At its harbour and airport Guernsey must apply United Kingdom immigration law and may set no controls of its own, yet it decides for itself who may live in most of its houses, through a register that splits homes into a local market and a small open market. The same line runs through the whole Bailiwick. It is a self-governing Crown Dependency, separate from the United Kingdom without being independent of it: London answers for defence, foreign representation and nationality, and the island keeps its Norman customary law, its taxes, its own pound notes and its parliament. Guernsey had 67,787 people as of 1 January 2024, on a Bailiwick of 78 square kilometres off the coast of Normandy.

Where Guernsey stands between Crown and kingdom
The Bailiwick of Guernsey is a self-governing Crown Dependency. It is separate from the United Kingdom and forms no part of it, and it is not independent of it either. The island's government variously calls the British monarch its "Head of State" or the "successor to the Duke of Normandy", and no document defines the islands as a monarchy. The Channel Islands were never absorbed into England by any Act of Union; they exist, in Wikipedia's phrase, as "peculiars of the Crown". Islanders have never had formal representation in the House of Commons.
Nothing sets the division of powers down in one document. Guernsey's constitution is unwritten, confirmed piecemeal by successive monarchs, and the Bailiwick's governments have generally avoided testing its limits by avoiding conflict with British governments. What can be listed is where each matter is decided in practice.
| Decided in the Bailiwick | Decided in London |
|---|---|
| Domestic law, made by the States of Deliberation | Defence |
| Income, company and property taxes | Formal international and consular representation |
| Courts founded on Norman customary law | Nationality law |
| Sterling notes and coins of Guernsey's own issue | Immigration law, extended to the island by Order in Council |
| The postal service, run locally since 1969 | Royal assent to primary legislation, through the Privy Council |
Behind the whole list sits an ill-defined reserved power, kept by the Crown and exercised in practice by the UK Government, to intervene in the domestic affairs of any Crown Dependency "in the interests of good government".
The Bailiwick is itself three jurisdictions. Guernsey, taking in Herm, Jethou and Lihou, is the legal and administrative centre. Alderney has its own States and Sark its Chief Pleas, and each of the three needs royal assent for its primary legislation, although since 29 February 2024 certain domestic laws need only the assent of the Lieutenant Governor. Alderney gave its taxing rights to Guernsey in 1949.
How a fragment of Normandy stayed with England
The islands came under the Duchy of Normandy in 933, under William Longsword, and their dukes became kings of England from 1066. When King John lost mainland Normandy to Philip II of France in 1204, the islands stayed with the English Crown, and the Treaty of Paris of 1259 recognised them as Henry III's. Wikipedia describes the Bailiwick as the last remnant of the medieval duchy.
Loyalty was paid for in privileges. A charter of Richard II in 1394 exempted the islanders for ever from English tolls, customs and duties. A papal bull of 1483 declared the islands and their seas neutral "as far as the eye can see", a royal charter confirmed it in 1548, and the neutrality lasted another century, when William III abolished it over privateering against Dutch ships.
On 15 June 1940 the British government decided the Channel Islands would not be defended. From 30 June 1940 German troops occupied the island, after some 17,000 people had been evacuated to England, among them 80% of Guernsey's children, and the occupiers deported over 1,000 residents to camps in southern Germany. Liberation came on 9 May 1945. Guernsey: history follows the whole sequence, from the Norman fiefs to the rebuilding after 1945.
What the islands of the Bailiwick are made of
Britannica gives the island of Guernsey 62 square kilometres and the Bailiwick 78. The island is a rough triangle. Its south is a plateau of about 90 metres ending in ragged cliffs; its north is low ground of blown sand, raised beaches and the fill of old lagoons, broken by small outcrops of hard rock called hougues. The northern tip, the Clos du Valle, was a tidal island before Le Braye du Valle was drained in 1806.
A tidal range of 10 metres and currents of up to 12 knots make local sailing dangerous. The climate is maritime, with snow and severe frost rare and an annual temperature range of only about 9°C by Britannica's figure. The highest point in the Bailiwick is Le Moulin on Sark, at 114 metres. Its landscape takes up the rock and the flooded quarries that now store the island's water.
How the States govern Guernsey by committee
The States of Deliberation is the island's parliament and, through its committees, its government. It sits as one chamber of 38 People's Deputies and two representatives from Alderney, with the Bailiff presiding. The Bailiff is a Crown appointment and also heads the judiciary, so one office chairs the legislature and the Royal Court.
There is no cabinet. Committees of the States run the departments, and on 1 May 2016 the Policy and Resources Committee replaced the Policy Council, its president becoming the de facto head of government. Elected deputies date from 1899, when nine were added to the States. Since 2020 all 38 are chosen by the whole island at once: the first island-wide election, in October 2020, drew a turnout of 80%, and the June 2025 election drew 72%.
A law passed by the States takes legal effect only once His Majesty in Council approves it at a meeting of the Privy Council in London, after which it returns to be registered at the Royal Court. Guernsey: politics explains why the island kept government by committee when Jersey gave it up.
Who may live in Guernsey's houses
The border is where the Bailiwick's separateness runs out. For immigration and nationality, UK law applies, the Immigration Act 1971 extended by Order in Council, and Guernsey may not apply controls of its own. The island lies inside the Common Travel Area. Since 1 January 2021, EU nationals other than British or Irish ones need a visa to come for anything other than a visit, and anyone arriving to work needs a visa and a Population Management document.
What Guernsey controls instead is who occupies its housing. Homes are split into local market properties, which only qualifying residents may occupy, and a set number of open market properties that anyone may live in, and the open market ones cost much more to buy and to rent. A housing licence is often valid for only four years, is tied to a named employer, and names the address. Ownership is unrestricted. A person whose licence expires may keep a Guernsey property and still lose the right to live in it.
Local status is generally earned by being born to at least one Guernsey parent and living on the island for ten years in a twenty-year period, and once gained it lasts for life. The current law is the Population Management (Guernsey) Law of 2016, in force from April 2017. In the year to December 2019 net migration added 563 people, against an assumed long-term average of 100 a year, by the States' Economic Overview of December 2020.
What Guernsey earns from having its own laws
Guernsey's GDP was estimated at £3,488 million for 2023, or £54,463 a head. Financial and insurance activities produced £1,304 million of that, 37% of the total. Banks began arriving in the early 1960s to avoid onshore taxes and regulation, and the net asset value of Guernsey funds stood at £270.0 billion at the end of the second quarter of 2026, by the Guernsey Financial Services Commission's count.
Most of that follows from the tax code. Since 2008 most companies pay corporation tax at 0%, banking and some insurance and fiduciary business at 10%, and regulated utilities and income from land at 20%. Residents pay income tax at 20% on worldwide income, and the island levies no capital gains, inheritance or value added tax. Guernsey has no central bank and issues its own sterling notes and coins, which circulate beside UK money.
Horticulture collapsed after the oil price rises of the 1970s, and the States' Economic Overview of December 2020 put agriculture, horticulture, fishing and quarrying together at 0.2% of GDP in 2019. Guernsey: economy works through the national accounts and the finance sector's divisions.
Which languages Guernsey speaks and keeps
English is the principal language for most inhabitants, and the States and the courts work in it. Beneath it lies Guernésiais, the island's Norman French. The 2001 census counted 1,327 fluent speakers, and a States committee estimated in 2020 that between 50 and 200 native speakers remained. Guernésiais and French were recognised as official languages in August 2020.
The French connection has other forms. Victor Hugo lived in exile at Hauteville House in St Peter Port from 1855 to 1870 and wrote Les Misérables there; the house now holds the French Consulate. The island gave its name to a breed of fawn and white dairy cattle, kept mostly on the southern high ground. Liberation Day falls on 9 May each year. Guernsey: culture traces the three languages and what the evacuation of 1940 did to them.
How visitors reach an island its government supplies
The States own Guernsey's airport at La Villaize, in the parish of Forest, its two main harbours and, since 15 May 2003, the airline Aurigny, bought to protect the island's air links. In 2025 some 533,253 people travelled to or from Guernsey, and the States counted 282,028 of them as visitors. Visitor spending between April 2025 and March 2026 was estimated at £149 million, 72% of it from visitors from the UK.
Guernsey has drawn tourists since at least 1834, when the first guide to the island was published, and two railway companies once raced competing boats from the UK to St Peter Port. Guernsey: travel covers the routes in and the boats on to Sark.

Common questions
Questions about Guernsey
Is Guernsey part of the United Kingdom?
No. The Bailiwick of Guernsey is a self-governing Crown Dependency, separate from the United Kingdom, and its people have never had formal representation in the House of Commons. It is not independent either: the UK Government answers for its defence, its formal international representation and its nationality law, and the States' laws take effect once the Privy Council in London has approved them.
Do Guernsey residents need permission to live in a particular house?
Most do. Local market properties may be occupied only by people who qualify, through birth to a Guernsey parent and ten years' residence in twenty, through a housing licence, or by living with someone who qualifies. Open market properties, of which there is a set number, are open to anyone and cost much more.
What currency is used in Guernsey?
The pound sterling. Guernsey has no central bank, but the States issue their own sterling notes and coins, and UK coins and notes circulate beside them interchangeably.
What does the Bailiwick of Guernsey include?
Three jurisdictions. Guernsey itself, with Herm, Jethou and Lihou, is the legal and administrative centre and is governed by the States of Guernsey. Alderney has its own States and sends two representatives to Guernsey's parliament, and it transferred its taxing rights to Guernsey in 1949. Sark governs itself through the Chief Pleas and sends no representative. Together the islands cover 78 square kilometres.
