Understanding Rental Yields in the UK (2026)
I know a guy who bought a Manchester buy-to-let because the listing said "6% yield." He was chuffed. Thought he'd cracked it. Then the letting agent took their 10% cut. Then the boiler needed fixing. Then a tenant moved out and the flat sat empty for 6 weeks. Then he had to repaint. His actual return? 2.8%. The difference between the marketing number and reality cost him about £3,500 per year in unrealised income.
That's the buy-to-let game in a nutshell: everyone quotes you gross yield and hopes you don't ask about the costs. Because once you factor in the actual costs of owning a rental property, suddenly that "amazing 6% opportunity" becomes a mediocre 3% that you're doing admin work for.
Here's what I want you to understand before we go any further: there are two yield numbers. One is marketing bullshit. One is real. Most people only hear about the first one and wonder why they're not making money.
Gross Yield: The Number Everyone Lies With
Gross yield = (Annual Rent ÷ Property Price) × 100. On a £250k property rented at £1,100/month, that's 5.28% gross yield. Looks great. Sounds great. Is completely meaningless for actual decision-making.
Why? Because it ignores literally every cost of owning the property. It's like saying "if I drive my car and pay for petrol but ignore maintenance, insurance, repairs, and tax, my cost per mile is amazing!"
Net Yield: The Number That Actually Tells You If You'll Make Money
This is where fantasy meets reality. Net yield = ((Annual Rent - Annual Costs) ÷ Property Price) × 100.
That £250k property rented at £1,100/month? Here's what it actually costs to own:
- Lettings agent (10% of rent): £1,320
- Maintenance & repairs (1% of value): £2,500
- Buildings insurance: £500
- Void periods (2 weeks/year): £550
- Landlord services/inspections: £300
- Total annual costs: £5,170
Net yield = ((£13,200 - £5,170) ÷ £250,000) × 100 = 3.21% net yield.

Section 24: The Tax Change That Killed Small Landlord Profitability
Section 24 fundamentally broke the economics of small buy-to-let portfolios for higher earners. Before April 2017, you could deduct mortgage interest from rental income before calculating tax. Now, you get a flat 20% tax credit only — meaning higher-rate taxpayers pay the difference.
Real example: You earn £70,000/year (40% tax bracket) and own a buy-to-let generating £12,000 annual rent with £8,000 mortgage interest.
- Pre-2017: You'd pay tax on £4,000 (£12k rent minus £8k interest). At 40%, that's £1,600 tax. Mortgage is "deducted" from your rental income.
- Post-2017 (current): You pay tax on the full £12,000 at 40% = £4,800. You get a 20% credit on the £8,000 interest = £1,600. Your net tax bill is £3,200. You've doubled your tax liability.
This change has caused thousands of small landlords to sell up. If you're a higher-rate taxpayer considering buy-to-let, you need to factor in this £1,600/year additional tax on the example above. It eats 12% of gross rental income.
Key Costs to Include in Your Yield Calculation
- Maintenance & repairs: Budget 1–2% of property value per year (or 10% of annual rent)
- Landlord insurance: £200–£600/year for buildings + landlord liability
- Letting agent fees: 8–15% of monthly rent if using an agent (tenant-find only is cheaper at 50–100% of one month's rent)
- Void periods: Factor in 2–4 weeks per year between tenancies
- Service charges: £1,000–£5,000+/year for leasehold flats
- Gas safety certificate: £60–£90/year (legally required)
- EPC certificate: £60–£120 every 10 years
- Selective licensing: £500–£1,000 every 5 years (area-dependent)
