The process

Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes anything from a few hours to several visits, depending on the length of duct. Night and weekend working is normal for us in London, and a site in Hendon is no exception.

  1. The duct route is surveyed and every access point found.
  2. Grease thickness is measured at set points.
  3. Once the kitchen has closed, we protect the area and open the panels.
  4. Heavy deposits come out by hand, then each section is degreased.
  5. Panels are closed, readings and photos repeated, and unreachable sections recorded.

Before we arrive

  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Clear loose items from the work area
  • Have your last certificate or report to hand

About our ductwork cleaning in Hendon

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 that is where a kitchen fire can travel. We clean it from the inside, through access panels, to BESA TR19® Grease. If you have hardened, baked-on grease in long horizontal runs and stale grease odours from the duct, we can help.

In London, few kitchens can spare a day to close, so extract cleaning in Hendon is usually done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.

For insurers and inspectors, the record counts. 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.

What the work involves, part by part

Horizontal duct runs

Horizontal runs carry the extract along ceilings and through voids. Grease drops out of the slowing air along them, so each section is cleaned through its access panels.

Multi-storey and shared buildings

In a shared building, the duct links the kitchen to other spaces, so the responsible person has more reason to keep it clean. Your certificate and report give building managers the record they need.

Common problems we fix in Hendon

Risers carry the extract up through the building. Grease clings to the walls and can run down to the base as liquid grease runs down. Panels along the riser make proper cleaning possible.

These are the problems we see most often:

  • A grease test showing the duct is overdue
  • Sections of duct with no access panels
  • Thick deposits at the bottom of a vertical duct
  • Smells of old cooking grease from the ductwork

If you cook for passing trade around Hendon station, the extract can be cleaned between your last and first customer.

Questions to ask before booking

  • How they set the interval to the next visit
  • What happens if part of the system can’t be accessed
  • Whether the work can be done while the site is closed
  • Exactly which parts of the system are covered

What affects the quote in Hendon

Every site gets its own quote. These are the things that affect it:

  • Site requirements such as sign-in and permits
  • One-off work versus a regular cycle
  • Whether several sites go on one quote
  • How easy every part is to reach

What you pay depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.

What we need to know

Many jobs can be priced from pictures and some basics. Useful things to send:

  • The roof, plant room or outside wall the system runs to
  • Any previous report or certificate
  • Detail shots of panels, filters and grilles
  • When the site is open and when it’s quiet

To get a fixed quote, give us a ring on 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You will typically have a quote within one working day.

What happens if it’s left?

There’s no law that names TR19. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. A busy site in Hendon builds up dirt and wear quickly, so putting it off makes the eventual job larger.

Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before we start.

Hendon kitchens: local notes

Food Standards Agency records include about 20 pubs, bars and clubs and about 8 hotels and guest houses in and around Hendon, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. In London, kitchens are normally cleaned overnight, when the kitchen is closed and loading is easier. In Hendon, food businesses are inspected by environmental health officers from Barnet council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.

Volunteers running a hall kitchen near Christ Church Hendon, or anywhere in Hendon, may not know when the extract was last cleaned, and a grease test settles it. Term dates shape school work: for a school like Hendon School, an extract clean fits neatly into a half-term or summer break.

Hendon is about 3 miles north-west of Hampstead, in Greater London. Across the NW4 area, we can carry out ductwork cleaning at your premises. Across Greater London, we cover 764 places, Hendon among them. Our London page covers sites nearby (8 miles or so).

Landlords, agents and facilities managers

Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.

Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.

Between visits

Think of this as the after-treatment advice, short and simple:

  • File each certificate and photo report in the maintenance log
  • Keep the fan on while anything is cooking
  • Have the grease measured if cooking hours go up
  • Keep access panels clear of stored items

After the clean, the same points are tested again, giving you before and after readings. Before and after pictures sit next to the numbers.

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.

Your questions about ductwork cleaning in Hendon

Do you work overnight in Hendon?

Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.

Which fire and rescue service is responsible for Hendon?

Fire safety enforcement in Hendon is handled by London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

What if part of the duct can’t be reached?

Without a way in, a section can’t be cleaned properly. We record those sections on the report and can fit access panels.

How do you protect the area?

We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.

Will I get a report after the ducts are cleaned?

Every clean comes with a photo report, and a full TR19 clean also comes with a certificate issued through the BESCA Vent Hygiene Elite portal. Keep both in the maintenance log.

How do you clean inside the ductwork?

Each section is cleaned through its own panel. Grease is scraped out first, then degreased, with readings taken before and after.

Is Hendon in your area?

Yes. Our technicians work in Hendon, as part of our area across London and the South East.

Which accreditations do you hold?

We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
