More credence should have been given to RHI concerns, says the North’s Civil Service chief

The overspending RHI led to the collapse of powersharing at Stormont 13 months ago after former deputy first minister Martin McGuinness resigned over the DUP's handling of the affair.

More credence should have been given to concerns about the North’s Renewable Heat Incentive (RHI) scheme, the head of the Northern Ireland Civil Service said.

Janette O'Hagan was selling a heat efficiency product in 2013 but found potential customers were not interested after they had signed up for the botched green energy scheme. She raised the alarm over potential misuse.
