Free regular investing

Invest monthly with no trading fees. A simple way to invest. 

Make the most of your spare cash

What is regular investing?

Regular investing means topping up monthly - rather than investing a lump sum all at once. It is the 'little and often' approach to investing, which can be less risky and more profitable.

By regularly drip-feeding your money into the stock market, you will end up buying shares at different prices. When prices go up, your money will buy fewer shares. When prices drop, it will buy you more.

Snapping up shares in this way, rather than with a hefty lump sum, is known as pound-cost averaging.

If the market goes through a rough patch, regular investing helps cushion the impact. It does not guarantee better returns than investing a lump sum but, over a fixed period, you will have paid the average price of the share. This reduces your risk and gives you a smoother return.

How does regular investing work?

Say you buy £100 of shares a month. In the first month the share price is £5, so you can buy 20 shares. In the second month, the price falls to £4. But you can now buy 25 shares for £100.

Holding 45 shares in total, you are now better placed to profit when the price picks up.

By spreading the investment – £200 over two months – those 45 shares were bought at an average price of £4.44 each. Investing £200 in one go would have bought only 40 shares, at a cost of £5 each.

    Due to the popularity of our regular investing service, investments are now spread over two dates each month. Customers who saved instructions before Wednesday 5th May 2021 will retain the trading day of the 3rd Wednesday of each month. Customers who save instructions for the first time after this date will have a trading date of the 1st Wednesday of each month. Your next investment date is shown in the regular investing page of your account.

Between these dates your cash balance will show a higher figure, before the regular investments have taken place.
