Kitchen duct cleaning in Canonbury

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 cleaning the whole system is how you keep it under control. If you’re dealing with heavy grease build-up inside the duct runs and proof of cleaning requested by an insurer, we can help, from canopies and hoods, horizontal duct runs and vertical risers onwards. Hood cleaning is where most enquiries from Canonbury start: a clean that goes past the canopy into the duct and fan, backed by a certificate.

Before we clean, we look at where the grease is: grease readings at set points tell us where the heaviest deposits are, and the same readings after the clean show the result.

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 Canonbury, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What happens if it’s left?

There’s no law that names TR19, but the Fire Safety Order 2005 still applies. 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. In a London building, a problem in a duct, damper or fan rarely stays in one unit.

What kitchen extract cleaning looks like in Canonbury

The FSA’s food hygiene register includes about 177 pubs, bars and clubs and about 18 hotels, B&Bs and guest houses in and around Canonbury, up to about a mile and a half out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Environmental health officers from Islington council inspect food businesses in Canonbury. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand. The fire and rescue service for Canonbury is London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

If you run catering at a historic house or estate in the area (Sutton House is about 1.7 miles east), event kitchens in older buildings often have awkward duct runs that need planning. For kitchens close to Canonbury station, where the day often starts early and ends late, the extract can be cleaned overnight.

Canonbury is about 2 miles north-east of St Pancras, in Greater London. Canonbury gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with photos.

Questions from Canonbury

Can you come to Canonbury after we close?

Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Canonbury needn’t be disturbed. Just call us on 0345 646 2711 or email us with your opening times and we’ll plan around them.

Does London parking affect a job in Canonbury?

A loading bay, a visitor permit or off-street space near the site in Canonbury makes the visit easier to plan. If the building has a loading slot system, we will book into it.

Do you clean the whole extract system or just the canopy?

A TR19 Grease clean covers the full extract route, not just the canopy. That means canopy, plenum, filters, ducts, risers, fan and discharge, reached through access panels where necessary.

Which sectors do you work in?

All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.

How much does kitchen extract cleaning cost?

Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll typically reply within one working day.

What should I send you?

Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply call us on 0345 646 2711, or email photos.

Do you cover Canonbury?

Yes. Our technicians work in Canonbury, within the South East and London area we cover.

Do you have a 24/7 line?

Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.

What the work involves, part by part

Ductwork and risers

Bends and changes of direction trap more grease than straight runs. Those are among the points where we take readings before and after, so the report shows the difference.

Canopy and plenum

Canopies vary from a single hood to long runs over several appliances, every section is cleaned and recorded in the photo report before and after.

Common problems we fix in Canonbury

What’s on the menu matters as much as how much is cooked. Frying, grilling and roasting send far more fat into the canopy than steaming or boiling, so two kitchens with the same hours can need very different intervals.

Common reasons sites call us are:

  • Rancid smells from grease in the duct
  • An extract that has never been cleaned to TR19
  • A smoky, hot kitchen with weak extraction
  • An inspection that picked up a dirty extract

Term dates shape school work: for a school like Rotherfield Primary School, an extract clean fits neatly into a half-term or summer break.

What your quote should include

  • When they can work, and whether that’s outside your opening hours
  • What insurance they carry
  • How VAT is shown on the quote
  • Which accreditations they hold, and whether you can check them

Questions to ask before booking

Keeping the system healthy

Results last longer with the right care. We suggest:

  • Wash or exchange the filters often
  • Don’t let the canopy gutters overflow
  • Book the next clean before the date on the report
  • Keep the extract on whenever the range is lit

After cleaning, we re-test the same points we measured at the start, giving you before and after readings alongside the pictures. Your TR19 certificate is then issued through the BESCA Vent Hygiene Elite portal.

Wipe the canopy down regularly and empty grease troughs or collection points. A daily wipe is not a deep clean, but it helps between visits.

Staff cleaning versus specialist work

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.

What happens on the day

Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a few hours for a small kitchen, longer for a large system. In a London area like Canonbury, parking, loading and building access are planned before the day of the work.

  1. We survey the system first, from your pictures and details or on a site visit.
  2. Grease readings are taken at set points and you get a fixed quote.
  3. On the day, cooking equipment is switched off and left to cool, and everything nearby is sheeted.
  4. Canopy, plenum, filters, duct runs, risers, fan and discharge are all cleaned to TR19® Grease.
  5. We test again, photograph the result and issue your TR19 certificate and photo report.

How to prepare

  • Make sure equipment near the work can be switched off and left to cool
  • Arrange a key holder or contact on site
  • Tell us where we can park and unload

How to get a quote

There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.
