Property Price & Volume Trends
The average property price in SL1 is £416,000, placing it among the more expensive districts nationally. Over the past decade, prices have grown at 4.3% annually—a pace faster than the national average. However, transaction activity has weakened noticeably: last year saw 489 sales compared to a 10-year average of 722 per year, suggesting a marked slowdown in market momentum.
Rent & Yield Trends
Average monthly rent in the broader SL area stands at £1,633, well above the national norm. Rental growth over the past decade has been steady at 4.0% per year, tracking close to the national median pace. The flat yield has improved to 4.5% in the latest year from a 10-year average of 3.7%, indicating a modest but welcome uplift for investors.
Income & Affordability Trends
Average household income in SL1 is £43,933, placing the area above the national median. Purchase affordability has deteriorated: the price-to-income ratio now stands at 8.8x, up from 7.6x in 2016, reflecting faster price growth than income gains. Rental affordability has also tightened slightly, with rent now consuming 32.4% of household income compared to 31.4% a decade ago.
Resident Demographic Profile
The area skews noticeably younger and family-oriented: 23.9% are under 15—well above the national average of 17.5%—while those aged 35–49 represent 25.1%, considerably higher than the 18.7% national figure. The housing tenure profile is distinctive, with private rental accounting for 35.2% of households—far above the 21.7% national average—and outright ownership much lower at 20.3% versus 33.7% nationally. Employment is weighted heavily towards elementary roles (13.6% versus 10.2% nationally) and plant/machine operatives (9.1% versus 6.6%), reflecting Slough's industrial and logistics heritage.
