About our AHU cleaning in Blackheath
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 dampers and louvres, supply and extract fans and drain trays, and common reasons people get in touch are dirty fans and fan housings and air handling units with blocked filters.
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 Blackheath, as elsewhere, cleaning starts with an inspection of what’s there.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Change filters on schedule and log each change
- Watch for drips or damp patches near the plant
- Do not store bins or materials near the intake
- Store the TR19 paperwork where auditors can find it
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Common questions in Blackheath
Can a school’s ventilation in Blackheath be done out of term time?
Yes, out-of-term visits are normal for schools. There are about 47 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Blackheath. Send us your term dates when you ring 0345 646 2711 or use the quote form, and we will fit the work in.
Does London parking affect a job in Blackheath?
A loading bay, a visitor permit or off-street space near the site in Blackheath makes the visit easier to plan. If the building has a loading slot system, we’ll book into it.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
How do you keep the site clean during the work?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will usually reply within one working day.
How long does it take to clean an air handling unit?
It takes a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
How the visit works
Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, clear away and leave you the report. The visit itself takes from a few hours for a compact unit to a day or more for a large one. If your building in Blackheath has sign-in rules, permits or key holders, mention them when you book.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Dig out any earlier paperwork for the system
- Clear the space around the work

What AHU cleaning looks like in Blackheath
Food Standards Agency records list about 47 schools, colleges and universities, about 76 hospitals, care homes and childcare premises and about 9 hotels and B&Bs registered as food businesses in Blackheath and the streets around it, up to about 1.5 miles out. Busy, occupied buildings like these are where clean supply air matters most. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot. About 1.1 miles north of Blackheath is Greenwich District Hospital, the nearest hospital. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
If you manage a school such as All Saints' Church of England Primary School Blackheath, ventilation cleaning is best booked for the holidays. Healthcare ventilation, from large hospitals like Greenwich District Hospital (about 1.1 miles north) to small clinics, depends on clean filters, coils and ducts.

Honest limits
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It will not put right:
- Controls and BMS settings that run the unit
- Airflow problems caused by the system’s design
- Faulty motors, drives or bearings
If you are not sure, just call us on 0345 646 2711 or send us an email and we’ll give you a straight answer.
What we work on in Blackheath
- Drain trays
- Heating and cooling coils
- Filter sections
- Supply and extract fans
- Dampers and louvres
- Internal panels
Leave it or put it right?
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. In Blackheath, as across London, ductwork often passes through shared risers and other people’s space.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.
