How we price AHU cleaning
The survey tells us what the work involves. We look at:
- How easy every part is to reach
- One-off work versus a regular cycle
- The number of sites or systems
- The condition we find in the survey
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.
Helping us quote

- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Where the site is and what kind of site it is

AHU cleaning in Great Hollands, done properly
Our AHU cleans for sites in Great Hollands cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers drain trays, supply and extract fans and dampers and louvres, and common reasons people get in touch are condensate trays that won’t empty and plant that needs cleaning after a refit.
Smaller buildings around Great Hollands often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Report stiff or damaged access doors
- Clear leaves and litter away from the intake
- Do not ignore odours coming through the grilles
- Stick to the filter change plan
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
Managing agents and facilities teams in Great Hollands
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
The process
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes one overnight shift for many single units, with bigger plant phased. For a site near Great Hollands, the work is booked around your opening hours, evenings and weekends included.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Find the previous report, if there is one
- Clear loose items from the work area

What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
How often should an air handling unit be cleaned?

Earlier is better, especially for out-of-hours work. Quotes typically come back within one working day, and emergencies are covered by our 24/7 line.

BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
When to call us in Great Hollands
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Clients typically contact us after spotting one of these:
- Plant that has been serviced but not cleaned
- Stale or musty smells from the ventilation
- Debris and leaves in the fresh air intake
- Blocked condensate drains and slimy trays
If you manage a school such as Great Hollands Primary School, ventilation cleaning is best booked for the holidays.
Before booking anyone
- Proof of accreditation you can verify
- How areas they cannot reach will be recorded
- Whether the quote is based on a survey or pictures
- How VAT is shown on the quote
What your team can do, and what needs us
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
When it’s something else
It’s worth knowing the limits before booking:
- Airflow problems caused by the system’s design
- Coils that are corroded or leaking and need replacing
- Mechanical faults with motors, belts or bearings
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we’ll tell you honestly before booking.
