Managing agents and facilities teams in Chipping Norton
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
We also work for facilities teams across offices, schools and healthcare across Oxfordshire. Work can be phased by floor, building or site to keep disruption down.
AHU cleaning in Chipping Norton, done properly
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. The work covers heating and cooling coils, drain trays and filter sections, and common reasons people get in touch are dust built up on fan impellers and units that have only ever had filter changes.
In a place like Chipping Norton, air handling units are often tucked into roof spaces or small plant rooms, 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 pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Questions from Chipping Norton
Do you work at weekends in Chipping Norton?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Chipping Norton needn’t be disturbed. Just call us on 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Can a school’s ventilation in Chipping Norton be done out of term time?
Yes, and it’s the easiest time to do it. There are about 5 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Chipping Norton. Booking early in the term gives the best choice of holiday dates.
What do you need from me for a quote?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then ring 0345 646 2711, or send details by email.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. For a quote, give us a ring on 0345 646 2711, or email photos and tell us about the site and its opening hours.
How far ahead should we book?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Is a quote from pictures possible?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and we usually come back within one working day. Some sites still need a visit, and we will say so.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Leave it or put it right?
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. It’s easy to lose track of when the work was last done on a quieter site.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.
Why book with us

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, which 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.
When to call us in Chipping Norton
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
If you notice any of these, it’s worth a diagnosis:
- Fan sections that haven’t been cleaned in years
- Intake sections clogged with outdoor debris
- Coils clogged with dust and debris
- Odours coming through the supply air
For schools like Chipping Norton School, the holidays are the usual time to inspect and clean ventilation.
What your quote should include
- Whether the figure could change on the day
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- How they set the interval to the next visit
- Whether the work can be done while the site is closed

Around Chipping Norton

Chipping Norton’s nearest station is Kingham station, about 4.4 miles south-west of the centre. A little further out are Wheelbarrow Castle (3.9 miles north-west) and Chipping Norton Museum (under half a mile north-east).
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Report musty smells from the vents straight away
- Clear leaves and litter away from the intake
- Book the next check in line with the report
- Watch for drips or damp patches near the plant
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
When it’s something else
Before you book, it helps to know what’s not included:
- Ductwork downstream of the unit, which is a separate clean
- Damaged coils beyond cleaning
- Airflow problems caused by the system’s design
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we will tell you honestly before booking.

How it works
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. Everything the job in Chipping Norton needs is worked out beforehand, from the survey.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Find the previous report, if there is one
- Tell us about site rules, permits or sign-in
- Mention any locked doors, roof access or ceiling voids
Getting a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
