Common questions in Wood Green
Do you do school ventilation cleaning in Wood Green in the summer holidays?
Yes, and it’s the easiest time to do it. Around Wood Green, the Food Standards Agency lists about 49 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Can parking be tricky for a job in Wood Green?
Tell us where a van can stop near your site in Wood Green, and about any building rules on loading. If the building has a loading slot system, we will book into it.
What if parts of the system cannot be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
Where does the waste go?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
AHU cleaning in Wood Green, done properly
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. The work covers dampers and louvres, supply and extract fans and internal panels, and people most often call us about fan sections that haven’t been cleaned in years and leaves and litter drawn into the unit.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Wood Green, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
What AHU cleaning looks like in Wood Green
Going by the FSA’s register, there are about 49 schools, colleges and universities and about 56 care, childcare and hospital premises serving food within about 1.5 miles of central Wood Green. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. For Wood Green, the closest hospital is Greentrees Hospital, roughly 0.9 miles north-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
School buildings such as St Michael's CofE Primary School are typically done in the holidays, so classrooms aren’t disturbed. Hospitals such as Greentrees Hospital (about 0.9 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Wood Green are no different.

What the work involves, part by part
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.

What we are called out for in Wood Green
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
Clients typically contact us when they notice one of these:
- Debris and leaves in the fresh air intake
- Filters that are clogged or overdue
- Blocked condensate drains and slimy trays
- Dirty fans and fan housings
If you manage offices or shops near Alexandra Palace station, their ventilation can be inspected and cleaned out of hours.
What your quote should include
- Whether the quote shows VAT
- Whether the work can be done while the site is closed
- Whether a survey comes first
- Whether the whole system is included, or only the parts that are easy to reach
Landlords, agents and facilities managers
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Keep the certificate and photo report with the plant records
- Stick to the filter change plan
- Do not store bins or materials near the intake
- Report musty smells from the vents straight away
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.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
How it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes from a few hours for a compact unit to a day or more for a large one. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Wood Green.
- 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.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about permits to work or site inductions
