Owing money can feel like carrying several plates at once, and it's tempting to just pay whoever shouts loudest. But not all debts are created equal, and the order in which you tackle them can make a real difference to your stress levels, your credit file, and even whether you keep a roof over your head.
This guide is here to help you think through debt prioritisation in a clear, practical way. It's general information, not personalised financial advice, so if your situation feels complicated or overwhelming, please do reach out to a free service like [MoneyHelper](https://www.moneyhelper.org.uk) or [Citizens Advice](https://www.citizensadvice.org.uk). There's no shame in asking for help, and these services exist precisely for this reason.
Why "Prioritise" Doesn't Mean "Pay Off Fastest"
A lot of debt advice online focuses purely on interest rates: pay off whatever costs you the most first. That's a sensible principle in many cases, but it's not the whole picture in the UK. Some debts carry consequences far more serious than a bit of extra interest, things like losing your home, having your electricity cut off, or facing enforcement action.
This is why UK debt charities draw a clear line between priority debts and non-priority debts. Understanding this distinction is the first, and arguably most important, step before you even start thinking about interest rates.
Priority Debts: Deal With These First
Priority debts are the ones that carry the most serious consequences if left unpaid. They're not necessarily the ones with the highest interest rate, but the ones where non-payment could lead to losing something essential, like your home, or facing legal action.
These typically include:
- Mortgage or rent arrears: Falling behind here can eventually put your home at risk.
- Council tax arrears: Councils can move to enforcement relatively quickly compared to other creditors.
- Energy bills (gas and electricity): Suppliers have powers that other creditors don't, including, in some circumstances, disconnection.
- HMRC debts (such as unpaid tax or overpaid tax credits): HMRC has strong powers to recover what's owed.
- Court fines: These can lead to bailiff action or even, in rare and serious cases, imprisonment.
- Child maintenance arrears
If you're juggling several debts and money is tight, it's worth checking whether any of yours fall into this category. Missing a credit card payment is stressful, but missing a mortgage payment or council tax bill can escalate much faster and with more serious consequences.
A Quick Gut-Check
Ask yourself: "What's the worst that happens if I don't pay this one this month?" If the honest answer involves losing your home, being disconnected, or facing court action, it's almost certainly a priority debt.
Non-Priority Debts: Still Important, Just Less Urgent
Once your priority debts are covered (or at least you have a realistic plan for them), you can turn your attention to non-priority debts. These include:
- Credit cards
- Store cards and catalogues
- Personal loans
- Overdrafts
- Buy now, pay later arrangements
- Debts owed to friends or family
Don't mistake "non-priority" for "unimportant." These debts can still seriously affect your credit file, and interest can pile up quickly, especially on credit cards and overdrafts. They just don't carry the same immediate, severe consequences as the priority debts listed above.
Two Popular Approaches: Snowball vs Avalanche
Once your priority debts are under control, how do you decide which non-priority debt to pay down first? Two common approaches are worth understanding, though which suits you depends on your personality and circumstances as much as the maths.
The Avalanche Method
With this approach, you list your debts by interest rate, highest to lowest, and put any spare money towards the one with the highest rate first, while making minimum payments on the rest. Mathematically, this tends to save you the most money over time, since you're tackling the most expensive debt first.
The Snowball Method
Here, you order debts by size, smallest to largest, regardless of interest rate. You clear the smallest debt first, then roll that payment into the next smallest, and so on. It can cost slightly more in interest overall, but many people find the quick wins genuinely motivating, and that sense of progress can matter just as much as the numbers.
Neither method is "correct." Some people need the psychological boost of clearing a debt entirely to stay motivated. Others are more comfortable following the strictly cheapest route. Be honest with yourself about which approach you're more likely to stick with, because a plan you abandon after two months won't help you much.
Building Your Own Prioritisation Plan
Here's a simple way to approach this for your own situation:
- List everything you owe, including who it's owed to, the balance, the interest rate, and the minimum monthly payment.
- Mark which are priority debts. Be honest, and if you're unsure whether something counts, a free debt charity can help you check.
- Make sure priority debts are covered first, even if that means only paying minimums elsewhere for now.
- Choose snowball or avalanche for your remaining non-priority debts, based on what will keep you motivated.
- Review regularly. Life changes, and so might your priorities, especially if your income or circumstances shift.
If you haven't already built a monthly budget that lays out your income and outgoings clearly, it's worth doing this alongside your debt plan. It's much easier to prioritise debts when you can see, in black and white, what's coming in and what's already spoken for. Genwel's budgeting tools can help you get that full picture before you decide where extra payments should go.
What About Savings While You're Paying Off Debt?
This is a question we hear a lot, and it's genuinely tricky. Broadly speaking, it's usually worth having a small emergency buffer, even a modest one, so an unexpected bill doesn't push you into new debt. Beyond that, whether to prioritise saving or debt repayment often comes down to comparing the interest you're paying versus what you'd earn saving, and your own peace of mind matters too.
If you're wondering how ISAs or other savings vehicles fit into this picture, it's genuinely worth checking current allowances and rules, as these change over time, and considering whether saving alongside debt repayment makes sense for your circumstances. A regulated financial adviser or MoneyHelper can talk this through with you in more detail than general guidance can.
Signs You Might Need Extra Support
Sometimes, despite your best efforts, the numbers just don't add up, and that's when it's time to get proper support rather than trying to manage alone. Consider reaching out if:
- You're only able to make minimum payments, or less, across multiple debts
- You're using credit to pay for essentials like food or energy
- You're receiving letters about missed payments or arrears
- You feel anxious every time the post arrives or the phone rings
- You genuinely don't know where to start
Free, confidential debt advice is available from organisations like StepChange, National Debtline, and Citizens Advice. They can help you look at formal options too, such as debt management plans or, in some circumstances, more formal solutions like Debt Relief Orders or Individual Voluntary Arrangements. These carry serious implications, so they're always best discussed with a qualified adviser rather than decided on alone.
Bringing It All Together
Prioritising debt isn't about finding one clever trick that solves everything. It's about understanding which debts carry the most serious consequences, being realistic about your income and outgoings, and choosing a repayment approach you can actually stick to.
Start by separating priority from non-priority debts, since that distinction protects the essentials, like your home and utilities, before anything else. From there, whether you choose the avalanche method, the snowball method, or a mix of both, the most important thing is having a clear plan and reviewing it as your circumstances change.
And if things ever feel unmanageable, remember that free, judgement-free help is only a phone call or a click away. Getting support early nearly always leads to better outcomes than waiting until things feel like a crisis.
