Why act early in Hookwood
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. It’s simpler to plan the work at Hookwood now than to arrange it in a hurry later.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before we start.
Why book with us
- A written report with photos after every visit
- Out-of-hours work and a 24/7 emergency line
- Full insurance on every job
- One number for every site across the South East and London
AHU cleaning for kitchens and businesses in Hookwood
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers heating and cooling coils, internal panels and filter sections, and the jobs we see most are air handling units due a clean after building work and dirty coils holding back the airflow.
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.
Good records are part of the job. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What affects the cost of AHU cleaning
The price is fixed before any work begins. It’s based on:
- Whether it’s a one-off visit or part of a schedule
- The condition of the system
- Travel, parking and unloading
- Working hours and out-of-hours timing
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- Where the site is and what kind of site it is
- Wide photos of the system and the area around it
- Problems your staff have spotted
- Detail shots of panels, filters and grilles
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Between visits
So the system stays in good health:
- Make sure condensate is draining away
- Report musty smells from the vents straight away
- Keep the area around the fresh air intake clear
- Change filters on schedule and log each change
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Common questions in Hookwood
Is Hookwood within the area you cover?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Do you do school ventilation cleaning in Hookwood in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Hookwood. Just phone us on 0345 646 2711, or email photos with your term dates and we’ll plan around them.
How long does an AHU clean take?
The work takes half a day to a full day per unit, with large plant planned over several shifts. Bigger units can be phased, so ring 0345 646 2711, or send details by email to talk it through.
How much notice should we give?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
Can you price the work without visiting?
Normally, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. Some sites still need a visit, and we’ll say so.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
How do you protect the area?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. At the end, the area is cleaned down.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.
Part by part
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.
How it works
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Visits to a village like Hookwood are booked in advance, at a time that suits whoever runs the site.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about parking and loading

Common problems we fix in Hookwood
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
It’s time to book a visit if you see:
- Coils clogged with dust and debris
- Air handling units never cleaned inside
- Units needing a clean before a new tenant or handover
- Dirty fans and fan housings
For schools like Manorfield Primary and Nursery School, the holidays are the usual time to inspect and clean ventilation.
What to look for in a quote
- What records you’ll receive afterwards
- Proof of accreditation you can verify

What your team can do, and what needs us
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
