How we handle AHU cleaning in Limehouse
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers supply and extract fans, drain trays and heating and cooling coils, and common reasons people get in touch are intake sections clogged with outdoor debris and stale or musty smells from the ventilation.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. In Limehouse, as elsewhere, cleaning starts with an inspection of what’s there.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Fixed quotes for AHU cleaning in Limehouse
There’s no set price list, because no two systems are the same. The quote depends on:
- The number of sites or systems
- The size of the system
- How easy every part is to reach
- The condition of the system
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.
What we need to know
You do not need the technical terms. It helps if you can send:
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet

To help us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Once you have those, call 0345 646 2711, or email photos.
How the job changes from site to site
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Limehouse buildings and their air
The FSA’s food hygiene register lists about 93 schools, colleges and universities, about 55 care, childcare and hospital premises and about 16 hotels and guest houses with registered kitchens or food service in Limehouse and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. St Clement's Hospital is the nearest hospital, about 0.7 miles north of Limehouse. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Ventilation cleaning in London buildings is usually planned for evenings or weekends.
School buildings such as Stepney Greencoat Church of England Primary School are normally done in the holidays, so classrooms aren’t disturbed. For workplaces around Limehouse station with mechanical ventilation, cleaning can be done in the evening or at weekends. Healthcare buildings such as St Clement's Hospital, about 0.7 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near Limehouse, yours matters too.

Keeping the system healthy
After the visit, a few habits help the work last:
- Keep inspection doors on the unit in good order
- Book the next check in line with the report
- Store the TR19 paperwork where auditors can find it
- Keep the area around the fresh air intake clear
Stick to the filter change schedule, 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. A drain that’s cleared early never gets to the slime stage.
Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
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.
