Autumn Budget 2025 – What It Means for Buyers, Sellers, Landlords & Renters
Today’s Autumn Budget, delivered by Chancellor Rachel Reeves, introduced several major changes that will affect the UK property market over the coming years. Here’s our quick breakdown of what you need to know:
For Homeowners & Sellers
High-Value Property Surcharge (from April 2028)
A new annual “mansion tax” will apply to homes in England valued at £2 million+ (based on 2026 prices).
• £2,500 per year for properties £2m–£2.5m
• Up to £7,500 for properties £5m+
This may encourage some owners of high-value homes to bring plans forward or reassess long-term costs.
Homebuying Process Reforms
The government aims to make buying and selling quicker and less stressful, with proposals including:
• More upfront information provided by sellers
• Binding contracts to reduce fall-throughs
• Higher standards for estate and letting agents
• Digital property logbooks to securely share information
These changes should help improve transparency and reduce delays.
For Landlords
Several measures will increase the cost of property ownership:
Income Tax Increase (from April 2027)
The basic, higher and additional rates of income tax on property and savings income will rise by 2 percentage points.
National Insurance on Rental Profits
Landlords will now pay 8% National Insurance on their rental income, similar to the self-employed.
This is expected to push some landlords to review their portfolios.
Inheritance Tax (IHT) Reform
The value of tax-free lifetime gifts is likely to be capped, and taper relief could shorten. Landlords planning long-term succession should monitor these changes closely.
For Buyers
Stamp Duty
No new changes to SDLT today — rates remain as adjusted in April 2025.
However, the government is exploring bigger structural reforms, including potentially replacing Stamp Duty or shifting liability to sellers. No immediate changes.
The proposed improvements to the buying process (more upfront information, digital logbooks, binding contracts) should ultimately make moving home smoother and more secure.
What This Means for the Property Market
The increased tax burden on property income and high-value homes may lead to:
• More landlords choosing to sell
• Some high-value homeowners reviewing long-term costs
• Increased movement in certain parts of the market
Estate agents will play a growing role in advising clients on the financial considerations of buying, selling or renting under the new rules.
