Streaming ads in Wales and Scotland: language and access

What to take away

Streaming ads on Welsh and Scottish broadcaster services differ in language context, spot-ad availability and measurement.

The services have different commercial arrangementsSTV sells its airtime and player inventory in-house, while S4C handles spot and sponsorship sales itself.
Glasgow is where Scottish deals are negotiated. Cardiff is Wales's media hub, but S4C is headquartered in Carmarthen, so there is no Cardiff sales desk.
Gaelic spot ads on BBC Alba do not exist. BBC channels carry no spot advertising, so Gaelic money goes to sponsorship and independent production.
Neither market publishes a rate card. Ask for linear and streaming CPMs separately, plus cost per completed view.
Match the creative to the service and audience. Welsh or Gaelic audio or subtitles may suit language-specific stock, but Gaelic creative is optional on STV stock.

Glasgow and Cardiff: where the buying happens

Glasgow is STV's headquarters and the centre for Scottish CTV negotiations. STV holds the Channel 3 licences for central and northern Scotland and sells its own airtime and on-demand impressions. It does not sit inside a national ITV buy.

Cardiff is Wales's media hub, but S4C is headquartered in Carmarthen. That matters if you expect a Cardiff sales desk. Welsh-language enquiries run through S4C's own commercial team.

STV player inventory and Scottish context

STV is the practical entry point for Scottish CTV. Its editorial is largely English language, with Scottish news, sport and current affairs that national channels do not mirror. Scottish relevance, not language, is the filter.

Ask for linear and streaming impressions to be priced separately, because the two are measured differently. Programmatic access exists for some player stock, but the direct conversation sets terms and flighting. To see how broadcaster VOD, AVOD and programmatic deals sit in one plan, read business models explained.

Behind the schedule sit public-service commitments: news, some Gaelic programming and content made in Scotland.

Welsh-language stock on S4C

S4C is the Welsh-language public-service broadcaster, and its language context shapes a CTV buy. Much of its output is commissioned or produced in Welsh, covering drama, sport, children's programming and factual strands. For background, see our guide to language duty.

Spots can run in Welsh or English, but the surrounding editorial is Welsh. English-only creative often reads as out of place, so budget for a Welsh voice-over or Welsh subtitles.

Sponsorship of a Welsh-language strand is often the stronger route. Compliance still applies, because the ASA's advertising codes cover claims, harm, offence and children's scheduling.

BBC Alba and Gaelic spot advertising

BBC Alba is run by the BBC with MG Alba, which is based in Stornoway. It carries Gaelic news, sport, music and children's programming, usually with English subtitles. It sits inside the BBC's no-spot-advertising framework.

That changes the brief: BBC Alba itself is not a spot-ad route. If you are offered Gaelic streaming ads, check whether the stock is BBC Alba itself or Gaelic-language content distributed elsewhere. The buying routes and rules differ.

The practical distinction for an advertiser is the route into each service: S4C sells spots, while BBC Alba carries no spot advertising. To weigh niche supply against mainstream, read whether CTV is a maturing market or a passing fad.

Pricing, measurement and compliance

Neither broadcaster publishes a rate card. Quoted CPMs move with season, volume, targeting and whether linear is included.

Ask for cost per completed view alongside CPM. Small-audience buys can look expensive on reach and reasonable on attention, so the second metric usually decides the campaign.

Measurement runs through BARB and platform reporting. Samples for these services are thin, so expect wider confidence intervals than for peak-time national channels. Most of this supply sits inside broadcaster VOD, which Thinkbox describes as the on-demand home of the main UK broadcasters.

Audiences for language-specific stock are smaller than a UK-wide buy. Ask for current BARB service-level figures rather than accepting adjectives. For the compliance side, our guide to rules and ethics covers claims, consent and scheduling.

A three-step booking sequence

Define the audience: Welsh speakers, Gaelic speakers, or a broader Scottish or Welsh audience.
Decide whether Welsh or Gaelic voice-over or subtitles suit the service and audience; check any seller requirements and use a compliant end tag.
Agree the seller and the measurement before launch, with linear and streaming reported separately.

Common questions

Do I need separate creative for Welsh and Gaelic?

For S4C, plan for Welsh audio or subtitles because the surrounding editorial is Welsh. Gaelic creative is optional on STV stock; for other Gaelic-language supply, check the seller's brief.

Can I buy spot advertising on BBC Alba?

No. BBC services carry no spot advertising, so Gaelic budgets go to sponsorship and independent Gaelic production.

Is STV part of a national ITV buy?

No. STV sells its Scottish airtime and player inventory itself, so it needs its own line in the media plan.

Should Scottish and Welsh stock sit in one campaign?

Keep them as separate lines. They have different sellers, language rules and measurement.
