Ductwork cleaning for kitchens and businesses in Downham
Nobody sees duct grease building, so nobody notices it until something goes wrong. A flare-up drawn up from the range can light it, and fire can then run along the ductwork to other parts of the building. Removing it is the whole point. The work covers vertical risers, horizontal duct runs and multi-storey ducts, and the jobs we see most are heavy grease at the base of a riser and a grease test showing the duct is overdue.
In a London area like Downham, 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.
Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What the work involves, part by part
Multi-storey and shared buildings
A duct that climbs several floors may be cleaned over more than one visit. Visits are planned around the building’s hours, out of hours where possible.
Vertical risers
Risers carry the extract up through the building to the roof. Grease collects on the walls and at the foot of the riser, so the base is one of our test points.
Do you need ductwork cleaning in Downham?
Risers carry the extract up through the building. Grease clings to the walls and can run down to the base as liquid grease runs down. Access along its height is needed to clean it properly.
If you notice any of these, it’s worth a diagnosis:
- Hardened, baked-on grease in long horizontal runs
- Fat dripping from the ductwork
- Ductwork that has never been cleaned
- High readings at a recent grease test
Where a hall near St Barnabas, or anywhere in Downham, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

The process
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Expect the work in Downham to happen after your last customer leaves, not during trading.
- First we diagnose: the route, the access and the grease levels.
- You get a fixed price before work starts.
- We clean section by section, working from panel to panel.
- Bends, risers and the base of each riser get extra attention.
- The duct is signed off with readings, photos and a next clean date.
Before we arrive
- Move anything stored near the system
- Find the previous report, if there is one
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Ductwork cleaning around Downham
Food Standards Agency records list about 152 cafés, restaurants and staff canteens and about 80 takeaways and sandwich shops in and around Downham, up to about a mile and a half out. Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. In Downham, food businesses are inspected by environmental health officers from Lewisham council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.
Healthcare kitchens, like those at hospitals such as Bromley Hospital (about 2.1 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands. For kitchens close to Grove Park station, where the day often starts early and ends late, the extract can be cleaned overnight.
Downham is about 2 miles north of Bromley, in Greater London. Across the BR1 area, we can carry out ductwork cleaning at your premises. Our area takes in 764 places across Greater London, from busy centres to quieter spots. London is in our area too, around 7 miles away.

Local landmarks in Downham
Locally, jobs take us to businesses close to Holy Trinity College Bromley, Downham Fields and Bonus Pastor Catholic College. The closest station to Downham is Grove Park station, about 0.8 miles north-east of the centre. Other landmarks nearby include The Glades (1.6 miles south) and Greenwich Castle (3.6 miles north). Open spaces near Downham include Summer Hill and Downham Woodland Walk.
What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Your questions about ductwork cleaning in Downham
Can parking be tricky for a job in Downham?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, usually makes it simpler.
Do you do school kitchen extract cleaning in Downham in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 22 schools, colleges and universities with registered kitchens within about a mile and a half of Downham. Just call 0345 646 2711 or email us with your term dates and we will plan around them.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
What’s the cleaning interval for extract ductwork?
BESA guidance sets minimum intervals by daily cooking hours: 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.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Call us any time and explain what’s happened.
Do I get a certificate for ductwork cleaning?
A full system clean comes with a TR19 certificate and a photo report. The report shows readings, pictures and any sections we couldn’t reach.
Keeping the system healthy
Results last longer with the right care. We suggest:
- Keep your cleaning records together
- Do not block access panels with shelving or stock
- Ask for a grease thickness test if the kitchen gets busier
- Diarise the next duct clean
File the paperwork in the maintenance log. It’s the evidence an insurer or inspector may ask for, and the pictures make the duct’s condition easy to see.
Keep to the cleaning interval on the report. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
What a clean will not put right
We will always give you a straight diagnosis, so here’s what this work cannot put right:
- Ductwork that was poorly designed
- Parts of the duct with no way in
- Fire dampers that do not close (they need testing and remedials)
If in doubt, call 0345 646 2711 or send us an email and we’ll say what we think.
Parts of the system we cover

Why act early in Downham
TR19® isn’t law, but the duty to manage fire risk is. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, including the grease inside the extract ductwork. Every month a London system goes without attention adds to what has to be done later.
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before any work starts.
