Professional AHU cleaning in and around Virginia Water, booked around your opening hours and finished with a written report and pictures.
- Dirty coils holding back the airflow
- Leaves and litter drawn into the unit
- Dirty fans and fan housings
How the visit works
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Your opening hours decide when we come to Virginia Water, not ours.
- The survey covers the unit, its access and how it can be shut down.
- 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.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Let us know when the site is closed or quiet
- Clear loose items from the work area
How to get a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Related advice
AHU cleaning for kitchens and businesses in Virginia Water
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. The work covers drain trays, filter sections and internal panels, and common reasons people get in touch are plant that needs cleaning after a refit and stale or musty smells from the ventilation.
For a building near Virginia Water, the visit is planned around how it’s used, and the journey is planned ahead. The method does not change: inspect first, clean, then record what was done.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Questions from Virginia Water
Do you work overnight in Virginia Water?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Virginia Water needn’t be disturbed. Let us know the hours you’re closed and we’ll book within them.
Do you clean school ventilation in Virginia Water in the holidays?
Yes, out-of-term visits are normal for schools. Around Virginia Water, the Food Standards Agency lists about 7 schools and colleges with registered kitchens within a mile and a half or so. Just call us on 0345 646 2711, or send details by email with your term dates and we’ll plan around them.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
Do you repair air handling units?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
Will we get paperwork for the AHU clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
Is a quote from photos possible?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What types of premises do you cover?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
When something else is needed
A few issues sit outside what this work can do:
- A system that’s undersized for the building
- Ductwork downstream of the unit, which is a separate clean
- Coils that are corroded or leaking and need replacing
If in doubt, call us on 0345 646 2711 or send us an email and we’ll say what we think before you book.
Where we work
- Supply and extract fans
- Heating and cooling coils
- Filter sections
- Dampers and louvres
- Drain trays
- Internal panels
How we price AHU cleaning
The survey tells us what the work involves. The main factors are:
- Whether several sites go on one quote
- Site rules, permits and inductions
- The condition we find in the survey
- Where the site is and how we reach it
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.
Helping us quote
When you contact us, these details help:
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
- The postcode and the type of business
We do not publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To start, call us on 0345 646 2711, or email photos.

What else we do in Virginia Water
Virginia Water buildings and their air
Food Standards Agency data includes about 7 schools, colleges and universities across Virginia Water and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. At about 21 miles from central London, Virginia Water sits well inside the area we cover. Evening, overnight and weekend visits are all possible. About 2.5 miles south-east of Virginia Water is St. Peter's Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Classrooms and halls at schools such as Trumps Green Infant School are easiest to work in when pupils are away. If you run an office near Virginia Water station, its supply ductwork can gather dust for years before anyone looks inside. Hospitals such as St. Peter's Hospital (about 2.5 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Virginia Water are no different.
Virginia Water is about 2 miles south-west of Egham, in Surrey. We carry out AHU cleaning for commercial premises of every kind in Virginia Water and the rest of Surrey. 395 places in Surrey are on our list, large and small. For sites nearby, see our Guildford page, about 11 miles away.
We work across GU25 for AHU cleaning and the roads nearby. That includes premises on Chapel Square, Station Approach and Monks Road and the roads around them.

What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
For landlords and multi-site operators
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Facilities teams in offices, schools and healthcare sites book us too in Virginia Water and across Surrey. Work can be phased by floor, building or site to keep disruption down.
Leave it or put it right?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Light use slows the build-up but does not stop it.
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before any work starts.
