Local Insight
Most Victorian and Edwardian London homes have solid walls (no cavity) — these lose up to 45% of heat through the walls. Internal wall insulation is the most practical solution for terraced houses where external insulation would change the street appearance. Loft insulation is the cheapest and most effective upgrade — it pays for itself within 1–2 years through energy savings.
