About our AHU cleaning in Thakeham
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. The work covers filter sections, internal panels and supply and extract fans, and people most often call us about drain trays holding standing water and units needing a clean before a new tenant or handover.
In a village or hamlet like Thakeham, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Landlords, agents and facilities managers
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
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.
Your questions about AHU cleaning in Thakeham
Will you come out to Thakeham?
Yes, Thakeham is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
Can you work in Thakeham outside opening hours?
Yes, out-of-hours work is a big part of what we do. It means the site in Thakeham keeps running as normal. Your opening times are the first thing we ask for.
Is there a survey before the work?
Yes. Every job is surveyed first, from your photos and details, or with a visit where necessary. Then you get a fixed quote.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Each site gets its own report and photos.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after pictures. They’re worth keeping with the plant records.
Why it’s worth doing now in Thakeham
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. If the system at a site near Thakeham fails, there may be nowhere nearby to move to.
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before any work starts.

Common problems we fix in Thakeham
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
Look out for any of the following:
- Dirty filters cutting the airflow
- Air handling units never cleaned inside
- Intake sections clogged with outdoor debris
- Dust built up on fan impellers
An inspection comes first for any ventilation job around Thakeham, so the cleaning matches what’s there.
Questions to ask before booking
- How VAT is shown on the quote
- What paperwork you get at the end
- Whether the price is fixed
- What’s included in the scope, part by part
How the visit works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a single shift for a typical unit, longer for large or heavily soiled ones. We agree a date with you, plan the drive to Thakeham and turn up when the site is quiet.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Arrange a key holder or contact on site
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use

What a clean will not put right
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Controls and BMS settings that run the unit
- A system that’s undersized for the building
- Dirty ducts beyond the unit itself
Not sure which it is? You can give us a ring on 0345 646 2711 or drop us a line and we will tell you honestly.

Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Make sure the unit’s access doors open easily
- Note any water around the unit or leaks below it
- Clear leaves and litter away from the intake
- Check the drain tray is emptying during routine visits
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
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 will take a look and send you a fixed quote.
