NCC has secured funding through the Government's Warm Homes: Social Housing Fund (WHSHF) and Warm Homes: Local Grant (WHLG) schemes to upgrade homes across Northumberland. The Warmer Homes Team is working to improve domestic energy efficiency, reduce fuel poverty, lower household energy bills, and help properties achieve EPC Grade C ratings by 2030. Consultants will provide expertise in retrofit planning, design, and project delivery to support these objectives. This is an opportunity for experienced consultants to contribute to a major regional decarbonisation initiative.
