A savings target of £17,000 has become the benchmark for first-time buyers seeking a 5% deposit on a standard £340,000 starter home in late 2026. While the median deposit across the UK has risen to approximately 14.4% this year, a series of new government measures and high-yield savings accounts have created a specific roadmap for those looking to enter the market with a smaller upfront sum.
On September 26, 2026, the government announced the “Your First Home” scheme, which significantly lowers the entry threshold for those purchasing new-build properties. The initiative allows eligible buyers to secure a home with a 2.5% deposit, supported by a 20% government equity loan. Under this scheme, a £17,000 deposit could potentially facilitate the purchase of a property valued up to £680,000. Alternatively, a buyer could secure a £340,000 home with an upfront payment of just £8,500.
Maximising the 2026/27 Lifetime ISA
For those targeting a 2026 or 2027 purchase, the Lifetime ISA (LISA) remains a primary vehicle for deposit growth. For the 2026/27 tax year, the annual contribution limit remains at £4,000. By reaching this cap, savers receive a 25% government bonus of £1,000 each year. Although the government plans to replace the LISA with a dedicated First Time Buyer ISA in April 2028, the current scheme remains the standard tool for those currently saving for a deposit.
Utilising high-interest regular savings accounts can further accelerate the timeline to reach £17,000. As of late September 2026, top-tier regular savings rates have reached 8% variable at Santander, while First Direct is offering 7% fixed. By combining a fully funded LISA with an 8% regular saver, a buyer contributing approximately £400 per month can reach the £17,000 threshold in roughly three years, factoring in accumulated interest and the annual government bonuses.
Alternative Paths to Ownership
For buyers unable to reach the full £17,000 for a traditional mortgage, Shared Ownership offers a lower-cost entry point. In 2026, the scheme continues to allow for the purchase of shares as low as 10% of a property’s total value. In these cases, the required deposit is typically calculated as 5% to 10% of the share being purchased rather than the full market value, often requiring substantially less than the £17,000 benchmark for a 5% deposit on a freehold home.
While the £17,000 figure represents the lower end of current market deposits—specifically the 5% entry-level threshold for a £340,000 property—financial analysis suggests it remains a viable target for those utilizing the newest high-leverage schemes. While the median deposit is currently closer to £36,000 for many UK regions, the 2.5% “Your First Home” scheme and existing 5% mortgage products provide specific routes for those with smaller capital reserves.
