How to put money into your account
Don’t worry if you change your mind after you’ve opened your account. If you tell us within 14 calendar days, we’ll give your money back with interest straight away.
AER – stands for Annual Equivalent Rate and illustrates what the interest rate would be if interest was paid and added each year. All rates quoted are correct as at 29/12/2025.
Tax-free – means you will not pay income tax on the interest you earn.
Identification – when you open an account with the West Brom we may need to confirm your identity. For full details on why this is required and the types of identification accepted please refer to the Society’s ‘Important information on identification’ leaflet.
Personal Savings Allowance – the Personal Savings Allowance was introduced on 6 April 2016 and means that the first £1,000 of overall savings interest for basic rate taxpayers and the first £500 for higher rate taxpayers are free from income tax. (There is no allowance for additional rate taxpayers.) From this date, we stopped deducting any tax from the interest paid to you (ISAs are tax-free). You are responsible for paying any tax due to HM Revenue & Customs (HMRC). For further information about the Personal Savings Allowance, please contact your local HMRC office.
Protection for savers – your eligible deposits with the West Brom are protected up to a total of £85,000 by the Financial Services Compensation Scheme, the UK’s deposit guarantee scheme. Any deposits held above the limit are unlikely to be covered. You can visit www.fscs.org.uk for more information.
