Judges in the UK work across a tiered court system that runs from unpaid lay magistrates in local courthouses up to the twelve Justices of the Supreme Court in London. They are chosen on merit by independent commissions after years of legal practice, decide criminal and civil cases under statutory guarantees of independence, and are paid on a published scale that reaches £234,096 for a High Court judge. Because the United Kingdom contains three separate legal systems — England and Wales, Scotland, and Northern Ireland — court names and some procedures vary, but the principles of merit selection and judicial independence apply everywhere.
The Types of UK Judges
Judicial titles in the UK map directly onto where in the court system a judge sits and what kind of cases they hear.
Justices of the Supreme Court
At the top sit the Justices of the Supreme Court, the final court of appeal for the whole United Kingdom on points of law of general public importance. The court has a statutory maximum of 12 justices, though the monarch may increase that number by Order in Council.1Legislation.gov.uk. Constitutional Reform Act 2005 They usually hear cases in panels of five, and their rulings bind every lower court. The Constitutional Reform Act 2005 created the court to replace the old Appellate Committee of the House of Lords, making the separation between Parliament and the judiciary visible rather than theoretical.2The Supreme Court of the United Kingdom. The Court and Legal System
Lords Justices of Appeal and High Court Judges
Lords Justices of Appeal sit in the Court of Appeal and review decisions from lower courts in both criminal and civil matters. Below them, High Court Judges handle the most complex first-instance work in three divisions: the King’s Bench Division (general civil claims, judicial review, and some criminal appeals), the Chancery Division (business disputes, insolvency, intellectual property, and trusts), and the Family Division (divorce, child custody, and inheritance).3Courts and Tribunals Judiciary. Structure of Courts and Tribunals System
Circuit Judges, Recorders, and District Judges
Circuit Judges carry the mid-level criminal and civil load, sitting in the Crown Court for serious criminal trials and the County Court for larger civil claims. Recorders do the same work part-time, often as a step toward a full-time judicial post. District Judges run the highest volume of day-to-day business in the County Court and, in some locations, the magistrates’ courts, dealing with smaller money claims, housing cases, family applications, and preliminary criminal hearings.
Magistrates
Magistrates sit at the most local level and differ from every other judge in one fundamental respect: they are unpaid volunteers drawn from the community, not professional lawyers.4GOV.UK. Become a Magistrate Cases are normally heard by a panel of three, one of whom is trained to chair. They handle over 95% of criminal cases in England and Wales, covering offences from shoplifting and traffic violations to assault and low-level drug possession.5Courts and Tribunals Judiciary. Criminal Their sentencing powers are capped, generally at six months’ custody for a single offence, so more serious cases are sent up to the Crown Court.
Tribunal Judges
Running alongside the courts is a separate tribunal system where salaried tribunal judges resolve disputes between individuals and government bodies — tax assessments, immigration decisions, disability benefit refusals, mental health detentions, and more. Decisions of the First-tier Tribunal can be appealed to the Upper Tribunal, which sits at a level equivalent to the High Court.6Courts and Tribunals Judiciary. First-tier Tribunal Tribunal judges are selected under the same merit-based framework as court judges.
Who Can Become a Judge
Two gates stand in front of every candidate: professional experience and citizenship.
Every applicant must hold a legal qualification as a barrister or solicitor and must have spent a minimum number of years working in law. District judges, tribunal judges, and most specialist court masters need five years of post-qualification experience. Circuit judges, recorders, High Court judges, and Lords Justices of Appeal need seven.7Legislation.gov.uk. Tribunals, Courts and Enforcement Act 2007 The Tribunals, Courts and Enforcement Act 2007 counts any time spent “gainfully occupied in law-related activities,” so academic lawyers, in-house counsel, and government legal advisers can qualify alongside private practitioners.8Legislation.gov.uk. Tribunals, Courts and Enforcement Act 2007
Candidates must also be a citizen of the United Kingdom, the Republic of Ireland, or a Commonwealth country at the time of application. Dual nationals holding one of these citizenships are eligible, and the rule applies at every level from part-time tribunal posts to the Supreme Court.9Judicial Appointments Commission.

How Judges Are Selected
No politician in the UK picks judges. Each legal system has an independent commission that selects candidates on merit, and the process is deliberately slow and thorough so that political patronage never gains a foothold.
England and Wales
The Judicial Appointments Commission (JAC) handles selection for courts and tribunals in England and Wales. The Constitutional Reform Act 2005 requires the JAC to appoint solely on merit and to confirm that every candidate is of good character.1Legislation.gov.uk. Constitutional Reform Act 2005 When a vacancy arises, the JAC advertises the role, collects applications and references, and puts candidates through a combination of written tests, interviews, and courtroom simulations with professional actors depending on the post.11Judicial Appointments Commission. Guide to JAC Selection Processes The JAC then forwards its recommended candidate to the Lord Chancellor, who may reject or request reconsideration but cannot substitute a different name. If the recommendation is accepted, the monarch formally makes the appointment.
Good character is treated broadly. Criminal convictions, regulatory findings, current driving endorsements, tax irregularities, and insolvency history must all be disclosed, including anything that happened outside the UK, and failure to disclose is itself treated as evidence of unsuitability. The JAC runs its own checks with the ACRO Criminal Records Office, HMRC, the Insolvency Service, and the candidate’s professional regulator before any appointment is confirmed.12Judicial Appointments Commission. Good Character Guidance
Scotland and Northern Ireland
Scotland’s Judicial Appointments Board carries out the equivalent function for Scottish courts and tribunals, advertising vacancies, assessing applications, and recommending candidates to the First Minister. Northern Ireland has its own Judicial Appointments Commission (NIJAC), established in 2005, which selects and recommends candidates up to and including High Court level and carries a statutory duty to work toward a judiciary that reflects the community.13Northern Ireland Assembly. Review of Judicial Appointments in Northern Ireland – Background Paper All three commissions share the same foundational principle: merit alone, free from political interference.
Supreme Court Appointments
The Supreme Court uses its own process. When a vacancy arises, an ad hoc selection commission is convened. For a regular justice, it is chaired by the President of the Supreme Court and includes one senior UK judge from outside the court plus representatives from the three national judicial appointments bodies, at least one of whom must be a non-lawyer. For the President of the Supreme Court, the commission is instead chaired by the non-lawyer member.14The Supreme Court of the United Kingdom. Supreme Court Selection Process The commission advertises the post, consults senior judges and political leaders across the UK (including the Lord Chancellor, the First Ministers of Scotland and Wales, and NIJAC), and interviews candidates. If two candidates are of equal merit, the commission may pick the one who would improve the court’s diversity. The Lord Chancellor may accept, reject, or request reconsideration, but cannot propose an alternative.
What Judges Do
Day-to-day work splits along the criminal/civil line. In criminal trials, the judge controls the courtroom, rules on the admissibility of evidence, and directs the jury on the applicable law and the standard of proof. After a guilty verdict, the judge passes sentence within the range set by statute and sentencing guidelines, which can run from a community order or fine to life imprisonment for the most serious offences. The guidelines provide a framework, not a formula, and the judge has to weigh the specifics of the offence against the circumstances of the defendant.
Civil work calls for different skills. There is usually no jury; the judge alone decides liability and remedy. Disputes over contracts, property, personal injury, and family matters are all resolved here. Judges interpret legislation and prior rulings to decide who owes what to whom, and they can award damages, grant injunctions, or order specific performance of a contract. In commercial litigation the sums at stake can run into hundreds of millions of pounds, and a single ruling can reshape how an entire industry operates.
How Judicial Independence Is Protected
The idea that judges must be free to decide cases without political pressure is old, but it was written into statute only in 2005. Section 3 of the Constitutional Reform Act 2005 puts a legal duty on the Lord Chancellor, every other government minister, and anyone with responsibility for the administration of justice to uphold the continued independence of the judiciary. The Lord Chancellor must also actively defend that independence and ensure the judiciary has the resources it needs. Section 4 extends the same duty in respect of the judiciary in Northern Ireland.1Legislation.gov.uk. Constitutional Reform Act 2005
Three practical protections give that principle teeth. First, security of tenure: a judge cannot be dismissed for an unpopular ruling. Senior judges of the High Court and Court of Appeal can be removed only through an Address of both Houses of Parliament to the monarch, a power originating in the Act of Settlement 1701 and now contained in section 11(3) of the Senior Courts Act 1981. No English judge has been removed this way in modern history.15Courts and Tribunals Judiciary. Judges and Parliament Second, judicial immunity: judges cannot be sued for anything said or done while carrying out their judicial functions, which protects them from retaliatory litigation by unhappy parties. Third, financial security: judicial salaries are charged on the Consolidated Fund, so they do not depend on annual votes in Parliament, a deliberate design to stop the government from using pay as leverage.
Complaints and Removal
Independence does not put judges beyond scrutiny. The Judicial Conduct Investigations Office (JCIO) handles complaints about the personal conduct of judges, tribunal members, and coroners in England and Wales. Anyone can file one. But the JCIO looks only at personal misconduct — rudeness, bias, unjustified delay, inappropriate behaviour — and cannot overturn a legal decision. The remedy for a wrong ruling is an appeal.
Complaints are triaged by JCIO staff and investigated if they raise a genuine concern. If upheld, the Lord Chancellor and the Lord Chief Justice can jointly issue sanctions ranging from formal advice or a reprimand through to removal from office for lower-tier judges. For High Court judges and above, removal still requires the parliamentary Address process; the JCIO route alone cannot accomplish it.
Judicial Pay and Retirement
Judicial salaries are set following recommendations from the Senior Salaries Review Body, an independent panel. For the 2025–26 financial year, annual salaries for the main court roles in England and Wales are:
- High Court Judge: £234,096
- Circuit Judge: £173,854
- District Judge: £139,469
Salaries for Court of Appeal judges and Supreme Court justices are higher but were not published in the same schedule.16GOV.UK. Ministry of Justice Evidence: Major Review of the Judicial Pay Magistrates serve without pay. They can claim travel expenses and a loss-of-earnings allowance, but the role is fundamentally voluntary.
The mandatory retirement age for judges, magistrates, and coroners across the UK was raised from 70 to 75, the first change to these rules in nearly three decades.17GOV.UK. Judicial Retirement Age to Rise to 75 The change was driven partly by recruitment difficulties, with experienced lawyers in their mid-sixties declining appointments because the service window was too short to justify leaving a lucrative practice. After reaching retirement age, judges may still be invited to sit on a fee-paid basis, handling individual cases without holding a permanent post.
