The Short Answer: Yes, an Assessment Is Required
If
you are planning
External Wall Insulation in Ireland and want to access
SEAI grant support, a
Home Energy Assessment (HEA) is not optional — it
is required.
External Wall Insulation is treated as a major
fabric upgrade. Because it effectively wraps your home, SEAI rules
require it to be assessed and planned properly before any work begins.
At Churchfield Home Services, every
External Wall Insulation project
starts with this assessment step.
External Wall Insulation changes how heat and moisture move through your home.
If it is installed without proper planning, it can lead to issues such
as condensation, ventilation imbalance, or underperformance.
A
Home Energy Assessment ensures:
- External Wall Insulation is actually suitable for your home
- The correct insulation thickness and system are specified
- Ventilation and heating are considered alongside the insulation
- The upgrade meets SEAI technical requirements
This protects both your home and your investment.
External
Wall Insulation is supported through the Sustainable Energy Authority
of Ireland (SEAI)
One Stop Shop Home Energy Upgrade pathway.
Under this model, the
Home Energy Assessment:
- Is the first step in the process
- Determines which upgrades are appropriate
- Confirms how grants apply
- Sets out the correct order of works
As a Registered SEAI One Stop Shop, Churchfield Home Services manages this entire process for you.
During a Home Energy Assessment carried out through Churchfield Home Services, we look beyond surface-level details.
The
assessment reviews your home’s construction type, current insulation
levels, heat loss patterns, ventilation, and long-term upgrade
potential. This allows us to confirm whether External Wall Insulation —
often called a home “wrap” — is the right solution, or whether another
approach would deliver better results.
Can You Skip the Assessment and Still Get the Grant?
No.
External Wall Insulation is not a standalone grant, and SEAI grant
support is not available without a Home Energy Assessment.
Without the assessment:
- Grants cannot be approved
- Costs cannot be confirmed accurately
- The upgrade cannot proceed under the One Stop Shop
Any installer offering grant-supported External Wall Insulation without an assessment is not following the correct process.
What Happens After the Assessment?
Once your
Home Energy Assessment is complete, you receive:
- A clear explanation of whether External Wall Insulation is suitable
- Confirmation of which grants may apply
- A structured upgrade plan
- Clear next steps
There is no obligation to proceed with works. The assessment is about giving you clarity before making decisions.
