Key People

The CHS Group Board and Executive team is made up of experienced individuals with extensive knowledge of the different elements of housing provision, management and social enterprise.

Our Board is drawn from the local community and is supported by five key committees: Operations; Audit & Risk; New Business & Development; Governance; and HR & Remuneration Committee. There are two further groups that strengthen our commitment to draw upon our tenants’ skills and experience – the Customer Committee, which sets its own agenda and makes recommendations on service policies and standards, and a tenant-led Scrutiny Panel which has the remit to review any part of our operation and make improvement recommendations to the main Board.


CHS is required to meet the relevant standards published and regulated by the Regulator of Social Housing. CHS’s Board is responsible for meeting the standards and being transparent and accountable for the delivery of our social housing objectives.
