How much does outdoor advertising cost in the UK?
Outdoor advertising, also known as out-of-home (OOH) advertising, covers any advertising that reaches people when they are away from home – billboards, bus shelters, roadside digital screens, the Underground, shopping centres and more. One of the most common questions we are asked is a simple one: how much does it actually cost? The honest answer is that it depends, but this guide will give you a clear sense of the numbers.
What affects the cost of outdoor advertising?
Outdoor advertising costs are driven by a handful of factors: the format (a classic paper billboard versus a premium digital screen), the location (a site in central London commands far more than a suburban roadside panel), the length of your campaign, and the time of year. A single roadside 48-sheet billboard might start from a few hundred pounds for a two-week period in a regional location, while a premium digital screen in a high-footfall city centre can run into the thousands.
Digital out-of-home has changed the picture
Digital out-of-home (DOOH) has transformed how outdoor is bought. Rather than booking a single site for weeks at a time, advertisers can now buy screen time in flexible slots, share high-profile locations with other brands, and even trigger ads based on the weather, time of day or live events. Digital now accounts for 67% of all UK OOH revenue, and it is the fastest-growing part of the market.
Is outdoor advertising worth the cost?
It is worth putting that cost in context. UK out-of-home advertising reached a record £1.44 billion in 2025, and for good reason: OOH reaches 98% of the UK population every week. Few other channels offer that kind of broad, unavoidable reach, and because outdoor ads cannot be skipped, blocked or scrolled past, every pound works hard.
