AHU cleaning for kitchens and businesses in Britwell Salome
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. We’re often asked to deal with odours coming through the supply air and filters that are clogged or overdue, across drain trays, heating and cooling coils and supply and extract fans.
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.
Each 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.

Staff cleaning versus specialist work
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. Reaching it takes a specialist with the right equipment.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Questions from Britwell Salome
Do you offer AHU cleaning in Britwell Salome?
Yes, Britwell Salome is within the area we cover across London and the South East. You can call 0345 646 2711 or send us an email and let us know what needs doing.
Is Britwell Salome within the area you cover?
Yes, we work in villages as well as towns, and Britwell Salome is covered. Just mention lanes, gates or anything else about the site when you book.
Do you survey before quoting?
Yes. We always survey first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
When should our AHU next be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. At the end, the area is cleaned down.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
Do you offer emergency callouts?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Do you need AHU cleaning in Britwell Salome?
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
Most sites get in touch when they notice something like this:
- Dust-coated heating and cooling coils
- Rooms that smell stuffy when the system runs
- Dirty fans and fan housings
- Leaves and litter drawn into the unit
If you manage a school such as Icknield Community College, ventilation cleaning is best booked for the holidays.

Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare across Oxfordshire. Larger estates can be phased building by building to keep disruption down.
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 the report can go to both.
How the visit works
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and the area is cleaned down before we leave. For a village or hamlet like Britwell Salome, tell us about narrow lanes, gates and parking when you book.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Name a contact who can let us in at the agreed time
- Tell us the best time to work, such as after service or at a weekend
- Mention any parking or loading restrictions
How to get a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.

What the work involves, part by part
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Honest limits
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- The supply and extract ducts, quoted separately
- Damaged coils beyond cleaning
- Controls and BMS settings that run the unit
If in doubt, give us a ring on 0345 646 2711, or send details by email and we’ll say what we think.
