AHU cleaning for kitchens and businesses in West Horsley
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. If you have condensate trays that won’t empty and debris and leaves in the fresh air intake, we can help, from filter sections, heating and cooling coils and internal panels onwards.
In a place like West Horsley, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

School buildings such as The Raleigh School are normally done in the holidays, so classrooms aren’t disturbed.

What staff can safely do
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’ll take a look and give you a fixed quote.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
Why act early in West Horsley
Standing water in a drain tray does not clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. A quieter site near West Horsley still needs its system looked after.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.

What happens on the day
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. Getting to the system matters more than parking in a place like West Horsley, so let us know how to reach it.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Mention any sign-in, permit or induction we need
- Tell us where we can park and unload
Ask for a quote
To get a fixed quote, call us on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We normally come back within one working day.

Fixed quotes for AHU cleaning in West Horsley
There’s no set price list, because sites vary so much. What we look at:
- When the work can happen, such as evenings, overnight or weekends
- Site requirements such as sign-in and permits
- The condition we find in the survey
- Whether we need access equipment or extra panels
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
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:
- Any access panels or hatches you can see
- The times we could work without disrupting the site
- Any previous report or certificate
- Where the plant sits or the system leaves the building, such as a roof or outside wall
We don’t publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, call us on 0345 646 2711 or email us.
When to call us in West Horsley
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in West Horsley, that is air they breathe for hours at a time.
Look out for these warning signs:
- Rooms that smell stuffy when the system runs
- Leaves and litter drawn into the unit
- Plant that needs cleaning after a refit
- Dust built up on fan impellers
If you manage offices or shops near Horsley station, their ventilation can be inspected and cleaned out of hours.

FAQs for West Horsley
Can a school’s ventilation in West Horsley be done out of term time?
Yes, and it’s the easiest time to do it. Around West Horsley, the Food Standards Agency lists about 4 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Do you cover smaller places like West Horsley?
Yes, smaller places are covered as well as towns. A survey first, from photos or a visit, means we arrive with the right kit.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
How much does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, normally ready within one working day.
Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Do you repair air handling units?
We clean the unit and flag faults rather than repair them, with photos where it helps.
What AHU cleaning cannot fix
Some problems need a different service or another trade:
- Dirty ducts beyond the unit itself
- Ventilation that was badly designed in the first place
- Building management system faults
Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we will tell you honestly.
