AHU cleaning for kitchens and businesses in Donkey Street
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and give you a fixed quote, so you know where you stand. We’re often asked to deal with units needing a clean before a new tenant or handover and blocked condensate drains and slimy trays, across supply and extract fans, heating and cooling coils and filter sections.
Work in a small place like Donkey Street starts with agreeing access and timings.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Looking after it afterwards
After the visit, a few habits help the work last:
- Check the drain tray is emptying during routine visits
- Report water on the plant room floor
- Plan the next inspection before the last report gets filed away
- Store the TR19 paperwork where auditors can find it
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 make sure it stays clear.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
How the job changes from site to site
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
How it works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before we start, and the area around the work is covered and protected. The work itself takes half a day to a full day per unit, with large plant planned over several shifts. For a village or hamlet like Donkey Street, tell us about narrow lanes, gates and parking when you book.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Tell us where we can park and unload
- Have your last certificate or report to hand
- Make sure equipment near the work can be switched off and left to cool
Getting a quote
Quotes are quick. Send a few details and photos, 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.

Why deal with it now?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Systems in rural buildings are often out of sight and out of mind.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

How we price AHU cleaning
Your quote is based on your site. We consider:
- What state the system is in
- How many systems or sites are involved
- Working hours and out-of-hours timing
- Any permits to work or inductions
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or email us, and we will explain what it covers.
Asking for a quote
Before you ask for a quote, gather:
- Your opening hours and when the area is out of use
- Wide photos of the system and the area around it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

Can you look after several sites?

Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
Are you insured?
Yes, we’re fully insured. We also hold CHAS and SafeContractor, for sites that check contractor safety.
How long will the unit be out of action?
Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Large plant can be split over several shifts, and you can phone us on 0345 646 2711 or email us to plan it.
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Do you need AHU cleaning in Donkey Street?
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Any of these means the system needs a check-up:
- Intake sections clogged with outdoor debris
- Stale or musty smells from the ventilation
- Dust built up on fan impellers
- Filters that are clogged or overdue
In Donkey Street, we look inside the system before deciding what needs cleaning.
