Key Takeaways
- Badenoch announced the abolition pledge at the Conservative conference on 8 October 2025 in Manchester
- The plan covers primary residences only: buy-to-let and second homes would still pay stamp duty
- Estimated cost to the Treasury: £9 to £11 billion per year in lost tax revenue
- Conservatives launched a formal public petition approximately 3 weeks ago to build public pressure
- 40% of homes nationally are already stamp-duty-free for first-time buyers under current rules
- In London, only 11% of homes fall below the first-time buyer nil-rate threshold
- 800,000 homeowners have shelved moving plans due to stamp duty costs (Homeowners Alliance)
- Only 12% of buyers and sellers support keeping the current stamp duty system (OnTheMarket survey)
- The IFS describes stamp duty as one of the most economically damaging taxes in the UK system
The Conservative Pledge
On 8 October 2025, Conservative leader Kemi Badenoch announced at the party conference in Manchester that a future Conservative government would abolish stamp duty entirely on primary residences.
Badenoch called stamp duty a "bad tax that gums up the housing market" and said it penalises people for buying their home.
The pledge covers only main homes. Buy-to-let properties and second homes would continue to attract the standard rates plus the 5% additional dwelling surcharge.
Since then, the Conservative Party has launched a formal petition calling on the current Labour government to scrap stamp duty on main residences, gathering signatures over recent weeks.

What Abolition Would Cost
Fiscal Impact Estimates
- Conservative Party estimate: £9 billion per year in lost revenue
- Institute for Fiscal Studies estimate: £10.5 to £11 billion per year
- SDLT actually raised £11.6 billion in 2025 (a record year driven by pre-April rush)
SDLT raised £11.6bn in 2025, making it one of the largest property-related revenue sources for the Treasury.
The Conservatives argue that increased housing market activity and wider economic growth would partially offset the revenue loss. The IFS is more sceptical, noting the policy does not address the underlying supply constraints that drive prices.
To replace the revenue, the government would need to raise taxes elsewhere, restructure council tax, or introduce a new annual property levy.
Who Would Benefit Most?
The headline benefit looks dramatic, but the distribution is uneven. 40% of all homes nationally are already below the £125,000 nil-rate band (standard buyers) or the £300,000 nil-rate band (first-time buyers), meaning they pay little or no stamp duty already.
| Property Price | Current SDLT | Saving Under Abolition |
|---|---|---|
| £200,000 | £1,500 | £1,500 |
| £300,000 | £5,000 | £5,000 |
| £500,000 | £15,000 | £15,000 |
| £750,000 | £27,500 | £27,500 |
| £1,000,000 | £43,750 | £43,750 |
The higher the property price, the larger the absolute saving. 60% of all SDLT receipts come from properties in Southern England, so abolition would disproportionately benefit wealthier buyers in more expensive areas.

What Economists Say
Two perspectives dominate the debate.
The Savills Warning
Lucian Cook, head of residential research at Savills, warns: "If it is a simple tax giveaway, the likelihood is that the current stamp duty bill passes through into prices." This means sellers could capture the saving by raising asking prices, leaving buyers no better off.
The Institute for Fiscal Studies calls SDLT "one of the most economically damaging taxes" because it discourages people from moving to take new jobs or to downsize. Abolition would remove this distortion and could boost labour market mobility.
Cambridge University research found that abolishing stamp duty generates welfare gains of approximately 3.57%.
The tension: economists broadly agree SDLT is a bad tax, but many warn that a straight abolition without supply-side reform would inflate prices rather than improve affordability.
Public Opinion on Stamp Duty
An OnTheMarket survey found that only 12% of homebuyers and sellers want to keep the current stamp duty system unchanged.
Paula Higgins, chief executive of the Homeowners Alliance, has cited data showing 800,000 homeowners shelved moving plans in the past two years specifically because of stamp duty costs.
"Homeownership is the foundation of a fairer, more secure society. Stamp duty is one of the biggest barriers standing in the way."

Will It Actually Happen?
The Conservatives are currently in opposition and cannot implement this policy.
Labour has shown no appetite for abolition. The Spring Statement in March 2026 passed without any stamp duty changes, and the Autumn Budget 2025 also left rates untouched. See our coverage of the Spring Statement 2026: no reform announced.
Historical precedent is mixed: stamp duty holidays were introduced temporarily during COVID but then allowed to expire. Wholesale abolition represents a larger and more permanent fiscal commitment.
The most likely near-term scenario is targeted threshold reform rather than full abolition, with the Autumn Budget 2026 as the next realistic window for any significant change.
