About our AHU cleaning in Stroud Green
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. The work covers drain trays, supply and extract fans and internal panels, and the jobs we see most are debris and leaves in the fresh air intake and dirty coils holding back the airflow.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. In Stroud Green, as elsewhere, cleaning starts with an inspection of what’s there.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Your questions about AHU cleaning in Stroud Green
Can you work in Stroud Green outside opening hours?
Yes, we can come after you close and finish before you open. The work in Stroud Green can fit around your hours. Your opening times are the first thing we ask for.
Can ventilation in schools around Stroud Green be cleaned out of term?
Yes, holiday work suits schools best. There are about 41 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Stroud Green. You can call 0345 646 2711, or email photos with the dates the site is empty.
Is Stroud Green in your area?
Yes. Stroud Green is part of the area we cover, as part of our area across London and the South East.
What does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What happens if you cannot reach some of it?
Anything we cannot reach goes on the report, with pictures where possible, and we explain what access is needed, such as extra access panels in ductwork.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Do you need to switch the unit off?
Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building is not left without ventilation when it’s busy.
Managing agents and facilities teams in Stroud Green
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.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.

What else we do in Stroud Green
How we price AHU cleaning
The survey tells us what the work involves. The main factors are:
- Where the site is and how we reach it
- Whether several sites go on one quote
- A single visit or a regular plan
- Whether we need access equipment or extra panels
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before work begins.
What we need to know
You don’t need the technical terms. It helps if you can send:
- The site address and the type of premises
- Problems your staff have spotted
- Any previous report or certificate
- Your opening hours and when the area is out of use
Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
What the work involves, part by part
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with pictures so you can decide on any repairs.
What we are called out for in Stroud Green
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
Look out for any of the following:
- Rooms that smell stuffy when the system runs
- Drain trays holding standing water
- Units needing a clean before a new tenant or handover
- Leaves and litter drawn into the unit
If you manage offices or shops near Harringay station, their ventilation can be inspected and cleaned out of hours.
What your quote should include
- Whether a written report and photos are included
- How areas they cannot reach will be recorded
- Whether they recommend a next date
- Whether the work can be done while the site is closed
What we do, step by step
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a single shift for a typical unit, longer for large or heavily soiled ones. Getting kit into a London building takes planning, so let us know where we can load and park in Stroud Green.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Tell us where we can park and unload
- Move anything stored near the system
How to get a quote
Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Once you have those, ring 0345 646 2711 or send us an email.

- Heating and cooling coils

Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Diary the inspection date recommended in the report
- Watch for drips or damp patches near the plant
- Report stiff or damaged access doors
- File each AHU report in the maintenance log
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
