Kensington and Chelsea top district for home improvement
This comes after the latest English Housing Survey revealed that up to three quarters of UK homes are more than 50 years-old.
Blackpool is at the bottom of the list with only 0.4 planning applications for every 100 private homes, followed by West Dunbartonshire and Stoke-on-Trent.
Applications increased by 14% in the East of England, which was the largest national growth, and more than 100,000 applications were submitted to London planning authorities in 2016.
Martin Smith, managing director of Showerstoyou.co.uk, said: “It is interesting to see planning applications are on the rise, but it is by no means surprising.
“In an unsteady climate, homeowners are realising the power of the property they already own. By investing in their home they remain secure and in control of their own profits, with no need to face a tumultuous housing market.”
