2. – Low-Cost Broker With 4,000+ Commission-Free Markets review

If you’re want to allocate some of your £100k investment funds into short-term trading strategies, is a good option. This online broker gives you access to contracts-for-differences – or CFDs. These are financial instruments that track asset prices in real-time, meaning that you can gain exposure to your chosen market without owning anything. For example, if the global spot price of gold is $1,700 per oz, you need to determine whether the price will rise or fall.

When you trade assets in this way, you can apply leverage to your positions. If you are a UK retail client, leverage limits are capped at 1:30, albeit, this will depend on the asset. For instance, major currencies can be traded with leverage of 1:30 and stocks at 1:5. By trading CFDs at, you can also engage in short-selling positions. For example, you might look at Apple stocks and think that they are overvalued – so you would simply need to place a sell order to try and profit from this. review

  • Tight spreads and no fee on deposits or withdrawals
  • Supports thousands of financial markets
  • Convenient for newbies


  • Experienced traders might consider the broker too basic
  • £250 minimum deposit on bank transfers

Step 2: Best Way to Invest £100k  – Choose an Investment

When thinking about the best ways to invest £100k, you should draw up a shortlist of asset classes that are suitable for your risk profile. It goes without saying that the higher the returns that you seek, the more risk you should be prepared to take. This is why it is best to create a diversified portfolio across dozens of different markets, as this will help balance out the risk of each asset. 

We have narrowed down our list of the best ways to invest £100k in the UK to just five options – which you can read about in the sections below.  

Growth Industries – Overall Best Way to Invest £100k in the UK

With an investment of £100k, you can build a portfolio of stocks that focus on industries of the future. In doing so, you stand the chance to invest in companies that are involved in innovative products and services that could one day shape the way in which society lives. As a prime example, electric vehicles are sure to play a major part in the future of transportation. In order to gain access to this market, you might consider buying shares in firms such as Tesla or Nio.

vanguard growth etf

You then have the emergence of blockchain technology and digital currencies, so a stock like Coinbase would be ideal for this purpose. Alternatively, you might even consider investing in an ETF that specifically targets growth industries. One such example is the Vanguard Growth ETF, which consists of over 285 growth stocks from a wide range of industries and sectors. Either way, by backing stocks and ETFs that target growing niches, you can invest at a highly favorable price by getting in early.

Invest in Growth Industries Pros

  • Invest in up-and-coming companies
  • Gain exposure to new and exiting technologies
  • By investing early you will get a highly favorable entry price
  • You can invest in growth industries via an ETF
  • Potential to earn above-average market gains

Invest in Growth Industries Cons

Blue-Chip Stocks – Invest £100k into a Basket of Blue-Chip Stocks

While growth companies allow you to invest in new and exciting sectors and industries, blue-chip stocks will provide your portfolio with a lot more in the way of stability. This is because, in the vast majority of cases, blue-chips refer to firms that have not only been trading for many decades, but they dominate their respective sector. This means that you will be investing in companies with a long-standing track record on the stock market and oftentimes – pay regular dividends.

dow jones etf

Some of the most recognized blue-chip stocks in the UK include British American Tobacco, AstraZeneca, HSBC, Unilever, and BP. Over in the US, popular blue-chip stock investments include Mircosoft, Apple, IBM, Johnson & Johnson, and Procter & Gamble. Perhaps the best way to gain access to a basket of blue-chip stocks is to invest in the Dow Jones Industrial Average via an ETF. This will mean indirectly buying all 30 blue-chip stocks that contribute to the Dow Jones – but through a single investment.

Blue-Chip Stocks Pros

  • Invest in strong and stable companies
  • Most blue-chips have been operational for many decades
  • Add some stability to your portfolio
  • Many blue-chip stocks pay regular dividends
  • Less risk in comparison to growth stocks

Blue-Chip Stocks Cons

  • Returns will be more modest
  • Not all blue-chip stocks pay dividends

Index Funds – Diversify Your £100k Investment via Stock Index Funds

Index funds are typically offered by ETF providers like SPDR, Vanguard, and iShares. The main concept here is that the index fund will track a pre-defined marketplace, which the ETF will look to mirror like-for-like. Let’s take the S&P 500 as a prime example. This stock market index fund will track 500 top-performing companies that are either listed on the NYSE or NASDAQ. This will include the likes of Apple, Microsoft, Facebook, Tesla, Disney, Coca-Cola, and Pepsi.

nasdaq 100 inex fund

Each index fund will be weighted so that it aligns with the respective market as best as possible. For instance, while Microsoft contributes about 6% to the S&P 500, Visa is weighted at just 1%. There are dozens of other stock index funds that you might consider for your portfolios – such as those that track the FTSE 100, AIM, Dow Jones, NASDAQ 100, or the EURO STOXX 50.  Once you complete your index fund investment, you will be entitled to your share of any dividends that the ETF provider receives.

Stock Index Funds Pros

  • Invest in hundreds of companies through a single index fund trade
  • Dozens of leading stock index funds to choose from
  • Passive investment stream
  • The ETF provider will regularly rebalance the index fund portfolio
  • You will be entitled to your share of any dividends received

Stock Index Funds Cons

  • Your index fund investment will decline when the stock markets are down
  • You might be missing out on more attractive gains

Bonds – Invest £100k into Corporate and Government Bonds

Bonds are attractive to those that seek predictable income flows. This is because – in the vast majority of cases, bonds pay a fixed rate of interest. This means that as long as you hold onto the bond instrument until it expires, you will know exactly how much you will make. In terms of risk and potential rewards, this will ultimately depend on the bond that you decide to buy. For example, you have bonds issued by the US (Treasuries) and UK (Gilts) governments, which attract an annual coupon yield in the region of 1-2%.

bond etf etoro

This is because the risks of investing in these bond types are virtually non-existent. On the other hand, if you were to invest in corporate bonds, the risks are much higher. This is because companies do not have the backing of a central bank or government. In turn, the coupon yields available on corporate bonds will be more attractive. With that said, it might be best to invest £100k in a bond ETF. In many cases, this will give you access to thousands of government and corporate bonds with various risk ratings and maturity dates.

Stock Index Funds Pros

  • Bonds offer a predictable flow of income
  • Most bonds offer fixed-rate yields
  • Government bonds issued by the UK and US are virtually risk-free
  • Corporate bonds often come with an attractive yield 
  • Completely passive – no need to do anything once you have invested  

Stock Index Funds Cons

  • Government and high-grade corporate bonds pay very low yields
  • You always face the risk of the bond issuer defaulting on a payment

REIT – Invest £100k into the UK or International Real Estate Industry

If you’re looking to invest £100k into the UK real estate market, this likely won’t be enough to get your foot on the property ladder. You can, however, consider investing some of your £100k into a REIT (Real Estate Investment Trust). Your chosen REIT will collect funds from thousands of investors – much like any other ETF or mutual fund. In doing so, the REIT will purchase real estate holdings on behalf of its investors. Then, any capital gains appreciation on the properties will be reflected in the REIT share price.


Furthermore, and perhaps most importantly, REITs collect rental payments from tenants. As an investor, you would be entitled to your share of the proceeds after fees. Ultimately, REITs allow you to invest in the UK and international real estate markets without directly owning properties. And, as the REIT provider will find, manage, and replace tenants, you will be investing in a 100% manner. Some of the sectors that REITs cover include commercial buildings, residential units, multi-family complexes, shopping malls, and healthcare facilities.

REITs Pros

  • Invest in properties without needing to own anything directly
  • Hundreds of REITs to choose from
  • REITs cover residential units, business offices, shopping malls, and more
  • Earn your share of any rental payments after fees
  • 100% passive – no need to manage tenants or collect payments  

REITs Cons

  • Fees are much higher than stock index funds
  • Returns are more modest than other asset classes
