AHU cleaning in Custom House, done properly
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so you can see the unit’s condition for yourself. Common call-outs are for dirty fans and fan housings and units needing a clean before a new tenant or handover, on internal panels, filter sections and drain trays.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Custom House is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
Good records are part of the job. Each visit is written up with photos, 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 AHU cleaning can’t fix
Before booking, it helps to know what’s not included:
- Dirty ducts beyond the unit itself
- Airflow problems caused by the system’s design
- Building management system faults
If in doubt, phone us on 0345 646 2711 or use the quote form and we will say what we think.
Parts of the system we cover
- Dampers and louvres
- Internal panels
- Supply and extract fans
- Drain trays
- Filter sections
- Heating and cooling coils
Looking after it afterwards
So the system stays in good health:
- Report stiff or damaged access doors
- Stick to the filter change plan
- Check the drain tray is emptying during routine visits
- Diary the inspection date recommended in the report
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Landlords, agents and facilities managers
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. Where responsibility is shared, records matter even more.
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Work can be phased by floor, building or site around the people who use them.

Common questions in Custom House
Can you work in Custom House outside opening hours?
Yes, out-of-hours work is a big part of what we do. The work in Custom House can fit around your hours. Let us know the hours you’re closed and we will book within them.
Does London parking affect a job in Custom House?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. If the building has a loading slot system, we’ll book into it.
Can you quote from pictures?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Is there a survey before the work?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How do you protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
AHU cleaning in Custom House: local notes
There are about 52 schools, colleges and universities, about 41 caring premises (care homes, nurseries and hospitals) and about 18 hotels and B&Bs on the FSA’s food hygiene register in Custom House and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot. Albert Dock Seamen's Hospital is the nearest hospital, about 0.5 miles north-east of Custom House. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Wherever a school like St Joachim's Catholic Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. If you run an office near Custom House station, its supply ductwork can gather dust for years before anyone looks inside.

Do you need AHU cleaning in Custom House?
Whatever surrounds a building in Custom House, 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.
Most sites get in touch after spotting something like this:
- Dust built up on fan impellers
- Air handling units due a clean after building work
- Coils clogged with dust and debris
- Condensate trays that will not empty
Healthcare ventilation, from large hospitals like Albert Dock Seamen's Hospital (about 0.5 miles north-east) to small clinics, depends on clean filters, coils and ducts.
Before booking anyone
- Which accreditations they hold, and whether you can check them
- Whether a survey comes first
- When the next visit should be, and why
- When they can work, and whether that’s outside your opening hours
What the work involves, part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
What happens on the day
Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. The visit itself takes from a few hours for a compact unit to a day or more for a large one. Loading bays, visitor permits and roof access are the first things we ask about for a site in Custom House.
- We survey the unit from photos or on site and agree what’s included.
- 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.
- You get a TR19® certificate and a photo report.
Before we arrive
- Clear the space around the work
- Make sure someone can let us in and lock up afterwards
- Mention any parking or loading restrictions
