What affects the cost of AHU cleaning
The survey tells us what the work involves. We look at:
- The size of the system
- How many systems or sites are involved
- Where the site is and how we reach it
- One-off work versus a regular cycle
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.
Helping us quote
Before you ask for a quote, gather:
- The paperwork from the last visit, if you have it
- The postcode and the type of business
- The times we could work without disrupting the site
- A few general shots of the system
To get a fixed quote, ring 0345 646 2711 or email us 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 normally come back within one working day.
For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too across Surrey. Larger estates can be phased building by building around the people who use them.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Why it’s worth doing now in Bowlhead Green
If people in a building in Bowlhead Green complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. A fault that closes a site in a village like Bowlhead Green affects everyone who depends on it.

Bowlhead Green: your questions answered
Do you work in villages like Bowlhead Green?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Can you work in Bowlhead Green outside opening hours?
Yes, nights and weekends are routine for us. It means the site in Bowlhead Green keeps running as normal. Just phone us on 0345 646 2711 or drop us a line with your opening times and we will plan around them.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
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. Emergencies are different, because our line is open 24/7.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Can one contract cover all our sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What we’re called out for in Bowlhead Green
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
These are the problems we see most often:
- Air handling units with blocked filters
- Condensate trays that will not empty
- Stale or musty smells from the ventilation
- Air handling units due a clean after building work
Hospitals such as Haslemere and District Hospital (about 3.2 miles south) show how much a building can rely on clean ventilation, and smaller healthcare sites near Bowlhead Green are no different.
What to look for in a quote
- Whether the work can be done while the site is closed
- If they look at the system before pricing
- Whether the figure could change on the day
- When the next visit should be, and why
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Watch for drips or damp patches near the plant
- Check the drain tray is emptying during routine visits
- Store the TR19 paperwork where auditors can find it
- Stick to the filter change plan
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.

Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
