Principality Building Society has published its Wales House Price Index for Q2 2025 (April – June) and reported a “modest increase” from the same period last year.
The average price of a home sold in Wales in the second quarter of 2025 was £238,098, compared to £236,369 in the same period in 2024, equating to 0.7%. The data covers the rise and fall in house prices in each of the 22 local authorities in Wales.
Torfaen leads the way, with by far the highest quarterly price change of any authority (14%). This is followed by Carmarthen, with a 6.3% quarterly increase, and Flintshire, up 3.3% for that period.
Gwynedd has seen a quarterly decline in prices of 7.3%, when Principality’s report suggests is possibly “in response to recent policy changes, such as the Welsh government’s adjustments to second home taxation, in addition to the potential impact of Gwynedd Council’s Article 4 Direction, which requires planning permission to be secured before changing the use of a property into a second home, short-term holiday let or specific mixed use.”
HM Land Registry data shows there were over 10,000 property transactions in Wales during the second quarter of 2025, a 13% rise compared to the same period last year, reflecting a trend in year-on-year recovery in property sales.
Iain Mansfield, chief financial officer at Principality Building Society, said: “The housing market in Wales continued to stabilise in the second quarter of 2025, with prices holding broadly flat compared to the start of the year. Encouragingly, the steady increase in transaction volumes signals increasing confidence among buyers.
“While market conditions remain challenging, a downward trend in mortgage rates is helping to create a more favourable environment for buyers. This shift is contributing to a gradual uplift in consumer confidence as we move into the second half of 2025.”
