The average house price in Northern Ireland has increased since 2015, with minor fluctuations over time. The house price index is calculated using data on housing transactions and measures the development of house prices, with 2023 chosen as a base year when the index value was set to 100. In May 2025, the house price index reached 113.9, meaning that house prices have grown by nearly 14 percent since January 2023 and 9.5 percent since the same month a year ago. Among the different regions in the UK, the West and East Midlands experienced the strongest growth.
