

Your questions about AHU cleaning in Shillington
Can the work in Shillington be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. That way a site in Shillington does not have to lose a day’s trading. Just call 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Do you offer AHU cleaning in Shillington?
Yes, Shillington is covered. Get in touch with the details and we will arrange a survey.
Can you price the work without visiting?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
What about areas you cannot get to?
We record them on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
How long does an AHU clean take?
Typically the clean takes from a few hours for a compact unit to a day or more for a large one. The shutdown is planned to fit, out of hours if needed.
What happens if it’s left?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. A fault that closes a site in a village like Shillington affects everyone who depends on it.
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or email us, and we will talk you through it.

In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
When to call us in Shillington
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
The symptoms we’re asked about most are:
- Blocked condensate drains and slimy trays
- Rooms that smell stuffy when the system runs
- Dust-coated heating and cooling coils
- Fan sections that haven’t been cleaned in years
Fairfield Hospital, about 4.9 miles east, is the nearest hospital to Shillington, and healthcare sites of every size need their supply air kept clean.
