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.

Support and guidance documents

Domestic Technical Standards and Specifications (DTSS)

The DTSS details the technical requirements for the SEAI residential Programmes. A Contractor carrying out works for these Programmes must have the minimum levels of competency and commit to supplying materials and equipment and to perform the works to the defined requirements. The DTSS is based on S.R.54:2014 "Code of Practice for the Energy Efficient Retrofit of Dwellings".

Better Energy Homes Contractor's Code of Practice

The Better Energy Homes Code of Practice sets out the programme-specific requirements on contractors in carrying out works supported by the Programme.

Quality Assurance and Disciplinary Procedures (QADP)

The Quality Assurance and Disciplinary Procedures (QADP) document details the quality assurance procedures that are in place to govern the Better Energy programmes, including the reworks process. Here you will find a useful Inspector's checklist that will help you snag your own work.

Additional Information for Contractors

This document contains additional technical information that is not covered in the Code of Practice and QADP. It includes revisions to the SEAI programme standards that must also be adhered to in conjunction with the Code of Practice and QADP documents.

Desktop Audit Photographic Guidance

This document provides guidance on the photographic evidence required as part of a Desktop Audit to assist with the verification of the installation of works.


If you wish to appeal an Inspector's decision you must use this form. It is important to note that if you don't complete the works to the standards in the documents above, you will receive a request to complete reworks to bring the works to the specified SEAI standard.
