Holiday Let or Buy-to-Let in Westminster: What the Numbers Show
Verdict: Buy-to-let wins decisively. The 90-night London cap limits holiday let gross revenue to roughly £29,838 per year, while buy-to-let generates approximately £62,018, making holiday letting mathematically unable to compete.
Best For: Appreciation-focused investors comfortable with low yields on premium assets. Buy-to-let only; holiday let cannot break even under the 90-night rule.

Estimates for a typical 3-bedroom house. Figures are modelled from market data; not guaranteed outcomes.
Westminster's gross buy-to-let yield of 2.6% sits below both the London average of 4.6% and the national average of 5.7%. Property prices are several multiples higher than the London median, while rents, though high in absolute terms, do not scale proportionally. This is the classic premium market trade-off: lower yield, higher capital growth potential.
Investors in Westminster are typically not chasing cash flow. They are buying into one of the world's most resilient property markets, where scarcity of supply, international demand, and the prestige of a central London address underpin long-term appreciation. The rental income covers holding costs; the real return comes when selling. Our data sources track both yield and price trends across all UK markets.
For investors who prioritise yield over appreciation, other London boroughs offer meaningfully higher gross returns at lower entry prices. Markets like Edinburgh face similar regulatory dynamics but at different price points. The choice depends on whether your strategy is income-led or growth-led.
Investment Bottom Line: Westminster Is a Buy-to-Let Appreciation Play
Westminster is not a market for yield-chasing investors. With buy-to-let gross yields at 2.6% and holiday lets unable to break even under the 90-night cap, the investment thesis rests on long-term capital appreciation and the stability of prime central London property.
The numbers are clear: buy-to-let generates around £62,018 per year in gross rent, netting approximately £30,522 after costs (1.3% net yield). Holiday letting produces just £-7,156 net. There is no scenario within the current regulatory framework where holiday letting outperforms.
| Investor Type | Fit |
|---|---|
| Cash Flow Focused | Poor |
| Appreciation Focused | Excellent |
| Holiday Let Operator | Not Viable |
| High Leverage (80%+ LTV) | Poor |
High leverage is particularly risky at these price points. With gross yields at 2.6% and mortgage rates significantly above that, leveraged investors will be cash-flow negative from day one. Westminster works best for equity-rich buyers who can absorb negative cash flow in exchange for long-term capital growth.
