How we handle AHU cleaning in Norbury
Our AHU cleans for sites in Norbury cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers heating and cooling coils, supply and extract fans and dampers and louvres, and the jobs we see most are units that have only ever had filter changes and blocked condensate drains and slimy trays.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Norbury, dust settles in the units and ducts year after year.
Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What staff can safely do
Staff cleaning and specialist work are not the same thing. 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.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
AHU cleaning in Norbury: local notes
There are about 30 schools, colleges and universities, about 130 hospitals, care homes and childcare premises and about 9 hotels and guest houses on the FSA’s food hygiene register in Norbury and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Croydon University Hospital is the nearest hospital, about 1.3 miles south of Norbury. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. In London, ventilation plant is often on the roof or below ground, so the work is normally done out of hours.
If you manage a school such as Kensington Avenue Primary School, ventilation cleaning is best booked for the holidays. If you run a surgery, dental practice or care home near Norbury, clean ventilation matters as much to you as to a hospital like Croydon University Hospital (about 1.3 miles south).

What affects the quote in Norbury
The survey tells us what the work involves. We look at:
- The condition of the system
- The scale of the work
- Travel, parking and unloading
- Working hours and out-of-hours timing
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before any work starts.
Helping us quote
When you call or email, it’s useful to have:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
For 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. You will typically have a quote within one working day.

Common problems we fix in Norbury
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.
Look out for these warning signs:
- Air handling units with blocked filters
- Blocked condensate drains and slimy trays
- Odours coming through the supply air
- Fan sections that haven’t been cleaned in years
If you run an office near Norbury station, its supply ductwork can gather dust for years before anyone looks inside.
What to look for in a quote
- How VAT is shown on the quote
- What happens if part of the system cannot be accessed
- Whether the figure could change on the day
- Which accreditations they hold, and whether you can check them
Leave it or put it right?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. Choosing the date yourself beats having a fault choose it for you.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
What you get with us
- Fully insured
- Ventilation hygiene specialists since 2009

Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Don’t store bins or materials near the intake
- Stick to the filter change plan
- Watch for drips or damp patches near the plant
- Look at the condensate drain whenever the unit is serviced
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
