Westminster Buy-to-Let Earns Nearly Double the Holiday Let

Buy-to-Let Grosses Nearly Twice What Holiday Lets Can Earn in Westminster

Estimates for a typical 3-bedroom house. Figures are modelled from market data; not guaranteed outcomes.

⚠ Holiday let figures reflect the 90-night annual cap that applies across all London boroughs under the Deregulation Act 2015. Exceeding 90 nights requires planning permission from Westminster City Council.

Buy-to-let grosses roughly £66,858 per year, nearly double the holiday let's estimated £35,276. The 90-night cap is the primary constraint: even at 100% occupancy during those 90 nights, a holiday let would gross only around £45,450, still well below buy-to-let income. Holiday let operating costs (furnishing, cleaning, insurance, platform fees) widen the gap further.

Holiday let only outperforms buy-to-let if occupancy exceeds 100% of available nights, which is physically impossible. The maths is straightforward: annual rent of £66,858 divided by the nightly rate of £505 across 90 available nights gives a break-even occupancy of roughly 147%. Buy-to-let wins in Westminster at any realistic occupancy level.

Occupancy Sensitivity

Even though buy-to-let wins at every occupancy level, the gap widens dramatically as bookings soften. At 63% occupancy (a realistic scenario during quieter months), gross holiday let revenue drops to around £28,461. At the borough average of 78%, it reaches approximately £35,276. Even at an optimistic 88%, gross revenue only climbs to around £39,819. In every scenario, buy-to-let's £66,858 annual rent is comfortably ahead, before accounting for the higher operating costs that holiday lets incur.

Yields Vary Across Westminster's Postcode Areas

Westminster is not one market. Gross buy-to-let yields vary significantly across the borough's postcode areas, and the right postcode can mean the difference between a viable investment and dead money.

The spread is striking. Mayfair/Savile Row (W1S) delivers an estimated 6.8% gross yield on a lower entry price of £936,236, while Strand/Covent Garden (WC2R) yields approximately 4.0% on a price tag of £1,613,029. Whitehall/Buckingham Palace (SW1A) commands the highest rents at roughly £9,921 per month, but its £2,000,000 price point brings the yield back to 6.0%. The pattern is consistent across prime London: higher absolute rents do not necessarily mean higher yields.

These are borough-level averages per postcode area. The dashboard breaks it down further, by bedroom count and property type, so you can model your specific property.

The 90-Night Cap Makes Holiday Letting a Side Income, Not a Strategy

Westminster falls under the London-wide 90-day rule established by the Deregulation Act 2015. Any property let for more than 90 nights per calendar year without planning permission is in breach, and platforms like Airbnb automatically block bookings once the threshold is reached. Obtaining planning permission for a change of use to holiday let accommodation is possible in principle, but Westminster City Council is among the most restrictive boroughs in London. Approval is far from guaranteed, particularly for residential properties.

For investors, this cap transforms the holiday let question entirely. With only 90 nights available, even a strong nightly rate of £505 cannot generate enough revenue to match a tenanted buy-to-let. The maximum possible gross (at an impossible 100% occupancy over 90 nights) would be approximately £45,450, roughly two thirds of the buy-to-let's £66,858. Add the 15.5% Airbnb platform fee, higher insurance costs, cleaning between guests, and furnishing requirements, and the net position deteriorates further.

Some investors run a hybrid approach: letting on a long-term assured shorthold tenancy for most of the year and switching to holiday let during peak tourist periods. This requires careful contract structuring and is not straightforward in Westminster, where the council actively monitors short-term letting activity. For most investors, a straightforward buy-to-let is the cleaner, more profitable path.

Westminster's Operating Costs Take a Large Bite From 3.0% Gross Yield

A 3.0% gross yield sounds thin. After costs, it thins further. Understanding the full cost stack is critical before committing to a market where entry prices start at nearly £936,236 for a 3-bedroom house.

For a buy-to-let property at the median price of £2,194,108:

• Council tax: estimated at 0.5% of the property value, roughly £10,971 per year (typically paid by the tenant during a tenancy, but the landlord bears it during void periods)
• Letting agent fees: around 10% of monthly rent for a managed service
• Landlord insurance: estimated at £2,482 per year
• Maintenance and repairs: approximately £10,163 per year for a property at this price point

For a holiday let, the cost base is significantly higher:

• Airbnb host fee: 15.5% of each booking (deducted before payout)
• Holiday let insurance: around £6,175 per year
• Cleaning per turnover: approximately £65 per guest changeover
• Furnishing: roughly £13,500 upfront for a 3-bedroom house
• Utilities: around £2,088 per year (borne by the host, not the guest)
• Letting agent or co-host fees: typically 18% of revenue for a fully managed service

The cost differential reinforces the buy-to-let case. Holiday let operating costs consume a far larger share of an already smaller revenue figure. After platform fees and management costs alone, the holiday let's £35,276 gross could shrink by a third or more.

After Tax, Buy-to-Let Remains the Clear Winner in Westminster

The Furnished Holiday Lettings (FHL) tax advantage has been removed. Since April 2025, holiday lets and buy-to-let properties are taxed equivalently, making the financial comparison between holiday letting and buy-to-let more important than ever. Previously, holiday let operators could deduct mortgage interest in full; now, all residential landlords are restricted to a 20% basic rate tax credit on mortgage interest payments.

For a Westminster investor with a mortgage, this restriction is material. On a property worth £2,194,108 with a 75% LTV mortgage at current rates, the annual interest alone would be substantial. The basic rate credit means higher-rate taxpayers (40% or 45%) face an effective tax increase compared to full deduction, and this applies equally whether you let on a buy-to-let or holiday let basis.

Stamp duty adds to the upfront burden. The 5% surcharge on additional residential properties (from October 2024) applies on top of the standard bands. On a Westminster purchase, this is a significant five-figure sum. Transaction costs are complex and banded; check current rates with your solicitor before committing.

Capital gains tax on residential property disposal stands at 18% for basic rate taxpayers and 24% for higher rate taxpayers (from October 2024). In a market where appreciation is a core part of the investment thesis, understanding your CGT position matters. Allowable deductions include stamp duty paid, improvement works, and professional fees.

Allowable revenue expenses for both strategies include repairs, insurance, letting agent fees, and ground rent (for leasehold properties, which are common in Westminster). The key difference is that buy-to-let's higher gross revenue provides more headroom to absorb these costs and still deliver a positive net return.

Westminster Yields Trail the London and UK Averages by a Wide Margin

Comparison of key investment metrics.

Westminster's 3.0% gross yield sits well below both the London average of 4.6% and the UK average of 5.6%. The reason is simple: prices are extreme. At £2,194,108 for a typical 3-bedroom house, Westminster costs roughly 3.5 times the London average of £631,954 and over eight times the UK average of £256,225. Rents are high in absolute terms (£5,571 vs £2,448 for London and £1,197 nationally), but not high enough relative to prices to deliver a competitive yield.

This is the defining characteristic of a premium market. Investors who buy in Westminster are not primarily buying cash flow. They are buying into one of the world's most resilient property markets, where values are underpinned by global demand, limited housing stock, and a borough that includes Mayfair, St James's, and Belgravia. Our data sources confirm that prime central London has historically delivered capital appreciation well above the national average, even through downturns.

For investors focused purely on yield, markets outside London offer substantially better returns. Several boroughs beyond Zone 1 deliver higher gross yields with lower entry prices. The trade-off is lower appreciation potential and, in some cases, higher void risk. Westminster's tenant demand is among the strongest in the country, which reduces the risk of extended void periods that can erode yields elsewhere.

Westminster Is an Appreciation Play, Not a Cash Flow Market

The numbers tell a consistent story. Buy-to-let dominates holiday letting in Westminster by a wide margin, primarily because the 90-night cap limits holiday let revenue to roughly half of what a tenanted buy-to-let produces. Even without the cap, Westminster's high operating costs and the abolition of FHL tax relief would make holiday letting a marginal proposition at best.

But the more important question for Westminster is whether buy-to-let itself makes sense at a 3.0% gross yield. The answer depends entirely on your investment thesis. If you need cash flow to service debt and cover costs, Westminster is a difficult market. A highly leveraged purchase at these prices will likely produce negative cash flow after mortgage payments, even with rents of £5,571 per month.

If your thesis is capital preservation and long-term appreciation in a globally recognised market, Westminster remains compelling. The borough's property values are supported by structural scarcity (Grade I and II listed buildings, conservation areas, limited new supply), international demand, and proximity to the UK's centres of government, commerce, and culture. These fundamentals do not change with interest rate cycles.

Westminster rewards patient capital. Investors who can absorb low yields in exchange for long-term value growth will find a robust market with deep tenant demand. Those seeking immediate returns should look to higher-yielding boroughs or regional markets, where entry prices are lower and gross yields can exceed 5% or 6%. Higher-yielding boroughs within commuting distance offer examples of what stronger yield profiles look like.

Whichever strategy you pursue, the borough-wide averages above mask significant variation.
