Buy-to-Let in 2026: Why Smart Investors Are Still Expanding Their Portfolios

With tax changes, rising costs, and regulatory shifts dominating the headlines, it would be easy to assume that buy-to-let is in retreat. The data tells a very different story. Rental yields have hit a record high of 6.6%, 89% of landlords reported turning a profit in 2025 — the highest proportion since 2019 — and limited company structures are now the dominant vehicle for new BTL purchases. For investors who understand the landscape, 2026 is shaping up to be one of the most strategic entry points in years.

The Numbers Behind the Headlines

Despite years of predictions that landlords would exit the market en masse, the fundamentals remain strong. Rental demand continues to outstrip supply across most of the UK, particularly in the North and Midlands, as rising house prices keep more people in the rental sector for longer. Average gross rental yields across England and Wales sit at around 5 to 6%, with Northern cities delivering more. Net yields, once costs are accounted for, typically land in the 3 to 4.5% range — still comfortably ahead of savings accounts and comparable to gilt yields, with the added benefit of capital growth potential.

Savills forecasts that UK rental values will grow by around 12% over the next five years, with London close behind at 11.5%. For income-focused investors, this sustained upward pressure on rents is a core part of the investment case.

Limited Companies: Now the Preferred Structure

One of the most significant shifts in the BTL market is the move towards limited company ownership. According to Paragon Bank, limited companies accounted for 43% of all mortgaged buy-to-let purchases in 2025 — up from 35% the year before and just 7.5% back in 2018. Over 400,000 BTL limited companies are now registered in the UK, making it the single biggest business type in the country.

The driver is straightforward: since the Section 24 mortgage interest relief changes came into force, holding property personally means being taxed on gross rental income with only a 20% tax credit on mortgage interest. Holding property within a limited company allows mortgage interest to be fully deducted as a business expense, significantly improving net returns, especially for higher-rate taxpayers.

For investors planning to build a portfolio of two or more properties, speaking to a specialist mortgage broker about limited company BTL mortgages is now essentially essential. Rates on limited company products have become increasingly competitive, with many now available below 5%.

Where Are the Best Opportunities in 2026?

Geography matters more than ever. London still commands premium prices per square metre, but yield compression makes it harder to generate strong cash flow from new acquisitions. The real opportunity lies in regional cities where entry prices are lower, rental demand is rising, and regeneration is driving capital growth.

Manchester topped the list for the fastest-growing buy-to-let area in 2025, with Liverpool, Leicester, Leeds, and Birmingham also ranking highly. The North West, Midlands, and Yorkshire are projected to outperform the national average for both rental growth and capital appreciation, driven by infrastructure investment, expanding employment hubs, and improving transport connectivity.

HMOs (Houses in Multiple Occupation) are also attracting growing attention, as the higher rental income per property can significantly improve yields compared to standard single-let investments.

Navigating the Regulatory Changes

The Renters' Rights Act received Royal Assent in October 2025, with the first changes expected to come into force on 1 May 2026. The most significant of these include the end of Section 21 no-fault evictions, the introduction of rolling tenancies to replace fixed-term contracts, and the removal of blanket no-pets and no-DSS policies.

While these changes require professional landlords to adapt their processes, they do not fundamentally alter the investment case for well-managed properties. Investors who treat buy-to-let as a business — with proper documentation, responsive management, and up-to-date compliance — will navigate these changes comfortably. Those operating informally may find the new environment more challenging.

The Mortgage Landscape for BTL Investors

Buy-to-let mortgage rates remain higher than their pre-2022 levels, but the direction of travel is improving. The Bank of England base rate sits at 3.75%, with further cuts anticipated during 2026. Lenders are actively competing for BTL business, with product innovation accelerating — particularly for limited company structures and portfolio landlords.

For investors remortgaging existing BTL properties this year, the picture varies. Some will benefit from lower rates compared to their previous deal; others coming off pandemic-era fixes will see costs rise. Either way, speaking to a specialist broker well ahead of your deal expiry is critical to securing the best available terms.

Is Buy-to-Let Right for You in 2026?

The answer depends on your goals, tax position, financing structure, and choice of location. For those willing to approach it strategically — with the right mortgage structure, the right property type, and the right location — buy-to-let continues to offer a compelling combination of income, capital growth, and inflation protection that few other asset classes can match.
