AHU cleaning in Small Dole, done properly
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote, so you know where you stand. Typical jobs include plant that needs cleaning after a refit and dust-coated heating and cooling coils, across drain trays, supply and extract fans and internal panels.
Somewhere as small as Small Dole, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Leave it or put it right?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. With notice, the visit to Small Dole can be fitted around your bookings and events.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

Different parts, different methods
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with photos so you can decide on any repairs.
Signs you need AHU cleaning in Small Dole
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
Look out for any of the following:
- Dust built up on fan impellers
- Debris and leaves in the fresh air intake
- Drain trays holding standing water
- Units needing a clean before a new tenant or handover
In Small Dole, we look inside the system before deciding what needs cleaning.
What to look for in a quote

Ventilation in Small Dole buildings
We cover Small Dole, about 42 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours. Small Dole’s nearest hospital, Southlands Hospital, is about 4.4 miles south. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Healthcare buildings such as Southlands Hospital, about 4.4 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Small Dole, yours matters too.
Small Dole is about 5 miles north of Shoreham-by-Sea, in West Sussex. Small Dole gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with pictures. Small Dole is one of 371 towns, villages and districts in West Sussex we cover for commercial clients. Brighton is in our area too, about 8 miles from Small Dole.
Work in BN5 follows the same survey, fixed quote and written report as everywhere else we cover. We cover sites on Downsview, Tottington Drive and Orchard Close and nearby roads. We also cover the places around Small Dole: Woodmancote (2 miles north-east), Henfield (2 miles north), Blackstone (2 miles north-east), Albourne (3 miles north-east) and High Cross (3 miles north-east).

A little further out are Southlands Hospital (4.4 miles south) and Steyning Museum (2.6 miles south-west). The countryside around Small Dole includes Woods Mill and Truleigh Hill.
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
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.

Other services in Small Dole
For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
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.
How it works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes one overnight shift for many single units, with bigger plant phased. The timing of a visit to Small Dole is set by you, and the travel is our side of the planning.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Name a contact who can let us in at the agreed time
- Dig out any earlier paperwork for the system
- Let us know how we reach the system, including roofs, risers and plant rooms

FAQs for Small Dole
Do you cover smaller places like Small Dole?
Yes. Villages and rural sites across the South East are part of our work, Small Dole included. Just mention lanes, gates or anything else about the site when you book.
Can you come to Small Dole after we close?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. When you give us a ring on 0345 646 2711 or email us, mention when the site is quiet.
What does AHU cleaning cost?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.
Do you need to switch the unit off?
Yes, for the time we are working on it. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
Do you have insurance?
Yes. We carry full insurance, and we have been trading since 2009.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
