Common questions in Chelsea Harbour
What do you need to know about parking in Chelsea Harbour?
A loading bay, a visitor permit or off-street space near the site in Chelsea Harbour makes the visit easier to plan. If the building has a loading slot system, we’ll book into it.
Do you work overnight in Chelsea Harbour?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Chelsea Harbour needn’t be disturbed. Just ring 0345 646 2711 or use the quote form with your opening times and we will plan around them.
What’s included in an AHU clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
What information do you need?
Only a few details: 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 send details by email.
How long does it take to clean an air handling unit?
As a guide, it takes a single shift for a typical unit, longer for large or heavily soiled ones. The shutdown is planned to fit, out of hours if needed.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Are you insured?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
AHU cleaning in Chelsea Harbour
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. We’re often asked to deal with plant that has been serviced but not cleaned and debris and leaves in the fresh air intake, across filter sections, internal panels and drain trays.
London buildings tend to keep their plant on the roof or below ground, so work in Chelsea Harbour is often done in the evening or at weekends. Loading and parking are planned with the building first.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What happens on the day
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and hand over the paperwork. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Before any visit in Chelsea Harbour, we agree where the van can stop and how equipment reaches the system.
- 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.

What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
What the work involves, part by part
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
How we price AHU cleaning
Your quote is based on your site. We consider:
- Whether it’s a one-off visit or part of a schedule
- Whether several sites go on one quote
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
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. Call for a fixed quote and we’ll go through it with you.
Helping us quote
To speed up the quote, send us:
- The postcode and the type of business
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- The times we could work without disrupting the site
Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Then ring 0345 646 2711, or email photos.
Signs you need AHU cleaning in Chelsea Harbour
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Clients normally contact us after spotting one of these:
- Air handling units due a clean after building work
- Air handling units never cleaned inside
- Filters that are clogged or overdue
- Rooms that smell stuffy when the system runs
If you run a surgery, dental practice or care home near Chelsea Harbour, clean ventilation matters as much to you as to a hospital like Chelsea and Westminster Hospital (about 0.6 miles north).

Ventilation in Chelsea Harbour buildings
Food Standards Agency data includes about 58 schools, colleges and universities, about 79 caring premises (care homes, nurseries and hospitals) and about 48 hotels and B&Bs in Chelsea Harbour and the streets around it, up to about 1.5 miles out. Busy, occupied buildings like these are where clean supply air matters most. For Chelsea Harbour, the closest hospital is Chelsea and Westminster Hospital, roughly 0.6 miles north. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Ventilation cleaning in London buildings is usually planned for evenings or weekends.
If you run an office near Imperial Wharf station, its supply ductwork can gather dust for years before anyone looks inside. Wherever a school like Chelsea Academy has ducted ventilation, a half-term visit keeps the work out of lesson time.

Leave it or put it right?
Stuffy rooms and stale smells in a building in Chelsea Harbour can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. In Chelsea Harbour, as across London, ductwork often passes through shared risers and other people’s space.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before any work starts.

Looking after it afterwards
Once we have finished, these simple steps help:
- Change filters on schedule and log each change
- Look at the condensate drain whenever the unit is serviced
- Note any water around the unit or leaks below it
- Clear leaves and litter away from the intake
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
