Boyer reduces CIL rate to nil

04th July 2016

Boyer’s Development Economics team was engaged to make representations against the Royal Borough of Windsor and Maidenhead’s (RBWM) £150 psqm large office CIL rate. In his report of the 13 June 2016 the Examiner, using much of Development Economics’ evidence, determined that the office CIL rate was unjustified and reduced it to Nil. The main arguments successfully put forward by our Development Economics team included–

  • The Council’s evidence wrongly calculated office scheme value based on Gross Internal Area (GIA) rather than Net Internal Area (NIA) resulting in over inflated Gross Development Values (GDVs) of between 15%-20%;
  • The benchmark land value, especially in prominent office locations such as Maidenhead, used in the Council’s analysis were too low and not reflective of existing use values nor market reality; and
  • The evidence used disregarded the Council’s own local plan policies which promoted office development in key locations such as Maidenhead town centre.

In reducing the large office CIL rate from £150 sqm to Nil office schemes greater than 2,000 sqm of new office floor space could save up to £300,000.
