Six new non-executive directors are to be appointed to NHS Improvement in a major shake-up of its board.

Four of the vacancies are because current non-executives are reaching the end of their term and two positions have been vacant for some time.

The non-executives whose terms expire this year are: Lord Carter; Lord Darzi; Sigurd Reinton; and Sarah Harkness.

Their departures combined with the two vacant posts – last occupied by Caroline Thomson and Laura Carstensen – will leave Richard Douglas and Dame Glynis Breakwell as non-executives and David Roberts as an associate non-executive.

With so many appointments to be made at the same time, new NHSI chair Baroness Harding will have a rare opportunity to help shape her own board. She is on the three person assessment panel for the roles, alongside Lee McDonough, a director from the Department of Health and Social Care, and NHS Digital non-executive Professor Sudhesh Kumar.

In a message for applicants, Baroness Harding said NHSI is looking for people “with considerable experience of leading transformational change in large organisations, who are collaborative and open minded and keen to be part of a diverse team of executives and non-executives.”

Among the skills it is looking for are experience of “property transformation”.

NHSI non-executives cannot be appointed for more than four years but they can be reappointed for additional terms.

Odgers Berndtson has been appointed to help with recruitment. The closing date is 8 May.
