Investment Platform

Updated 18 Jan 2026

What is an investment platform?

An investment platform is where you hold your investments. It gives you an account (like an ISA or GIA), lets you buy and sell funds and shares, and keeps everything in one place.

What are some examples of investment platforms?

Hargreaves Lansdown, Interactive Investor, AJ Bell, Vanguard Investor, Fidelity Personal Investing, and Trading 212 are all investment platforms.

How does an investment platform make money?

By charging a platform fee. Some charge a percentage of your portfolio. Some charge a flat monthly fee. Some charge trading fees when you buy or sell.

Is an investment platform the same as a fund provider?

No. The platform holds your investments. The fund provider runs the funds you buy. You pay fees to both.

Some companies do both. Vanguard is a fund provider but also runs its own platform (Vanguard Investor). You can also buy Vanguard funds through other platforms.

Scrimpr’s ISA comparison covers more platforms than any other UK guide.

Quick Heads Up

I'm just one person running Scrimpr, not a big company or financial advisor.

I make these information and comparison pages because I genuinely enjoy researching financial products and helping UK households make informed decisions. But here's what you should know:

  • Not financial advice: I'm sharing information, not telling you what to do with your money
  • Affiliate links: Some links here are referral/affiliate links - I may earn a small commission at no extra cost to you
  • Always check T&Cs: Offers change. Read the full terms on each platform before signing up

Thanks for supporting Scrimpr!
