Key Points
- London’s most desirable neighbourhoods are unaffordable for all but the wealthiest tenants, with rental pressures now impacting mid-tier areas.
- Rents in mid-priced areas (£876 to £966 per month) are rising fastest, outpacing even top-tier postcodes, as people get pushed outwards to places like Brockley and Bethnal Green.
- According to Matt Hutchinson, director at Spareroom, rents fall fastest in the priciest areas but rise quickest in cheaper areas as tenants move further from prime locations, eroding affordability.
- Average monthly rents for rooms in London hover around £1,000, making it very challenging to save for home deposits or live affordably.
- South London’s Clapham, once affordable for young renters, now has average rents over £1,000 per month, causing tenants to move to more affordable neighbourhoods like East Dulwich.
- Prices in areas such as Blackheath and Brockley are soaring, with year-on-year increases of around 8-9%.
- Prime London private rental tenants spend an average of 42% of their income on rent, exceeding the UK average, with some boroughs like Kensington and Chelsea spending nearly 75% of income on rent.
- Landlords express concern that costly government regulations and impending national insurance taxes on rental income could worsen the supply shortage as many landlords exit the market.
- Commercial office rents in Central London continue to rise modestly, driven by a shortage of grade A office space, with some Mayfair rents exceeding £215 per sq ft annually.
- The squeeze on residential rentals is pushing many tenants to commuter towns, while office rental markets remain tight in prime districts like Mayfair, Marylebone, and Fitzrovia.
What is causing the spillover effect of rents from central to outer London?
As reported by Matt Hutchinson, director at Spareroom in a Bloomberg analysis published by The Business Times, “London’s most desirable neighbourhoods are out of reach for all but the most affluent tenants, and the effects are rippling out.” The core issue is that tenants priced out of extremely expensive central areas are moving into mid-tier neighbourhoods, causing those to become less affordable in turn. Hutchinson explained, “Usually what happens when people are squeezed is that rents fall fastest in the most expensive areas and rise quickest in the cheapest, but also renters get pushed further out into slightly more affordable neighbourhoods.” This dynamic is causing rapid rent increases in mid-priced areas ranging from £876 to £966 monthly, escalating by 1.3% in the year up to the third quarter of 2025. The ripple effect is steadily eroding the remaining pockets of affordability within London, forcing many to look further afield for housing options.
Which neighbourhoods are experiencing the highest rental increases?
The rise in rents is particularly marked in south-east and east London neighbourhoods. Blackheath’s rents surged 9 percent year on year to £959 monthly, an annual increase of approximately £950. Nearby Brockley witnessed an almost 8 percent rise to £911 per month. Similarly, Clapham in South London, a historically sought-after area for young renters, now sees average room rents above £1,000 a month, pushing tenants to more affordable areas like East Dulwich, which offers savings of about £183 per month (roughly £2,200 annually). By contrast, super-prime areas such as Camden, popular with students and professionals, have experienced slight declines but remain costly, with rents averaging over £1,200 per month.
How much of their income are London tenants spending on rent?
Official private rental data cited by Spareroom shows that typical tenant households in London are spending nearly 42 percent of their income on rent, significantly above the English average of roughly 36 percent. This ratio is even more severe in certain boroughs: Westminster, Wandsworth, Camden, and Hammersmith & Fulham top 50 percent, while Kensington and Chelsea approaches an extraordinary 75 percent. These figures highlight the untenable burden on London renters as housing affordability deteriorates, compounding the challenge of saving for home ownership.
What are landlords’ views on the rental market challenges?
Landlords attribute part of the squeeze to government policy, claiming that expensive regulations have contributed to reducing rental supply. There is also apprehension about Chancellor Rachel Reeves’s planned national insurance tax on rental incomes set for the November 26th Budget, which many fear will drive landlords out of the market. As landlord numbers decline, the chronic undersupply worsens, perpetuating high rents. Hutchinson emphasised, “Because of chronic undersupply in the London rental market, rents are stubbornly high and meeting affordability criteria – not spending more than 30 percent of your salary on rent – is rarely possible. Hardworking people the capital relies on to function have little choice but to leave”.
How are commercial office rents in Central London performing amid the residential rental crisis?
Meanwhile, commercial rents in Central London continue their upward trajectory due to a tight supply of premium Grade A office space. According to the Central London Net Effective Rents Monitor Q2 2025 by Carter Jonas, headline rents increased by 1.3% in the second quarter of 2025, with a 5.6% rise year-on-year driven by fierce competition for prime locations. The West End’s Mayfair district saw record rents, exceeding £215 per square foot per annum for “super-prime” office space on upper floors of 77 Grosvenor Street. Other West End areas such as Marylebone, Fitzrovia, and Victoria have also shown strong rental growth. The West End submarket outperformed others with a quarterly rent increase of 3.8%, followed by more moderate gains in Midtown and the City of London. Docklands, by contrast, remained flat.
Which locations are tenants turning to as rents soar in London?
With rents in London’s core becoming unattainable for many, demand is rising in commuter towns and suburbs, including St Albans and Brentwood. This trend reflects the growing need for affordable accommodation within reachable distance of Central London. The expansion of the spillover rental effect underlines the increasing geographic dispersion of housing pressure as affordability evaporates.
These developments showcase the complex housing issues in London where residential renters face untenable price increases, landlords are disincentivized by tax and regulation changes, and commercial property remains a highly competitive, high-value space. Navigating these challenges requires expertise in property, finance, and legal compliance.
