AHU Cleaning in Shooter's Hill
AHU cleaning for commercial sites in Shooter's Hill and across Greater London. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Blocked condensate drains and slimy trays
- Dust built up on fan impellers
- Stale or musty smells from the ventilation
The process
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes half a day to a full day per unit, with large plant planned over several shifts, and we clear up before we go. In a London area like Shooter's Hill, parking, loading and building access are planned before the day of the work.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
How to prepare
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
How to get a quote
Getting a quote does not take long. Send a few details and pictures, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Advice
AHU cleaning in Shooter's Hill
Where a building in Shooter's Hill has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. The work covers filter sections, heating and cooling coils and supply and extract fans, and people most often call us about dust-coated heating and cooling coils and air handling units with blocked filters.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Shooter's Hill is usually planned out of hours. Loading and parking are planned with the building first.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Between visits
Think of this as the after-treatment advice, in brief:
- File each AHU report in the maintenance log
- Don’t ignore odours coming through the grilles
- Report stiff or damaged access doors
- Watch for drips or damp patches near the plant
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
Common questions in Shooter's Hill
How do you handle parking and loading in Shooter's Hill?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Night visits tend to make loading easier on London streets.
Can you clean school ventilation in Shooter's Hill during the holidays?
Yes, holiday work suits schools best. There are about 50 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Shooter's Hill. Booking early in the term gives the best choice of holiday dates.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Do you look at the system first?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
What happens to the waste?
It leaves the site with us at the end of the visit. While we work, it’s kept contained so the area stays clean.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and clean down when we finish.
How long does an AHU clean take?
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 we’ll confirm the time when we quote.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Shooter's Hill buildings and their air
There are about 50 schools, colleges and universities and about 52 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register in and around Shooter's Hill, up to about a mile and a half out. 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. The nearest hospital to Shooter's Hill is Memorial Hospital, about within half a mile west. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
If you manage shops or offices close to Falconwood station, a TR19® Air inspection shows whether the ductwork needs cleaning. Wherever a school like Shooters Hill Sixth Form College has ducted ventilation, a half-term visit keeps the work out of lesson time.

Do you need AHU cleaning in Shooter's Hill?
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that is where slime and odours start.
Common reasons sites call us are:
- Plant that has been serviced but not cleaned
- Plant that needs cleaning after a refit
- Filters that are clogged or overdue
- Rooms that smell stuffy when the system runs
Healthcare ventilation, from large hospitals like Memorial Hospital (about within half a mile west) to small clinics, depends on clean filters, coils and ducts.

Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare in Shooter's Hill and across Greater London. Work can be phased by floor, building or site to keep disruption down.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
In-house cleaning or a specialist?
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 can diagnose it and quote.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
What AHU cleaning can’t fix
We will not sell you work that does not address the problem, so these are the things it will not cover:
- Coils that are corroded or leaking and need replacing
- Mechanical faults with motors, belts or bearings
- Airflow problems caused by the system’s design
If you are not sure, just phone us on 0345 646 2711, or send details by email and we’ll give you a straight answer before you book.
