What affects the cost of AHU cleaning
You will get a fixed price before any work starts. It’s based on:
- How big the system is
- How easy every part is to reach
- Any permits to work or inductions
- Where the site is and how we reach it
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before we start.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Problems your staff have spotted
- The postcode and the type of business
- A few general shots of the system
- Where the plant sits or the system leaves the building, such as a roof or outside wall
To get a fixed quote, call 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You will normally have a quote within one working day.
AHU cleaning in Holloway Down, done properly
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. If you have units needing a clean before a new tenant or handover and dirty fans and fan housings, 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. An inspection first shows where cleaning is needed in a building in Holloway Down.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

AHU cleaning in Holloway Down: local notes
Food Standards Agency data includes about 43 schools, colleges and universities, about 84 care, childcare and hospital premises and about 15 hotels and B&Bs in Holloway Down and the streets around it, up to about 1.5 miles out. Busy, occupied buildings like these are where clean supply air matters most. Getting kit to a London plant room typically means lifts, stairs and an agreed loading slot. About 0.9 miles south of Holloway Down is Queen Mary's Hospital for the East End, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Classrooms and halls at schools such as The Jenny Hammond Primary School are easiest to work in when pupils are away. If you run an office near Maryland station, its supply ductwork can gather dust for years before anyone looks inside.
Holloway Down is about 1 mile north of Stratford, in Greater London. From the centre of Holloway Down to the outskirts, AHU cleaning is available to all kinds of commercial premises, from a single unit to a large public building. 764 places in Greater London are on our list, large and small. Our London page covers sites nearby (6 miles or so).

What we are called out for in Holloway Down
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
Keep an eye out for any of the following:
- Drain trays holding standing water
- Intake sections clogged with outdoor debris
- Units needing a clean before a new tenant or handover
- Coils clogged with dust and debris
If you run a surgery, dental practice or care home near Holloway Down, clean ventilation matters as much to you as to a hospital like Queen Mary's Hospital for the East End (about 0.9 miles south).

FAQs for Holloway Down
Do you work overnight in Holloway Down?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
How do you handle parking and loading in Holloway Down?
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.
When should our AHU next be cleaned?
That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
Do you look at the system first?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
What’s TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Each site gets its own report and pictures.
Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Report water on the plant room floor
- Check the drain tray is emptying during routine visits
- Do not store bins or materials near the intake
- Change filters on schedule and log each change
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
Managing agents and facilities teams in Holloway Down
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
What we do, step by step
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Holloway Down.
- 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.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Tell us about site rules, permits or sign-in
- Let us know about parking and loading

Advice
Why act early in Holloway Down
Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. In Holloway Down, as across London, ductwork often passes through shared risers and other people’s space.
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so you know where you stand.
