Government policies have contributed to the housing shortage through:
immigration
deregulation
second homes/holiday homes
Immigration:
large-scale immigration from the EU, especially since 2004, contributed to increasing the UK population from 59 million in 2001 to 63 million by 2011. An open-door immigration may have economic benefits but it also creates demand for new houses.
Deregulation:
the UK is very open to foreign investment, including allowing foreign people and companies to buy property.
In 2016, the Guardian estimated that 40,000 London properties were owned by offshoretaxhavens. These properties may not be lived in, or even rented.
Allowed any bank or financial advisor to trade in shares on the London stock exchange.
Barriers stopping banks and other financial institutes from setting up offices in London were also removed
Second homes and holiday homes: there are few restrictions in the UK on people buying houses to rent out, e.g. as a holiday let or buying a second home. In some rural areas a large percentage of houses may not be available to local people.
The main economic arguments for immigration are:
Increased gross domestic product (GDP)
Extra taxes and production
Both well-qualified and lower-skilled immigrants can fill skills shortages
high levels of net migration can also hinder regeneration:
Increased pressure on services and housing availability in certain areas
Social issues caused by asylum seekers being housed in hard-to-let properties in already deprived areas, such as estates in Middlesbrough
