There are around 350 credit unions operating in the UK today, holding £4.91bn in total assets and serving 2.16 million adult members, according to the Bank of England's Credit Union Quarterly Statistics for 2025 Q3. In November 2025, HM Treasury committed £30m to a Credit Union Transformation Fund through Fair4All Finance as part of its Financial Inclusion Strategy. In March 2026, the Government announced reforms to the common bond rules that determine who can join. And in their joint Mutuals Landscape Report published in December 2025, the Prudential Regulation Authority (PRA) and Financial Conduct Authority (FCA) confirmed they would review the credit union regulatory framework in 2026/27.
What is a credit union??
In the FCA's own words, a credit union is a financial co-operative owned and controlled by its members. Members pool their savings, and the union lends them to other members at rates capped by law. Surpluses, where they exist, are returned to members as dividends rather than paid out to external shareholders. There is no parent company, no listed stock, no quarterly earnings call.
Membership has historically been governed by a common bond, usually based on where you live, where you work, or what you do for a living. The reforms announced by the Economic Secretary to the Treasury in March 2026 will allow credit unions to admit students to locality-based unions, retain employer-bond members after retirement, and accept relatives of existing members regardless of household.
How a credit union actually works
The mechanics are deliberately simple. When you join, you open a share account and start saving, often by standing order, Direct Debit or payroll deduction. Those deposits, alongside everyone else's, form a single pool of capital. The credit union lends that pool back out to other members in the form of personal loans, with interest paid by borrowers covering the cost of running the union and, in good years, generating a modest surplus.
That surplus has only three places to go. It is held back to strengthen reserves, reinvested into services, or distributed to members as a dividend. There are no outside shareholders, which is the structural reason credit union loan rates can sit so far below those of commercial lenders. Governance follows the same logic: each member has one vote at the AGM, regardless of whether they have £5 or £15,000 on deposit, and the board is elected by and from the membership.
Are there benefits of being in a credit union?
For savers, deposits with a UK credit union are protected by the Financial Services Compensation Scheme up to £120,000 per person, per authorised firm, following the increase that took effect on 1 December 2025. That is identical to the protection offered by Lloyds, Barclays or HSBC.
For borrowers, interest on loans is capped by statute at 3% per month in Great Britain, equivalent to a maximum 42.6% APR, and at 1% per month in Northern Ireland. In practice, most credit union loans sit well below the cap, with rates starting from around 2.9% APR for prime borrowers and typically clustering around 12.7% APR for standard personal loans. That sits comfortably below most bank overdrafts and is a fraction of what payday lenders charge. Many credit unions also offer payroll deduction, junior savers' accounts, cash ISAs, and, at a handful of larger unions, current accounts and even mortgages.
How the rates stack up against the high street
On mainstream personal loans of £7,500 and above, large established credit unions are competitive with the major banks rather than cheaper overall. HSBC publishes a representative APR of 6.2% on personal loans of £7,500 to £20,000, with a maximum offered APR of 22.9%. Glasgow Credit Union, one of the largest in the UK, advertises personal and car loans of £500 to £25,000 from 6.9% APR. London Mutual Credit Union shows a representative example of £10,500 over 37 months at 9.38% APR. Smaller community unions sit higher: London Community Credit Union, for example, prices personal loans between 14.9% and 42.6% APR, depending on the amount. For context, the Bank of England's effective interest rate on new personal loans across all UK banks and building societies was 9.06% in February 2026 (Money and Credit, February 2026), the actual rate paid by borrowers rather than a marketing headline.
On the products where banks are most expensive, the credit union case is far more clear-cut. As of February 2026, the effective rate on interest-charging arranged overdrafts at UK banks was 22.00%, and the effective rate on interest-charging credit cards was 21.65%. HSBC's own arranged overdraft is priced at 39.9%. Even mid-range credit union loans, priced at 14.9% to 19.6% APR, sit materially below those levels, and a typical Glasgow Credit Union or London Mutual rate undercuts them by a wide margin.
Are there any arguments in favour of credit unions over banks?
The case rests on four points.
First, alignment of interest. A bank exists to generate returns for shareholders. A credit union exists to serve its members, who are also its owners. There is no quarterly earnings pressure to push members into expensive overdrafts or premium accounts.
Second, underwriting that considers affordability, not just an algorithmic credit score. Credit unions are smaller and locally rooted, and they will take a view on personal circumstances. That is why people on modest incomes or with thin credit files can borrow at sub-cap rates rather than being pushed to specialist lenders.
Third, a built-in savings discipline. Many credit unions operate "save-as-you-borrow" plans, in which part of every loan repayment is diverted to the borrower's savings account. By the time the loan is repaid, the borrower has built a financial buffer, an outcome that does not arise from a bank loan or an overdraft.
Fourth, regulatory parity on safety. Credit unions are dual-regulated by the PRA and the FCA, and deposits are protected by the FSCS up to £120,000 per person, per institution, following the increase that took effect on 1 December 2025. That is identical to the cover at any major bank.
The trade-offs are real. Most credit unions cannot match the technology stack, branch network, product breadth or instant-decision speed of a Lloyds or a Monzo. Loan ceilings are typically lower, and only a handful of unions offer current accounts or mortgages. For a salaried prime borrower wanting a £25,000 loan with same-day funding, a credit union may not be the right call.
But for almost everyone else, particularly those borrowing under £5,000, those repeatedly slipping into overdraft, and those who would otherwise reach for BNPL or a doorstep lender, the cost saving is immediate and material.
How to join
Joining is straightforward. The Find Your Credit Union directory at findyourcreditunion.co.uk lets you search by postcode, employer or trade. Most unions accept online applications, with opening deposits of £1 to £5. You will need a standard ID and proof of address. Once a member, you can save by standing order, Direct Debit or payroll deduction, apply for a loan, and receive a dividend if the union declares one.
Credit unions will not displace the high street banks, and they do not aim to. But for savers seeking community-anchored institutions, and for borrowers locked out of mainstream credit, they remain Britain's most underused financial co-operative. With Whitehall now actively pushing to double the mutuals sector, the next few years may finally bring them in from the margins.
