What Does External Wall Insulation Mean Under the One Stop Shop?


When External Wall Insulation is completed through the SEAI One Stop Shop, it is treated as part of a whole-home energy upgrade, not a standalone measure.

At Churchfield Home Services, this means External Wall Insulation is planned alongside other upgrades such as insulation, ventilation, and heating improvements. The goal is to ensure the home performs properly as a complete system, rather than improving one element in isolation.

Why External Wall Insulation Is a One Stop Shop Measure


External Wall Insulation has a major impact on how your home manages heat and moisture. Because it effectively wraps the outside of the building, it must be designed to work correctly with ventilation and heating systems.

SEAI requires External Wall Insulation to be delivered through the One Stop Shop so that:
  • The upgrade is properly assessed
  • Works are sequenced in the correct order
  • Long-term performance and comfort are protected

This approach reduces risk and ensures upgrades are carried out to the required standard.

Starting with a Home Energy Assessment


Every One Stop Shop upgrade begins with a Home Energy Assessment.

Through Churchfield Home Services, this assessment looks at how your home currently performs, where heat is being lost, and whether External Wall Insulation is suitable. It also confirms how the insulation should be combined with other upgrades to meet SEAI requirements.

This step ensures External Wall Insulation is recommended only when it makes sense for your home.

How Grants Work for External Wall Insulation


External Wall Insulation is supported by the Sustainable Energy Authority of Ireland (SEAI) under the One Stop Shop Home Energy Upgrade pathway.

Grant support for External Wall Insulation can be up to €8,000, depending on your home type and upgrade plan. As a Registered SEAI One Stop Shop, Churchfield Home Services applies for and manages the grant on your behalf.

Once approved, the grant is deducted upfront from the cost of works. You pay the net amount, with no waiting for reimbursement.

Which Homes Are Most Suited?


External Wall Insulation through the One Stop Shop is most commonly recommended for:
  • Older detached homes
  • Semi-detached homes
  • Properties with solid block or stone walls

Some homes may be better suited to other insulation measures first. This is why assessment and planning are essential before committing to External Wall Insulation.
