How is my rent calculated? | 2026 Shared Ownership Rent and Service Charges FAQs

Every year, we review rents in line with the terms of your shared ownership lease. While each lease differs, and the terms are specific to you, these are often based on Retail Prices Index (RPI) in September 2025 plus 0.5%, or by 0.5%, whichever is higher. The calculation for your rent will be included with the FAQs mailed to you. 

This year, RPI for September 2025 was 4.5%. RPI is a government published measure of inflation.
