Witley questions
Can the work in Witley be done at night or at weekends?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Witley needn’t be disturbed. When you call us on 0345 646 2711, or send details by email, mention when the site is quiet.
Do you cover smaller places like Witley?
Yes, we work in villages as well as towns, and Witley is covered. A survey first, from photos or a visit, means we arrive with the right kit.
How long will the unit be out of action?
Typically the clean takes half a day to a full day per unit, with large plant planned over several shifts. The shutdown is planned to fit, including evenings or weekends.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
Where does the waste go?
It leaves the site with us at the end of the visit. While we work, it’s kept contained so the area stays clean.
Do you have insurance?
Yes. Full insurance covers our work and have been trading since 2009.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
How we handle AHU cleaning in Witley
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you have plant that has been serviced but not cleaned and stale or musty smells from the ventilation, we can put it right.
In rural areas, ventilation units are often in roof voids 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.

Other services in Witley
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Witley buildings and their air
Food Standards Agency records list about 3 caring premises (care homes, nurseries and hospitals) registered as food businesses within roughly a mile and a half of the centre of Witley. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Witley’s nearest hospital, Milford Hospital, is about 1.4 miles north-east. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. About 34 miles out from central London, Witley is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you.
If you run a surgery, dental practice or care home near Witley, clean ventilation matters as much to you as to a hospital like Milford Hospital (about 1.4 miles north-east). If you run an office near Milford (Surrey) station, its supply ductwork can gather dust for years before anyone looks inside.

Signs you need AHU cleaning in Witley
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
Common reasons sites call us include:
- Filters that are clogged or overdue
- Leaves and litter drawn into the unit
- Air handling units due a clean after building work
- Plant that has been serviced but not cleaned
For schools like The Chandler CofE Aided Junior School, the holidays are the usual time to inspect and clean ventilation.

Why it’s worth doing now in Witley
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. With notice, the visit to Witley can be fitted around your bookings and events.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
Why us?
- Full insurance on every job
- A written report with photos after each visit
- A fixed price before any work starts
- Survey first, then a fixed quote

Honest limits
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It will not put right:
- Damaged coils beyond cleaning
- Ductwork downstream of the unit, which is a separate clean
- Mechanical faults with motors, belts or bearings
If you’re not sure, just give us a ring on 0345 646 2711 or email us and we will give you a straight answer.

How the visit works

- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.

Getting a quote
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
Related advice
Looking after it afterwards
To keep the system working properly between visits:
- Flag stale or damp smells in the supply air
- Plan the next inspection before the last report gets filed away
- Look at the condensate drain whenever the unit is serviced
- Report water on the plant room floor
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
