The British Property Federation (BPF) and Savills have published research indicating that planning consent times for build-to-rent homes in London have doubled over the past six years, rising from an average of 8 to 15 months. This is 150% longer than the statutory time limit for major applications. The research also shows that the number of build-to-rent homes under construction fell by 17% nationally, from 59,874 to 49,984, and by 29% in London, from 17,138 to 12,134, representing the ninth consecutive quarterly decline. The number of build-to-rent homes in the planning pipeline increased by 2% across the UK and by 6% in London, rising from 36,559 in Q1 2025 to 41,968 in Q1 2026, although schemes at the application stage fell by 17% over the same period. The BPF attributes delays to the impact of the Building Safety Regulator and cites wider regulatory pressures, including the incoming Renters' Rights Act. It also notes that 80% of the build-to-rent pipeline now consists of schemes with more than 100 homes, reflecting viability challenges. The analysis further highlights that build-to-rent accounts for 8% of all new homes delivered in the UK.
