How we handle AHU cleaning in Deddington
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. If you have dust built up on fan impellers and filters that are clogged or overdue, we can put it right.
For a building in or near Deddington, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

What affects the cost of AHU cleaning
The diagnosis comes before the price. The main factors are:
- One-off work versus a regular cycle
- Site requirements such as sign-in and permits
- The times the site is available
- Whether several sites go on one quote
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before work begins.
What we need to know
To help us quote quickly, please include:
- Close-ups of filters, grilles, hatches or access panels
- The postcode and the type of business
- The roof, plant room or outside wall the system runs to
- A few general shots of the system
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, give us a ring on 0345 646 2711, or send details by email.
When something else is needed
In fairness, some problems need a different fix:
- Mechanical faults with motors, belts or bearings
- Airflow problems caused by the system’s design
- Building management system faults
If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think.

Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Your questions about AHU cleaning in Deddington
Can you get to a site in Deddington?
Yes. Villages and rural sites across the South East are part of our work, Deddington included. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you clean school ventilation in Deddington in the holidays?
Yes. The holidays are the usual time for school work. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Deddington. You can call us on 0345 646 2711 or use the quote form with the dates the site is empty.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we will quote them together.
Do you work evenings or weekends?
Yes, if daytime working is not practical. We plan the shutdown window with you.
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 do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. At the end, the area is cleaned down.
Aftercare tips
To keep the system working properly between visits:
- Clear leaves and litter away from the intake
- Diary the inspection date recommended in the report
- Report musty smells from the vents right away
- Change filters on schedule and log each change
The report suggests a date for the next inspection or clean, 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. Once filters clog, dirt starts getting past them.
Landlords, agents and facilities managers
Facilities teams in offices, schools and healthcare sites book us too in Deddington and across Oxfordshire. Larger estates can be phased building by building to keep disruption down.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
What we do, step by step
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. The timing of a visit to Deddington is set by you, and the travel is our side of the planning.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear loose items from the work area
How to get a quote
To get a fixed quote, call 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You will normally have a quote within one working day.
