Results are estimates based on NIWA climate data and industry average U-values; your actual savings depend on house design, heating system, and behaviour. WGANZ sets a 15-year durability requirement for all windows (including uPVC) under the NZ Building Code (Clause B2), but indicates that they can last 40-50 years. Raw modelled monthly saving assumes a heat pump with COP = 3 and $0.34/kWh electricity price.
