Barwell replaces Brandon Lewis who acted as housing minister from 2014 to 2016 and has now been appointed minister of state for policing and the fire service.
Barwell was elected MP for Croydon Central in May 2010 after working as chief operating officer for the Conservative Party and running his own consultancy business. As well as being named housing minister, he will also act as minister for London.
His responsibilities will now include housing, planning policy, neighbourhood planning, lead minister on the housing bill and planning casework, and will carry out the role under the Department for Communities and Local Government.
Writing on Twitter, Barwell said: “Hugely honoured to have been asked by the Prime Minister to serve as Minister of State for Housing and Planning and Minister for London.
“Look forward to working with councils, housing associations, developers and investors to ensure we build the homes people need and deserve…and to working with @MayorofLondon to ensure the continued success of our wonderful, diverse capital – and that all Londoners share in it.”
