AHU cleaning in Hackney Marshes
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. Typical jobs include coils clogged with dust and debris and fan sections that haven’t been cleaned in years, on drain trays, supply and extract fans and dampers and louvres.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Hackney Marshes, dust settles in the units and ducts year after year.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Different parts, different methods
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
The process
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes one overnight shift for many single units, with bigger plant phased. We fit London jobs around the building rather than the other way round, so a visit in Hackney Marshes is typically out of hours.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Clear loose items from the work area
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool
Getting a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
FAQs for Hackney Marshes
Can ventilation in schools around Hackney Marshes be cleaned out of term?
Yes, out-of-term visits are normal for schools. There are about 31 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Hackney Marshes. Just phone us on 0345 646 2711 or email us with your term dates and we’ll plan around them.
Can you come to Hackney Marshes after we close?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Hackney Marshes needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
Do you have insurance?
Yes. We are fully insured, and we can share the details when you need them.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
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. After that, simply call 0345 646 2711 or use the quote form.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where needed.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Between visits
Once we have finished, these simple steps help:
- Make sure condensate is draining away
- Clear leaves and litter away from the intake
- Book the next check in line with the report
- Keep inspection doors on the unit in good order
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
What affects the quote in Hackney Marshes
The quote reflects the site in front of us. We consider:
- A single visit or a regular plan
- When the work can happen, such as evenings, overnight or weekends
- The number of sites or systems
- Parking and loading at the site
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.
Asking for a quote
When you call or email, these details help:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The postcode and the type of business
- Your last certificate, test record or report
- A few general shots of the system
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.
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. Clearing it now is a much smaller job. A building in Hackney Marshes may have flats or offices above and alongside, and a fault in the system can affect them too.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, give us a ring on 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.
