Managing agents and facilities teams in Bladon
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
We also work for facilities teams across offices, schools and healthcare in Bladon and across Oxfordshire. Larger estates can be phased building by building around the people who use them.
AHU cleaning in Bladon
If the units serving a building in Bladon have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. If you have plant that has been serviced but not cleaned and plant that needs cleaning after a refit, we can put it right, from dampers and louvres, filter sections and supply and extract fans 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.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Check the drain tray is emptying during routine visits
- Diary the inspection date recommended in the report
- Change filters on schedule and log each change
- Report musty smells from the vents straight away
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
When it’s something else
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It does not solve:
- Damaged coils beyond cleaning
- Breakdowns that need a mechanical engineer
- Controls and BMS settings that run the unit
If in doubt, ring 0345 646 2711 or email us and we will say what we think.

Bladon buildings and their air
Food Standards Agency data includes about 5 care, childcare and hospital premises and about 6 hotels, B&Bs and guest houses within about 1.5 miles of central Bladon. Busy, occupied buildings like these are where clean supply air matters most. About 58 miles out from central London, Bladon is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
School buildings such as Bladon Church of England Primary School are typically done in the holidays, so classrooms aren’t disturbed.
Bladon is about 7 miles north-east of Witney, in Oxfordshire. Anywhere in OX20, we can carry out AHU cleaning at your premises. Our Oxfordshire coverage runs to 443 places, Bladon among them. There’s also a page for Oxford, about 7 miles away.
We work across OX20 for AHU cleaning and the roads nearby. If you need AHU cleaning at premises on The Green, Park Street and Lamb Lane or anywhere close by, we can help. If your site is just outside Bladon, we cover Woodstock (1 mile north), Begbroke (1 mile east), Church Hanborough (2 miles south-west), Long Hanborough (2 miles west) and Thrupp (2 miles east). Within a short drive, we also cover Oxford (7 miles south-east), Bicester (10 miles north-east), Abingdon-on-Thames (11 miles south), Witney (7 miles south-west), Carterton (11 miles south-west) and Kidlington (3 miles east).
Around Bladon
Locally, jobs take us to businesses close to The White House and The Marlborough Church of England School. The nearest railway station is Hanborough station, about 1 mile west of the centre. Nearby you will also find Oxford Bus Museum (1 mile west). Not far away are Hook Meadow and The Trap Grounds.
Part by part
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with pictures so you can decide on any repairs.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Do you need AHU cleaning in Bladon?
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
The symptoms we are asked about most include:
- Debris and leaves in the fresh air intake
- Rooms that smell stuffy when the system runs
- Dirty fans and fan housings
- Plant that needs cleaning after a refit
For buildings in and around Bladon, TR19® Air cleaning starts with an inspection.

What else we do in Bladon
Bladon questions
Do you offer AHU cleaning in Bladon?
Yes, Bladon is covered. Get in touch with the details and we will arrange a survey.
Do you work overnight in Bladon?
Yes, out-of-hours work is a big part of what we do. It means the site in Bladon keeps running as normal. Tell us your opening hours when you ask for a quote.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Can you clean the ducts connected to the AHU?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where necessary.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with photos where it helps.
Do you have insurance?
Yes, we are fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
What about areas you can’t get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
How the visit works
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 the rest is down to us. Afterwards, the area is left tidy and the written report follows. A quick note on how to find the site and where to park makes a visit to Bladon run smoothly.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us the best time to work, such as after service or at a weekend
- Allow time for equipment near the work to be turned off and cool down
