AHU cleaning in Thorpe Cross, done properly
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. Typical jobs include air handling units with blocked filters and units that have only ever had filter changes, on drain trays, filter sections and heating and cooling coils.
Work in a small place like Thorpe Cross starts with agreeing access and timings.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Staff cleaning versus specialist work
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
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 will take a look and give you a fixed quote.
The process
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes half a day to a full day per unit, with large plant planned over several shifts, and the area is cleaned down before we leave. The timing of a visit to Thorpe Cross is set by you, and the travel is our side of the planning.
- First the unit is surveyed, from pictures 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.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.
Preparing for the visit
- Move anything stored near the system
- Arrange a key holder or contact on site
- Mention any locked doors, roof access or ceiling voids

Advice
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Look at the condensate drain whenever the unit is serviced
- Plan the next inspection before the last report gets filed away
- Report stiff or damaged access doors
- Report water on the plant room floor
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Part by part
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.

What affects the quote in Thorpe Cross
The survey tells us what the work involves. We look at:
- A single visit or a regular plan
- Travel, parking and unloading
- How big the system is
- Whether we need access equipment or extra panels
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, call us on 0345 646 2711 or send us an email for straight advice and a fixed quote.
Helping us quote
You do not need the technical terms. Just send:
- The postcode and the type of business
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
Managing agents and facilities teams in Thorpe Cross
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
Thorpe Cross: your questions answered
Do you work overnight in Thorpe Cross?
Yes, nights and weekends are routine for us. The work in Thorpe Cross can fit around your hours. Let us know the hours you are closed and we’ll book within them.
Do you cover smaller places like Thorpe Cross?
Yes. Thorpe Cross is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Do you repair air handling units?
The clean includes noting faults, but repairs sit with your maintenance contractor, with pictures where it helps.
What if parts of the system cannot be reached?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
Will we get paperwork for the AHU clean?
Yes, both a certificate and a report with pictures. The report also suggests when the unit should next be inspected.
Can you price the work without visiting?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
