How the visit works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes half a day to a full day per unit, with large plant planned over several shifts. If your building in Neasden has sign-in rules, permits or key holders, mention them when you book.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.

AHU cleaning for kitchens and businesses in Neasden
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you’re dealing with blocked condensate drains and slimy trays and dirty filters cutting the airflow, we can put it right, from dampers and louvres, heating and cooling coils and supply and extract fans onwards.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Neasden, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Leave it or put it right?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
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 talk you through it.

Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Ventilation cleaning in London buildings is typically planned for evenings or weekends.

Different parts, different methods
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Internal casing and panels
We open each section through its doors and close them securely when we are done, and check every one is shut.
What we are called out for in Neasden
Whatever surrounds a building in Neasden, 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.
These are the problems we see most often:
- Debris and leaves in the fresh air intake
- Plant that needs cleaning after a refit
- Fan sections that haven’t been cleaned in years
- Filters that are clogged or overdue
Neasden Hospital, about 0.7 miles south-west, is the nearest hospital to Neasden, and healthcare sites of every size need their supply air kept clean.
Questions to ask before booking
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the figure could change on the day
- Whether inaccessible sections are listed on the report
- Whether the quote shows VAT

- A single visit or a regular plan
- How many systems or sites are involved

The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.

Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Store the TR19 paperwork where auditors can find it
- Report stiff or damaged access doors
- Diary the inspection date recommended in the report
- Don’t store bins or materials near the intake
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Neasden: your questions answered
Can ventilation in schools around Neasden be cleaned out of term?
Yes, out-of-term visits are normal for schools. There are about 51 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Neasden. Just call 0345 646 2711, or email photos with your term dates and we will plan around them.
Can you come to Neasden after we close?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. When you call 0345 646 2711 or email us, mention when the site is quiet.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, with new panels fitted where necessary.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
When should our AHU next be cleaned?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
How much notice should we give?
The more notice, the better, especially for out-of-hours work. We typically quote within one working day, and emergencies are covered by our 24/7 line.
