AHU cleaning for kitchens and businesses in South Weston
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 are dealing with intake sections clogged with outdoor debris and air handling units never cleaned inside, we can put it right.
Work in a small place like South Weston starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Common questions in South Weston
Will you come out to South Weston?
Yes. South Weston is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Do you work at weekends in South Weston?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Your opening times are the first thing we ask for.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
What if parts of the system can’t be reached?
Anything we can’t reach goes on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
Will the ventilation be off while you clean?
Yes. We can’t clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We don’t leave it behind.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.

What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- Site requirements such as sign-in and permits
- Whether we need access equipment or extra panels
- Parking and loading at the site
- Whether several sites go on one quote
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.
Asking for a quote
To help us quote quickly, please include:
- How we’d reach plant on a roof or in a plant room
- The paperwork from the last visit, if you have it
- Where the site is and what kind of site it is
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Need a price for AHU cleaning? Please phone us on 0345 646 2711, or send details by email and tell us about the site. We’ll talk you through the work and send you a fixed quote before you commit to anything.
Multi-site and managed buildings
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Common problems we fix in South Weston
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
Clients normally contact us after spotting one of these:
- Odours coming through the supply air
- Units needing a clean before a new tenant or handover
- Drain trays holding standing water
- Dirty fans and fan housings
Thame Community Hospital, about 4.6 miles north, is the nearest hospital to South Weston, and healthcare sites of every size need their supply air kept clean.
Before you book anyone
- Proof of insurance
- What happens if part of the system can’t be accessed
- If the quote is a fixed price or an estimate
- How VAT is shown on the quote
What happens on the day
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It 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. For a village or hamlet like South Weston, tell us about narrow lanes, gates and parking when you book.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Have your last certificate or report to hand
- Let us know about permits to work or site inductions
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- File each AHU report in the maintenance log
- Book the next check in line with the report
- Report water on the plant room floor
- Stick to the filter change plan
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.

What happens if it’s left?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. In a small place like South Weston, a system that fails can take a site out of use.
What you pay depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.
