Commercial kitchen extraction cleaning in Blackheath
A closed kitchen isn’t earning, so the timing of a clean matters. Cleans are booked for evenings, overnight or weekends, or between services where the kitchen has a gap. With the equipment off and cool and the area sheeted, we clean and hand the kitchen back ready for the next service. The work covers extract fans, canopies and hoods and plenums and filters, and people most often call us about years of baked-on grease in the ducts and a new tenancy or takeover with no cleaning history. Most calls from Blackheath come after an insurer, an EHO or a fire officer asks to see the last TR19 certificate. We handle the clean and the paperwork in one visit.
Kitchens that fry and grill hardest need the most frequent cleans, so we look at the menu as well as the opening hours when we suggest the next date.
London kitchens tend to trade late and open early, so extract cleaning in Blackheath is normally done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Blackheath questions
Which fire service covers Blackheath?
It’s London Fire Brigade, which covers Blackheath. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you clean school canteen extracts around Blackheath out of term?
Yes. The holidays are the usual time for school work. Around Blackheath, the Food Standards Agency lists about 47 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
How long does it take to clean a kitchen extract system?
Allow as long as the system needs, from a few hours to several planned visits. The survey tells us how long your system will need.
What does kitchen extract cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before any work starts.
Is TR19 a legal requirement?
Strictly, the legal duty comes from the Regulatory Reform (Fire Safety) Order 2005, not from TR19. TR19 is the industry benchmark for meeting that duty in a kitchen extract, and many insurers ask for proof of it.
What do you need from me for a quote?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply ring 0345 646 2711, or send details by email.
How often does a kitchen extract system need cleaning?
BESA guidance gives minimum intervals of 3, 6 or 12 months, depending on daily cooking hours. Heavy frying and grilling can mean shorter intervals, which grease thickness testing will show.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
How the job changes from site to site
Canopy and plenum
The canopy catches the vapour, and the plenum behind the filters is where it first condenses. Both are scraped and degreased inside and out, with the filter housing cleaned too.
Grease filters
Between TR19 cleans, filters still need regular cleaning, and a filter exchange service can take that off your hands. Keeping them clean helps the rest of the system stay cleaner.
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes a few hours for a small kitchen, longer for a large system. A name and number for whoever controls access to the building in Blackheath saves time on the night.
- We survey the system first, from your pictures and details or on a site visit.
- We measure the grease at set points along the system, then give you a fixed price.
- 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.
- We test again, photograph the result and issue your TR19 certificate and photo report.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Find the previous report, if there is one
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.
Advice
Why it’s worth doing now in Blackheath
TR19® is not law, but the Regulatory Reform (Fire Safety) Order 2005 is. The responsible person must assess and reduce fire risk, which in a kitchen includes the grease in the extract. TR19 is the benchmark insurers, fire officers and EHOs look to. For a site in Blackheath, fitting the work in overnight now is far easier than closing at short notice later.
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711, or email photos, and we will explain what it covers.

What kitchen extract cleaning looks like in Blackheath
Food Standards Agency data counts about 328 cafés, restaurants and staff canteens and about 146 takeaways within roughly a mile and a half of the centre of Blackheath. Any of them cooking under a canopy is sending grease into its ductwork every service. Food hygiene inspections in Blackheath are the job of Lewisham council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. Blackheath is covered by London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
A kitchen near Blackheath station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. A hospital like Greenwich District Hospital, about 1.1 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Blackheath is about 1 mile south-east of Greenwich, in Greater London. Blackheath gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with photos. Blackheath is one of 764 places in Greater London we cover for kitchen extract cleaning.

Near you in Blackheath
Typical jobs here are in premises near The Princess Of Wales Pub, Blackheath Proprietary School and Manor House Gardens and the streets around them. Blackheath has its own railway station: Blackheath station. A little further out are Lewisham Shopping Centre (1.1 miles south-west) and Royal Observatory (0.7 miles north-west). The countryside around Blackheath includes Tower Hill and Birdbrook Road Nature Reserve.
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Empty any grease troughs or cups on the canopy
- Diarise the next clean as soon as you get the certificate
- Wash or exchange the filters often
- Keep the cleaning records where you can find them
The report gives a recommended date for the next clean, based on your cooking hours and the grease we measured. We can put the system on a 3, 6 or 12-monthly plan, so the date isn’t missed.
Report drips, smells or a noisy fan early. Drips, odours and fan noise often mean grease is building, and a grease thickness test can confirm it.
What kitchen extract cleaning can’t fix
It’s worth knowing the limits before booking:
- A duct that’s holed or coming apart
- Blocked drains from a neglected grease trap (a separate service)
- Faulty fire dampers in the duct
Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we’ll tell you honestly.

Common problems we fix in Blackheath
Grease in the extract matters because it burns. Flames from a pan or grill can be pulled into the canopy by the fan, and once grease in the duct catches, fire can spread through the building’s ductwork. For a kitchen in Blackheath, keeping that fuel under control is part of the fire risk assessment.
Look out for these warning signs:
- Rancid smells from grease in the duct
- Extraction mentioned at an environmental health visit
- A system with no record of a TR19 clean
- Poor airflow at the canopy
Where a hall near Church of All Saints, or anywhere in Blackheath, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Questions to ask before booking
- Whether they recommend a next date
- Which accreditations they hold, and whether you can check them
- Whether the quote is based on a survey or pictures
- Proof of insurance
What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
