AHU cleaning in Peaslake, done properly
Where a building in Peaslake has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. We’re often asked to deal with odours coming through the supply air and units needing a clean before a new tenant or handover, across heating and cooling coils, supply and extract fans and drain trays.
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.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

How the visit works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Seeing the system in photos first means the trip to Peaslake can be planned properly.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
How to prepare
- Mention any sign-in, permit or induction we need
- Make sure someone can let us in and lock up afterwards
- Clear loose items from the work area

What AHU cleaning can’t fix
A few issues sit outside what this work can do:
- Problems with the unit’s controls or sensors
- Leaking heating or cooling coils
- A system that’s undersized for the building
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we will tell you honestly.
Where we work
- Drain trays
- Internal panels
- Filter sections
- Heating and cooling coils
- Dampers and louvres
- Supply and extract fans
Why deal with it now?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Somewhere as small as Peaslake, losing a kitchen or building to a fault is felt by everyone who uses it.
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711, or send details by email, and we will explain what it covers.

- Every visit written up, with photos
- Fully insured

AHU cleaning around Peaslake
Going by the FSA’s register, there are about 3 schools, colleges and universities serving food across Peaslake and its immediate surroundings (about a mile and a half). Busy, occupied buildings like these are where clean supply air matters most. About 26 miles out from central London, Peaslake 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. For Peaslake, the closest hospital is St. Luke’s Hospital, roughly 5.8 miles north-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
For buildings in and around Peaslake, TR19® Air cleaning starts with an inspection.

Aftercare tips
Once we have finished, these simple steps help:
- Check the drain tray is emptying during routine visits
- Plan the next inspection before the last report gets filed away
- Keep inspection doors on the unit in good order
- Flag stale or damp smells in the supply air
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Managing agents and facilities teams in Peaslake
We also work for facilities teams across offices, schools and healthcare across Surrey. Work can be phased by floor, building or site around the people who use them.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.

What we are called out for in Peaslake
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
The symptoms we’re asked about most include:
- Air handling units with blocked filters
- Dust built up on fan impellers
- Air handling units never cleaned inside
- Drain trays holding standing water
Hospitals such as St. Luke’s Hospital (about 5.8 miles north-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Peaslake are no different.
