Always use the British spelling of words such as "colour", "travelling", "centre", and "analogue". This is a good guide to the ways British and American spellings differ. Note that BuzzFeed UK (like most UK publications) spells words like "apologise" and "realise" with -ise, not -ize.

Never use full stops ("periods" in American English) in acronyms, so write UK, US, UN, LA etc. Otherwise follow standard BuzzFeed style by putting all acronyms in caps unless they are more than five letters long, so write AIDS and BBC but Unesco and Unicef. Exceptions include TARDIS, TfL, and many government departments – see list of political terms for more.
Acronyms that will be familiar to an intelligent British audience do not need to be written out in full, especially if they're better known as acronyms. These include AIDS, BBC, CEO, CPR, HBO, HIV, ITV, MTV, PETA, PMS, TED, and UKIP. Use your judgment.
Nouns such as collective, committee, family, gang, generation, government, jury, and team can be singular ("the government is launching a new initiative") or plural ("the government are squabbling") depending on whether they are thought of as a single entity or a group of individuals. Follow common sense and be consistent.
Nouns such as couple, pair, and trio can also be singular or plural, but are usually plural when referring to people, so write: "The charming couple were sharing an ice cream."
In general, police forces are plural and "police" is capped down: The Metropolitan police are investigating..., Yorkshire police are investigating..., etc. But they are singular and capped up when the force is being referred to as a single service: The Met is..., the Metropolitan Police Service is..., the British Transport Police is..., Police Scotland is, Norfolk Constabulary is... etc.
Do not use full stops (periods) in contracted words such as Mr (Mister), Dr (Doctor), Jr (Junior), St (Saint), and vs (versus).
Initial-cap court names when the institution is one of a kind, e.g. the Supreme Court, the High Court, the Court of Appeal, the European Court of Justice.
When the court type is a local or generic one, initial-cap place names only: Derby magistrates' court, Cambridge crown court, youth court, family court.
Always use the apostrophe in magistrates' court.
For dashes, always use an en dash (–) rather than the em dash (—) preferred in the US. Hyphens (-) remain hyphens.
Do not hyphenate "then" and "now" nouns, so write then prime minister John Major, now 23-year-old Ebeneezer Goode etc.
Dates and times
Write dates in the order of day/month/year without commas, like this: 9 December 2014. Don't abbreviate months (except, for example, for space reasons in a graphic, in which case you can write 5 Nov 2017 with no full stop).
Write 9am and 10:35pm instead of 9 a.m. and 10:35 p.m.
Cap specific defined regions such as the North East, the South East, East Anglia etc, and also cap conceptual regions such as the North, the South, the East End, and the West Country.
But decap non-defined regions and directionals: east London, north Glasgow, northeast Wales, the southwest of Scotland, eastern Europe. Also decap northerner and southerner.
In UK style, refer to "disabled people" rather than "people with disabilities". This is in line with the social model of disability, which argues that people have impairments, not disabilities, and are disabled as a result of barriers put in place by society. Never use the term “the disabled”.
Avoid the US habit of dropping prepositions such as "on" and using "likely" to mean "probably". For example, "the meeting will likely happen Wednesday", which is perfectly acceptable in US English, is ungrammatical in British English and should be recast as "the meeting will probably happen on Wednesday" or "the meeting is likely to happen on Wednesday".
Another US habit to avoid is using "with" to form phrases such as "speak with", "meet with", "talk with" etc. Instead, say "speak to", "meet", "talk to".
Also: Don't say "protest a decision" – say "protest against a decision"; and don't say "different than" – say "different to" or "different from".
Job titles and honorifics
Do not cap up job titles. So write prime minister David Cameron, not Prime Minister David Cameron, and editor-in-chief Janine Gibson, not Editor-in-Chief Janine Gibson.
Military and police ranks are treated as honorifics, so cap when used before a name at first mention: Colonel James Mustard (thereafter Mustard or the colonel), Detective Chief Inspector Gene Hunt or DCI Gene Hunt (thereafter Hunt or the detective chief inspector) etc.
Peers should be referred to by the name they're commonly known as at first mention (e.g. Shami Chakrabarti), by their title and surname at second mention (Baroness Chakrabarti), and from then on by their surname (Chakrabarti). If they're commonly known by their title (e.g. Lord Leveson), use title and surname at first mention and then subsequently just their surname (Leveson).
The title Dr should only be used for doctors of medicine or science.
Stick to US style for feet, inches, Fahrenheit etc.
For metric measurements, typically abbreviate like this: 9g, 9kg, 9km, 9cm, 9mm, 9ml etc. However, spell out litres and metres, so write 9 metres, 9 litres etc.
Write Celsius like this: 38°C.
99p, £10, £5 million, fiver, five quid.
Use € sign for euros rather than spelling out.
Northern Ireland, along with the three countries that make up the island of Great Britain, is part of the UK. It can be described as a country or a region, but do not call it a province. Also: Do not use Ulster as a synonym for Northern Ireland (part of Ulster is in the Irish Republic). Residents of Northern Ireland can be described as Irish, Northern Irish, or British, depending on their personal preference.
unionist = in favour of political union with Great Britain
loyalist = not synonymous with unionist, although also in favour of political union with Great Britain. Usually implies support for a level of paramilitary action towards that aim
nationalist = belief in the unity of the people of Ireland. Usually indicates support for a united Ireland
republican = usually indicates support for the right to use violence to achieve a united Ireland
See the Northern Ireland section below for a list of related political terms.

When fragmentary quotations are used, punctuation goes outside the quote marks, "like this". If a whole sentence is included in the quote, "include punctuation. Like this."
Never include sentence punctuation in song titles unless it is part of the song, so write "(I Can't Get No) Satisfaction", not "(I Can't Get No) Satisfaction."
Always use double quotes ("like these") in headlines/deks and copy. Single quotes ('like these') are used only inside reported speech.
When using an en dash for attribution, style like this: “Quote.” – Person Who Said Quote
In general, use metric measurements rather than imperial, and abbreviate them like this: 5g, 5kg, 5ml etc. Exception: Write out litres, like this: 5 litres, 1 litre etc.
For other measurements, keep a space after the numeral. Spell out teaspoon and tablespoon measurements like this: 5 teaspoons milk, 6 tablespoons sugar. Do not use cup measurements. Also note that certain everyday imperial terms such as pint are fine in the right context, such as if the recipe includes a pint of beer.
When describing cooking temperatures, always lead with Celsius.
For info on international differences in the names of foods, this is useful.
Titles such as the Duke and Duchess of Cambridge or the Prince of Wales are capped at first mention, then subsequently decapped to the duke and the duchess or the prince. The exception is the Queen, whose role is always capped.
The Duke of Cambridge is also called Prince William, and Catherine, Duchess of Cambridge, can also be referred to as Kate in headlines, deks, and lighter posts. She should never be called Princess Kate or Kate Middleton (her former surname), however.
Do not cap "royal" in phrases like the royal baby or the royal family.
The word "cunt" is far less offensive in British English than US English, and is non-gender-specific as a swearword. It does not need censoring in posts unless quoted in a headline, in which case write "c*nt". For more information on British swearing, see the BuzzFeed guide to UK swearword usage.
