Using plain English

Everything we produce should be written in plain English as described in the GOV.UK plain English guidelines.


  • Write short sentences that are no longer than 20-25 words
  • Include only one main idea in each paragraph
  • Establish a conversational tone by imagining you are speaking to someone
  • Avoid jargon, acronyms and impersonal corporate language
  • Use simple words rather than their longer equivalent: 'If' not 'in the event that'
  • Don't try to include every single detail - only write what readers need to know
  • Write in the active, not passive voice. A hit B is more direct than B was hit by A
  • Ask yourself: Will your audience understand your message or can it be simplified further?
  • Don't be afraid to give clear instructions: 'Please send it to us' is more direct than 'I would be grateful if you would please send it to us'
  • Use bullets and vertical lists to break up text and make information more accessible
  • Use sub-headings to present information in a logical manner
  • When including hyperlinks in electronic documents, don't mention that you are providing a link (ie 'click here). Instead, describe the information you are linking to or just include the link address: more information can be found at
  • Include images to illustrate ideas and make content more reader-friendly
  • Keep your readers in mind. Remember, if you're bored or confused by what you've written, they probably will be too 

Writing for online

People visit our website to get something done or to answer a question. They are impatient and will leave a page quickly if they can't see at a glance what they are looking for or don't understand it.

Don't waste time with long introductions. Be direct and specific in what you need to tell people. Use short paragraphs, clear headlines and sub heads, bulleted lists and words and phrases people are likely to search for.

Put the most important information first and only include information that is essential.

Mobile first

We've designed our website to work on most devices, whatever their size, because an increasing number of people use our site on mobile. Our aim is to make the most important information visible on the first screen.

Jargon and legalese

Simplicity is the key to understanding. Short words in short sentences get your message across more quickly, more easily and in a friendlier way.

Note: Some legal terms have specific legal meanings or implications that may be lost if replaced with plain English alternatives. If you have any questions about the use of legal terms, please contact TfL Legal

Superfluous words and phrases

Another way to save time and avoid confusion is to get rid of unnecessary words. Information can often be made simpler - and less corporate - if words that either add nothing or mean the same thing are replaced with simpler alternatives.

Accessibility for print

  • Type size
    Use a minimum of 12pt for all printed documents. Where possible, use 14pt as this increases the accessibility documents to visually impaired readers
  • Type styles
    Avoid using italics or all capital letters as these make it more difficult for visually impaired readers to recognise word shapes. Underlining should also be avoided to prevent confusion with hyperlinks
  • Reverse type
    If using white or coloured type, make sure the background colour is dark enough to provide good contrast
  • Text alignment
    Text should be left aligned. Avoid justifying text as irregular word spacing can make it more difficult to read. Variable spacing can also make text appear distorted
  • Sentence spacing
    Use a single space at the beginning of sentences as double spaces make text more difficult to read. Variable spacing can also make text appear distorted
  • Line length
    The ideal line length is between 60-70 characters (except when using columns) as very long or very short lines tire the eyes and make reading more difficult
  • Hyphens and split words
    Don't split words over lines because it disrupts the reading flow and can also be confusing
  • Navigational aids
    Leave a space between paragraphs and sections as dividing the text up gives the eye a break and makes reading easier
  • Contrast
    The better the contrast between the background and the text, the more legible the text will be. Black text on a white background provides the best contrast
  • Images
    Don't place text over images as it can be both easy to miss and difficult to read
