In-house cleaning or a specialist?
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, alongside our reports.
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.
Ductwork cleaning for kitchens and businesses in Lissenden Gardens
Not every duct has enough access panels. Where a section cannot be reached, TR19 expects it to be recorded on the report, and new panels can be fitted to reach it in future. An honest report beats a guess. If you have fat dripping from the ductwork and years of grease along the duct floor, we can put it right, from attenuators, access panels and horizontal duct runs onwards.
London kitchens tend to trade late and open early, so extract cleaning in Lissenden Gardens is typically done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

How the job changes from site to site
Horizontal duct runs
A long flat run cannot be cleaned from one end. Any stretch out of reach is noted and can fit extra panels.
Access panels
Extra panels can be installed where there are gaps, so the next clean reaches more of the system. We will recommend where they should go.

Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Check readings when the menu changes
- Consider fitting panels where the report shows gaps
- File each certificate and photo report in the maintenance log
- Do not block access panels with shelving or stock
File the paperwork in the maintenance log. It’s the evidence an insurer or inspector may ask for, and the photos make the duct’s condition easy to see.
Run the extract the whole time the kitchen is cooking. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
Managing agents and facilities teams in Lissenden Gardens
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Leave it or put it right?
A partly blocked duct slows the airflow. The fan works harder, the kitchen gets hotter and smoke lingers at the canopy, and grease may start to leak from joints. In Lissenden Gardens, a planned overnight visit is much easier than closing unexpectedly.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.

Kitchen extracts in Lissenden Gardens
Food Standards Agency data counts about 684 restaurants, cafés and works canteens and about 324 sandwich bars and takeaways within roughly a mile and a half of the centre of Lissenden Gardens. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. Fire safety in Lissenden Gardens falls to London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Most London extract cleaning happens at night, after the last service.
If you run catering at a healthcare site, such as a hospital like Royal Northern Hospital about 1.2 miles east, the extract may need cleaning more often than a part-time kitchen. Where a hall near Highgate Road Chapel, or anywhere in Lissenden Gardens, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Lissenden Gardens: your questions answered
Can parking be tricky for a job in Lissenden Gardens?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
Do you clean school canteen extracts around Lissenden Gardens out of term?
Yes, and it’s the easiest time to do it. With about 69 schools and colleges on the FSA’s register within roughly a mile and a half of Lissenden Gardens, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
How do you keep the site clean during the work?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
How much notice do you need?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Is a quote from pictures possible?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
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. Every site has its own report.
Can you fit access panels in our ductwork?
Yes, we install duct access panels. We place them where they help most, and we’ll recommend where.
What if parts of the system can’t be reached?
Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
The process
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes from a few hours to more than one visit, depending on duct length and access. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Lissenden Gardens.
- First the duct route is traced and every access point noted.
- Set points along the runs are tested for grease.
- Access panels are opened and heavy deposits scraped out by hand.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- We test again, take pictures and note any part that couldn’t be reached.
How to prepare
- Let us know about parking and loading
- Mention any sign-in, permit or induction we need
- Have your last certificate or report to hand
