Selling a Self-Build in Ireland — CGT Exemption, As-Built Plans, and What Buyers Want
On this page

Selling a self-build: CGT exempt if it's been your PPR. Have the as-built plans, BER, BCAR docs ready. Buyers want efficiency and quality.
Selling a self-build: CGT exempt if it's been your principal private residence (PPR). Have the as-built plans, BER certificate, BCAR documents (Commencement Notice, Certificate of Compliance, Assigned Certifier details) ready for the buyer. Buyers want efficiency and quality. An A1 BER, MVHR, heat pump, and a well-detailed build sell for 10–20% more than a basic build. Most Irish self-builds are sold through an estate agent. A premium build (BER A1, MVHR, heat pump) sells faster and for more than a standard build. The Daft Q1 2026 report shows new builds (including self-builds) sell for a premium over resales, especially with a high BER rating.
