Welsh Language in Construction: When You Must Provide Bilingual Documents

SiteKiln gives you plain-English information, not legal advice. If you need specific guidance on Welsh language compliance for a public sector contract, contact the client's Welsh language officer or the Welsh Language Commissioner.

‍‌‌​‌‌‌‌‌‌​‌​​‌‌‌​‌‌‌​​​​​​‌​‌​‌‍# Welsh Language on Construction Sites, What You Actually Need to Know

You only really need to think about Welsh language rules if you're working on public-facing jobs for public bodies in Wales. Private domestic work isn't suddenly bilingual.

1. The law, who it actually applies to

The Welsh Language (Wales) Measure 2011 makes Welsh an official language in Wales, establishes the Welsh Language Commissioner, and introduces Welsh Language Standards to ensure Welsh isn't treated less favourably than English.

Those standards mainly apply to:

• Public bodies · councils, NHS trusts, NRW, colleges, universities, Welsh Government and its agencies
• Some private and third-sector organisations when delivering public services under contract to those public bodies

Key point for tradespeople:

Standards are imposed on named organisations, not on every plumber or bricklayer working in Wales. Private domestic clients, small private firms, and private developers are not directly bound by Welsh Language Standards.

The duties sit with the public body. If requirements flow down to you, it's because the public body has included them in their contract or specification, not because you have a standalone legal duty.

2. When construction work is affected

You'll feel the Welsh language rules when you work on public-facing projects for bodies that have Welsh Language Standards or a Welsh Language Scheme.

Jobs where you'll see Welsh language requirements

• Works on council offices, schools, hospitals, universities, NRW sites, Welsh Government buildings
• Public realm work · streetscapes, parks, bus stations, train stations, public car parks, leisure centres
• Social housing projects for housing associations or councils
• Any project where your client is a public body or a main contractor delivering a public service contract with Welsh language requirements written into the specification

On those jobs, the client (council, NHS, NRW, main contractor) must meet their Welsh Language Standards. They'll pass relevant requirements down to you through the contract or specification.

Jobs where you won't

• Private domestic work · extensions, kitchens, bathrooms, driveways, rewires, boiler installations for homeowners
• Private developer projects · new housing estates, private commercial buildings
• Landlord work · unless the landlord is a housing association or council with Welsh Language Standards

There is no general legal duty on private individuals, private developers, or domestic households to provide bilingual signage or services in Wales.

3. What's typically required on public sector jobs

If you're on a public sector project in Wales, you may see requirements like:

Bilingual site signage

• "Site office / Swyddfa'r safle", "No entry / Dim mynediad", "Visitors report to reception / Ymwelwyr i adrodd i'r dderbynfa"
• Standard construction signs (danger, no access, PPE required) in Welsh and English

Welsh-first or equal prominence

• Many Welsh Language Standards require Welsh to be no less prominent than English on signs and notices
• Some public bodies choose Welsh first (Welsh on top, English below) · this is a policy choice, not always a legal requirement, but common on council and NHS sites

Bilingual safety notices in public areas

• Where the public can see the signs · site hoardings, perimeter notices, pedestrian diversion signs · they should be bilingual
• Internal site notices (toolbox talk boards, RAMS on the cabin wall) aimed at workers only are not usually required to be bilingual

Bilingual project hoardings

• Public information boards explaining the scheme, contact numbers, complaint procedures, community liaison details · all bilingual
• These are usually provided by the main contractor or client, not the subbie

Bilingual correspondence and tender documents

• Public bodies often have to offer documents and communication in Welsh and English
• On site, this typically means the client provides bilingual templates · you don't have to translate your own quotes or invoices

The specific requirements live in each client's Welsh Language Standards compliance notice or Welsh Language Scheme. They're the ones who must comply. They'll tell you what they expect from you.

4. How it affects tendering for public sector work

If you're bidding for public sector work in Wales, either directly or as a subcontractor to a main contractor, you may see:

Tender questions

• "How will you provide Welsh language services or comply with the client's Welsh Language Standards?"
• "Can you provide bilingual signage for public-facing areas?"
• "Do you have any Welsh-speaking staff?"

Typical requirements in the specification

• Provide bilingual site signage and public-facing notices (often using the client's standard wording and templates)
• On larger projects: have at least some Welsh-speaking front-of-house staff (reception, information desk, community liaison)
• Handle complaints and correspondence in Welsh where requested · often managed through the main contractor, not you directly

The Welsh Language Commissioner's position

The Commissioner's advice to public bodies is clear:

• They must build Welsh language requirements into contracts where services are delivered to the public
• They must not avoid Welsh language requirements just because it might favour bidders with more Welsh-language capability
• Using Welsh is recognised as a legitimate public interest in procurement

What this means for you

• On big public jobs, being able to deliver bilingual signage and documents is standard. Budget for it.
• Being able to name a Welsh-speaking supervisor or office contact is a bonus in tender scoring · not a strict requirement for most trades, but it helps
• If you can't offer Welsh-language capability, be honest in the tender and show you'll work with the client's Welsh language team or use their templates. That's usually enough.

5. Do most tradespeople need to worry about this?

Honest answer:

If you mainly do private domestic work · kitchens, bathrooms, extensions, driveways, landlord repairs · you probably won't encounter formal Welsh language requirements at all. Nobody is going to ask you to put bilingual signs on a bathroom refit in Swansea.

If you work on public sector jobs in Wales, councils, NHS, universities, NRW, major transport projects, you should expect bilingual signage and public-facing materials as standard. It's part of the job, like wearing a hard hat.

Practical middle ground

• Have a signage supplier who can produce Welsh/English boards using the client's standard wording. Most signage companies in Wales do this routinely.
• Be ready for tender questions about respecting the Welsh language and following the client's standards · even if your entire gang is English-speaking. The question is about willingness and process, not fluency.
• You don't need to translate your van livery, your quotes, or your invoices unless you choose to. The legal duties sit with public bodies, not with every sole trader.
• If you do add Welsh to your van or website voluntarily, many Welsh clients and communities notice and appreciate it · it's a goodwill gesture that can help with local reputation.

6. Quick reference: what's bilingual and what isn't

What to do next

1. If you're bidding for public sector work in Wales: check the tender documents for Welsh language requirements · they'll be in the specification
2. If you're already on a public sector site: ask the main contractor or client's project manager what their Welsh language requirements are and whether bilingual signage templates are provided
3. If you're doing private domestic work: this guide doesn't apply to you. Carry on.
4. If you want to add Welsh to your business voluntarily: a bilingual website, van livery, or social media presence can help with local reputation in Welsh-speaking areas · but it's your choice, not a duty
