Yes. Typeface is a key element of any organisation’s identity so it is important to apply it consistently. Only Frutiger and Arial fonts should be used for NHS communications. No other typefaces should be used even if your NHS communications are aimed at a specific target audience (e.g. children). The only exception is foreign language fonts.
Frutiger has been the NHS font since 1999, and has become recognised as the clean, simple, typeface which people associate with the NHS. The secondary font, Arial, should be used when Frutiger is not available.
