How we handle AHU cleaning in Ansteadbrook
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers filter sections, heating and cooling coils and dampers and louvres, and the jobs we see most are plant that has been serviced but not cleaned and fan sections that haven’t been cleaned in years.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with photos where it helps.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
How long does an AHU clean take?
Expect it to take half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.

Are you insured?

Will we get paperwork for the AHU clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
How it works
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. In a small place like Ansteadbrook, the journey is planned ahead and the visit arranged around the site’s hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Before we arrive
- Dig out any earlier paperwork for the system
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about permits to work or site inductions

Related advice
What affects the cost of AHU cleaning
The price is fixed before any work begins. It’s based on:
- What state the system is in
- Parking and loading at the site
- The number of sites or systems
- Working hours and out-of-hours timing
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.
What to send for a quote
To speed up the quote, send us:
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
- The times we could work without disrupting the site
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
Signs you need AHU cleaning in Ansteadbrook
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Clients normally contact us after spotting one of these:
- Filters that are clogged or overdue
- Units that have only ever had filter changes
- Air handling units due a clean after building work
- Condensate trays that will not empty
An inspection comes first for any ventilation job around Ansteadbrook, so the cleaning matches what’s there.

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.
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’ll take a look and give you a fixed quote.
What a clean won’t put right
A few issues sit outside what this work can do:
- Airflow problems caused by the system’s design
- Damaged coils beyond cleaning
- Ductwork downstream of the unit, which is a separate clean
If in doubt, ring 0345 646 2711 or email us and we will say what we think before you book.
Parts of the system we cover
- Filter sections
- Internal panels
- Dampers and louvres
- Drain trays
- Heating and cooling coils
- Supply and extract fans
Between visits
Aftercare is simple, and it helps at the next visit:
- Store the TR19 paperwork where auditors can find it
- Book the next check in line with the report
- Stick to the filter change plan
- Don’t store bins or materials near the intake
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
