How it works
How rental yield works
Rental yield is the annual return on a buy-to-let property expressed as a percentage of the property's value. It is the most widely used metric for comparing investment properties and deciding whether a potential purchase stacks up financially.
There are two versions: gross yield (simple, before costs) and net yield (realistic, after costs). Most property listings and comparison sites quote gross yield because it is easier to calculate — but net yield is what you actually earn.
Gross yield formula: (Annual rent ÷ Property value) × 100. Example: property worth £200,000, monthly rent £1,000 (£12,000/year). Gross yield = (12,000 ÷ 200,000) × 100 = 6.0%.
Yield is only one part of the total return picture. Capital growth — the increase in the property's value over time — adds to (or subtracts from) your overall return. A 4% yielding property in a high-growth area may deliver a better total return than a 7% yielder in a stagnant market. See our mortgage affordability calculator to check whether the rental income covers the mortgage comfortably.
Gross yield vs net yield — why the difference matters
Gross yield tells you the income before you pay for anything. Net yield reflects what you actually keep after the inevitable costs of letting a property. The gap between them is typically 1.5–2.5 percentage points on an average UK property.
The main cost deductions for net yield are: void periods (time the property is empty), maintenance and repairs, letting agent fees, landlord insurance, and occasional costs like safety checks and advertising.
Average UK void period: approximately four weeks per year (roughly 7.7% of the year). On a £12,000/year rent, that is a £920 income loss. Maintenance and repairs average 1% of property value per year for a well-maintained property — £2,000 on a £200,000 home. Letting agent full management fees: typically 10–15% of monthly rent (£100–£150/month on £1,000 rent).
| Item | Annual amount | Impact on yield |
|---|---|---|
| Gross annual rent | £12,000 | 6.00% gross yield |
| Less: void periods (4 weeks) | −£923 | −0.46% |
| Less: maintenance (1% of value) | −£2,000 | −1.00% |
| Less: agent fees (12% of rent collected) | −£1,331 | −0.67% |
| Less: landlord insurance | −£250 | −0.13% |
| Less: safety checks (gas, electric, EPC) | −£200 | −0.10% |
| Net annual income | £7,296 | ~3.65% net yield |
Regional rental yield comparison across the UK
Rental yields vary enormously by region. The highest-yielding areas tend to be cities in the North and Midlands where property prices are lower but rental demand is high. The lowest yields are in prime London, where purchase prices are extremely high relative to achievable rents.
UK average gross yield stood at approximately 5.8% in 2026 (Zoopla Rental Market Report). The North-South divide in yields is stark: many northern cities offer 7–9% gross yields, while prime London boroughs average under 3%.
It is important not to chase yield at the expense of all other factors. Very high-yielding areas can also carry higher tenant turnover, greater maintenance costs, and more limited capital growth potential. A balanced portfolio typically includes a mix of yield-focused and growth-focused properties.
| Area | Avg gross yield | Avg property price | Avg monthly rent |
|---|---|---|---|
| Sunderland | ~9.2% | ~£130,000 | ~£1,000 |
| Hull | ~8.8% | ~£140,000 | ~£1,030 |
| Bradford | ~8.5% | ~£160,000 | ~£1,130 |
| Liverpool | ~8.0% | ~£175,000 | ~£1,170 |
| Manchester | ~7.0% | ~£240,000 | ~£1,400 |
| Leeds | ~6.5% | ~£230,000 | ~£1,250 |
| Birmingham | ~6.2% | ~£220,000 | ~£1,135 |
| Bristol | ~5.0% | ~£380,000 | ~£1,583 |
| London (Outer) | ~4.5% | ~£520,000 | ~£1,950 |
| London (Prime) | ~2.8% | ~£900,000 | ~£2,100 |
Yield vs capital growth — the investor's trade-off
The yield-versus-growth debate is central to buy-to-let investment strategy. High-yield properties generate strong ongoing income but often in areas with limited price growth. Low-yield properties (typically London) offer modest income but have historically delivered significant capital appreciation.
A simplified total return comparison: a 7% yielding property in Manchester growing at 3%/year delivers a total annual return of approximately 10%. A 3% yielding property in prime London growing at 6%/year also delivers 9% — similar returns, very different income-to-growth profile.
Your optimal strategy depends on your investment goals, tax position and financing. If you need cash flow now (e.g., the rental income must cover the mortgage and costs), prioritise yield. If you are building long-term wealth and do not need the income, capital growth markets may suit you better.
Note that gearing (using a mortgage to finance the purchase) amplifies both returns and losses. A 25% deposit leverages your return — but rising interest rates compress net yields significantly when mortgage costs increase.
Factors affecting total return beyond yield
- Capital growth rate in the local area (use Land Registry price paid data)
- Mortgage interest rate and LTV (affects net cash flow)
- Stamp Duty Land Tax surcharge (+5% on second homes in England/NI as of October 2024)
- Tenant demand and void risk (university cities and employment hubs lowest void risk)
- Rental regulation and licensing requirements (some councils require HMO licences)
- EPC rating requirements (minimum EPC C expected for new tenancies from 2028)
Tax on rental income — what landlords pay in 2026
Rental income is taxable as regular income in the UK. The tax you pay depends on your total income including rental profits, which are added to your other income and taxed at your marginal rate: 20% (basic rate), 40% (higher rate) or 45% (additional rate).
The £1,000 property income allowance lets individuals earn up to £1,000/year in rental income completely tax-free, without needing to declare it. This is most useful for occasional lets rather than professional landlords.
Crucially, landlords can no longer deduct mortgage interest from rental income directly (Section 24 rules, fully phased in since 2020). Instead, they receive a 20% tax credit on mortgage interest. For higher-rate taxpayers, this means an effective tax rate on the mortgage interest portion of 20% rather than full relief at 40% or 45%.
Example: landlord with £10,000 rental profit and £7,000 mortgage interest. Taxable rental income = £10,000 (not £3,000). A higher-rate taxpayer owes 40% on £10,000 = £4,000, minus 20% credit on £7,000 = £1,400. Net tax = £2,600. Under old rules: 40% on £3,000 = £1,200. The difference is significant.
Allowable expenses that can still be deducted include: letting agent fees, repairs and maintenance (not improvements), landlord insurance, safety certificates, accountancy fees, advertising costs and council tax paid during void periods.
Buy-to-let tax checklist for 2026
- Rental income taxed at marginal rate (20%, 40% or 45%)
- £1,000 property income allowance (declare nothing if gross rental ≤ £1,000)
- Mortgage interest: 20% tax credit only (not full deduction) — Section 24
- Stamp Duty surcharge: +5% above standard SDLT rates for second homes in England/NI
- Capital Gains Tax on disposal: 18% (basic rate) or 24% (higher rate) for residential property
- £3,000 annual CGT allowance (2026/27)
- Letting agent fees, repairs, insurance all deductible
- Consider incorporation if higher-rate taxpayer (company CT rate 25% but no S24 restriction)
Is buy-to-let still worth it in 2026?
Buy-to-let has become harder since 2017, with Section 24 tax changes, the stamp duty surcharge (now 5% in England), tighter lending rules and the phasing in of EPC C requirements for new tenancies. Many small landlords have exited the market.
However, the case for buy-to-let still holds in the right circumstances. Rental demand is very strong — record numbers of renters in 2026, limited social housing, and high house prices keeping many out of ownership. Average rents rose 7% year-on-year in 2025–26. A well-chosen property in a high-demand area with strong yield can still deliver solid total returns.
For higher-rate taxpayers, incorporation (buying through a limited company) has become increasingly attractive, as companies pay Corporation Tax at 25% and can deduct mortgage interest in full. However, setup and running costs, double taxation on withdrawal and complexity mean this is only worth considering for larger portfolios (typically 4+ properties).
The key question for any potential landlord in 2026 is: does the net yield exceed your mortgage rate? If your net yield is 4% and your mortgage rate is 5%, you are making a loss on income alone and relying entirely on capital growth to justify the investment.
