AHU Cleaning in Plumstead
Air handling unit cleaning in Plumstead, surveyed first and signed off with a written report and pictures. Call for a fixed quote.
- Dirty fans and fan housings
- Drain trays holding standing water
- Dirty coils holding back the airflow
What we are called out for in Plumstead
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Keep an eye out for these warning signs:
- Units that have only ever had filter changes
- Filters that are clogged or overdue
- Dust-coated heating and cooling coils
- Leaves and litter drawn into the unit
If you manage a school such as South Rise Primary School, ventilation cleaning is best booked for the holidays.
Questions to ask before booking
- What records you’ll receive afterwards
- Whether the price is fixed
- What hours they’ll be on site
- Whether the whole system is included, or only the parts that are easy to reach
About our AHU cleaning in Plumstead
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers dampers and louvres, internal panels and filter sections, and the jobs we see most are dust built up on fan impellers and blocked condensate drains and slimy trays.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. In Plumstead, as elsewhere, cleaning starts with an inspection of what’s there.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What we do, step by step
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Plumstead.
- 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.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Move anything stored near the system
- Agree a time when the area can be out of use

What affects the quote in Plumstead
The quote reflects the site in front of us. We take into account:
- Travel, parking and unloading

- The condition we find in the survey
- Site rules, permits and inductions
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before we start.
What to send for a quote

Need a price for AHU cleaning? Please call 0345 646 2711 or use the quote form and tell us about the site. We’ll explain what we’d do and send a fixed quote before anything is booked.
Multi-site and managed buildings
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Questions from Plumstead
Do you do school ventilation cleaning in Plumstead in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Plumstead, the Food Standards Agency lists about 48 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you come to Plumstead after we close?
Yes, nights and weekends are routine for us. It means the site in Plumstead keeps running as normal. Tell us your opening hours when you ask for a quote.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
What happens if you can’t reach some of it?
We record them on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
How long does an AHU clean take?
Cleaning takes half a day to a full day per unit, with large plant planned over several shifts. Bigger units can be phased, so call 0345 646 2711 or use the quote form to talk it through.
What’s included in an AHU clean?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
Do you survey before quoting?
Yes. We always survey first, from your pictures and details, or with a visit where needed. A fixed quote follows.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What AHU cleaning looks like in Plumstead
The FSA’s food hygiene register lists about 48 schools, colleges and universities and about 41 hospitals, care homes and childcare premises with registered kitchens or food service across Plumstead and its immediate surroundings (about a mile and a half). Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. Plumstead’s nearest hospital, British Hospital for Mothers and Babies, is about 1.3 miles west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Hospitals such as British Hospital for Mothers and Babies (about 1.3 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Plumstead are no different. If you manage shops or offices close to Plumstead station, a TR19® Air inspection shows whether the ductwork needs cleaning.

Why act early in Plumstead
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. A building in Plumstead may have flats or offices above and alongside, and a fault in the system can affect them too.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.

What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
