About our AHU cleaning in Kitts End
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from pictures or a site visit, and send you a fixed quote before any cleaning starts. The work covers supply and extract fans, filter sections and dampers and louvres, and common reasons people get in touch are air handling units with blocked filters and stale or musty smells from the ventilation.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. In Kitts End, as elsewhere, cleaning starts with an inspection of what’s there.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes from a few hours for a compact unit to a day or more for a large one, and the area is cleaned down before we leave. In Kitts End, as across London, we typically work overnight or at weekends and hand the site back ready to open.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
How to prepare
- Mention any parking or loading restrictions
- Allow time for equipment near the work to be turned off and cool down
- Move anything stored near the system
Ask for a quote
To get a fixed quote, call 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We usually come back within one working day.

What we’re called out for in Kitts End
Whatever surrounds a building in Kitts End, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and the finer material travels on.
Clients normally contact us after spotting something like this:
- Blocked condensate drains and slimy trays
- Dust-coated heating and cooling coils
- Dirty filters cutting the airflow
- Air handling units never cleaned inside
Healthcare buildings such as Barnet General Hospital, about 1.6 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Kitts End, yours matters too.
Questions to ask before you book
- Exactly which parts of the system are covered
- Proof of accreditation you can verify
- What insurance they carry
- Whether a written report and photos are included
Aftercare tips
Here’s the after-treatment advice, in brief:
- Make sure the unit’s access doors open easily
- Check the drain tray is emptying during routine visits
- Store the TR19 paperwork where auditors can find it
- Report water on the plant room floor
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.

What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

Leave it or put it right?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. That makes the next inspection of a building in Kitts End simpler. Leaving it on a busy London site only adds to the work.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

How the job changes from site to site
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
What affects the quote in Kitts End
Sites vary more than people expect. What affects the quote:
- Parking and loading at the site
- The condition of the system
- The number of sites or systems
- When the work can happen, such as evenings, overnight or weekends
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before any work starts.
Helping us quote
To help us quote quickly, send us:
- Photos showing the whole system and its surroundings
- How we’d reach plant on a roof or in a plant room
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The site address and the type of premises
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.
