Premises

The council inherited two main offices from its predecessor authorities: Ystrad Fawr House at Ystrad Mynach from Rhymney Valley District Council, and Pontllanfraith House in Pontllanfraith from Islwyn Borough Council. Ystrad Fawr House was demolished in 2008 to make way for the Ysbyty Ystrad Fawr hospital. A new headquarters was built at Penallta House in the Tredomen area of Ystrad Mynach (in the community of Gelligaer), opening in April 2008. The other office at Pontllanfraith House subsequently closed in 2015 and has since been demolished.

Allegations of misconduct

In 2015 Anthony O'Sullivan, the chief executive and two other executives were charged with misconduct during public office. It was alleged that they specifically 'wilfully misconducted themselves in relation to securing Caerphilly County Borough Council's approval of a remuneration package for the said council's chief officers from which they stood to gain for themselves'. Relating to this and other failings the Welsh Assembly commissioned a special report on the council in January 2014
