The Welsh Government Warm Homes Nest Programme

The Welsh Government Warm Homes Nest scheme is designed to help households across Wales lower energy bills, improve property warmth, and reduce carbon emissions. Operating as the flagship domestic decarbonisation initiative in Wales, Nest provides free, impartial advice alongside grant-funded physical improvements.

Since 2011, Nest has provided over 60,000 households with free home energy improvements. These measures encompass advanced heating systems, cavity and solid wall insulation, and rooftop solar panels to help lower energy bills and improve health and wellbeing.

Available Improvements: Solar PV, Heat Pumps, and Insulation

When an applicant contacts Nest, advisors conduct a comprehensive energy assessment to evaluate whether the property qualifies for capital improvement grants. If eligible, Nest recommends a tailored package of improvements:

• Rooftop Solar Panels: Turnkey installation of domestic solar PV systems to generate clean electricity on-site.
• Low-Carbon Heating: High-efficiency heat pumps (such as air source heat pumps) to replace inefficient fossil-fuel boilers.
• Fabric Insulation: Loft insulation, cavity wall insulation, and external or internal solid wall insulation.
• Emergency Heating Upgrades: If a property is without heating or hot water, eligible households can receive immediate repairs or replacements for boilers or electric storage heaters.

Eligibility Criteria and Council Tax Valuation Bands

Eligibility for fully funded Nest improvements is targeted at households experiencing fuel poverty or health vulnerabilities exacerbated by cold living conditions:

Household Income and Means-Tested Support

Eligible households typically include private owner-occupiers and private renters in receipt of a qualifying means-tested benefit, or individuals suffering from chronic health conditions affected by cold housing. Private tenants must secure their landlord's consent prior to installation.

Property Efficiency and Valuation Bands

Dwellings must have an Energy Performance Certificate (EPC) demonstrating poor energy efficiency (typically EPC bands E, F, or G). Under broader statutory energy frameworks operating in Wales—such as the ECO4 and Great British Insulation Scheme (GBIS) regulations codified in Statutory Instrument 2023 No. 873:

• Support covers private domestic premises in council tax valuation bands A to D in England, or A to E in Wales or Scotland.
• Eligible properties include homes with an Energy Performance Certificate rating of D-G, occupied by low-income and vulnerable households or members of the statutory help to heat group.

0% VAT Relief for Domestic Solar and Storage in Wales

In addition to direct scheme funding, Welsh householders investing in microgeneration benefit from the UK-wide statutory 0% VAT relief set out in HMRC VAT Notice 708/6:

• Temporary Zero Rate Period: A zero rate applies to the installation of certain specified energy-saving materials from 1 May 2023 to 31 March 2027.
• Installation and Materials Scope: The relief covers both the services of installing energy-saving materials in residential accommodation and the supply of goods provided by the installer.
• Solar Photovoltaics: Includes complete systems comprising photovoltaic (PV) panels with cabling, balance-of-system control panels, and AC/DC inverters.
• Battery Storage: From 1 February 2024, electrical storage batteries installed in residential accommodation benefit from the temporary zero rate of VAT.
