About our AHU cleaning in Singleton
Our AHU cleans for sites in Singleton cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers dampers and louvres, supply and extract fans and heating and cooling coils, and the jobs we see most are dirty fans and fan housings and condensate trays that won’t empty.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Singleton buildings and their air
Going by the FSA’s register, there are about 7 schools, colleges and universities serving food across Singleton and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Singleton’s nearest hospital, Chichester Centre, is about 4.5 miles south. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. We cover Singleton, about 50 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included.
Wherever a school like Singleton CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Singleton is about 5 miles north of Chichester, in West Sussex. Across the PO18 area, we cover AHU cleaning for commercial sites. Singleton is one of 371 towns, villages and districts in West Sussex we cover for AHU cleaning. There’s also a page for Portsmouth, about 16 miles away.
We work across the PO18 postcode area for AHU cleaning and the streets around it. If you need AHU cleaning at premises on Downley Close, The Leys and Charlton Road or anywhere close by, our technicians can take on the work. Neighbouring places we cover for AHU cleaning include Charlton (1 mile east), West Dean (1 mile west), East Dean (2 miles east), Cocking (3 miles north) and Heyshott (3 miles north-east). We also work in nearby towns such as Bognor Regis (9 miles south), Chichester (5 miles south), Selsey (12 miles south), Littlehampton (12 miles south-east), Emsworth (9 miles south-west) and Rustington (13 miles south-east).
Near you in Singleton
We work in commercial kitchens and buildings around The Partridge Inn. A little further out are Weald and Downland Gridshell (under half a mile south-west) and Chichester Centre (4.5 miles south). Open spaces near Singleton include Levin Down and Kingley Vale National Nature Reserve.
For landlords and multi-site operators
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Between visits
Simple habits between visits make a real difference. We recommend:
- Keep inspection doors on the unit in good order
- Book the next check in line with the report
- Check the drain tray is emptying during routine visits
- Report musty smells from the vents straight away
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Day-to-day cleaning is something your team can do: 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, which is where we come in.
What the work involves, part by part
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
How it works
Our technicians bring everything the work needs, 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 one overnight shift for many single units, with bigger plant phased. Photos of the system and how to reach it help us plan a visit to Singleton.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Mention any parking or loading restrictions
- Dig out any earlier paperwork for the system

Questions from Singleton
Do you work at weekends in Singleton?
Yes. We work evenings, overnight and at weekends. The work in Singleton can fit around your hours. Let us know the hours you are closed and we will book within them.
Can you get to a site in Singleton?
Yes. Villages and rural sites across the South East are part of our work, Singleton included. The journey is planned ahead, so a few details about the route help.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Will we get paperwork for the AHU clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
Signs you need AHU cleaning in Singleton
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Most sites get in touch when they notice one of these:
- Dust-coated heating and cooling coils
- Air handling units never cleaned inside
- Drain trays holding standing water
- Debris and leaves in the fresh air intake
Healthcare buildings such as Chichester Centre, about 4.5 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Singleton, yours matters too.
Questions to ask before booking
