There are a number of energy efficiency initiatives that can help qualifying households receive free or substantially subsidised insulation in Wales to make their property more energy efficient. The most prominent schemes for insulation in Wales are the Warm Homes Programme and the ECO4 Scheme.
The Welsh Government Warm Homes Programme offers to fund energy efficient home improvements for low-income households and disadvantaged areas across the region. The scheme supports the Welsh Government’s commitments to:
Are you finding it difficult to keep your home warm? You could qualify for the installation of energy efficient measures, such as insulation, at no cost to you. Through the various schemes you could receive a free boiler replacement (with an alternatives such as an air source heat pump) or free insulation — if you are on a low income and live in a property with EPC rating of E or below — to ensure the heat in your property is better retained and to lower your yearly energy bills. You could be entitled to free energy efficient measures like insulation if:
If you are entitled to home improvements, a package of energy efficient insulation measures will be recommended at no cost to you. This will keep your property warmer and save you money on your bills. .
Customers who have benefitted from a package of free energy efficient improvements in the past through the Welsh Government Warm Homes scheme are not able to receive any more energy efficiency improvements at the same property.
The means-tested benefits that are eligible for insulation grants are:
As well as the relevant criteria for people receiving a means-tested benefit, the new health criteria for free insulation grants in Wales, determines that to be eligible, someone in your property needs to:
When applying for free insulation funding through the scheme you need to confirm that you have proof of your health condition e.g a prescription, medication package, treatment plan, or a GP/hospital appointment or referral letter. If you are found to be eligible for a grant, the evidence will be requested and examined by an assessor when they visit your property.
Some individuals, who spend significant portion of their time at home, are considered to be at more risk during the cold winter months. This can include:
Alongside the health condition evidence detailed above, you can show your eligibility for the extra income threshold by providing a discretionary/disabled bus pass, blue badge, or by being registered with the local authority under section 18 of the Social Services and Well-being (Wales) Act 2014. This proof will be confirmed by the assessor when they visit your home.
As we have seen above homeowners and privately renting tenants can qualify for Nest energy efficient insulation. However, for privately rented homes, permission from the landlord will be required prior to any work being started. The process of getting landlord permission can be managed for you.
When a tenant applies for the scheme, landlords who give their approval for energy efficient improvements to be fitted need to sign a declaration form beforehand. The declaration puts in place a clause that the landlord cannot increase the rent on the property for at least 12 months after the installation has been completed.
You could be eligible for loft insulation grants in Wales through the Nest scheme if you meet the eligibility criteria above. Another option to get free loft insulation is via the Energy Company Obligation (ECO) scheme. This is a government-backed scheme that was launched in 2013 with the intention of lowering carbon emissions in domestic households across the UK as well as providing financial assistance to low-income homes who need support with their energy bills.
To qualify, your home should be owned or privately rented, currently occupied, and not going through any renovation, and if you are receiving an eligible benefit, you should be able to get a 100% grant that will fully cover the cost of installing loft insulation into your property. As well as this, there should be 100mm (4 inches) or less of insulation already in place in your loft. Normally, this will be in line with or below the joists, if it is over this level, you can get a survey and a quote to add it up to 270mm.
According to the Energy Saving Trust, a typical detached property adding 270m of loft insulation could experience annual energy bills savings of up to £380.
Any homeowners and private tenants that meet the terms of the eligibility criteria can get a free cavity wall insulation grant in Wales, as long as you are living in the home and there is no renovation work being done. Homes that are made of brick and constructed between 1924 and 1982 are generally suitable for cavity wall insulation. However, houses that were built up to 2005 without any insulation could also get help through funding.
As energy costs continue to rise and negatively impact homes across Wales, getting cavity wall insulation is one of the best things you can do to lower your heating bills and efficiently retain heat in your property. Studies have shown that an uninsulated cavity wall can lead to up to 35% of heat within a home escaping, and houses that have cavity wall insulation are able to save hundreds a year on their bills.
According to the Energy Saving Trust, a typical cavity wall installation could result in the following annual energy bill savings for different types of property:
