Q2 2025 Online Auction Index 

We’ve hit another milestone in Q2 2025, as our Partner Agent network helped sell over 3,000 properties via online auction in a single quarter for the very first time. This record-breaking performance saw Capital Value raised hit £540 million – the highest ever total in our 15-year history and a 15% uplift on Q2 2024. 

With the dust now settled following the Stamp Duty deadline in April, some forecast a dip in demand – but the reality has been quite the opposite. Buyers and sellers alike are turning to auction as a faster, more secure alternative to Private Treaty, with our network of over 6,500 agents reaping the rewards. 

Hear more from our Co-Founder Jamie Cooke as he reflects on Q2’s standout achievements.

Q2, 2025 at Auction

Between April and June 2025, 3,130 properties were sold at auction – up 15% year-on-year and 9% on the previous quarter. Partner Agents earned a record £11.8 million in fees, highlighting the growing commercial opportunity auction offers. 

With over 15,000 bids placed and more than 56,000 viewings, auction continues to deliver strong performance at scale. The speed and certainty it brings have never been more relevant – especially as the average completion time for Private Treaty sales in the UK has now exceeded 200 days.

"Despite market-wide challenges like fluctuating mortgage offers and lower buyer activity, we’ve maintained steady momentum and delivered great results for our clients. Auction played a major part in a successful Q2 – helping us keep deals moving even when traditional routes slowed. It gave us a real advantage and kept our pipeline strong."

Aaron Tonks, Estate Agent at eXp UK and Director of Aaron Tonks – The Property Guy

"This was a record-breaking quarter. We saw our highest ever conversion rates from listings to sales, reflecting the strength of our partnership with iamproperty. Auction has helped maintain momentum, delivering strong results and a fast, secure, transparent route for sellers, even amid challenges like fluctuating mortgage offers and lower buyer activity, boosting trust, listings, and completions.”

Lisa Swain, Senior Branch Manager at Reeds Rains Wakefield

Consumer Viewpoint

Private Treaty timescales continue to worsen, with the national average now sitting at over 200 days from instruction to completion. Meanwhile, auction offers a significantly faster alternative – completing within 56-days on average.

Jamie's predictions for Q3

An overview of trends Jamie expects to see in the Auction market as we enter the first quarter of the year.
Pricing beats expectations

Optimistic house price growth

Although house price growth has largely flattened, prices are holding firmer than expected. We anticipate 2–4% annual growth depending on region, with accurate pricing key to successful sales – especially for higher-value homes. 

 

Market offers buyers choice

Healthier stock levels

Instructions are up, and auction appraisals are reaching record daily highs. With more choice in the market, correctly priced properties will continue to perform well in Q3. 

 

 

 

 

Record instructions and appraisals

Continued market confidence

Following April’s tax changes, many expected the market to stall – but that hasn’t happened. Instead, we’re seeing strong, stable growth. Auction is playing a crucial role in this, and early Q3 data shows further record-breaking momentum.
