Our mission and values
Your personalised retrofit plan. without leaving your home.
Retrofit with confidence, not guesswork.
Effici makes upgrading your property’s energy performance simple. In just minutes, we show you exactly what to improve, how much you’ll save, find eligible grants and connect you with trusted professionals – all without costly surveys or delays.
Share your EPC, bills, floorplans plus our smart questionnaire. No floorplans? No problem. Our in-app LiDAR scan turns your phone into a 3D modelling tool, giving us precise heat load and heat loss calculations so your retrofit is never under- or over sized.
Every detail we gather feeds into our machine learning engine, delivering a tailored plan or comparing your chosen upgrades side by side, complete with costs, payback, environmental impact, and expected disruptions.
