Brexit uncertainty will dampen tender price growth across the UK this year and will continue into the early part of 2019 as negotiations between Theresa May’s government and officials in Brussels grind on, according to a new report.

The latest global data research from cost consultancy Rider Levett Bucknall said that while construction output remained high in the UK, the outlook was “clouded” by the uncertainty around negotiations with Brussels and the looming deadline of 29 March 2019, when the UK leaves the EU.

RLB’s tender price index showed that only Bristol will show signs of growth in 2018, boosted by an upturn in residential development, while Leeds and Sheffield were heading into deflation territory, although RLB’s figures suggested both Yorkshire cities would bounce back in 2019.
