A Stocks and Shares ISA allows you to invest up to £20,000 a year without paying tax on your gains. You can access your money at any time. Many people start with an ISA for the tax benefits, and then move on to a Trading Account for the rest of their investing.

General investment (trading account)

These accounts (Trading Account, Joint Trading Account and Company Account) give you the flexibility to invest on your terms. There is no upper limit on how much you can invest, and you can withdraw your funds at any time. However, they do not have the tax advantages of an ISA.


SIPP (Self Invested Personal Pension) is a long-term investment with important tax benefits. Every contribution you make to your SIPP will receive a boost in the form of tax relief. You can invest up to 100% of your annual earnings (capped at £40,000). Once you reach 55 you can access our full range of flexible retirement options.
