South Chingford: your questions answered
How do you handle parking and loading in South Chingford?
A loading bay, a visitor permit or off-street space near the site in South Chingford makes the visit easier to plan. Working overnight, as we often do in London, normally makes it simpler.
Can the work in South Chingford be done at night or at weekends?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Just call us on 0345 646 2711 or drop us a line with your opening times and we will plan around them.
Do you have insurance?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
What do you do with what you remove?
We take it away at the end of the visit. During the work, it’s contained to keep the area clean.
Does the AHU have to be shut down for cleaning?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
What do you clean inside the unit?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
About our AHU cleaning in South Chingford
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. Typical jobs include units that have only ever had filter changes and drain trays holding standing water, on supply and extract fans, heating and cooling coils and filter sections.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in South Chingford, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Keeping the system healthy
Results last longer with the right care. We suggest:
- Keep filter changes on time and recorded
- Plan the next inspection before the last report gets filed away
- Keep the certificate and photo report with the plant records
- Report musty smells from the vents right away
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
When to call us in South Chingford
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
If you notice any of these, it’s worth a diagnosis:
- Blocked condensate drains and slimy trays
- Air handling units due a clean after building work
- Debris and leaves in the fresh air intake
- Stale or musty smells from the ventilation
Healthcare buildings such as North Middlesex University Hospital, about 2.1 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near South Chingford, yours matters too.

What the work involves, part by part
Drain trays
Older trays can corrode and start leaking. We record their condition with pictures so repairs can be planned.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
What staff can safely do
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Landlords, agents and facilities managers
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.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.

How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes from a few hours for a compact unit to a day or more for a large one, and the area is cleaned down before we leave. In South Chingford, as across London, we normally work overnight or at weekends and hand the site back ready to open.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Agree a time when the area can be out of use
- Mention any locked doors, roof access or ceiling voids
- Clear the space around the work
