Two months ago, the biggest shake-up to the UK private rental sector in a generation quietly came into force. The Renters’ Rights Act, which took effect on 1 May 2026, abolished Section 21 “no-fault” evictions and converted virtually every assured shorthold tenancy in England into a periodic tenancy overnight. Some landlords panicked. Others sold up. But something else is happening beneath the headlines: for investors who have done their homework, buy-to-let is becoming measurably more attractive than it has been in years.
The average gross yield across UK buy-to-let property now sits at 7.2%, up from 7% across 2025 and significantly above the pre-pandemic average of 5.8% recorded in 2019. Rents are still rising, albeit more slowly than in the post-Covid frenzy. And with house prices growing at just 1.7% annually as of May 2026, the income story is increasingly where the real numbers are. Here is what is actually happening in the market right now.
The Renters’ Rights Act: What Changed and What It Means for Investors
The headline change under the new legislation is straightforward: landlords can no longer end a tenancy simply by serving a Section 21 notice. From 1 May 2026, possession requires a legally valid reason, and the grounds have been tightened. Rent arrears thresholds before possession proceedings can begin have been extended to three months, and notice periods doubled to four weeks. Landlords who had not issued the mandatory information sheet to tenants by 31 May faced fines of up to £7,000, with serious breaches carrying penalties of up to £40,000.
This is not insignificant. But experienced investors know that good tenants, properly managed properties, and well-chosen locations have always been the foundation of a successful portfolio. The Act has accelerated the exit of landlords who relied on high turnover or corner-cutting to make the numbers work. That consolidation is actually tightening supply in the private rental sector, which puts upward pressure on rents and strengthens the position of landlords with compliant, professionally managed stock.
At Aton Homes, the shift in the legislative landscape is something the team has been watching closely. The emphasis has always been on building resilient, income-producing portfolios rather than flipping for short-term capital gain, and that approach is looking increasingly well-suited to where the market is heading.
Rental Supply Is Still Critically Short
One of the most important numbers in the current market is this: there are roughly 25% fewer homes available to rent today than there were before the pandemic. New supply into the private rented sector has remained stubbornly low. The result is that even though tenant competition has eased from the extraordinary peak of 15.5 enquiries per property in 2022, the figure still stands at 5.6 enquiries per rental home as of May 2026. That is not a slack market. That is a market where quality rentals continue to find tenants quickly.
Average UK rents hit £1,381 per month in April 2026, representing 3.5% annual growth. The pace has slowed from the double-digit surges of recent years, but the direction of travel has not changed. Most analysts expect full-year 2026 rental growth to settle in the 2% to 3.5% range. For investors focused on yield rather than capital growth, that steady income picture, combined with rising yields, is a genuinely compelling backdrop.
The North of England Is Delivering the Strongest Yields in the Country
Not all buy-to-let opportunities are equal, and the regional picture in 2026 is sharper than ever. While London house prices continue to slide (down 2.1% between April 2025 and April 2026, from an average of £565,000 to £553,000), the North of England is producing yield figures that have caught serious investor attention.
Newcastle is currently recording the highest gross yields nationally at 9.7%, with Leeds close behind at 9.6%. Bradford offers average city-wide yields of around 7%, with certain postcodes reaching 10% to 11.6%. The North East as a whole is seeing rental growth between 6.5% and 7.6% annually, the fastest of any UK region, despite having some of the most accessible entry prices in the country. In a market where affordability constraints are squeezing buyers and driving sustained rental demand, those fundamentals add up.
The drivers behind this outperformance are familiar: lower entry prices mean more competitive yields, regeneration projects in cities like Leeds and Newcastle are expanding employment bases, and the tenant demographic in northern cities includes a growing student and young professional population with consistent rental needs.
Interest Rates, Mortgage Costs, and the Current Calculation
The Bank of England has held the base rate at 3.75% for four consecutive months, with inflation expected to edge back towards 4% later in 2026 as the energy price cap rises. For buy-to-let investors, this means mortgage costs are unlikely to fall sharply in the near term. The calculation has shifted: leveraged returns need more careful structuring than they did in the low-rate era, and lenders are continuing to stress-test at higher rates.
But this is also why the yield improvement matters. When house prices are growing slowly and gross yields are above 7%, the gap between financing costs and rental income is real. Investors who buy with strong rental demand in mind, rather than hoping for capital appreciation to do the heavy lifting, are finding that the income case for buy-to-let stands up on its own.
What Smart Investors Are Doing Now
Buy-to-let demand has not disappeared. It has shifted. The growth is coming from experienced investors who are reshaping existing portfolios and making targeted acquisitions in high-yield locations, often with a focus on HMOs (houses in multiple occupation) and multi-unit freehold blocks. Finance demand for these property types in Northern England and the Midlands rose 18% year-on-year in 2025. The profile of the active buy-to-let investor in 2026 is someone who treats property as a business, not a passive bet on rising prices.
The Renters’ Rights Act has changed some of the rules, but it has not changed the underlying logic of rental property as an investment class. It has, if anything, raised the floor on what constitutes a well-run investment. Properties that are compliant, professionally managed, and located in areas of genuine rental demand are proving their resilience.
