AHU cleaning in Ockley
Our AHU cleaning covers sites in Ockley and the rest of Surrey, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you have plant that has been serviced but not cleaned and dirty coils holding back the airflow, we can put it right.
Work in a small place like Ockley starts with agreeing access and timings.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Don’t ignore odours coming through the grilles
- Make sure the unit’s access doors open easily
- Check the drain tray is emptying during routine visits
- Watch for drips or damp patches near the plant
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Why deal with it now?
Stuffy rooms and stale smells in a building in Ockley can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. In a small place like Ockley, a system that fails can take a site out of use.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.
Why us?
- Out-of-hours work and a 24/7 emergency line

Questions from Ockley
Can you come to Ockley after we close?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Ockley needn’t be disturbed. Just call 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Is Ockley within the area you cover?
Yes, we work in villages as well as towns, and Ockley is covered. Just mention lanes, gates or anything else about the site when you book.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
How much notice should we give?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
How long does it take to clean an air handling unit?
Cleaning takes one overnight shift for many single units, with bigger plant phased. Bigger units can be phased, so give us a ring on 0345 646 2711 or drop us a line to talk it through.
Do you clean the ductwork as well?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where needed.
When to call us in Ockley
Whatever surrounds a building in Ockley, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Look out for any of the following:
- Coils clogged with dust and debris
- Condensate trays that will not empty
- Units that have only ever had filter changes
- Odours coming through the supply air
If you run a surgery, dental practice or care home near Ockley, clean ventilation matters as much to you as to a hospital like Horsham Hospital (about 5.5 miles south).
Before you book anyone
- Whether the work can be done while the site is closed
- Proof of insurance
- What paperwork you get at the end
- What happens if part of the system can’t be accessed

What else we do in Ockley
How the job changes from site to site
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey so the quote reflects it.
How it works
On the day, we arrive 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 the area around the work is covered and protected. On site, it takes half a day to a full day per unit, with large plant planned over several shifts. A quick note on how to find the site and where to park makes a visit to Ockley run smoothly.
- 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 pictures and issue the certificate and report.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand

What affects the cost of AHU cleaning
The survey tells us what the work involves. The main factors are:
- Any permits to work or inductions
- Whether it’s a one-off visit or part of a schedule
- How big the system is
- Whether several sites go on one quote
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.
What to send for a quote
You do not need the technical terms. It helps if you can send:
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
To help us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711 or drop us a line.
