AHU cleaning in Brompton, done properly
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. The work covers dampers and louvres, internal panels and drain trays, and the jobs we see most are plant that needs cleaning after a refit and plant that has been serviced but not cleaned.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. In Brompton, as elsewhere, cleaning starts with an inspection of what’s there.
Think of the report as the system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

AHU cleaning around Brompton
The FSA’s food hygiene register lists about 67 schools, colleges and universities, about 24 caring premises (care homes, nurseries and hospitals) and about 172 hotels and B&Bs with registered kitchens or food service in and around Brompton, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. In London, ventilation plant is often on the roof or below ground, so the work is usually done out of hours. The nearest hospital to Brompton is Royal Marsden Hospital, about less than half a mile south-west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Healthcare buildings such as Royal Marsden Hospital, about within half a mile south-west, depend on their ventilation; if you manage a surgery, clinic or care home near Brompton, yours matters too. If you manage shops or offices close to London Victoria station, a TR19® Air inspection shows whether the ductwork needs cleaning. For schools like Hellenic College of London, the holidays are the usual time to inspect and clean ventilation.

In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Leave it or put it right?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. A busy site in Brompton builds up dirt and wear quickly, so putting it off makes the eventual job larger.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across Greater London. Work can be phased by floor, building or site around the people who use them.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Part by part
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
Internal casing and panels
We open each section through its doors and close them securely when we are done, and check every one is shut.
What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Brompton.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Before we arrive
- Name a contact who can let us in at the agreed time
- Mention any locked doors, roof access or ceiling voids
- Find the previous report, if there is one

Common questions in Brompton
Can a school’s ventilation in Brompton be done out of term time?
Yes, holiday work suits schools best. Around Brompton, the Food Standards Agency lists about 67 schools and colleges with registered kitchens within a mile and a half or so. You can phone us on 0345 646 2711, or send details by email with the dates the site is empty.
Can parking be tricky for a job in Brompton?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. If the building has a loading slot system, we’ll book into it.
How much does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, normally ready within one working day.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
What do you clean inside the unit?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
Do you look at the system first?
Yes. We always survey first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
Will the ventilation be off while you clean?
Yes. We can’t clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and we will quote them together.

How we price AHU cleaning
The quote reflects the site in front of us. We consider:
- A single visit or a regular plan
- Working hours and out-of-hours timing
- Parking and loading at the site
- Whether several sites go on one quote
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
- A few general shots of the system
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
What a clean will not put right
We’d rather tell you now than book work that won’t help, so here are the limits:
- Coils that are corroded or leaking and need replacing
- Faulty motors, drives or bearings
- Airflow problems caused by the system’s design
Not sure which it is? You can give us a ring on 0345 646 2711 or email us and we’ll tell you honestly.
