What we do, step by step

On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes one overnight shift for many single units, with bigger plant phased. Security desks and permits-to-work are routine in London, so let us know what your building in Broadwater Farm needs from us.

  1. First the unit is surveyed, from pictures or a visit, and the scope agreed.
  2. With your site team, the unit is switched off and isolated, then the area around it protected.
  3. We clean or change the filters as agreed, then clean the coils, fan and internal panels.
  4. Drain trays are cleared and cleaned and the outlet checked.
  5. You get a TR19® certificate and a photo report.

Getting ready for the visit

  • Make sure someone can let us in and lock up afterwards
  • Tell us about site rules, permits or sign-in
  • Let us know when the site is closed or quiet

How to get a quote

Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

AHU cleaning in Broadwater Farm

Where a building in Broadwater Farm has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. If you are dealing with dirty fans and fan housings and intake sections clogged with outdoor debris, we can help, from filter sections, heating and cooling coils and drain trays onwards.

London buildings tend to keep their plant on the roof or below ground, so work in Broadwater Farm is often done in the evening or at weekends. Loading and parking are planned with the building first.

Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

How we price AHU cleaning

We quote each job individually. These are the things that affect it:

  • Whether we need access equipment or extra panels
  • How many systems or sites are involved
  • Working hours and out-of-hours timing
  • The scale of the work

The cost depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.

Helping us quote

We can often survey from pictures. The most useful are:

  • Photos showing the whole system and its surroundings
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Any access panels or hatches you can see
  • Where the site is and what kind of site it is

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Staff cleaning versus specialist work

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.

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.

AHU cleaning around Broadwater Farm

Going by the FSA’s register, there are about 45 schools, colleges and universities and about 42 caring premises (care homes, nurseries and hospitals) serving food within about 1.5 miles of central Broadwater Farm. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 1.3 miles north of Broadwater Farm is North Middlesex University Hospital, the nearest hospital. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.

Hospitals such as North Middlesex University Hospital (about 1.3 miles north) show how much a building can rely on clean ventilation, and smaller healthcare sites near Broadwater Farm are no different. If you run an office near Bruce Grove station, its supply ductwork can gather dust for years before anyone looks inside.

Between visits

Looking after the system between visits is straightforward, and it helps at the next visit:

  • Make sure condensate is draining away
  • Keep the area around the fresh air intake clear
  • Make sure the unit’s access doors open easily
  • Do not ignore odours coming through the grilles

Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.

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

Honest limits

We won’t sell you work that doesn’t address the problem, so here are the limits:

  • Ventilation that was badly designed in the first place
  • Ductwork downstream of the unit, which is a separate clean
  • Breakdowns that need a mechanical engineer

If in doubt, ring 0345 646 2711, or email photos and we’ll say what we think.

Where we work

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

When to call us in Broadwater Farm

An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.

What we’re most often called out for:

  • Fan sections that haven’t been cleaned in years
  • Rooms that smell stuffy when the system runs
  • Condensate trays that won’t empty
  • Intake sections clogged with outdoor debris

If you manage a school such as The Willow Primary School, ventilation cleaning is best booked for the holidays.

Questions to ask before you book

Part by part

Drain trays

A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.

Internal casing and panels

Dust settles on every internal surface of the unit. We clean each section from intake to discharge.

FAQs for Broadwater Farm

Can you work in Broadwater Farm outside opening hours?

Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.

Is parking a problem for work in Broadwater Farm?

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

How do you keep the site clean during the work?

We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.

What information do you need?

The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.

Where does the waste go?

We take it away at the end of the visit. During the work, it’s contained so the area stays clean.

Do you cover Broadwater Farm?

Yes. Broadwater Farm is part of the area we cover, within the South East and London area we cover.

Do you clean the ductwork as well?

Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.

Do you look at the system first?

Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
