Ventilation in Clare Market buildings
Food Standards Agency records list about 85 schools, colleges and universities, about 51 care, childcare and hospital premises and about 233 hotels and guest houses registered as food businesses in Clare Market 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 Philip's Hospital is the nearest hospital, about less than half a mile north-west of Clare Market. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Ventilation cleaning in London buildings is normally planned for evenings or weekends.
If you manage shops or offices close to London Charing Cross station, a TR19® Air inspection shows whether the ductwork needs cleaning. If you manage a school such as St Clement Danes CofE Primary School, ventilation cleaning is best booked for the holidays. If you run a surgery, dental practice or care home near Clare Market, clean ventilation matters as much to you as to a hospital like St Philip's Hospital (about less than half a mile north-west).

How we handle AHU cleaning in Clare Market
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. Common call-outs are for coils clogged with dust and debris and intake sections clogged with outdoor debris, on drain trays, supply and extract fans and filter sections.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. In Clare Market, as elsewhere, cleaning starts with an inspection of what’s there.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Different parts, different methods
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
Why it’s worth doing now in Clare Market
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in Clare Market simpler. A booked night’s work in Clare Market costs you no trading time; an unplanned closure does.
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, call us on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.

Clare Market questions
Do you work overnight in Clare Market?

Can you clean school ventilation in Clare Market during the holidays?

What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before we start.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do you have insurance?
Yes. We are fully insured, and we can share the details when you need them.
Can you fix a faulty AHU?
We clean the unit and flag faults rather than repair them, with the details in the report.
What if parts of the system can’t be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.
What affects the quote in Clare Market
The diagnosis comes before the price. The main factors are:
- How many systems or sites are involved
- Access, including roofs, risers and ceiling voids
- Site requirements such as sign-in and permits
- Parking and loading at the site
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.
What we need to know
We can often survey from pictures. Try to include:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
- The paperwork from the last visit, if you have it
Need a price for AHU cleaning? Please give us a ring on 0345 646 2711 or email us with a few details about the site. We’ll talk you through the work and send you a fixed quote before anything is booked.
What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes half a day to a full day per unit, with large plant planned over several shifts. In Clare Market, as across London, we usually work overnight or at weekends and hand the site back ready to open.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Name a contact who can let us in at the agreed time
- Tell us where we can park and unload
- Mention any sign-in, permit or induction we need
How to get a quote
For a fixed quote, call 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
Related advice
Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep the certificate and photo report with the plant records
- Make sure the unit’s access doors open easily
- Don’t ignore odours coming through the grilles
- Book the next check in line with the report
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.

For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building around the people who use them.
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
