The Nest scheme offers Welsh residents a package of free home energy efficiency improvements, including cavity wall & pitched roof insulation.

If you are looking to improve your home’s energy efficiency through insulation measures, Smartstone can quickly and easily ensure you claim any funding you are entitled to as part of the Welsh Government’s Warm Homes programme.

If your home is hard to heat, you could be entitled to insulation at no cost to you.

You could be eligible for free energy efficiency improvements if:

  • You own your home or rent from a private landlord (not Council or Housing Association)
  • Your home is energy inefficient and expensive to heat
  • You or someone you live with receives a means tested benefit OR has a chronic respiratory, circulatory or mental health condition and an income below defined thresholds

As this is a grant, and not a loan, it doesn’t need to be repaid and will ensure it is cheaper to heat your home and keep it warm over the long-term

Any insulation measures are carried out by government Trustmark-approved installers.


Please read through the following eligibility criteria carefully. You may need to provide some further evidence such as a benefit award letter and, if applicable, your landlords details By doing so, our expert advisors will be able to process your details more swiftly.

You could be eligible for free home energy efficiency improvements if you meet all three conditions below:

  1. You own or privately rent your home (not from a local authority or housing association)
  2. Your home is energy inefficient and expensive to heat
  3. You or someone you live with receives a means tested benefit OR has a chronic respiratory, circulatory or mental health condition and an income below the defined thresholds


The means tested benefits that qualify are:

  • Child Tax Credit (income below £16,105 a year)
  • Council Tax Reduction (exemption and discount do not qualify on their own)
  • Housing Benefit
  • Income-based Jobseeker’s Allowance
  • Income-related Employment and Support Allowance
  • Income Support
  • Pension Credit
  • Universal Credit
  • Working Tax Credit (income below £16,105 a year)

Health eligibility criteria

Alongside the current criteria for people in receipt of a means tested benefit, the new health criteria for free energy efficiency home improvements are:

Someone in the home must:

  • Be living with a chronic respiratory, circulatory or mental health condition.These include:
    • Respiratory disease (respiratory infections, broncho-constriction in asthma, and chronic obstructive pulmonary disease)
    • Circulatory disease (including cardio-vascular disease, strokes and heart attacks)
    • Mental health issues (including depression, anxiety, psychosis and bipolar disorders, dementia, intellectual and development disorders).
  • Be living on a low income below the defined thresholds

In a drive to improve the energy efficiency of Britain’s homes and reduce our carbon footprint, government initiatives can provide £1,000s in home insulation grants to make energy efficiency improvements to your home.

The tricky part is determining your eligibility requirements and how much you are entitled to, especially as new schemes come into effect and can vary from region to region. This can often result in many households making contributions where they don’t need to, or worse, missing out on funding entirely.

Smartstone’s Free Eligibility Check is here to help! We’ll assess your personal circumstances and your home to help you secure the maximum amount of energy funding across all available government grants for home insulation.
