Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, 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.
AHU cleaning in Hassocks
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. Common call-outs are for dust-coated heating and cooling coils and dirty fans and fan housings, on supply and extract fans, heating and cooling coils and internal panels.
Around a place like Hassocks, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Your questions about AHU cleaning in Hassocks
Will you come out to Hassocks?
Yes. Villages and rural sites across the South East are part of our work, Hassocks included. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Hassocks for AHU cleaning?
Yes, we work in Hassocks and the places around it. A fixed quote usually follows within one working day of the survey details.
Do you need to switch the unit off?
Yes, for the time we are working on it. Out-of-hours work is available to keep disruption down.
How long will the unit be out of action?
It takes anything from half a day for one small unit to several shifts for a plant room full of them. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
When should our AHU next be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
Are you insured?
Yes. We are fully insured, and the details are available on request.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
The process
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Everything the job in Hassocks needs is worked out beforehand, from the survey.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Let us know when the site is closed or quiet
- Mention any sign-in, permit or induction we need
