About our AHU cleaning in Offham
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. The work covers dampers and louvres, drain trays and internal panels, and common reasons people get in touch are plant that needs cleaning after a refit and blocked condensate drains and slimy trays.
In a village or hamlet like Offham, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
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.

FAQs for Offham
Is Offham within the area you cover?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Is AHU cleaning available in Offham?
Yes. We work across London and the South East, and Offham is part of that. Just call us on 0345 646 2711, or send details by email with a few details of the site.
Do you have insurance?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
What’s TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
What types of premises do you cover?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
What 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. You get a fixed price before we start.
When to call us in Offham
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
What we are most often called out for:
- Dirty coils holding back the airflow
- Plant that needs cleaning after a refit
- Leaves and litter drawn into the unit
- Units that have only ever had filter changes
If you manage offices or shops near Cooksbridge station, their ventilation can be inspected and cleaned out of hours.

Why it’s worth doing now in Offham
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. In a place like Offham, ductwork and fans are easy to forget until something goes wrong.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.

Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
What a clean won’t put right
Some problems need a different service or another trade:
- Airflow problems caused by the system’s design
- Problems with the unit’s controls or sensors
- Breakdowns that need a mechanical engineer
Not sure which it is? You can ring 0345 646 2711 or send us an email and we will tell you honestly.

Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that won’t bend or flatten the fins.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
