How we price AHU cleaning
The survey tells us what the work involves. We look at:
- How big the system is
- Access, including roofs, risers and ceiling voids
- How many systems or sites are involved
- Site rules, permits and inductions
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
What to send for a quote
There’s no need for technical detail. Just send:
- The site address and the type of premises
- Any previous report or certificate
- Wide photos of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.
How we handle AHU cleaning in Rough Common
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. Common call-outs are for plant that needs cleaning after a refit and dirty filters cutting the airflow, on filter sections, internal panels and drain trays.
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.
A written report with pictures follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What we do, step by step
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes from a few hours for a compact unit to a day or more for a large one. If you can send pictures, we can arrive in Rough Common knowing what to expect.
- 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.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system
- Mention any locked doors, roof access or ceiling voids
Getting a quote
Getting a quote doesn’t take long. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Staff cleaning versus specialist work
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. The inside of ducts and units needs a specialist.
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.

Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. At about 51 miles from central London, Rough Common sits well inside the area we cover. Evening, overnight and weekend visits are all possible. Rough Common’s nearest hospital, Eastbridge Hospital of St Thomas the Martyr, is about 1.6 miles south-east.

Between visits
Aftercare is simple, and it helps at the next visit:
- Plan the next inspection before the last report gets filed away
- Report musty smells from the vents straight away
- Report water on the plant room floor
- Store the TR19 paperwork where auditors can find it
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
Why deal with it now?
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Equipment tucked in a roof space or outbuilding near Rough Common rarely gets looked at unless someone books it.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before we start.

Common problems we fix in Rough Common
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
These are the problems we see most often:
- Rooms that smell stuffy when the system runs
- Air handling units with blocked filters
- Debris and leaves in the fresh air intake
- Units needing a clean before a new tenant or handover
Healthcare buildings such as Eastbridge Hospital of St Thomas the Martyr, about 1.6 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Rough Common, yours matters too.

Part by part
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Your questions about AHU cleaning in Rough Common
Is Rough Common within the area you cover?
Yes, Rough Common is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
Do you clean school ventilation in Rough Common in the holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 16 schools, colleges and universities with registered kitchens within about a mile and a half of Rough Common. Booking early in the term gives the best choice of holiday dates.
Do you survey before quoting?
Yes. We always survey first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
How much does AHU cleaning cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
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.
Can you clean without disrupting the building?
Yes, wherever it helps the building. We plan the shutdown window with you.
