Who is Leeds Building Society?
Leeds Building Society is one of the UK’s largest building societies, offering savings, mortgages and ISA products focused on straightforward, member-focused service. Its ISA range includes online-only and branch-managed Cash ISAs, and eligible deposits are protected by the UK Financial Services Compensation Scheme (FSCS) up to applicable limits.
Pros and cons
- Pros
- Competitive variable interest rate (around 4.02% AER tax-free) for balances of £1,000 or more, helping maximise tax-free returns
- Easy access with unlimited online withdrawals—you can take money out when you need it without notice or penalty
- Can be managed and opened online, with unlimited deposits and the option to transfer in previous years’ ISA funds
- Cons
- Interest is variable and can go down as well as up
- Minimum opening balance of £1,000 is higher than some competitors
- Not a flexible ISA—any funds you withdraw cannot be replaced later in the same tax year without using part of your annual ISA allowance
What is a Cash ISA?
A Cash ISA is a savings account where all interest you earn is completely tax-free. Every UK resident aged 18 or over gets an annual ISA allowance at the start of each tax year. For the 2025/26 tax year (ending 5 April 2026), the allowance is £20,000, and from April 2027 it will reduce to £12,000. Cash ISAs come in different types, including easy-access accounts and fixed-term accounts.
What is an easy-access Cash ISA?
An easy-access Cash ISA allows you to withdraw your money whenever you need it, without paying any penalties. The interest rate is variable, so it can rise or fall over time. Some easy-access ISAs are also flexible, meaning withdrawn money can be replaced without affecting your allowance.
Who is Leeds Building Society Online Access Cash ISA good for?
The Leeds Building Society Online Access Cash ISA is a good option for savers who want a competitive tax-free rate with easy online access to their money and are comfortable managing their account digitally. It suits people saving for short-to-medium-term goals or building an emergency fund and who can meet the £1,000 minimum to open. However, it may be less appealing to those seeking flexible ISA features (where withdrawals can be replaced without affecting the allowance) or who prefer branch-based support for all transactions.

Outstanding Service and Truly Exceptional Staff
Leeds Building Society has been an absolute pleasure to deal with. Every interaction I have had with them has been marked by staff who are extremely polite, professional, helpful, and patient. It makes such a difference when a financial institution treats you with genuine respect and care. What really stands out is how proactive they are. Whenever savings rates change, they reach out with alternative options so you are always getting the best value, something very few providers bother to do. They also handle the majority of requests quickly and efficiently over the phone, which makes managing your accounts incredibly convenient. Their Service is consistently smooth, reassuring, and customer‑focused from start to finish. I would 100% recommend them.
4.0 ★★★★
4 stars to the bank instead of 5 only because the online banking facility is rather restrictive, no repository of digitised bank statements for example. The T&Cs of my savings account were not easy to find online either, I had to request these by email as I misplaced them at time of opening the account. Overall, a robust Building Society, wishing them continuity and all the best.
