THE SHORT ANSWER
Which investment platform is best?
The best platform depends on which account you need and how much you're investing. Low-cost, app-based platforms usually win for smaller or simpler pots, while established full-service platforms suit larger portfolios and hands-on investors. We rate every major UK platform on cost, features and customer reviews, then name Best Buy for each account type.

Investment platform questions, answered
What is an investment platform?
An online service that lets you buy, hold and sell investments - funds, shares and ETFs - in one place. Most let you open a Stocks & Shares ISA, a pension and a Lifetime ISA, and charge a platform fee plus dealing costs.
Which investment platform is cheapest?
It depends on how much you invest and what you hold. Low-cost, app-based platforms tend to be cheapest for smaller or fund-only pots, while flat-fee platforms often work out cheaper once your pot is large. Use the cost filter on each comparison to check against your own amount.
Is my money safe with an investment platform?
UK-regulated platforms are covered by the Financial Services Compensation Scheme (FSCS), which protects eligible investments up to £85,000 per person, per firm if the provider fails. This doesn't protect you from losses if your investments fall in value.
Should I use an ISA or a pension?
An ISA gives tax-free growth and access any time. A pension gives tax relief on contributions but locks money away until at least 55 (57 from 2028). Many people use both - it depends on when you'll need the money.

Historically, money invested for more than five years grows more than cash savings. Remember that investments can also fall, so you might not get all of your money back. Tax treatment depends on individual circumstances and may change.
