Right now, 5.6 tenants are chasing every available rental home in London, and there are roughly a quarter fewer properties to rent than before the pandemic. For anyone looking at the London rental market, that imbalance is the single biggest force shaping what a property can earn. Average new-let rents across the UK hit £1,321 in June 2026, and London sits well above that — inner-London one-bedrooms commonly run £2,000 to £2,500 a month. The catch is that yields vary wildly depending on which borough you buy into, and recent tax changes have shifted the maths for landlords.

London is not one market. It is 32 distinct boroughs, and conditions vary more than most people expect. A flat in Kensington and Chelsea will set you back over £1 million, while in Barking and Dagenham the average is around £355,000. Yet the rent gap is narrower — about £1,411 a month in Bexley versus £3,615 in Kensington and Chelsea. That difference matters because it tells you where the income-to-price ratio works harder. Add in a population that is forecast to reach 9.97 million by 2043, and the long-term demand picture starts to look fairly solid. The question is how to pick a strategy that actually lines up with the numbers. Here’s what you actually need to know.
One term you will hear constantly in this market is rental yield. It is simply the annual rent a property generates divided by its purchase price, shown as a percentage. A 5% yield on a £500,000 flat means £25,000 in rent before costs. But the number you see quoted is usually gross — it does not account for mortgage payments, letting agent fees, repairs, or tax. What I tend to notice is that people fixate on the gross figure and forget that the net number is what actually pays the bills. A good gross yield in London right now sits around 5% to 6%, though prime central areas can drop as low as 2% to 3% because buyers there are chasing capital growth rather than income.

Where the numbers land — yields, rents, and the 90-day limit
Yields shift noticeably as you move across London. The best returns are in east and south-east postcodes where property prices are lower but rents hold up reasonably well. The table below shows gross yields for some of the strongest areas, based on recent data from Track Capital. These are snapshot figures — yields move as prices and rents change.

| Postcode area | Gross yield | What it means per £500k property |
|---|---|---|
| East Ham (E6) | ~6% | ~£30,000 annual rent before costs |
| Thamesmead (SE28) | ~5.9% | ~£29,500 annual rent |
| Stratford, West Ham (E15) | ~5.8% | ~£29,000 annual rent |
| Abbey Wood (SE2) | ~5.8% | ~£29,000 annual rent |
| Tottenham (N17) | ~5.8% | ~£29,000 annual rent |
| Plaistow, Upton Park (E13) | ~5.7% | ~£28,500 annual rent |
| Hackney, Homerton (E9) | ~5.5% | ~£27,500 annual rent |
| Bethnal Green, Shoreditch (E2) | ~5.4% | ~£27,000 annual rent |
| Dulwich (SE21) | ~5.2% | ~£26,000 annual rent |
| Upper Holloway, Archway (N19) | ~5% | ~£25,000 annual rent |
Those numbers are gross, so mortgage interest, service charges, and tax all come off the top. A property in East Ham grossing £30,000 might net £18,000 to £20,000 after a typical mortgage at current rates, depending on your tax band. The key point is that an extra percentage point of yield makes a real difference once costs are stripped out.
Tax treatment also matters more than it used to. The Furnished Holiday Lettings regime was abolished in April 2025, removing the old tax perks for short-let landlords. Mortgage interest relief is now restricted to a 20% basic-rate credit for all residential landlords, no matter your tax band. And local councils can charge up to a 100% premium on council tax for second homes. If you are weighing up a buy-to-let, it is worth running the net figures with these costs included.

Where investors most often misread the market
Most of the costly mistakes in London rental investing come from assuming the city works like a single market. The research shows three or four errors that crop up again and again. Each one has a straightforward fix, but only if you know it exists.
Treating London as one market
A property in Kensington and Chelsea and one in Barking and Dagenham are both in London, but they behave nothing alike. The first might cost over £1 million and yield 2% to 3%; the second costs around £355,000 and can yield closer to 5% or 6%. The mistake is looking at a London average — around £542,000 — and assuming that represents your likely purchase. It does not. You need to pick a specific borough or even a postcode and run the numbers for that area. The rental disparity is smaller than the price disparity, which is why lower-priced boroughs often deliver better income returns.
Ignoring the 90-day cap on short lets
Plenty of people assume they can list a London property on Airbnb or Booking.com and fill it year-round. The 90-night cap means that is not possible without planning permission. A property that could earn £42,000 to £50,000 annually as an unconstrained short-let is limited to roughly one-quarter of that if you stay within the 90-day rule. The common workaround is a hybrid model — short-let during the 90 most profitable nights and mid-term let the rest. That spreads the income across the year without running into the planning restriction.
Overlooking the recent tax changes
The abolition of the Furnished Holiday Lettings regime in April 2025 removed the ability to claim full mortgage interest relief and other tax advantages on short-let properties. For higher-rate taxpayers, that shift alone can add thousands to the annual tax bill. Combined with the restriction on mortgage interest relief to a 20% credit for all landlords, the net return on a rental property can look very different from what it was a few years ago. If you are buying now, the post-tax calculation matters more than the gross yield.
Underestimating how tight supply keeps rents supported
New build starts fell to 11,700 in Q3 2024, a 13% drop year-on-year and 65% below the 2014 peak. Planning applications rose 78% in the same period but remain 46% below their peak. That means fewer homes are coming to market, and the pipeline is not catching up anytime soon. The practical effect is that rents are unlikely to fall sharply even if demand softens. For a landlord, that is a structural support, not a short-term trend.

How to build a strategy that fits the current market
The research points to a few clear paths depending on what you want from a London rental property. The main choice is between long-let, short-let, and a hybrid approach. Each has a different set of rules, tax treatments, and income profiles.
Long-let: steady income with fewer moving parts
A standard assured shorthold tenancy gives you a tenant for 6 to 12 months, predictable monthly rent, and no 90-day cap. The trade-off is lower gross yields — typically 4% to 5% in the better outer areas — and less flexibility to use the property yourself. The main advantage is that you are not constantly managing turnover, cleaning, and guest communication. For a landlord who wants a passive-ish income stream, this is the lower-effort option. Mortgage interest relief is restricted to a 20% credit, so factor that into your net return calculation.
Short-let: higher income, tighter rules
A short-let property can generate £150 to £260 per night in London, with median annual revenue of roughly £42,000 to £50,000 for an unconstrained listing. But the 90-day rule caps whole-property bookings at 90 nights per year without planning permission. That means you cannot run a full-time short-let in London without either exceeding the limit or applying for change-of-use planning permission. The abolition of the Furnished Holiday Lettings regime also removed the tax advantages that used to make short-lets more attractive. This option works best for landlords who are willing to manage active turnover and can optimise pricing around peak demand periods.
The hybrid model — what most experienced landlords are moving toward
A hybrid approach uses the 90 short-let nights during the highest-demand periods — summer, major events, Christmas — and then switches to mid-term lets (one to three months) for the rest of the year. A single booking of 90 or more consecutive nights counts as a tenancy, not a short let, so it resets the 90-day count. This model spreads income across the year while staying within the rules. The steps to set it up are straightforward but require planning.
-
1Check the 90-day cap against your calendarMap out peak demand periods (summer, holidays, major events) and allocate your 90 nights to those windows. The cap resets 1 January each year.
-
2Set up a mid-term let structure for the rest of the yearA single booking of 90 or more consecutive nights is treated as a tenancy, not a short let, and does not count toward the 90-day cap. Target professionals, contractors, or students for these stays.
-
3Use a property management platform that handles bothSome services specialise in hybrid management — 24/7 guest communication, pricing optimisation, cleaning, and maintenance across both short and mid-term bookings. Compare fees before signing.
-
4Review your tax position each yearWith the FHL regime gone, all rental income is now taxed the same way. Keep clear records of income, expenses, and the number of short-let nights used.
What is changing next — the emerging regulatory picture
London’s rental market is not static. The 90-day rule could be tightened, and some boroughs have already discussed introducing local registration schemes for short-lets. The government has also signalled further consultation on the short-let sector, including potential safety and licensing requirements. On the tax side, the abolition of the FHL regime is already in effect, but the full impact is still working through because many landlords had existing properties structured under the old rules. If you are buying now, you are starting from the new baseline, which makes the maths simpler.

Supply constraints and demand pressure still favour the long-term owner
The combination of 5.6 tenants per home, 25% fewer rental properties than before the pandemic, and construction starts at a 10-year low paints a clear picture: London’s rental market is structurally undersupplied. That does not guarantee rising rents every year, but it does suggest that income is unlikely to collapse. The main risk for investors is not demand — it is buying the wrong property in the wrong borough at the wrong price, and then getting caught by tax rules that have shifted against landlords. The investors who do well in this market tend to focus on one or two postcodes, run the net numbers honestly, and choose a letting strategy that fits the 90-day rule rather than fighting it.
