Greater London · Ventilation duct cleaning
Ventilation cleaning in High Barnet
One call covers ventilation duct cleaning in High Barnet, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Ducts that need a clean before handover
- Ductwork never cleaned since it was installed
- Dirty diffusers dropping dust into rooms
Multi-site and managed buildings
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Facilities teams in offices, schools and healthcare sites book us too in High Barnet and across Greater London. Work can be phased by floor, building or site to keep disruption down.
About our ventilation duct cleaning in High Barnet
Everyone in the building breathes the air the ventilation brings in. Clean ducts are part of a healthy building, alongside filter changes and AHU maintenance. If you are dealing with ventilation that needs a TR19® Air inspection and toilet and washroom extracts full of fluff, we can help.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in High Barnet.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Leave it or put it right?
Clean ducts let the air move as designed, which takes strain off the fans. Dirty ducts make the whole system work harder. For a site in High Barnet, fitting the work in overnight now is far easier than closing at short notice later.
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and why the quote is fixed before we start.
Why us?
- Work around your opening hours, with 24/7 emergency cover
- A single point of contact for sites across the South East and London
- Photo reports with every job
- BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease

Different parts, different methods
Schools and colleges
Classrooms full of people, paper and coats produce plenty of dust. Regular inspection keeps on top of it.
Extract ductwork
A dirty extract duct makes its fan work harder. A clean duct takes the load off.
When something else is needed
Before you book, it helps to know what’s not included:
- Damp or mould problems coming from the building fabric
- Cooking extract ducts, which are a separate specialist clean
- Design problems with the ductwork layout
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we will tell you honestly before you book.

- Offices and schools
- Grilles and diffusers

How we price ventilation duct cleaning
Sites vary more than people expect. The main factors:
- Parking and loading at the site
- The condition of the system
- How many systems or sites are involved
- A single visit or a regular plan
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 explain what it covers.
What to send for a quote
There’s no need for technical detail. It helps if you can send:
- The times we could work without disrupting the site
- A few general shots of the system
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
We don’t publish a price list, because every site is different. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.
The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, which takes anything from a single shift for a small office to a planned programme of nights for a large building. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in High Barnet.
- We look at the system and any earlier reports.
- We inspect the ducts at chosen points to see where cleaning is needed.
- We cover the area below and turn off the system.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- We report on the work, listing any inaccessible sections and the next inspection date.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Name a contact who can let us in at the agreed time
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.

Questions from High Barnet
Can a school’s ventilation in High Barnet be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 21 schools, colleges and universities with registered kitchens within about a mile and a half of High Barnet. Send us your term dates when you call us on 0345 646 2711 or use the quote form, and we will fit the work in.
Can parking be tricky for a job in High Barnet?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
How much notice should we give?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
Do you cover High Barnet?
Yes. High Barnet is part of the area we cover, as part of our area across London and the South East.
When should our ventilation next be cleaned?
Inspection should decide it, in line with TR19® Air. Busy or sensitive buildings may need it more often.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Can you look after several sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
Ventilation in High Barnet buildings
The FSA’s food hygiene register lists about 21 schools, colleges and universities and about 26 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service in High Barnet and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. High Barnet’s nearest hospital, Barnet General Hospital, is about 0.5 miles south-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
School buildings such as Foulds School are normally done in the holidays, so classrooms are not disturbed.
