Bath Building Society Lifetime ISA

A Lifetime ISA is a savings account that pays a government bonus on top of what you put in, and Bath Building Society offers one as a cash account. You can open it if you are aged 18 to 39, pay in up to £4,000 a year, and the government adds 25% up to £1,000 each year until you reach your 50th birthday¹.

The money is meant for two things: buying a first home, or later life. Use it for either of those and the bonus stays yours. Take it out for anything else and you normally lose the bonus on that money and pay a charge. Bath Building Society's Lifetime ISA is a cash account, so it does not hold investments, and the Society's own site carries today's interest rate and the current terms¹.

This page covers who the account suits, how the bonus and withdrawal rules work, how to apply or move an existing Lifetime ISA across, and what protects your money. It does not quote a rate, because the provider's site has today's figures.

What it is and who it is for

The Lifetime ISA is a government savings scheme, and Bath Building Society notes it may change in the future¹. The Society's version is a cash Lifetime ISA, which means your money sits in a savings account rather than being invested in funds or shares. That matters for how it behaves: the value does not rise and fall with markets, but it also does not grow beyond the interest the account pays.

It is built for two groups of people. The first is someone saving towards a first home who wants the government top-up on their deposit. The second is someone saving for later life who wants the bonus alongside a pension. The scheme itself was designed for people aged 18 to 40 when it launched in April 2017, and the age rules have stayed in that shape since⁵.

Bath Building Society states plainly who the account is not for: savers who want a flexible ISA, a stocks and shares ISA or an innovative finance ISA⁶. If you want to invest rather than save in cash, or you want the freedom to take money out and put it back without losing your allowance, this is not the account for that. If you already own a home, the first home route is closed to you, though the account can still be held for later life.

The Society's wider ISA range includes fixed rate ISAs with terms of one, two or five years, and an instant access ISA⁷. The Lifetime ISA sits alongside those rather than replacing them, and you can hold more than one type of ISA across different providers in the same tax year, subject to the overall ISA allowance.

How it works

You pay money in, and the government adds 25% on top, up to £1,000 each year, until you reach your 50th birthday¹. Both the government bonus and any interest added to the account are tax free, though the Society notes tax rules may change¹. Interest is calculated daily and paid annually on 31 December, then added to the account¹.

The account is single. You cannot hold it jointly, and you can only hold one Lifetime ISA with Bath Building Society¹. You can also only subscribe to one cash ISA with the Society each tax year, so you would not be able to pay into both a Lifetime ISA and a Fixed Rate ISA with Bath in the same year⁸.

Withdrawals are where the rules bite. You can use the account to buy a first home 12 months after your first payment into it, without paying a charge¹. Withdraw for any other reason before you turn 60, and the usual Lifetime ISA rules apply: you lose the government bonus on the money you take out and pay a charge. Bath Building Society's Lifetime ISA is not a flexible ISA, so taking money out does not restore your subscription limit for that tax year¹.

If you withdraw the full balance, you must leave £1 in the account to keep it open, and the same applies after age 40¹. The account allows Additional Permitted Subscriptions, which means the spouse or civil partner of a deceased ISA customer can apply to use their allowance¹.

How the fees and charges work

There is no separate account fee for holding a Lifetime ISA with Bath Building Society. The costs that matter are the ones attached to the rules rather than to the account itself.

The first is the early withdrawal charge. Take money out for anything other than a first home, from age 60, or if you are terminally ill, and you normally lose the government bonus on that money and pay a charge on top. The Society's own site sets out the current terms and figures for its Lifetime ISA, and those are the numbers to check before you withdraw¹.

The second is the loss of the bonus itself. That is the real cost of treating a Lifetime ISA as an ordinary savings account.

The third is the effect on your allowance. Because this is not a flexible ISA, money you take out does not go back into your subscription limit for the year¹. Withdraw £2,000 in a tax year and you cannot replace it without using up allowance you have already spent.

There is also a practical charge to know about if you ever need money moved quickly. That is a general Society charge rather than a Lifetime ISA one, but it applies if you ask for that kind of transfer.

Who can apply and how to apply

You can open a Lifetime ISA if you are aged 18 to 39¹. You must apply at least 14 days before your 40th birthday, so the account is open and funded before the age limit closes¹. You need to be a UK resident for tax purposes, or a Crown Employee serving overseas, or the spouse or civil partner of a Crown Employee¹.

The account is single, so no joint applications¹. You can only hold one Lifetime ISA with Bath Building Society, and you can only subscribe to one Lifetime ISA in a tax year across all providers¹. If you are aged 40 or over and transferring a Lifetime ISA, you must use the application form plus a Lifetime ISA Transfer Form¹.

You can open the account on the Society's website, using its Mobile App, or by visiting one of its branches in Bath¹. The Society also accepts applications online or by contacting it directly if you would like support¹⁰.

Identity checks are part of opening any account. Bath Building Society's preferred way to identify you is through a Financial Crime Prevention Agency, and if that fails, or if you are under 18, it asks for further identification¹¹. If you opened an account with the Society less than a year ago, it will not need to perform a new identity check; if it was longer than a year, it will¹¹. Certified copies of documents must be certified within the last 12 months using the words "I confirm that I have seen the original document"¹¹.

Moving an existing Lifetime ISA across

Bath Building Society accepts full transfers of an existing Lifetime ISA into this account, but it does not accept transfers of any other type of ISA into its Lifetime ISA, and it does not accept partial transfers¹. The transfer form must include a handwritten signature¹.

Transfers out are also allowed. You can move current year and existing subscriptions to another ISA provider, and any subscriptions made in the current tax year must be transferred in full¹. That rule is standard across ISAs: you cannot split current year money between providers.

The Society accepts transfers in for all its ISA products that are available to open¹². For its other ISAs, the mechanics differ: you can transfer into a current Junior Cash ISA, Lifetime ISA or Instant ISA, but not into a Fixed Rate ISA, which requires opening a new account⁴. It only accepts partial transfers from deposits made in previous tax years, and any amounts paid in the current tax year must be transferred in full⁴. It also only accepts full transfers of Junior Cash ISAs and Lifetime ISAs⁴.

To transfer in, you complete and sign an ISA Transfer In form, available on the relevant product page, and open the account before submitting the form⁴. For transfers from cash ISAs, the transfer should be completed within 15 working days; for transfers from stocks and shares ISAs and Lifetime ISAs, it could take up to 30 calendar days⁷.

If you are moving a Lifetime ISA specifically, the transfer rules for Lifetime ISAs cover what has to move and what can stay behind, and the general process is set out in how to transfer an ISA.

How your money is protected

The Lifetime ISA is protected by the Financial Services Compensation Scheme, the UK's deposit guarantee scheme¹. Anything above the limit is not covered³.

That total matters if you hold more than one Bath Building Society account. If you hold accounts with other banks or building societies, those have their own separate limits.

The FSCS protects you if the firm fails, not if your circumstances change. It does not cover you for the Lifetime ISA withdrawal charge, for a fall in value (though a cash Lifetime ISA does not fall in value), or for money you withdraw and spend. It also does not cover you if you are a victim of fraud, which is why the Society publishes security and fraud guidance¹³.

If you are saving towards a first home, the Lifetime ISA explained page covers how the bonus and the property rules fit together, and how your ISA is protected sets out the protection rules across ISA types.

Problems, complaints and getting help

If something goes wrong, contact Bath Building Society first. The Society has an internal complaints procedure which details how it deals with complaints, and if it cannot resolve your complaint you can refer it to the Financial Ombudsman Service¹⁴. The Ombudsman is free and independent, and it publishes quarterly complaints data. In the quarter covering October to December 2025, it recorded 410 new complaints about cash ISAs, including cash Lifetime ISAs and Help to Buy ISAs, and 23 new complaints about investment-only Lifetime ISAs in the previous quarter¹⁵.

If you are struggling with debt, the Society points people towards Citizens Advice, MoneyHelper and StepChange Debt Charity¹⁷. If a Bath Building Society saver dies, the Society's customer service team offers support and practical guidance to help with the account¹⁸.

There are also practical steps worth knowing. Keep information about your account safe, and be alert to fraud: the Society publishes security and fraud guidance on its site¹³. If you are moving a Lifetime ISA to another provider, the transfer rules mean current year subscriptions must move in full, so plan the timing around the tax year.
