- Plant that needs cleaning after a refit
- Drain trays holding standing water
- Dirty fans and fan housings
Keeping the system healthy
To keep the system working properly between visits:
- Plan the next inspection before the last report gets filed away
- Keep filter changes on time and recorded
- Watch for drips or damp patches near the plant
- Make sure condensate is draining away
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
AHU cleaning for kitchens and businesses in Standon
If the units serving a building in Standon have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. The work covers heating and cooling coils, drain trays and filter sections, and people most often call us about intake sections clogged with outdoor debris and filters that are clogged or overdue.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

What affects the cost of AHU cleaning
The diagnosis comes before the price. The main factors are:
- Site rules, permits and inductions
- The condition we find in the survey
- Whether we need access equipment or extra panels
- Parking and loading at the site
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- The times we could work without disrupting the site
- A few general shots of the system
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your last certificate, test record or report
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, phone us on 0345 646 2711, or email photos.
What AHU cleaning can’t fix
To be straight with you, some problems need a different fix:
- Dirty ducts beyond the unit itself
- Breakdowns that need a mechanical engineer
- A system that’s undersized for the building
If you’re not sure, just give us a ring on 0345 646 2711 or send us an email and we’ll give you a straight answer before booking.

What we’re called out for in Standon
Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Any of these means the system needs a check-up:
- Units that have only ever had filter changes
- Dust-coated heating and cooling coils
- Plant that needs cleaning after a refit
- Dirty fans and fan housings
For schools like Roger De Clare First CofE School, the holidays are the usual time to inspect and clean ventilation.

Standon: your questions answered
Can the work in Standon be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. It means the site in Standon keeps running as normal. Just phone us on 0345 646 2711, or email photos with your opening times and we’ll plan around them.
Can you get to a site in Standon?
Yes, Standon is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Can you price the work without visiting?
Yes, where the photos show enough. If not, a site survey comes first, then a fixed quote.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What about areas you can’t get to?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Do you need to switch the unit off?
Yes, for the time we are working on it. Out-of-hours work is available to keep disruption down.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Are you accredited?

How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. Visits to a village like Standon are booked in advance, at a time that suits whoever runs the site.
- We agree a shutdown window that suits the building.
- 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.
- We take after photos and issue the certificate and report.
How to prepare
- Let us know about permits to work or site inductions
- Plan for cooking equipment or plant to be off before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms

What the work involves, part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
