Gert Svaiko

If you’re saving towards buying a home in the UK, a Help to Buy ISA could be a very useful product for you.

But what actually is a Help to Buy ISA, and who’s eligible to open one? We’ll cover everything you need to know here in this guide, including the rules, how to open one and those all-important interest rates.

What is a Help to Buy Individual Savings Account (ISA)?

A Help to Buy ISA is a government-run scheme aimed at people wanting to buy a home in the UK. Crucially, it’s only for first-time buyers, to help them save towards a mortgage deposit.

Like other types of ISA products, the Help to Buy ISA offers tax-free savings up to your personal allowance. Accounts offer interest rates, as well as tax-free bonus on your savings provided by the government.

Unfortunately, you can no longer open a new Help to Buy ISA in the UK. But if you already have one, you can continue to save into it and receive the government bonus.¹

How does a Help to Buy ISA work?

A Help to Buy ISA works just like an ordinary savings account, but with one key difference. You’ll open an account and deposit funds, but the government will top up your contributions with an extra bonus - up to a limit. This helps your savings grow faster. On top of this, Help to Buy ISAs also offer interest on your balance.

There are a few strings attached though. You’ll only be able to pay in up to £200 a month, and you’ll need to save at least £1,600 in order to receive the government bonus. The maximum you can save in a Help to Buy ISA is £12,000.¹

You’ll only get the government bonus when you buy your property, and need to hand over the deposit. Once your offer on a property has been accepted, you’ll need to ask your conveyancer to apply for the bonus.

How much is the state-added bonus?

The government bonus for Help to Buy ISAs is 25%.¹ Here’s a look at how much this works out as, depending on how much you save:¹

SavingsGovernment bonus
£200 (the monthly max. you can save)£50
£1,600 (the min. savings to get the bonus)£400
£4,800£1,200
£12,000 (max. you can save in a Help to Buy ISA)£3,000

What are the rules for qualifying for Help to Buy ISAs?

The Help to Buy ISA rules are a little strict, but it could be worth it to help you save for a deposit - which can be difficult while renting a home at the same time.

To be eligible, you’ll need to be:¹

  • Living in the UK and buying a home there
  • At least 16 years old
  • A first-time buyer, who doesn’t already own a property
  • Buying your property with a mortgage
  • Buying a home worth up to £250,000 (or up to £450,000 if in London)
  • Planning to live in the property, not rent it out.

What are the interest rates for Help to Buy ISAs?

As you can no longer apply for a Help to Buy ISA, not many providers have products available.

Here are just a handful of UK banks that are still advertising their Help to Buy interest rates, which are expressed as AER variable. This stands for Annual Equivalent Rate, and shows you how much you’ll earn over the course of a whole year. Variable means that the rate can change at any time.

Bank name and ISAAER on £1-£12,000AER on £12,000+
HSBC Help to Buy ISA²2.75%1.30%
Halifax Help to Buy ISA³2%0.70%
Lloyds Help to Buy ISA⁴2.45%0.85%
Barclays Help to Buy ISA⁵2.02%2.02%

Withdrawing and closing your Help to Buy ISA

With Help to Buy ISAs, withdrawals are possible, and even unlimited with some providers.⁴ But bear in mind that you won’t get the government bonus on anything you take out.

When you want to buy your home and use your savings (and bonus) for your deposit, you’ll need to close your account. Then, you can claim your bonus through your conveyancer.

If you close your ISA and transfer it to another non-ISA savings account, you’ll lose the tax-free status on your savings.
