A DOOH platform for the UK, book London by the hour.

What a UK DOOH platform is

The important word is self-serve. Most UK out-of-home is still bought through a media agency or a demand-side platform, which means a seat, a briefing cycle and a modelled CPM package. On Blindspot you do the buying: you draw a radius around a London neighbourhood, filter to the format you want, watch the per-play price and live availability update as you go, and confirm. The same account books one screen for a weekend or a multi-city UK flight for a month. It is the same platform that runs digital billboards across Europe and, in total, more than 3 million screens across 50 or more countries, so a UK campaign sits alongside the rest of a wider plan on one login and one invoice.

Because you buy per play rather than per thousand modelled impressions, the numbers reconcile the way a spreadsheet does. You pay for the appearances that ran, each logged with a time and a place, not for an audience forecast you cannot audit. That single change is what makes a few hundred pounds a real UK campaign instead of a rounding error against a rate card.

That is the efficiency point: a single-neighbourhood London budget and a national UK flight both buy real exposure by the hour rather than filler, so the plan works as hard at a few hundred pounds as it does at a few hundred thousand.

Book the UK, city by city

London is the deepest UK market on Blindspot and the place most campaigns start. Prices are per play in USD, shown on each screen: a London billboard runs a median of about $0.17 a play and an urban panel about $0.11, with transit peaks up to roughly 3.8 times off-peak, from live inventory in Q3 2026. The other major cities are bookable from the same map.

Per-play figures are screens-weighted medians from live Blindspot inventory, Q3 2026, rounded to the cent, and London is the market with published per-play data here. Availability and prices change, and every screen shows its own price before you book. For the full picture of what plays cost, see the billboard cost guide and the European per-play cost guide.

The Trade Desk vs a self-serve platform

Search for a DOOH platform for the UK and you will often land on The Trade Desk. That is fair: it is a large, capable demand-side platform, and plenty of UK out-of-home moves through it. But it answers a different question than most people asking one. A DSP like The Trade Desk needs a seat, and it is typically operated by a media agency or a trading desk rather than the advertiser directly. It buys programmatic supply on CPM, the cost per thousand modelled impressions, and it is designed for planners buying audience in bulk across many channels at once.

Vistar works on the same wholesale side of the market, as a supply and demand platform for programmatic DOOH. None of that is a criticism. If you have an agency and a trading desk and you want UK screens to sit inside a wider programmatic plan, those routes do the job well, and you should use them.

Blindspot is the other shape. It is direct and self-serve: no seat to acquire, no agency required, and no trading desk between you and the screen. You buy per play, not on CPM, and the price is shown on every screen card before you book, so there is no quote to wait for and nothing modelled to reconcile after the fact. That is the honest split: a DSP is the right tool for an agency buying programmatically at volume, and a self-serve platform is the right tool for a brand, a founder or a small team that wants to see the price, pick the screens, set the hours and go live without a seat. If you want to compare the field, the best DOOH platforms guide lays the options out side by side, and the self-serve billboard platform page explains how the direct model works end to end.

London, proven on real campaigns

London is not a theoretical market on Blindspot. On a worldwide tourism campaign for the government of Maharashtra, London was the single largest market, delivering 380,215 verified plays on its own. Placements ran on flagship inventory including the Hammersmith Towers and the London Underground, the same kind of street and transit screens any UK advertiser can book from the map today.

The campaign as a whole delivered 2,146,892 plays, which was 87% more than planned, and it did that by concentrating delivery into the hours that carried the audience rather than paying for empty ones. That is the same hourly scheduling every UK campaign gets: the reason London worked so hard on that plan is the reason a smaller London buy works hard for a small budget. You can read the full Visit Maharashtra case study for the market-by-market breakdown, or start with London yourself and see the per-play prices on real screens.

UK airports on one platform

Airport screens are the premium end of UK DOOH, and they book from the same account as everything else. The main UK gateways carry dense digital inventory with long dwell times: Heathrow and Gatwick serving the London catchment and international arrivals, Manchester covering the north, and Edinburgh anchoring Scotland. These are captive, high-intent environments, priced per play like every other screen, so you see the cost before you commit and schedule the flight windows that match your audience.

Airport plays sit at the higher end per play because the placement is premium and the dwell is long, so the same budget buys fewer appearances than a street panel would. That is a reason to schedule tightly, not a reason to avoid them. Browse the full picture on the airport advertising page, then mix airport screens with London street and transit inventory in one plan. If you would rather not build it by hand, Blinky can draft a UK plan from a one-line brief, or you can request a media plan and have one put together for you.
