What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
About our AHU cleaning in Westcott
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. The work covers filter sections, supply and extract fans and drain trays, and people most often call us about dust-coated heating and cooling coils and debris and leaves in the fresh air intake.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What affects the quote in Westcott
We quote each job individually. This is what makes a difference:
- Whether several sites go on one quote
- Site rules, permits and inductions
- Where the site is and how we reach it
- How big the system is
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- Wide pictures of the system and the area around it
- Any previous report or certificate
- Any symptoms, from odd noises to smells or leaks
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.
What AHU cleaning can’t fix
Some problems need a different service or another trade:
- Damaged coils beyond cleaning
- Airflow problems caused by the system’s design
- Faulty motors, drives or bearings
Not sure which it is? You can call 0345 646 2711, or send details by email and we’ll tell you honestly before you book.

Ventilation in Westcott buildings
The FSA’s food hygiene register lists about 3 schools, colleges and universities with registered kitchens or food service within roughly a mile and a half of the centre of Westcott. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. At about 44 miles from central London, Westcott sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you. For Westcott, the closest hospital is St John's Hospital, roughly 4.6 miles south-east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Classrooms and halls at schools such as Westcott Church of England School are easiest to work in when pupils are away.

- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
