About our AHU cleaning in Bighton
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. The work covers internal panels, supply and extract fans and dampers and louvres, and common reasons people get in touch are filters that are clogged or overdue and plant that has been serviced but not cleaned.
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.
Every visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

How we price AHU cleaning
You’ll get a fixed price before any work starts. It’s based on:
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- The condition we find in the survey
- Site requirements such as sign-in and permits
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before any work starts.
What to send for a quote
There’s no need for technical detail. Just send:
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711 or use the quote form.

Signs you need AHU cleaning in Bighton
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
What we are most often called out for:
- Rooms that smell stuffy when the system runs
- Dirty fans and fan housings
- Plant that has been serviced but not cleaned
- Leaves and litter drawn into the unit
Around Bighton, as anywhere, ventilation cleaning begins with an inspection.
Questions to ask before booking
- If the quote is a fixed price or an estimate
- Whether the quote shows VAT
- How they set the interval to the next visit
- Whether the quote is based on a survey or pictures
What happens if it’s left?
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. If the system at a site near Bighton fails, there may be nowhere nearby to move to.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.

What the work involves, part by part
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.

Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Keep the area around the fresh air intake clear
- Check the drain tray is emptying during routine visits
- Flag stale or damp smells in the supply air
- Diary the inspection date recommended in the report
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
