Ventilation in Coscote buildings
Going by the FSA’s register, there are about 6 schools, colleges and universities and about 6 care, childcare and hospital premises serving food in and around Coscote, up to about a mile and a half out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Coscote, about 50 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible. For Coscote, the closest hospital is Abingdon Community Hospital, roughly 5.8 miles north. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Abingdon Community Hospital, about 5.8 miles north, is the nearest hospital to Coscote, and healthcare sites of every size need their supply air kept clean. Wherever a school like Hagbourne Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Coscote is about 1 mile south of Didcot, in Oxfordshire. Coscote gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with photos.

Around Coscote
Typical jobs here are in premises near UTC Oxfordshire, Fleur De Lys Public House and St Birinus School and the streets around them. The closest station to Coscote is Didcot Parkway station, roughly 1.5 miles north of the centre. Other landmarks nearby include Brightwell Castle (4.1 miles east) and Atlas Computer Laboratory (2.8 miles south-west). For a walk, there’s Mowbray Fields and Churn Hill.
How we handle AHU cleaning in Coscote
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. If you have dirty fans and fan housings and dirty filters cutting the airflow, we can help, from internal panels, filter sections and dampers and louvres onwards.
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.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What else we do in Coscote
What affects the quote in Coscote
A fixed price needs a few facts first. We check:
- Any permits to work or inductions
- The size of the system
- What state the system is in
- A single visit or a regular plan
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711 or use the quote form, and we’ll talk you through it.
What to send for a quote
To help us quote quickly, send us:
- The paperwork from the last visit, if you have it
- The site address and the type of premises
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
Need a price for AHU cleaning? Please phone us on 0345 646 2711 or email us with a few details about the site. We’ll talk you through the work and give you a fixed quote before anything is booked.
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Make sure the unit’s access doors open easily
- Report musty smells from the vents right away
- Diary the inspection date recommended in the report
- File each AHU report in the maintenance log
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
How the visit works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work 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 Coscote can be planned properly.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Find the previous report, if there is one
- Mention any locked doors, roof access or ceiling voids
- Clear the space around the work
How to get a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.

Coscote: your questions answered
Can ventilation in schools around Coscote be cleaned out of term?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 6 schools, colleges and universities with registered kitchens within about a mile and a half of Coscote. Tell us your holiday dates and we will book the visit for when the site is empty.
Can the work in Coscote be done at night or at weekends?
Yes, we can come after you close and finish before you open. It means the site in Coscote keeps running as normal. Tell us your opening hours when you ask for a quote.
Do you look at the system first?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
How much does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, call 0345 646 2711 or email us with the site type, opening hours and a few pictures.
How long does it take to clean an air handling unit?
The work takes one overnight shift for many single units, with bigger plant phased. Large plant can be split over several shifts, so call us on 0345 646 2711 or email us to talk it through.
Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Staff cleaning and specialist work are not the same thing. 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.
Why it’s worth doing now in Coscote
Stuffy rooms and stale smells in a building in Coscote can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. It’s worth booking a check, because nobody sees inside a duct day to day.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before work begins.

What the work involves, part by part
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
