King's Counsel (KC) explained. What it means and how barristers become one.

If you've read about a court case and seen "KC" after a barrister's name, you might have wondered what it means. Or you've sat down with a solicitor who says your case needs a KC, and the price tag made you flinch. King's Counsel is a real rank in the UK legal profession. It's not just a title, and it's not automatic. It represents something concrete: formal recognition that a barrister has become an expert in their field.

For most of history this was called "Queen's Counsel" (QC). When Queen Elizabeth II died in 2022, the title changed to King's Counsel (KC). The rank itself stayed the same. Everything below is what that rank means, how barristers get it, and whether you actually need one.

The short version

A King's Counsel is a senior barrister who has been formally appointed to that rank by an independent panel. They are usually the most experienced courtroom advocates available, often with 15 or more years at the bar. Being made a KC is highly competitive. About 1 in 8 applicants succeed each year. It's a significant career achievement.

KCs charge more than junior barristers. A senior KC might charge £600 to £3,000 per hour, compared to £200 to £600 for a junior barrister with less experience. Whether you need one depends on the complexity of your case and the stakes involved. For routine cases, a junior barrister or a solicitor is usually enough. For serious commercial disputes, major criminal trials, or appeals to higher courts, a KC often makes the difference.

At a glance

What does KC actually stand for

KC stands for King's Counsel. It is the formal rank given to senior barristers who have been appointed by the King's Counsel Appointments panel.

Until 2022 this was Queen's Counsel, abbreviated QC. The change to KC happened automatically when Queen Elizabeth II died and King Charles III became monarch. No QCs were re-examined or had to apply again. They all became KCs overnight. Any barrister who had been appointed QC before 2022 is now a KC.

The history

Senior barristers have held a special rank since at least 1597 under Elizabeth I. It used to mean a barrister who was employed by the Crown as a "counsel" or advisor. The term "King's Counsel" became formalised in the 1500s as a way to mark the most senior advocates.

The reason they're sometimes said to have "taken silk" is historical. Senior barristers wore robes made of silk, which was more expensive than the wool used for junior barristers' robes. So "taking silk" became the phrase for becoming a senior barrister. You'll still hear this today. A barrister might say "I took silk in 2010" to mean they were appointed as a QC in 2010 (and are now a KC).

The rank changed from QC to KC in September 2022, a few weeks after the Queen's death. It was the only title-related change. The process for becoming one stayed the same.

What it means today

A KC is a senior barrister. That's it in one sentence.

The implications are worth unpacking though. If someone is a KC, it means:

They have been formally assessed and recognised as an expert in their field. The appointment is competitive and independent, not automatic based on years served. A barrister can have 25 years of experience and never be appointed KC if they haven't been selected. Conversely, some fast-track barristers make KC in their early 40s if they have the right experience.

They charge significantly more. Most junior barristers work from chambers on a semi-employed model. Their fees reflect their experience level, usually a few hundred pounds per hour. A KC's fees often start at £600 per hour and can reach £3,000 or more depending on their specialism and reputation.

They take on the most complex cases. While junior barristers do substantial work, KCs are brought in for the cases that hinge on difficult legal points, complex facts, or high stakes. In criminal law, a KC might be instructed for a murder trial or a major fraud case. In commercial law, a KC might handle mergers worth hundreds of millions of pounds.

They are more likely to be heard by appellate judges. If a case goes to the Court of Appeal or Supreme Court, the barristers arguing it are very often KCs. Some appeal cases are almost exclusively KC-led.

They have higher visibility. The most reported court cases, the ones you read about in the news, are usually argued by KCs. This builds their reputation and brings more work.

How to become a KC

Becoming a KC is a three-stage process: you have to be a barrister already, you have to apply, and you have to be appointed by an independent panel.

Step 1: Become a barrister

This takes a minimum of about three to four years after your law degree. You do a law conversion course if you didn't study law at university, then the Bar Practice Course, then pupillage (a one-year apprenticeship), then you are called to the Bar. After that you are a junior barrister. You cannot be a KC without first being a called barrister.

Step 2: Build experience

There is no strict minimum, but in practice most KCs have 10 to 20 years' call before they apply. This is experience arguing cases, writing opinions, building a reputation as an expert. The Bar Council publishes the typical profile of someone who applies for KC: a barrister with about 15 years' experience, a track record of instructions in complex cases, and strong references from judges and other barristers.

Some barristers never apply. They are perfectly happy as seniors without the KC title. Some deliberately wait longer than is necessary because they know the competition is fierce. Some apply multiple times before they succeed.

Step 3: Apply to KC Appointments

KC Appointments is the independent body that runs the process. It opens applications once a year, usually in the spring. The application involves:

• Filling out a detailed form that asks about your experience, cases you have handled, areas of law, and why you deserve to be a KC.
• Supplying references from judges and other barristers who have worked with you.
• Paying an application fee of around £3,800 (as of 2024).
• Attending an interview with the selection panel if you make the first cut.

The panel is made up of judges, KCs, and experienced barristers. They assess candidates on competence, independence, integrity, and commitment to justice.

Step 4: Wait for the appointment

KC Appointments publishes results once a year, usually in the autumn. If you are successful, you are appointed with effect from the next date specified by the King's Counsel Appointments office.

If you are not successful, you can apply again the following year. Most successful applicants are not appointed on their first attempt. The competition is real. In recent years, about 1 in 8 applications have been successful, which means roughly 150 to 200 barristers become KCs each year out of around 1,500 to 2,000 who apply.

The numbers

There are roughly 1,800 KCs in England and Wales today. There are roughly 17,000 barristers in practice overall. That means about 1 in 10 barristers holds KC status.

The number has been growing slowly. In the 1990s there were fewer KCs, around 1,200 to 1,400. The profession has consciously broadened the appointment process since then to make it more transparent and less dependent on the old informal networks. The annual appointment rate has increased over the last 20 years from around 50 to 80 new KCs per year, to somewhere between 150 and 200 today.

Women and barristers from ethnic minorities are significantly under-represented among KCs. The profession is aware of this and KC Appointments has made efforts to level the playing field. The composition is slowly changing but there is still an imbalance.

The application process in more detail

Once you decide to apply, here's what happens:

You download the application pack from the KC Appointments website and fill it out. The form asks for detailed information about your practice: how many cases you have done, what types of law, which courts you have appeared in, which judges have worked with you. You also explain why you deserve to be a KC. This essay is important. Some applicants write about their expertise, others about service to the profession, others about ambition to serve justice at a higher level.

You identify referees. These are usually judges you have appeared before, other KCs or senior barristers, and sometimes solicitors who instruct you regularly. You need to ask them to submit confidential references to KC Appointments. They do this directly, not through you.

You pay the fee (currently around £3,800). This is non-refundable even if you do not make the cut.

You submit the application by the deadline, usually in May or June.

KC Appointments staff review all applications and do a preliminary filter. Many applications will be rejected at this stage if they do not meet a basic threshold of experience or quality.

If you pass the preliminary stage, you are invited to attend an interview. The interviews happen over several weeks in the summer. You typically have two hours with the panel, which might be a judge, a KC or two, and a senior barrister. They ask questions about your experience, your judgment, your understanding of your role as a KC, and your commitment to the profession. The interview can be tough. Some applicants report being asked sharp questions designed to test how you handle challenge.

After all interviews are completed, the panel deliberates and produces a ranked list of successful candidates. This is usually kept confidential until the public announcement, which happens in the autumn, usually in September or October.

Successful candidates are notified in advance of the public announcement. They are then formally appointed as KC by ceremony or proclamation. In recent years this has been a formal announcement rather than a public ceremony, though the appointment is real and binding.

Unsuccessful candidates receive no feedback other than that they were not appointed. Some panels provide written feedback if asked, but this is not guaranteed.

How much KCs charge

A junior barrister with a few years' experience charges anywhere from £200 to £600 per hour, depending on their specialism and location. A barrister with 10 to 15 years' experience and a strong reputation might charge £400 to £800 per hour.

A KC typically charges a minimum of £600 per hour, and can go much higher. A very senior KC with a world-class reputation in a niche specialism (complex commercial law, for instance, or major criminal trials) might charge £1,500 to £3,000 per hour or more.

Some KCs charge fixed fees for defined pieces of work. For instance, a KC might charge a fixed fee of £10,000 to £30,000 to write an opinion on a legal point, or £50,000 to £100,000 to lead a trial.

In a serious case, instructing a KC can easily cost tens of thousands of pounds. A trial led by a KC might cost £100,000 to £250,000 just for the barrister, plus the solicitor's costs on top.

This is one reason many litigants in person (people representing themselves) are now half of all parties in civil court cases in the UK. Many cannot afford to instruct a barrister or a solicitor at all.

When you actually need a KC

Not every case needs a KC. Most do not.

You might need a KC if:

• Your case is going to a trial in the High Court or above. A KC's courtroom experience is invaluable for high-stakes cases.
• The law is genuinely uncertain or complex. If the case turns on a difficult legal point where there isn't clear precedent, a KC's specialist opinion can be decisive.
• The other side has instructed a KC. If they have brought in heavy firepower, matching them with a KC of your own is often wise.
• You are appealing a decision to the Court of Appeal or Supreme Court. Appellate work is almost always KC-led.
• It is a serious criminal case. Murder trials, major fraud, serious assault, high-value drug cases. The Crown Prosecution Service often instructs KCs for serious crime.
• The case has enormous financial stakes. A billion-pound commercial dispute justifies the cost of a KC.
• You want a second opinion on the strength of your case. Some solicitors brief a KC simply to get their assessment of whether to fight or settle.

You almost certainly do not need a KC if:

• Your case is a straightforward small claims matter.
• It is a routine traffic case or minor criminal matter.
• You are buying or selling a house.
• You have a simple employment dispute or breach of contract that is clearly in your favour.
• The amount at stake is relatively small (under £25,000 to £50,000).

Your solicitor will advise you on whether a KC is necessary. If you are unsure, ask them to justify it. A good solicitor will only brief a KC if the case genuinely needs one. A bad one might overcharge by suggesting a KC for routine work. The decision is yours, but the solicitor's advice matters.

Day to day

The day-to-day life of a KC looks similar to that of a junior barrister, just with more high-stakes work and more money.

A KC might spend the morning in the Court of Appeal or High Court cross-examining a witness or arguing a complex legal point to a judge. In the afternoon they return to chambers and read 300 pages of evidence in preparation for tomorrow's hearing. In the evening they write a Skeleton Argument (the formal summary of their legal position) or an Opinion on a point of law.

They also manage their reputation. A KC is often the face of a case to the media, the court, and other lawyers. Senior judges know KCs by name and reputation. Other barristers and solicitors instruct them based on past performance. A KC is careful about which cases they take, because each case adds to or detracts from their reputation.

Some KCs do more negotiation and settlement work than junior barristers, though this varies widely. Some are courtroom warriors who live for trial work. Others are happier writing opinions and advising behind the scenes.

KCs also mentor junior barristers. Chambers depend on KCs to train the next generation. Many KCs have pupils of their own or supervise young barristers' work.

Common misconceptions

"All KCs are better lawyers than non-KCs." Not exactly. A KC is a senior advocate with a track record of success in complex cases. But they are only better than others within their own specialism. A KC in commercial law might be an average criminal advocate. A KC with 20 years' experience in housing law might be less skilled than a non-KC with 10 years' niche expertise in personal injury. KC status means "recognized expert in this field", not "best lawyer in the country".

"You need a KC for any case that goes to court." No. Most cases that go to the County Court or District Court are successfully handled by junior barristers or solicitors with rights of audience. You need a KC when the case is complex, high-stakes, or legally uncertain.

"KCs are more expensive because they work harder." They are more expensive because they are more experienced, more in demand, and can command higher fees because clients believe they will win. Whether they work harder is debatable.

"Every KC was brilliant at school." No. Many KCs are extremely bright, but so are many non-KCs. KC appointment is based on demonstrated performance at the bar, not on educational background.

"KCs are all from privileged backgrounds." The profession is still skewed toward Oxbridge and independent schools, but this is changing. In recent years KC Appointments has actively tried to broaden the field to recognize talent from all backgrounds.

"Women cannot become KCs." False. Women are appointed as KCs every year. They are under-represented (about 25 to 30 percent of newly appointed KCs are women, while women make up about 35 to 40 percent of the profession), but they are appointed.

"Once you are a KC you never lose the title." True. If a KC is struck off the Bar for misconduct they lose their right to practice, but the title "KC" is formally removed. In normal circumstances a KC keeps the title for life.
