Your questions about AHU cleaning in Chesham Bois
Can you come to Chesham Bois after we close?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Chesham Bois needn’t be disturbed. Let us know the hours you are closed and we will book within them.
Can you clean school ventilation in Chesham Bois during the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 16 schools and colleges with food registrations within roughly a mile and a half of Chesham Bois. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Is there a report after cleaning?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
Can you look after several sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
Do you repair air handling units?
The clean includes noting faults, but repairs sit with your maintenance contractor, with photos where it helps.
Where does the waste go?
We take it away at the end of the visit. During the work, it’s contained so the area stays clean.
What accreditations do you have?
We hold 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.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
About our AHU cleaning in Chesham Bois
Where a building in Chesham Bois has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. If you are dealing with coils clogged with dust and debris and odours coming through the supply air, we can help.
For a building near Chesham Bois, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Ventilation in Chesham Bois buildings
Going by the FSA’s register, there are about 16 schools, colleges and universities and about 18 caring premises (care homes, nurseries and hospitals) serving food across Chesham Bois and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Chesham Bois is about 25 miles from central London, well within the area we cover across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site. Chesham Bois’s nearest hospital, Amersham Hospital, is about 1.7 miles south-west. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
If you manage offices or shops near Amersham station, their ventilation can be inspected and cleaned out of hours. Amersham Hospital, about 1.7 miles south-west, is the nearest hospital to Chesham Bois, and healthcare sites of every size need their supply air kept clean.
Chesham Bois is about 1 mile north of Amersham, in Buckinghamshire. Chesham Bois gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with photos. Across Buckinghamshire, we cover 263 places, and Chesham Bois is one of them. Reading is in our area too, about 23 miles from Chesham Bois.

We also work in nearby towns such as Aylesbury (13 miles north-west), High Wycombe (7 miles south-west), Marlow (11 miles south-west), Beaconsfield (6 miles south), Chalfont St Peter (6 miles south) and Elmhurst (13 miles north-west).

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
The process
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes from a few hours for a compact unit to a day or more for a large one. Tell us about any gates, ladders or locked plant areas at your site near Chesham Bois when you book.
- 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.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Clear loose items from the work area
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool

Landlords, agents and facilities managers
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Part by part
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
Why deal with it now?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. Light use slows the build-up but doesn’t stop it.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, ring 0345 646 2711 or email us for straight advice and a fixed quote.

Whatever surrounds a building in Chesham Bois, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
What we’re most often called out for:
- Units needing a clean before a new tenant or handover
- Dirty filters cutting the airflow
- Dust built up on fan impellers
- Rooms that smell stuffy when the system runs
If you manage a school such as Elangeni School, ventilation cleaning is best booked for the holidays.
