AHU cleaning for kitchens and businesses in Parsons Green
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after pictures in a report. If you are dealing with air handling units with blocked filters and dust-coated heating and cooling coils, we can put it right.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. In Parsons Green, as elsewhere, cleaning starts with an inspection of what’s there.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What else we do in Parsons Green
Common problems we fix in Parsons Green
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that is where slime and odours start.
Keep an eye out for any of the following:
- Blocked condensate drains and slimy trays
- Plant that has been serviced but not cleaned
- Odours coming through the supply air
- Plant that needs cleaning after a refit
If you run a surgery, dental practice or care home near Parsons Green, clean ventilation matters as much to you as to a hospital like Western Hospital (about 0.8 miles north).
Before booking anyone
- What happens if part of the system cannot be accessed
- Whether the quote is based on a survey or pictures
- Whether the whole system is included, or only the parts that are easy to reach
- Whether they recommend a next date
What your team can do, and what needs us
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.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
What AHU cleaning looks like in Parsons Green
Food Standards Agency records list about 62 schools, colleges and universities, about 82 care, childcare and hospital premises and about 46 hotels, B&Bs and guest houses registered as food businesses in Parsons Green and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Parsons Green’s nearest hospital, Western Hospital, is about 0.8 miles north. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Getting kit to a London plant room typically means lifts, stairs and an agreed loading slot.
If you manage a school such as Lady Margaret School, ventilation cleaning is best booked for the holidays. If you run an office near Imperial Wharf station, its supply ductwork can gather dust for years before anyone looks inside.

Managing agents and facilities teams in Parsons Green
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Different parts, different methods
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
Common questions in Parsons Green
Can parking be tricky for a job in Parsons Green?
A loading bay, a visitor permit or off-street space near the site in Parsons Green makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
Can the work in Parsons Green be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. It means the site in Parsons Green keeps running as normal. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Do you look at the system first?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, call 0345 646 2711 or drop us a line and tell us about the site and its opening hours.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we are fully insured.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes half a day to a full day per unit, with large plant planned over several shifts. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Parsons Green.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Tell us about site rules, permits or sign-in
- Have your last certificate or report to hand
- Arrange a key holder or contact on site
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
