Islington AHU cleaning

How the job changes from site to site
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
AHU cleaning in Islington
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. We are often asked to deal with drain trays holding standing water and plant that has been serviced but not cleaned, across dampers and louvres, heating and cooling coils and drain trays.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. In Islington, as elsewhere, cleaning starts with an inspection of what’s there.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
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, next to our reports.
What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. Before any visit in Islington, we agree where the van can stop and how equipment reaches the system.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Mention any sign-in, permit or induction we need
- Find the previous report, if there is one
- Agree a time when the area can be out of use

Advice
Other services in Islington
What affects the quote in Islington
We do not publish a price list, because no two systems are the same. The quote depends on:
- The scale of the work
- Working hours and out-of-hours timing
- Access, including roofs, risers and ceiling voids
- Any permits to work or inductions
The cost depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.
Asking for a quote
When you call or email, these details help:
- Any access panels or hatches you can see
- The postcode and the type of business
- Photos showing the whole system and its surroundings
- The paperwork from the last visit, if you have it
Getting a quote does not take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Aftercare tips
Once we have finished, these simple steps help:
- Flag stale or damp smells in the supply air
- Keep inspection doors on the unit in good order
- Report water on the plant room floor
- Diary the inspection date recommended in the report
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Islington questions
Do you clean school ventilation in Islington in the holidays?
Yes, holiday work suits schools best. With about 70 schools and colleges on the FSA’s register within roughly a mile and a half of Islington, it pays to plan holiday dates ahead. Send us your term dates when you call us on 0345 646 2711 or send us an email, and we’ll fit the work in.
Can you come to Islington after we close?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Islington needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What’s TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
How much notice do you need?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we’ll usually reply within one working day.
Can you fix a faulty AHU?
We clean the unit and flag faults rather than repair them, with photos where it helps.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
When something else is needed
A few issues sit outside what this work can do:
- Faulty motors, drives or bearings
- Leaking heating or cooling coils
- Controls and BMS settings that run the unit
If you’re not sure, just call 0345 646 2711, or send details by email and we will give you a straight answer before booking.

Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Islington buildings and their air
Going by the FSA’s register, there are about 70 schools, colleges and universities, about 85 hospitals, care homes and childcare premises and about 100 hotels and B&Bs serving food across Islington and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Islington’s nearest hospital, King's College Hospital Charity, is about 0.7 miles north-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. In London, ventilation plant is often on the roof or below ground, so the work is usually done out of hours.
Classrooms and halls at schools such as Islington Proprietary School are easiest to work in when pupils are away. For workplaces around Essex Road station with mechanical ventilation, cleaning can be done in the evening or at weekends. Healthcare ventilation, from large hospitals like King's College Hospital Charity (about 0.7 miles north-west) to small clinics, depends on clean filters, coils and ducts.
