Does InvestEngine offer the best stocks and shares Isa?

InvestEngine

InvestEngine’s near lack of fees earned it the joint highest score for fees (100%), and its customers scored it above average (76%). Despite a limited asset choice (which scored just 3%), this was enough for it to be named a Which? Recommended Provider and Great Value provider.

‘A good reason to give ETFs a go’

Megan Thomas, Which? investments writer, says:

InvestEngine has been named Which? Recommended Provider for the third year in a row, and picks up another Great Value recognition to go with it.

You can’t get stocks or mutual funds on InvestEngine – only exchange-traded funds (ETFs).

If you want to directly invest in companies, this will be a dealbreaker. But if you were going to invest in funds, ETFs enable you to access the same markets, often with lower fees. And InvestEngine’s relatively large number of them means you can still be diversified by industry, region and asset type.

The only fees you’d pay with InvestEngine are for its managed portfolios, where you don’t choose your investments yourself.

It doesn’t get any cheaper than free so InvestEngine picked up the full five stars for value for money.

Part of the reason InvestEngine can keep costs down is that it processes all of its orders once a day, which can be a downside. This means you might not pay the same price you originally saw when you placed your order for investment in an ETF.

What do customers say about InvestEngine?

InvestEngine customers scored it 76%, the fifth-highest score of any platform in our survey.

Comments from InvestEngine customers that took part in our survey include:

‘Remarkably lower costs than my previous platforms. Additionally, InvestEngine offers speedy customer service, and the website is easy to use. The worst aspect of InvestEngine is the fact that you have to accept the selling or buying price available when it operates at one point mid-afternoon.’
‘The app is excellent, easy to navigate and use. The platform fees are as low as I have found, with no commission on trades. Plenty of helpful guidance and information provided, without being overwhelming. Everything is kept as simple as possible.’
‘It does everything I want, it’s easy to see my investments. Only problem is that it is complicated to withdraw dividends – no automatic withdrawals – which is a pain.’

How we rate stocks and shares Isas

Overall score

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.
