About UB4

UB4 is a quietly residential corner of Hillingdon that appeals primarily to families and those prioritising good schools over urban buzz. The area has a suburban character with decent green space and a solid community feel, though it's not particularly lively or cosmopolitan—with a liveability score of 51/100, it trades some vibrancy for stability and affordability. Properties cluster around £485k, making it accessible for first-time buyers and growing families compared to many London postcodes. It's best suited to people who value a peaceful neighbourhood and are willing to sacrifice some of the convenience and energy you'd find closer to central London.

Safety is a genuine strength here, with a crime rate of just 15.4 per 1,000 residents and an excellent safety score of 90/100, well below London's average. Schools are uniformly strong across the district with a perfect 100/100 score—every school is rated Good or Outstanding—which is a major draw for families. Transport is the trade-off: with an average PTAL of 2.0 and a transport score of 53/100, you'll need a car for most errands or accept longer journey times to central London. This makes UB4 ideal for car-owning families and remote workers, but less suitable for those relying on public transport or commuting frequently into town.
