Let’s unleash your tax free saving potential. Mix and match your Aldermore Cash ISA products, so you can build the perfect ISA package tailored to your needs.

Best Fixed Rate Cash ISA Provider

What is MaximISA?

Most ISA providers only let you open one cash ISA each tax year, which can restrict your options.

Our MaximISA gives you the freedom, choice and flexibility to maximise your tax free savings plans using different Aldermore Cash ISA products, to make the most of your annual £20,000 ISA allowance in a way that suits you.

You can spread your allowance across the 30 Day Notice Cash ISA and the 1, 2 and 3 Year Fixed Rate Cash ISAs, and, if you’re looking to take the first step on the property ladder, the Help to Buy: ISA where you’ll receive a Government Bonus when you complete on the purchase of your first home.

So now you can look to the future and put your plans in place – in one place.

How does it work?

By opening a 30 Day Notice Cash ISA with any combination of our Fixed Rate Cash ISAs you can maximise your returns across varying maturity dates, and by giving notice still have access to some of your money without penalty. So, for example, you could save £10,000 in our 30 Day Notice Cash ISA and lock £10,000 away in a 3 Year Fixed Rate Cash ISA.

If you don’t have the full allowance available at the start of the tax year, you can save more throughout the year by topping-up or opening further cash ISA products as additional funds become available.

The maximum you can pay into a Help to Buy: ISA each month is £200, so you can combine a Help to Buy: ISA with other cash ISA products to use your full allowance and not lose out.  

And if you’ve got existing ISAs with other providers from previous tax years, these don’t count towards your £20,000 annual allowance so you can transfer these to us in full. By bringing all of your ISAs together in one place, you can manage your ISA portfolio with ease.

Our easy to use MaximISA calculator shows you how much interest you’ll earn and the average interest rate you’ll receive if you spread your ISA allowance across different products.
