TV Advertising costs in United Kingdom

UK television has no price list. ITV, Sky Media and Channel 4 publish no public rate card, and every widely circulated “cost of a TV ad” table traces back to an agency estimate rather than to a broadcaster. That absence is not a gap in our data. It is how the market works, and it is the first thing a buyer needs to understand.

Airtime is traded on cost per thousand impacts. Thinkbox, the marketing body for UK commercial broadcasters, defines CPT as the cost of buying 1,000 impacts and notes that CPTs are “usually represented in the form of a percentage discount off the station average price (SAP)”. SAP itself is calculated by dividing total revenue by total viewing, monthly, for each audience a broadcaster trades on. Price is therefore an output of supply and demand rather than an input a seller sets.

What that means in practice is that the audience you buy, not the channel or the show, sets your cost. Thinkbox puts an All Adults buy at roughly 6 pounds per thousand and a 16-34 buy at roughly 30 pounds per thousand: a fivefold spread on identical airtime, because scarce audiences cost more to accumulate. Four further variables move the number. Length is scaled from a 30 second standard unit at a factor of 1.00, with 60 seconds at 2.00 and shorter lengths carrying a premium. Season matters, with Thinkbox naming January the cheapest month, on low advertiser spend against high post-Christmas viewing, and September to November the most expensive as pre-Christmas demand outpaces the audience it buys. Region matters, with London the most expensive market on low supply and high demand. Daypart matters, with peak running 1730 to 2259 and attracting the strongest competition.

Then there is the deal itself. Most UK airtime is bought under annual agreements in which an advertiser commits a share of its television budget in return for a fixed position against SAP. Thinkbox gives the worked example of a brand committing 30 percent of annual spend for a price 10 percent below SAP. Two advertisers buying the same break in the same week can pay materially different prices on the strength of that commitment alone.

The practical floor is lower than the market’s reputation suggests. Thinkbox reports that in 2025, 598 UK advertisers spent under 50,000 pounds on television, over 400 spent under 25,000 pounds and more than 200 spent under 10,000 pounds, while 984 advertisers appeared on TV for the first time.

We publish one number on this page because one number is all that is currently sourceable to a primary publisher. Station average prices themselves, daypart and regional multipliers, broadcaster video-on-demand CPMs, and addressable TV minimum spends are not published by any UK broadcaster or industry body we can cite, so they are absent here rather than estimated. Our methodology sets out the sourcing rules; broader UK market context sits in the United Kingdom advertising guide.
