Castlemilk Credit Union is a not for profit community lender for people who live or work in the G postcode area. It offers savings and loans to members, including junior accounts for under 18s. Here is who can join, how to bank with it, what happens if you fall behind with repayments, how to complain, and how your money is protected.

Castlemilk Credit Union name card

Castlemilk Credit Union is a not for profit community lender serving people who live or work in the G postcode area. It is a credit union, which means it is owned by its members and provides loans, savings, bank accounts and other services to them rather than to the public at large1. To join you must be 18 or over and either live or work in the G postcode area2.

It is authorised by the Financial Conduct Authority under firm reference number 213657, and its authorisation has been effective since 2 July 20023. It also appears on the Bank of England's Prudential Regulation Authority list of credit unions incorporated in the UK4. Savings held with it are covered by the Financial Services Compensation Scheme, the same protection that applies to money in a bank5.

This page covers what the credit union offers, who can join, how to bank with it, what happens if you fall behind with repayments, how to keep your details safe, how to complain, and how your savings are protected.

What Castlemilk Credit Union is and who it serves

Credit unions are not for profit community lenders providing affordable loans and savings5. They exist to help members in need of financial support, and they provide access to fair and affordable credit for people with a poor credit history, including those who cannot access mainstream forms of credit or who may not know about affordable providers5. The wider community lending sector, which includes credit unions and community development finance institutions, is a growing source of affordable credit but still has limited reach7.

Castlemilk Credit Union follows that model. It is a member-owned organisation, so the people who save and borrow are the people the organisation exists for. You must be a member to get a loan from a credit union, so joining comes first8. Membership is not the same as a customer relationship with a bank: members have a say in how the credit union is run, and any surplus is used for the benefit of members rather than paid to outside shareholders.

The credit union's common bond, the rule that defines who it serves, is the G postcode area2. That is a geographic common bond rather than one based on an employer or trade, which is the most common arrangement. Credit unions in Great Britain are regulated by the Financial Conduct Authority and the Bank of England's Prudential Regulation Authority9.

For a wider picture of how these organisations work and how they differ from banks, see Credit unions: a complete guide.

Who can join: living or working in the G postcode area

Credit unions ask for two recent documents to prove identity and address when you join.

To join Castlemilk Credit Union you must be 18 years or over and either live or work in the G postcode area2. You do not have to live in Castlemilk itself. The test is the postcode area, so someone who works in Glasgow but lives elsewhere in the G area, or the reverse, meets it.

Credit unions generally set a common bond, and the usual formulation is that a member must either be living or working within that area10. Some credit unions extend membership to family members: as long as one member of a family meets the common bond requirements and has joined, other family members living at the same address can usually join too11. If you are outside the G postcode area, another credit union may cover where you live or work, and the trade body's finder tool can help you locate one12.

When you apply, expect to prove who you are and where you live. Credit unions usually ask for two recent documents to prove identity and address, such as a passport, driving licence, student or work ID card, bus pass, birth certificate, bank statement or energy bill1. The simplest approach is to visit or call the credit union first to confirm exactly what it needs before you gather documents12.

Accounts for children and young people

Castlemilk Credit Union offers a juvenile account for members under 18. Its guidance states that under 18s can sign up for a juvenile account by themselves or with a parent or guardian2. That is a wider route than many credit unions offer: some require a legal parent or guardian to open the account13, and others restrict junior accounts to children under 1614.

The age at which a young person can act alone varies across financial products. From age 16 you can open a bank account without asking your parents15. A Junior ISA works differently: for children under 16 only a parent or legal guardian can open one, while children aged 16 or 17 can open their own16. So a teenager has several routes, and the right one depends on what the money is for and how long it will be left alone.

Junior savings accounts at credit unions are usually designed for regular small deposits, with withdrawals restricted to protect the savings. Some credit unions require written approval from the parent or guardian who opened the account before a withdrawal, and both signatures once the child is 7 or over14. Ask Castlemilk Credit Union what its own junior account allows before you open one.

For the wider picture on children's savings, including Junior ISAs, see Savings accounts: a complete guide and ISAs: a complete guide.

How to bank with Castlemilk Credit Union

Credit unions deliver their services in different ways. Some offer online and phone banking, some run a payroll partnership with your employer, and some operate a local branch or service point you can walk into17. Castlemilk Credit Union's own website is at www.castlemilkcu.co.uk, where its membership and service information sits3.

How you apply varies between credit unions. Some open accounts instantly if you call into the office with photo and address identification18. Others let you apply online19. Some loan applications are made by registering for online access, completing an online application, connecting Open Banking and providing supporting documents20. Payment methods also vary: some credit unions accept deposits and loan repayments in the office, by standing order, bank transfer or chip and pin21.

Because these arrangements differ from one credit union to the next, the practical step is to check Castlemilk Credit Union's own site or contact the office to confirm how it takes applications, how you pay in, and whether it offers online access. The general rule for any credit union is the same: visit or call to confirm what information you need to join12.

For the products themselves, see Savings accounts: a complete guide, Loans: a complete guide and Current accounts: a complete guide.

If you fall behind with repayments

If your circumstances change and you cannot keep up with repayments, contact the credit union as soon as possible so an alternative payment plan can be discussed19. That is the same advice that applies to any lender: if you think you might miss a payment, contact the lender quickly and talk through your options22.

There is a specific feature of credit union lending to understand. If you miss payments on a loan, the credit union may be able to use your savings to repay the loan23. Because members usually borrow against a record of saving, the savings and the loan are linked in a way they are not at a bank. That is worth knowing before you borrow, because it means money you have set aside may be applied to the debt.

Missing payments has consequences beyond the credit union. A default usually appears on your credit file after you have missed between three and six months' payments24, and extra charges are added if you miss payments on credit card debt25. If you do not meet the repayments on a loan, your account goes into arrears, which may affect your credit rating and limit your ability to access credit in future20.

If money is tight, free and impartial help is available. StepChange and National Debtline both offer debt advice at no cost, and the credit union itself should be your first call. For the full range of options, see Debt: a complete guide to help, solutions and your rights.

Keeping your security details safe

Checking statements and your credit report regularly is one of the simplest ways to spot fraud early.

Castlemilk Credit Union defines your security details as the unique information you provide online, over the phone or in person that identifies you and your accounts28. Its own guidance lists account number, National Insurance number and address as examples28. Other credit unions use the same definition and add a password, PIN number and security questions to the list29.

The rules the credit union sets out are straightforward:

  • Memorise your security details and securely destroy anything containing them as soon as you have received and remembered it28.
  • Never allow anyone else to use your security details28.
  • When you set or change them, make sure they cannot be easily guessed29.
  • Always be sure you know the person you are sending money to and that you are comfortable with the reason you are sending it28.

Good habits beyond the credit union help too. Check your bank and credit card statements regularly for suspicious activity and monitor your credit report30. Store documents carrying personal information, such as your driving licence, passport, bank statements and utility bills, in a safe and secure place31. If documents are lost or stolen, report them to the issuer, check your statements and credit report, watch out for phishing, use strong passwords and multifactor authentication, and consider applying for Cifas protective registration32.

What happens if fraud is suspected on your account

Tell the credit union straight away if you suspect or discover that someone else knows your security details, or if you believe your security details may have been misused28. Monitor your accounts and tell the credit union about any activity or transactions you do not recognise28.

If fraudulent activity is suspected, the credit union may suspend your account until it is satisfied your account is safe28. That is a standard response across credit unions, not a penalty: the account is frozen while the position is checked. If you think your card, online bank account or cheque book has been stolen or hacked, speak to your bank, building society or credit union straight away33.

There is help beyond the firm. Speak to your bank, building society or credit union, which can protect and reimburse victims of certain types of fraud, and report the matter to Action Fraud34. If fraud has been committed against you, for example if someone has used your identity, there may be a marker against your name to protect you, and you will be able to see this on your credit file35.

Making a complaint to Castlemilk Credit Union

You can make your complaint known to Castlemilk Credit Union in person at the branch, over the phone, by email or in writing6. The credit union acknowledges complaints within 3 working days from the date the complaint was received, and states that all complaints should be resolved within 8 weeks, with a copy of the resolution sent to you in writing6. It will provide you with a copy of its internal complaints procedure on request6.

That timescale matches the wider rule. Credit unions have eight weeks to investigate and give you their final response1. Across the sector, most routine complaints are resolved within two working days, and the credit union will attempt to resolve the matter within eight weeks of receipt36. Complaints can be made in person, by email or by letter, and verbal complaints are entered on a complaints form36.

Credit unions and other FCA authorised consumer credit firms must have a formal complaints procedure37. If you want to be sure your complaint is being handled correctly, ask the company for a copy of its complaints procedure38. If eight weeks pass without a final response, or you are unhappy with the outcome, you can take the complaint to the Financial Ombudsman Service1.

If you are in Northern Ireland, the Consumer Council runs a complaints handling service that requests copies of all communication between you and the company, contacts the company on your behalf, reviews the complaint and keeps you informed of the response39. You can submit a complaint to it online, by phone, letter or email40.

How your savings are protected

Loans and savings with credit unions are protected by the Financial Services Compensation Scheme5. All shares, which is what savings in a credit union are called, are eligible for protection under the scheme41. This is the same protection that covers money held with banks and building societies, and it means your savings are not lost if the credit union fails.

The scheme is the backstop, not the first line of defence. Credit unions are regulated by the Financial Conduct Authority and the Bank of England's Prudential Regulation Authority, which set the rules they must meet on capital, lending and how they are run9. Castlemilk Credit Union Limited is authorised by the FCA under firm reference number 213657, effective from 2 July 2002, and appears on the PRA's list of UK incorporated credit unions3. You can check a firm's status yourself on the FCA register.

One point to understand about credit union savings is that they are shares in the organisation rather than deposits in the ordinary sense, which is why the term shares is used. That does not change the protection: the scheme covers them41. Any dividend paid on savings is not guaranteed and is added after the annual general meeting, so savings should not be treated as a fixed return product42.

For how this compares with other places to hold money, see Savings accounts: a complete guide and Consumer protection in UK financial services: a complete guide.

Frequently asked questions

What is the website for Castlemilk Credit Union?

Castlemilk Credit Union's website is www.castlemilkcu.co.uk. It is listed as the credit union's website address on the Financial Conduct Authority register. The site carries its membership information, its complaints procedure and its fraud protection guidance. If you are looking for a different credit union, the trade body's finder tool at findyourcreditunion.co.uk can help you locate one, and MoneyHelper also carries general information about how credit unions work.

Do I have to live in Castlemilk to join?

No. The requirement is that you live or work in the G postcode area, not that you live in Castlemilk itself. You also need to be 18 or over to join in your own name. Credit unions set a common bond, which is the area or group they serve, and Castlemilk Credit Union's is the G postcode area. If you are outside it, another credit union may cover where you live or work.

Can a child open an account without a parent?

Castlemilk Credit Union states that under 18s can sign up for a juvenile account by themselves or with a parent or guardian. That is more permissive than many other credit unions, where a parent or guardian must open the account. From age 16 you can open a bank account without asking your parents, so a teenager has options either way. Ask the credit union what identification it needs for a junior account.

Which security details does the credit union use to identify me?

Castlemilk Credit Union describes your security details as the unique information you provide online, over the phone or in person that identifies you and your accounts. Its own guidance lists account number, National Insurance number and address as examples. Other credit unions include a password, PIN number and security questions in the same definition. Never allow anyone else to use your security details, and tell the credit union straight away if you think someone else knows them.

How long does the credit union have to resolve a complaint?

Castlemilk Credit Union says it acknowledges complaints within 3 working days of receiving them and that all complaints should be resolved within 8 weeks, with the resolution sent to you in writing. That matches the wider rule for credit unions, which have eight weeks to investigate and give a final response. If eight weeks pass without a resolution, you can take the complaint to the Financial Ombudsman Service.

Can I get a copy of the complaints procedure?

Yes. Castlemilk Credit Union states that it will provide you with a copy of its internal complaints procedure on request. Credit unions and other FCA authorised consumer credit firms must have a formal complaints procedure, so asking for a copy is a normal request rather than a special favour. You can also ask how your complaint will be handled and who will deal with it before you set out the details.

Is Castlemilk Credit Union regulated?

Yes. Castlemilk Credit Union Limited is authorised by the Financial Conduct Authority, with firm reference number 213657, and its authorisation has been effective since 2 July 2002. It also appears on the Bank of England's Prudential Regulation Authority list of UK incorporated credit unions. Credit unions in Great Britain are regulated by the FCA and the Prudential Regulation Authority. You can check the firm's entry on the FCA register yourself.
