If you are only conducting lifetime mortgage business then you do not require any further permissions if you already have the permissions to give advice on mortgages (‘advising on regulated mortgage contracts’). This is because lifetime mortgages are considered by the FCA as a regulated mortgage and therefore falls under the normal mortgage permissions.
If however, you wish to advise on both lifetime mortgages and home reversion plans then you will need additional permissions covering home reversions (‘advising on a home reversion plan’) as well as permission to advise on or arrange regulated mortgage contracts.
