How we handle AHU cleaning in Blendon
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers supply and extract fans, heating and cooling coils and drain trays, and people most often call us about units that have only ever had filter changes and coils clogged with dust and debris.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Blendon, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
The paperwork matters as much as the work. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What affects the cost of AHU cleaning
We don’t publish a price list, because sites vary so much. What we look at:
- One-off work versus a regular cycle
- Whether we need access equipment or extra panels
- Any permits to work or inductions
- 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’ll explain each part.
Asking for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- A few general shots of the system
For a fixed quote, ring 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.

Honest limits
AHU cleaning cannot fix everything, and we’d rather say so up front. It won’t put right:
- Airflow problems caused by the system’s design
- Mechanical faults with motors, belts or bearings
- Damaged coils beyond cleaning
If in doubt, ring 0345 646 2711 or send us an email and we’ll say what we think before booking.
What the work covers
- Filter sections
- Dampers and louvres
- Drain trays
- Heating and cooling coils
- Internal panels
- Supply and extract fans
What we do, step by step
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them. Most London sites cannot stop for the day, so work in Blendon is normally done overnight, early in the morning or at weekends.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Move anything stored near the system
- Mention any sign-in, permit or induction we need
Ask for a quote
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
Advice
For landlords and multi-site operators
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Common problems we fix in Blendon
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Common reasons sites call us are:
- Odours coming through the supply air
- Leaves and litter drawn into the unit
- Fan sections that haven’t been cleaned in years
- Blocked condensate drains and slimy trays
If you manage offices or shops near Albany Park station, their ventilation can be inspected and cleaned out of hours.
What your quote should include
- When they can work, and whether that’s outside your opening hours
- Whether a written report and photos are included
- What’s included in the scope, part by part
- Whether the price is fixed
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Part by part
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with photos so repairs can be planned.
