Use these guidance documents to ensure the works you carry out under the Better Energy Homes scheme meet the required SEAI Standards.

Quality of service

The quality of service delivery is central to the reputation and effectiveness of all home energy efficient works supported by SEAI. We have put together a number of supports and guidance documents that will help you complete your work to the required standard. Following these guidelines will benefit your reputation and help grow your business.

Part of your role is to support the Homeowner in making the right decisions in upgrading their home. This includes explaining and agreeing the proposed works, providing a quote for works and agreeing a contract between Homeowner and Contractor.

Please note, registered Contractors can offer the Homeowner the cost of works net of the grant amount. To do this, the Contractor can ask the Homeowner to nominate the Contractor's preferred bank account with bank details on the SEAI Request for Payment form.

Quality Management Systems

All contractors working on SEAI programmes are required to have a Quality Management System in place.

An effective Quality Management System will help contractors manage grant works from start to finish resulting in faster payments, better compliance, a reduction in the costs associated with remedial works and higher levels of customer satisfaction.

SEAI regularly holds in-depth webinars on the fundamentals of Quality Management Systems. The webinar briefs contractors on:

  • General quality management frameworks
  • Management of grant installations
  • Quality assurance checks
  • Documentation requirements
  • Quality management tools and templates

Below you will find some useful quality management resources including a copy of the webinar recording and presentation, along with a quality management template. It is highly recommended that all nominated personnel, your quality manager and any staff involved in processing grant-related works familiarise themselves with these resources.
