Shared ownership rent reviews (UK): what typically changes and when

Shared ownership rent reviews usually happen yearly and are set out in your lease. Here’s what can change, when, and a tiny example.

The short answer

In shared ownership, you pay rent on the share you don’t own. A rent review is when your housing provider updates that rent — usually once a year — using the formula written in your lease (often linked to an inflation index).

Two important things to remember:

  • Rent reviews are separate from service charges (which can also change).
  • The exact rules depend on your lease and when it was granted.

A tiny example

Assume your current rent on the unsold share is £450/month and your lease allows an annual increase based on an inflation measure.

If the rent increased by (say) 5% at review:

  • New rent: (£450 × 1.05 = £472.50) per month

Your mortgage payment might stay the same, but your total monthly cost can still rise because rent and service charges can change on their own schedules.
