What affects the cost of AHU cleaning
Sites vary more than people expect. What affects the quote:
- How many systems or sites are involved
- Where the site is and how we reach it
- The condition we find in the survey
- When the work can happen, such as evenings, overnight or weekends
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- A few general shots of the system
- Any access panels or hatches you can see
- The times we could work without disrupting the site
- Any symptoms, from odd noises to smells or leaks
If you need AHU cleaning in Heyshott, call 0345 646 2711 or send us an email. Let us know the site type and the opening hours, and send photos or your last report if you can. A fixed quote normally follows within one working day.
About our AHU cleaning in Heyshott
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. The work covers supply and extract fans, dampers and louvres and internal panels, and people most often call us about plant that has been serviced but not cleaned and filters that are clogged or overdue.
For a building in or near Heyshott, access is agreed in advance and the visit is planned around the journey.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Why deal with it now?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, ready to show anyone who asks. Equipment tucked in a roof space or outbuilding near Heyshott rarely gets looked at unless someone books it.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before we start.

Questions from Heyshott
Can you come to Heyshott after we close?
Yes, we can come after you close and finish before you open. That way a site in Heyshott doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Do you work in villages like Heyshott?
Yes. Villages and rural sites across the South East are part of our work, Heyshott included. The journey is planned ahead, so a few details about the route help.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we will suggest an interval after the first clean.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. We typically quote within one working day, and there’s a 24/7 line for emergencies.
Can you set up regular visits?
Yes, of course. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.

What a clean will not put right
To be straight with you, there are a few things this work will not fix:
- Dirty ducts beyond the unit itself
- A system that’s undersized for the building
- Controls and BMS settings that run the unit

What the work involves, part by part
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Multi-site and managed buildings
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.

How the visit works
Every visit runs to the same pattern: protect the area, make the system safe, carry out the AHU cleaning, tidy up and leave you the report. On site, the work takes from a few hours for a compact unit to a day or more for a large one. In a small place like Heyshott, the journey is planned ahead and the visit arranged around the site’s hours.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Plan for cooking equipment or plant to be off before we arrive
- Mention any sign-in, permit or induction we need
How to get a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Advice
What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
