How we handle AHU cleaning in Blewbury
Our AHU cleans for sites in Blewbury cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. The work covers internal panels, supply and extract fans and drain trays, and the jobs we see most are plant that needs cleaning after a refit and dirty coils holding back the airflow.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What the work involves, part by part
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
What AHU cleaning looks like in Blewbury
At about 49 miles from central London, Blewbury sits well inside the area we cover. The visit is fixed around your opening hours, not ours.
Classrooms and halls at schools such as Blewbury Endowed Church of England Primary School are easiest to work in when pupils are away.
Blewbury is about 3 miles south of Didcot, in Oxfordshire. Across the OX11 area, we can carry out AHU cleaning at your premises. We cover 443 places across Oxfordshire, from busy centres to quieter spots. Oxford is in our area too, around 12 miles away.
Work in OX11 follows the same survey, fixed quote and written report as everywhere else we cover. We cover sites on Church Road, London Road and Church End and the roads around them. Close by, we work in Woodway (1 mile south), Upton (1 mile north-west), Aston Tirrold (1 mile east), East Hagbourne (2 miles north) and West Hagbourne (2 miles north-west). Larger places within reach include Oxford (12 miles north), Didcot (3 miles north), Abingdon-on-Thames (8 miles north), Wantage (8 miles west), Henley-on-Thames (14 miles east) and Grove (9 miles west).
Local landmarks in Blewbury

Nearby you will also find Brightwell Castle (4.1 miles north-east) and Atlas Computer Laboratory (3.5 miles west). For a walk, there’s Mowbray Fields and Churn Hill.
What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

What affects the quote in Blewbury
We quote each job individually. These are the things that affect it:
- The scale of the work
- Access, including roofs, risers and ceiling voids
- Site requirements such as sign-in and permits
- Parking and loading at the site
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- A few general shots of the system
- Detail shots of panels, filters and grilles
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The times we could work without disrupting the site
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
Keeping the system healthy
After the visit, a few habits help the work last:
- Make sure the unit’s access doors open easily
- Keep the area around the fresh air intake clear
- Stick to the filter change plan
- Note any water around the unit or leaks below it
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
The process
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes one overnight shift for many single units, with bigger plant phased. Somewhere like Blewbury, lanes, gates and parking are worth mentioning in advance.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Move anything stored near the system
- Have your last certificate or report to hand
- Make sure equipment near the work can be switched off and left to cool

What we’re called out for in Blewbury
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
These are the problems we see most often:
- Fan sections that haven’t been cleaned in years
- Filters that are clogged or overdue
- Condensate trays that won’t empty
- Intake sections clogged with outdoor debris
An inspection comes first for any ventilation job around Blewbury, so the cleaning matches what’s there.
