How we handle AHU cleaning in Naphill
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote before any cleaning starts. The work covers internal panels, supply and extract fans and drain trays, and people most often call us about coils clogged with dust and debris and air handling units due a clean after building work.
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.
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, with full insurance on top.

Why deal with it now?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. In a small place like Naphill, a system that fails can take a site out of use.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.

Naphill questions
Do you work at weekends in Naphill?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Naphill needn’t be disturbed. Just phone us on 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Do you work in villages like Naphill?
Yes. Naphill is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, phone us on 0345 646 2711, or email photos and tell us about the site and its opening hours.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Can you fix a faulty AHU?
The clean includes noting faults, but repairs sit with your maintenance contractor, with photos where it helps.
What AHU cleaning cannot fix
It’s worth knowing the limits before booking:
- Coils that are corroded or leaking and need replacing
- A system that’s undersized for the building
- Problems with the unit’s controls or sensors
Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we will tell you honestly before you book.
What the work covers
- Supply and extract fans
- Drain trays
- Heating and cooling coils
- Filter sections
- Dampers and louvres
- Internal panels
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. For a village or hamlet like Naphill, tell us about narrow lanes, gates and parking when you book.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Move anything stored near the system
- Agree a time when the area can be out of use
Getting a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, give us a ring on 0345 646 2711, or email photos.

Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Look at the condensate drain whenever the unit is serviced
- Don’t ignore odours coming through the grilles
- Keep the certificate and photo report with the plant records
- Clear leaves and litter away from the intake
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
Fixed quotes for AHU cleaning in Naphill
Sites vary more than people expect. The main factors:
- The size of the system
- Working hours and out-of-hours timing
- What state the system is in
- Where the site is and how we reach it
We do not list prices on the website, because each job is priced on what it involves. For a fixed quote, call us on 0345 646 2711 or drop us a line, and we’ll explain what it covers.
What to send for a quote
To speed up the quote, send us:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The site address and the type of premises
- Your opening hours and when the area is out of use
- Problems your staff have spotted
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

About 3 miles south of Naphill is Wycombe Hospital, the nearest hospital.

For schools like Naphill and Walters Ash School, the holidays are the usual time to inspect and clean ventilation. Healthcare buildings such as Wycombe Hospital, about 3 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Naphill, yours matters too.

Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
We also work for facilities teams across offices, schools and healthcare across Buckinghamshire. Larger estates can be phased building by building around the people who use them.
