Strawberry Invest managing director James Priday said: “With the right information, accessible online technology, and a more interactive form of saving, i.e. investing, people will put more money away for their future. The key is to make saving both simple and interesting.

“We are certainly not advocating dispensing with the services of a financial adviser, especially those with fairly complex financial affairs, but believe that people with simpler affairs should have the tools and information to manage their own savings and investments.”

Investments can be held within a general investment account (GIA), Stocks & Shares ISA (ISA) and a self-invested personal pension (SIPP).

An account can be opened with a lump sum of £1,000 or regular contributions of £100 monthly for the first year. Subsequent contributions must be a minimum of £100.
