How to Open a NatWest Savings Account: Step-by-Step Guide

Opening a savings account is one of the most effective ways to secure your financial future, build an emergency fund, or save for a major milestone. As one of the UK's largest retail banks, National Westminster Bank (NatWest) offers a variety of savings products tailored to different financial goals.

Whether you want an instant-access account for emergencies, a high-yield regular saver to build a monthly habit, or a tax-free Cash ISA, this guide walks you through the exact process of how to open a NatWest savings account. We will cover the specific eligibility requirements, the documentation you will need, and practical tips to ensure your application is approved without delay.

Choosing the Right NatWest Savings Account

Before you begin your application, you must decide which savings product aligns with your financial strategy. NatWest categorizes its savings products into three main pillars: instant access, regular savings, and tax-free ISAs. Selecting the wrong account could mean missing out on higher interest rates or facing unexpected restrictions on withdrawals.

1. NatWest Digital Regular Saver

This is widely considered one of NatWest’s most competitive products. Designed to help people build a sustainable savings habit, it offers a significantly higher interest rate on balances up to a specified limit (typically £5,000), provided you make consistent monthly contributions.

Best for: Individuals looking to save a set amount each month (between £1 and £150) who want to maximize their yield on smaller sums.
Key Restriction: You can only deposit up to £150 per calendar month. Going over this limit requires manual adjustments, and the excess money will be returned to your current account.

2. NatWest Flexible Saver

If you want a safe place to store your money but need the freedom to withdraw it at any moment without penalty, the Flexible Saver is the default choice.

Best for: Storing an emergency fund or short-term savings (e.g., holiday money).
Key Restriction: The interest rate is variable and generally lower than regular savers or fixed-term bonds. However, it offers unlimited, penalty-free withdrawals.

3. NatWest Cash ISAs

A Cash ISA (Individual Savings Account) allows you to earn interest on your savings completely tax-free, up to the annual UK ISA limit (currently £20,000 per tax year).

Best for: Taxpayers who have substantial savings and want to shield their interest earnings from the Personal Savings Allowance (PSA) limits.
Key Restriction: You must be a UK resident aged 18 or over to open a Cash ISA with NatWest (though some junior options exist for minors).

Eligibility Criteria: Who Can Open an Account?

To open a NatWest savings account, you must meet specific criteria. While some savings products are open to brand-new customers, others require you to hold an active NatWest current account first.

Age Requirements: You must be at least 16 years old to open most standard savings accounts (such as the Flexible Saver or Digital Regular Saver). To open an ISA, you must be at least 18 years old.
Residency: You must be a resident of the United Kingdom for tax purposes.
Existing Account Status: To open the high-yield Digital Regular Saver, you must already hold an active NatWest current account (such as the Select, Reward, or Premier account). If you are not yet a NatWest customer, you will need to apply for a current account first or apply for a savings product that is open to new-to-bank customers.

Documents and Information You Must Gather Before Applying

Having your paperwork ready before starting your application will prevent the system from pausing your request or requiring an in-person branch visit.

1. Proof of Identity

You will need one of the following government-issued photo documents:

A valid UK or international passport
A full UK photocard driving licence
An EU/EEA national identity card

2. Proof of Address

If NatWest cannot verify your address automatically through credit reference agencies, you will be asked to upload or present one of the following (usually dated within the last 3 months):

A utility bill (gas, electricity, or water)
A council tax bill for the current year
A bank or building society statement from a different provider

3. Personal Details

Be prepared to provide:

Your full legal name, date of birth, and nationality
Your full address history for the past three years
Your National Insurance (NI) number (mandatory if you are applying for a Cash ISA)
Details of your current employment status and estimated annual income

Step-by-Step Guide: How to Open a NatWest Savings Account

Once you have selected your account and gathered your documents, you can complete the application. The digital route is the fastest and most efficient way to get set up.

Method 1: Applying via the NatWest Mobile App (Fastest for Existing Customers)

If you already hold a current account with NatWest, using the mobile banking app is by far the easiest method. The app already holds your verified identity details, meaning the application can often be approved in under two minutes.

Log In: Open the NatWest Mobile Banking app on your smartphone and enter your passcode, Face ID, or fingerprint.
Navigate to Apply: Tap on the "Apply" tab, typically located in the bottom navigation menu or side drawer.
Select Savings: Choose "Savings" from the product menu to view the available accounts.
Choose Your Account: Select your preferred account (e.g., "Digital Regular Saver") and tap "Apply Now".
Review Terms: Read through the Important Information Document and Interest Rate sheets. Confirm that you accept the terms.
Confirm Details: Verify that your personal information, address, and tax residency status are correct.
Open Account: Tap "Submit". Your new savings account will usually appear on your app home screen instantly, complete with a new account number and sort code.

Method 2: Applying Online via the NatWest Website (For New and Existing Customers)

If you prefer using a desktop browser or do not currently hold an account with NatWest, the website is your primary starting point.

Visit the Savings Page: Go to the official NatWest website and navigate to the "Savings" section.
Compare and Select: Click on the savings account you wish to open and click the "Apply Now" or "New Customer / Existing Customer" button.
Complete the Eligibility Check: The online portal will ask a series of quick questions to ensure you are eligible for the specific product.
Fill in the Application Form: Enter your personal information, contact details, 3-year address history, and employment status.
Identity Verification (IDV): If you are a new customer, you will be prompted to verify your identity digitally. You will need to take a photo of your ID (passport or driving licence) using your smartphone camera and take a short selfie video to prove match-to-ID.
Submit and Wait: Once submitted, NatWest will run automated checks. If successful, you will receive an email confirmation containing your account details within a few minutes to 24 hours.

Method 3: In-Branch Applications

While NatWest encourages customers to use digital channels, you can still open an account in person. This is highly recommended if you have complex tax residency issues, lack a smartphone, or have experienced online verification failures.

Find a Branch: Use the online NatWest branch locator to find your nearest open location.
Book an Appointment: While walk-ins are sometimes accepted, booking a "Savings Review" or "Account Opening" appointment online or by phone ensures a representative is available.
Bring Your Documents: You must bring physical, original copies of your photo ID and proof of address. Photocopies or digital screenshots on your phone are generally not accepted for in-branch verification.
Complete with an Advisor: The banking advisor will input your details, print the terms and conditions for you to sign, and open the account on the spot.

Post-Application: Setting Up and Managing Your Account

Once your NatWest savings account is officially open, there are a few immediate steps you should take to start earning interest and managing your funds effectively.

1. Make Your First Deposit

To keep your account active and start earning interest, transfer funds into your new savings account.

For Existing Customers: Simply perform an internal transfer within the NatWest mobile app from your current account to your new savings account.
For New Customers: Use your existing bank's app to make a Faster Payment bank transfer using your new NatWest sort code and account number. Most transfers complete instantly.

2. Set Up a Standing Order

If you opened a Digital Regular Saver, consistency is key. Set up a monthly standing order from your primary current account to deposit a fixed sum (up to £150) on or shortly after your payday. This automates your savings habit and ensures you don't miss out on high-interest periods.

3. Activate "Round Ups"

NatWest offers a highly practical tool called "Round Ups." When you spend using your NatWest debit card, the transaction amount is rounded up to the nearest pound, and the spare change is automatically swept into your designated savings account.

Example: If you buy a coffee for £2.60, £3.00 is deducted from your current account. The £2.60 goes to the merchant, and the £0.40 change is instantly transferred to your savings account. Over a year, this can add hundreds of pounds to your savings without you feeling the impact on your daily budget.
