For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
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.
Ventilation duct cleaning in Cannon Hill, done properly
We get into the ducts through access panels at intervals along the system. Where there are not enough panels to reach every section, we note the uncleaned parts in the report, and new access panels can be installed for the next clean. The work covers toilet extract systems, general extract ductwork and supply ductwork, and people most often call us about musty smells from the ventilation and toilet and washroom extracts full of fluff.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in Cannon Hill.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What affects the cost of ventilation duct cleaning
Your quote is based on your site. We take into account:
- How many systems or sites are involved
- One-off work versus a regular cycle
- The size of the system
- Site requirements such as sign-in and permits
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before we start.
What to send for a quote
We can often survey from pictures. The most useful are:
- Detail shots of panels, filters and grilles
- The postcode and the type of business
- Any symptoms, from odd noises to smells or leaks
- When the site is open and when it’s quiet
Getting a quote doesn’t take long. Call or email with a few details and you will typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Cannon Hill buildings and their air
There are about 34 schools, colleges and universities, about 42 hospitals, care homes and childcare premises and about 4 hotels and guest houses on the FSA’s food hygiene register within 1.5 miles or so of the middle of Cannon Hill. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Cannon Hill’s nearest hospital, St. Anthony's Hospital, is about 1.5 miles south. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. In London, ventilation plant is often on the roof or below ground, so the work is usually done out of hours.
If you manage shops or offices close to South Merton station, a TR19® Air inspection shows whether the ductwork needs cleaning. St. Anthony's Hospital, about 1.5 miles south, is the nearest hospital to Cannon Hill, and healthcare sites of every size need their supply air kept clean. Wherever a school like Hillcross Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Cannon Hill questions
Can a school’s ventilation in Cannon Hill be done out of term time?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 34 schools, colleges and universities with registered kitchens within about a mile and a half of Cannon Hill. Just give us a ring on 0345 646 2711 or email us with your term dates and we will plan around them.
Does London parking affect a job in Cannon Hill?
A loading bay, a visitor permit or off-street space near the site in Cannon Hill makes the visit easier to plan. Working overnight, as we often do in London, normally makes it simpler.
What about areas you can’t get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Can you quote from photos?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
Do you work in Cannon Hill?
Yes. We work in Cannon Hill and across Greater London, as part of our work across South East England and London. To book, ring 0345 646 2711 or drop us a line.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Every site has its own report.
Do you provide a report?
Yes, a TR19® certificate and pictures. It also notes unreached sections and a recommended next inspection.
When should our ventilation next be cleaned?
That varies with the building, the filters and how hard the system works. Regular inspection tells you when it’s due.
What happens if it’s left?
In healthcare, care and education settings, ventilation cleaning is hard to put off. Clean ducts are part of providing good air for the people inside. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.

The process
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes a weekend for a modest system, with large buildings phased floor by floor, and we clear up before we go. A name and number for whoever controls access to the building in Cannon Hill saves time on the night.
- First the system is surveyed, on site or from photos and drawings.
- Inspection comes next, with photos of the inside of the ducts.
- We protect the rooms beneath and switch the system off.
- We clean the ductwork, grilles and diffusers through access panels.
- A certificate and before and after pictures follow, with anything not reached recorded.
Getting ready for the visit
- Agree a time when the area can be out of use
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload

How the job changes from site to site
Supply ductwork
Supply runs are inspected at set points first to see where cleaning is needed.
Offices and retail
Refits in commercial space often leave construction dust in the ducts. A clean before handover is a sensible step.
What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Diary the next TR19® Air inspection
- Report leaks or damp near ceilings and risers
- Wipe grilles and diffusers during routine cleaning
- Report dust blowing from grilles straight away
Keep up with filter changes to protect the ducts. Overdue filters let dust straight back in.
Do not let construction dust into the ventilation by turning it off or covering the openings.
