1. In 2017, Scottish House Condition Survey data reported 42% of homes achieved band C rating under SAP 2012, up from 35% in 2014. Using SAP 2009, 46% of dwellings were rated C or better, up 22 percentage points since 2010. In the same period, properties in the lowest EPC bands (E, F or G) have reduced from 27% in 2010 to 13% in 2017

22. A SAP calculation indicates a score from 1 to 100+ for the annual energy cost, where the higher the score the lower the running costs, with 100 representing zero energy cost. Dwellings with a rating in excess of 100 are net exporters of energy.

52. There are currently 36 live infill projects looking at extending gas network provision to new areas in Scotland, which could potentially connect 4,719 new properties to the gas mains. These are driven by the economic advantages for consumers of using gas to heat their homes and businesses rather than oil, solid fuels or electricity, with around 1,700 supported by the Fuel Poor Network Extension Scheme
