About our AHU cleaning in World's End
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. The work covers drain trays, internal panels and supply and extract fans, and people most often call us about blocked condensate drains and slimy trays and units that have only ever had filter changes.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. In World's End, as elsewhere, cleaning starts with an inspection of what’s there.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What happens if it’s left?
Leave an AHU uncleaned and the dirt does not 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. It’s better booked as a planned job in World's End than handled as an emergency.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

When it’s something else
We’ll always give you a straight diagnosis, so here’s what AHU cleaning won’t do:
- Ductwork downstream of the unit, which is a separate clean
- Leaking heating or cooling coils
- A system that is undersized for the building
If in doubt, call 0345 646 2711 or send us an email and we’ll say what we think.
What the work covers
- Heating and cooling coils
- Drain trays
- Dampers and louvres
- Internal panels
- Supply and extract fans
- Filter sections
How the job changes from site to site
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
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.
World's End questions
Is parking a problem for work in World's End?
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.
Can a school’s ventilation in World's End be done out of term time?
Yes, out-of-term visits are normal for schools. With about 33 schools and colleges on the FSA’s register within roughly a mile and a half of World's End, it pays to plan holiday dates ahead. Just call us on 0345 646 2711, or send details by email with your term dates and we will plan around them.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. We normally quote within one working day, and there’s a 24/7 line for emergencies.
What should I send you?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded for your maintenance team to follow up.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Can you clean without disrupting the building?
Yes. We time the work to fit the building’s hours. Healthcare and care settings are planned with staff.
Is a quote from photos possible?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Make sure condensate is draining away
- Keep filter changes on time and recorded
- Report stiff or damaged access doors
- Note any water around the unit or leaks below it
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
Managing agents and facilities teams in World's End
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
What happens on the day
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, and that takes a single shift for a typical unit, longer for large or heavily soiled ones. Night and weekend working is normal for us in London, and a site in World's End is no exception.
- First we agree when the unit can be switched off, including evenings or weekends.
- 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.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Tell us where we can park and unload
- Clear loose items from the work area
How to get a quote
Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Advice
What affects the quote in World's End
You will get a fixed price before we start. It takes into account:
- How many systems or sites are involved
- When the work can happen, such as evenings, overnight or weekends
- Travel, parking and unloading
- Access, including roofs, risers and ceiling voids
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so there are no surprises.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
- The site address and the type of premises
- Problems your staff have spotted
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.
