Bath Building Society - formally Bath Investment & Building Society - is a mutual building society based in Bath, founded in 1904. There were once four building societies in Bath, but all the others merged away over the decades; Bath Building Society remains the last one standing as an independent mutual, owned by and run for the benefit of its members. Profits are reinvested in the society rather than paid to external shareholders. It is a small operation by any measure - around 14,000 members and two branches - but that size is arguably part of the appeal. They don't have huge call centres, which means you get straight through to the team when you call.
Bath Building Society's savings range on DepositScout currently centres on one product: a Lifetime ISA (LISA). The account pays a variable rate of 2.60% AER and can be opened with as little as £1. Access is restricted to age 60 or above, or to a qualifying first home purchase - standard LISA rules apply, and unauthorised withdrawals carry a government penalty.
One thing worth knowing if you are thinking about transferring an existing LISA here: Bath accepts transfers from other cash LISAs and Stocks & Shares LISAs, but not from a standard cash ISA or a Help to Buy ISA. That is a broader transfer policy than many of the higher-rate app providers offer, so it can be a practical choice if you are moving a Stocks & Shares LISA and want a straightforward cash home.
Deposits are protected up to £120,000 per person by the FSCS - note that this is a higher limit than the standard £85,000 that applies to bank accounts, reflecting the building society structure.
Bath Building Society suits savers who value stability and straightforward service over chasing the very top rate. The 2.60% LISA rate sits in the middle of the cash LISA market - not the highest you will find, but with no introductory bonus to erode after twelve months and a more flexible transfer-in policy than most of the higher-paying rivals.
There are no current account switch offers here, and the savings range available through DepositScout is narrow. If you need a broad range of easy access or fixed-term accounts, you may need to look elsewhere.
