About our AHU cleaning in East Hill
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with pictures, so you can see the unit’s condition for yourself. The work covers internal panels, filter sections and supply and extract fans, and the jobs we see most are dirty coils holding back the airflow and air handling units never cleaned inside.
For a building in or near East Hill, access is agreed in advance and the visit is planned around the journey.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Looking after it afterwards
To keep the system working properly between visits:
- Stick to the filter change plan
- Report water on the plant room floor
- Store the TR19 paperwork where auditors can find it
- Plan the next inspection before the last report gets filed away
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.

Honest limits

- A system that’s undersized for the building
- Coils that are corroded or leaking and need replacing
- The supply and extract ducts, quoted separately

East Hill questions
Is AHU cleaning available in East Hill?
Yes. We work across London and the South East, and East Hill is part of that. A fixed quote normally follows within one working day of the survey details.
Will you come out to East Hill?
Yes, East Hill is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Do you do ventilation duct cleaning too?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can quote for both.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
When to call us in East Hill
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Common reasons sites call us are:
- Air handling units with blocked filters
- Air handling units due a clean after building work
- Leaves and litter drawn into the unit
- Plant that has been serviced but not cleaned
Around East Hill, as anywhere, ventilation cleaning begins with an inspection.
What your quote should include
- Exactly which parts of the system are covered
- If they look at the system before pricing
- What insurance they carry
- What happens if part of the system can’t be accessed
What happens on the day
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, clear away and hand over the paperwork. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Photos of the system and how to reach it help us plan a visit to East Hill.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Let us know when the site is closed or quiet

Fixed quotes for AHU cleaning in East Hill
There’s no set price list, because no two systems are the same. The quote depends on:
- Site rules, permits and inductions
- A single visit or a regular plan
- Working hours and out-of-hours timing
- The number of sites or systems
The cost depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before any work starts, so there are no surprises.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
- A few general shots of the system
- Detail shots of panels, filters and grilles
Getting a quote doesn’t take long. Call or email with a few details and you will usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Leave it or put it right?
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. In a small place like East Hill, a system that fails can take a site out of use.
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
