Summary Box

Account Name Help to Buy: ISA
What is the interest rate?

Current rates - Effective 14 December 2017

This product pays a variable** rate of interest of:

Tax-free† p.a. AER*
2.25% 2.25%

Whether you need to pay tax is dependent on your own personal circumstances and so may be subject to change in the future.

† Tax-free means that Interest is not subject to income tax.

* AER stands for the Annual Equivalent Rate and shows you what the interest rate would be if interest was paid and added each year. This will enable you to compare more easily the return you can expect from your savings over time.

** Variable rate of interest means that the interest rate payable on your account can change and can move both up and down.

Payment of interest

  • Interest is calculated daily on cleared balances
  • Annual interest is paid on the anniversary of account opening, so if you opened your account on 14th March, interest would be paid on 13th March the following year. It can be paid into the Help to Buy: ISA account, another Chelsea Building Society account or another building society or bank account.
Can Chelsea Building Society change the interest rate?

We can make changes to the interest rate on this account for particular reasons.

General Terms and Conditions (257 KB) 7 and 8 set out those reasons. Term 11 tells you how we will notify you of the changes.

What would be the estimated balance after 12 months based on a £1,200 deposit at account opening and £200 deposited per month?

£1,200 as an initial deposit and £200 each subsequent month saved at 2.25% tax free† p.a./AER* would lead to a balance of £3,451.87 at the end of the first 12 months.

This is provided for illustrative purposes only and does not take into account your individual circumstances.

How do I open and manage my account?

You have to be at least 16 years old. You must be a UK resident for tax purposes, or be a qualifying Crown employee or married to or in a civil partnership with a qualified Crown employee. The account can only be held in your name. You may only subscribe to one cash ISA in a single tax year.

To qualify for a Help to Buy: ISA you must be an “Eligible Customer” as defined in the Scheme Rules but in brief:

  • have a valid National Insurance number
  • be a first time buyer, and never owned a residential property anywhere in the world.
  • only hold one Help to Buy: ISA at any one time and not have previously received a Help to Buy: ISA bonus (unless this has been repaid in full).


For full details of the scheme rules please visit www.helptobuy.gov.uk/isa

Each Help to Buy: ISA account holder can only have one Help to Buy: ISA. If we identify that a second account is held with us this account will be closed and the latest issue e-ISA will be opened with these funds on your behalf.

Account opening and management
Accounts can be opened online at thechelsea.co.uk with a minimum of £10.

You will be able to check your balance, interest rates, view and make your transactions on your account online whenever you wish.

£10 is required to maintain the account after it has been opened.

There is no maximum balance for this account but the maximum amount eligible for a bonus is £12,000.

A maximum of £200 can be saved in each calendar month apart from the first calendar month of account opening when a further £1,000 may be added.

If more than the maximum monthly contribution of £200 is received the funds will be removed and we will return the overpayment by cheque.

The calendar month commences when the first deposit is received to the account and runs from the first to last day of each month. You do not need to save every month or save the same amount every month. If you set up a standing order to pay a monthly contribution, we recommend you set the date prior to the 24th each month to ensure that we receive the funds in time.

Account switching
In accordance with ISA regulations transfers can be made to or from a Help to Buy: ISA.

There are two types of transfer into a Help to Buy: ISA:–

1. A non-Help to Buy: ISA
We will not accept monthly ISA transfers from a Cash ISA into an existing Help to Buy: ISA in order to make the £200 monthly credits. ISA transfers should be for the opening allowance only.

2. From another provider’s Help to Buy: ISA
You remain subject to the maximum monthly deposit limit in the calendar month of transfer. Therefore if you have deposited £200 with your current provider no further deposits can be made in that month. No deposit should be made into the transferred account until we confirm that the transferred funds have been received and credited.

Can I withdraw money?

The Help to Buy: ISA account allows instant withdrawals, without loss of interest. Please note withdrawals and closure will result in the loss of your tax-free status, other than transfers to another ISA. Any withdrawals made will not qualify for the government bonus. This is not a flexible ISA so is subject to subscription limits.

Please be aware if a withdrawal is made from the account by CHAPS a charge of £23.50 will be incurred. Proof of name ID will be required.

Additional Information

Conditions for bonus payment
The bonus is paid by the scheme administrators, on behalf of HM Treasury.

When you are ready to buy your new home you will need to close your Help to Buy: ISA rather than simply withdrawing the balance. Closing the account will generate a Closing Letter. This letter will contain all the information that your conveyancer or solicitor dealing with the purchase of your new home will need to claim the bonus on your behalf.

You must operate your account within the scheme rules. The property you are buying must:

  • be in the UK and be a residential property
  • cost up to £250,000, or up to £450,000 if you are buying in London
  • not be a second home or a buy-to-let property
  • not be rented out after you buy it
  • you must claim your bonus within 12 months of closing your Help to Buy: ISA
  • be purchased with a mortgage. You can chose from a wide range of mortgages that are generally available in the market. If you choose to apply for a mortgage with us, holding a Chelsea Building Society Help to Buy: ISA is not a guarantee that you will be approved for a mortgage with us.


The Help to Buy: ISA can be re-opened if a house purchase falls through and is evidenced within 12 months of the event occurring. Your conveyancer or solicitor will be able to provide a letter of re-instatement to undertake this.

Interest earned from your ISA is tax-free and does not contribute to your Personal Savings Allowance.

If you fail to invest in your Cash ISA in a single year, under HM Revenue and Customs rules you will be required to complete a declaration form before you can invest further.
