How the Autumn 2025 Budget Shapes the Next Phase of UK Property Investment

Chancellor Rachel Reeves delivered the Autumn 2025 Budget on 26 November, bringing the most substantial set of housing and property reforms we have seen in more than a decade. For months, speculation around a potential mansion tax, stricter landlord rules, and sweeping rental reform had caused hesitation across the market. Now that the details are confirmed, we have clarity at last, and with clarity comes opportunity.

From my perspective as an investor and as someone who works daily with landowners, developers, and institutional partners, this Budget marks a real turning point. Some changes will challenge parts of the market, but the overall direction supports long term stability, regional growth, and professional, compliant investment models.

Below is my breakdown of the announcements that matter and how they influence investor strategy going into 2026.

The myth of the new mansion tax, and what actually happened

The long rumoured annual proportional property tax for homes above five hundred thousand pounds has not materialised. That alone removes a major barrier to confidence, particularly given the volume of transactions and pipeline developments currently hovering in the higher mid market.

Instead, the Government has introduced a Council Tax High Value Supplement for homes worth two million pounds or more. The charge is set at two thousand five hundred pounds per year for properties above two million and seven thousand five hundred pounds for those above five million.

Only half a percent of UK homes fall into this bracket and around eighty five percent of these are in London and the South East. This further strengthens the case for investors who are already looking beyond the capital to regions with lower entry points and stronger demand fundamentals. For those investing in the North West for example, this Budget reinforces what we already know. Value, yield, demand, and capital growth potential remain concentrated in regional markets rather than prime London.

Income tax rises for landlords and investors

From April 2027, property income tax rates will rise by two percent across all bands. Dividend and savings income will also see the same increase. The new rates for property income will be:

Basic rate: 22 percent
Higher rate: 42 percent
Additional rate: 47 percent

For some landlords, this may accelerate decisions to exit the sector, particularly for those already operating with tight margins or older stock that requires compliance upgrades. However, reduced amateur landlord participation usually translates to less fragmented supply and more room for professional investors who understand structuring, tax efficiency, and portfolio strategy.

As rental demand continues to strengthen, fewer landlords simply means more opportunity for those who remain.

Build to Rent receives fresh support and new incentives

The Government has clearly identified Build to Rent as a core solution to national housing shortages. The Budget introduces:

• incentives for large scale rental developments
• green allowances to support EPC upgrades
• a new forty percent first year capital allowance for main rate expenditure
• increased funding for affordable rental supply delivered through public and private partnerships

This shift will speed up planning in priority regions, improve viability for developers, and create stronger long term stock for investors seeking stable, institutional grade assets. For groups already working in regeneration zones and large scale schemes, this direction of travel is exactly what the sector needed.

Capital Gains Tax adjusted to reward long term investors

Updates to CGT thresholds and relief structures are aimed at encouraging longer holding periods. This supports a more stable market and aligns with the way most sophisticated investors are already operating.

Put simply, the Budget now shows a clear preference for patient capital. Those who commit to holding assets rather than speculating in short cycles stand to benefit most.

Stronger incentives for energy efficient property

As expected, sustainability remains a priority. Landlords who upgrade EPC ratings will have access to grants and potentially preferential lending. For investors holding or developing stock, this will reduce long term running costs and widen tenant appeal.

Energy efficiency is no longer a compliance box to tick. It is a driver of valuation, demand, and operational cost savings. In the lodge, staycation, and leisure sectors this trend is even more pronounced.

Tourism taxes and the short term rental market

Regional mayors now have the ability to introduce an overnight levy similar to the visitor taxes used across Europe. Cities such as Liverpool have already adopted a two pound per night charge.

While some operators may see this as a small friction, the introduction of clear and consistent rules actually increases confidence in the sector. It formalises income expectations and legitimises short term rental models in high tourism cities such as Liverpool and Manchester. In areas where serviced accommodation underpins the visitor economy, this clarity will be welcome.

Inflation and interest rates: a calmer outlook for 2026

Budget measures are forecast to reduce inflation by zero point four percent. Inflation is expected to move towards two and a half percent in 2026, bringing it much closer to the Bank of England target.

Lower inflation creates conditions for future base rate reductions. This naturally feeds into more attractive mortgage products, improved affordability, and increased movement across both residential and investment markets.

What this Budget means for investors

The headlines changed, but the fundamentals have not. People still need places to live and stay. Cities still need regeneration. Demand still outstrips supply across the regions.

The Budget rewards investors who:

• focus on long term strategy rather than short term speculation
• operate professionally with compliant, high quality stock
• upgrade energy performance and future proof their assets
• diversify into growth regions where infrastructure and regeneration continue to strengthen value

The North West in particular remains one of the strongest markets in the country. Lower entry points, consistent demand, and ongoing regeneration projects continue to outperform London, which will be most affected by the High Value Supplement and continues to record annual price declines.

The divide between north and south is widening. For investors entering the market or looking to expand, Liverpool and Manchester remain among the most compelling locations for both yield and long term appreciation.

So, overall…

The Autumn 2025 Budget may have introduced new tax considerations, but it has also created a more structured and predictable environment for the next phase of property investment. Those who adapt quickly, understand the long term picture, and position themselves in the right regions will benefit most.

In times of regulatory change, experienced operators always come out stronger. Markets do not weaken under new rules, they reorganise. The advantage lies with those who are prepared.
