AHU cleaning in Lower Nazeing, done properly
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and send you a fixed quote before any cleaning starts. We are often asked to deal with debris and leaves in the fresh air intake and fan sections that haven’t been cleaned in years, on drain trays, filter sections and internal panels.
Visits to a place like Lower Nazeing are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across Essex. Larger estates can be phased building by building around the people who use them.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Lower Nazeing questions
Do you do school ventilation cleaning in Lower Nazeing in the summer holidays?
Yes, and it’s the easiest time to do it. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Lower Nazeing, it pays to plan holiday dates ahead. Send us your term dates when you phone us on 0345 646 2711, or send details by email, and we’ll fit the work in.
Do you work in villages like Lower Nazeing?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Will we get paperwork for the AHU clean?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
How long does it take to clean an air handling unit?
Typically the clean takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the shutdown around that, including evenings or weekends.
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Book the next check in line with the report
- Flag stale or damp smells in the supply air
- Check the drain tray is emptying during routine visits
- File each AHU report in the maintenance log
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What happens if it’s left?
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Around Lower Nazeing, a kitchen or building out of action is missed straight away.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before any work starts.
What you get with us
- A fixed price before any work starts
- Out-of-hours work and a 24/7 emergency line
- We’re fully insured
- A single point of contact for sites across the South East and London

Lower Nazeing buildings and their air
There are about 3 care, childcare and hospital premises on the FSA’s food hygiene register within about 1.5 miles of central Lower Nazeing. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Lower Nazeing’s nearest hospital, Princess Alexandra Hospital, is about 3.7 miles north-east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. About 17 miles out from central London, Lower Nazeing is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
Princess Alexandra Hospital, about 3.7 miles north-east, is the nearest hospital to Lower Nazeing, and healthcare sites of every size need their supply air kept clean. If you manage a school such as Nazeing Primary School, ventilation cleaning is best booked for the holidays.

How it works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes from a few hours for a compact unit to a day or more for a large one. Tell us about any gates, ladders or locked plant areas at your site near Lower Nazeing when you book.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures 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.
