About our AHU cleaning in Orsett Heath
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you’re dealing with rooms that smell stuffy when the system runs and units that have only ever had filter changes, we can put it right, from dampers and louvres, internal panels and supply and extract fans onwards.
Work in a small place like Orsett Heath 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, with full insurance on top.

How the visit works
A visit follows the same order every time: protect the area, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. The visit itself takes from a few hours for a compact unit to a day or more for a large one. If the van will struggle with a lane or gateway near Orsett Heath, let us know and we will plan around it.
- We look at the unit and the plant area during the survey.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Move anything stored near the system
- Tell us about site rules, permits or sign-in

Related advice
Do you need AHU cleaning in Orsett Heath?
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that’s the air they breathe for hours on end.
Clients normally contact us when they notice something like this:
- Dust built up on fan impellers
- Air handling units never cleaned inside
- Odours coming through the supply air
- Filters that are clogged or overdue
If you manage a school such as Treetops School, ventilation cleaning is best booked for the holidays.

Why act early in Orsett Heath
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. It’s worth booking a check, because nobody sees inside a duct day to day.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.

Take a look at how cleaning jobs are priced and how to check a contractor.
How we price AHU cleaning
A fixed price needs a few facts first. We look at:
- The condition of the system
- Where the site is and how we reach it
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, call us on 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Wide pictures of the system and the area around it
- Problems your staff have spotted
- The site address and the type of premises
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, phone us on 0345 646 2711 or use the quote form with the site type, opening hours and a few photos.
Is there a report after cleaning?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
Do you do ventilation duct cleaning too?
Yes. We reach the ducts through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where necessary.
What about areas you can’t get to?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.
When should our AHU next be cleaned?
That’s set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

In-house cleaning or a specialist?
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
