AHU Cleaning in Heckfield
Our technicians work in Heckfield on cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Out-of-hours visits, a fixed quote and a written report with photos on every job.
- Coils clogged with dust and debris

- Plant that has been serviced but not cleaned
For landlords and multi-site operators
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.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
About our AHU cleaning in Heckfield
Our AHU cleaning covers sites in Heckfield and the rest of Hampshire, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. Common call-outs are for dirty fans and fan housings and filters that are clogged or overdue, across supply and extract fans, heating and cooling coils and internal panels.
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.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Signs you need AHU cleaning in Heckfield
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
What we’re most often called out for:
- Plant that has been serviced but not cleaned
- Air handling units with blocked filters
- Blocked condensate drains and slimy trays
- Units needing a clean before a new tenant or handover
An inspection comes first for any ventilation job around Heckfield, so the cleaning matches what’s there.
What your quote should include
- Proof of accreditation you can verify
- What’s included in the scope, part by part
- What happens if part of the system can’t be accessed
- Whether the price is fixed
How the job changes from site to site
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
How it works
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes half a day to a full day per unit, with large plant planned over several shifts, and we clear up before we go. Photos of the system and how to reach it help us plan a visit to Heckfield.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Find the previous report, if there is one
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
For a fixed quote, phone us on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You will usually have a quote within one working day.
Related advice
Looking after it afterwards
To keep the system working properly between visits:
- Report musty smells from the vents straight away
- Do not store bins or materials near the intake
- Keep the certificate and photo report with the plant records
- Report water on the plant room floor
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
What affects the cost of AHU cleaning
Every site gets its own quote. This is what makes a difference:
- One-off work versus a regular cycle
- Any permits to work or inductions
- Where the site is and how we reach it
- Access, including roofs, risers and ceiling voids
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
- Where the site is and what kind of site it is
- Any previous report or certificate

Heckfield questions
Is Heckfield in your area for AHU cleaning?
Yes, we work in Heckfield and the places around it. You can call us on 0345 646 2711, or email photos and let us know what needs doing.
Will you come out to Heckfield?
Yes. Villages and rural sites across the South East are part of our work, Heckfield included. A survey first, from photos or a visit, means we arrive with the right kit.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Are you fully insured?
Yes. We carry full insurance and have been trading since 2009.
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.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
What happens to the waste?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.

Why act early in Heckfield
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. In a small place like Heckfield, a system that fails can take a site out of use.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.
Why us?
- Ventilation hygiene specialists since 2009
- Every visit written up, with pictures
- Fixed quotes from a survey or pictures
- Out-of-hours work and a 24/7 emergency line
