Introduction to the Framework

The new Retrofit and Decarbonisation Framework (N9) will be the successor to LHC's successful Energy Efficiency Measures & Associated Works (N8) Framework which expires November 2024.

The framework has been designed to support clients with delivering a range of energy efficiency and decarbonisation works helping them with their journey to achieving net carbon zero and improving the EPC ratings of their stock.

With over 30 years experience delivering energy efficiency and retrofit solutions to the public sector, we held our Pre-Tender Engagement webinar on the 20th of September, if you missed it you can now re-watch the full webinar to the right.

Join LHC in shaping tomorrows net zero future.
