AHU cleaning in Blackwall, done properly
We clean air handling units for buildings in Blackwall and across Greater London, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers filter sections, internal panels and dampers and louvres, and the jobs we see most are stale or musty smells from the ventilation and plant that has been serviced but not cleaned.
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. In a building in Blackwall, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Blackwall: your questions answered
Do you work at weekends in Blackwall?
Yes, nights and weekends are routine for us. That way a site in Blackwall does not have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Do you clean school ventilation in Blackwall in the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 56 schools, colleges and universities with registered kitchens within about a mile and a half of Blackwall. You can call 0345 646 2711, or send details by email with the dates the site is empty.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
Do you have insurance?
Yes. Full insurance covers our work, and we have been trading since 2009.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply ring 0345 646 2711, or email photos.
What accreditations do you have?
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.
Do you work in Blackwall?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Blackwall included.
Is a quote from pictures possible?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Aftercare tips
Once we’ve finished, these simple steps help:
- Note any water around the unit or leaks below it
- Plan the next inspection before the last report gets filed away
- Keep filter changes on time and recorded
- Keep the area around the fresh air intake clear
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.

What we do, step by step
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and hand over the paperwork. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Blackwall.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Tell us where we can park and unload
- Agree a time when the area can be out of use
- Make sure someone can let us in and lock up afterwards
How to get a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Related advice
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Do you need AHU cleaning in Blackwall?
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
Signs it’s time to call us include:
- Dust-coated heating and cooling coils
- Air handling units never cleaned inside
- Dirty filters cutting the airflow
- Dust built up on fan impellers
For workplaces around Canary Wharf station with mechanical ventilation, cleaning can be done in the evening or at weekends.

What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- How big the system is
- Parking and loading at the site
- The condition we find in the survey
- Whether several sites go on one quote
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 will go through it with you.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Any previous report or certificate
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- Where the site is and what kind of site it is
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711 or send us an email.
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
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 they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Leave it or put it right?
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in Blackwall simpler. In Blackwall, a planned overnight visit is much easier than closing unexpectedly.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we will price it together.
