How we handle AHU cleaning in Waterloo

All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. The work covers filter sections, heating and cooling coils and supply and extract fans, and people most often call us about debris and leaves in the fresh air intake and filters that are clogged or overdue.

London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Waterloo, dust settles in the units and ducts year after year.

Good records are part of the job. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

In-house cleaning or a specialist?

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

How the visit works

Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. In Waterloo, as across London, we normally work overnight or at weekends and hand the site back ready to open.

  1. We look at the unit and the plant area during the survey.
  2. We sheet the area and the unit is isolated.
  3. Dirt and debris are removed from each section.
  4. Coils and trays are cleaned and the condensate drain cleared.
  5. The unit is closed up and handed back, with a report to follow.

Before we arrive

  • Let us know about permits to work or site inductions
  • Mention any parking or loading restrictions
  • Make sure someone can let us in and lock up afterwards

Ventilation in Waterloo buildings

The FSA’s food hygiene register lists about 84 schools, colleges and universities, about 41 caring premises (care homes, nurseries and hospitals) and about 142 hotels, B&Bs and guest houses with registered kitchens or food service within about 1.5 miles of central Waterloo. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Waterloo’s nearest hospital, General Lying-In Hospital, is about within half a mile west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Ventilation cleaning in London buildings is normally planned for evenings or weekends.

Hospitals such as General Lying-In Hospital (about less than half a mile west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Waterloo are no different. For workplaces around London Waterloo station with mechanical ventilation, cleaning can be done in the evening or at weekends. Wherever a school like Oasis Academy Johanna has ducted ventilation, a half-term visit keeps the work out of lesson time.

Your questions about AHU cleaning in Waterloo

Can you work in Waterloo outside opening hours?

Yes, evening, overnight and weekend work is normal for us. It means the site in Waterloo keeps running as normal. Just call us on 0345 646 2711 or drop us a line with your opening times and we will plan around them.

Does London parking affect a job in Waterloo?

A loading bay, a visitor permit or off-street space near the site in Waterloo makes the visit easier to plan. If the building has a loading slot system, we’ll book into it.

What should I send you?

Where the site is, what it is and when it’s open, along with a few photos and any previous report.

What’s included in an AHU clean?

All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.

Are you fully insured?

Yes. Full insurance covers our work, and we have been trading since 2009.

Can you set up regular visits?

Yes, of course. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.

How long will the unit be out of action?

Cleaning takes half a day to a full day per unit, with large plant planned over several shifts. Large plant can be split over several shifts, and you can phone us on 0345 646 2711, or email photos to plan it.

What’s TR19?

It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.

For landlords and multi-site operators

Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.

Honest limits

We won’t sell you work that doesn’t address the problem, so these are the things it will not cover:

  • Coils that are corroded or leaking and need replacing
  • Faulty motors, drives or bearings
  • Problems with the unit’s controls or sensors

If you’re not sure, just call us on 0345 646 2711 or drop us a line and we will give you a straight answer before you book.

Where we work

  • Drain trays
  • Dampers and louvres
  • Filter sections
  • Supply and extract fans
  • Heating and cooling coils
  • Internal panels

Part by part

Fans and fan sections

Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.

Rooftop and plant room units

Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey so the quote reflects it.

Between visits

No system stays clean for ever, but care slows the build-up. Our tips:

  • Check the drain tray is emptying during routine visits
  • Plan the next inspection before the last report gets filed away
  • Keep the area around the fresh air intake clear
  • Keep the certificate and photo report with the plant records

The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.

Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
