About our AHU cleaning in Dalston
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 filters that are clogged or overdue and blocked condensate drains and slimy trays, we can help.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. In Dalston, as elsewhere, cleaning starts with an inspection of what’s there.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Your questions about AHU cleaning in Dalston
Can the work in Dalston be done at night or at weekends?
Yes, we can come after you close and finish before you open. That way a site in Dalston does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Is parking a problem for work in Dalston?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Night visits tend to make loading easier on London streets.
Do you work in Dalston?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Dalston included.
How long does an AHU clean take?
As a guide, it takes anything from half a day for one small unit to several shifts for a plant room full of them. The shutdown is planned to fit, out of hours if needed.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, and new panels can be fitted.
What should I send you?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply give us a ring on 0345 646 2711, or send details by email.
What happens if you can’t reach some of it?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
What affects the quote in Dalston
The quote reflects the site in front of us. We consider:
- A single visit or a regular plan
- The size of the system
- Parking and loading at the site
- Site rules, permits and inductions
Kitchens, offices, schools and hospitals are all priced 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 go through it with you.
Helping us quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Your last certificate, test record or report
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The roof, plant room or outside wall the system runs to
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Then call us on 0345 646 2711 or email us.
What AHU cleaning looks like in Dalston
Going by the FSA’s register, there are about 46 schools, colleges and universities, about 64 care, childcare and hospital premises and about 16 hotels and B&Bs serving food across Dalston and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About under half a mile north-east of Dalston is German Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Ventilation cleaning in London buildings is usually planned for evenings or weekends.
If you run an office near Dalston Junction station, its supply ductwork can gather dust for years before anyone looks inside. German Hospital, about under half a mile north-east, is the nearest hospital to Dalston, and healthcare sites of every size need their supply air kept clean. If you manage a school such as Holy Trinity Church of England Primary School, ventilation cleaning is best booked for the holidays.
Dalston is about 1 mile north-east of Hoxton, in Greater London. We carry out AHU cleaning for commercial premises of every kind in Dalston and the rest of Greater London. 764 places in Greater London are on our list, large and small.

How it works
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, clear away and leave you the report. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Getting kit into a London building takes planning, so let us know where we can load and park in Dalston.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Let us know about parking and loading
- Clear loose items from the work area
- Dig out any earlier paperwork for the system

Different parts, different methods
Drain trays
Older trays can corrode and start leaking. We record their condition with photos so you can decide on any repairs.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
Why deal with it now?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, particularly where damp has made it stick. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
What you get with us
- Fully insured
- Ventilation hygiene specialists since 2009
- A written report with photos after every visit

Honest limits
Before booking, it helps to know what’s not included:
- Ductwork downstream of the unit, which is a separate clean
- Problems with the unit’s controls or sensors
- Breakdowns that need a mechanical engineer
If in doubt, phone us on 0345 646 2711, or send details by email and we’ll say what we think before you book.

Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
