Grease, kitchens and Longlands
Food Standards Agency records include about 30 pubs and bars across Longlands and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. London jobs normally start after the last service, with loading and roof access agreed with the building first. London Fire Brigade covers Longlands. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Volunteers running a hall kitchen near Christ Church, or anywhere in Longlands, may not know when the extract was last cleaned, and a grease test settles it. If you cook for passing trade around New Eltham station, the extract can be cleaned between your last and first customer.
Longlands is about 1 mile west of Sidcup, in Greater London. Every kind of commercial site in Longlands, we can take on ductwork cleaning. We can work out of hours so the site keeps running. Across Greater London, we cover 764 places, and Longlands is one of them. We also work in London, around 9 miles away.
We cover every part of DA15, DA14 and SE9 for ductwork cleaning and the streets around it. You’ll find streets such as Main Road, Alder Road and Sidcup Road, all of which we cover for ductwork cleaning. Being close to the A211, Longlands is simple for us to get to at any hour. Nearby, we also carry out ductwork cleaning in Foxbury (1 mile south), New Eltham (1 mile north-west), Chislehurst (1 mile south-west), Coldharbour (1 mile west) and Blackfen (1 mile north). We also work in nearby towns such as London (9 miles north-west), City of Westminster (12 miles north-west), Marylebone (12 miles north-west), Kensington (13 miles west), St Pancras (11 miles north-west) and Shoreditch (10 miles north-west).

Ductwork cleaning in Longlands, done properly
Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Every horizontal run and vertical riser collects grease along the way and a fire in the duct can spread through the building. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. The work covers attenuators, multi-storey ducts and vertical risers, and people most often call us about grease pooling at the foot of the riser and a grease test showing the duct is overdue.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In Longlands, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Your questions about ductwork cleaning in Longlands
Do you clean school canteen extracts around Longlands out of term?
Yes, holiday work suits schools best. There are about 29 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Longlands. Send us your term dates when you give us a ring on 0345 646 2711 or drop us a line, and we’ll fit the work in.
Who is the fire and rescue service for Longlands?
London Fire Brigade is the fire and rescue service for Longlands. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
How do you keep the site clean during the work?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
How much does ductwork cleaning cost in Longlands?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we will usually reply within one working day.
Will the duct clean disrupt the kitchen?
Out of hours, at a time that suits the kitchen. Long ducts can be split across visits, with the kitchen ready to cook each morning.
How do you know if the ductwork needs cleaning?
Signs include grease dripping from joints, smells and a fan working harder, but the only sure way is to measure. A WFTT or DTT reading gives a clear answer.
Signs you need ductwork cleaning in Longlands
Air cools as it moves away from the canopy. As it cools, the grease it carries condenses onto the duct walls, so duct runs keep collecting grease long after the canopy.
What we’re most often called out for:
- Gaps where access panels were never fitted
- Ductwork that has never been cleaned
- Smells of old cooking grease from the ductwork
- An insurer asking for TR19 evidence
If you look after a school kitchen, at a school such as Longlands Primary School or anywhere near Longlands, the holidays are the usual time for a TR19® clean.

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. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. On site, it takes anything from a few hours to several visits, depending on the length of duct. Expect the work in Longlands to happen after your last customer leaves, not during trading.
- Diagnosis: a survey of the duct’s route, size and access.
- You get a fixed price before work starts.
- Each section is cleaned in turn through its access 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.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Arrange a key holder or contact on site
- Clear the space around the work
Ask for a quote
Getting a quote doesn’t take long. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Advice
Aftercare tips
A little care between visits keeps the system in better shape. We recommend:
- Book the next clean before the recommended date
- Keep access panels clear of stored items
- Have the grease measured if cooking hours go up
- Flag drips from the duct right away
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It records the date, the location and the technician.
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 staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.

Fixed quotes for ductwork cleaning in Longlands
We quote each job individually. This is what makes a difference:
- How many systems or sites are involved
- Where the site is and how we reach it
- Whether we need access equipment or extra panels
- Whether it’s a one-off visit or part of a schedule
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
How the job changes from site to site
Vertical risers
In taller buildings, a riser may pass through several floors and fire compartments, where fire dampers may be fitted. We test those as a separate job.
Multi-storey and shared buildings
Long ducts in larger buildings can mean several visits. Visits are planned around the building’s hours, out of hours where possible.
When something else is needed
To be straight with you, there are a few things this work will not fix:
- A duct that is too small or badly routed for the kitchen (a design issue)
- A worn-out fan that needs replacing
- Parts of the duct with no way in
Not sure which it is? You can give us a ring on 0345 646 2711 or send us an email and we will tell you honestly before booking.
