About our AHU cleaning in Brick End
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. The work covers heating and cooling coils, internal panels and filter sections, and common reasons people get in touch are dust built up on fan impellers and plant that needs cleaning after a refit.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What affects the quote in Brick End
The survey tells us what the work involves. The main factors are:
- Whether it’s a one-off visit or part of a schedule
- How many systems or sites are involved
- The condition of the system
- Any permits to work or inductions
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- Close-ups of filters, grilles, hatches or access panels
- The postcode and the type of business
- The paperwork from the last visit, if you have it
- Problems your staff have spotted

What AHU cleaning can’t fix
Not every problem is solved by AHU cleaning, and we’ll tell you before work begins. It doesn’t solve:
- Coils that are corroded or leaking and need replacing
- Ductwork downstream of the unit, which is a separate clean
- Problems with the unit’s controls or sensors
If you’re not sure, just give us a ring on 0345 646 2711 or send us an email and we’ll give you a straight answer.

What else we do in Brick End
The process
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Seeing the system in photos first means the trip to Brick End can be planned properly.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Let us know when the site is closed or quiet
- Make sure someone can let us in and lock up afterwards
- Plan for cooking equipment or plant to be off before we arrive
How to get a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, call 0345 646 2711 or use the quote form.

How the job changes from site to site
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
Between visits
Aftercare is simple, and it makes the next visit easier:
- Keep the certificate and photo report with the plant records
- Diary the inspection date recommended in the report
- Report musty smells from the vents straight away
- Keep inspection doors on the unit in good order
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. Equipment tucked in a roof space or outbuilding near Brick End rarely gets looked at unless someone books it.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.

Common questions in Brick End
Can you work in Brick End outside opening hours?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Brick End needn’t be disturbed. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
Can you get to a site in Brick End?
Yes, Brick End is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Is a quote from pictures possible?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we normally come back within one working day. Some sites still need a visit, and we will say so.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
How do you protect the area?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
Do you clean the ductwork as well?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, with new panels fitted where needed.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
