Here I will be providing some links to places you can put your savings in order to earn higher rates than are normally available at the high street banks.
Carefully check that you are happy with the conditions and seek professional financial advice if you are unsure about anything being offered to you.
However, money is often best invested in property; high-interest savings accounts are preferable if you are intending not using your money for property investment for some time. In recent times such places have ceased to exist but investment remains a possible higher return option (as long as you accept the associated risks of course).
There are also other property investment options where you can put your investment into a passive property investment such as a provider of crowd funding to those needing the money.
Check that you can access your money as you need to (depending on how you expect you will need access to your money in future).
