Four arrested in dawn raid over suspected ECO4 home insulation scheme fraud

Four people were arrested during a dawn raid as part of a Serious Fraud Office investigation into suspected fraud linked to the government's ECO4 home insulation scheme. The SFO says a £44m fraud may have been attempted, with evidence gathered from multiple locations. Background details show ECO4 aimed to help vulnerable households but faced widespread concerns and subsequent investigations.

Why It Matters

The ECO4 scheme was a major government initiative to improve energy efficiency for vulnerable households. The arrests and investigation raise questions about oversight, accountability, and the integrity of publicly funded energy measures.
