How we handle AHU cleaning in Horns Green
Our AHU cleaning covers sites in Horns Green and the rest of Kent, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers filter sections, drain trays and heating and cooling coils, and common reasons people get in touch are plant that has been serviced but not cleaned and drain trays holding standing water.
For a building in or near Horns Green, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Horns Green questions
Is Horns Green in your area for AHU cleaning?
Yes, we work in Horns Green and the places around it. Just call us on 0345 646 2711 or use the quote form with a few details of the site.
Can the work in Horns Green be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Horns Green needn’t be disturbed. Your opening times are the first thing we ask for.
Is a quote from photos possible?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. If photos are not enough, we’ll survey first.
Are you insured?

What accreditations do you have?
We are 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.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What about areas you can’t get to?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
Common problems we fix in Horns Green
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Signs it’s time to call us include:
- Coils clogged with dust and debris
- Debris and leaves in the fresh air intake
- Plant that has been serviced but not cleaned
- Air handling units due a clean after building work
Healthcare buildings such as Orpington Hospital, about 3.8 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near Horns Green, yours matters too.

It takes half a day to a full day per unit, with large plant planned over several shifts, and we clear up before we go. The timing of a visit to Horns Green is set by you, and the travel is our side of the planning.

How to get a quote

Related advice
What the work involves, part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.

What affects the quote in Horns Green
We quote each job individually. This is what makes a difference:
- Whether we need access equipment or extra panels
- How big the system is
- Site requirements such as sign-in and permits
- Working hours and out-of-hours timing
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call 0345 646 2711, or send details by email for straight advice and a fixed quote.
What to send for a quote
You don’t need the technical terms. It helps if you can send:
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
- Wide pictures of the system and the area around it
- Any previous report or certificate
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
Multi-site and managed buildings
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. Where responsibility is shared, records matter even more.
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep filter changes on time and recorded
- Flag stale or damp smells in the supply air
- Make sure the unit’s access doors open easily
- Keep the area around the fresh air intake clear
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
