About our AHU cleaning in Nazeing
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. We are often asked to deal with stale or musty smells from the ventilation and dust-coated heating and cooling coils, across drain trays, filter sections and internal panels.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Honest limits
AHU cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- Building management system faults
- Faulty motors, drives or bearings
- The supply and extract ducts, quoted separately
If you are not sure, just ring 0345 646 2711 or drop us a line and we’ll give you a straight answer before booking.
Parts of the system we cover
- Internal panels
- Heating and cooling coils
- Supply and extract fans
- Drain trays
- Filter sections
- Dampers and louvres
For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
How we price AHU cleaning
Sites vary more than people expect. What affects the quote:
- One-off work versus a regular cycle
- Site rules, permits and inductions
- The number of sites or systems
- The size of the system
What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before work begins, so there are no surprises.
Helping us quote
When you contact us, these details help:
- Where the site is and what kind of site it is
- Your last certificate, test record or report
- Problems your staff have spotted
- How we’d reach plant on a roof or in a plant room
To get a fixed quote, give us a ring on 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
What happens on the day
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 before work begins, 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. For a village or hamlet like Nazeing, tell us about narrow lanes, gates and parking when you book.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any parking or loading restrictions
- Tell us the best time to work, such as after service or at a weekend

We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, phone us on 0345 646 2711 or email us.

What information do you need?

What happens if it’s left?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. If the system at a site near Nazeing fails, there may be nowhere nearby to move to.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before any work starts.
What you get with us
- Full insurance on every job
- A written report with pictures after every visit
- Out-of-hours work and a 24/7 emergency line
- One contact for all your sites in London and the South East

When to call us in Nazeing
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
If you notice any of these, it’s worth a diagnosis:
- Filters that are clogged or overdue
- Dust built up on fan impellers
- Condensate trays that will not empty
- Leaves and litter drawn into the unit
If you manage a school such as Water Lane Primary Academy, ventilation cleaning is best booked for the holidays.
Questions to ask before you book
- What hours they’ll be on site
- Whether the whole system is included, or only the parts that are easy to reach
- Whether they recommend a next date
- If the quote is a fixed price or an estimate
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Change filters on schedule and log each change
- Note any water around the unit or leaks below it
- Look at the condensate drain whenever the unit is serviced
- Flag stale or damp smells in the supply air
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
