AHU cleaning for sites in Cowesfield Gate

What staff can safely do

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.

AHU cleaning in Cowesfield Gate, done properly

Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. If you are dealing with rooms that smell stuffy when the system runs and dirty filters cutting the airflow, we can help, from supply and extract fans, dampers and louvres and internal panels onwards.

For a building in or near Cowesfield Gate, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.

The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What affects the cost of AHU cleaning

Sites vary more than people expect. What affects the quote:

  • How many systems or sites are involved
  • How big the system is
  • Where the site is and how we reach it
  • The condition we find in the survey

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.

What we need to know

Photos and a few facts are often enough to price the work. Send what you can of the following:

  • When the site is open and when it’s quiet
  • Where the site is and what kind of site it is
  • Wide pictures of the system and the area around it
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Cowesfield Gate questions

Is AHU cleaning available in Cowesfield Gate?

Yes. We work across London and the South East, and Cowesfield Gate is part of that. You can ring 0345 646 2711, or email photos and let us know what needs doing.

Can you come to Cowesfield Gate after we close?

Yes, evening, overnight and weekend work is normal for us. It means the site in Cowesfield Gate keeps running as normal. Let us know the hours you’re closed and we’ll book within them.

Will we get paperwork for the AHU clean?

Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.

Which accreditations do you hold?

Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.

Will the ventilation be off while you clean?

Yes. We can’t clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.

What is TR19?

It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.

How much does AHU cleaning cost?

There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before work begins.

How much notice do you need?

Earlier is better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.

Honest limits

An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:

  • Ductwork downstream of the unit, which is a separate clean
  • Mechanical faults with motors, belts or bearings
  • Coils that are corroded or leaking and need replacing

If you’re not sure, just give us a ring on 0345 646 2711, or email photos and we will give you a straight answer.

What we work on in Cowesfield Gate

  • Internal panels
  • Dampers and louvres
  • Heating and cooling coils

Landlords, agents and facilities managers

For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.

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.

Common problems we fix in Cowesfield Gate

Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.

Look out for any of the following:

  • Air handling units due a clean after building work
  • Dirty fans and fan housings
  • Intake sections clogged with outdoor debris
  • Drain trays holding standing water

Hospitals such as Romsey Community Hospital (about 5.7 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Cowesfield Gate are no different.

Questions to ask before booking

  • When the next visit should be, and why
  • How VAT is shown on the quote
  • Whether the work can be done while the site is closed
  • Exactly which parts of the system are covered

How to choose an extract cleaning contractor

How the visit works

We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes from a few hours for a compact unit to a day or more for a large one. Photos of the system and how to reach it help us plan a visit to Cowesfield Gate.

  1. We look at the unit and the plant area during the survey.
  2. The area is protected and the unit made safe.
  3. Dirt and debris are removed from each section.
  4. We clean the coils and clear the tray and drain.
  5. The unit is closed up and handed back, with a report to follow.

Getting ready for the visit

  • Tell us where we can park and unload
  • Allow time for equipment near the work to be turned off and cool down
  • Have your last certificate or report to hand

Ask for a quote

There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, ring 0345 646 2711 or send us an email.

Leave it or put it right?

A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. Equipment tucked in a roof space or outbuilding near Cowesfield Gate rarely gets looked at unless someone books it.

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 make a difference.
