Extract fan cleaning across Derry Downs

How we handle extract fan cleaning in Derry Downs

Any fan serving a kitchen in Derry Downs is cleaned the same careful way as anywhere else: isolated first, then opened, scraped and degreased. The result is photographed for your records. If you have grease escaping from the fan outlet and a motor area thick with grease, we can help, from in-line fans, axial fans and centrifugal fans onwards.

Kitchens in Derry Downs, like many across London, can share a building with flats or offices, with the duct running up through shared risers. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.

Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Questions from Derry Downs

Who carries out food hygiene inspections in Derry Downs?

Food hygiene inspections in Derry Downs are carried out by Bromley council. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.

How do you handle parking and loading in Derry Downs?

Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, typically makes it simpler.

How do you protect the area?

We cover floors and nearby surfaces with sheeting before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.

What paperwork do I get after a fan clean?

Photos, notes on condition and a recommended next date. Keep it with your maintenance log.

How long will it take to clean the fan?

One easily reached fan is quick, but hard-to-reach fans take more time. We plan it out of hours.

Is TR19 a legal requirement?

No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.

Do you cover Derry Downs?

Yes. We work in Derry Downs and across Greater London, as part of our work across South East England and London. For a fixed quote, give us a ring on 0345 646 2711 or send us an email.

Do you offer emergency callouts?

Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.

What extract fan cleaning cannot fix

We’ll always give you a straight diagnosis, so here’s what extract fan cleaning will not do:

  • A fan that won’t start
  • A cracked or broken impeller (it needs replacing)
  • A fan that is too small for the system (a design question)

If in doubt, call 0345 646 2711, or send details by email and we’ll say what we think before booking.

  • How easy every part is to reach
  • Working hours and out-of-hours timing
  • What state the system is in

Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

Helping us quote

To help us quote quickly, please include:

  • Any symptoms, from odd noises to smells or leaks
  • The roof, plant room or outside wall the system runs to

Quotes are quick. Call or email with a few details and you’ll usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Signs you need extract fan cleaning in Derry Downs

Grease condenses as the air cools, and a fan out on a roof or wall often sits where the air is coolest. So grease often settles heavily there.

Look out for these warning signs:

  • A motor area thick with grease
  • An extract fan with no cleaning record
  • Weak extraction at the canopy
  • A fan that hums, whines or rumbles

If you look after a school kitchen, at a school such as St Philomena's Primary School or anywhere near Derry Downs, the holidays are the usual time for a TR19® clean.

Questions to ask before booking

The process

Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes a couple of hours per fan, depending on its size and the build-up. Loading bays, visitor permits and roof access are the first things we ask about for a site in Derry Downs.

  1. First we check the fan’s condition and how it sounds.
  2. With the fan isolated, the housing is opened.
  3. Each blade is cleaned so the impeller runs evenly.
  4. Housing, outlet and the area around the motor are cleaned.
  5. We run the fan and note its condition in the photo report.

Getting ready for the visit

  • Move anything stored near the system
  • Name a contact who can let us in at the agreed time
  • Allow time for equipment near the work to be turned off and cool down

How the job changes from site to site

Roof-mounted fans

Many kitchen extracts end at a fan on the roof. They’re cleaned where safe access allows, with any limits noted.

Wall fans

Smaller kitchens may extract through a fan on an outside wall. It’s isolated, opened and cleaned inside and out.

Keeping the system healthy

A little care between visits keeps the system in better shape. We recommend:

  • Notice when the fan starts to sound different
  • File the fan’s report with your other records
  • Keep access to the fan clear
  • Watch for grease marks around the outlet

A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. If only the fan is cleaned, the photo report says so.

Fewer grease particles reaching the fan means less build-up. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.
