Managing agents and facilities teams in Compton
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
AHU cleaning for kitchens and businesses in Compton
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. We are often asked to deal with odours coming through the supply air and drain trays holding standing water, on heating and cooling coils, internal panels and dampers and louvres.
Work in a small place like Compton starts with agreeing access and timings.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What we do, step by step
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. Visits to a village like Compton are booked in advance, at a time that suits whoever runs the site.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Allow time for equipment near the work to be turned off and cool down
- Agree a time when the area can be out of use

In-house cleaning or a specialist?
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.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Questions from Compton
Can you get to a site in Compton?
Yes, Compton is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can a school’s ventilation in Compton be done out of term time?
Yes, and it’s the easiest time to do it. There are about 9 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Compton. Booking early in the term gives the best choice of holiday dates.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Do you survey before quoting?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with the details in the report.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after pictures. They’re worth keeping with the plant records.
Do you do ventilation duct cleaning too?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
Between visits
To keep the system working properly between visits:
- Keep inspection doors on the unit in good order
- Don’t store bins or materials near the intake
- Report musty smells from the vents right away
- Keep filter changes on time and recorded
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
Ventilation in Compton buildings
Food Standards Agency records list about 9 schools, colleges and universities, about 12 caring premises (care homes, nurseries and hospitals) and about 4 hotels and B&Bs registered as food businesses across Compton and its immediate surroundings (about a mile and a half). Busy, occupied buildings like these are where clean supply air matters most. Compton, about 35 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours.
Ventilation work in and around Compton is risk-based: inspect, then clean what needs it. School buildings such as South Farnham School are usually done in the holidays, so classrooms aren’t disturbed.

How we price AHU cleaning
The quote reflects the site in front of us. We take into account:
- Travel, parking and unloading
- How many systems or sites are involved
- What state the system is in
- Access, including roofs, risers and ceiling voids
What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
Helping us quote
Before you ask for a quote, gather:
- Your opening hours and when the area is out of use
- Wide photos of the system and the area around it
- Problems your staff have spotted
- Any access panels or hatches you can see
To help us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then ring 0345 646 2711, or send details by email.
When it’s something else
Not every problem is solved by AHU cleaning, and we’ll tell you before any work starts. It won’t put right:
- Controls and BMS settings that run the unit
- Mechanical faults with motors, belts or bearings
- Coils that are corroded or leaking and need replacing
Not sure which it is? You can call us on 0345 646 2711, or email photos and we’ll tell you honestly.
What the work covers
- Dampers and louvres
- Filter sections
- Drain trays
- Internal panels
- Heating and cooling coils
- Supply and extract fans
How the job changes from site to site
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.
