About our AHU cleaning in Lower Clapton
An air handling unit is the heart of a building’s ventilation: 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. The work covers internal panels, drain trays and filter sections, and the jobs we see most are air handling units never cleaned inside and dirty fans and fan housings.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Lower Clapton is normally planned out of hours. Loading and parking are planned with the building first.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Different parts, different methods
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Do you need AHU cleaning in Lower Clapton?
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.

- Dust-coated heating and cooling coils
- Air handling units with blocked filters
- Dirty fans and fan housings
- Air handling units due a clean after building work

Lower Clapton buildings and their air
The FSA’s food hygiene register lists about 24 schools, colleges and universities, about 41 caring premises (care homes, nurseries and hospitals) and about 6 hotels, B&Bs and guest houses with registered kitchens or food service within 1.5 miles or so of the middle of Lower Clapton. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. Homerton University Hospital is the nearest hospital, about less than half a mile south of Lower Clapton. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
For schools like Rushmore Primary School, the holidays are the usual time to inspect and clean ventilation. For workplaces around Homerton station with mechanical ventilation, cleaning can be done in the evening or at weekends.

What happens on the day
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes from a few hours for a compact unit to a day or more for a large one. Most London sites cannot stop for the day, so work in Lower Clapton is typically done overnight, early in the morning or at weekends.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Getting ready for the visit

How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- One-off work versus a regular cycle
- The scale of the work
- Site requirements such as sign-in and permits
- Where the site is and how we reach it
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.
What to send for a quote
We can often survey from pictures. Try to include:
- Your last certificate, test record or report
- Wide photos of the system and the area around it
- The postcode and the type of business
- Your opening hours and when the area is out of use
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Managing agents and facilities teams in Lower Clapton
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.

Yes, evening, overnight and weekend work is normal for us. That way a site in Lower Clapton doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.

We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
What’s included in an AHU clean?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
Do you repair air handling units?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
Why it’s worth doing now in Lower Clapton

Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
