The supply of homes coming to market is now at its highest point in seven years, with an annual rise of over 4.2% for 2025 so far, according to figures from TwentyCi.
Data showed that new instructions in Q2 2025 increased by 5.6% compared with Q2 2024.
Sales agreed rose by 5.3% in the quarter and are up by more than 7% year to date compared with last year.
Exchanges in the second quarter dropped by 8.7% compared to Q2 2024.
However, residential transactions for 2025 so far are up 30% on 2024.
More than 3.2 million UK properties are now in the top 10% most likely to sell if they were to come to market in the next 12 months.
Online agents’ share of the market fell to 4.8%, with self-employed agents making up 2.3%.
eXp was the leading online or hybrid agent for new instructions in Q2, and became the largest brand in the country for new instructions in the period.
Colin Bradshaw, CEO at TwentyCi, said: “Q2 2025 is characterised by strong transactional activity across sales and lettings.
“Whilst the sales market is experiencing rising supply, there are persistent structural challenges in both the sales and rental sectors.
“While overall demand remains resilient, slower transaction timelines and rental affordability issues point to systemic issues that could dampen momentum if left unaddressed.”
Bradshaw added: “It is also the case that the recent Stamp Duty changes are still working their way through the system.
“This, in the short term, may lead to a cooling in buyer demand. Sellers may therefore need to adjust pricing expectations accordingly.
“In the medium to longer term, if inflation and interest rates stabilise, the market should rebalance, but affordability will remain a key constraint to activity and demand.”
