How we handle extract fan repair in Green Street Green
The extract fan is what pulls smoke, heat and steam out of the kitchen. When it starts to rattle, hum or slow down, the cooking area soon fills with heat and fumes. Our engineers track down the fault and fix it, by repairing the fan or replacing it. Typical jobs include an extract fan that rattles or knocks and a fan running too slowly to clear the kitchen, on fan housings, belts and pulleys and kitchen extract fans.
For a London kitchen, a failed extract fan typically means the cooking stops. Fans in Green Street Green are often on a roof or in a basement at the end of a long duct run, so access is the first thing we ask about.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

How the visit works
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.

- We ask what the fan is doing, from noise and vibration to a full stop.
- Power to the fan is isolated before we open the housing.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- You get our diagnosis and a fixed quote to repair or replace.

Advice
What extract fan repair looks like in Green Street Green
Look up Green Street Green on the FSA’s food hygiene register and you will find about 35 restaurants, cafés and works canteens and about 17 sandwich bars and takeaways in and around Green Street Green, up to about a mile and a half out. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. In Green Street Green, food businesses are inspected by environmental health officers from Bromley council. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. So a failed fan is worth fixing before the next service, not the next month. A failed fan in a London kitchen normally means a closed kitchen, so access details help us plan the repair.
If you run a school kitchen, at a school such as Green Street Green Primary School or nearby, a fan that is getting noisy is best repaired in the holidays before it fails in term. If you look after a church or hall kitchen near St Mary's Church, or anywhere in Green Street Green, test the extract fan before a big event rather than on the day. If you run a café or takeaway near Chelsfield station, a failed fan in the middle of service is exactly what our 24/7 emergency line is for.

For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.

Part by part
Roof and wall-mounted fans
An external fan’s rattle can be heard outside. It’s often down to loose mounts or worn bearings.
Fan controls
Where the fault is in the building’s electrical supply, an electrician is needed. We’ll tell you if that’s what we find and explain what we found.
Keeping the system healthy
Once we have finished, these simple steps help:
- Don’t cook with gaps in the filter bank
- Keep the grease filters clean and fitted
- Keep the fan on a planned cleaning cycle
- Report new noises from the fan early
We run the fan and check it’s steady before we go. We explain the fault and the fix, and anything else we noticed is pointed out.
A slipping belt or a loose mount is a small job. Left for months, they can damage the motor or bearings so early attention pays.
Why act early in Green Street Green
A noisy fan rarely fixes itself. Bearings that are left to wear can fail suddenly and the fan may stop when you’re busiest. Sorting it while it still runs is far easier to plan. A busy site in Green Street Green builds up dirt and wear quickly, so putting it off makes the eventual job larger.

What staff can safely do
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
