Autumn Budget 2025: Key announcements, changes, and what they mean for the property industry
Introduction:
After months of speculation and apprehension felt by the country, Chancellor Rachel Reeves has finally unveiled her much-anticipated second Budget. The announcement includes a wide range of measures affecting income and property taxes, cash ISAs, benefits, transport, and more.
The Budget has been positioned as a key step towards delivering the government’s promise of change, with a particular focus on reducing the cost of living, cutting the NHS waiting lists, and lowering debt and borrowing. Traditionally delivered twice a year, the Labour government has now committed to having just one Budget a year in late autumn and a Spring Fiscal Statement.
In this news article, we’ll cover everything you need to know in relation to property, with key insights and advice from our team of property specialists:
Key Takeaways:
- Homes worth more than £2 million will be subject to a ‘mansion tax’ from April 2028, impacting 0.5% of UK homes, with 85% of those in London and the South East.
- Landlords will pay an additional 2% of income tax on their rental income, putting additional pressure on the rental sector.
- No changes to stamp duty, which had been widely rumoured in recent months. However, the price bands for stamp duty were set a decade ago.
- The widely speculated property tax on homes over £500,000 has been avoided, potentially providing the market with a reboot of activity after months of hesitation.
High value council tax surcharge (“Mansion Tax”)
The Budget introduces a new surcharge on properties in England valued above £2 million, set to take effect from April 2028. This surcharge is structured progressively, with the initial band starting at £2,500 for homes in the £2-2.5 million region, rising to £7,500 for properties valued above £5 million. Expected to raise £400 million annually by 2031, this will apply to 0.5% of properties.
No changes to Stamp Duty Land Tax (SDLT)
Despite speculation in the run up to the Budget, there was no announcement of changes to SDLT, meaning rates for property purchases will remain as they were before. This means that for buyers, upfront transaction costs remain unchanged, but a lack of reductions may limit a boost in buyer demand.
No new annual tax on homes over £500,000
There was also speculation and media coverage that the government may replace Stamp Duty Land Tax (SDLT) with a national annual property tax, with some suggesting that this might apply from the £500,000 threshold. However, the government opted for a high value council tax surcharge instead.
Rental income tax increases for landlords
Most significantly landlords will face increased property tax rates from April 2027. The basic, higher and additional rates of income tax for property income will each increase by 2% taking them to 22%, 42% and 47% respectively, a change that will have a direct impact on profitability and long-term planning.
Our market impact predictions:
Industry bodies such as RICS report that the market has remained subdued throughout 2025, with buyer demand and sales activity largely flat and still in negative territory. Pre-Budget uncertainty has held back confidence, leading to weaker demand, slower sales, and limited new listings across most regions.
However, it is thought that the greater clarity provided by the latest Budget may help unlock activity and encourage more movement in the months ahead.
We spoke to Ian Harris, Residential Sales Customer Services Manager & President-Elect of NAEA Propertymark, to explore how this highly anticipated announcement will impact the property market – from residential and commercial property sales to surveys and valuations ahead of exchange.
Ian Harris, President Elect of NAEA Propertymark, comments:
“The property market withers uncertainty and thrives on confidence, so the end of the speculation about Capital Gains Tax, Inheritance Tax and Stamp Duty which remain unchanged is welcomed.
Interest rates have also given the UK property market some encouragement. Whilst the Bank of England base rate is unchanged, some of the UK’s major lenders have been cutting their rates to borrowers – an important move in the right direction. With the uncertainties of The Budget 2025 removed, the property market now has the prospect of stability in the short to medium term.
The introduction of a Mansion Tax in 2028 is still some way off, but those who are property-rich and cash-poor are already likely to be considering their position and the potential financial impact. The announcement is expected to have a particular influence on the London market, where the highest concentration of £2 million–plus properties is found, potentially shaping buying and selling decisions well before the tax is introduced.
The Lettings market remains positive, with demand from desirable tenants remaining strong. Moreover, due to limited supply, the national housing shortage is expected to keep rental demand strong going forward.
On the other hand, some landlords will be selling properties from their portfolios. Landlords’ profits are under pressure from higher taxes on property incoming and the Renters’ Rights Act 2025 becoming law. Often well looked after and mandatorily certified, these ex-rental properties can make great purchase opportunities for first time buyers and families. The often less than ideal presentation is an advantage for those looking to buy a solid house with opportunities to personalise and add value.
Improving affordability remains a key theme. House prices are broadly static at the moment, but the Office for Budget Responsibility (OBR) forecasts modest growth ahead, largely in line with earnings. Combined with the expected drop in mortgage rates as inflation continues to fall, this could help improve affordability for both first-time buyers and those looking to move up the ladder.
Across the market, much of the tension between buyers and sellers caused by uncertainty ahead of the Budget has begun to ease. As confidence improves, estate agents are reporting a lift in enquiries from both sides, along with more viewing activity and a noticeable increase in offers being made – even this close to Christmas. This renewed momentum is also beginning to filter through to surveys and valuations, with more transactions progressing and greater demand for pre-exchange assessments.”
We also spoke to Emily Ransome-Farmer MTPI AssocRICS, Head of Property Management, who commented on the impact these changes may have on landlords in particular:
“We know many landlords will be frustrated by yet another change to income tax, especially coming so soon after the higher stamp duty charge on additional homes and at a time when the Renters’ Rights Act and new energy rules are already creating extra work and cost.
We completely understand the pressure. Most landlords have already absorbed rising maintenance and mortgage costs for several years now, so this announcement will feel like one more hit to the bottom line.
That said, the rental market itself remains very strong. Rents have grown by around 25% over the last five years, and demand is still outstripping supply in most areas. For many landlords, that steady rise in rental income has helped balance out the increased overheads, and we’re continuing to see well-presented, sensibly priced homes let quickly and to good tenants.
The tax changes do mean it’s worth taking a fresh look at your figures and planning ahead, but there are still solid opportunities for landlords who stay on top of the market and keep their properties in good condition. We’ll be working closely with our clients to help them navigate the changes, stay compliant, and make sure their investments keep performing as well as possible.”
