Putney buildings and their air
Going by the FSA’s register, there are about 43 schools, colleges and universities, about 66 hospitals, care homes and childcare premises and about 5 hotels, B&Bs and guest houses serving food in Putney and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Getting kit to a London plant room typically means lifts, stairs and an agreed loading slot. Royal Hospital for Neuro-disability is the nearest hospital, about 0.8 miles south-east of Putney. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Royal Hospital for Neuro-disability, about 0.8 miles south-east, is the nearest hospital to Putney, and healthcare sites of every size need their supply air kept clean. For schools like Our Lady of Victories Catholic Primary School, the holidays are the usual time to inspect and clean ventilation. If you run an office near Putney station, its supply ductwork can gather dust for years before anyone looks inside.

AHU cleaning in Putney
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. If you have dirty filters cutting the airflow and fan sections that haven’t been cleaned in years, we can put it right.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in Putney.
A written report with photos follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
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. Reaching it takes a specialist with the right equipment.
Different parts, different methods
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
Leave it or put it right?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before work begins.

The process
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. If your building in Putney has sign-in rules, permits or key holders, mention them when you book.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure someone can let us in and lock up afterwards
- Mention any parking or loading restrictions

FAQs for Putney
Can you come to Putney after we close?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Putney needn’t be disturbed. Let us know the hours you’re closed and we will book within them.
How do you handle parking and loading in Putney?
Tell us where a van can stop near your site in Putney, and about any building rules on loading. Working overnight, as we often do in London, normally makes it simpler.
What happens if you can’t reach some of it?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Do you work in Putney?
Yes. Our technicians work in Putney, as part of our area across London and the South East.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
How often do AHUs need cleaning?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
Do you need to switch the unit off?
Yes, for the time we’re working on it. Out-of-hours work is available to keep disruption down.

Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Check the drain tray is emptying during routine visits
- Report water on the plant room floor
- Book the next check in line with the report
- Change filters on schedule and log each change
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
Multi-site and managed buildings
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
