AHU cleaning in Pattiswick
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you’re dealing with dust-coated heating and cooling coils and leaves and litter drawn into the unit, we can help.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Signs you need AHU cleaning in Pattiswick
Whatever surrounds a building in Pattiswick, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
Common reasons sites call us are:
- Dirty coils holding back the airflow
- Dirty filters cutting the airflow
- Dust built up on fan impellers
- Units needing a clean before a new tenant or handover
If you manage a school such as Stisted Church of England Primary Academy, ventilation cleaning is best booked for the holidays.

What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- When the work can happen, such as evenings, overnight or weekends
- Where the site is and how we reach it
- Whether several sites go on one quote
- Site rules, permits and inductions
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.
What to send for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To get going, call 0345 646 2711, or send details by email.
What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
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, alongside our reports.
How the job changes from site to site
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.

When something else is needed
To be straight with you, there are a few things this work will not fix:
- Dirty ducts beyond the unit itself
- Building management system faults
- Mechanical faults with motors, belts or bearings
Not sure which it is? You can give us a ring on 0345 646 2711 or send us an email and we will tell you honestly before booking.
Parts of the system we cover
- Supply and extract fans
- Filter sections
- Internal panels
- Heating and cooling coils
- Dampers and louvres
- Drain trays
Leave it or put it right?
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. Out of sight is the usual reason a rural system goes too long without attention.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, ring 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.

Common questions in Pattiswick
Do you cover Pattiswick for AHU cleaning?
Yes. Our area runs across London and the South East, Pattiswick included. You can call 0345 646 2711 or email us and tell us what needs doing.
Can you come to Pattiswick after we close?
Yes, we can come after you close and finish before you open. It means the site in Pattiswick keeps running as normal. Your opening times are the first thing we ask for.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
Can you quote from photos?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
How long will the unit be out of action?
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, out of hours if needed.
What happens if you cannot reach some of it?
Anything we cannot reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after pictures. Keep them in the maintenance log.
