Autumn Budget 2025

You will have seen it on the news, and read it on your socials, but here is a summary of the main changes announced by the Chancellor yesterday.

There have been no changes to Capital Gains Tax (CGT) or Inheritance Tax (IHT) rates, SDLT, or Principal Private Residence relief in the budget.

It was also announced that the Personal Allowance and tax thresholds will remain frozen for another three years. With rents continuing to rise, this will push more property investors into higher tax bands.

If you have any questions or need clarification of any of the above changes, please get in touch with your client manager at Calculated.

Mortgage & Investment Market Update

Post-Budget Summary for Landlords, Investors & Regional Markets

Iain Watts, our Senior Mortgage Advisor at Calculated makes the following observations:

The recent Budget delivered stability rather than surprise, and that has generally been welcomed across the landlord and property-investment space. While no major new measures were introduced to support or restrict the private rented sector, the government’s steady fiscal stance has contributed to calmer financial markets and slightly improved rate expectations. With inflation continuing to ease, lenders are gradually adjusting their pricing outlook, providing a more predictable environment for investors considering refinancing or portfolio expansion.

Buy-to-let lending conditions have also shown signs of improvement, with more competitive fixed-rate products and renewed appetite from specialist lenders. Although stress-test constraints still limit maximum borrowing in some cases, modest reductions in fixed rates have helped strengthen affordability metrics. For landlords refinancing from older low-rate mortgages, costs will still be higher, but the landscape is far less volatile than this time last year — aiding long-term planning and cash-flow forecasting.

Across the regions, market performance remains varied. Stronger rental demand continues to underpin yields in areas such as the North West, Midlands and well-connected commuter belts, making them attractive targets for yield-focused investors. Regions that experienced steeper price rises during the pandemic are now seeing gentler corrections, presenting opportunities for value-driven buyers. With no significant housing-market interventions in the Budget, these localised dynamics will continue to shape investment prospects more than national policy shifts.

Overall, the Budget reinforces a tone of cautious optimism. Stability in rates, resilient rental demand, and improving lender competition all help create a more navigable environment for landlords and investors. As the interest-rate cycle evolves over the coming months, reviewing refinancing opportunities and exploring regional yield potential may offer strategic advantages.
