How the job changes from site to site

Drain trays

Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.

Fans and fan sections

The fan section is cleaned with the unit switched off and isolated in agreement with the site.

AHU cleaning in Chafford Hundred

No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and give you a fixed quote, so you know where you stand. We are often asked to deal with fan sections that haven’t been cleaned in years and debris and leaves in the fresh air intake, across heating and cooling coils, dampers and louvres and drain trays.

Smaller buildings around Chafford Hundred often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.

Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What a clean will not put right

Some problems need a different service or another trade:

  • Leaking heating or cooling coils
  • Ventilation that was badly designed in the first place
  • The supply and extract ducts, quoted separately

Not sure which it is? You can ring 0345 646 2711 or drop us a line and we’ll tell you honestly before you book.

What the work covers

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

Signs you need AHU cleaning in Chafford Hundred

Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.

What we’re most often called out for:

  • Dust-coated heating and cooling coils
  • Condensate trays that won’t empty
  • Rooms that smell stuffy when the system runs
  • Air handling units never cleaned inside

Healthcare buildings such as Thurrock Community Hospital, about 1.2 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Chafford Hundred, yours matters too.

What your quote should include

  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • Whether the figure could change on the day
  • Whether the whole system is included, or only the parts that are easy to reach
  • Whether the work can be done while the site is closed

Questions to ask before you book

Why act early in Chafford Hundred

Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, ready to show anyone who asks. Around Chafford Hundred, a kitchen or building out of action is missed right away.

The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before any work starts.

Between visits

Simple habits between visits make a real difference. We recommend:

  • Keep the certificate and photo report with the plant records
  • Check the drain tray is emptying during routine visits
  • Do not ignore odours coming through the grilles
  • Note any water around the unit or leaks below it

We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.

Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.

The process

Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Getting to the system matters more than parking in a place like Chafford Hundred, so let us know how to reach it.

  1. We agree a shutdown window that suits the building.
  2. Before cleaning, each section is photographed.
  3. Filters, coils and internal surfaces are cleaned from intake to discharge.
  4. The fan and drain tray are cleaned and the drain checked.
  5. We take after pictures and issue the certificate and report.

Getting ready for the visit

  • Make sure someone can let us in and lock up afterwards
  • Tell us the best time to work, such as after service or at a weekend
  • Mention any locked doors, roof access or ceiling voids

Your questions about AHU cleaning in Chafford Hundred

Can a school’s ventilation in Chafford Hundred be done out of term time?

Yes. The holidays are the usual time for school work. Food Standards Agency records list about 17 schools, colleges and universities with registered kitchens within about a mile and a half of Chafford Hundred. Just call us on 0345 646 2711, or send details by email with your term dates and we will plan around them.

Do you cover smaller places like Chafford Hundred?

Yes. Villages and rural sites across the South East are part of our work, Chafford Hundred included. Just mention lanes, gates or anything else about the site when you book.

Can you look after several sites?

Yes. One number covers all your sites in our area, with visits on a regular schedule.

How long does it take to clean an air handling unit?

Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.

How far ahead should we book?

It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.

What do you do with what you remove?

It leaves the site with us when we go. During the work, it’s contained to keep the area clean.

Do you repair air handling units?

Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We’ll flag anything we notice during the clean.

What about areas you can’t get to?

We record them on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.

For landlords and multi-site operators

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.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
