With changes to Stamp Duty Land Tax (SDLT) due to come into force in April 2025, a growing number of buyers are turning to property auctions as a faster and more certain route to securing a home.
According to NAVA Propertymark, auctions are no longer the preserve of professional investors hunting for distressed assets. Instead, they are attracting a broader mix of buyers, including owner-occupiers and first-time purchasers looking to beat higher tax bills and avoid the delays associated with traditional chains.
From 1 April 2025, SDLT thresholds will revert to lower levels, increasing the tax burden on many buyers. Properties priced above £125,000 will once again attract stamp duty, while the first-time buyer relief threshold will fall from £425,000 to £300,000. Industry figures warn that this change could add thousands of pounds to the cost of buying a home, particularly in higher-value regions.
Against this backdrop, auctions are gaining renewed appeal. Properties sold at auction are typically chain-free, removing one of the biggest causes of collapsed or delayed transactions. In unconditional, or traditional, auctions, contracts are exchanged as soon as the gavel falls, with completion usually taking place within 20 working days. This speed and certainty is proving attractive to buyers keen to complete before the new tax thresholds take effect.
The range of properties available at auction has also broadened significantly. While auctions were once associated mainly with refurbishment projects, today’s catalogues include everything from apartments and family homes to buy-to-let properties and development opportunities, often across a wide range of price points.
Digital auctions have further boosted accessibility, allowing buyers to bid online without attending a physical auction room. This has helped widen participation and increase competition, which can also benefit sellers seeking a decisive sale.
NAVA Propertymark’s latest Auctions Barometer for the second quarter of 2024 showed strong momentum in the sector, with 38% of agents reporting an increase in lot numbers. The trade body expects activity to remain robust into early 2025 as sellers look to transact before the stamp duty changes come into force.
Stuart Collar-Brown, president of NAVA Propertymark, said that although winter is traditionally a quieter period for auctions, recent Budget announcements have altered behaviour. He noted that the prospect of higher stamp duty costs may encourage more sellers to bring stock to market and more buyers to act decisively.
For buyers willing to do their homework and secure finance in advance, auctions can offer a strategic advantage. As the April 2025 deadline approaches, industry experts expect auctions to play an increasingly prominent role in helping buyers navigate a changing tax landscape while securing property quickly and with greater certainty.
