AHU cleaning in Norcot
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you have dust built up on fan impellers and dust-coated heating and cooling coils, we can put it right, from heating and cooling coils, filter sections and supply and extract fans onwards.
Smaller buildings around Norcot often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
Every visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Signs you need AHU cleaning in Norcot
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
Common reasons sites call us are:
- Rooms that smell stuffy when the system runs
- Air handling units due a clean after building work
- Dirty coils holding back the airflow
- Dust built up on fan impellers
Classrooms and halls at schools such as Meadow Park Academy are easiest to work in when pupils are away.
Before booking anyone
- Whether a written report and photos are included
- If they look at the system before pricing
- If the quote is a fixed price or an estimate
- Whether the whole system is included, or only the parts that are easy to reach

What else we do in Norcot
What affects the quote in Norcot
The survey tells us what the work involves. The main factors are:
- The condition we find in the survey
- Whether we need access equipment or extra panels
- A single visit or a regular plan
- The scale of the work
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711, or send details by email, and we’ll explain what it covers.
Asking for a quote
Before you ask for a quote, gather:
- The roof, plant room or outside wall the system runs to
- A few general shots of the system
- When the site is open and when it’s quiet
- Detail shots of panels, filters and grilles
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Why deal with it now?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. It’s easy to lose track of when the work was last done on a quieter site.
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 give you a fixed price before work begins.
Why us?
- CHAS, SafeContractor and ISO 9001
- In business since 2009

FAQs for Norcot
Can you get to a site in Norcot?
Yes. Norcot is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Can the work in Norcot be done at night or at weekends?
Yes, we can come after you close and finish before you open. The work in Norcot can fit around your hours. Tell us your opening hours when you ask for a quote.
How long does it take to clean an air handling unit?
Cleaning takes half a day to a full day per unit, with large plant planned over several shifts. Bigger units can be phased, and you can call 0345 646 2711 or send us an email to plan it.
What is 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 often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What should I send you?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then call 0345 646 2711, or email photos.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, usually ready within one working day.
What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes half a day to a full day per unit, with large plant planned over several shifts. For a place like Norcot, we load the van from the survey notes so the work can be done in one visit where possible.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Find the previous report, if there is one
- Name a contact who can let us in at the agreed time
Get a fixed quote
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, you get a fixed price before we start.
Advice
When something else is needed
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It does not solve:
- Problems with the unit’s controls or sensors
- Ventilation that was badly designed in the first place
- The supply and extract ducts, quoted separately
If in doubt, call 0345 646 2711 or email us and we will say what we think before booking.
Parts of the system we cover
- Heating and cooling coils
- Supply and extract fans
- Internal panels
- Drain trays
- Filter sections
- Dampers and louvres
In-house cleaning or a specialist?
A few tasks are always specialist work: 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.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Keep the certificate and photo report with the plant records
- Clear leaves and litter away from the intake
- Report musty smells from the vents right away
- Watch for drips or damp patches near the plant
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
