Common questions in Ratley
Is Ratley in your area for AHU cleaning?
Yes, Ratley is within the area we cover across London and the South East. A fixed quote normally follows within one working day of the survey details.
Can the work in Ratley be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Are you insured?
Yes. We are fully insured, and we can share the details when you need them.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before we start, and anything we remove is contained. At the end, the area is cleaned down.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What’s included in an AHU clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
AHU cleaning for kitchens and businesses in Ratley
If the units serving a building in Ratley have only had filter changes for years, 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, internal panels and dampers and louvres, and people most often call us about rooms that smell stuffy when the system runs and blocked condensate drains and slimy trays.
In a village or hamlet like Ratley, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.

- 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.
- The fan and drain tray are cleaned and the drain checked.

Multi-site and managed buildings
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.

What else we do in Ratley
Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
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. That part needs specialist access and equipment.
How the job changes from site to site
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey, before we quote.
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Signs you need AHU cleaning in Ratley
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
It’s time to book a visit if you see:
- Dirty coils holding back the airflow
- Drain trays holding standing water
- Stale or musty smells from the ventilation
- Air handling units never cleaned inside
Around Ratley, an air handling unit’s drain tray is checked for standing water as a matter of course.

What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Parking and loading at the site
- The condition of the system
- The number of sites or systems
- Site rules, permits and inductions
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, call 0345 646 2711, or send details by email for straight advice and a fixed quote.
What to send for a quote
There’s no need for technical detail. It helps if you can send:
- The times we could work without disrupting the site
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
- The site address and the type of premises
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Then phone us on 0345 646 2711 or drop us a line.
