The minimum budget for a startup to test TV advertising in the UK

UK television has more small doors than its reputation suggests. Sky's AdSmart site advertises TV from as little as £3,000, and Sky says you pay for an ad only once at least 75% of it has been viewed. Universal Ads, Comcast's self-serve platform, launched in the UK on 23 June 2026 with Channel 4, ITV and Sky, and its UK site advertises a £0 minimum spend. STV's self-service calculator books Scottish regions in runs of one week, ten days or two weeks and works out the price as you fill it in, and ITV says half its advertisers are small businesses running regional ads.

Thinkbox, the trade body for commercial TV, counts 598 advertisers that spent less than £50,000 on TV in 2025, more than 200 of them under £10,000, and 984 advertisers new to TV that year. Its job is to promote TV, and the counts are still counts: small budgets on television are ordinary.

Linear airtime is priced another way. Thinkbox puts the average cost of reaching 1,000 adults with a 30-second ad at £7.23, or 0.72p a person, on 2025 data. That figure is per thousand impacts, a measure of linear viewing, and Thinkbox notes that broadcaster streaming is traded on impressions instead, so it does not compare directly with a streaming CPM.

Three costs sit outside the airtime, and the first is mostly time.

The homepage planner splits a monthly budget with the product's own goal weights and drops any line that cannot clear its plan floor. Television's floor is £1,000 a line. The table runs that arithmetic at the planner's own budget stops, over a four-week flight, for each goal.

At £2,000 television drops on every goal. That budget is this site's entry point because it funds two or three channels properly, so at that level the stronger plan concentrates on two or three channels and adds television later. At £12,500 all seven lines fund on awareness and consideration plans, while a performance plan, which weights search and social far more heavily, still drops television.

If television is the question, test television on its own. A plan with only a television line puts the whole budget there, and AdBuyMCP's Sky AdSmart workflow checks Sky's £3,000 minimum before it generates a booking document. On £3,000 of media the fee is £300 at the standard 10% rate; the 5% tier, with its £749 monthly fee, starts above £25,000 of trailing 30-day spend.

Choose the region before the budget. An addressable burst concentrated in a few postcode districts or one broadcast region gives each household there more chances to see the ad than the same money spread nationally, and it leaves the rest of the country as a comparison.

Then write down what the test is for. A first burst can show that the ad clears, runs and reads well, and whether response on your own site moves in the region you bought compared with the regions you did not. A claim that television caused sales needs a powered geo test, and whether one is possible depends on the conversions in the test region, which the small-budget power guide lets you check before you spend.

AdBuyMCP compiles your audience into Sky AdSmart's household attributes, scores the translation 55 out of 100 at household level, generates the booking document, drives the Clearcast step and holds the booking's state. A named person at the sales house makes the booking and reports the delivery. AdBuyMCP does not buy ITV, Sky or Channel 4 inventory directly, and its Universal Ads connector is a stub that makes no vendor call.
