Is Buy-to-Let Still Worth It in 2026? The Numbers Behind the Decision
The buy-to-let market has faced a relentless series of headwinds over the past decade — from the gradual erosion of mortgage interest tax relief to rising stamp duty surcharges, tighter lending criteria, and the highest mortgage rates in a generation. Yet landlords persist, and new investors continue to enter the market. So is buy-to-let still worth it in 2026, or are the numbers finally working against private landlords?
The honest answer is: it depends entirely on how you structure your investment, where you buy, and how carefully you stress-test your figures. Let's break it down properly.
Where Mortgage Rates Stand Right Now
After the dramatic rate rises of 2022 and 2023, the Bank of England began cutting its base rate through 2024 and into 2025. According to Bank of England data, the base rate has eased considerably from its 5.25% peak, providing some relief for variable-rate mortgage holders and pushing fixed-rate buy-to-let products lower.
However, buy-to-let mortgage rates remain notably higher than the sub-2% deals many landlords locked in during 2020 and 2021. As of early 2026, competitive five-year fixed buy-to-let rates from mainstream lenders are broadly sitting in the 4% to 5% range, depending on loan-to-value (LTV) ratio and whether you're borrowing personally or through a limited company. Use our LTV calculator to understand how your deposit size affects the rates available to you.
This matters enormously for viability. A landlord refinancing from a 2.5% fix onto a 4.5% product on a £200,000 interest-only mortgage sees their annual mortgage cost rise from £5,000 to £9,000 — a £333 per month swing that can turn a comfortable profit into a loss overnight.
Are Rental Yields Still Competitive?
Despite higher borrowing costs, rental yields have actually improved in many parts of the UK — largely because rising rents have outpaced house price growth in several regions. According to ONS private rental price data, average UK private rents rose significantly in 2023 and 2024, continuing upward pressure into 2025 as supply constraints persisted.
Gross rental yields — the annual rent as a percentage of the property purchase price — now look like this across key regions:
- North West (e.g. Manchester, Liverpool): Gross yields of 6%–8%+, representing some of the strongest returns in England
- Yorkshire and the Humber (e.g. Leeds, Sheffield): Gross yields typically 5.5%–7.5%
- West Midlands (e.g. Birmingham): Gross yields of 5%–7%, supported by strong rental demand
- Scotland (e.g. Glasgow, Dundee): Gross yields often exceeding 7%, though rent control legislation adds complexity
- London: Gross yields of 3.5%–5% in most areas — better than five years ago, but thin margins once costs are deducted
- South East commuter belt: Gross yields of 3.5%–5%, making cash flow challenging at current rates
Gross yield tells you relatively little. Net yield — after mortgage costs, letting agent fees (typically 10%–15% of rent), maintenance, insurance, void periods, and accountancy costs — is what actually determines whether your investment works. In many southern English markets, net yields for leveraged investors are dangerously thin in 2026.
The Tax Landscape: Why Structure Matters More Than Ever
Section 24, the phased removal of mortgage interest relief for individual landlords, is now fully embedded into the tax system. Individual landlords can no longer deduct mortgage interest as a business expense; instead, they receive only a 20% basic rate tax credit. For higher and additional rate taxpayers, this is a significant ongoing cost that fundamentally alters the investment case.
As reported by HM Revenue & Customs, landlords operating through limited companies are not subject to Section 24 restrictions — mortgage interest remains fully deductible against rental income for corporation tax purposes. With the corporation tax rate sitting at 25% for profits above £250,000 (and 19% for smaller companies under the small profits rate), the company route has become the default choice for most new landlords and those restructuring their portfolios.
Limited Company Buy-to-Let: The Pros and Cons
Operating through a Special Purpose Vehicle (SPV) limited company offers real advantages:
- Full mortgage interest deductibility against rental income
- Corporation tax rates (19%–25%) rather than personal income tax rates (up to 45%)
- Greater flexibility for profit retention and portfolio growth
- More favourable inheritance tax planning options in some scenarios
But the structure isn't without drawbacks:
- Limited company mortgage rates are typically 0.2%–0.5% higher than personal rates
- There are additional accountancy and filing costs (expect £500–£1,500+ annually)
- Extracting profits via dividends incurs personal tax on top of corporation tax
- Transferring personally-held properties into a company triggers stamp duty and potential capital gains tax
For new investors starting fresh, the limited company structure almost always makes mathematical sense if you're a higher rate taxpayer. For existing personal landlords, the decision to incorporate is genuinely complex — professional advice is essential.

Regional Hotspots: Where the Numbers Still Work in 2026
Location is arguably the single most important variable in determining whether a buy-to-let investment is viable right now. High-yield markets in the North and Midlands continue to attract investor interest precisely because the underlying numbers still produce positive cash flow even at current borrowing costs.
Cities to Watch
Manchester remains a perennial favourite — strong graduate retention, significant employment growth in the tech and media sectors, and rental demand that consistently outstrips supply in inner-city postcodes. Average gross yields of 6.5%–8% in areas like Salford, Hulme, and Ardwick make the sums workable.
Liverpool offers some of the highest gross yields in England, with certain postcodes delivering 8%–10%+ on the right property type. Regeneration areas around the city centre and Baltic Triangle have attracted sustained investor interest.
Birmingham benefited from significant infrastructure investment and has a large, young renter population. HS2 delays have dampened some enthusiasm, but underlying rental demand remains robust.
Leeds and Sheffield both offer a combination of large student populations and growing professional rental markets, supporting consistent yields above 6% in well-chosen locations.
In contrast, prime London and much of the South East remain extremely difficult markets for leveraged buy-to-let investors to generate positive cash flow in 2026, particularly on new purchases. Capital growth remains the primary investment thesis in these markets — a legitimate strategy, but a different risk profile entirely.
The Bigger Picture: Is the Hassle Factor Worth It?
Beyond the pure numbers, it's worth acknowledging that the regulatory environment for landlords has tightened considerably. The Renters' Rights Act, progressing through Parliament and expected to receive Royal Assent in 2025, abolishes Section 21 "no-fault" evictions and introduces sweeping changes to tenancy law. Landlords face greater obligations around property standards, and the notice periods required to reclaim properties are extending.
This doesn't make buy-to-let unviable — but it does raise the bar for what constitutes a well-managed investment. Landlords who treat property as a passive income stream without professional management support are increasingly exposed to regulatory risk.
"The days of easy, hands-off buy-to-let are behind us. The investors thriving in 2026 are those who treat it as a business — with the right structure, the right advisers, and a genuine understanding of their local market."
So Is Buy-to-Let Worth It in 2026?
For the right investor, in the right location, with the right structure — yes, absolutely. Buy-to-let can still generate meaningful returns and long-term wealth accumulation. Gross yields of 6%–8% in northern English cities, when combined with a limited company structure and careful tax planning, can deliver positive cash flow and genuine return on equity even at 2026 mortgage rates.
For investors relying on low-yield southern markets, hoping for capital growth alone, or borrowing on a personal basis as a higher-rate taxpayer without accounting for Section 24 — the numbers are genuinely difficult to make work, and the risks have risen materially.
The key is doing the analysis rigorously before you commit. Speak to a specialist buy-to-let mortgage broker, model both company and personal structures, stress-test your yield assumptions against realistic voids and costs, and be honest about whether the investment genuinely meets your financial goals.
