“Planning permissions granted for new homes are being concentrated in the wrong areas, where there is less need for housing, according to new research by Savills.
It found that there is a lack of 90,000 planning consents for homes in the least affordable and most in-demand areas of the country.
Only 20pc of planning consents in 2016 were in the most unaffordable places, where the lowest priced homes are at least 11.4 times income. However, 40pc of the country’s total need for new homes is in these markets, while there is a surplus of consents in the most affordable locations.
Research found that in areas where the house price to earnings ratio is over 11.4, which includes London and much of the South East, there is a shortfall of 73,000 planning consents for homes.
Since the National Planning Policy Framework was launched four years ago, with the aim of simplifying the system, there has been a 56pc increase in the number of consents granted.
But analysis shows that there has not been any increase in the areas where affordability is most stretched and where housing need is the greatest.
The Savills report said: “This means we are not building enough homes in areas where they are most needed to improve affordability and support economic productivity.”
Only 41pc of local authorities have a housing plan which sets out housing need and a five-year plan of how to cater for it.
Savills also modelled the potential impact of the Housing Delivery Test, which was announced in the Housing White Paper last February and would assess need based on market strength in an attempt to build “homes in the right places”. It found that it would double London’s housing need to more than 100,000 homes.
Chris Buckle, Savills research director, said: “There continues to be a massive shortfall in London and its surrounds and it is this misalignment of housing need versus delivery which could ultimately hinder economic growth.”
