Questions have been raised over the “approach to transparency” of Northern Ireland’s gas and electricity regulator.
A public inquiry into a botched green energy scheme, which sparked political chaos in the region after its costs spiralled, has been examining the handling of an application from a Democratic Unionist special adviser.
Ofgem received anonymous allegations of fraud in the application by Stephen Brimstone for the Renewable Heat Incentive.
The result was an anticipated massive overspend, falling to the Northern Irish taxpayer to pick up.
Mr Brimstone applied for the scheme after installing a new biomass boiler in a shed next to his home which provided heat to both buildings.
Ofgem audited Mr Brimstone’s RHI boiler and concluded he joined the scheme legitimately.
However the inquiry heard on Wednesday that Ofgem did not provide all the documentation it held about Mr Brimstone’s application to the Police Service of Northern Ireland when it launched an investigation into allegations of fraud.
Ofgem lawyer John Jackson told the inquiry in a written witness statement that there was “nothing in the documents, or the conclusions that they reached, that would’ve assisted the police in a criminal prosecution of Stephen Brimstone”.
No crime was detected by police during its investigation.
He put to the panel: “The inquiry may want to consider whether that’s an illustration of wider cultural issue about Ofgem’s approach to transparency and information sharing.”
The RHI Inquiry led by retired judge Sir Patrick Coghlin will make findings at a later date.
On Wednesday the inquiry returned to Stormont where Mr Aiken said closing oral submissions will be heard over three days.
These include from the three core participants – the Department for the Economy, Department of Finance and Office of Gas and Electricity Markets (Ofgem).
Oral submissions will also be heard from some of the 27 individuals and organisations who were granted enhanced participatory rights.
Among those are Democratic Unionist leader Arlene Foster, former Democratic Unionist minister Jonathan Bell, a number of the party’s special advisers and some senior civil servants.
The inquiry will hear Ofgem’s closing statement on Wednesday afternoon.
