Retrofit guidance sources - cost and practices

I just came across this fabulous guidance on retrofit measures and associated cost. It is from the Hertfordshire Climate Change and Sustainability Partnership and published in 2024. I find it fabulous as it sort of aligns with some of the costs I am getting do a retrofit now in 2025, although costs have already gone up a bit. hccsp-retrofitting-your-house-guide.pdf (7.2 MB)
