Premium Bonds, NS&I, ISAs: Name Change After Marriage UK

A clear guide for UK newlyweds on changing your name on Premium Bonds, NS&I accounts, and ISAs after marriage in 2026. Keep your savings safe.

Congratulations on your marriage! While planning your big day might be over, there's a new 'to-do' list waiting: updating your name on all your important accounts. Among these often overlooked but crucial items are your savings and investments, like Premium Bonds, National Savings & Investments (NS&I) accounts, and Individual Savings Accounts (ISAs). Ensuring your name is correct on these can prevent future headaches and keep your finances in order. We’re here to make this process as straightforward as possible for you.

Why Change Your Name on Savings Accounts?

You might wonder whether it's truly essential to update your name on accounts like Premium Bonds or ISAs immediately. The short answer is yes. Consistency across all your official documents and financial accounts is key. If your name on your savings accounts doesn't match your new married name on your passport, driving licence, or bank accounts, you could face delays or complications when trying to access your money, make withdrawals, or manage your investments in the future. Imagine winning a big Premium Bond prize only to find a hiccup because your name isn't updated – not ideal!

Changing Your Name on Premium Bonds and Other NS&I Products

National Savings & Investments (NS&I) is a popular choice for many, offering Premium Bonds and other savings accounts. Updating your name with them is a relatively simple process. You’ll typically need to send them a copy of your marriage certificate along with a completed change of name form. It’s always best to download the most current form directly from their official website, as requirements can sometimes change.

  • Visit the NS&I website and search for their 'change of name' section.
  • Download and print the relevant form (often called an 'Amendment to personal details' form).
  • Fill out the form carefully, including your old name, new name, NS&I holder number, and signature.
  • Gather a certified copy (or original, if they specify) of your marriage certificate.
  • Post the form and supporting document to the address provided on the NS&I website. Do not send original documents via standard post unless specifically instructed; certified copies are generally safer and accepted.

NS&I usually processes these requests within a few weeks, and they will confirm once the change has been made. Keep a record of what you sent and when.

Updating Your Name on Individual Savings Accounts (ISAs)

ISAs are tax-efficient savings accounts, and you can hold different types (Cash ISA, Stocks & Shares ISA, Lifetime ISA, Innovative Finance ISA) with various providers, such as banks, building societies, or investment platforms. The process for changing your name on an ISA will depend on who holds your account.

First, contact your ISA provider directly. This could be your bank, a specific investment platform, or a building society. They will tell you exactly what documents they need. Typically, you'll need to send them a letter or complete their specific change of name form, along with a certified copy of your marriage certificate. Many providers now allow you to upload documents securely through their online portals, which can speed up the process. Make sure to update all ISAs you hold, not just one.

General Tips for a Smooth Name Change Process

Tackling name changes across all your accounts can feel a bit daunting, but with a structured approach, it's very manageable. Here are some general tips that apply to Premium Bonds, NS&I, ISAs, and beyond:

  • **Start with your marriage certificate:** This is your golden ticket. Obtain several certified copies from the General Register Office (GRO) or the local registry office where you married. Many organisations require a certified copy, not the original.
  • **Prioritise major documents first:** Passport and driving licence are often the first stops, as they are frequently used as proof of ID for other name changes.
  • **Keep a comprehensive list:** Jot down every organisation you need to notify and tick them off as you go. Include account numbers and contact details.
  • **Proof of postage:** If you're sending original or certified documents by post, use recorded delivery or a similar service that provides proof of postage and delivery.
  • **Be patient:** Some organisations process name changes faster than others. Allow a few weeks for changes to be reflected, especially during busy periods.

Updating your name on your Premium Bonds, NS&I accounts, and ISAs is a vital step in securing your financial future under your new married name. It might require a little effort now, but it will save you considerable hassle down the line. Take it one step at a time, gather your documents, and you'll have everything updated smoothly.
