Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
We also work for facilities teams across offices, schools and healthcare in Round Bush and across Hertfordshire. Larger estates can be phased building by building around the people who use them.
About our AHU cleaning in Round Bush
If the units serving a building in Round Bush have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you have filters that are clogged or overdue and air handling units due a clean after building work, we can put it right.
In a village or hamlet like Round Bush, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Every visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What AHU cleaning looks like in Round Bush
Food Standards Agency records list about 8 schools, colleges and universities and about 4 hotels and B&Bs registered as food businesses in Round Bush and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. We cover Round Bush, about 16 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours.

How we price AHU cleaning
You will get a fixed price before work begins. It takes into account:
- The size of the system
- Whether we need access equipment or extra panels
- The number of sites or systems
- Any permits to work or inductions
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, call us on 0345 646 2711, or send details by email for straight advice and a fixed quote.
Helping us quote
When you call or email, it’s useful to have:
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
- How we’d reach plant on a roof or in a plant room
We don’t publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To start, ring 0345 646 2711, or email photos.
What the work involves, part by part
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Why deal with it now?
Stuffy rooms and stale smells in a building in Round Bush can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. A fault that closes a site in a village like Round Bush affects everyone who depends on it.
Kitchens, offices, schools and hospitals are all priced 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.

The process
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. Pictures of the system and its access let us plan the work in Round Bush before we set off.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Tell us about site rules, permits or sign-in
- Move anything stored near the system
- Mention any locked doors, roof access or ceiling voids

Advice
Questions from Round Bush
Do you work overnight in Round Bush?
Yes, nights and weekends are routine for us. That way a site in Round Bush doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Do you clean school ventilation in Round Bush in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Round Bush, the Food Standards Agency lists about 8 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then ring 0345 646 2711 or use the quote form.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
When should our AHU next be cleaned?
That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
How much does AHU cleaning cost in Round Bush?
It depends on the site, so we quote each one individually. For a quote, call 0345 646 2711 or email us and tell us about the site and its opening hours.
Are you fully insured?
Yes. Full insurance covers our work and have been trading since 2009.
Where does the waste go?
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.
Honest limits
AHU cleaning cannot fix everything, and we’ll tell you before work begins. It does not solve:
- Building management system faults
- Ventilation that was badly designed in the first place
- Dirty ducts beyond the unit itself
If you are not sure, just call 0345 646 2711 or email us and we’ll give you a straight answer.
What we work on in Round Bush
- Supply and extract fans
- Drain trays
- Internal panels
- Filter sections
- Heating and cooling coils
- Dampers and louvres
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Make sure the unit’s access doors open easily
- Do not ignore odours coming through the grilles
- Note any water around the unit or leaks below it
- Look at the condensate drain whenever the unit is serviced
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.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
