What affects the cost of AHU cleaning
The diagnosis comes before the price. The main factors are:
- Any permits to work or inductions
- How easy every part is to reach
- A single visit or a regular plan
- The scale of the work
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so you know where you stand.

How we handle AHU cleaning in Furzedown
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. If you are dealing with rooms that smell stuffy when the system runs and debris and leaves in the fresh air intake, we can put it right.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Furzedown is typically planned out of hours. Loading and parking are planned with the building first.
We have been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Why deal with it now?
If people in a building in Furzedown complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. A building in Furzedown may have flats or offices above and alongside, and a fault in the system can affect them too.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before we start.

Your questions about AHU cleaning in Furzedown
Can you clean school ventilation in Furzedown during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 33 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Furzedown. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can the work in Furzedown be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Furzedown needn’t be disturbed. Your opening times are the first thing we ask for.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we’re fully insured.
Will we get paperwork for the AHU clean?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
What’s included in an AHU clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
How long does an AHU clean take?
As a guide, it takes a single shift for a typical unit, longer for large or heavily soiled ones. We plan the shutdown around that, out of hours if needed.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
How do you protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Managing agents and facilities teams in Furzedown
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
What happens on the day
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. Most London sites can’t stop for the day, so work in Furzedown is normally done overnight, early in the morning or at weekends.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- 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 when the site is closed or quiet

Furzedown buildings and their air
Food Standards Agency data includes about 33 schools, colleges and universities, about 85 hospitals, care homes and childcare premises and about 7 hotels and guest houses within roughly a mile and a half of the centre of Furzedown. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Ventilation cleaning in London buildings is usually planned for evenings or weekends. The nearest hospital to Furzedown is St Benedict's Hospital, about within half a mile west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Wherever a school like Graveney School has ducted ventilation, a half-term visit keeps the work out of lesson time. Healthcare ventilation, from large hospitals like St Benedict's Hospital (about less than half a mile west) to small clinics, depends on clean filters, coils and ducts.

Staff cleaning versus specialist work
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. Reaching it takes a specialist with the right equipment.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Aftercare tips
A little care between visits keeps the system in better shape. We recommend:
- Make sure the unit’s access doors open easily
- Do not ignore odours coming through the grilles
- Watch for drips or damp patches near the plant
- Clear leaves and litter away from the intake
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
