Why it’s worth doing now in Penge
Grease left in a duct in Penge hardens over time. It bakes into a hard layer that takes far longer to remove, which makes each delayed clean a bigger one. London sites work long hours, and the longer a job is left, the bigger it gets.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before work begins.

About our ductwork cleaning in Penge
In doctor’s terms, the ductwork is the system’s arteries: find the blockages, clear them, then check the flow is right. Grease readings before and after give you the evidence, alongside before and after photos. We are often asked to deal with grease seeping out of the duct seams and an insurer asking for TR19 evidence, on attenuators, vertical risers and multi-storey ducts.
In a London area like Penge, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

When it’s something else
To be straight with you, there are a few things this work won’t fix:
- Ductwork that was poorly designed
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
- Fire dampers that don’t close (they need testing and remedials)
If in doubt, call 0345 646 2711 or drop us a line and we’ll say what we think.

Common questions in Penge
Do you work at weekends in Penge?
Yes, out-of-hours work is a big part of what we do. The work in Penge can fit around your hours. Your opening times are the first thing we ask for.
Who is the fire and rescue service for Penge?
Penge is in the area of London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
What’s the cleaning interval for extract ductwork?
The minimum depends on how long the kitchen cooks each day: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Measured grease sets the real interval.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
How long does it take to clean extract ducts?
A short duct can be cleaned in a few hours, while long ducts and tall risers can need more than one visit. We plan the work around your kitchen.
Which accreditations do you hold?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Is TR19 cleaning required by law?
No. TR19® itself isn’t law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Do we need to close while you work?
Not usually. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits to keep things running.
How the visit works
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes anything from a few hours to several visits, depending on the length of duct. Loading bays, visitor permits and roof access are the first things we ask about for a site in Penge.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Heavy deposits come out by hand, then each section is degreased.
- We close up, re-test, photograph and record anything out of reach.
How to prepare
- Clear the space around the work
- Tell us where we can park and unload
- Arrange a key holder or contact on site

Kitchen extracts in Penge
Food Standards Agency data counts about 269 restaurants, cafés and canteens and about 129 takeaways and sandwich shops within 1.5 miles or so of the middle of Penge. Behind every canopy among them is a run of ductwork that collects grease out of sight. Kitchens in Penge get their food hygiene inspections from Bromley council. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked. Most London extract cleaning happens at night, after the last service.
A hospital like St Christopher's Hospice, about 0.5 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you run a church or community hall kitchen, near Church of St John the Evangelist or elsewhere in Penge, its extract still collects grease from every lunch and event. If you run a café or takeaway near Penge West station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
For landlords and multi-site operators
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
Fixed quotes for ductwork cleaning in Penge
A fixed price needs a few facts first. We check:
- The times the site is available
- A single visit or a regular plan
- The scale of the work
- Where the site is and how we reach it
The cost depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.
What to send for a quote
We can often survey from pictures. Try to include:
- Any symptoms, from odd noises to smells or leaks
- The paperwork from the last visit, if you have it
- The site address and the type of premises
- Photos showing the whole system and its surroundings
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To get going, ring 0345 646 2711 or use the quote form.
Different parts, different methods
Bends and transitions
The join where the canopy meets the duct is a common hotspot. We reach it from the plenum side where possible.
Multi-storey and shared buildings
Long ducts in larger buildings can mean several visits. We agree a sequence that suits the building, out of hours where possible.
