- Leaking heating or cooling coils
- Breakdowns that need a mechanical engineer
- Ventilation that was badly designed in the first place
If in doubt, call us on 0345 646 2711 or send us an email and we’ll say what we think before booking.

AHU cleaning for kitchens and businesses in Steyning
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you have filters that are clogged or overdue and stale or musty smells from the ventilation, we can help, from drain trays, internal panels and supply and extract fans onwards.
In a place like Steyning, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What affects the cost of AHU cleaning
We quote each job individually. This is what makes a difference:
- The condition we find in the survey
- Working hours and out-of-hours timing
- How many systems or sites are involved
- Parking and loading at the site
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before we start.
Helping us quote
To speed up the quote, send us:
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
- The site address and the type of premises
- Your last certificate, test record or report
Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Managing agents and facilities teams in Steyning
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
The process
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes anything from half a day for one small unit to several shifts for a plant room full of them. Tell us about any gates, ladders or locked plant areas at your site near Steyning when you book.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Have your last certificate or report to hand
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive

Aftercare tips
A little care between visits keeps the system in better shape. We recommend:
- Flag stale or damp smells in the supply air
- Make sure condensate is draining away
- Make sure the unit’s access doors open easily
- Report water on the plant room floor
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
Steyning: your questions answered
Do you clean school ventilation in Steyning in the holidays?
Yes, holiday work suits schools best. Around Steyning, the Food Standards Agency lists about 6 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.
Can you get to a site in Steyning?
Yes, we work in villages as well as towns, and Steyning is covered. The journey is planned ahead, so a few details about the route help.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply phone us on 0345 646 2711, or email photos.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, ring 0345 646 2711 or email us and tell us about the site and its opening hours.
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
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.
AHU cleaning in Steyning: local notes
Food Standards Agency data includes about 6 schools, colleges and universities within about 1.5 miles of central Steyning. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. At about 44 miles from central London, Steyning 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 Steyning, the closest hospital is Southlands Hospital, roughly 4.4 miles south-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Healthcare buildings such as Southlands Hospital, about 4.4 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Steyning, yours matters too. If you manage a school such as Steyning CofE Primary School, ventilation cleaning is best booked for the holidays.
