AHU cleaning for kitchens and businesses in Middle Wallop
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you’re dealing with odours coming through the supply air and plant that has been serviced but not cleaned, we can put it right, from internal panels, dampers and louvres and heating and cooling coils onwards.
Somewhere as small as Middle Wallop, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Good records are part of the job. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Honest limits
To be straight with you, some problems need a different fix:
- Coils that are corroded or leaking and need replacing
- Ductwork downstream of the unit, which is a separate clean
- Breakdowns that need a mechanical engineer
Not sure which it is? You can call 0345 646 2711 or drop us a line and we will tell you honestly before you book.

Between visits
Simple habits between visits make a real difference. Our advice:
- File each AHU report in the maintenance log
- Note any water around the unit or leaks below it
- Make sure condensate is draining away
- Don’t store bins or materials near the intake
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. They belong in the plant or maintenance log.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.

What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
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.
The process
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near Middle Wallop, let us know and we will plan around it.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Arrange a key holder or contact on site
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know when the site is closed or quiet
Get a fixed quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Managing agents and facilities teams in Middle Wallop
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Different parts, different methods
Drain trays
Older trays can corrode and start leaking. We record their condition with photos so you can decide on any repairs.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.
Middle Wallop: your questions answered
Do you offer AHU cleaning in Middle Wallop?
Yes. Our area runs across London and the South East, Middle Wallop included. Get in touch with the details and we will arrange a survey.
Can you get to a site in Middle Wallop?
Yes. Middle Wallop 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.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
How long does it take to clean an air handling unit?
It takes anything from half a day for one small unit to several shifts for a plant room full of them. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Is a quote from photos possible?
Usually, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and we usually come back within one working day. Some sites still need a visit, and we will say so.
What do you do with what you remove?
It leaves the site with us when we go. While we work, it’s kept contained so the area stays clean.
Are you accredited?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
What affects the cost of AHU cleaning
Sites vary more than people expect. The main factors:
- The scale of the work
- The condition we find in the survey
- One-off work versus a regular cycle
- Access, including roofs, risers and ceiling voids
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 the price is fixed before we start.
Asking for a quote
When you contact us, these details help:
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
- Anything you’ve noticed, such as smells, noise, drips or poor airflow

Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Once you have those, ring 0345 646 2711, or email photos.
