Is Buy-to-Let Still Worth It in the UK in 2026?

SYM

Buy-to-let property investment has faced significant headwinds since 2015: the removal of full mortgage interest relief (Section 24), the 3% stamp duty surcharge on additional properties, capital gains tax on disposal, and increasingly stringent EPC requirements. Meanwhile, mortgage rates have risen to 4–6%, compressing yields. The question for anyone considering or reviewing buy-to-let in 2026 is genuinely more complex than it was a decade ago — and the answer depends heavily on individual circumstances.

The Current State of Buy-to-Let Economics

A typical UK rental yield (annual rent ÷ property value) ranges from 4–7%, with higher yields in the North and Scotland and lower yields in London and South East. But gross yield is not the same as net return. Deduct: mortgage interest costs (at 4.5–5.5% on BTL mortgages), void periods (1–2 months/year is typical), maintenance (estimate 1% of property value annually), lettings management fees (10–15% of rent), landlord insurance, and Section 24 tax impact (mortgage interest is now a 20% credit, not a full deduction). For a higher-rate taxpayer on a leveraged BTL at 4.5% mortgage rate with a 5% gross yield, the after-tax net yield can be close to zero or negative — particularly on recently remortgaged properties.
  • •Gross yield: 4–7% depending on region
  • •BTL mortgage rates 2026: 4.5–6%
  • •Section 24: mortgage interest replaced by 20% credit — costly for higher-rate taxpayers
  • •After all costs: net yield often 1–3% for leveraged BTL
  • •Unencumbered (no mortgage) landlords: significantly better numbers

Section 24: The Tax Change That Changed Everything

Section 24 of the Finance Act 2015, fully implemented by 2020, removed the ability for individual landlords to deduct mortgage interest as an expense. Instead, a 20% basic-rate tax credit is applied. For higher-rate taxpayers, this significantly increases the effective tax on rental income. Example: £10,000 annual rent, £6,000 mortgage interest. Pre-Section 24: taxable profit = £4,000, 40% tax = £1,600. Post-Section 24: taxable profit = £10,000 (gross), 40% tax = £4,000, minus 20% credit on £6,000 = £1,200. Net tax = £2,800 — nearly double. This is why many higher-rate taxpayer landlords have either sold properties, transferred to limited company ownership, or become significantly less profitable.
  • •Pre-2020: mortgage interest fully deductible as expense
  • •Post-2020: 20% basic-rate tax credit only
  • •Higher-rate taxpayer impact: effective tax rate on rental profit dramatically higher
  • •Limited company: mortgage interest still fully deductible as business expense
  • •Unencumbered landlords: Section 24 doesn't affect them

Limited Company Buy-to-Let: Worth the Complexity?

Operating a buy-to-let through a limited company (Special Purpose Vehicle or SPV) allows mortgage interest to remain fully deductible as a business expense. Corporation tax (25% for companies with profits over £250k, 19% for smaller companies) applies to profits, rather than income tax at 40–45%. For a higher-rate taxpaying new landlord, the numbers often work better through a limited company. However, BTL mortgage rates for limited companies are typically 0.5–1% higher than individual rates, and accountancy costs (£1,000–2,000/year) add to the overhead. Transferring an existing property from personal to limited company ownership triggers Stamp Duty (3% surcharge), Capital Gains Tax on the transfer, and potentially SDLT — making retrospective incorporation expensive.
  • •Limited company: mortgage interest fully deductible, corporation tax applies
  • •Corporation tax: 19–25% vs. 40–45% income tax for higher earners
  • •Downside: higher BTL mortgage rates (0.5–1%), accountancy costs
  • •Transfer existing property: SDLT + CGT on transfer — expensive retrospectively
  • •Best for: new BTL investments, particularly for higher-rate taxpayers

Alternatives to BTL That Now Compete

A decade ago, BTL clearly outperformed alternatives like cash ISAs (near-zero rates) and even equity ISAs (lower returns and more volatility). In 2026, the comparison is closer. A global equity index fund in a Stocks and Shares ISA (no tax on gains or income, no management overhead, no mortgage risk, full liquidity) has historically returned 7–8%/year over the long term. REITs (Real Estate Investment Trusts, available inside ISAs) offer property exposure with full liquidity and no landlord responsibilities. For many people who would have bought a BTL a decade ago, the ISA route now offers comparable expected returns with far less complexity and tax. The emotional pull of property — tangible asset, rental income, capital appreciation — is real but should be weighed against the practical and tax realities.
  • •Stocks and Shares ISA: 7–8% historical return, tax-free, fully liquid, no management
  • •REITs: property exposure inside ISA, no landlord responsibilities
  • •BTL advantage: leverage amplifies returns (and losses), tangible asset
  • •BTL disadvantage: illiquid, high transaction costs, ongoing management
  • •Conclusion: both can work — BTL best for unencumbered or limited company investors

Frequently Asked Questions

Are landlords still making money in 2026?+

Yes — particularly unencumbered landlords (no mortgage) in high-yield areas, or those who have owned properties for many years and are on low fixed rates. Heavily leveraged landlords in low-yield areas are often struggling.

What are the EPC requirements for BTL landlords?+

Currently, rental properties must have a minimum EPC rating of E. The government has proposed raising this to C by 2030 — improvements could cost £5,000–15,000 for poorly rated properties. Factor this into the economics when buying.

Is now a good time to buy a BTL property?+

With mortgage rates elevated, buy-to-let works best when buying with significant cash (low leverage) or in a limited company structure with a good yield. The next 2–3 years may see rates fall, improving the economics — but timing the market is always uncertain.

Can I switch from personal ownership to a limited company?+

Yes, but it's expensive — SDLT on the transfer plus CGT means this is often not financially worthwhile for small portfolios. It's primarily beneficial for large portfolios with significant mortgage interest.
