How we handle AHU cleaning in Hanover
Our AHU cleaning covers sites in Hanover and the rest of Brighton and Hove, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers dampers and louvres, filter sections and drain trays, and common reasons people get in touch are debris and leaves in the fresh air intake and filters that are clogged or overdue.
In a place like Hanover, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes from a few hours for a compact unit to a day or more for a large one. In a place like Hanover, we fit the visit around your hours.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Agree a time when the area can be out of use
- Dig out any earlier paperwork for the system

Do you need AHU cleaning in Hanover?
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Keep an eye out for any of the following:
- Plant that needs cleaning after a refit
- Dust built up on fan impellers
- Units that have only ever had filter changes
- Coils clogged with dust and debris
Classrooms and halls at schools such as Elm Grove Primary School are easiest to work in when pupils are away.

- Whether the quote shows VAT
- What insurance they carry

Managing agents and facilities teams in Hanover
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
What affects the cost of AHU cleaning
We don’t publish a price list, because no two systems are the same. What we look at:
- The number of sites or systems
- The size of the system
- Site requirements such as sign-in and permits
- Working hours and out-of-hours timing
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
Helping us quote
Before you ask for a quote, gather:
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
- A few general shots of the system
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, ring 0345 646 2711 or send us an email.

Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Keep the area around the fresh air intake clear
- Make sure condensate is draining away
- Keep inspection doors on the unit in good order
- Do not ignore odours coming through the grilles
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
What a clean will not put right
Some problems need a different service or another trade:
- Problems with the unit’s controls or sensors
- Airflow problems caused by the system’s design
- Ductwork downstream of the unit, which is a separate clean
If in doubt, phone us on 0345 646 2711, or send details by email and we’ll say what we think before you book.
