- Dirty fans and fan housings
- Units needing a clean before a new tenant or handover
- Debris and leaves in the fresh air intake
Part by part
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
How we handle AHU cleaning in The City
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you have units needing a clean before a new tenant or handover and intake sections clogged with outdoor debris, we can put it right, from supply and extract fans, drain trays and dampers and louvres onwards.
Work in a small place like The City starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Ventilation in The City buildings
The City is about 35 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you. Wycombe Hospital is the nearest hospital, about 5 miles south-east of The City. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
Wherever a school like Radnage Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. If you run a surgery, dental practice or care home near The City, clean ventilation matters as much to you as to a hospital like Wycombe Hospital (about 5 miles south-east).

What affects the quote in The City
The price is fixed before any work begins. It’s based on:
- The scale of the work
- A single visit or a regular plan
- Any permits to work or inductions
- The number of sites or systems
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.
Helping us quote
Many jobs can be priced from photos and some basics. Useful things to send:
- The paperwork from the last visit, if you have it
- Wide photos of the system and the area around it
- How we’d reach plant on a roof or in a plant room
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
To get a fixed quote, ring 0345 646 2711 or drop us a line 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 normally come back within one working day.
When it’s something else
We will not sell you work that does not address the problem, so these are the things it will not cover:
- Ventilation that was badly designed in the first place
- Dirty ducts beyond the unit itself
- Damaged coils beyond cleaning
If in doubt, call 0345 646 2711 or send us an email and we will say what we think before booking.

- Filter sections
- Supply and extract fans
- Internal panels

What we do, step by step
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on.

- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.

How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Questions from The City
Do you cover smaller places like The City?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Can you work in The City outside opening hours?
Yes. We work evenings, overnight and at weekends. That way a site in The City does not have to lose a day’s trading. Just ring 0345 646 2711, or email photos with your opening times and we’ll plan around them.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Make sure condensate is draining away
- Keep filter changes on time and recorded
- Watch for drips or damp patches near the plant
- Clear leaves and litter away from the intake
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
Managing agents and facilities teams in The City
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
