The Nest Annual Report for 2017/18 shows more than 15,600 householders received energy advice and support, including referrals to third party services such as benefit entitlement checks to maximise their household income. The total number of households provided with advice and support is more than 112,600 during the seven years the Nest scheme has been running. In 2017/18, more than 4,600 of the most energy and thermally inefficient homes received energy efficiency measures through the scheme. After the installation of measures, 79% of properties were increased to an energy efficiency rating of between B and D, with a further 18.9% to an E-rating and 2% to an F-rating. Since its launch, more than 33,900 homes across Wales have benefitted from home energy efficiency improvements.
In homes receiving new central heating boilers under the Nest scheme, a service visit is undertaken at no cost to the homeowner one year after installation to ensure the boiler is operating efficiently and safely. For homes benefitting from cavity or solid wall insulation, the homeowner receives a 25 year industry backed guarantee, which safeguards against any defect arising from the design, workmanship or materials installed. Nest provides a complete aftercare service to resolve any issues following installation of the measures agreed with homeowners. In 2017/18, Nest put in place remedial action in 7 homes following complaints made by the householder. Following the installation of home energy efficiency measures, further advice and ongoing support is available through the Nest helpline.
