Ventilation cleaning in Smithfield
Ventilation duct cleaning for commercial sites in Smithfield and across Greater London. CHAS, SafeContractor and ISO 9001, and fully insured.

Why act early in Smithfield
If a building in Smithfield has just been refitted, now is the time to clean the ductwork. Otherwise construction dust left in the ducts is blown out once the system runs. Planning ahead in Smithfield lets you pick a quiet night rather than lose a busy one.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, call 0345 646 2711, or send details by email for straight advice and a fixed quote.

Ventilation duct cleaning for kitchens and businesses in Smithfield
A dusty duct in a building in Smithfield is more than an eyesore. It slows the air, strains the fans and can be blown back out of the grilles. A clean puts the system back as it should be. If you have ducts that need a clean before handover and blocked general extract ductwork, we can help.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Smithfield is normally planned out of hours. Parking and loading are agreed with the building in advance.
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.

When to call us in Smithfield
Planned maintenance tends to focus on fans and filters, not the ducts. Plant can be well serviced while the ductwork goes untouched for years.
Signs it’s time to call us include:
- Grilles and diffusers streaked with dirt
- Systems missing access panels
- Systems with no record of inspection or cleaning
- Blocked general extract ductwork
For workplaces around Farringdon station with mechanical ventilation, cleaning can be done in the evening or at weekends.
Questions to ask before you book
- Whether the whole system is included, or only the parts that are easy to reach
- Whether a survey comes first
- Whether inaccessible sections are listed on the report
- What paperwork you get at the end
Part by part
Schools and colleges
Busy classrooms send a lot of dust and fibre into extract ducts. Regular inspection keeps on top of it.
Extract ductwork
Toilet and washroom extract can carry moisture as well as dust, so the dust tends to cling. We clean them and note any damp or corrosion.
What happens on the day
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes from one overnight visit to a phased programme over several weeks. Most London sites cannot stop for the day, so work in Smithfield is typically done overnight, early in the morning or at weekends.
- First we plan when the work can happen, often out of hours.
- We open the ductwork through its access panels.
- Before pictures are taken and the ducts cleaned section by section.
- Grilles and diffusers are cleaned and refitted.
- After pictures are taken and the certificate and report issued.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Dig out any earlier paperwork for the system

What ventilation duct cleaning looks like in Smithfield
Food Standards Agency records list about 86 schools, colleges and universities, about 72 hospitals, care homes and childcare premises and about 211 hotels and B&Bs registered as food businesses across Smithfield and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Getting kit to a London plant room typically means lifts, stairs and an agreed loading slot. About 0.5 miles north-west of Smithfield is Finsbury Health Centre, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Finsbury Health Centre, about 0.5 miles north-west, is the nearest hospital to Smithfield, and healthcare sites of every size need their supply air kept clean. Wherever a school like Charterhouse Square School has ducted ventilation, a half-term visit keeps the work out of lesson time.

In-house cleaning or a specialist?
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Smithfield: your questions answered
Can the work in Smithfield be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you are closed and we’ll book within them.
Can parking be tricky for a job in Smithfield?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Night visits tend to make loading easier on London streets.
Do you clean grilles and diffusers?
Yes. Where they can be removed, they’re taken down, cleaned and refitted. Fixed ones are cleaned in place.
How does TR19 Air differ from TR19 Grease?
TR19® Air is the part of BESA’s TR19® that covers general supply and extract ventilation, rather than kitchen extract. It’s risk-based and led by inspection, while TR19® Grease covers kitchen extract systems.
Are you insured?
Yes. We carry full insurance, and we have been trading since 2009.
Do you provide a report?
Yes. You get a TR19® certificate and a report with before and after pictures. Keep them in the maintenance log.
Can you look after several sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
Do you look at the system first?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
What ventilation duct cleaning cannot fix
