You probably have the Right to Buy if you’re a secure council tenant and have spent at least 3* years as a public-sector tenant. The 3 years doesn’t have to be continuous, and you can add together any time you have spent as a public-sector tenant. A public-sector tenant is someone whose landlord is a public body such as a council, housing association or government department. Eligibility criteria also include having no legal issues with debt or any outstanding possession orders. You should be aware that some properties are exempt from the Right to Buy.
* In May 2015, the eligibility criteria for Right to Buy was reduced from 5 years public sector tenancy to 3 years.
