AHU cleaning for kitchens and businesses in Tilford Common
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. The work covers heating and cooling coils, dampers and louvres and internal panels, and common reasons people get in touch are dirty filters cutting the airflow and dust-coated heating and cooling coils.
In a village or hamlet like Tilford Common, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Tilford Common questions
Is AHU cleaning available in Tilford Common?
Yes, we work in Tilford Common and the places around it. A fixed quote typically follows within one working day of the survey details.
Do you work overnight in Tilford Common?
Yes, nights and weekends are routine for us. The work in Tilford Common can fit around your hours. Your opening times are the first thing we ask for.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We don’t leave it behind.
Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
What if parts of the system cannot be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
How much does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.

How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes half a day to a full day per unit, with large plant planned over several shifts. In a small place like Tilford Common, the journey is planned ahead and the visit arranged around the site’s hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Tell us the best time to work, such as after service or at a weekend
- Find the previous report, if there is one

What else we do in Tilford Common
Signs you need AHU cleaning in Tilford Common
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Any of these means the system needs a check-up:
- Fan sections that haven’t been cleaned in years
- Rooms that smell stuffy when the system runs
- Air handling units with blocked filters
- Coils clogged with dust and debris
Wherever a school like All Saints CofE Aided Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Before you book anyone
- How they set the interval to the next visit
- What hours they’ll be on site
- Whether they’re fully insured
- Whether inaccessible sections are listed on the report
What a clean won’t put right
We’d rather tell you now than book work that will not help, so here are the limits:
- Breakdowns that need a mechanical engineer
- Building management system faults
- Dirty ducts beyond the unit itself
If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think before you book.
What the work covers
- Internal panels
- Filter sections
- Dampers and louvres
- Drain trays
- Heating and cooling coils
- Supply and extract fans
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Clear leaves and litter away from the intake
- Book the next check in line with the report
- Change filters on schedule and log each change
- Make sure the unit’s access doors open easily
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
What the work involves, part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
