Insulation & Rendering Specialists Across South Wales & The South West
Based in Ferndale, we deliver fully compliant PAS 2030 retrofit installations, advanced external wall insulation, and architectural rendering across a 50–60 mile operational radius.
Reliable Energy-Efficiency Upgrades Right to Your Doorstep
At Global Energy Insulation, we believe every property deserves to be warm, dry, and energy-efficient. Operating from our central headquarters in Ferndale, Rhondda Cynon Taf, our expert teams cover a 50–60 mile radius across South Wales and South West England. We specialise in treating solid walls, non-traditional builds, and standard masonry homes to dramatically reduce high energy bills and stop thermal bridging.
Because complete retrofits require flawless execution inside and out, we work in tandem with our sister company, Global Plastering. While we install your External Wall Insulation (EWI) or high-performance Internal Wall Insulation (IWI), Global Plastering provides comprehensive traditional plastering, drylining, and skimming. This collaboration delivers a seamless, end-to-end service with single-point accountability.

Our Operational Location & Local Guidance
Based centrally in Ferndale, South Wales, we are exceptionally well-placed to handle the unique microclimates of the region. Heavy Welsh rain and coastal winds in the South West demand weather-resistant exterior finishes, which is why our high-performance silicone rendering systems and insulated render systems are engineered for lasting durability.
We handle all aspects of local authority compliance, listed building considerations, and conservation area guidelines when planning external alterations like EWI.
Note for Landlords: Under MEES guidelines, domestic rental properties must meet minimum EPC ratings. We specialize in fast-turnaround assessments and energy upgrades to keep your portfolio compliant.
