External Wall Insulation Grants for Detached and Semi-Detached Homes

Why a Home Energy Assessment Comes First

Before any grant or cost can be confirmed, a Home Energy Assessment is required.

Through Churchfield Home Services, the assessment looks at how your home currently performs, how much heat is being lost through the walls, and whether External Wall Insulation is the right solution. It also confirms how the insulation should be sequenced with other upgrades such as ventilation or heating improvements.

This ensures External Wall Insulation is only recommended when it will work properly for your home.

Detached vs Semi-Detached: What’s the Difference?

Detached homes usually have the greatest amount of exposed wall area, which means they often benefit most from External Wall Insulation — but they can also involve higher overall costs due to scale and access requirements.

Semi-detached homes may still be well suited, particularly where one or more external walls are uninsulated. However, suitability depends on layout, construction type, and existing insulation levels, which is why assessment matters more than house type alone.

How Churchfield Home Services Manages the Process

As a Registered SEAI One Stop Shop, Churchfield Home Services manages the entire journey for detached and semi-detached homeowners, including:

• Home Energy Assessment
  
• Upgrade design and sequencing
  
• SEAI grant application and approval
• Installation and project coordination

Once approved, the grant is deducted upfront from the cost of works, so you only pay the net amount.
