How to invest 300k: what should you do with your money?
How you invest 300k hinges on several factors (attitude to risk, long-term financial goals, etc). Find out which route best suits you.
Are you looking to invest £300k?
Keeping large amounts in cash savings often isn’t the best strategy, as inflation can eat into its value and interest rates may be poor.
So, what are your options?
We explore some of the best ways to invest your 300k below.
Identifying your investment goals, risk tolerance, and financial needs is crucial before deciding where to invest £300k.
Investment options include pensions, ISAs, stocks, bonds, and funds, each with varying risk levels and potential returns.
Asset allocation is key—cash for short-term needs, bonds for medium-term stability, and shares for long-term growth.
Consulting a financial adviser ensures informed decisions, effective diversification, and alignment with your personal financial situation and risk appetite.
What are your investment objectives?
Your main priority to identify as you work out where and how to invest your £300k is what you’re hoping to achieve. What is your investment objective?
When working with a financial adviser, your objective will be determined early on in your working relationship based on your financial goals.
To figure it out, they will ask you:
How important is it that your investments are ‘safe’? – How risk-averse are you, and does that priority rank above the desire to maximise your potential profits? Would you prefer to invest in more secure, steady areas?
Would you like to increase your capital as much as possible? – Is growing your wealth more vital to you than instant access to it? Do you have existing savings that will protect you in an emergency?
Are you looking for the best way to invest £300k for passive income? – Is creating a second stream of steady income a priority for you? Are you willing to take on more risk to secure this sort of financial supplement, and are you curious about the potential monthly return on a 300k investment in various scenarios?
Do you want to reduce your tax liability? – Are you concerned with investing in a way that keeps your tax liability low? Would you like your wealth to exist in a form that won’t be taxed where possible?
Are you hoping to focus your investments on retirement/the long-term future? – Do you plan to access your money now, or are you investing for retirement? Are you willing to lock off your money for the long term?
Are there any other financial goals that might impact your objective? – Do you want, for instance, to start a business? Are you gearing up for a big purchase? What else would your adviser need to know?
Which investment products are available?
Once you understand why you’re investing, you can look at where to invest £300k in support of your financial goals and your overarching objective.
You might choose to invest in any of the following:
Your personal pension
Your workplace pension scheme
Stocks and shares ISAs (Individual Savings Accounts)
Stocks and shares (directly)
Investment bonds
Unit trusts and open-ended investment companies
Tracker funds
Investment trusts
The above investment options are either direct or indirect, and in either category, you’ll find no guarantee concerning how your investment will perform. Even the safest investments come with some risk.
Low-risk or 'safe' investments are assets that are less likely to lose any value, making the likelihood of you losing all your money low.
They are also less volatile, so there are unlikely to be big swings in asset value, and they are more liquid, so it’s easier to access your money.

If you want to make your money go as far as possible but don’t know where to start, speaking to an adviser is the best course of action.
Finance professionals are managing over £1.49 trillion in UK-based funds as of October 2024.
This is their area of expertise, and they will be best placed to help you select investments, considering factors you might not and maintaining awareness of things like effective asset allocation.
The importance of effective asset allocation
Whether you’re wondering where to invest £300k now for income or hoping to put your £300k in a fund where the sum can grow over the next ten years, you need to be aware of asset allocation.
In other words, you need to know what category your investments fall under to ensure you’re continually diversifying your portfolio and investing in multiple asset types.
There are three major asset classes (listed in increasing order of risk):
1. Cash (or equivalents)
2. Investment bonds
3. Shares
Cash is your best option if you’ll need access to the money in the next year.
If you’ll need access in the next one to five years, you should choose lower-risk investments, generally staying within the cash and bonds classes.
If you don’t need access for at least five years, shares might instead offer the best return on your investment.
Over 50 years, shares have produced returns of 5.5% a year, while bonds have delivered 2.5%. Over 20 years, the figures are 4.1% for shares and and 3.5% for bonds.
However, it's important to note that shares are generally more volatile than bonds, especially in the short term.

How to invest £300k in your unique financial situation
If every UK resident received £300k tomorrow, financial advice would differ considerably from person to person.
This is because each person would come into their money from a different starting point, and that starting point would be instrumental in identifying the best way to invest £300k.
For example, if you’ve received a lump sum of £300k but don’t have any existing savings, you should keep some of this amount back and create an instantly accessible emergency fund for yourself.
An emergency fund is a way to prepare for unexpected expenses, such as a broken boiler or sudden redundancy, so they don’t knock you off your feet when they arrive.
Try to get to a place where your emergency fund contains enough money to support you financially for at least three to six months, and you’ll be in a good position.
It's also important to consider debt and how it will affect your investment decisions.
The average total debt per UK household, as of November 2024, was £65,777, and the total figure for owed debt across the country was £1,868.1 billion which is up by £3,367 million from £1,864.9 billion at the end of September 2023. This is an extra £562.36 per UK adult over the year.
In most circumstances, you’ll be better off paying your debts before investing, especially when dealing with high interest rates.
Prioritise paying off credit cards and payday loans, clear any overdraft debt, build that emergency fund and then think about how you’d like to invest what remains.
Protecting your investments from tax
If you have a large sum to invest, it’s important to think about the tax implications of your decisions. Some cash savers pay income tax on interest exceeding £500 per year, potentially leading to a big bill.
Likewise, investors in stocks and shares owe dividend tax on dividend income over £500 and could owe capital gains tax when they sell investments.
Using an ISA or pension can be a great way to protect your wealth, as interest, dividends, and capital gains within these accounts are tax-free. You can invest up to £20,000 per tax year in an ISA and up to £60,000 in a pension, subject to income limits.
Given the complexities of tax rules, seeking advice from a financial adviser can help you maximise tax efficiency and avoid potential pitfalls.
How does attitude to risk affect a £300k investment?
As briefly discussed above, your level of risk-averseness could affect your overall objective and shape the sorts of investments that are suitable for you.
The best thing you can do to determine your comfortable level of risk is to speak with a financial adviser and ask for all the information you need to make an informed decision.
No good adviser will push you to do things with your money that you aren’t 100 per cent happy with.
