AHU cleaning in Hammersmith, done properly
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. If you’re dealing with dust built up on fan impellers and debris and leaves in the fresh air intake, we can help, from heating and cooling coils, filter sections and supply and extract fans onwards.
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 Hammersmith.
A written report with pictures follows each visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

FAQs for Hammersmith
Can you work in Hammersmith outside opening hours?
Yes, nights and weekends are routine for us. It means the site in Hammersmith keeps running as normal. Let us know the hours you’re closed and we will book within them.
How do you handle parking and loading in Hammersmith?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
Do you offer emergency callouts?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
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 any previous paperwork make it quicker. After that, simply give us a ring on 0345 646 2711, or email photos.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. For a quote, phone us on 0345 646 2711, or send details by email and tell us about the site and its opening hours.
AHU cleaning in Hammersmith: local notes
Food Standards Agency records list about 83 schools, colleges and universities, about 91 care, childcare and hospital premises and about 64 hotels and guest houses registered as food businesses within 1.5 miles or so of the middle of Hammersmith. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. West London Hospital is the nearest hospital, about less than half a mile south-east of Hammersmith. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot.
School buildings such as Corona Theatre School are typically done in the holidays, so classrooms aren’t disturbed. For workplaces around Kensington Olympia station with mechanical ventilation, cleaning can be done in the evening or at weekends.
Hammersmith is about 1 mile west of Kensington, in Greater London. Sites in Hammersmith get the same service as everywhere we cover: diagnosis first, a fixed price, out-of-hours working where needed and a written report with photos. Hammersmith is one of 764 places in Greater London we cover for commercial clients. We also work in London, about 6 miles from Hammersmith.
We work across W6, W14, W12 and W4 for AHU cleaning and the roads nearby. If you need AHU cleaning at premises on The Square, Ravenscourt Square and Westcroft Square or anywhere close by, our technicians can take on the work. Neighbouring places we cover for AHU cleaning include Brackenbury Village (1 mile north-west), Brook Green (1 mile east), North End (1 mile east), West Kensington (1 mile east) and Old Chiswick (1 mile south-west). We also work in nearby towns such as London (6 miles east), City of Westminster (4 miles east), Marylebone (4 miles north-east), St Pancras (5 miles north-east), Shoreditch (7 miles east) and Walthamstow (11 miles north-east).
What’s near Hammersmith
Locally, jobs take us to businesses close to The Duke of Hammersmith pub, Brook Green and Polish Library POSK in London and the streets around them. The nearest railway station is Kensington Olympia station, about 0.8 miles east. Other landmarks nearby include West London Hospital (less than half a mile south-east) and Kurdish Museum Library and Archive (under half a mile south-west). Not far away are Campden Hill and WWT London Wetland Centre.
Staff cleaning versus specialist work
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
What we are called out for in Hammersmith
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.
Look out for any of the following:
- Blocked condensate drains and slimy trays
- Intake sections clogged with outdoor debris
- Units that have only ever had filter changes
- Stale or musty smells from the ventilation
Healthcare ventilation, from large hospitals like West London Hospital (about less than half a mile south-east) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before you book
- If the quote is a fixed price or an estimate
- Whether VAT is included
- When they can work, and whether that is outside your opening hours
- Whether the whole system is included, or only the parts that are easy to reach
What a clean won’t put right
We will always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Dirty ducts beyond the unit itself
- Airflow problems caused by the system’s design
- Controls and BMS settings that run the unit
Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we will tell you honestly.
What the work covers
- Heating and cooling coils
- Drain trays
- Filter sections
- Dampers and louvres
- Supply and extract fans
- Internal panels
How the visit 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 from a few hours for a compact unit to a day or more for a large one. For a job in Hammersmith, tell us about loading bays, permits, lifts and roof access when you book.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Tell us the best time to work, such as after service or at a weekend
- Let us know how we reach the system, including roofs, risers and plant rooms

Landlords, agents and facilities managers
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Diary the inspection date recommended in the report
- Stick to the filter change plan
- Note any water around the unit or leaks below it
- Report stiff or damaged access doors
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Leave it or put it right?
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
What you pay depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
