How we handle AHU cleaning in New Addington
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. Every job starts with a survey, from pictures or on site, followed by a fixed quote before any cleaning starts. Common call-outs are for air handling units never cleaned inside and dirty filters cutting the airflow, across filter sections, dampers and louvres and drain trays.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in New Addington is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building to keep disruption down.

How the visit works
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, 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 New Addington.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Clear the space around the work
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Different parts, different methods
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
New Addington buildings and their air
The FSA’s food hygiene register lists about 14 schools, colleges and universities and about 17 care, childcare and hospital premises with registered kitchens or food service in and around New Addington, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Ventilation cleaning in London buildings is normally planned for evenings or weekends. About 1.8 miles south of New Addington is Warlingham Park 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.
Classrooms and halls at schools such as Rowdown Primary School are easiest to work in when pupils are away.

What we are called out for in New Addington
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:
- Plant that has been serviced but not cleaned
- Dirty fans and fan housings
- Air handling units due a clean after building work
- Dust-coated heating and cooling coils
Hospitals such as Warlingham Park Hospital (about 1.8 miles south) show how much a building can rely on clean ventilation, and smaller healthcare sites near New Addington are no different.

New Addington: your questions answered
Do you do school ventilation cleaning in New Addington in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 14 schools and colleges on the FSA’s register within roughly a mile and a half of New Addington, it pays to plan holiday dates ahead. Send us your term dates when you ring 0345 646 2711, or send details by email, and we will fit the work in.
Can you work in New Addington outside opening hours?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Can you price the work without visiting?
Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We’ll flag anything we notice during the clean.
Why act early in New Addington
Stuffy rooms and stale smells in a building in New Addington can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. In New Addington, as across London, ductwork often passes through shared risers and other people’s space.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711 or drop us a line for straight advice and a fixed quote.
Why book with us
- Work around your opening hours, with 24/7 emergency cover
- Fixed quotes, normally within one working day
- One number for every site across the South East and London
- CHAS and SafeContractor accredited, with ISO 9001

Staff cleaning versus specialist work
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. Reaching it takes a specialist with the right equipment.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Between visits
Simple habits between visits make a real difference. We recommend:
- Keep filter changes on time and recorded
- Don’t ignore odours coming through the grilles
- Make sure the unit’s access doors open easily
- Keep the area around the fresh air intake clear
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
