Plum Review – Is ‘AI’ the best way to save and invest?

Plum review - Is AI the best way to save and invest?

Building up a savings pot and putting away a regular amount each month is something that most Britons find difficult and this is proven by the fact that almost 50% of the UK has savings of less than £1,500. Living standards have been hit in recent years due to weak wage growth and rising prices, making the difficult task of saving money even harder.

There are many ways to start saving and investing, but what is the best way and how can you get started?

What is Plum and how does it work?

Plum* is a savings and investment 'robot' for your phone that analyses your spending and automatically saves your money for you, so you don't have to. Plum decided to make saving money seem less of a chore and easier by allowing us to spend on 'things we want, rather than things we need'. Originally Plum worked using a Facebook messenger chatbot but has since developed into stand-alone iOS and Android apps.

Plum was founded by Victor and Alex, two Cypriots living and working in the UK, who decided to challenge each other to save. This, in turn, resulted in Alex coming up with an algorithm that monitored his spending, putting aside the amount he could afford to save each month. This process allowed him to automate the savings process without having to alter his spending habits.

Plum works by linking to your bank account (it supports all major UK banks) and analyses your spending and transactions to work out the best amount to put away every week. You determine how much you want Plum to save and can ask it to stop saving at any time. To sign up to Plum you need to be a UK resident and have a UK current bank account.

With Plum not only do you have the opportunity to build up a savings pot, but you can also invest your savings for a small monthly fee.

Saving with Plum

Plum* helps you to save by using its algorithm and artificial intelligence to analyse your spending to save you money automatically. You can decide how much money you save with Plum based on the moods shown in the image below as per Plum's website (the standard saving setting for Plum is 'Normal'):

Plum Saving


You can change your mood in the app or via the 'Brain' section of the app. Plum will analyse your spending and move its calculated savings amount to your Plum account every 4-5 days. If you want to withdraw money from your Plum account you can also do this via the app. If you request to withdraw money from your instant access primary pocket it should be in your bank account within 30 minutes. If you request to withdraw money from an interest pocket before 3pm you are likely to receive it the same day, however if you request to withdraw money after 3pm you may not receive it until the next working day. All of Plum's accounts allow you to take advantage of its clever saving algorithm that allows you to save automatically. However, if you wish to set savings goals or take part in the 52-day and Rainy day challenges you will need to upgrade to a Plum Pro or Ultra account.

Where are my savings kept?

Funds are kept in 'pockets' and you can choose between a 'primary pocket' which provides instant access to your money or an 'easy-access pocket' where you'll need to provide 1 day's notice in order to access your savings. Primary pockets do not pay any interest and the money is held as e-money with Plum and so is not protected by the Financial Services Compensation Scheme (FSCS). The Plum Easy-Access pockets are provided by Investec and pay up to 1.01% interest (depending on the Plum plan you are on). Plum's Easy Access accounts are protected by the FSCS.

We provide a useful table below which explains which pockets are available, as well as the main features.

Plum Primary pocket Plum Easy Access Savings (Basic accounts)  Plum Easy Access Savings (Plus, Pro and Ultra accounts) 
Plum account cost (monthly)  Free Free £1/£2.99/£4.99
Interest paid 0.00% 0.50% 1.01%
Instant Access tick cross cross
Notice Required* No notice required 1 day 1 day
FSCS protection cross tick tick

*If requested before 3pm on business days it may be completed the same day

Investing with Plum

You can invest in a Stocks and Shares ISA or a General Investment account with Plum from as little as £1. Set how much you want to invest and Plum will automatically do this for you. With a Plum investment account, you can deposit and withdraw money as little or as often as you would like (withdrawals can take between 5-7 working days). Bear in mind that your capital is at risk when investing.

Invest with Plum

Plum provides a choice of 12 funds that you can invest in with varying levels of risk as shown below. These are provided by a number of third-party investment houses and include the extremely popular Vanguard Lifestrategy fund range. The table below shows the investment type alongside the current 5-year total return. Where the number is green it means that the fund outperformed the average of its peer group. Where it is red it means that it underperformed. A "n/a" means that the fund has not been in existence for five years. The latest performance figures and yearly breakdowns for each fund can be found on the Plum website.

Investment type 5-year return  Risk level 
Tech Giants Technology shares 135.25% High
Clean & Green Socially responsible companies 5.94% Medium
Balanced Ethical  Diverse asset mix based on ESG criteria N/A Medium
Growth Ethical  Shares of global companies selected for ESG track record N/A Medium
Rising Stars New companies in Asia & Africa 31.45% Medium

Remember: You can hold as many stocks and shares ISAs as you like across multiple providers, however, you can only contribute the current tax-year allowance into one stocks and shares ISA with one provider and so make sure you check before you commit to a PlumISA

Plum Self-invested Personal Pension (SIPP)

Plum recently launched a Self-invested Personal Pension (SIPP) to help you to prepare for retirement. The Plum SIPP is provided by Gaudi Regulated Services Ltd and is covered by the Financial Services Compensation Scheme (FSCS). You can choose to consolidate existing pensions into a Plum SIPP or start a new Plum Pension altogether. Whilst Plum lets you save into a pension it does not currently allow you to draw an income - often referred to as pension drawdown - and so you would need to transfer your Plum SIPP to another provider when you want to access your money.

You can contribute to a Plum Pension via regular contributions from your Plum auto-savings that can be increased or reduced to suit your budget. You can also make one-off contributions to the Plum pension from your connected bank account or your Plum Balance.

When investing in the Plum SIPP you can choose from three investment fund types:

  • Target Retirement Date Fund - this fund changes what it invests as you approach retirement age starting with higher-risk investments and changing to lower-risk investments as you near your retirement date. The funds are provided by Vanguard.
  • Global Growth - this fund invests in a range of worldwide company shares and is provided by Legal & General.
  • Future Planet - according to Plum this fund invests in 'shares of companies that meet positive carbon and environmental criteria' and it is provided by Legal & General.

Should I invest with Plum?

It is important to remember that any type of investing comes with a certain level of risk meaning it is possible to get back less than you put in.

If you invest in tech and growth funds with Plum your money is held in an investment account with Gaudi Regulated Services LTD, which is FCA regulated and your money is FSCS protected. If you invest in other funds with Plum you also have FSCS protection.

Plum Card

Plum is in the process of launching a prepaid visa debit card that users will be able to request within the app. Users will be able to load money onto the card from your Plum Primary Pocket or linked bank account but the card will not be protected by the FSCS as the Plum Card is an e-money product. Once you have ordered your Plum card it can take up to 10 working days for the card to arrive and it is dispatched by Royal Mail. The Plum card can be used anywhere that Visa is accepted and it can also be used to spend abroad fee-free with Plum only charging you the Visa exchange rate.

According to the Plum website, the Plum Card will only be available to Plum Ultra subscribers which comes at a monthly cost of £4.99 and it is currently only being offered to a select few customers to be tested. We will update the review with more information on the Plum card once it becomes available. If you are looking at other prepaid debit cards or ways to spend money abroad fee-free check out our article, 'The best app-only bank in the UK'.

How much does Plum cost?

The cost of Plum varies depending on the account you choose. The most basic version of Plum is free and allows you to take advantage of the AI savings features. However, if you want to benefit from more budgeting features or you would like to invest you will need to upgrade to either Plum Plus, Pro or Ultra at £1, £2.99 or £4.99 a month.

How much does it cost to invest with Plum?

If you choose to invest with Plum you will need to pay a minimum of £1 for the Plum Plus account. There is also an annual fund management and product provider fee which is on average 0.48%. This consists of a product provider fee of 0.15% and a fund management fee that ranges between 0.06%-0.90%.

Plum SIPP fees

The fee for a Plum SIPP is 0.45% a year which is broken down into a 0.35% administration charge and a 0.10% custody service charge. The fee is payable at the end of the month and is deducted from your Plum SIPP balance. In addition, a fund management fee is charged, ranging from 0.24% - 0.30%, depending on the fund you choose to invest in.

Is Plum safe to use?

Plum is authorised and regulated by the Financial Conduct Authority to carry out payment services activities as a Registered Account Information Service Provider, under the Payment Services Regulations 2017.

If you choose to hold your money in an instant-access primary pocket then it is held as e-money. Plum uses an e-money provider that maintains a specific UK bank account and so it says your money is protected by the E-Money Safeguarding Rules. It is important to note that money held in an instant-access primary pocket or on a Plum Card is not protected by the Financial Services Compensation Scheme (FSCS).

However, if you choose to hold your money in an easy-access pocket or with an investment account, then your money is protected by the Financial Services Compensation Scheme (FSCS).

Alternatives to Plum

Plum vs App-only banks

Monzo and Starling Bank are app-only banks that can help you to save with round-up spending. When you spend with Monzo and Starling you can opt to round up your change, putting it into a savings pot. By setting up automatic saving you save every time you spend and while it may not seem like much, it quickly adds up.

For more information read our reviews of Monzo and Starling Bank.

Plum vs Chip

Chip allows you to save automatically by using open banking to analyse your spending habits. Chip works in a similar way to Plum in that it saves your money for you and moves it into your Chip account. You can also choose to invest with a ChipX account but this comes with a £3 fee every 28 days.

Like Monzo and Starling Bank you can set savings goals and track your progress to achieving those goals. Chip is FCA regulated and your savings are stored with partner banks and are therefore FSCS protected.

For more information on Chip, read our Chip review.

Plum vs Moneybox

Moneybox is another savings app that allows you to invest the money you put away. Moneybox helps you to save by rounding up your spare change and you can invest the money you save into a variety of savings products such as a Stocks and Shares ISA, Stocks and Shares Lifetime ISA, Pension, Junior ISA, General Investment Account, Socially Responsible Account, Cash Lifetime ISA, Simple saver or 32, 45, 95 or 120-day notice account.
