ABCDEFGHIJKLMNOPQRSTUVWX
1
A*, A*sThe top grade in A levels. Use the symbol * not the word ‘star’. No apostrophe in the plural.
2
A levelNo hyphen. Lower case level.
3
Abbreviations and acronymsThe first time you use an abbreviation or acronym explain it in full on each page unless it’s well known, like UK, DVLA, US, EU, VAT and MP. This includes government departments or schemes. Then refer to it by initials, and use acronym Markdown so the full explanation is available as hover text.

If you think an acronym is well known, please provide evidence that 80% of
the UK population will understand and commonly use it. Evidence can be from
search analytics or testing of a representative sample.

Do not use full stops in abbreviations: BBC, not B.B.C.
4
the academies programmeLower case.
5
academyOnly use upper case when referring to the name of an academy, like
Mossbourne Community Academy. See also 'Titles'
6
academy convertersLower case.
7
academy orderLower case.
8
academy trustLower case.
9

lower case.
10
accountancy service providerUpper case when referring to the business area covered by Money Laundering
Regulations. Do not use the acronym.
11
Accounts OfficeUpper case.
12
Activation PINUpper case. Activation PIN has been changed to Activation Code on outgoing
correspondence from the Government Gateway. Until all hard-coded instances
of Activation PIN have been removed from the Online Services pages, use
‘Activation Code (also known as Activation PIN)’.
13
act, act of ParliamentLower case. Only use upper case when using the full title: Planning and
Compulsory Purchase Act 2004, for example.
14
Active voiceUse the active rather than passive voice. This will help us write concise,
clear content.
15
Addresses in the UKStart each part of the address on a new line. You should:

write the town and postcode on separate lines
not use commas at the end of each line
write the country on the line after the postcode, not before
only include a country if there is a reasonable chance that the user will be writing to the address from a different country
For example:

HM Revenue and Customs - Child Benefit Office
PO Box 1
Newcastle Upon Tyne
NE88 1AA
United Kingdom
16
Addressing the userAddress the user as ‘you’ where possible and avoid using gendered pronouns like ‘he’ and ‘she’. Content on the site often makes a direct appeal to citizens and businesses to get involved or take action: ‘You can contact HMRC by phone and email’ or ‘Pay your car tax’, for example.
17
Adoption RegisterUpper case when referring to the national Adoption Register.

Lower case in subsequent mentions that do not use the full term: the register
18
adviserFor example, special adviser. Not advisor, but advisory is the correct adjective.
19
agesDo not use hyphens in ages unless to avoid confusion, although it’s always best to write in a way that avoids ambiguity. For example, ‘a class of 15 16-year-old students took the A level course’ can be written as ‘15 students aged 16 took the A level course’. Use ‘aged 4 to 16 years’, not ‘4-16 years’.

Avoid using ‘the over 50s’ or ‘under-18s’. Instead, make it clear who’s included: ‘aged 50 years and over’ and ‘aged 17 and under’.
20
agileUpper case when referring to the Agile Manifesto and principles and processes, otherwise use lower case.
21
allow listUse allow list as the noun and allow as the verb. Do not use white list or whitelist.
22
al-Qa’idaNot al-Qaeda or al-Qaida.
23
alternative provisionLower case.
24
American and UK EnglishUse UK English spelling and grammar. For example, use ‘organise’ not ‘organize’, ‘modelling’ not ‘modeling’, and ‘fill in a form’, not ‘fill out a form’.

American proper nouns, like 4th Mechanized Brigade or Pearl Harbor, take American English spelling.
25
AmpersandUse and rather than &, unless it’s a department’s logo image or a company’s name as it appears on the Companies House register.
26
animal healthLower case.
27
antisocialNo hyphen.
28
applied general qualificationsLower case.
29
apprenticeship programmeLower case.
30

31

32
arm’s length bodyApostrophe, no hyphen.
33
assembly ministersLower case.
34
Attendance AllowanceUpper case.
35
Bacs (Bankers Automated Clearing System)Acronym should come first as it’s more widely known than the full name. Please note that the acronym has changed to Bacs.
36
backendUsed in a technical context, not “back-end” or “back end”.
37
Bank detailsWhen adding bank details:

do not use a table - use bullet points and a lead-in line instead
use spaces rather than hyphens in sort codes - 60 70 80 (not 60-70-80)
avoid using spaces in account numbers unless they are very long (like an International Bank Account Number)
For example:

Transfer the fee to the following account within 5 working days of emailing your form:

sort code - 80 26 50
account number - 10014069
account name - The Public Trustee
38
baselineOne word, lower case.
39
Behavioural Insights teamUpper case if it’s a specific, named team. Always lower case for team and generic names like research team, youth offending team.
40
Bereavement PaymentUpper case.
41
Blind Person’s AllowanceUpper case.
42
block listUse block list as the noun and block as the verb. Do not use black list or blacklist.
43
blog postUse 2 words when referring to an article published on a blog. A ‘blog’ is the site on which a blog post is published.
44
boardAlways lower case unless it’s part of a proper title: so upper case for the Judicial Executive Board, but lower case for the DFT’s management board.
45
BracketsUse (round brackets).

Do not use round brackets to refer to something that could either be singular or plural, like ‘Check which document(s) you need to send to DVLA.’

Always use the plural instead, as this will cover each possibility: ‘Check which documents you need to send to DVLA.’

Use [square brackets] for explanatory notes in reported speech or for placeholder text:

“Thank you [Foreign Minister] Mr Smith.”

“Witnessed by [signature of witness].”
46
BrexitYou can use the term ‘Brexit’ to provide historical context, but it’s better to use specific dates where possible. For example, use:

‘31 December 2020’ rather than ‘Brexit’ or ‘when the UK left the EU’
‘before 31 December 2020’ rather than ‘during the transition period’
‘after 1 January 2021’ rather than ‘after the transition period’
47
BTEC National DiplomaUpper case.
48
Bullet points and stepsYou can use bullets to make text easier to read. Make sure that:

you always use a lead-in line
you use more than one bullet
the bullets make sense running on from the lead-in line
you use lower case at the start of the bullet
you do not use more than one sentence per bullet - use commas or dashes to expand on an item
you do not put ‘or’ or ‘and’ after the bullets
you do not make the whole bullet a link if it’s a long phrase
you do not put a semicolon at the end of a bullet
there is no full stop after the last bullet
Bullets should normally form a complete sentence following from the lead text. But it’s sometimes necessary to add a short phrase to clarify whether all or some of the points apply. For example, ‘You can only register a pension scheme that is one of the following:’

The number and type of examples in a list may lead the user to believe the list is exhaustive. This can be dealt with by:

checking if there are other conditions (or if the list is actually complete)
listing the conditions which apply to the most users and removing the rest
consider broader terms in the list which capture more scenarios (and could make the list exhaustive)
creating a journey to specialist content to cover the remaining conditions
