If you're a homeowner wondering when to retire gas appliances, what to switch to, whether to do it all at once or one at a time, how to fund it, and whether it's even worth it—you're not alone. 

At Sustainability Trust, we've been operating in the home efficiency space for 23 years. Last financial year alone, we visited more than 7,500 homes in the Wellington region. Through this work, we constantly hear questions about electrification and know that many homeowners don't know where to start.
