Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
How we handle AHU cleaning in Finstock
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and send you a fixed quote before any cleaning starts. The work covers filter sections, supply and extract fans and internal panels, and common reasons people get in touch are condensate trays that won’t empty and filters that are clogged or overdue.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Think of the report as the 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 and sits alongside the report.

What staff can safely do
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Finstock: your questions answered
Is AHU cleaning available in Finstock?
Yes. Our area runs across London and the South East, Finstock included. You can ring 0345 646 2711 or send us an email and tell us what needs doing.
Will you come out to Finstock?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, with new panels fitted where necessary.
Do you repair air handling units?
We clean the unit and flag faults rather than repair them, with photos where it helps.
What happens if you can’t reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
How do you protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
How it works
Every visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, tidy up and leave you the report. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. In a small place like Finstock, the journey is planned ahead and the visit arranged around the site’s hours.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Clear loose items from the work area
- Have your last certificate or report to hand
- Let us know about permits to work or site inductions

Do you need AHU cleaning in Finstock?
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Common reasons sites call us include:
- Units that have only ever had filter changes
- Dust built up on fan impellers
- Leaves and litter drawn into the unit
- Dust-coated heating and cooling coils
Workplaces around Finstock station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

Aftercare tips
How long the results last depends on use and care. We suggest:
- Note any water around the unit or leaks below it
- Flag stale or damp smells in the supply air
- Diary the inspection date recommended in the report
- Store the TR19 paperwork where auditors can find it
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
