Alscot: your questions answered
Do you work at weekends in Alscot?
Yes, evening, overnight and weekend work is normal for us. That way a site in Alscot doesn’t have to lose a day’s trading. When you call 0345 646 2711 or drop us a line, mention when the site is quiet.
Can you clean school ventilation in Alscot during the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 5 schools, colleges and universities with registered kitchens within about a mile and a half of Alscot. Just phone us on 0345 646 2711, or email photos with your term dates and we will plan around them.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
What happens to the waste?
We take it away when we go. During the work, it’s contained to keep the area clean.
Do you work in Alscot?
Yes. We work in Alscot and the rest of Buckinghamshire, as part of our work across South East England and London. For a fixed quote, ring 0345 646 2711, or email photos.
Do you have insurance?
Yes. Full insurance covers our work, and we have been trading since 2009.
AHU cleaning in Alscot
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. The work covers dampers and louvres, supply and extract fans and filter sections, and common reasons people get in touch are coils clogged with dust and debris and dirty fans and fan housings.
In a village or hamlet like Alscot, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Change filters on schedule and log each change
- Note any water around the unit or leaks below it
- Store the TR19 paperwork where auditors can find it
- Report stiff or damaged access doors
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Alscot buildings and their air
Food Standards Agency data includes about 5 schools, colleges and universities and about 9 caring premises (care homes, nurseries and hospitals) within roughly a mile and a half of the centre of Alscot. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Stoke Mandeville Hospital is the nearest hospital, about 4.8 miles north of Alscot.

About 36 miles out from central London, Alscot is part of the South East area we work across. The visit is fixed around your opening hours, not ours.
Healthcare buildings such as Stoke Mandeville Hospital, about 4.8 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near Alscot, yours matters too. Classrooms and halls at schools such as Princes Risborough Primary School are easiest to work in when pupils are away. If you manage offices or shops near Monks Risborough station, their ventilation can be inspected and cleaned out of hours.

Different parts, different methods
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
Managing agents and facilities teams in Alscot
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

What AHU cleaning cannot fix
In fairness, some problems need a different fix:
- Controls and BMS settings that run the unit
- Ductwork downstream of the unit, which is a separate clean
- Damaged coils beyond cleaning
If in doubt, give us a ring on 0345 646 2711 or email us and we will say what we think before booking.
