What AHU cleaning looks like in Highmoor
Highmoor is about 39 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours.
If you manage a school such as Stoke Row Church of England School, ventilation cleaning is best booked for the holidays.
Highmoor is about 4 miles north-west of Henley-on-Thames, in Oxfordshire. From the centre of Highmoor to the outskirts, AHU cleaning is available to all kinds of commercial premises, from small sites to large estates. 443 places in Oxfordshire are on our list, from busy centres to quieter spots. We also work in Reading, around 7 miles away.
Work in RG9 is surveyed, quoted and booked the same way as anywhere else. That includes premises on The Glebe and Holly Close and nearby roads. Other places close to Highmoor include Highmoor Cross (1 mile south-east), Shepherd's Green (1 mile south-east), Catslip (1 mile north-east), Nettlebed (2 miles north) and Kingwood Common (2 miles south).

AHU cleaning for kitchens and businesses in Highmoor
Where a building in Highmoor has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. Typical jobs include dirty fans and fan housings and condensate trays that won’t empty, across heating and cooling coils, supply and extract fans and drain trays.
Work in a small place like Highmoor starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

The process
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, and that takes half a day to a full day per unit, with large plant planned over several shifts. A quick note on how to find the site and where to park makes a visit to Highmoor run smoothly.
- 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.
- We take after photos and issue the certificate and report.
How to prepare
- Let us know about parking and loading
- Agree a time when the area can be out of use
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

What the work involves, part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
FAQs for Highmoor
Is Highmoor in your area for AHU cleaning?
Yes. We work across London and the South East, and Highmoor is part of that. Get in touch with the details and we’ll arrange a survey.
Do you work in villages like Highmoor?
Yes. Villages and rural sites across the South East are part of our work, Highmoor included. Photos of the system and directions to the site help us plan the visit.
What if parts of the system can’t be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
Are you fully insured?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
How do you protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
Common problems we fix in Highmoor
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Highmoor, that’s air they breathe for hours at a time.
Any of these means the system needs a check-up:
- Air handling units due a clean after building work
- Odours coming through the supply air
- Condensate trays that won’t empty
- Coils clogged with dust and debris
In Highmoor, we look inside the system before deciding what needs cleaning.

How we price AHU cleaning
There’s no set price list, because sites vary so much. The quote depends on:
- Working hours and out-of-hours timing
- A single visit or a regular plan
- Access, including roofs, risers and ceiling voids
- Site rules, permits and inductions
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before work begins.
Asking for a quote
When you call or email, these details help:
- Close-ups of filters, grilles, hatches or access panels
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Wide pictures of the system and the area around it
We do not publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To start, call 0345 646 2711, or email photos.

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.
Staff cleaning and specialist work aren’t the same thing. 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. Reaching it takes a specialist with the right equipment.
Between visits
Aftercare is simple, and it helps at the next visit:
- Report water on the plant room floor
- Do not store bins or materials near the intake
- Keep the certificate and photo report with the plant records
- Book the next check in line with the report
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
