Your pension check will be free of charge. It gives you the opportunity to discuss general questions, and identify what steps, if any, you should take. It would ordinarily take around 30 minutes. To get the most possible from your pension check, have ready a summary of your financial situation (savings, debt, incomings, outgoings) and future plans.
If the financial adviser identifies any areas that require more detailed attention, they will be able to provide you with a clear price and proposal. There will be no obligation to continue with that proposal.
