AHU cleaning in Marlow Bottom
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with pictures, so you can see the unit’s condition for yourself. If you’re dealing with dust built up on fan impellers and plant that needs cleaning after a refit, we can help.
Work in a small place like Marlow Bottom starts with agreeing access and timings.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Signs you need AHU cleaning in Marlow Bottom
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
Common reasons sites call us include:
- Plant that needs cleaning after a refit
- Dirty filters cutting the airflow
- Condensate trays that won’t empty
- Units that have only ever had filter changes
For schools like Burford School, the holidays are the usual time to inspect and clean ventilation.

Common questions in Marlow Bottom
Can the work in Marlow Bottom be done at night or at weekends?
Yes, we can come after you close and finish before you open. The work in Marlow Bottom can fit around your hours. When you ring 0345 646 2711 or use the quote form, mention when the site is quiet.
Do you work in villages like Marlow Bottom?
Yes, smaller places are covered as well as towns. A survey first, from photos or a visit, means we arrive with the right kit.
Are you accredited?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, and new panels can be fitted.
Is there a report after cleaning?
Yes, both a certificate and a report with pictures. It includes a recommended date for the next check.
Where does the waste go?
It leaves the site with us at the end of the visit. During the work, it’s contained to keep the area clean.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
What happens if you can’t reach some of it?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
Why act early in Marlow Bottom
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Rural sites cannot always move to another kitchen or room when something fails.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.

What affects the quote in Marlow Bottom
You will get a fixed price before work begins. It takes into account:
- What state the system is in
- Site rules, permits and inductions
- How big the system is
- Travel, parking and unloading
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711 or use the quote form, and we will explain what it covers.
Asking for a quote
You don’t need the technical terms. It helps if you can send:
- Any access panels or hatches you can see
- Problems your staff have spotted
- Wide photos of the system and the area around it
- Your opening hours and when the area is out of use
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
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. The inside of ducts and units needs a specialist.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Plan the next inspection before the last report gets filed away
- Make sure the unit’s access doors open easily
- Report water on the plant room floor
- Make sure condensate is draining away
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. 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.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
