External Wall Insulation

External wall insulation wraps your home in a continuous thermal jacket, reducing heat loss by 35–40% and protecting brickwork from weather damage. It’s a standard ECO4 measure for solid walls and a one-measure option under GBIS.Â

• Who qualifies: 
  – Solid-walled properties with EPC D–G and households on benefits or council-tax bands A–E.Â

• What’s involved: 
  – Structural survey, planning check if in conservation areas. 
  – Scaffold erection; application of 100–150 mm insulation with render or brick-slip finish. 
  – Final rendering/cladding and ECO4/GBIS funding submission.Â

• Benefits: 
  – Lower heating bills and façade renewal. 
  – Damp prevention and improved curb appeal.Â
