About our AHU cleaning in Osney
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. Typical jobs include rooms that smell stuffy when the system runs and condensate trays that won’t empty, across supply and extract fans, heating and cooling coils and dampers and louvres.
Smaller buildings around Osney often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What your team can do, and what needs 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.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
AHU cleaning in Osney: local notes
Food Standards Agency records list about 76 schools, colleges and universities, about 17 care, childcare and hospital premises and about 14 hotels and B&Bs registered as food businesses within about 1.5 miles of central Osney. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Radcliffe Infirmary is the nearest hospital, about 0.8 miles north-east of Osney. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. At about 54 miles from central London, Osney sits well inside the area we cover. Evening, overnight and weekend visits are all possible.
Radcliffe Infirmary, about 0.8 miles north-east, is the nearest hospital to Osney, and healthcare sites of every size need their supply air kept clean. Workplaces around Oxford station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. If you manage a school such as West Oxford Community Primary School, ventilation cleaning is best booked for the holidays.

The process
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and hand over the paperwork. The visit itself takes one overnight shift for many single units, with bigger plant phased. Visits to a place like Osney are planned ahead, so we arrive with what the survey says the job needs.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any parking or loading restrictions
- Find the previous report, if there is one

Advice
Different parts, different methods
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
What affects the quote in Osney
Sites vary more than people expect. What affects the quote:
- Any permits to work or inductions
- Access, including roofs, risers and ceiling voids
- Where the site is and how we reach it
- When the work can happen, such as evenings, overnight or weekends
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before work begins.

- Close-ups of filters, grilles, hatches or access panels

- The times we could work without disrupting the site
- Wide pictures of the system and the area around it
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Once you have those, call 0345 646 2711, or send details by email.
Osney questions
Can a school’s ventilation in Osney be done out of term time?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 76 schools, colleges and universities with registered kitchens within about a mile and a half of Osney. Send us your term dates when you call 0345 646 2711 or drop us a line, and we will fit the work in.
Do you work in villages like Osney?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
Is a quote from pictures possible?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we are fully insured.
Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Keep the area around the fresh air intake clear
- Diary the inspection date recommended in the report
- Stick to the filter change plan
- Make sure condensate is draining away
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. They belong in the plant or maintenance log.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
