Planning a Bilingual Event in Wales: A Practical Guide for Cardiff Bookers

Events with a public sector, education or Wales-facing audience in Cardiff increasingly need to work properly in both English and Welsh, and doing this well is a genuinely different brief to a standard corporate event, not just a translation layer added at the end. This guide covers what a bilingual event actually requires, from signage and materials to interpretation, and how to brief a Cardiff venue so nothing gets missed. 

A properly bilingual event treats Welsh and English as equal throughout, not English with Welsh added as an afterthought. This means signage, printed materials, the agenda and any on-screen content appearing in both languages, generally with Welsh given at least equal visual prominence, and any welcome or opening remarks delivered in both languages rather than English only with a brief Welsh nod. 

The level of bilingual provision genuinely needed depends on the audience and the organisation behind the event. A Welsh Government-linked or public sector event typically has a higher bar, sometimes a formal Welsh Language Standard to meet, than a private sector event choosing to be bilingual as a matter of good practice. Clarify which applies before you plan, since it changes both the brief and the budget.

For a formal event with mixed-language attendees actively participating in discussion, simultaneous interpretation, delivered live through headsets from an interpreter working in a booth or a quiet adjoining space, is the professional standard. This needs to be planned into the room layout from the start, since it requires either a dedicated interpretation booth or a suitable side room, along with headset distribution and collection at the entrance. 

For a less formal event, consecutive interpretation, where a speaker pauses for a spoken translation, or simply structuring the agenda so key content is delivered separately in each language, can work well and needs far less specialist equipment. Decide which approach the event genuinely needs before booking a venue, since it directly affects room layout and technical requirements. 

Tell the venue explicitly that the event is bilingual and what that means in practice: whether interpretation equipment is needed, whether signage should be produced in both languages by the venue or supplied by you, and whether any venue staff interacting with guests should be able to offer a Welsh greeting or basic service in Welsh. Not every venue will have this as standard, so it is worth asking directly rather than assuming. 

Ask specifically whether the venue has hosted a bilingual event before, since experience here genuinely shows, from how the room is laid out for interpretation equipment to how confidently front of house staff handle a mixed-language guest list. A venue's Member Profile on the Hotal Marketplace is a useful starting point for checking this, and the Network's team can help identify Cardiff Members with a track record here.

Treating Welsh as a translation exercise done at the very end, once English materials are already finalised, rather than planning bilingually from the start. This consistently produces rushed, lower quality Welsh content and a visible gap in polish between the two languages, which stands out precisely because the audience an organisation is trying to serve with a bilingual event is often the audience most likely to notice. 

Build translation and bilingual sign-off into the timeline from the beginning, with the same deadline discipline as the English content, rather than as a final step squeezed in before the event. A good translator or bilingual copywriter needs real time to do the job properly, not a rushed weekend before print.

Is there a legal requirement for events in Wales to be bilingual? 

It depends on the organisation. Public bodies and some organisations delivering services in Wales are subject to the Welsh Language Standards, which set specific requirements for how Welsh is used. Private sector organisations are not legally required to run bilingual events but increasingly choose to, particularly for anything with a public-facing or Wales-wide audience. 

How far ahead should you book Welsh translation and interpretation services? 

For translation of event materials, four to six weeks ahead gives a professional translator realistic time to do the work properly, longer for a lengthy or technical document. For live simultaneous interpretation on the day, book interpreters as early as possible, ideally alongside the venue itself, since qualified Welsh-English interpreters are a genuinely limited pool and get booked up around busy periods.
