AHU cleaning in Somerton
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from photos or a site visit, and send you a fixed quote before any cleaning starts. Common call-outs are for drain trays holding standing water and dirty filters cutting the airflow, across internal panels, supply and extract fans and dampers and louvres.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Signs you need AHU cleaning in Somerton
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
Look out for these warning signs:
- Air handling units never cleaned inside
- Dust built up on fan impellers
- Rooms that smell stuffy when the system runs
- Dirty filters cutting the airflow
Whether the building is in Somerton itself or nearby, filters, coils, drain trays and ducts are all part of the work.
What your quote should include
- What paperwork you get at the end
- Whether the figure could change on the day
- Whether VAT is included
- How areas they can’t reach will be recorded
For landlords and multi-site operators
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, and that takes one overnight shift for many single units, with bigger plant phased. For a village or hamlet like Somerton, tell us about narrow lanes, gates and parking when you book.
- 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.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive
- Find the previous report, if there is one

What affects the cost of AHU cleaning
The price is fixed before any work begins. It’s based on:
- Site requirements such as sign-in and permits
- Whether it’s a one-off visit or part of a schedule
- The condition we find in the survey
- How easy every part is to reach
The cost depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
- Wide photos of the system and the area around it
- The times we could work without disrupting the site
To help us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Once you have those, call 0345 646 2711 or email us.
Why deal with it now?
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Equipment tucked in a roof space or outbuilding near Somerton rarely gets looked at unless someone books it.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, ring 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.

When something else is needed
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- Building management system faults
- Mechanical faults with motors, belts or bearings
- Ductwork downstream of the unit, which is a separate clean
If in doubt, call 0345 646 2711 or drop us a line and we will say what we think before booking.

Can you price the work without visiting?

Do you look at the system first?

What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we will typically reply within one working day.
How much notice do you need?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
How often should an air handling unit be cleaned?
That is set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Between visits
Results last longer with the right care. Here’s what we suggest:
- Do not store bins or materials near the intake
- Watch for drips or damp patches near the plant
- Book the next check in line with the report
- Report stiff or damaged access doors
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
