The rise in the cot of building materials is high than at any time in the last 40 years, according to the latest Building Cost Information Service Materials Cost Index.
Between January and September 2021 the biggest rises were for steel and timber and the increases are unlikely to stop there.
James Fiske, Director of BCIS, said: “The cost of materials in constructing a 3-bedroom semi-detached house has increased by 14% or approximately £7,300 between January and September 2021. It is expected to grow by further 1% or £600 by the end of this year.”
