    Behind The Walls | #9 with Eoin McGann

    26/11/2025 | 41 mins.
    In this episode, we sit down with Eoin McGann from EMG Energy Consultants to break down everything you need to know about home energy assessments. Whether you're considering a retrofit, thinking about installing a heat pump, or just want to understand where your home stands energy-wise, this is the episode for you.
    Eoin walks us through the entire process from start to finish, explaining what assessors actually look at when they visit your home, how the roadmap system works, and why getting your assessment done is the essential first step on your retrofit journey. We also discuss the Heat Loss Indicator (HLI), why it matters for heat pump eligibility, and how the industry has evolved over the years.
    Pete shares his own experience having Eoin assess his 20-year-old home, and we explore why every homeowner in Ireland should seriously consider getting their home energy assessment done while the grants are still available.
