In short: The “golden era” of 2015–2016, near-zero interest rates, full mortgage interest relief, no additional-property Stamp Duty surcharge, and light-touch regulation, is genuinely gone, and it isn’t coming back. But buy-to-let in 2026 isn’t dead: gross yields in many northern and midlands cities are still 6–8%+, mortgage rates have eased somewhat from the 2023 peak, and structural undersupply continues to support rents. It works less well as a “hands-off get rich slowly” play for highly-geared, higher-rate-taxpaying individual landlords in low-yield southern markets, and works better as a deliberate, numbers-led strategy, often through a limited company, in higher-yield locations, with realistic expectations about regulation and admin.
What’s genuinely changed since the 2015–2016 golden era
It’s worth being precise about what’s actually different, because landlord forums often lump everything into a vague sense of decline:
- Mortgage interest relief. Individual landlords in 2015–2016 could deduct 100% of mortgage interest before calculating taxable profit. Section 24, fully phased in since April 2020, restricts this to a 20% tax credit for individuals, a major, permanent hit for higher-rate taxpayers with significant mortgage debt (see our guide to renting in your own name vs a limited company for the full mechanics). This is arguably the single biggest structural change and the reason so many landlords are asking whether to incorporate.
- Stamp Duty surcharge. The 3% additional-property SDLT surcharge didn’t exist until April 2016 and has since risen to 5% (from the October 2024 Budget), plus companies buying residential property face the same 5% surcharge on top of standard rates. Buying in has simply become more expensive upfront than it was a decade ago.
- Mortgage rates. Base rate sat near 0.25–0.5% through most of 2015–2016, with buy-to-let fixed rates commonly available around 2–3%. After the 2022–2023 rate shock, buy-to-let mortgage rates rose sharply; by mid-2026 average two-year fixed buy-to-let rates sit roughly in the 5–6.5% range depending on loan-to-value and lender, meaningfully higher than a decade ago even after recent easing. This directly compresses net yield for anyone using significant leverage.
- Regulatory burden. 2015–2016 landlords didn’t have mandatory EICRs, the current EPC minimum standard, the Tenant Fees Act, or anything resembling the Renters’ Rights Act. In 2026, landlords must navigate the abolition of Section 21, new possession grounds, Section 13’s formal rent-increase process with tribunal challenge rights, expanding selective licensing, and (from later in 2026) registration with the new Private Rented Sector Database and Ombudsman. None of this is undoable, but it adds real compliance cost and risk of getting something wrong.
- Capital growth expectations. House price growth through 2015–2016 was often strong, particularly in London and the South East. By 2026, capital growth expectations are far more modest and regionally uneven, northern and midlands markets have generally outperformed London and the South East on both yield and recent price growth, a divide that has widened rather than narrowed since 2016.
What hasn’t changed, or has actually improved
- Structural undersupply. Total private rental stock remains meaningfully below pre-pandemic levels in most areas, and new housebuilding continues to lag household formation. This underpins rents even as growth has slowed.
- Rent growth has cooled to a sustainable pace, not collapsed. After 9%+ annual rent growth in 2022–2024, growth has settled to roughly 2–3% in 2026, closer to long-run, sustainable levels than the unusual post-pandemic spike, and still positive.
- Yields vary enormously by region, and some are strong. National averages mask a wide range: many properties in the North West, North East, Yorkshire, and parts of Scotland are achieving gross yields in the 6–8%+ range in 2026, while London and much of the South East and South West often sit closer to 3–4.5% gross once you account for high purchase prices relative to achievable rent. The “is BTL dead” framing usually comes from people benchmarking against low-yield southern markets; the picture looks very different in higher-yield regions.
- Limited company structures now largely neutralise Section 24 for new purchases, at the cost of higher SPV mortgage rates and more admin (see our guide to renting in your own name vs a limited company), this is a genuine, if imperfect, workaround that didn’t widely exist as a mainstream strategy in 2015–2016.
Running the numbers: what “working” looks like in 2026
A rough sense-check for a new purchase: – Take the property’s realistic achievable rent (verified against actual lets, not asking prices, see Q5) and calculate gross yield (annual rent ÷ purchase price). – Deduct mortgage interest at current buy-to-let rates, insurance, letting agent fees if used, an allowance for maintenance and voids (a common rule of thumb is budgeting 10–15% of gross rent for repairs, void periods and management combined), and any licensing costs. – Then apply your actual tax treatment, Section 24’s 20% credit if personal and higher-rate, or corporation tax if via a company, to see genuine net return. – Compare that net cash yield to what you could get from lower-effort alternatives (savings rates, index funds, other property alternatives) to judge whether the extra work and risk of being a landlord is being adequately compensated.
Properties bought with high leverage in low-yield areas, by higher-rate individual taxpayers, are the combination most likely to disappoint on this analysis. Properties bought with more equity (or through a suitably structured company), in higher-yield regions, by landlords who either self-manage competently or budget properly for an agent, are the combination most likely to still work well.
The honest verdict
Buy-to-let has moved from being a relatively passive, tax-efficient, highly-geared trade, the 2015–2016 playbook, to something that rewards a more deliberate approach: choosing higher-yield locations, being deliberate about ownership structure, budgeting properly for compliance and voids, and treating it as an active small business rather than a hands-off investment. Anyone comparing 2026 conditions to the golden era and concluding it’s automatically worse is only telling half the story, the other half is that yields in the right locations remain genuinely attractive, undersupply continues to support rents, and landlords who adapt their numbers and structure to the current rules are still making it work. It’s not that the window has closed; it’s that walking through it now takes more care than it used to.
