About AHU cleaning in Slough

All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. Typical jobs include leaves and litter drawn into the unit and coils clogged with dust and debris, on dampers and louvres, supply and extract fans and drain trays.

There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes from a few hours for a compact unit to a day or more for a large one.

We agree a shutdown window that suits the building.
Before cleaning, each section is photographed.
We work through the unit from the intake to the outlet.
We finish with the fan section and the drain tray.
After photos are taken and the certificate issued.

What’s near Slough

Around Slough, our work takes us to kitchens and buildings near Herschel Grammar School, St Michael and All Angels and Westgate School and the streets around them. Nearby too are Herschel Park (1.1 miles south-east), The Godolphin Junior Academy (0.6 miles north) and The Moon and Spoon pub (0.6 miles south-east).

Green spaces nearby include Taplow Lake and Burnham Beeches.

Ventilation across Slough

In Slough, we clean ventilation in places such as Cippenham, Chalvey and Britwell and the smaller places around them. We cover every place we list for Slough, 31 in all, with work planned out of hours where buildings stay in use.

Slough is within the area we cover, which takes in London and the South East. Every job is surveyed first and quoted at a fixed price, wherever it is in Slough.

Slough: If you manage a school such as Herschel Grammar School, ventilation cleaning is best booked for the holidays. If you run a surgery, dental practice or care home near Slough, clean ventilation matters as much to you as to a hospital like Upton Hospital (about 0.9 miles south-east).

Part by part

Rooftop and plant room units

Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.

Fans and fan sections

The fan section is cleaned with the unit switched off and isolated with your site team.

Common problems we fix in Slough

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

These are the problems we see most often:

Condensate trays that will not empty
Plant that needs cleaning after a refit
Dirty filters cutting the airflow
Dust built up on fan impellers

Staff cleaning versus specialist work

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.

A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.

How we price AHU cleaning

Your quote is based on your site. We consider:

How many systems or sites are involved
Any permits to work or inductions
The condition we find in the survey
Travel, parking and unloading

What you pay depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.

What we need to know

Before you ask for a quote, gather:

Anything you’ve noticed, such as smells, noise, drips or poor airflow
A few general shots of the system
Your last certificate, test record or report
How we’d reach plant on a roof or in a plant room

To help us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711, or send details by email.

Between visits

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

Keep the certificate and photo report with the plant records
Change filters on schedule and log each change
Check the drain tray is emptying during routine visits
Report musty smells from the vents right away

The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.

Keep the area around the intake clear. What’s near the intake ends up in the unit.

Common questions in Slough

How often do AHUs need cleaning?

There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and the report recommends a next date.

Where does the waste go?

Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.

What’s TR19?

TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

Do you do ventilation duct cleaning too?

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

Can you price the work without visiting?

Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.

How much does AHU cleaning cost in Slough?

Every site is different, so each gets its own fixed quote. For a quote, ring 0345 646 2711 or email us and tell us about the site and its opening hours.

Do you have a 24/7 line?

Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
