Respond to this consultation

Summary

DESNZ launches consultation on a £5 billion Warm Homes Fund offering government-backed loans and investments for domestic solar, batteries, heat pumps, and energy efficiency measures. The fund targets upfront cost barriers through financial transactions rather than grants. Consultation closes on an unspecified date seeking views from installers, manufacturers, housing providers, and finance institutions on fund design and target groups.

Why it matters

This addresses symptoms of expensive energy through subsidised finance rather than fixing supply constraints or market structure that make energy expensive. As such, it represents redistribution that may increase demand for technologies without addressing grid capacity or connection constraints that limit deployment.

Key facts

  • £5 billion government capital allocation
  • Covers domestic solar, batteries, clean heat, and energy efficiency
  • Financial transactions model (loans/investments, not grants)
  • Targets upfront cost barriers
