AHU cleaning in Bloomsbury, done properly
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. Typical jobs include dirty fans and fan housings and plant that has been serviced but not cleaned, across supply and extract fans, drain trays and heating and cooling coils.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Bloomsbury, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Report water on the plant room floor
- Stick to the filter change plan
- Make sure condensate is draining away
- Keep the certificate and photo report with the plant records
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.

Staff cleaning versus specialist work
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
How it works
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, and the sign-off is a written report with pictures. The middle part takes longest, and that takes a single shift for a typical unit, longer for large or heavily soiled ones. In a London area like Bloomsbury, parking, loading and building access are planned before the day of the work.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Arrange a key holder or contact on site
- Tell us the best time to work, such as after service or at a weekend
How to get a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Why deal with it now?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. Every month a London system goes without attention adds to what has to be done later.
We do not 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.
Why us?
- Every job surveyed first
- A written report with photos after every visit
- Accredited under CHAS and SafeContractor, with ISO 9001
- Fixed quotes, usually within one working day

FAQs for Bloomsbury
Can you clean school ventilation in Bloomsbury during the holidays?
Yes. The holidays are the usual time for school work. Around Bloomsbury, the Food Standards Agency lists about 66 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Can parking be tricky for a job in Bloomsbury?
Tell us where a van can stop near your site in Bloomsbury, and about any building rules on loading. If the building has a loading slot system, we will book into it.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. At the end, the area is cleaned down.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What happens to the waste?
We take it away at the end of the visit. During the work, it’s contained so the area stays clean.
Can you set up regular visits?
Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
Common problems we fix in Bloomsbury
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
What we’re most often called out for:
- Dirty filters cutting the airflow
- Dirty fans and fan housings
- Rooms that smell stuffy when the system runs
- Drain trays holding standing water
For workplaces around London Euston station with mechanical ventilation, cleaning can be done in the evening or at weekends.

What AHU cleaning looks like in Bloomsbury
The FSA’s food hygiene register lists about 66 schools, colleges and universities, about 58 caring premises (care homes, nurseries and hospitals) and about 206 hotels and guest houses with registered kitchens or food service within roughly a mile and a half of the centre of Bloomsbury. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About within half a mile south-east of Bloomsbury is National Hospital for Neurology and Neurosurgery, the nearest hospital. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. London plant rooms are often on roofs or in basements reached through occupied floors.
Healthcare ventilation, from large hospitals like National Hospital for Neurology and Neurosurgery (about within half a mile south-east) to small clinics, depends on clean filters, coils and ducts. Wherever a school like UCL School of Slavonic and East European Studies has ducted ventilation, a half-term visit keeps the work out of lesson time.
Bloomsbury is about 1 mile north-east of City of Westminster, in Greater London. Sites in Bloomsbury get the same service as everywhere we cover: a survey first, a fixed quote, work timed around your hours and a report with pictures. Our area takes in 764 places across Greater London, from busy centres to quieter spots.
