Should I Buy a UK Buy-to-Let in 2026?

What three tests decide whether a buy-to-let works in 2026?

Gross yield after realistic voids, debt service at a stressed rate, and a credible exit within five to seven years. If any one fails, the case is weak regardless of the postcode.

Every buy-to-let we review comes down to the same three tests. If any one of them fails, the case is weak regardless of the postcode.

• Does gross yield clear 6.5% after realistic voids and management?
• Does the property still service debt at a stressed mortgage rate of 7%?
• Is there a credible exit inside 5–7 years without a forced sale?

Where does the maths typically break in 2026?

Section 24 pushed higher-rate landlords into an effective yield haircut of 200–300 basis points. Combined with 5%+ stress rates, a nominal 6% yield often turns net-negative once management, voids and repairs are honest.

Section 24 mortgage interest restriction now applies fully to individual landlords. A higher-rate taxpayer can no longer deduct finance costs; instead they receive a 20% tax credit. The effect is that a gross 6% yield can fall to a net 2.5–3% after tax for a leveraged investor. Add voids, repairs, management and compliance, and the trade only survives where the gross yield is meaningfully higher or the buyer is not leveraged.

When does the trade still make sense?

For cash buyers, lower-rate taxpayers, corporate structures with genuine operating substance, and investors targeting a specific micro-market they know well. It is no longer a default asset for higher-rate taxpayers in personal name.

The trade still works for cash buyers, corporate structures with legitimate operating substance, and investors targeting HMO or serviced accommodation in a specific micro-market they know well.
