Ventilation duct cleaning for kitchens and businesses in Southgate
In a building in Southgate, the people inside spend hours breathing what the ventilation delivers. Clean ducts are part of a healthy building, alongside filter changes and AHU maintenance. Typical jobs include extract ducts clogged with lint and dust and rooms that feel airless when the system runs, on hospitals and care homes, offices and schools and supply ductwork.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Southgate is normally planned out of hours. Loading and parking are planned with the building first.
We’re 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’ve been trading since 2009.

Part by part
Grilles and diffusers
Every duct ends at a grille or diffuser in the room. We clean them as part of the job, so the room side matches the duct side.
Extract ductwork
Toilet and washroom extract can carry moisture as well as dust, which makes dirt stick. They’re cleaned and their condition recorded.
Why act early in Southgate
Smells, dust around grilles and stuffy rooms are signs the system needs attention. Acting early keeps the clean simpler. Every month a London system goes without attention adds to what has to be done later.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

- One number for every site across the South East and London
- BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease

What else we do in Southgate
What your team can do, and what needs us
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
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. That part needs specialist access and equipment.
Southgate questions
Can you come to Southgate after we close?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Your opening times are the first thing we ask for.
Do you clean school ventilation in Southgate in the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 52 schools and colleges with food registrations within roughly a mile and a half of Southgate. You can give us a ring on 0345 646 2711 or send us an email with the dates the site is empty.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Each site gets its own report and pictures.
Do we need to close while you work?
Not typically. The area we are working in has to be out of use while we are there, so the visit goes in a quiet slot.
When should our ventilation next be cleaned?
It depends on the building, how the system is used and what inspection finds. Regular inspection tells you when it’s due.
How long does ventilation cleaning take?
As a guide, it takes a shift or two for a small system, longer for a whole building. Large buildings can be phased, often out of hours, to fit around the building.
What happens if parts of the ductwork cannot be reached?
Those sections are recorded as not cleaned in the report, so it’s clear what’s outstanding. New access panels can be installed so they’re covered next time.
Does the law say we must follow TR19?
No. TR19® itself isn’t law; it’s a BESA specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
What we are called out for in Southgate
Planned maintenance tends to focus on fans and filters, not the ducts. Plant can be well serviced while the ductwork goes untouched for years.
The symptoms we’re asked about most include:
- Dirty diffusers dropping dust into rooms
- Damp or stale smells from grilles
- Ventilation that needs a TR19® Air inspection
- Toilet and washroom extracts full of fluff
School buildings such as Ashmole Primary School are usually done in the holidays, so classrooms aren’t disturbed.

What we work on in Southgate
- Toilet extract systems
- Hospitals and care homes
- Supply ductwork
- Grilles and diffusers
- General extract ductwork
- Offices and schools
The process
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes from one overnight visit to a phased programme over several weeks. We fit London jobs around the building rather than the other way round, so a visit in Southgate is typically out of hours.
- We survey the system from drawings, pictures or a site visit.
- We inspect inside the ductwork at set points and photograph it.
- The area below is protected and the system switched off.
- We clean the ductwork, grilles and diffusers through access panels.
- We issue a TR19® certificate and a photo report listing what was cleaned.
How to prepare
- Name a contact who can let us in at the agreed time
- Find the previous report, if there is one
- Agree a time when the area can be out of use

How we price ventilation duct cleaning
We quote each job individually. This is what makes a difference:
- Site rules, permits and inductions
- Access, including roofs, risers and ceiling voids
- Where the site is and how we reach it
- Whether it’s a one-off visit or part of a schedule
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, ring 0345 646 2711 or email us and we will give you an honest view and a fixed quote.
Asking for a quote
To speed up the quote, please include:
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
- How we’d reach plant on a roof or in a plant room
- Any access panels or hatches you can see
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
