Priority Debts vs Non-Priority Debts in the UK: What Comes First

This guide explains how UK debt classification systems work. It is not financial advice. If you are dealing with debt, a regulated debt adviser can help you understand your individual situation.

In the UK, debts are not all treated equally. The distinction between "priority" and "non-priority" debts is one of the most fundamental concepts in personal [debt management](/guide/debt-management-plans-what-creditors-can-and-cant-do), yet it is widely misunderstood. The classification has nothing to do with how much is owed or how aggressively a creditor chases payment. Instead, it is determined entirely by the consequences that follow if a debt goes unpaid.

This guide explains how the UK system classifies debts, what enforcement powers exist behind each type, the key legal thresholds and timelines that govern the process, and where the rules vary across England, Wales, Scotland, and Northern Ireland. Every claim in this guide is drawn from verified legislative, regulatory, or established advisory sources.

Priority debts are debts where non-payment can result in the most serious consequences — including the potential loss of a home, disconnection of essential services, or in limited circumstances, imprisonment. Non-priority debts are those where the creditor does not have these extra statutory enforcement powers and must generally obtain a court judgment before taking enforcement action.

The word "priority" does not mean a debt is more important in a moral or financial sense. It is a classification based on the legal powers available to the creditor and the severity of consequences for the debtor if payment is not made.

• Common priority debts include mortgage or rent arrears, council tax arrears, energy debts (gas and electricity), child maintenance, hire purchase agreements on essential goods, and certain tax debts owed to HMRC.
• Common non-priority debts include credit cards, personal loans, water bill arrears, and most unsecured borrowing.

The classification of debts into priority and non-priority categories is not based on a single piece of legislation. Rather, it reflects the cumulative effect of multiple laws that grant certain creditors stronger enforcement powers than others.

Priority debts are defined by the fact that the consequences of non-payment can be more serious than for other debts. These consequences include the potential loss of a home, the disconnection of essential services such as gas or electricity, or — in a small number of specific circumstances — imprisonment. The defining feature is that the creditor has direct statutory powers to enforce payment without necessarily needing to go through the full county court process that applies to ordinary debts.

Non-priority debts are debts where creditors do not have these extra statutory powers. They cannot directly take a person's home, disconnect essential services, or seek imprisonment. To enforce a non-priority debt, the creditor must typically obtain a court judgment first. This does not mean non-priority debts can be ignored — unpaid debts of any kind can lead to court action, county court judgments (CCJs), and eventual enforcement — but the route to enforcement is longer and the immediate consequences are generally less severe.

It is worth noting that the priority or non-priority status of a debt is determined by the type of debt and the powers attached to it, not by the amount owed or the behaviour of the creditor. A small council tax debt is still a priority debt. A large credit card balance is still a non-priority debt.

Key categories of priority debt

• Mortgage arrears. A mortgage is secured against the property. If payments are not maintained, the lender can ultimately seek a possession order through the courts. FCA-regulated mortgage lenders must follow specific rules when a customer falls into arrears, including providing written details of the arrears within 15 days, not applying excessive pressure, and attempting to reach agreement on repayment. These requirements are set out in the FCA's Mortgages and Home Finance: Conduct of Business sourcebook (MCOB 13). The process leading to repossession is not instant — it involves a defined series of steps including pre-action protocol compliance, a possession claim, a court hearing, a possession order, and a warrant of possession before any eviction can take place. Additionally, since 26 June 2023, signatory lenders to the Mortgage Charter — representing approximately 85% of the mortgage market — have voluntarily agreed not to force customers to leave their home without consent, except in exceptional circumstances, with a 12-month grace period. This is a voluntary commitment rather than a statutory requirement. Complaints about breaches can be made to the Financial Ombudsman Service.

• Council tax arrears. Council tax is a priority debt because local authorities have strong statutory enforcement powers. Under the Council Tax (Administration and Enforcement) Regulations 1992 and the Local Government Finance Act 1992, councils can pursue enforcement through liability orders, attachment of earnings, benefit deductions, bailiff action, charging orders, and — for debts exceeding £5,000 — bankruptcy proceedings. In England only, imprisonment of up to three months is available as a last resort where there is a finding of wilful refusal or culpable neglect to pay. This power does not exist in Wales.

• Child maintenance. The Child Maintenance Service (CMS) has its own set of administrative enforcement powers. These include deduction from earnings orders and deduction directly from bank accounts. Since the Child Support (Enforcement) Act 2023, the CMS can also obtain administrative liability orders without needing to apply to a court, a change that reduced enforcement timelines from approximately six months to approximately six weeks.

• Energy debts (gas and electricity). Energy suppliers can disconnect the gas or electricity supply for non-payment, which is why energy debts are treated as priority debts. The potential for disconnection of an essential service is the consequence that determines their priority status.

• HMRC tax debts. HMRC has enforcement powers that allow it to take control of goods — referred to as distraint in Northern Ireland — without first obtaining a court order. This includes issuing a Notice of Enforcement with a seven-day payment window before enforcement action begins. According to published guidance, HMRC officers cannot force entry to a property without a court order, which is rarely granted. Tools of trade may be exempt from seizure up to a value of £1,350, though this may vary depending on circumstances.

• Hire purchase and conditional sale agreements. These are priority debts because goods obtained under these agreements can be repossessed if payments are not maintained. Under the Consumer Credit Act 1974, the rules around repossession depend on how much has been paid. If less than one-third of the total amount payable has been paid and the goods are not on private land, the creditor can repossess without a court order. Once one-third or more of the total amount payable has been paid — including any deposit or part-exchange value — the goods become "protected goods" and a court order is required for repossession. Selling goods subject to a hire purchase agreement without the creditor's permission is a criminal offence.

Key categories of non-priority debt

• Water bill arrears. Despite being a utility, water bill arrears are classified as non-priority because water companies are prohibited from disconnecting the domestic water supply for non-payment. This prohibition is established under the Water Industry Act 1999 (Section 47) and the Water Industry Act 1991, with Ofwat overseeing compliance. Disconnection is permitted only for non-domestic properties, unoccupied properties, or for safety reasons. Water charges remain payable and enforceable through the county court, but the absence of the disconnection power is what places them in the non-priority category.

• Credit cards, personal loans, and unsecured borrowing. These are non-priority because the creditor holds no security over an asset and has no special statutory enforcement powers. Recovery follows the standard county court route.

Debts that do not fit neatly into either category

Some debts are sometimes described as "square peg" debts — they do not fit neatly into the priority or non-priority framework. According to published guidance, phone and internet debts may be treated as priority in certain circumstances, such as where the service is essential for work, disability needs, or personal safety. Similarly, personal debts owed to family or friends are normally treated as non-priority, but may take on priority characteristics if non-payment risks homelessness — for example, where money is owed to the person whose home the debtor lives in — or where the debt involves domestic or financial abuse. These assessments depend on individual circumstances.

Several specific numerical thresholds and procedural timelines are established in law or regulation. These are set out below.

• Council tax — bankruptcy threshold. A local authority can apply to make a taxpayer bankrupt where the council tax debt exceeds £5,000. New council tax charges continue to apply after the bankruptcy hearing date.
• Council tax — imprisonment (England only). Magistrates can commit a person to prison for up to three months for wilful refusal or culpable neglect to pay council tax. A means enquiry must be held by the court, and the taxpayer must be present. This power is not available in Wales.
• Council tax — loss of instalment rights. After a third missed instalment in the same financial year, the right to pay council tax by instalments is lost.
• Council tax — single enforcement method. A council can only use one enforcement method at a time per liability order.
• Hire purchase — protected goods threshold. Goods become protected once one-third (33.33%) of the total amount payable has been paid. This includes any deposit and part-exchange value. Once goods are protected, a court order is required for repossession.
• Mortgage arrears — FCA notification requirement. A regulated mortgage lender must provide written details of the arrears within 15 days of the customer falling into arrears. This must include missed payments, charges incurred, total amount due, charges that will apply if the arrears are not cleared, and a Money Helper information sheet.
• Child maintenance — deduction from earnings. The CMS can issue a Deduction from Earnings Order requiring the employer to deduct payments. In most cases, the employer can deduct up to £1 as an administration fee per deduction and must comply or face court action. For flat-rate cases involving benefit recipients, the standard deduction amount is £7.35 per week, though this may be subject to change.
• Child maintenance — ultimate sanctions. In cases of persistent non-payment following a liability order, enforcement can escalate to bailiff action, charging orders, driving licence disqualification, passport removal, and in rare cases, imprisonment for up to six weeks (42 days). Imprisonment is regarded as a last resort.
• HMRC enforcement — Notice of Enforcement. After an HMRC Field Force officer visit, a Notice of Enforcement is issued giving seven clear working days to pay before enforcement action proceeds.
• Breathing Space — standard duration. The Debt Respite Scheme provides 60 days of protection from enforcement action for qualifying debts in England and Wales. Interest and charges on qualifying debts are frozen during this period. The scheme came into effect on 4 May 2021.
• Breathing Space — Mental Health Crisis duration. A Mental Health Crisis Breathing Space lasts for the duration of treatment plus 30 days. There is no limit on the number of Mental Health Crisis Breathing Spaces a person can access. This requires confirmation of treatment from an Approved Mental Health Professional.

"Priority" does not mean "pay first." The term "priority debt" is a classification based on the legal consequences of non-payment, not an instruction about which debts to pay in what order. A person may have both priority and non-priority debts, and the approach to managing them depends entirely on individual circumstances. This guide does not provide direction on payment ordering.

Water bills are a utility but not a priority debt. This is one of the most common sources of confusion. Because water companies cannot disconnect the domestic supply for non-payment, water debts lack the enforcement consequence that defines priority debts. This is in contrast to gas and electricity, where disconnection remains possible.

The amount owed does not determine priority status. A council tax debt of £200 is a priority debt. A credit card debt of £20,000 is a non-priority debt. The classification is about the type of debt and the enforcement powers attached to it, not the size of the balance.

Non-priority does not mean unimportant. Creditors of non-priority debts can still pursue court action, obtain county court judgments, and ultimately use enforcement methods such as bailiffs. The process simply requires the creditor to go through the court system first.

Bailiffs and enforcement agents have specific, defined powers. Enforcement agents derive their powers from Schedule 12 of the Tribunals, Courts and Enforcement Act 2007 and the Taking Control of Goods Regulations 2013. Different types of enforcement agent — Certificated Enforcement Agents, High Court Enforcement Officers, and County Court Bailiffs — have different powers.

Arrears on an excluded debt can still qualify for Breathing Space. The Breathing Space scheme excludes certain categories of debt from its protections, including ongoing mortgage payments, ongoing rent, ongoing council tax, ongoing utilities, and secured debts. However, arrears on these debts — as distinct from the ongoing payments themselves — can qualify for Breathing Space protection.

• Geographic variation in council tax imprisonment. Imprisonment for council tax arrears is available in England but not in Wales. The European Court of Human Rights has ruled that committal to prison of an unrepresented person contravenes the Convention. Scotland and Northern Ireland have their own separate enforcement frameworks.
• Geographic variation in Breathing Space. The Debt Respite Scheme (Breathing Space) is currently available only in England and Wales. Northern Ireland held a call for evidence that closed in February 2023 and has a public consultation planned, but its scheme remains in development. Scotland operates separate debt arrangement schemes.
• Joint debts and Breathing Space. Joint debts can be included in Breathing Space even if only one person applies. The protections apply to both parties on the joint debt, but interest can still be charged to the non-applicant. Guarantor loans can be included in Breathing Space, but the protections do not extend to the guarantor.
• Phone and internet debts — conditional priority. In most cases, phone and internet debts are treated as non-priority. However, according to published guidance, they may be treated as priority where the service is essential for work, disability needs, or personal safety. This assessment depends on individual circumstances.
• Family and friend debts — conditional priority. Personal debts owed to family or friends are normally non-priority. However, they may take on priority characteristics where non-payment risks homelessness or involves domestic or financial abuse. This may vary depending on the specific circumstances.
• Hire purchase — criminal offence. Selling goods that are subject to a hire purchase agreement without the creditor's permission is a criminal offence under the Consumer Credit Act 1974. This is distinct from the civil consequences of missed payments.
• Mortgage Charter — voluntary, not statutory. The Mortgage Charter agreed from 26 June 2023 is a voluntary commitment by signatory lenders, not a legal requirement. It covers approximately 85% of the mortgage market. Its protections apply only to borrowers with signatory lenders.
• Breathing Space — eligibility exclusions. A person cannot access Breathing Space if they are an undischarged bankrupt, currently subject to a Debt Relief Order (DRO) or Individual Voluntary Arrangement (IVA), subject to an interim order, or already in a Breathing Space. They must be an individual resident in England or Wales with qualifying debts where payments cannot be met.
• Breathing Space — cancellation. A Breathing Space can be cancelled before its 60-day duration expires if the debtor does not engage with debt advice or work towards a debt solution.

The distinction between priority and non-priority debt determines the enforcement tools available to a creditor and, by extension, the speed and severity of consequences that can follow non-payment.

For priority debts, the enforcement process often begins earlier and involves powers that do not require a separate court judgment. A council can obtain a liability order from a magistrates' court relatively quickly. The CMS can issue a Deduction from Earnings Order administratively. A mortgage lender, while subject to FCA rules and the pre-action protocol, can ultimately seek possession through the courts.

The council tax enforcement process follows a defined sequence: reminder notice, second reminder if applicable, final notice, summons (issued at least 14 days before the hearing), liability order, and then enforcement action. After three missed instalments in the same financial year, the right to pay by instalments is lost. Each step narrows the options available.

For mortgage arrears, the process involves lender contact and arrears notification, compliance with pre-action protocol steps, a possession claim, a court hearing, a possession order, a warrant of possession, and finally eviction. The FCA requires lenders to have a written policy on arrears handling and to attempt agreement on repayment before pursuing possession.

For non-priority debts, creditors must generally obtain a county court judgment before enforcement action becomes available. This provides an additional step in the process that is not required for many priority debts.

The Breathing Space scheme offers a structured form of temporary protection. Where it applies, it provides 60 days of relief from enforcement action and freezes interest and charges on qualifying debts. This is accessed through a debt adviser who assesses eligibility. The Mental Health Crisis variant lasts for the duration of treatment plus 30 days and can be accessed without limit on the number of times. However, the debtor must engage with debt advice during the Breathing Space period and work towards a debt solution, or the protection can be cancelled.

What makes a debt "priority"?

A debt is classified as priority based on the consequences of non-payment. Priority debts are those where the creditor has statutory powers that can lead to the loss of a home, disconnection of essential services, or in limited circumstances, imprisonment. The classification has nothing to do with the amount owed.

Are water bills a priority debt?

No. Water companies are prohibited from disconnecting the domestic water supply for non-payment under the Water Industry Act 1999 (Section 47). Because disconnection is not a possible consequence, water bill arrears are classified as non-priority. Water charges remain enforceable through the county court.

Can you go to prison for not paying council tax?

In England, magistrates can commit a person to prison for up to three months for wilful refusal or culpable neglect to pay council tax, but only after a means enquiry has been held and only where bailiff action has been unable to recover the debt. This power does not exist in Wales.

What happens if you miss hire purchase payments?

The consequences depend on how much has been paid. If less than one-third of the total amount payable has been paid and the goods are not on private property, the creditor can repossess without a court order. Once one-third or more has been paid — including deposit and part-exchange value — the goods are "protected" and repossession requires a court order.

What is Breathing Space?

The Debt Respite Scheme (Breathing Space) provides 60 days of protection from enforcement action in England and Wales. During this period, interest and charges on qualifying debts are frozen. It is accessed through a debt adviser and requires the debtor to engage with debt advice during the protection period. A Mental Health Crisis Breathing Space lasts for the duration of treatment plus 30 days.

Does Breathing Space cover all debts?

No. Certain debts are excluded, including secured debts, child maintenance, student loans, Universal Credit advances, fraud debts, ongoing council tax, ongoing rent or mortgage payments, ongoing utilities, ongoing taxes and National Insurance contributions, VAT from business, and personal injury damages. However, arrears on some excluded debts — such as mortgage or rent arrears — can be qualifying debts, even though the ongoing payments are not covered.

Can the CMS take money directly from wages?

Yes. The CMS can issue a Deduction from Earnings Order without a court order. The employer must comply or face court action. The employer can deduct up to £1 as an administration fee per deduction.

Do the rules differ across the UK?

Yes, in several important ways. Imprisonment for council tax arrears is available in England but not Wales. The Breathing Space scheme applies only in England and Wales; Northern Ireland's equivalent is still in development, and Scotland has its own separate debt arrangement schemes. HMRC enforcement uses different terminology in Northern Ireland (distraint rather than taking control of goods).

• Priority and non-priority debt classification in the UK is determined by the legal consequences of non-payment, not by the amount owed, the type of creditor, or the urgency of collection activity.
• Priority debts carry the risk of the most severe consequences — potential loss of home, disconnection of essential services, or in specific limited circumstances, imprisonment. Creditors of priority debts often have statutory enforcement powers that do not require a court judgment.
• Non-priority debts require creditors to obtain a court judgment before enforcement action can proceed. The consequences of non-payment are serious but follow a longer route to enforcement.
• Some debts — such as phone and internet bills, or debts to family and friends — do not fit neatly into either category and may be treated as priority or non-priority depending on individual circumstances.
• The rules vary across the UK. Council tax imprisonment is available in England but not Wales. The Breathing Space scheme applies only in England and Wales. Scotland and Northern Ireland have their own frameworks.
• The Breathing Space scheme provides temporary protection — 60 days for standard cases, or the duration of treatment plus 30 days for Mental Health Crisis cases — but requires engagement with debt advice and excludes certain categories of debt.
• Water bill arrears are non-priority because domestic water supply cannot be disconnected for non-payment.
• Hire purchase goods become "protected" once one-third of the total amount payable has been paid, after which repossession requires a court order.
