Energy Grants for Cardiff Homeowners

Cardiff's housing stock spans from Victorian and Edwardian terraces in areas like Canton, Splott, and Cathays to interwar semis in Whitchurch and Rhiwbina, and newer developments in Cardiff Bay. Many of the city's older homes have solid walls, poor loft insulation, and inefficient heating systems. The Welsh Government has set ambitious targets for decarbonising housing, and Cardiff homeowners can benefit from both UK-wide grant schemes and Wales-specific programmes like the Warm Homes Nest scheme.

EcoEnergy247 supports Cardiff homeowners in accessing ECO4 and GBIS grants, as well as providing guidance on Welsh Government energy programmes. Our South Wales installation teams are experienced with the terraced housing that dominates many Cardiff neighbourhoods and understand the specific construction methods used in Welsh housing. From free boiler replacements in Grangetown to cavity wall insulation in Llanishen, we help Cardiff residents reduce their energy bills through funded improvements.
