A Real Estate Investment Trust (REIT) is a company that owns, operates, and finances income-producing property. UK REITs are listed on the London Stock Exchange. You buy shares through a standard brokerage account, just like buying shares in any other listed company.
Buy to let means buying a physical property, arranging a mortgage, finding tenants, managing the asset, and dealing with everything that goes with it.
Both give you exposure to UK property. They do it in very different ways.
REITs: how they work
UK REITs must distribute at least 90% of their rental profits as dividends each year. This makes them income-generating investments with a regulatory requirement to pay out most of their earnings.
Major UK-listed REITs include British Land, Land Securities, Segro, Unite Students, and Tritax Big Box. Each specialises in different property types: offices, retail, logistics, student accommodation, or residential.
You can buy REIT shares through any stockbroker or investment platform (Hargreaves Lansdown, AJ Bell, interactive investor, etc). Shares are bought and sold at market price during trading hours. There is no deposit, no mortgage application, and no solicitor.
REITs held within an ISA are completely tax-free on both dividends and capital gains. Within a SIPP, they benefit from pension tax relief.
BTL: what it offers
Direct property ownership gives you leverage. A 25% deposit controls 100% of the asset's value. If the property increases in value by 10%, your equity increases by 40% (10% of the full value divided by your 25% deposit). REITs do not offer this kind of leverage to individual investors.
You also control the asset. You decide when to refurbish, how much rent to charge, which tenants to accept, and when to sell. With a REIT, a fund manager makes these decisions.
BTL income is relatively predictable month to month (assuming the property is let). REIT share prices fluctuate daily, sometimes driven by stock market sentiment rather than underlying property values.
Comparing returns
| Factor | REIT | BTL |
|---|---|---|
| Typical income yield | 3% to 6% dividend | 4% to 8% gross rent |
| Capital growth | Tracks property market + market sentiment | Tracks local property market + value-add |
| Leverage | None (unless using margin, which is rare and risky) | 75% LTV standard |
| Liquidity | Sell in seconds | Sell in weeks to months |
| Tax efficiency | ISA/SIPP eligible | Not ISA/SIPP eligible, subject to income tax + CGT |
| Management effort | None | Significant (or pay 8-12% to an agent) |
| Diversification | One REIT may own 100+ properties | One BTL is one property |
| Minimum investment | Price of one share (£5 to £500) | £50,000+ (deposit + costs) |
The tax comparison
REIT dividends within an ISA: zero tax. REIT dividends outside an ISA: taxed at dividend tax rates (8.75% basic, 33.75% higher, 39.35% additional) after the £500 dividend allowance.
BTL rental income: taxed at your marginal income tax rate (20%, 40%, or 45%) after allowable expenses. Mortgage interest only receives a 20% tax credit (Section 24). CGT on sale: 18% (basic rate) or 24% (higher rate).
For a higher-rate taxpayer, the tax treatment of REITs within an ISA is dramatically more favourable than BTL.
Which is better?
Neither. They suit different investors.
Choose REITs if: you have less than £50,000 to invest, you want liquidity, you value diversification, you want zero management effort, or you want to invest within an ISA or SIPP.
Choose BTL if: you want to use leverage to amplify returns, you enjoy or are willing to manage property, you want to add value through refurbishment, or you want a tangible asset you control.
Many investors hold both. A BTL portfolio for leveraged income and capital growth, with REITs in an ISA for tax-free diversified exposure.
