One of the inventors of the controversial Merton Rule has been poached from Merton council by a small planning and architecture firm.

Adrian Hewitt will head Metropolis Green, the new sustainability division at London-based Metropolis Planning & Design from June.

The division will compile and file energy and sustainability reports for local councils with planning departments.

Hewitt follows Miranda Pennington, Islington’s green liaison officer, to the firm.

He was one of three founders of the Merton Rule, the policy that in 2003 set a 10% renewable energy quota for new developments.
