About our kitchen extract cleaning in Sydenham
Every time food is cooked, warm vapour carries fat up into the extract. As it cools, it clings to the inside of the ductwork and keeps building. That film is fuel, and a proper clean removes it before it becomes a fire risk. If you have rancid smells from grease in the duct and cleaning needed before an insurance renewal or survey, we can put it right, from horizontal duct runs, discharge points and extract fans onwards. When a restaurant in Sydenham asks for duct cleaning, it’s nearly always the kitchen extract they mean, and that is our main job: the whole run from hood to roof, cleaned to TR19® Grease.
What can be cleaned depends on what can be reached. Where a duct run has no panels, we say so on the report and can fit new ones.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. In Sydenham, 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 pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What affects the cost of kitchen extract cleaning
There’s no set price list, because no two systems are the same. The quote depends on:
- The condition we find in the survey
- How big the system is
- Working hours and out-of-hours timing
- The number of sites or systems
What you pay depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- The times we could work without disrupting the site
- Any access panels or hatches you can see

How the job changes from site to site
Extract fan and discharge
Some systems have attenuators to cut noise, and they hold grease. Where they can be cleaned, they are, and the report notes anything that cannot.
Canopy and plenum
Canopies vary from a single hood to long runs over several appliances, each section is cleaned and photographed before and after.
Why act early in Sydenham
A clogged extract doesn’t only raise the fire risk. Filters block, airflow drops and the kitchen gets hotter and smokier, while the fan works harder to move less air. Smells, dripping grease and condensation often follow. Planning ahead in Sydenham lets you pick a quiet night rather than lose a busy one.
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or use the quote form, and we’ll explain what it covers.

Questions from Sydenham
Who is the fire and rescue service for Sydenham?
It’s London Fire Brigade, which covers Sydenham. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Do you do school kitchen extract cleaning in Sydenham in the summer holidays?
Yes, holiday work suits schools best. With about 40 schools and colleges on the FSA’s register within roughly a mile and a half of Sydenham, it pays to plan holiday dates ahead. You can ring 0345 646 2711 or email us with the dates the site is empty.
How often should a kitchen extract be cleaned?
That comes down mainly to daily cooking hours. Heavy use of 12 to 16 hours a day calls for a clean at least every 3 months under BESA guidance, and lighter use less often. Your report gives a recommended next clean date.
What about areas you can’t get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Can you quote from photos?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Each site gets its own report and pictures.
Do I have to clean my extract to TR19 by law?
Strictly, the legal duty comes from the Regulatory Reform (Fire Safety) Order 2005, not from TR19. In practice, TR19 is how kitchens show they’re managing grease, and many insurers ask for proof of it.
Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
The process
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes as long as the system needs, from a few hours to several planned visits. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Sydenham.
- We start with a survey, so we know every part of the system before we quote.
- Grease readings are taken at set points and you get a fixed quote.
- Once the kitchen has closed and the equipment has cooled, we sheet and protect the area.
- Canopy, plenum, filters, duct runs, risers, fan and discharge are all cleaned to TR19® Grease.
- Readings and pictures are taken again, and you receive a TR19 certificate and photo report.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Mention any locked doors, roof access or ceiling voids
- Let us know about parking and loading
How to get a quote
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 work begins.

Grease, kitchens and Sydenham
The FSA’s food hygiene register includes about 54 pubs, bars and clubs and about 5 hotels and B&Bs in Sydenham and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. London jobs typically start after the last service, with loading and roof access agreed with the building first. Sydenham is covered by London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
School kitchens, at schools like Kirkdale School for example, are usually cleaned in the holidays so no lunches are lost. A kitchen near Sydenham station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
Sydenham is about 3 miles south-east of East Dulwich, in Greater London. Wherever you are in the SE26 postcode area, we can take on kitchen extract cleaning. 764 places in Greater London are on our list, from busy centres to quieter spots.
All of SE26, SE20 and SE23 is within our area for kitchen extract cleaning, from the main roads to the quietest streets. If you need kitchen extract cleaning at premises on Byne Road, Lucas Road and Cator Road or anywhere close by, our technicians can take on the work. Nearby, we also carry out kitchen extract cleaning in Penge (1 mile south), Crystal Palace (1 mile south-west), Sydenham Hill (1 mile north-west), Perry Vale (1 mile north-east) and Anerley (1 mile south-west). Further out, we also cover London (5 miles north), City of Westminster (7 miles north-west), Marylebone (8 miles north-west), Kensington (8 miles north-west), St Pancras (7 miles north) and Shoreditch (7 miles north).
Around Sydenham
Locally, jobs take us to businesses close to St Bartholomews's Church of England Primary School, Sydenham High School and Mayow Park. Sydenham has its own railway station: Sydenham station. A little further out are Greenwich Castle (4.3 miles north-east) and Crystal Palace Museum (1 mile west). Green spaces nearby include Dacres Wood and Knight's Hill.
Common problems we fix in Sydenham
What’s on the menu matters as much as how much is cooked. Fryers, grills and open flames throw much more fat into the extract than gentler cooking, so two kitchens with the same hours can need very different intervals.
Common reasons sites call us include:
- Ductwork thick with old, hardened grease
- Grease dripping from the canopy or filters
- Stale cooking odours from the system
- Poor airflow at the canopy
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St Christopher's Hospice is the nearest hospital to Sydenham, about within half a mile south-west.
