About our AHU cleaning in Bisley
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’re dealing with intake sections clogged with outdoor debris and air handling units with blocked filters, we can help.
For a building near Bisley, the visit is planned around how it’s used, and the journey is planned ahead. The method does not change: inspect first, clean, then record what was done.
Good records are part of the job. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Questions from Bisley
Do you cover smaller places like Bisley?
Yes. Villages and rural sites across the South East are part of our work, Bisley included. The journey is planned ahead, so a few details about the route help.
Can you work in Bisley outside opening hours?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Bisley needn’t be disturbed. Tell us your opening hours when you ask for a quote.
How long does an AHU clean take?
Cleaning takes from a few hours for a compact unit to a day or more for a large one. Bigger units can be phased, so ring 0345 646 2711 or send us an email to talk it through.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
Can you price the work without visiting?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and we usually come back within one working day. Some sites still need a visit, and we will say so.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Why it’s worth doing now in Bisley
Standing water in a drain tray does not clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. It’s better to plan the work at a site near Bisley than wait for a failure.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we will price it together.

Part by part
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
What happens on the day
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 from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. Visits to a place like Bisley are planned ahead, so we arrive with what the survey says the job needs.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Dig out any earlier paperwork for the system
- Tell us where we can park and unload
- Let us know how we reach the system, including roofs, risers and plant rooms
Get a fixed quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Related advice
What affects the cost of AHU cleaning
The diagnosis comes before the price. The main factors are:
- A single visit or a regular plan
- The size of the system
- How many systems or sites are involved
- Site requirements such as sign-in and permits
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before work begins.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Where the site is and what kind of site it is
- Wide photos of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
For a fixed quote, call 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.

Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. We cover Bisley, about 26 miles from central London, as part of our work across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site.
