Nest Wales (New Fuel Poverty Scheme)

Nest is a Welsh Government programme designed to help people who are finding it difficult to pay their energy bills.

The scheme replaces HEES and focuses on improving the energy performance of a home through installing measures including loft insulation, cavity wall insulation etc.


What is Nest?

Nest is a Welsh Government Scheme which replaces HEES. It is designed to make private sector households warmer and healthier places to live. Nest aims to improve the energy performance of households which are living in fuel poverty. Fuel poverty is defined as people who spend more than 10% of their household income on heating their home.

As well as support in accessing energy efficiency improvements, Nest also provides callers with guidance on benefit entitlement, energy tariffs and money management through a range of expert partners.

British Gas is the delivery partner of the scheme and its team of experts from across Wales visit eligible properties to conduct a Whole House Assessment before suggesting, agreeing and installing a range of measures suitable for that home and its occupants.

To be eligible for Nest, householders must:

  • own or privately rent their home
  • be in receipt of a means-tested benefit, and
  • live in an energy inefficient property with an energy efficiency rating of F or G.

Am I eligible for Nest?

Are you struggling to pay your bills? Are you receiving a means tested benefit? Is your home privately owned or rented? If you meet this criteria and your home has an energy efficiency rating of F or G you may be eligible for a range of measures to improve the energy performance of your home.

What does F or G rated mean?

The Standard Assessment Procedure (SAP) is used to calculate a household energy efficiency rating on a scale of 1-100- with 100 being the most efficient and 1 the least. This scale is converted into bands- A to G- where A is the most efficienct and G the least. Properties with a SAP of 38 points or less are in the F or G rating, and therefore qualify for Nest.

How do I know if my house is F or G rated?

There are many different factors which affect a household's energy efficiency rating, and only a SAP survey carried out in the home can confirm a household's rating. However, as a guide, properties in the F or G band would typicall have all, or most of, these characteristics:

  • No central heating, or a central heating system with a very inefficient boiler. Usually, this would mean a 15+ year old boiler, but some newer boilers may also be inefficient
  • An un-insulated hot water cylinder
  • Solid Walls, un-insulated cavity walls, or walls of a non-traditional construction type
  • Less than 100mm of loft insulation
  • Single glazed windows
  • No low energy light bulbs or draughtproofing

Homes where the main heating system uses a fuel other than mains gas, and detached, semi-detached or end-terrace properties are more likely to be F or G rated.

What are the means tested benefits?

To qualify for Nest, the householder must be in receipt of one or more of the following benefits:

  • Child Tax Credit where the household income is below £15,680
  • Council Tax Benefit (excluding the single person occupancy reduction)
  • Housing Benefit
  • Income Based Job Seekers Allowance
  • Income Support
  • Pension Credit
  • Working Tax Credit where the household income is below £15,680
