AHU cleaning in Mott's Mill
Our AHU cleans for sites in Mott's Mill cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. If you’re dealing with leaves and litter drawn into the unit and air handling units never cleaned inside, we can put it right.
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.
Good records are part of the job. You get a written report with pictures after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What the work involves, part by part
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Common questions in Mott's Mill
Will you come out to Mott's Mill?
Yes. Villages and rural sites across the South East are part of our work, Mott's Mill included. Just mention lanes, gates or anything else about the site when you book.
Do you offer AHU cleaning in Mott's Mill?
Yes, Mott's Mill is within the area we cover across London and the South East. Get in touch with the details and we will arrange a survey.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. We usually quote within one working day, and there’s a 24/7 line for emergencies.
Can you price the work without visiting?
Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
Can you clean the AHU out of hours?
Yes. The clean is planned around when the unit can be switched off. Healthcare and care settings are planned with staff.
Can you clean the ducts connected to the AHU?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
What happens on the day
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before any work starts, and the area around the work is covered and protected. The work itself takes from a few hours for a compact unit to a day or more for a large one. For a village or hamlet like Mott's Mill, tell us about narrow lanes, gates and parking when you book.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Let us know about permits to work or site inductions
- Have your last certificate or report to hand
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Ask for a quote
We do not publish a price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711, or email photos.
Advice
Fixed quotes for AHU cleaning in Mott's Mill
We quote each job individually. This is what makes a difference:
- Where the site is and how we reach it
- The number of sites or systems
- Any permits to work or inductions
- What state the system is in
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.
What we need to know
Many jobs can be priced from photos and some basics. Useful things to send:
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
- Wide photos of the system and the area around it
- Detail shots of panels, filters and grilles

Common problems we fix in Mott's Mill
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
Any of these means the system needs a check-up:
- Units needing a clean before a new tenant or handover
- Filters that are clogged or overdue
- Drain trays holding standing water
- Coils clogged with dust and debris
For schools like Groombridge St Thomas' Church of England Primary School, the holidays are the usual time to inspect and clean ventilation.
What to look for in a quote
- Which accreditations they hold, and whether you can check them
- What paperwork you get at the end
- Whether the quote is based on a survey or photos
- If the quote is a fixed price or an estimate
Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Why act early in Mott's Mill
Stuffy rooms and stale smells in a building in Mott's Mill can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. Systems in rural buildings are often out of sight and out of mind.
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.

Managing agents and facilities teams in Mott's Mill
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. With shared responsibility, good records help everyone.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
