About our AHU cleaning in Hook Common
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. If you’re dealing with units needing a clean before a new tenant or handover and drain trays holding standing water, we can help, from internal panels, heating and cooling coils and filter sections onwards.
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.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

FAQs for Hook Common
Is Hook Common within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Hook Common included. The journey is planned ahead, so a few details about the route help.
Can you clean school ventilation in Hook Common during the holidays?
Yes, holiday work suits schools best. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Hook Common. Tell us your holiday dates and we will book the visit for when the site is empty.
How often do AHUs need cleaning?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
What happens to the waste?
We take it away when we go. While we work, it’s kept contained so the area stays clean.
How it works
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Rural roads and tight entrances are worth telling us about before a visit to Hook Common.
- 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.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure someone can let us in and lock up afterwards

Aftercare tips
Here’s the after-treatment advice, short and simple:
- Keep the certificate and photo report with the plant records
- Don’t store bins or materials near the intake
- Keep filter changes on time and recorded
- Make sure condensate is draining away
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.

Why it’s worth doing now in Hook Common
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Planning a trip to Hook Common ahead is easier for everyone than a rushed one.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Staff cleaning and specialist work aren’t the same thing. 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.
What affects the cost of AHU cleaning
We quote each job individually. This is what makes a difference:
- Whether several sites go on one quote
- Working hours and out-of-hours timing
- Site requirements such as sign-in and permits
- A single visit or a regular plan
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before any work starts.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
- The paperwork from the last visit, if you have it
- A few general shots of the system
For a fixed quote, call 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You’ll typically have a quote within one working day.
