Do Kitchen Extractor Fans Need to Vent Outside? [Quick Guide]

Many people got confused while installing the extractor hoods. As they aren’t sure if kitchen extractor fans need to vent outside or not? So, if you’re also confused, here is your quick answer:

Kitchen extractor fans have been a legal requirement in the UK since April 2006. But, an extractor fan doesn’t have to vent outside. There is no legal requirement for an outside vent, but it is considered a best practice if the fitted hood vent is outside.

Range hoods are designed to remove the cooking odors, grease particles, and other pollutants released into the air while you cook. It might not be possible for many homeowners of Central London or Brits living in flats. Well, they can extract stale air through a ducted range hood. 

Before diving into details, let us give you a general overview of different extraction units and other essential information you should know.

Do Kitchen extractor fans need to vent outside building regulations?

There were no regulations about ventilation. Since April 2006, extractor fans have been a legal requirement in the U.K. If you renovate or build a new home, it is a legal requirement.

In March 2019, the new homes act came into force. It was a recent amendment to the landlord and Tenant act of 1985. 
The landlord must ensure a dehumidifier, a new extraction hood, or a fan for proper kitchen ventilation. Without a dehumidifier or ducted hood, you would often be cleaning dirty kitchen tiles due to food debris and smoke particles.

What is the difference between recirculating hoods and extraction hoods?

When unclear air is pumped out from the kitchen or apartment by ducting in, an outside wall to the air outside is known as extraction.

The recirculation process is practised when it is not possible to vent externally. The air is sucked, filtered, purified, and then pushed back into the room. Such hoods also work as steam & grease filters.

Most ductless range hoods have a built-in carbon filter and charcoal filter. But, they did not go well with the small kitchens and the home’s exterior. Using them in a small kitchen can cause several problems, i.e., stale air and humidity.
