Subsidiary MCI is reopening another 11 sites.

Keepmoat closed all of its construction sites at the end of March and furloughed some of its staff.

Keepmoat has 1,150 directly employed staff and over 10,000 indirectly employed in its supply chain.

Chief executive officer Tim Beale said: “The Government recognises the construction industry as a cornerstone of the UK economy and a major employer.

“It knows we have the skills and procedures to manage safety on site and trusts us to be in the vanguard of the return to work.

“Despite the pressure to continue meeting local and national housing need, we have had overwhelming support from our local authority and housing association partners in prioritising the safety of our colleagues.

“The needs of first time buyers for an affordable first step on the housing ladder are unchanged.

“We have seen continuing demand for new homes and are ensuring that homes are available to buy as consumer confidence returns.”

Keepmoat highlighted “potential problems for the housebuilding industry in the supply of essential construction materials, the connection of utilities, the availability of mortgages and the valuation of homes for mortgage purposes.”
