About the Welsh language
Welsh is a Celtic language of the Brittonic branch, native to Wales and spoken by communities in England and — interestingly enough — Patagonia, Argentina.
According to the 2021 Census, 17.8% of the Welsh population could speak Welsh, while more recent surveys suggest as many as 828,600 speakers (26.9%) in 2025. Welsh is also seeing year-on-year growth in schools, with the Government aiming for one million Welsh speakers by 2050.
The Welsh Language Act 1993 first established the principle of equality between Welsh and English in public services, while the Welsh Language (Wales) Measure 2011 gave Welsh official status, making it one of the two de jure official languages of the Senedd (Welsh Parliament).
Welsh is renowned for its rich literary tradition and distinct phonology. Its preservation and growth make professional expertise essential for accurate, culturally respectful translation and localisation.
The importance of Welsh for business and public services
Bilingual communication is not only a matter of inclusivity in Wales; in many cases, it is a legal requirement.
From government consultations to corporate branding, delivering content in both Welsh and English builds trust, accessibility and compliance.
For businesses, Welsh translation demonstrates commitment to communities, strengthens brand reputation, and supports expansion within Welsh markets. For public services, it is central to meeting statutory duties under the Welsh Language Act and the standards set by the Welsh Language Commissioner.
With our roots in Swansea and with nearly two decades of expertise, Wolfestone is uniquely positioned to deliver Welsh language services that meet both cultural expectations and legal obligations.
