Leeds Building Society: Savings, Mortgages & Account Help

Leeds Building Society customers usually need one of a few practical things: compare a savings account, manage an ISA, log in to an online savings account, deal with a maturing account, apply for or manage a mortgage, change personal details, find a branch or speak to the correct support team.

This page is organised around those real tasks. It explains which Leeds Building Society service to use, what to prepare before contacting the Society, and where account rules differ between online savings, branch accounts and mortgages.

Independent website and account-safety notice: Building-society.org is not Leeds Building Society. We cannot access your savings, mortgage, online account, statements or security details. Never enter your password, memorable answers, one-time passcode or full financial information on this website.

Meaningful editorial review: 13 September 2026. Savings rates, mortgage deals, cashback offers, branch opening arrangements and product conditions can change. Check the live Leeds Building Society page before applying or moving money.

What Leeds Building Society Does

Leeds Building Society is a mutual rather than a shareholder-owned bank. Its core business is helping members save and helping borrowers buy homes through residential and specialist mortgage lending.

The Society was established in 1875 and remains member-owned. Its 2025 annual reporting recorded more than one million members, total assets of about £32 billion and 51 branches across the UK.

Savings Cash ISAs, fixed-rate bonds, easy-access accounts, online savings, regular savers and children’s accounts.
Mortgages Home purchase, remortgage and existing-customer mortgage services, subject to lending criteria.
Member-owned As a mutual, Leeds Building Society is owned by its members rather than external shareholders.
Service channels Depending on the product, members may use online services, telephone support, post or a branch.
Building society does not mean every product is automatically best. Compare rates, restrictions, fees, access and service against other suitable providers before opening a savings account or choosing a mortgage.

Leeds Building Society Savings Accounts

The right Leeds savings account depends mainly on three things: how quickly you need your money, whether you want a fixed or variable rate, and whether ISA tax treatment matters.

Savings type
May suit you when
Check before opening
Cash ISA
You want eligible savings interest to remain tax-free under ISA rules.
ISA allowance, transfer rules, withdrawal conditions and whether the rate is fixed or variable.
Fixed-rate bond
You can leave a lump sum untouched for an agreed period.
Term, maturity date, access restrictions, minimum deposit and funding deadline.
Online savings
You are comfortable managing the account digitally.
Minimum balance, nominated account rules and whether withdrawals are unlimited.
Easy access
You may need to withdraw without committing to a fixed term.
Rate tiers, withdrawal method, cash limits and whether branch or postal management is required.
Regular saver
You want to build savings gradually through regular deposits.
Monthly funding limits, withdrawal rules and what happens at maturity.
Children’s savings
You are saving for a child or managing eligible children’s money.
Age limits, control of the account, withdrawal authority and account-opening requirements.
Rates can change quickly. Do not rely on a rate copied into an older comparison page or search result. Leeds Building Society maintains a live savings comparison page showing the current product issue, rate, minimum opening balance and withdrawal rules.

Leeds Building Society Cash ISAs and ISA Transfers

Leeds Building Society offers fixed and variable Cash ISAs. Its current ISA information states that eligible customers can subscribe up to the applicable annual ISA allowance for the tax year and may also be able to transfer ISA money from earlier tax years.

Fixed-rate Cash ISA

  • Useful when you want a known rate for a fixed period.
  • Check the interest penalty for withdrawing before maturity.
  • Check the funding deadline for the specific issue.
  • Confirm what account the money moves to at maturity.

Variable-access Cash ISA

  • May suit customers wanting more access to their savings.
  • The interest rate can change.
  • Check whether the ISA is flexible before withdrawing and replacing money.
  • Check whether it is online-only, branch-managed or postal.
ISA transfer mistake to avoid: if you want to preserve the ISA status of existing savings, use the receiving provider’s formal ISA transfer process rather than simply withdrawing the money into an ordinary account.

Leeds Building Society Online Account Login and Registration

Leeds Building Society has been moving existing online customers from logging in with a 10-digit customer number to a username and password. If you previously used a customer number, the official service may ask you to create new login details.

Old customer-number login Your old customer number is a 10-digit number and is different from a savings account number.
New username Existing online customers can be prompted to create a username and password for future access.
Verification The setup process can use codes sent to your registered mobile number and email address.
Memorable questions These form part of future identity checks and account-recovery support.
Travelling abroad? Leeds Building Society advises customers to contact it before travelling if they expect to use online services, because website access may not be available from some countries.

Leeds Building Society Account Help for Existing Savers

Existing savings members can use online services, secure messaging, telephone support, branch service or post depending on the account. Some online accounts cannot be transferred or fully managed in branch, so the product type matters.

Check a balance Log in to your online account if the product supports online management.
Request a withdrawal Use the route allowed by your product. Online accounts can have different withdrawal arrangements from branch accounts.
Send a secure message After logging in, choose the account and enquiry type before sending your question.
Change contact details Savings customers can change certain mobile, email and address information through online services using security checks.
Move to another savings product You may need to open the new account first and then ask Leeds Building Society to transfer the balance.
Maturing account Read the maturity instructions carefully before allowing funds to roll into the default maturity account.

Change Your Address, Name, Phone Number or Direct Debit

The process depends on whether you have a savings account or mortgage. Savings customers can make some changes online, while mortgage customers may need to contact the Society directly.

Change
Typical route
Useful detail
Savings address
Online personal-details section where eligible.
A one-time passcode may be used to confirm the change.
Mortgage address
Call 03450 505 075 and use the mortgage option.
Do not assume changing a correspondence address changes all mortgage-related details automatically.
Name
Evidence such as a marriage certificate, deed poll or other accepted document may be required.
Check whether the Society needs a certified copy.
Direct Debit bank details
Contact Leeds Building Society.
The Society currently asks for 10 working days’ notice to change Direct Debit account details.
Direct Debit name/payment date
Contact Leeds Building Society.
The Society currently asks for at least 3 working days’ notice, subject to the payment cycle.

Leeds Building Society Mortgages

Mortgage users generally fall into four groups: first-time buyers, home movers, people remortgaging from another lender, and existing Leeds Building Society borrowers deciding what to do next.

First-time buyer Check deposit, affordability, product fee, monthly payment and home-buying costs before setting your budget.
Home mover Check whether your current mortgage can move with you and whether additional borrowing is needed.
Remortgage Compare the total cost after fees and any Early Repayment Charge from your existing lender.
Existing Leeds borrower Use the existing-customer route for deal switching, overpayments, statements and mortgage changes.
Mortgage warning: your property could be repossessed if you do not keep up repayments on your mortgage. A lower headline rate is not automatically a cheaper deal after product fees, Early Repayment Charges and other costs.

Existing Leeds Building Society Mortgage Customers

Existing borrowers can switch deals, make payments, overpay, consider additional borrowing, review statements and ask for help with payment difficulties.

Switch deal Online switching may be available when you are near the end of your current deal and do not need other mortgage changes.
Make a payment Use the mortgage payment guidance for normal payments, one-off payments and overpayments.
Borrow more Additional borrowing is subject to affordability and lending criteria.
Change term or repayment method This normally requires direct contact or an appointment rather than a simple online rate switch.
Current 2026 switching detail: Leeds Building Society states that existing-customer deals are the same as or better than equivalent new-customer deals. It is also currently advertising £200 cashback on qualifying existing-customer mortgage deals chosen on or after 2 June 2026. The cashback can be changed or withdrawn, so check the live terms before relying on it.

Mortgage Payment Difficulties: Contact Leeds Early

Leeds Building Society asks borrowers who are experiencing financial difficulty to get in touch as early as possible. Waiting until several payments have been missed can reduce the range of options available.

Review household income and essential spending.
Check when your current mortgage product ends.
Find your mortgage account number.
Prepare details of any missed or upcoming payments.
Explain any temporary or permanent change in income.
Contact the Society before cancelling a Direct Debit without a plan.

Leeds Building Society Branch Finder, Leeds Central Branch and Map

Leeds Building Society maintains a network of 51 UK branches. Standard published branch hours are generally Monday to Friday from 9:30am to 4:45pm, with limited Saturday opening at participating locations.

Leeds Central Branch

27-28 Commercial Street
Leeds
LS1 6EX

Phone: 0113 225 7555

Monday-Friday: 9:30am-4:45pm

Saturday: limited opening. The branch is normally listed as open 9:30am-12pm on the first Saturday of each month and on the first and last Saturday of the tax year.

Sunday and bank holidays: closed.

Head office is different from the customer branch. Leeds Building Society’s head office is at 26 Sovereign Street, Leeds, LS1 4BJ. If you need routine face-to-face member service, use the branch finder instead of assuming the head office operates as a walk-in branch.

Fraud, Suspicious Calls and Leeds Building Society Account Security

If someone is pressuring you to move money, share security details or install remote-access software, stop the conversation. Leeds Building Society says it will never ask you to disclose your full password.

Do

  • Use a unique, strong online password.
  • Check statements and recent activity regularly.
  • Keep your phone number, email and postal address up to date.
  • Contact Leeds Building Society quickly if activity looks unfamiliar.
  • Use a separately verified telephone number.

Do not

  • Share your full password.
  • Share a one-time passcode with a caller.
  • Transfer savings because an unknown caller tells you to.
  • Allow an unexpected caller remote access to your device.
  • Use banking links from suspicious emails or texts.
Suspected fraud: Leeds Building Society instructs members who believe they have been a victim of fraud or see suspicious activity to call 03450 505 075 immediately during the Society’s published telephone hours.

How Much Leeds Building Society Savings Are FSCS Protected?

Leeds Building Society’s current savings information states that eligible deposits are protected by the Financial Services Compensation Scheme up to a total of £120,000 per eligible depositor with Leeds Building Society.

£120,000 Current standard FSCS protection limit for eligible deposits per eligible depositor with Leeds Building Society.
Per depositor The limit applies to the eligible person’s combined Leeds Building Society deposits, not separately to every savings account.
Joint accounts Eligible joint-account holders can each have their own protection entitlement under FSCS rules.
Do not multiply protection by account count. If one eligible person holds several Leeds Building Society savings accounts, the standard limit is applied to the eligible combined deposits, not separately to each account.

Power of Attorney, Joint Accounts and Someone Else’s Account

Account access becomes more complicated when another person needs authority to help. Leeds Building Society has separate procedures for Power of Attorney, bereavement and adding another savings account holder.

Power of Attorney The Society may require its attorney/deputy form plus the registered authority and identity evidence.
Online account restriction When an attorney is added to an online savings account, Leeds Building Society says the account can still be viewed online but cannot be managed online in the usual way.
Joint savings account Check the product terms first because not every savings account necessarily allows a second account holder.
Bereavement A Power of Attorney ends on the account holder’s death, so bereavement follows a different legal process.

Accessibility and Extra Support

Leeds Building Society provides accessibility support for members who need help communicating, reading documents or visiting a branch. Its branch guidance states that branches have induction hearing loops, and branch accessibility details are available through AccessAble.

Hearing support Branches provide induction loops for people using compatible hearing aids.
Physical accessibility Use the individual branch accessibility guide before travelling.
Writing and signing Some in-branch aids include signature guides, pen grippers, magnifying glasses and clipboards.
Tell the Society what you need Contact the support team or branch if a reasonable adjustment would make the service easier to use.

How to Make a Complaint to Leeds Building Society

A useful complaint should explain what happened, when it happened, what you have already done and what outcome you would like Leeds Building Society to consider.

Your contact details.
Savings or mortgage account reference.
Important dates and events.
Names or teams already contacted.
Relevant letters, messages or statements.
The practical or financial effect.
The resolution you are requesting.
A copy of everything you send.
Telephone 03450 505 075.
Written complaints Complaints Team, Leeds Building Society, 26 Sovereign Street, Leeds, West Yorkshire, LS1 4BJ.
Branch You can also discuss a complaint with staff at a local Leeds Building Society branch.
Financial Ombudsman If eligible and still unhappy after the Society’s final response, check the Financial Ombudsman Service referral rules and deadlines.
Six-month deadline: Leeds Building Society’s complaints information states that customers generally have six months from the date of the relevant final-response letter to refer an eligible complaint to the Financial Ombudsman Service.

Common Leeds Building Society Mistakes to Avoid

Using an old savings rate Savings issues and rates change. Use the current comparison page rather than an old search result.
Using an account number as a customer number The old online customer number is a separate 10-digit identifier, not the same as your savings account number.
Moving an ISA as ordinary cash Use the formal ISA transfer route when preserving ISA status matters.
Visiting the head office for branch service Use the branch finder for customer-facing branch services.
Waiting too long to switch mortgage deals Check your deal end date early enough to understand product-switch options before the current rate ends.
Ignoring mortgage support until arrears build Contact the Society early if payments are becoming difficult.
Assuming all accounts work in branch Some online savings tasks must be completed online or through secure messaging.
Sharing a verification code A legitimate security code should not be read to an unexpected caller who asks for it.

Before Opening a Leeds Building Society Savings Account

Check the exact product issue number.
Compare AER, not only the product name.
Check the minimum opening balance.
Read withdrawal restrictions.
Check whether opening is online, branch or post.
Read maturity arrangements for fixed products.
Check ISA status where relevant.
Confirm FSCS protection for your total eligible balance.
Read the Summary Box.
Save the terms applying when you open the account.
