Free Cavity Wall Insulation For Electric Heated Properties

Get free cavity wall insulation if your home has electric heating

If your home is heated by electric storage heating or room heaters you can save up to £1000 per year on energy costs via a Government grant scheme. The Energy Company Obligation (ECO) provides 100% non-repayable grants to home owners , private tenants and landlords throughout Scotland. The scheme is designed to help reduce carbon emissions and lower energy costs for those who live in both rural and urban areas.

ECO home insulation grant scheme

The ECO insulation scheme was introduced in 2013. Since its introduction hundreds of thousands of households across the UK have taken advantage of energy efficiency measures including cavity wall insulation, loft insulation and replacement boilers. The scheme is backed by the Government and the “Big six” energy providers provide the funding for any measures carried out.

ECO is split into two individual components

  • Carbon Emissions Reduction Obligation (CERO) Under CERO, obligated suppliers must promote ‘primary measures’, including roof and wall insulation and connections to district heating systems. Some CERO must also be delivered in rural areas.
  • Home Heating Cost Reduction Obligation (HHCRO)Under HHCRO, obligated suppliers must promote measures which improve the ability of low income and vulnerable household to heat their homes. This includes actions that result in heating savings, such as the replacement or repair of a boiler. OFGEM

The CERO component provides wall insulation for larger properties and properties which are off-grid (where mains gas is not the priomary heating source). This includes households with alternative heating methods including electric storage heating, electric boilers, oil, LPG and solid fuel. These types of properties are normally found in rural areas but grants can also be claimed for properties in urban areas in Scotland. CERO is designed to help lower the emissions generated by heating larger properties with high carbon fuels.

CERO wall insulation grants are not means tested so you do not have to claim benefits to be eligible.

HHCRO is designed to help those deemd to be living in “fuel poverty.” This component providers free cavity wall insulation and loft insulation for households who claim the following benefits or tax credits –

  • Pension Guarantee Credit
  • Child Tax Credit
  • Working Tax Credit
  • Income Support
  • Income-based Job Seeker’s Allowance
  • Income-Related Employment Support Allowance
  • Universal Credit

If you claim Child Tax Credit, Working Tax Credit or Universal Credit your income must be below a certain threshold to qualify for free insulation:

Electric heating in Scotland

There are many regions in Scotland which are not linked up to the gas  grid. In these areas households are forced to choose an alternative way of heating their homes. Electric storage heating, oil, LPG and solid fuel heating is normally more expensive than gas. So it is important to use the money you spend on energy efficiently.

Taking measures to reduce heat loss in your home can substantially reduce the money you spend on heating bills. Most of the heat you generate from your heating is lost through the outer walls of your home (35%). In addition, around a quarter (25%) escapes out through your attic and roof. Installing adequate loft and wall insulation can reduce your energy bills by up to 40% during the cold winter months.

Are you off the gas grid?

Cavity Wall Insulation

Cavity Wall Insulation

Depending on your property type you may be able to have cavity wall insulation installed in your home. Many homes built after the 1920s were built with a gap between two skins of bricks as a way of protecting your living space from the cold. However by placing insulating materials in the cavity you can give your home an extra layer of protection. As 35& of heat escapes through your outer walls, insulating them is one of the most effective ways of conserving the energy you generate with your central heating.

If your home is properly insulated then benefits include –

  • Reduced heat loss
  • Lower energy costs
  • your home is warmer
  • lower carbon emissions
  • improves the energy rating of your property
  • 100% free installation
  • 25 year guarantee
  • government approved installers

Applying for free cavity wall insulation is a straightforward no hassle process

Scottish Energy Grants have approved energy surveyors in all regions of Scotland. Give us a call or leave a few details and we will arrange a home visit. This should only take about an hour. If your property is suitable for wall insulation we will arrange for a Government approved installer to fit your free insulation. We aim to survey properties that qualify in the Glasgow, Edinburgh or Central Scotland area within 5 working days. In other Scottish regions it may take up to 14 days.
