Our take

Hargreaves Lansdown is the UK's number one investment platform for private investors, trusted by 2M people to help manage their money. Founded back in 1981 in a spare bedroom, it's grown into a powerhouse, and with more than £170B in assets under its administration, it's become the biggest name in DIY investing in the country.

The company offers a wide range of services that include Stocks and Shares ISAs, pensions (SIPPs), savings accounts, and a market-leading investment app, making it easy for everyday people to invest, save, and better plan for their retirement.

Recently, HL was taken private in a £5.4B deal, with new leadership aiming to modernise and future-proof the business. And despite more competition from digital challengers, it continues to thrive, adding more customers, launching new features, and paying strong dividends. On top of that, it's got over 40 years of experience and a forward-thinking team driving it towards even more success.
