You can currently earn £100 cashback for opening a Stocks & Shares ISA with Quilter Invest via TopCashback— as long as you fund it with £500 and follow a few simple rules.

At-a-glance

  • Reward: £100 cashback
  • Cash needed: £500
  • Time required:~10 minutes
  • Payout time: Cashback tracked after funding, paid around month 5
  • Risk: Capital at risk if you invest

How to complete the offer

Step 1: Join TopCashback(if you’re not already)
Make sure you’re logged in before clicking through to Quilter Invest — cashback won’t track otherwise.

Step 2: Click through to Quilter Invest from TopCashback
Do not use any other promo or voucher codes unless they’re explicitly listed and approved on TopCashback.

Step 3: Open a new Stocks & Shares ISA
You must be a new Quilter Invest customer to qualify.

Step 4: Fund the ISA with at least £500 (within 30 days)
This is essential. No £500 deposit = no cashback. A member of our Facebook community queried whether a £500+ transfer from another provider would quality and Quilter confirmed it WOULD QUALIFY.

Step 5: Leave the account open and funded
Your balance must not be reduced during the validation period.

When do you get the £100 cashback?

This one isn’t instant — patience required

  • Cashback tracks after funding
  • Validates after 4 months
  • Paid into your TopCashback account in the 5th month

If it doesn’t track automatically, submit a Missing Cashback claim within 100 days.

Do I actually have to invest the £500?

No — you don’t have to invest straight away.

You can leave the £500 sitting as cash within the Stocks & Shares ISA while waiting for cashback to pay out.

That said, a few important things to know:
