As part of the Government’s Carbon Emissions Reduction Target (CERT), grants ranging from 50% to 100% are offered to help cover the cost of having cavity wall insulation.
Any property in the UK is eligible for a grant, but the amount depends on the type and the size of the home. Not all properties qualify for full free insulation grants, but they will be eligible for partial insulation grants between 50% and 70%.
Criteria
There are certain criteria which determine if you do qualify for a grant to cover the full cost of the cavity wall insulation.
If you receive Attendance Allowance, a tax-free benefit for over 65’s who need someone to help look after them because they are physically or mentally disabled, or you receive Child Tax Credit and earn an annual income of £15,460 or less then you’re automatically eligible for a full grant.
The same goes for anyone who receives Council Tax Credit, Housing Benefit and Income Support, however all of these must include a disability premium.
Anyone receiving Disability Living Allowance and Disability pension also qualify along with those who claim for War Disablement Pension and Industrial Injuries Disablement Benefits, but both need to include a mobility supplement or Constant Attendance Allowance.
You’re also eligible if you receive Income-based Job Seekers Allowance, State Pension Credit or Working Family Tax Credit for those with an annual income of £15,460 or less.
