Sonning Common: your questions answered
Is Sonning Common in your area for AHU cleaning?
Yes. We work across London and the South East, and Sonning Common is part of that. Just give us a ring on 0345 646 2711 or email us with a few details of the site.
Is Sonning Common within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
How often do AHUs need cleaning?
That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
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.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where necessary.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
About our AHU cleaning in Sonning Common
If the units serving a building in Sonning Common have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. If you are dealing with units that have only ever had filter changes and stale or musty smells from the ventilation, we can put it right.
In a place like Sonning Common, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
A written report with photos follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards
After the visit, a few habits help the work last:
- Keep inspection doors on the unit in good order
- Change filters on schedule and log each change
- Clear leaves and litter away from the intake
- Store the TR19 paperwork where auditors can find it
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Part by part
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
When something else is needed
To be straight with you, there are a few things this work will not fix:
- The supply and extract ducts, quoted separately
- Ventilation that was badly designed in the first place
- Mechanical faults with motors, belts or bearings
Not sure which it is? You can call 0345 646 2711, or send details by email and we will tell you honestly.
Parts of the system we cover
- Internal panels
- Dampers and louvres

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.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Landlords, agents and facilities managers
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.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.

What we do, step by step
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes half a day to a full day per unit, with large plant planned over several shifts, and the area is cleaned down before we leave. Getting to the system matters more than parking in a place like Sonning Common, so let us know how to reach it.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Find the previous report, if there is one
- Tell us where we can park and unload
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Getting a quote

Advice
What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. It’s easy to lose track of when the work was last done on a quieter site.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before any work starts.
