Scotland's Sustainable Housing Strategy

1. Every home to have loft and cavity wall insulation (where cost effective/ technically feasible) and draught proofing measures such as pipe lagging.

Every home to have loft insulation of at least 100 mm by 2020.

Figures from the Scottish House Condition Survey show that by the end of 2010 around 82% of lofts had at least 100 mm insulation and 36% had 200 mm or more.

Latest figures from the Scottish House Condition Survey show that by the end of 2011 around 86% of lofts had at least 100 mm insulation and 45% had 200 mm or more.

Every home to have cavity walls insulated, where appropriate and technically feasible.

Nearly two-thirds (62%) of cavity walls had been insulated.

Two-thirds ( 66%) of cavity walls had been insulated.

2. Every home heated with gas central heating to have a highly efficient boiler with appropriate controls.

The RPP assumes over 1,000,000 boiler replacements over the period from 2008-2020.

The Energy Saving Trust estimates that more than 128,000 new gas boilers were installed in Scottish homes between April 2010-March 2011 and around 120,000 between April 2011-March 2012. If this replacement rate continues until 2020 well over a million homes will have highly efficient new boilers.

The SHCS confirms this rate of gas boiler installations and upgrades; 125,000 homes reported having gas central heating installed or upgraded in the last year ( SHCS 2011).

3. At least 100,000 homes to have adopted some form of individual or community renewable heat technology for space and/or water heating.

The RPP assumes large scale uptake of solar thermal panels; biomass boilers; and heat pumps by 2020.

Around 13,000 homes had some form of renewable heat by the end of 2010 (Scottish House Condition Survey).

Energy Saving Trust ( EST) estimates that 10,800 micro-heat technologies had been installed by 2012. Space and/or water heating can also be provided by renewable electricity such as solar PV and the SHCS estimated that around 20,000 homes used solar thermal panels, biomass fuel or heat pumps by the end of 2011.

Provisional estimates from EST are that around 2,000 homes are connected to renewable district heating out of around 6,000 homes connected to community heating schemes.
