How the visit works
A visit follows the same order every time: protect the area, isolate whatever needs isolating, do the work, clear away and leave you the report. On site, the work takes from a few hours to more than one visit, depending on duct length and access. Most London sites cannot stop for the day, so work in St Luke's is normally done overnight, early in the morning or at weekends.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Heavy deposits come out by hand, then each section is degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Before we arrive
- Name a contact who can let us in at the agreed time
- Agree a time when the area can be out of use
- Tell us about site rules, permits or sign-in

Advice
Ductwork cleaning in St Luke's, done properly
Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it, and that’s where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. Common call-outs are for grease leaking from duct joints and smells of old cooking grease from the ductwork, across multi-storey ducts, vertical risers and attenuators.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. In St Luke's, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

For landlords and multi-site operators
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Looking after it afterwards
Results last longer with the right care. We suggest:
- Diarise the next duct clean
- Leave a way through to the access panels
- Check readings when the menu changes
- Never cook with a filter missing
The report gives a recommended next clean date, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Book the next duct clean before the date passes. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
Why deal with it now?
BESA guidance says grease shouldn’t exceed a mean of 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean right away. Putting off the clean only pushes readings higher. In St Luke's, as across London, ductwork often passes through shared risers and other people’s space.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, call us on 0345 646 2711 or email us for straight advice and a fixed quote.

What else we do in St Luke's
What ductwork cleaning looks like in St Luke's
Food Standards Agency records include about 516 pubs, bars and clubs and about 126 hotels and guest houses within 1.5 miles or so of the middle of St Luke's. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kitchens in St Luke's get their food hygiene inspections from the City of London Corporation. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
Term dates shape school work: for a school like St Luke's CofE Primary School, an extract clean fits neatly into a half-term or summer break. A kitchen near Old Street station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Do we lose a day’s trading?

By covering it before any work starts. The work is kept contained and clean down when we finish.
Different parts, different methods
Access panels
After cleaning, every panel is closed and sealed, so grease and air stay inside the duct. We will tell you if any panel needs replacing.
Attenuators and discharge
The last section of duct before the discharge is often the coolest, which can mean heavier deposits. We include it in the clean and the readings.
Signs you need ductwork cleaning in St Luke's
Grease in a duct running from a kitchen in St Luke's is as much a fire risk as in any building. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
What we are most often called out for:
- Years of grease along the duct floor
- A duct clean needed for an insurer
- Stale grease odours from the duct
- A duct nobody has opened in years
Healthcare kitchens, like those at hospitals such as St Luke's Hospital for Lunatics (about less than half a mile east), often cook for long hours, which puts them in BESA’s heavier-use bands.
