What affects the cost of AHU cleaning
Every site gets its own quote. This is what makes a difference:
- Working hours and out-of-hours timing
- Site requirements such as sign-in and permits
- Where the site is and how we reach it
- How easy every part is to reach
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before work begins.
What to send for a quote
To speed up the quote, please include:
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
- How we’d reach plant on a roof or in a plant room
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.
AHU cleaning for kitchens and businesses in Woodrow
We clean air handling units for buildings in Woodrow and across Buckinghamshire, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. Common call-outs are for air handling units never cleaned inside and dirty coils holding back the airflow, on filter sections, internal panels and heating and cooling coils.
In a village or hamlet like Woodrow, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The paperwork matters as much as the work. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

The process
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Rural roads and tight entrances are worth telling us about before a visit to Woodrow.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Let us know about parking and loading
- Tell us about site rules, permits or sign-in

Your questions about AHU cleaning in Woodrow
Will you come out to Woodrow?
Yes, smaller places are covered as well as towns. A survey first, from photos or a visit, means we arrive with the right kit.
Is AHU cleaning available in Woodrow?
Yes. We work across London and the South East, and Woodrow is part of that. Get in touch with the details and we’ll arrange a survey.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Every site has its own report.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
How long will the unit be out of action?
The work takes one overnight shift for many single units, with bigger plant phased. Large plant can be split over several shifts, so give us a ring on 0345 646 2711, or send details by email to talk it through.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
What information do you need?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
When something else is needed
Before you book, it helps to know what’s not included:
- Mechanical faults with motors, belts or bearings
- Ductwork downstream of the unit, which is a separate clean
- Damaged coils beyond cleaning
Not sure which it is? You can call 0345 646 2711 or email us and we’ll tell you honestly.
What we work on in Woodrow
- Internal panels
- Supply and extract fans
- Filter sections
- Dampers and louvres
- Heating and cooling coils
- Drain trays
Looking after it afterwards
Once we have finished, these simple steps help:
- Don’t ignore odours coming through the grilles
- Store the TR19 paperwork where auditors can find it
- Look at the condensate drain whenever the unit is serviced
- Report stiff or damaged access doors
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Why it’s worth doing now in Woodrow
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Planning a trip to Woodrow ahead is easier for everyone than a rushed one.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

Different parts, different methods
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
