Checked By Richard Berry
Updated July 15, 2025

Even though UK interest rates have recently been reduced to 4.25%, you can still get some investing accounts will pay you interest on your cash of up to 5% to encourage you to keep it with them, rather than transfer it out to higher-paying interest bank accounts.

We have ranked and compared UK trading platforms and investing accounts that offer the highest interest on uninvested cash balances.

Sort by:

Name	Cash Interest	Min required	GMG Rating	Customer Reviews	CTA	Feature	Expand
IG	Cash Interest 4.25%	Min required £1	GMG Rating (5)	Customer Reviews 3.9 (Based on 678 reviews)	See Offer Capital at risk	Features: DIY Managed FCA Regulated FSCS Protected	More Info IG pays interest on uninvested GBP up to £100,000 in a GIA, SIPP or ISA account. Unfortunately, you don’t earn interest on CFD or spread betting accounts so you will have to move your money across to earn on cash. I suspect this will change in the future, as IG cross-sells investment and trading products. Also, unlike other brokers, you have to be an active investor to receive interest, so you cannot treat it like a bank account and just leave your cash there without doing anything.
interactive investor	Cash Interest 3.25% – 1%	Min required £1	GMG Rating (5)	Customer Reviews 4.3 (Based on 1,119 reviews)	See Offer Capital at risk	Features: DIY FCA Regulated FSCS Protected	More Info As with all Interactive Investor pricing structures, they are a little complex, as a lot of it is scaled and dependent on what type of account you have. For ii’s ISA, Junior ISA, and trading accounts, cash balances will receive a certain amount of interest on the first £10,000, then more on the value between £10,000 and £100,000. If you’ve got a very big account with over £1m, you can receive the best rate.
Investengine	Cash Interest 0%	Min required £0	GMG Rating (4.5)	Customer Reviews 4.8 (Based on 1,616 reviews)	See Offer Capital at risk	Features: DIY Managed FCA Regulated FSCS Protected	More Info InvestEngine does not offer interest on uninvested cash.
Lightyear	Cash Interest 4.34%	Min required £1	GMG Rating (4.2)	Customer Reviews 4.8 (Based on 275 reviews)	See Offer Capital at risk	Features: DIY FCA Regulated FSCS Protected	More Info Lightyear does not offer interest on uninvested cash instead, customers can earn money on cash by allocating their money to Vaults, or money market funds, which are managed by BlackRock. Money market funds are treated as investments and, as such, do not receive the standard Financial Services Compensation Scheme (FSCS) guarantee on balances up to £85,000 should they fail and lose money. It is rare for a money market fund to fail, but it could still happen, particularly in conditions of extreme market volatility.
Wealthify	Cash Interest 0%	Min required £0	GMG Rating (5)	Customer Reviews 4.6 (Based on 2,564 reviews)	See Offer Capital at risk	Features: Managed FCA Regulated FSCS Protected	More Info Wealthify does not offer interest on uninvested cash.
Interactive Brokers	Cash Interest 4.05% – 0%	Min required £8k	GMG Rating (5)	Customer Reviews 4.4 (Based on 934 reviews)	See Offer Capital at risk	Features: DIY FCA Regulated FSCS Protected	More Info IBKR offers good interest on uninvested cash, but you only get the full amount if you have over £100k on account, including cash and investment. It is not great for small accounts, though, as there is no interest payable on balances and portfolios below £8k.
Moneyfarm	Cash Interest 0%	Min required £0	GMG Rating (5)	Customer Reviews 4.4 (Based on 235 reviews)	See Offer Capital at risk	Features: DIY Managed FCA Regulated FSCS Protected	More Info Moneyfarm does not offer interest on uninvested cash.
AJ Bell	Cash Interest 4% – 1.55%	Min required £1	GMG Rating (5)	Customer Reviews 4.2 (Based on 1,094 reviews)	See Offer Capital at risk	Features: DIY FCA Regulated FSCS Protected	More Info AJ Bell pays fairly high interest on cash balances for their SIPP and Junior SIPP accounts. For stocks and shares ISAs, the maximum interest is higher than with share dealing accounts where interest rate payments are paid quarterly, and they are scaled. For example, if you had £50,000 cash in an AJ Bell account, £10,000 of this money would earn the ‘£0–£10,000’ interest rate, while the remaining £40,000 would earn the ‘Above £10,000’ interest rate. You can’t combine your SIPP and ISA balances to get better interest rates, as they are charged separately.
Hargreaves Lansdown	Cash Interest 3.15% – 1.75%	Min required £1	GMG Rating (5)	Customer Reviews 3.8 (Based on 1,758 reviews)	See Offer Capital at risk	Features: DIY FCA Regulated FSCS Protected	More Info Hargreaves Lansdown has increased interest rates on its accounts, bringing it further in line with competitors. Among its accounts, the platform’s SIPP offers the best rate for uninvested cash followed by their ISA, then general investing account.
Saxo	Cash Interest 2% – 1.5%	Min required £5k	GMG Rating (5)	Customer Reviews 3.6 (Based on 73 reviews)	See Offer Capital at risk	Features: DIY FCA Regulated FSCS Protected	More Info Saxo has considerabley dropped it’s rates from the 1st of May and now only pays a fixed rate on interest on balances over £5,000. To get their top interest on cash, you need between £1m and £2m in a VIP account.
Dodl	Cash Interest 4.25%	Min required £1	GMG Rating (4.3)	Customer Reviews 4.5 (Based on 38 reviews)	See Offer Capital at risk	Features: FCA Regulated FSCS Protected	More Info The ISA and Lifetime ISA on AJ Bell’s Dodl simplified investment app offer one of the best interest rates among competitors. However, Dodl does not offer interest on uninvested cash in a general investment account or SIPP (pension).
CMC Invest	Cash Interest 2%	Min required £1	GMG Rating (4.4)	Customer Reviews 4.1 (Based on 14 reviews)	See Offer Capital at risk	Features: DIY FCA Regulated FSCS Protected	More Info CMC Invest offers customers a 2% gross interest rate (2.02% AER) on all uninvested, settled cash held across any of its investment accounts, including General Investment Accounts (GIA), Cash ISAs, Flexible Stocks & Shares ISAs, and SIPPs.

eToro	Cash Interest 4.30% – 1.5%	Min required $10k	GMG Rating (4.6)	Customer Reviews 3.4 (Based on 277 reviews)	See Offer Capital at risk	Features: DIY Managed FCA Regulated FSCS Protected	More Info To get interest in the UK on your free cash balance with eToro, you need a minimum balance of $10,000. The level of interest paid then scales according to a customer’s Club Tier, which is determined by how much money users keep in their account.

Freetrade	Cash Interest 5% (Plus) – 0%	Min required £1	GMG Rating (4.1)	Customer Reviews 4.6 (Based on 1,336 reviews)	See Offer Capital at risk	Features: DIY Managed FCA Regulated FSCS Protected	More Info Freetrade offers it’s maximum interest on up to £3,000 in uninvested cash under its Plus account subscription plan, which charges £9.99 a month.

Which brokers and investment platforms pay the most interest on uninvested cash?

Freetrade currently offers the most interest on uninvested cash at 5%, but you need to have a Plus subscription to get it.

Other platforms, including, IG, Interactive Brokers, Interactive Investor and Hargreaves Lansdown, also pay competitive interest rates, but these are tiered according to account balances.

Interest rates have been declining across the board, but you can still get some pretty decent returns with these investment accounts.
