About our AHU cleaning in Paddington
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. If you have odours coming through the supply air and dirty fans and fan housings, we can help.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Paddington, dust settles in the units and ducts year after year.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What happens on the day
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and the area is cleaned down before we leave. Most London sites can’t stop for the day, so work in Paddington is normally done overnight, early in the morning or at weekends.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Find the previous report, if there is one
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend

Leave it or put it right?
If people in a building in Paddington complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Every month a London system goes without attention adds to what has to be done later.
Whatever the type of site, the quote works 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 explain each part.

Questions from Paddington
How do you handle parking and loading in Paddington?
Tell us where a van can stop near your site in Paddington, and about any building rules on loading. Much of our London work is done overnight, which helps.
Do you clean school ventilation in Paddington in the holidays?
Yes. The holidays are the usual time for school work. With about 76 schools and colleges on the FSA’s register within roughly a mile and a half of Paddington, it pays to plan holiday dates ahead. Just ring 0345 646 2711 or use the quote form with your term dates and we will plan around them.
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.
What happens if you cannot reach some of it?
Anything we cannot reach goes on the report, with pictures where possible, and we tell you what would make it reachable, for example new access panels.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Each site gets its own report and photos.
Do you look at the system first?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Is a quote from photos possible?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Do you cover Paddington?
Yes. We cover Paddington and the rest of Greater London, as part of our work across South East England and London. For a fixed quote, call 0345 646 2711 or use the quote form.
Managing agents and facilities teams in Paddington
Facilities teams in offices, schools and healthcare sites book us too in Paddington and across Greater London. Work can be phased by floor, building or site to keep disruption down.
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.
Common problems we fix in Paddington
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Common reasons sites call us include:
- Rooms that smell stuffy when the system runs
- Filters that are clogged or overdue
- Dust built up on fan impellers
- Intake sections clogged with outdoor debris
Healthcare buildings such as Maida Vale Hospital for Nervous Diseases, about 0.7 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Paddington, yours matters too.
What your quote should include
- How areas they can’t reach will be recorded
- Whether they recommend a next date
- Proof of accreditation you can verify
- If the quote is a fixed price or an estimate
Part by part
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with photos so repairs can be planned.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
What AHU cleaning looks like in Paddington
There are about 76 schools, colleges and universities, about 22 care, childcare and hospital premises and about 180 hotels, B&Bs and guest houses on the FSA’s food hygiene register across Paddington and its immediate surroundings (about a mile and a half). Where buildings like these have air handling units, filters, coils and drain trays need regular attention. London plant rooms are often on roofs or in basements reached through occupied floors. Paddington’s nearest hospital, Maida Vale Hospital for Nervous Diseases, is about 0.7 miles north-west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Wherever a school like International Community School has ducted ventilation, a half-term visit keeps the work out of lesson time. Workplaces around London Paddington station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Plan the next inspection before the last report gets filed away
- Report stiff or damaged access doors
- Note any water around the unit or leaks below it
- Flag stale or damp smells in the supply air
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
Staff cleaning versus specialist work
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
