How we price AHU cleaning

- Whether we need access equipment or extra panels
- A single visit or a regular plan
- The scale of the work
- Parking and loading at the site
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or drop us a line, and we’ll explain what it covers.
Asking for a quote
We can often survey from photos. The most useful are:
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles
- A few general shots of the system
- Your opening hours and when the area is out of use
If you need AHU cleaning in Dedham, give us a ring on 0345 646 2711, or email photos. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. We normally send a fixed quote within one working day.
AHU cleaning in Dedham, done properly
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. If you are dealing with units that have only ever had filter changes and filters that are clogged or overdue, we can put it right, from drain trays, dampers and louvres and filter sections onwards.
In a village or hamlet like Dedham, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
A written report with photos 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.

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 from a few hours for a compact unit to a day or more for a large one. Seeing the system in photos first means the trip to Dedham can be planned properly.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Tell us where we can park and unload
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Advice
How the job changes from site to site
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with photos so repairs can be planned.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Questions from Dedham
Do you cover smaller places like Dedham?
Yes, Dedham is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Can ventilation in schools around Dedham be cleaned out of term?
Yes, holiday work suits schools best. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Dedham, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
Do you need to switch the unit off?
Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
What happens if you cannot reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
How long will the unit be out of action?
As a guide, it takes one overnight shift for many single units, with bigger plant phased. The shutdown is planned to fit, including evenings or weekends.
Will we get paperwork for the AHU clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
AHU cleaning in Dedham: local notes
There are about 3 schools, colleges and universities on the FSA’s food hygiene register within 1.5 miles or so of the middle of Dedham. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Dedham’s nearest hospital, Severalls Hospital, is about 4.9 miles south-west.

Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
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.
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Make sure condensate is draining away
- Store the TR19 paperwork where auditors can find it
- Report water on the plant room floor
- Report stiff or damaged access doors
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.

Why act early in Dedham
Stuffy rooms and stale smells in a building in Dedham can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. If the system at a site near Dedham fails, there may be nowhere nearby to move to.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
