AHU cleaning in Well Hall
Our AHU cleans for sites in Well Hall cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. The work covers heating and cooling coils, drain trays and supply and extract fans, and people most often call us about dust built up on fan impellers and units needing a clean before a new tenant or handover.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Well Hall, dust and debris build up in the units and ductwork over time.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Well Hall: your questions answered
Can parking be tricky for a job in Well Hall?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Do you work at weekends in Well Hall?
Yes, nights and weekends are routine for us. It means the site in Well Hall keeps running as normal. When you give us a ring on 0345 646 2711 or use the quote form, mention when the site is quiet.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
Can you price the work without visiting?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after pictures. They’re worth keeping with the plant records.
What happens if you cannot reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Ventilation in Well Hall buildings
There are about 41 schools, colleges and universities and about 37 care, childcare and hospital premises on the FSA’s food hygiene register in and around Well Hall, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Well Hall’s nearest hospital, Eltham Community Hospital, is about 0.6 miles south. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. In London, ventilation plant is often on the roof or below ground, so the work is normally done out of hours.
For workplaces around Eltham station with mechanical ventilation, cleaning can be done in the evening or at weekends. Healthcare ventilation, from large hospitals like Eltham Community Hospital (about 0.6 miles south) to small clinics, depends on clean filters, coils and ducts.

Why act early in Well Hall
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. A busy site in Well Hall builds up dirt and wear quickly, so putting it off makes the eventual job larger.

What the work involves, part by part
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey so the quote reflects it.
Fixed quotes for AHU cleaning in Well Hall
The quote reflects the site in front of us. We consider:
- The size of the system
- When the work can happen, such as evenings, overnight or weekends
- Any permits to work or inductions
- Access, including roofs, risers and ceiling voids
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, phone us on 0345 646 2711 or send us an email for straight advice and a fixed quote.
What we need to know
What to send for a quote:
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
For a fixed quote, give us a ring on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
Do you need AHU cleaning in Well Hall?
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
Common reasons sites call us are:
- Debris and leaves in the fresh air intake
- Air handling units never cleaned inside
- Drain trays holding standing water
- Dust-coated heating and cooling coils
Classrooms and halls at schools such as Gordon Primary School are easiest to work in when pupils are away.

Aftercare tips
So the system stays in good health:
- Make sure condensate is draining away
- Make sure the unit’s access doors open easily
- Report musty smells from the vents straight away
- Do not store bins or materials near the intake
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
Managing agents and facilities teams in Well Hall
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
How the visit works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes one overnight shift for many single units, with bigger plant phased. Before any visit in Well Hall, we agree where the van can stop and how equipment reaches the system.

- 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.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
