Where Your Co-op’s Cash Sleeps: Ethical Banking Beyond the High Street

A co-op can have a beautiful constitution, a democratic board and a current account with a bank that lends to things its members would never vote for. That gap is not hypocrisy so much as inertia. Switching bank accounts is boring, paperwork-heavy and easy to postpone. But for community-minded businesses, where the cash sits is a governance decision, not just a finance one.
In 2026, the UK has a small but real ecosystem of ethical and mutual finance. It is not a single shelf of perfect options. It is a set of trade-offs between member ownership, transparency, lending practice, eligibility and practical banking. The trick is to choose deliberately, not just stick with the devil you know.
Write Down What ‘Ethical’ Means to Your Members
Before comparing banks, agree a treasury policy. Ask members what they want the co-op’s money to do. No lending to fossil fuel expansion? A preference for local or community lending? A living wage for staff? Published lending policies? A bank that is itself owned by its customers? You will not get every wish, but you need a scorecard.
This is where open books earn their keep. Publish a short policy: where cash is held, why, how much is kept in each institution, and how often the board reviews it. If the co-op holds significant reserves, set a threshold above which the board must report to members. Transparency is not just a value in the constitution; it is a habit.
The Menu: Credit Unions, CDFIs and Ethical Banks
Credit unions are member-owned financial co-operatives. They are regulated by the Prudential Regulation Authority and the Financial Conduct Authority, and eligible deposits are covered by the Financial Services Compensation Scheme up to £85,000 per person per institution. Many are small and local, with a common bond. They are excellent for savings and loans, but not all offer business current accounts. Check what is available before you set your heart on one.
CDFIs — community development finance institutions — lend to businesses and social enterprises that mainstream banks may overlook. They are not usually deposit-takers, so they are more relevant if you need a loan than if you need a current account. Responsible Finance is the trade body for many of them. Eligibility varies, and you will need to make a proper application, but CDFIs can be a values-aligned source of growth finance.
Ethical banks include names such as Triodos and Charity Bank, which publish information about their lending and focus on social or environmental purposes. The Co-operative Bank is another familiar name, but ownership and governance change over time; check the current structure rather than relying on the logo. Building societies are mutuals, which is a point in their favour, but mutual ownership alone does not guarantee an ethical lending policy. Read the published policies, not just the marketing.
The Switching Bit
Do not move everything in one heroic weekend. Run a parallel account for a month. Check that payroll, Direct Debits, standing orders, card payments, online banking, dual authorisation and signatories all work. If you use the Current Account Switch Service, confirm your chosen provider participates for business accounts; not every ethical provider does. Keep the old account open long enough for cheques and stragglers to clear.
Tell members what you are doing and why. Update invoicing, HMRC, payroll, insurers and regular suppliers. If your constitution requires member approval for a change of banker, get it. Spread deposits across institutions where needed, and remember the £85,000 FSCS limit is per institution, not per account. For larger reserves, consider a treasury policy that sets concentration limits.
Member Oversight Is the Real Ethical Product
A bank can call itself ethical, but your co-op still needs member oversight. Report at the AGM on where the cash is, what the bank lends to, and whether the board has reviewed the relationship. Publish the treasury policy alongside the accounts. If the bank is sold, changes ownership or shifts its lending, review the relationship again.
The best ethical finance decision is not a badge on a website. It is a member-approved policy, a clear switching plan and a board that can explain its choices without hiding behind jargon. Move deliberately, keep the receipts, and let members see the workings.
