Moneybox investment platform review
Easy-to-use app with no fees for some cash Isa holders
Moneybox is a mobile app that lets you invest with as little as £1 and offers a range of savings and investment products, including stocks and shares Isas, lifetime Isas, and Sipps.
Please note that this article is for information purposes only and does not constitute advice. Please refer to the particular terms and conditions of an investment platform before committing to any financial products.
Does Moneybox offer the best stocks and shares Isa?
Moneybox
Moneybox's customers rated it a well-above-average 75%. But we were disappointed by its relatively pricey fees (scoring them 23%) and limited choice of assets (0%).
This applies to each trade of investments denominated in another currency, for example US stocks, on top of fund and trading charges.
0.45%
Moneybox pays 2.5% interest on uninvested cash held in its stocks and shares Isa.
'Big fees and few choices'
Megan Thomas, Which? investments writer, says:
There are around 60 investments available for you to choose from on Moneybox – one of the smallest selections in our survey. This could be a good thing for you if you find a lot of choices overwhelming, but it will be limiting to any investors with a clearer idea of where they want to put their money.
Moneybox is also lacking on some useful information about investments, such as how a fund or stock has performed relative to the benchmark, while information on the top 10 holdings or asset allocation is only available for Moneybox funds. It picked up just two stars in its customer rating for its information on investments.
The fees on Moneybox are the highest of the brands covered in our survey for amounts over £25,000. But even for investors with less, Moneybox is not the cheapest option.
For the first three months you sign up with Moneybox, you won't pay any of these fees. However, that benefit won't last long and you'd soon have been better off elsewhere.
If you have a cash Isa with Moneybox (with at least £5,000 in it), this won't be a concern, as it will waive the account fees entirely.
Moneybox scored a perfect five stars for ease of use, so if you're happy to pay more for simplicity, it could be a good fit for you.
What do customers say about Moneybox?
Moneybox customers scored it 75%, the eighth-highest score of any platform in our survey.
Comments from Moneybox customers who took part in our survey include:
‘I like to have control of my investments myself. Moneybox enables me to do that. I do find it frustrating that the data and charts for investments are never up to date and that it takes several days for each transaction to go through.'
'I think the app is great and it's easy to invest and manage my stocks and shares ISA. The only negative is that the fees are a little bit higher than other platforms.'
'It was very easy to get up and running. They provided good resources to allow me to decide upon the appropriate level of risk and to manage my fund on a day-to-day basis. Over time I have begun to increase my confidence and investing decisions.'

Is Moneybox safe?
Moneybox is regulated by the Financial Conduct Authority and covered by the Financial Services Compensation Scheme (FSCS).
If Moneybox went bust and its other arrangements to protect your money failed, the FSCS will cover up to £85,000 of investments per person, per platform. You can claim for free online at fscs.org.uk: there's no reason to use a claims management company.
Our overall score is based on a combination of customer score, fees score, and assets score.
We don't analyse the performance of investments listed by investment platforms, as different investors will opt for different investments.
Customer score and ratings
We surveyed 3,053 investors – members of the Which? Connect panel and of the public – who gave 4,146 reviews of stocks and shares Isas in January 2026.
Each platform must get at least 30 responses to receive a customer score, which is based on overall satisfaction and likelihood to recommend.
The customer score makes up 60% of the overall score.
We also ask investors to rate their current platform for customer service, ease of use, information on investments, and value for money.
Fees score
The fees score uses snapshots of account and transaction fees at £5,000, £10,000, £25,000, £50,000, £100,000, £250,000, and £500,000. The fees assume four purchases and four sales in a year, spaced out in across months.
Fees are weighted higher closer to £50,000 as this is close to the average portfolio size, according to HMRC data.
The scores are assigned relative to the cheapest platform which would receive a score of 100%.
The fees score makes up 30% of the overall score.
Assets score
The assets score adds together all of the assets available within a stocks and shares Isa and assigns a score relative to the maximum out of the providers which receives 100%.
The assets score makes up 10% of the overall score.
To be considered to be a Which? Recommended Provider (WRP), the platform needs to have an overall score of 70% or higher.
Companies that reach this score are excluded if they're among the top 25% of the most expensive platforms across our scenarios, based on our fees analysis. Platforms are not eligible for WRP status if they receive a two-star rating or lower in any of our categories.
We also apply statistical tests that place the platforms into ‘bands’. Only the platforms in the highest two bands – the ones that really stand out – can be a WRP.
We will not give Which? Recommended Provider status to platforms that offer CFD trading.
To be eligible for our Great Value recommendation, platforms must be in our top three customer score bands and among the 25% least expensive in the asset categories they offer (any combination of funds, shares, or ETFs).
