We are committed to maintaining the highest standards of governance and comply with the principles outlined in the Code of Governance for Voluntary Organisations, which is approved by the Charity Commission.

The executive team prepares matters such as policy, strategy and budgets for consideration and approval by the trustees, who then monitor the implementation of these plans.

Alison Pike - Executive Director of Inclusive Communities & Partnerships - Communities

Ali’s career started in the east of London as a secondary school teacher on the Teach First programme. After 3 years of teaching and some extensive travelling in central and south America she dabbled in the private sector working as a management consultant for Deloitte.  

In 2010 she ventured into the charity sector and hasn’t looked back! Since then she has developed a keen interest in community inclusion: she is enthusiastic about people having the agency, connections and support they need to be able to live, work, socialise and really enjoy life to the full in the community they call home.  

She feels lucky to be able to focus on this day to day at Mencap. Ali loves the diversity of her role and the impact that the work of the directorate clearly has on the lives of people she meets across England, Northern Ireland and Wales.
