Stamp Duty Land Tax (SDLT) has always been a major consideration for anyone buying property in the UK, but in 2025, new changes to the stamp duty surcharge are set to impact first-time buyers in London in ways that may not be immediately obvious.
This guide explains what those changes are, who will be affected, and how to prepare, with expert insight from BES Accountancy, one of London's leading property tax accountancy firms.

What is the 2025 Stamp Duty Surcharge?
The UK government is introducing a revised stamp duty surcharge from April 2025, increasing the additional rate for certain property purchases from 3% to 5%. While this surcharge traditionally targets second-home buyers and overseas investors, many first-time buyers in London may find themselves indirectly affected due to rising property values and the removal or tightening of certain reliefs.

Why First-Time Buyers in London Need to Pay Attention
London property prices are among the highest in the UK. Although first-time buyer stamp duty relief remains in place up to a threshold, those purchasing above that limit may now face larger bills, especially if joint ownership or complex financing is involved. Many buyers assume that stamp duty relief automatically protects them, but changes in the surcharge structure mean:
Relief thresholds may not keep up with London property prices.
Some buyers may inadvertently lose eligibility for first-time buyer relief.
SDLT liabilities could increase unexpectedly depending on timing.
This means that first-time buyer stamp duty in London is no longer a straightforward calculation, especially as we approach April 2025.
The Hidden Impact of Timing: Why It Matters More Than Ever
One of the most overlooked aspects of the 2025 surcharge is how timing affects your liability. Buyers completing before the new surcharge date could save thousands, while those just weeks later could face significantly higher costs.
Consider this:
A £600,000 property purchase in London today might fall just within relief brackets.
From April 2025, if you're no longer eligible for relief or if joint ownership disqualifies you, your SDLT bill could jump substantially.
BES Accountancy recommends buyers planning to purchase in Q1 or Q2 of 2025 to review their timelines now.
BES Accountancy uses tools like Xero and QuickBooks to help clients prepare property tax forecasts, file returns, and avoid costly surprises.
How Stamp Duty Works for First-Time Buyers
Stamp duty relief for first-time buyers currently exempts properties up to £250,000 from any SDLT. For homes between £250,000 and £500,000, only the portion above £250,000 is taxed at 5%.
However, relief does not apply if:
You're buying with someone who is not a first-time buyer.
You're buying through a company.
You’ve previously inherited a property or owned one abroad.
With the stamp duty surcharge 2025 changes, these conditions will be more strictly assessed.
Examples of Unexpected Scenarios
Joint Ownership: A first-time buyer joins with a parent who owns property. The transaction becomes ineligible for relief, and the surcharge may apply.
Overseas Gifts: A buyer previously gifted a property abroad. HMRC may treat them as an existing homeowner.
Company Purchase: A business buying property for a director’s use will pay the full surcharge rate.
These real-world cases are why BES Accountancy urges caution and planning.
