Insulating your home can be an expensive prospect. Fortunately, SEAI grants can help with the cost of installing measures such as attic insulation or cavity wall insulation.

Insulation grants vary in value depending on the type of home and the specific project, such as attic insulation being worth more than cavity wall insulation, and detached houses getting more than apartments.

Home Insulation Grants

Grants Available for Home Insulation Ireland

The SEAI offers grants for many different types of home insulation including:

Home insulation grant values depend on the property type, insulation project, and the SEAI grants scheme.

types of home insulation

SEAI grants for home insulation are offered through three main streams:

  • Individual Energy Upgrades
  • One-Stop Shop
  • Fully-Funded Energy Upgrades

Individual Energy Upgrades

These grants, also known as the Better Energy Homes Scheme, allow homeowners more control over their retrofit projects by allowing them to choose individual renovations they intend to carry out on their property, whether it is cavity wall insulation or attic insulation, and apply for the grant for only that.

With the Individual Energy Upgrades, the applicant is responsible for the entire process including selecting a contractor and the grant application.

One Stop Shop

The One Stop Shop Service is aimed at homeowners who want to carry out a complete overhaul of their home to gain significant energy efficiency improvements.

This offers a wider array of insulation grants for home improvements than individual upgrades, with the entire process carried out by the chosen contractor.

Fully Funded Energy Upgrades

Also known as the Warmer Homes Scheme, this provides a range of energy efficiency improvements to homeowners who receive certain welfare payments. The grant completely pays for the improvements, and the SEAI handles all of the work.

The property must have been built and occupied before 2011, and must have an existing BER of B3 or lower. It must also be able to reach at least a B2 rating by having energy efficiency upgrades carried out.

To be eligible for the scheme you must be the owner and occupier of the home, which must have been built prior to 2006.

You must receive one of the following welfare payments:

  • Fuel Allowance
  • Jobseekers Allowance for more than 6 months, and have a child under 7.

How Home Insulation Grants Work

The application process for SEAI Insulation grants, and how to handle the construction and other paperwork, depends on what grants you are applying for, and through what scheme.

  1. Select which home insulation upgrades you wish to have carried out.
  2. Choose an SEAI-registered contractor. It is recommended that you shop around for multiple quotes.
  3. Apply for SEAI grants online, via post, or through a Better Energy Partner.
  4. Accept the grant offer. The offer must be accepted within 30 days of receiving grant approval for it it be valid. No work should be carried out before accepting the grant.
  5. Carry out home improvement work within 8 months of accepting the grant approval.
  6. Have a BER Assessment carried out on the property after construction.
  7. Submit grant payment request with Declaration of Works Form and BER Assessment.

Note: Payment of the grant can take 4 – 6 weeks after the payment request has been submitted.

One Stop Shop

To start the process a homeowner contacts a One Stop Shop from a list of SEAI registered providers. They will assess your home to determine if enough improvements are possible to qualify for the scheme and advise on what options are best suited.

Note: The SEAI has a separate €350 grant for a Home Energy Assessment.

They will manage the entire project from start to finish, including all of the construction work and follow-up paperwork.

With the One Stop Shop, the grant value is deducted from the upfront cost of the insulation or other home improvements. This means that homeowners know ahead of time exactly how much they will be paying.

Fully Funded Energy Upgrades

This programme covers the entire cost of upgrades such as attic insulation, new doors and windows, and more, for lower income homeowners on certain welfare payments.

The SEAI will then assess the property for appropriate upgrades, appoint a contractor to carry out the works, and after they are completed will carry out a follow up BER Assessment and quality inspection.

How to Apply

The application can be made online through the SEAI website, or by post, submitting the Application Form and Carers Allowance Confirmation Form if it applies, and posting them to:

Fully Funded Energy Upgrades
Sustainable Energy Authority of Ireland
PO BOX 119
Co. Kerry

Average Timeframe

  • Pre-works BER* – Approx 8 – 10 months from application
  • Survey – Approx 14 months from application
  • Works Completed – Approx. 24 – 26 months from application
  • Post works BER/Inspection – Approx. 2-3 months after works completed


In the vast majority of cases, you will not need planning permission to have insulation installed in your home. This may change if you live in a protected structure or area.

Attic insulation and cavity wall insulation are the simplest and most cost effective ways to make your home more energy efficient without causing a major disturbance.

If your insulation works affect more than 25% of the surface area of a home, there are energy efficiency requirements the project must meet.
