Santander Digital Adviser is the bank's new service and is regulated financial advice delivered online for a £20 advice fee. 

Lots of questions test how you feel about risk and how you want your investments to behave. There's a strong behavioural finance slant. 

At the end of the questionnaire you can buy a suitability report for £20 which will tell you how to invest and start.

This option will lead to a range of Santander 'multi-asset funds' and will not suit those looking for broader fund choice or the ability to trade shares. The older Investment Hub offers access to third-party funds although it's not the best option on the market if you're after full choice.

Costs are £20 for the advice, the platform or administration fee costs 0.35% a year and then the underlying funds cost from 0.34% a year to 0.49% a year, depending on the mix of assets contained. Expect to pay about 0.8% a year all-in plus the initial outlay of £20 for the suitability report.
