AHU cleaning in Wentworth, 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 the report shows exactly what was done. If you have units needing a clean before a new tenant or handover and blocked condensate drains and slimy trays, we can help.
Work in a small place like Wentworth starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Think of the report as the 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, ready for your insurer.

Do you need AHU cleaning in Wentworth?
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
What we are most often called out for:
- Debris and leaves in the fresh air intake
- Plant that needs cleaning after a refit
- Fan sections that haven’t been cleaned in years
- Coils clogged with dust and debris
St. Peter's Hospital, about 3.3 miles south-east, is the nearest hospital to Wentworth, and healthcare sites of every size need their supply air kept clean.
What your quote should include
- What paperwork you get at the end
- Whether the whole system is included, or only the parts that are easy to reach
- Whether they recommend a next date
- Which accreditations they hold, and whether you can check them
Aftercare tips
A little care between visits keeps the system in better shape. We recommend:
- Keep the certificate and photo report with the plant records
- Plan the next inspection before the last report gets filed away
- Do not ignore odours coming through the grilles
- Check the drain tray is emptying during routine visits
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
How we price AHU cleaning
Sites vary more than people expect. The main factors:
- Parking and loading at the site
- Site rules, permits and inductions
- Whether several sites go on one quote
- The times the site is available
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, call us on 0345 646 2711, or send details by email for straight advice and a fixed quote.
What we need to know
The more you tell us, the more accurate the quote. With your enquiry, please include:
- The roof, plant room or outside wall the system runs to
- Photos showing the whole system and its surroundings
- Where the site is and what kind of site it is
- The times we could work without disrupting the site
To get a fixed quote, give us a ring on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
What we do, step by step
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. A few photos of the system help us make the most of a visit to a place like Wentworth.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Find the previous report, if there is one
- Mention any sign-in, permit or induction we need

Wentworth buildings and their air
Going by the FSA’s register, there are about 3 schools, colleges and universities serving food within about 1.5 miles of central Wentworth. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. We cover Wentworth, about 22 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours. About 3.3 miles south-east of Wentworth is St. Peter's Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
School buildings such as Christ Church CofE Aided Infant School are normally done in the holidays, so classrooms aren’t disturbed.

What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. If the system at a site near Wentworth fails, there may be nowhere nearby to move to.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

Different parts, different methods
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
FAQs for Wentworth
Do you work in villages like Wentworth?
Yes. Villages and rural sites across the South East are part of our work, Wentworth included. The journey is planned ahead, so a few details about the route help.
Can a school’s ventilation in Wentworth be done out of term time?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Wentworth. Just phone us on 0345 646 2711 or email us with your term dates and we’ll plan around them.
How long does it take to clean an air handling unit?
As a guide, it takes a single shift for a typical unit, longer for large or heavily soiled ones. The shutdown is planned to fit, including evenings or weekends.
When should our AHU next be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Will the ventilation be off while you clean?
Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building is not left without ventilation when it’s busy.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
What do you need from me for a quote?
A short description and a few photos, with the address and opening hours. If we need more, we’ll ask.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
