Flags are part of everyday life in the United Kingdom: the Union Flag over town halls and government buildings, the Cross of St George, the Saltire and the Red Dragon on national days, club and company flags on flagpoles in gardens, schools and business parks. In its guidance on flying flags, the government describes flags as “a very British way of expressing joy and pride”. Yet the rules behind them are spread across royal command, government guidance, planning law and the practices of four nations. This section brings together what applies to flag flying and flagpoles in the UK, with sources from UK legislation, the UK and devolved governments and the Flag Institute.

The essentials

  • Flag days: The Department for Culture, Media and Sport lists designated days on which the Union Flag must be flown on UK government buildings, from Commonwealth Day and Coronation Day to Remembrance Day. The dates are in the guide to flag days.
  • Who may fly flags: No permission is needed to fly the national flags. The details are in the guide to flag flying rules.
  • Half-mast: Half-mast means two-thirds of the way up the flagpole, according to the Scottish Government and the Flag Institute. More in the guide to half-mast.
  • Size: As a guide, the Flag Institute gives a flag length of no more than one third of the height of a ground-level pole. The flag size calculator works it out.
  • Buying: What affects the price is explained in the guides to buying a flagpole and buying a flag.
  • Planning: According to the Planning Portal, one garden flagpole up to 4.6 metres high does not need planning permission. More in the guide to installing a flagpole.

Law, guidance and responsible bodies

The UK has no single flag law. According to the Flag Institute, the Union Flag is the national flag by long-established custom and practice rather than by statute, and an attempt to give it a basis in law, the Union Flag Bill of 2008, did not progress beyond its first reading. The College of Arms, the Crown body responsible for heraldry in England, Wales and Northern Ireland, publishes approved designs of the Union Flag.

Flag flying on government buildings is set by different bodies in each part of the UK:

AreaRules for government buildings
UK governmentGuidance from the Department for Culture, Media and Sport, with designated days by command of the King
ScotlandFlag flying guidance from the Scottish Government, issued each year
WalesThe UK designated days apply to UK government buildings, including St David’s Day on 1 March
Northern IrelandThe Flags Regulations (Northern Ireland) 2000, which are legislation rather than guidance

For private individuals, companies and clubs there is no duty to fly a flag and there are no fixed times. The practical rules come from elsewhere: in England and Wales, flags are treated as advertisements under the planning regime, while in Scotland, according to the UK government, flag flying is outside the advertisement control regime. The Flag Institute, a UK flag charity, publishes a detailed guide to UK flag protocol together with the UK Parliamentary Flags and Heraldry Committee.

There are no national rules on what a flagpole must look like. Whether planning permission is needed depends on the pole’s height and location: according to the Planning Portal, one flagpole up to 4.6 metres in a garden does not need an application, while a taller pole or one at a listed building or in a conservation area does. Aluminium and glass fibre flagpoles are common in gardens; businesses, schools and public buildings often have taller poles, sometimes in groups for several flags. More in the guides to types of flagpoles and flagpole heights.

Frequently asked questions

Can anyone fly the Union Flag in the UK?

Yes. According to the Flag Institute’s UK flag protocol, no permission is needed to fly the national flags, and flags may be flown on every day of the year. In England, the plain English guide from the government confirms that any country’s national flag can be flown without advertisement consent.

Which days are official flag days in the UK?

The Department for Culture, Media and Sport publishes designated days on which the Union Flag must be flown on UK government buildings, such as Commonwealth Day, Coronation Day, the King’s Official Birthday, Remembrance Day and the national saints’ days in England, Scotland, Wales and Northern Ireland. Government buildings are also encouraged to fly the Union Flag all year round.

Do I need planning permission for a flagpole?

According to the Planning Portal, one flagpole up to 4.6 metres high can be put up in a garden without planning permission. A taller pole, or one at a listed building or in a conservation area, needs consent. The rules differ between England, Wales, Scotland and Northern Ireland, and the local council can confirm what applies to a specific site.

Is there a law that defines the Union Flag?

No. According to the Flag Institute there is no Flag Act in UK law, and the Union Flag is the national flag by long-established custom and practice rather than by statute. The College of Arms publishes approved designs of the Union Flag.

How is a flag flown at half-mast in the UK?

The Scottish Government and the Flag Institute describe half-mast as two-thirds of the way up the flagpole. According to the Flag Institute, the flag is first raised to the top, then lowered to the half-mast position, and there is at least the height of the flag between the top of the flag and the top of the pole.
