Westminster Buy-to-Let Yields 1.9%, Holiday Lets Trail at 0.9%

Both revenue figures match the Dashboard's calculation for this market.

Buy-to-let grosses around £62,000 a year against holiday let's about £30,000, with the 90-night cap doing most of the damage to the holiday let case. Operating costs widen the gap further.

The 90-Night Cap Caps Holiday Let Revenue at about £39,000

Westminster sits inside Greater London, where the Deregulation Act 2015 limits short-term letting to 90 nights per year without planning permission. That ceiling, not occupancy or pricing, is the binding constraint on holiday let economics here. Even at 100% occupancy across every permitted night, gross revenue tops out at roughly £39,000, well short of buy-to-let's about £62,000.

Holiday let in Westminster only matches buy-to-let income when occupancy crosses 160%, a number above 100% because the 90-night ceiling is too low for the holiday let model to catch buy-to-let on revenue alone. The modelled regional average occupancy of 77% is healthy by London standards, but spread across only 90 nights it generates about £30,000, less than half the buy-to-let figure. Pushing occupancy harder cannot close the gap; the cap is the cap.

Planning permission for genuine commercial short-let use is theoretically available from Westminster City Council but is rarely granted in residential buildings, and applications are scrutinised closely. Platforms enforce the cap automatically: Airbnb blocks bookings beyond 90 nights for London addresses unless the host uploads evidence of permission.

Buy-to-Let Income Is Steady, but the Yield Is Thin at 1.9%

Westminster's gross buy-to-let yield of 1.9% sits 2.7pp below the London average of 4.6% and 3.8pp below the UK average of 5.7%. That is not a bug in the data; it is the central London tax for owning a prime postcode. Sale prices here run more than four times the London average and roughly twelve times the UK average, while rents climb only modestly faster than London-wide rents.

The investor case for a Westminster buy-to-let leans on capital growth rather than rental income. A property in Mayfair, Belgravia, or St John's Wood is bought for what the postcode is expected to be worth in ten or twenty years, with rent treated as a partial offset against holding costs rather than the primary return. Buyers accept the thin yield because Zone 1 land values have historically compounded faster than central London rents.

Westminster Yields Vary More Than the Headline Suggests

Within Westminster, gross yields stretch from the low 2% range in Belgravia and the SW1A core to over 3% in less prime postcodes. Pimlico/Victoria leads the area on yield: Pimlico/Victoria (SW1V) delivers 3.3% on a sale price of about £1.69m, the highest in the area despite still sitting more than five times the UK median price. Bayswater/Paddington and the SW1P fringe of Pimlico run between 2.8% and 2.5%, while Belgravia/Knightsbridge and the Whitehall/Buckingham Palace cluster compress to 2.5% and 2.3% respectively.

Bedroom count drives further variation. A 2-bed apartment at about £863,000 renting for about £3,400 produces a different yield profile from the 3-bed house figures driving these tables, and within a single postcode mansion blocks, mews houses, and stucco terraces price very differently. The headline 1.9% is the area median; what your specific property does depends on the building, the floor, and the lease structure.

Operating Costs Are High, but Buy-to-Let's Edge Holds

Buy-to-let operating costs in Westminster run to roughly £20,000 per year, covering letting agent fees at around 10%, landlord insurance of about £3,300, and maintenance of about £10,000. Council tax is typically the tenant's responsibility on a buy-to-let, so it does not enter the investor's running costs, although the landlord becomes liable during void periods. After costs, net operating income lands near £42,000, equivalent to a net yield of 1.3%.

Holiday let costs are higher in absolute terms and proportionally far higher relative to revenue. Self-managed annual costs reach about £26,000, leaving net operating income of just about £3,700 and a net yield of 0.1%. The line items: Airbnb host fees of around 15.5% of gross revenue (roughly £4,600 per year), holiday let insurance of about £7,400, utilities of about £2,100, and short-term rental-grade maintenance of about £12,000 including furnishing wear from guest turnover. A holiday let in Westminster may also be assessed for business rates rather than council tax, and many qualify for Small Business Rate Relief, reducing this cost to £0; the dashboard models council tax at about £16,000 as a conservative default.

Furnishing the property to a holiday let standard adds an upfront about £14,000 that does not appear in the running cost line but should be added to the cost base when assessing year-one returns. If you choose to hire a professional manager rather than self-managing, add roughly £5,400 per year, which would push holiday let net income negative on this market's economics.

Tax Implications for Westminster Investors

The Furnished Holiday Lettings (FHL) tax regime was abolished from April 2025, removing the historical tax advantage that had made holiday lets the more tax-efficient option. Holiday lets and buy-to-let in Westminster are now taxed equivalently as property income, which makes the financial comparison between holiday letting and buy-to-let more important than ever, since there is no longer a tax wedge favouring holiday let income.

Mortgage interest relief is restricted to a 20% basic rate tax credit rather than a full deduction, which hits Westminster investors particularly hard. The rate of tax on your next dollar of income, your marginal tax rate, is likely to be 40% or 45% for buyers at this price point, but interest is only credited back at 20%, so a highly leveraged purchase can leave a 40% taxpayer with a tax bill on income they did not actually keep. Many Westminster investors hold property through limited companies to preserve full interest deduction, though this comes with its own corporation tax and dividend tax considerations.

Stamp duty on a £3.28m purchase is substantial and is amplified by the 5% additional-property surcharge for second homes and buy-to-let purchases. Specific liability depends on whether the purchaser is a UK resident, a non-UK resident (which adds a further 2% surcharge), and whether the property is classified as residential. Verify current rates with your solicitor before committing. Capital gains tax on residential disposals runs at 18% basic rate or 24% higher rate from October 2024.

Westminster Sits Far Above Both London and UK Benchmarks

Comparison of key investment metrics.

Westminster's sale price sits more than four times the London average and roughly twelve times the UK average, while rents are only just over twice the London average. Yields are mathematically lower because rent climbs slowly relative to capital values in prime markets. This is the appreciation-yield trade-off that defines premium central London: you accept thin running income in exchange for the scarcity premium attached to a Zone 1 address. The After All Costs, Bromley's Holiday Let Loses to Buy-to-Let story is broadly similar across other prime central London boroughs.

Investment Bottom Line

Buy-to-let is the only viable income strategy in Westminster under the 90-night cap, and even then the 1.9% gross yield only makes sense for investors whose return thesis rests on capital appreciation rather than running cash flow. Holiday let economics are constrained at the revenue ceiling, with about £39,000 representing the absolute maximum gross at full occupancy across every permitted night, less than buy-to-let's about £62,000 before costs are even subtracted.

Westminster suits buyers who can put a large equity slice into the purchase rather than relying on high leverage. At these prices the 20% mortgage interest cap leaves a heavy tax footprint for higher-rate buyers, and the thin gross yield offers little buffer against rate rises. Cash and lightly leveraged investors fare better here.
