Ventilation in East Wickham buildings
Going by the FSA’s register, there are about 32 schools, colleges and universities and about 62 hospitals, care homes and childcare premises serving food in East Wickham 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. East Wickham’s nearest hospital, Memorial Hospital, is about 1.3 miles west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
If you run a surgery, dental practice or care home near East Wickham, clean ventilation matters as much to you as to a hospital like Memorial Hospital (about 1.3 miles west). For workplaces around Welling station with mechanical ventilation, cleaning can be done in the evening or at weekends.

About our AHU cleaning in East Wickham
Where a building in East Wickham has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. Common call-outs are for air handling units with blocked filters and condensate trays that won’t empty, on heating and cooling coils, internal panels and filter sections.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in East Wickham.
The paperwork matters as much as the work. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. A busy site in East Wickham builds up dirt and wear quickly, so putting it off makes the eventual job larger.
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or email us, and we will explain what it covers.

Part by part
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.

Questions from East Wickham
Do you work at weekends in East Wickham?
Yes, evening, overnight and weekend work is normal for us. The work in East Wickham can fit around your hours. Let us know the hours you are closed and we’ll book within them.
Do you do school ventilation cleaning in East Wickham in the summer holidays?
Yes, holiday work suits schools best. Around East Wickham, the Food Standards Agency lists about 32 schools and colleges with registered kitchens within a mile and a half or so. Just ring 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Every site has its own report.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
How often do AHUs need cleaning?
That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
Do you have insurance?
Yes. We are fully insured, and we can share the details when you need them.
Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Change filters on schedule and log each change
- Report water on the plant room floor
- Plan the next inspection before the last report gets filed away
- Report musty smells from the vents right away
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
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 happens on the day
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes half a day to a full day per unit, with large plant planned over several shifts, and the area is cleaned down before we leave. Loading bays, visitor permits and roof access are the first things we ask about for a site in East Wickham.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us about site rules, permits or sign-in
- Arrange a key holder or contact on site
Get a fixed quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Once you have those, phone us on 0345 646 2711 or send us an email.
Advice
What we are called out for in East Wickham
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
What we are most often called out for:
- Dust-coated heating and cooling coils
- Fan sections that haven’t been cleaned in years
- Rooms that smell stuffy when the system runs
- Blocked condensate drains and slimy trays
For schools like East Wickham Primary Academy, the holidays are the usual time to inspect and clean ventilation.

Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
