How to invest with a business account

Here’s a simple, 4-step process for getting your company’s cash invested:

  1. Select a platform. Choose a regulated UK platform like the ones in this guide and complete a business account application. This is typically done online and involves providing company and director details.
  2. Get an LEI number. If you don’t have one, you must register for a Legal Entity Identifier (LEI). Some platforms can help you do this during the onboarding process.
  3. Fund the account. Once approved, you can transfer your surplus business cash from your company’s business bank account to the new investment account.
  4. Choose your investments. Select the funds, shares, or other investments that align with your company’s strategy, risk tolerance, and investment horizon.

What is a business investing account?

A business investing account, often called a Corporate Dealing Account or Company Investment Account, is basically a brokerage account held in the legal name of your limited company (or other legal entity).

It allows your business to invest its surplus cash into financial markets, separate from the owners’ personal finances. All capital gains, dividends, and interest are owned by the company and subject to Corporation Tax.

What can you invest in?

Most UK business investing accounts offer a diverse range of assets to help you diversify your company’s portfolio:

  • Shares. Individual shares in UK and international companies.
  • Funds and ETFs. Professionally managed passive or active baskets of investments that offer instant diversification.
  • Investment trusts. Publicly listed companies that invest in other assets.
  • Bonds and gilts. Debt securities issued by companies (bonds) or the UK Government (gilts), generally viewed as lower-risk investments.
  • Money Market Funds (MMFs). Highly liquid, low-risk funds that aim to provide returns slightly higher than a standard savings account.

Essential requirements for a business account

To open a company investment account in the UK, your business will typically need to meet the following criteria and provide documentation:

  • Legal structure. Must be a UK-registered Limited Company. Some providers may also accept Limited Liability Partnerships (LLPs). Sole traders must use a personal account (like a GIA).
  • Directors and owners. Details for all directors and beneficial owners.
  • Business details. Company registration number, registered address, and nature of business (SIC code).
  • Bank account. A UK business bank account, which is used to fund the investment account.
  • Legal Entity Identifier (LEI). This unique code is a mandatory requirement for any limited company that trades shares or other financial instruments on a regulated exchange.

Pros and cons

Pros

  • Potential to generate interest or profit on business cash
  • Tax-efficient way to invest while keeping money in the business
  • Maximise idle business cash and put it to work
  • Everything can be done digitally with some platforms

Cons

  • Investments can rise or fall in value
  • Tax advice from an accountant is usually best
  • You need to get an LEI
  • Accessing the funds outside of the business can be complex

Our expert says: What is a LEI Number?

"A Legal Entity Identifier (LEI) is a unique, 20-character alphanumeric code required by regulatory bodies for any legal entity (like a UK limited company) that wants to trade financial instruments on a regulated exchange.

It was introduced following the 2008 financial crisis to create a global, transparent system for identifying parties in financial transactions. Without a valid LEI, your limited company will be unable to execute trades on most major platforms. Getting one is a straightforward process through an authorised Local Operating Unit (LOU) and involves a small annual fee."

Bottom line

Investing surplus business cash can be a powerful strategy for driving long-term company growth. By choosing a platform with low fees and investment options that suit your company’s risk profile, you can transform idle capital into a performing asset.

Remember, your company’s investments are still subject to Corporation Tax, and professional financial advice is highly recommended before starting out.

Frequently asked questions

All investing should be regarded as longer term. The value of your investments can go up and down, and you may get back less than you invest. Past performance is no guarantee of future results. If you’re not sure which investments are right for you, please seek out a financial adviser. Capital at risk.
