AHU cleaning in Sunbury-on-Thames, done properly
Where a building in Sunbury-on-Thames has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. The work covers drain trays, internal panels and supply and extract fans, and people most often call us about leaves and litter drawn into the unit and fan sections that haven’t been cleaned in years.
Buildings in towns like Sunbury-on-Thames often have ventilation added in stages, with units on the roof or in a plant room. The work starts with an inspection to decide what needs cleaning, so you’re not paying for more than the system needs.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.

FAQs for Sunbury-on-Thames
Can the work in Sunbury-on-Thames be done at night or at weekends?
Yes, nights and weekends are routine for us. It means the site in Sunbury-on-Thames keeps running as normal. When you call 0345 646 2711, or email photos, mention when the site is quiet.
Is Sunbury-on-Thames in your area for AHU cleaning?
Yes, we work in Sunbury-on-Thames and the places around it. A fixed quote typically follows within one working day of the survey details.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What’s included in an AHU clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
Managing agents and facilities teams in Sunbury-on-Thames
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Report musty smells from the vents straight away
- Keep the certificate and photo report with the plant records
- Don’t store bins or materials near the intake
- Diary the inspection date recommended in the report
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Fixed quotes for AHU cleaning in Sunbury-on-Thames
There’s no set price list, because no two systems are the same. What we look at:
- The condition of the system
- How big the system is
- A single visit or a regular plan
- Any permits to work or inductions
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, phone us on 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
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.
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. Before the visit, a few photos of the system and how to reach it help us plan the work in Sunbury-on-Thames.
- 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.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Find the previous report, if there is one
- Mention any locked doors, roof access or ceiling voids
- Allow time for equipment near the work to be turned off and cool down

- Debris and leaves in the fresh air intake
- Filters that are clogged or overdue
- Condensate trays that won’t empty
If you run a surgery, dental practice or care home near Sunbury-on-Thames, clean ventilation matters as much to you as to a hospital like No. 2 New Zealand General Hospital (about 2 miles south).

Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
