AHU cleaning in Woodhatch, done properly
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from photos or a site visit, and give you a fixed quote before any cleaning starts. If you’re dealing with stale or musty smells from the ventilation and leaves and litter drawn into the unit, we can help.
For a building in or near Woodhatch, access is agreed in advance and the visit is planned around the journey.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What the work involves, part by part
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
What we’re called out for in Woodhatch
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that’s the air they breathe for hours on end.
It’s time to book a visit if you see:
- Air handling units due a clean after building work
- Air handling units never cleaned inside
- Intake sections clogged with outdoor debris
- Air handling units with blocked filters
An inspection comes first for any ventilation job around Woodhatch, so the cleaning matches what’s there.

What affects the cost of AHU cleaning
We do not publish a price list, because sites vary so much. The quote depends on:
- Travel, parking and unloading
- How many systems or sites are involved
- When the work can happen, such as evenings, overnight or weekends
- The scale of the work
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and the price is agreed before any work starts.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
- Problems your staff have spotted
- A few general shots of the system
For AHU cleaning in Woodhatch, phone us on 0345 646 2711 or send us an email. Let us know the site type and the opening hours, and send pictures or your last report if you can. A fixed quote usually follows within one working day.
How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes half a day to a full day per unit, with large plant planned over several shifts, and we clear up before we go. The timing of a visit to Woodhatch is set by you, and the travel is our side of the planning.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos 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.
- We take after photos and issue the certificate and report.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Tell us where we can park and unload
- Let us know how we reach the system, including roofs, risers and plant rooms
Getting a quote
Quotes are quick. Send a few details and pictures, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Advice

What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Keep the area around the fresh air intake clear
- File each AHU report in the maintenance log
- Do not ignore odours coming through the grilles
- Make sure the unit’s access doors open easily
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
Woodhatch questions

Yes. We work evenings, overnight and at weekends. It means the site in Woodhatch keeps running as normal. Tell us your opening hours when you ask for a quote.

Yes. Our area runs across London and the South East, Woodhatch included. You can ring 0345 646 2711 or send us an email and let us know what needs doing.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.

Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What about areas you can’t get to?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
Do you repair air handling units?
The clean includes noting faults, but repairs sit with your maintenance contractor, with pictures where it helps.
