Extract fan cleaning near Greenwich

What the work involves, part by part

Fan housings and motors

Inside the casing, grease is thrown onto the walls. We clean it along with the blades.

Inline duct fans

An inline fan can be easy to forget because it’s out of sight. The survey makes sure it’s part of the clean.

Extract fan cleaning in Greenwich, done properly

A fan never collects grease in a neat, even layer. Uneven build-up unbalances the impeller, which brings vibration, noise and extra wear on the bearings and motor. A thorough clean removes the cause. If you are dealing with a heavily greased fan housing and grease stains around the discharge, we can put it right.

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

Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

The process

When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes a few hours where there are several fans or heavy deposits. If your building in Greenwich has sign-in rules, permits or key holders, mention them when you book.

  1. The fan is found and its type, access and isolation checked.
  2. It’s isolated so it cannot run while we work.
  3. Grease is scraped off the impeller blades and casing.
  4. Blades, housing and surrounds are degreased with care around the electrics.
  5. It’s closed up, run, checked and photographed for the report.

How to prepare

  • Tell us about site rules, permits or sign-in
  • Let us know when the site is closed or quiet
  • Let us know about parking and loading

Greenwich: your questions answered

How do you handle parking and loading in Greenwich?

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, normally makes it simpler.

Who enforces fire safety at workplaces in Greenwich?

That’s London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Who is responsible for fire safety on the premises?

It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.

Do you repair extract fans as well as clean them?

A fan that needs repair is noted on the report, with what we found. We offer extract fan repair and replacement, and if it fails outright, our 24/7 emergency line is there.

Can the fan be cleaned between full cleans?

Yes, we can clean just the fan. It’s useful when a fan is noisy or greasy between full cleans, but it does not replace a full TR19 clean.

Can you set up regular visits?

Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.

What happens if you can’t reach some of it?

We record them on the report, with pictures where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.

Do you have insurance?

Yes. We carry full insurance, and we’ve been trading since 2009.

Why act early in Greenwich

For a kitchen in Greenwich, a noisy, greasy fan is often the first sign the whole system is overdue. Grease on the fan means grease in the duct before it, so it’s worth checking the whole system. In Greenwich, as across London, ductwork often passes through shared risers and other people’s space.

Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, phone us on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

Why us?

  • A written report with pictures after each visit
  • Accredited under CHAS and SafeContractor, with ISO 9001
  • Trading since 2009
  • Full insurance on every job

What extract fan cleaning looks like in Greenwich

The FSA’s food hygiene register includes about 76 bars, pubs and nightclubs and about 11 hotels, B&Bs and guest houses in and around Greenwich, up to about a mile and a half out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. London Fire Brigade covers Greenwich. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. London jobs typically start after the last service, with loading and roof access agreed with the building first.

Where a hall near St Mary's Church, or anywhere in Greenwich, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Term dates shape school work: for a school like Meridian Primary School, an extract clean fits neatly into a half-term or summer break.

Landlords, agents and facilities managers

We also work for facilities teams across offices, schools and healthcare in Greenwich and across Greater London. Larger estates can be phased building by building around the people who use them.

Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.

Common problems we fix in Greenwich

A fan on a roof or hidden in a ceiling void is easy to forget. A fan that has never been cleaned can be heavily coated, and the report will show it.

Clients typically contact us when they notice something like this:

  • Grease stains around the discharge
  • A smell of hot grease from the extract
  • A motor area thick with grease
  • Vibration from an unbalanced impeller

For kitchens close to Maze Hill station, where the day often starts early and ends late, the extract can be cleaned overnight.

What your quote should include

  • Exactly which parts of the system are covered
  • When they can work, and whether that’s outside your opening hours
  • Whether VAT is included
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

Our hiring checklist

What your team can do, and what needs us

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.

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.

Looking after it afterwards

To keep the system working properly between visits:

  • Don’t store items in front of the fan’s access point
  • Tell us if the extract feels weaker
  • Make sure the fan is included each time
  • Report rattles or humming early

The area around the fan is left clean, with waste grease removed. On a roof or outside wall, we leave the surrounding area tidy.

Make sure the fan is reachable. Clear access means it’s never left out of a clean, whether it’s on a roof, in a ceiling or on a wall.
