The fact that it's still available means that those who are eligible to buy them (self-employed or in employement and not a member of an pension scheme) can still buy Pension Term Assurance products. Those who have PRSAs cannot, after the changes to that product on 01/01/2023 and no news on whether thats' going to be fixed.
The life cover doesn't suit everyone as it's non-assignable but the tax relief on premiums (up to age related limits and combined with pension contribution) is attractive.
