Target Government Areas

EPI Policy Levers

Each slider = % of at-risk households reached by the policy. E.g. "Heating 40%" means 40% of homes without central heating receive one. Effect on IREPO = reduction × indicator weight × 0.5 (EPI's share of composite). EPI weights shown in brackets. Max values reflect realistic policy ceilings.

🔥 Heating Upgrade Programme

% of unheated homes receiving central heating (w: 25%)

🪨 Solid Fuel Phase-Out

% of solid fuel homes switching to cleaner heat (w: 20%)

🛢️ Oil Heating Transition

% of oil homes switching to heat pump / gas (w: 10%)

☀️ Renewable Energy Rollout

% of homes receiving on-site renewable generation (w: 10%)

🏠 Social Housing Retrofit

% reduction in LA renting risk exposure (w: 10%)

💼 Employment Programme

% reduction in unemployment rate (w: 5%)

BER Building Performance Scenario

% of assessed dwellings receiving a BER upgrade (shifting their rating upward). Because BER accounts for 50% of the composite IREPO score, this lever has the largest single impact — which correctly reflects the methodology. The EPI levers combined cover the other 50%. Max 80% reflects SEAI Warmer Homes programme ambition ceiling.

National Retrofit Ambition

% of dwellings receiving BER upgrade (composite weight: 50%)
