Emergency fund or paying off debt first

Sorting out money usually comes down to one question: do you build savings first, or clear what you owe? The order that most free debt advice follows is a small cash buffer first, then priority debts, then everything else. Priority debts are the ones with serious consequences if they are missed, and mortgages sit at the top of that list: they are priority debts, and a lender could repossess and sell the home to recover the money¹.

The reason a buffer comes first is practical. Without cash, an unexpected bill goes on a card or an overdraft, and the debt you were trying to clear grows again. Government-backed guidance from MoneyHelper puts the emergency fund target at three to six months of essential outgoings². That is a target, not a starting point, and it is not realistic for everyone while debts are being paid.

What sits between the two is interest. Money put towards a debt with a high rate saves more than the same money earns in a savings account, which is why clearing expensive debt usually beats saving beyond a small buffer. The exception is a debt with an early repayment charge, where paying early can cost more than it saves.

Emergency fund first, then debt: the usual order

The order that free debt services set out is not arbitrary. It starts with the debts that can take your home, your energy supply or your liberty, and only then moves to the debts that damage your credit file but stop short of that.

Priority debts come first. Mortgages are priority debts, and the lender's remedy is repossession and sale¹. Gas and electricity arrears are treated as a priority debt because the supply can be disconnected². Government debts, including tax credits and benefit overpayments, are usually priority debts too, and enforcement can include bailiffs visiting, deductions from earnings, and prison in rare cases⁶. In Scotland, council tax arrears can lead to a sheriff officer being asked to take money from earnings or a bank account⁷.

A debt management plan follows the same logic. Payments into a plan are made after household bills and living costs, and priority debts are always paid first⁸. A budget built for a debt adviser starts with priority debts, because those are the ones that need dealing with first³. If there is no money available to pay priority debts at all, the guidance is to make contact for advice rather than to start paying a plan³.

Where a lump sum arrives, the same rule applies: it will usually need to be used to clear priority debt first⁹. That is the point at which the emergency fund question becomes concrete. A buffer of a few hundred pounds protects the plan; a large savings pot while a mortgage is in arrears does not.

Why interest on debt changes the sums

Interest is the reason the order is not simply "save everything first". Money paid against a debt stops interest being charged on that amount, and money held in savings earns interest instead. Where the debt rate is higher than the savings rate, clearing the debt wins on the arithmetic.

The effect compounds over time. Extending a mortgage term lowers the monthly payment but means paying more interest overall¹⁰. Switching to an interest-only mortgage is not a long-term solution: only the interest is paid, and the capital has to be repaid before the end of the term¹¹. Both options free up cash now at a cost later, which is the same trade-off as saving instead of overpaying.

Some debts carry interest that restarts or accrues in ways borrowers do not expect. On a Help to Build equity loan, missed payments can mean recovery costs or interest on the amount owed, and from year 7 onwards the interest rate rises in line with the consumer price index plus 2%¹². On a Help to Buy equity loan, a part repayment changes how interest is worked out, using the percentage of the loan left to repay and the original market value of the home¹³. Self-employed taxpayers who reduce their payments on account and then owe more can be charged interest by HMRC on the difference¹⁴.

Where a debt has already gone to court, interest can be added to a debt over £5,000. This is called statutory interest and is currently 8%¹⁵. That is a rate no ordinary savings account matches, which is why court judgments sit firmly in the "clear first" column.

When early repayment fees make paying off debt a loss

Paying a debt early is not always cheaper. An early repayment charge is a charge levied by the mortgage lender when the loan is repaid in full or in part before a date or event specified in the contract⁴. It applies if you remortgage during the initial fixed or tracker period of your mortgage¹⁵.

The charge is common enough that it should be checked before any lump sum is paid. There is often an early redemption fee if you remortgage early¹⁶. Fixed rate mortgages often include a financial penalty if the mortgage is repaid early over the fixed rate period, and this is called an early repayment charge¹⁵.

The same principle appears outside mortgages. The Green Deal loan can be paid off early, but there may be extra costs for doing so¹⁷. Anyone weighing a lump sum against a loan balance needs the charge figure and the remaining interest figure side by side, because the charge is deducted from the benefit of clearing early.

Saving or investing versus clearing debt

Investment industry guidance is blunt on this point: investment is not suitable as a way to get out of debt¹³. The same warning appears across the industry's own new-to-investing material¹⁴. That rules out investing as a route out of problem debt, though it does not rule out investing once debts are cleared.

The same guidance sets a condition before investing at all: keep an appropriate amount of cash in a bank or building society so it can be accessed quickly for unexpected outgoings or emergencies¹⁴. That is the emergency fund, and it comes before investing rather than after.

For anyone carrying multiple debts, the alternatives to a consolidation loan are a debt management plan, a debt relief order, an individual voluntary arrangement, and the Debt Arrangement Scheme in Scotland⁵. A debt management plan is usually for people who have some money left at the end of the month after priority bills, but not enough to pay all their debts¹⁹. It suits people who find it hard to pay the amount they originally agreed but still have money left after essential living costs²⁰. In Scotland, it will usually be better to use the Debt Arrangement Scheme instead of a debt management plan²¹.

Debts in your name, not your address

Debts belong to a person, not the address. You do not have to pay money owed by someone who used to live in your home²³. That holds even where the post keeps arriving, and the practical response is to write "not at this address" on the envelope and return it to sender, with no postage to pay²³.

The rule that does catch people out is joint borrowing. You can be chased for money if your name is on the contract, and that is true even if your relationship with the other person has changed²³. Where an ex-partner applies for a debt in your name without telling you, that should be reported to the police²⁴.

Post in your name for debts that are not yours is a recognised sign of identity theft, alongside letters from solicitors or debt collectors about debts you do not recognise²⁵. There is a sample letter for complaining to a debt collection agency where you do not owe the debt²⁶.

Debts also end in defined ways. Unsecured debts in your name alone are settled from your estate, and if there are no assets at the time of death, debts in your name are written off¹⁰. Where an estate cannot cover everything, unpaid debts are paid in a set order before anything goes to people named in the will, or until the money runs out²⁷. The order runs from secured creditors, through funeral and administration expenses and preferential debts such as employee wages, to unsecured creditors, interest on unsecured loans, and finally deferred debts such as informal family loans²⁸. Any remaining debts are likely to be written off²⁸.

Free debt help: MoneyHelper and StepChange

Free help exists and it does not cost anything to use. StepChange Debt Charity gives free and impartial debt advice²², and its debt management plans are free because it is a charity²⁹. It can set up a plan, handle payments and negotiate with the people you owe money to³⁰. Its advice is based on a full assessment of your situation and support continues for as long as it is needed³¹. Free debt help is available online 24/7, and the service can be started, paused and picked back up³².

Advice NI points people to free and independent advice on debt management plans, or any kind of debt problem, from organisations like itself³⁴. Shelter Scotland lists free advice services that can help³⁵, and free advice is available from an approved money adviser at a registered charity³⁵. The Financial Ombudsman Service handles complaints involving cost of living, including debt³¹. The Financial Services Compensation Scheme points people in difficulty to free debt advice from StepChange, Which? and Citizens Advice³⁶.

Where a debt management plan provider has closed, Citizens Advice sets out what happens next for people whose plan was with that firm⁷. Remortgaging to deal with debts carries its own warning: expert debt advice should always come before remortgaging to deal with debts¹⁶.
