Investing platforms have introduced a raft of new tax year cashback offers that give investors the potential to boost their pots by up to £5,000.

This includes cashback from the likes of Charles Stanley Direct*, Interactive Investor*, InvestEngine* and Nutmeg. 

Meanwhile, Hargreaves Lansdown* is offering reduced account fees and Fidelity* is running a prize draw to encourage people to invest.

Now the new tax year is here, you can start putting refreshed tax allowances to good use. 

It’s important to look into your options carefully and choose the best platform for you, rather than picking one solely based on cashback. For example, check the fees to make sure you’re getting a good deal based on the size of your portfolio and how often you want to trade.

You should also consider whether you want to pick your own investments or have a service do it for you. Read our full guide to the best investing platforms and Isas to discover costs and features from the major players.

Who’s offering cashback on Isas and Sipps?

We reveal current Sipp and Isa cashback offers below. You should check when the deals end and when you need to deposit or transfer by. Make sure you register using the relevant sign-up forms and read the terms and conditions of the deal.

Interactive Investor* – cashback for smaller pots

II is offering £100 cashback for new customers who open an Interactive Investor Isa* and transfer or deposit at least £5,000.

It is also offering £250 cashback for Interactive Investor Sipps* for new and existing customers who open and fund a pension with £10,000 minimum. Pension transfers count, too. This cashback’s not available for existing customers who already have an Interactive Investor Sipp.

You should get the cashback into your Interactive Investor account within 30 days of qualifying.

When do you have to act by? The cashback deals end on 30 April 2025, so you have to deposit or request to transfer by then.

This is Money says: If you want to choose your own investments and have smaller amounts to invest, Interactive Investor’s cashback deals are a good option and this is a nice bit of cashback.

Nutmeg – cashback as a percentage of your pot

Nutmeg’s offering 1 per cent cashback on the value of your transfers, across Isas, pensions, Lifetime Isas and Junior Isas.

The minimum you can transfer is £10,000 and you’ll get cashback on the first £500,000, so £5,000 is the most you can receive. Both new customers and existing customers are eligible for the deal. The cashback’s paid into your Nutmeg account.

When do you have to act by? You need to start the transfer by 30 May 2025 and keep your money invested with Nutmeg until 30 May 2026.

This is Money says: If you prefer a service that chooses investments for you, Nutmeg’s cashback looks attractive. And because it’s offering 1 per cent of the amount you invest, it’s a good cashback option for pots of various sizes.

Hargreaves Lansdown* – reduced account fees for six months

This isn’t a cashback offer from Hargreaves Lansdown, but a 40 per cent reduction in fees between July and December means your pot will still get a boost.

You need to open or transfer an Isa or Sipp with at least £10,000 to qualify for the deal.

When do you have to act by? The offer runs from 16 April to 30 June.

This is Money says: Hargreaves Lansdown’s account charge is usually 0.45 per cent for investments up to £250,000, which reduces to 0.27 per cent for six months with this offer. If you have £50,000 you’ll save £45 in fees.

Charles Stanley Direct* – fee waiver on larger pots

You can get up to £1,500 for transferring investments held in Isas and pensions to Charles Stanley Direct. To get the cashback, you have to send Charles Stanley Direct a message titled ‘Cashback’ on its online platform or through its app. 

Cashback is paid into your investment account after you’ve held the transferred investments with Charles Stanley Direct for 12 months.

Move more than £200,000 and you will also get account fees waived for six months. 

When do you have to act by? There isn’t currently a deadline for the offer.

This is Money says: If investors looking for cashback miss out on any time-limited deals, they could check out Charles Stanley Direct. For those transferring larger pots, the platform fee waiver equates to a £300 saving. 

InvestEngine* – lower cashback but fee-free

New and existing customers at InvestEngine* can get up to £4,000 cashback, although you need a large pot to get that amount.

Sipp top-ups and Isa transfers count towards the total deposit for both new customers and existing customers. For new customers, Isa top-ups also count.

InvestEngine says it will pay cashback into its accounts in July.

When do you have to act by? The offer is available on deposits made until 31 May 2025.

This is Money says: This cashback deal is better for people who are new to InvestEngine, because for them both Isa transfers and top-ups count towards the total amount deposited. More cashback is available on lower deposits elsewhere, but unlike other services InvestEngine doesn’t charge platform fees. It’s worth considering for low-cost do-it-yourself investing in Exchange Traded Funds (ETFs). 

Are there any other offers? 

Santander’s offering between £50 and £1,000 in cashback when you invest in its Sipp by either transferring a pension or opening a new one. You have to invest or request to transfer by 25 April 2025. As a high street bank, Santander could be a good option for cashback for those who prefer established names.

Finally Fidelity* is running a prize draw. If you invest £5,000 or more by 31 May 2025, you could win the value of what you invested, up to £20,000.
