Outdoor advertising in the UK offers two broad categories of billboard: static and mobile. Static billboards are the traditional roadside poster sites, digital screens at roadsides, and large-format displays you see in fixed positions across cities and motorways. Mobile billboards, also known as digital advans, are purpose-built vehicles carrying large LED screens that travel through your target areas on bespoke routes.
Both formats deliver high-impact, unmissable advertising. But they work in very different ways, cost different amounts, and suit different types of campaign. If you are planning an outdoor advertising campaign and trying to decide between mobile and static, this guide lays out the facts so you can choose with confidence.
For background on outdoor advertising in general, see our complete guide to OOH advertising.
What is a Static Billboard?
A static billboard is a fixed advertising display in a permanent location. The most common formats in the UK include 6-sheets (at bus stops and shopping centres), 48-sheets (the standard roadside billboard at roughly 3 metres by 6 metres), 96-sheets (double the size, typically on major roads and motorways), and large-format digital screens in city centres.
Static billboards are booked for a set period, usually a minimum of two weeks. Traditional paper billboards display a single printed poster for the entire booking. Digital billboards rotate multiple advertisers on a single screen, with each ad appearing for around 10 seconds before cycling to the next.
The strength of a static billboard is sustained presence. If you book a 48-sheet on a busy commuter route, every person who drives or walks past that spot will see your ad, multiple times a day, every day, for the duration of your campaign. That repetition builds brand recognition. For a full breakdown of what static billboards cost, read our billboard advertising cost guide.
What is a Mobile Billboard?
A mobile billboard is an advertising display mounted on a vehicle that drives through target areas. The modern version of this is a digital advan: a truck or large van fitted with high-brightness LED screens that display full motion video, animations, and static images while travelling through streets, past events, and through busy commercial areas.
Mobile billboards are hired on a daily basis. You choose the routes, the timing, and the content. The vehicle drives a planned route for typically 8 hours per day, and every metre of the journey is GPS tracked. Content can be changed remotely at any point during the campaign.
The key advantage of a mobile billboard is flexibility. Instead of waiting for your audience to pass a fixed point, you take your advertising directly to them, wherever they are. You can cover multiple areas in a single day, target specific locations like competitor stores or event venues, and adjust your route based on real-time conditions.

Head-to-Head Comparison
Here is how mobile billboards and static billboards compare across the factors that matter most when planning a campaign:
| Factor | Mobile Billboard | Static Billboard |
|---|---|---|
| Coverage | Multiple areas per day | One fixed location |
| Content type | Full motion video, 3D, static | Static print or shared digital rotation |
| Minimum booking | 1 day | 2 weeks |
| Starting cost | From £750/day | From £425/2 weeks |
| Targeting | Bespoke routes, GPS tracked | Fixed location only |
| Content updates | Instant, remote | Requires re-print or shared slot |
| Proof of delivery | GPS verified route reports | Site photograph only |
| Night visibility | Self-illuminated LED | Varies (some lit, many unlit) |
| Best for | Launches, events, tactical | Long-term awareness |
Cost Comparison: Mobile vs Static
Cost is usually the first question, and the answer depends on how you measure it. On a pure cost-per-day basis, static billboards are cheaper. A standard 48-sheet roadside billboard costs between £425 and £750 for a two-week booking, which works out to roughly £30 to £55 per day. A digital advan starts from £750 per day.
However, that comparison is misleading if you do not account for what each format delivers. A static billboard sits in one location and relies on passing traffic. A mobile billboard travels through multiple high-footfall areas, delivering your message to different audiences throughout the day. It also shows full motion video on a dedicated screen, not a 10-second slot shared with five other advertisers.
| Metric | Mobile Billboard (Digital AdVan) | Static Billboard (48-sheet) |
|---|---|---|
| Cost per day | £750 – £999 | £30 – £55 |
| Impressions per day | 50,000 – 100,000 | 15,000 – 40,000 |
| Cost per 1,000 impressions | £7.50 – £20 | £0.75 – £3.50 |
| Share of voice | 100% (your ad only) | 100% (paper) or 16% (digital rotation) |
| Video capability | Full motion, 3D anamorphic | Static image only (paper) or short loop (digital) |
| Locations covered | 10+ areas per day | 1 fixed site |
Static billboards win on raw cost per thousand impressions. Mobile billboards win on quality of impression, targeting precision, and flexibility. The right choice depends on whether you need broad, low-cost reach over weeks or high-impact, targeted exposure over days.

This is where the two formats diverge most dramatically. A static billboard gives you zero flexibility once it is booked. Your poster goes up at a fixed site, stays there for the duration, and you hope the right people walk or drive past. You cannot move it, change the creative (unless it is digital), or adjust the timing.
A mobile billboard is the opposite. Every aspect of the campaign can be adjusted, even mid-flight. You can change the route each day to cover different neighbourhoods. You can update creative content remotely within minutes. You can target competitor locations, events, or high-footfall areas at specific times. If it starts raining and foot traffic shifts indoors, you can reroute the advan to covered areas with higher pedestrian density.
This flexibility makes mobile billboards particularly powerful for:
- Competitor conquesting:Drive your advan directly past competitor stores, showrooms, or offices with your offer on screen. A car dealership advertising outside a rival's showroom. A fast food brand driving past a competitor's high street location. Perfectly legal, devastatingly effective.
- Event targeting:Position your mobile billboard on approach and exit routes to stadiums, concert venues, conferences, and festivals. Capture tens of thousands of attendees in a single session.
- Geo-targeted launches:Cover specific postcodes, boroughs, or neighbourhoods relevant to your product. A fitness brand could target gym-dense areas. A property developer could target affluent residential streets near their new development.
- Multi-city campaigns:A single mobile billboard can cover London on Monday, Birmingham on Tuesday, and Manchester on Wednesday. Try doing that with a static billboard.
Reach and Impressions
Static billboards excel at building frequency. If your billboard is on a commuter route, the same people will see it every morning and evening for the duration of your campaign. That repetition is powerful for brand recall. A well-placed 48-sheet billboard can generate 15,000 to 40,000 impressions per day depending on location, traffic, and time of year.
Mobile billboards generate a different kind of reach. Instead of the same audience seeing your ad repeatedly, you reach new audiences across different areas. A digital advan on a well-planned route through Central London can generate 80,000 to 100,000 impressions in a single day. Over a five-day campaign covering different areas each day, that is potentially 400,000 to 500,000 unique impressions.
The quality of those impressions matters too. A mobile billboard is unusual and eye-catching by nature. A 35-square-metre LED screen driving down a high street is impossible to ignore. People stop, stare, photograph it, and share it on social media. That organic amplification does not happen with a static billboard that people walk past every day without noticing.
The Monster AdVan: 35sqm of Mobile Impact
Our flagship Monster AdVan carries the largest mobile LED screen in Europe at 35 square metres. No other mobile billboard in the UK or Europe comes close. The screen supports full motion video, 3D anamorphic content, and real-time content updates, all GPS-tracked and reported.
When you compare a 35sqm moving video screen to a static 48-sheet printed poster, the difference in impact is not subtle. The Monster AdVan is designed for campaigns where you need people to stop, look, and remember. Product launches, film premieres, brand activations, and high-profile events.
Starting from £850 per day outside London and £999 per day in London, the Monster AdVan delivers an experience that no static billboard can match. Learn more about the digital advan.
ROI: Which Format Delivers Better Return?
Return on investment depends on your campaign objective. If your goal is sustained, low-cost brand awareness over several weeks, static billboards offer an unbeatable cost per impression. A two-week 48-sheet booking at £500 reaching 30,000 people per day delivers roughly 420,000 impressions at a CPM of around £1.20. That is very hard to beat in any advertising channel.
If your goal is to create maximum impact in a short timeframe, drive immediate action, or reach people in specific locations, mobile billboards deliver stronger ROI. The ability to show video content, target precise locations, and create social media buzz means the impact per impression is significantly higher. Brands regularly report spikes in website traffic, store visits, and social mentions during mobile billboard campaigns that far outweigh the higher day rate.
The smartest campaigns use both. Static billboards build a base of awareness across key locations over several weeks. A mobile billboard is then deployed for launch days, events, or tactical activations to create peaks of attention on top of that base.
When to Choose a Static Billboard
Static billboards are the right choice when:
- Long-term awareness:You want sustained visibility over several weeks or months in a specific area. Nothing builds local brand recognition like a well-placed billboard that people see every day on their commute.
- Budget efficiency:You need to maximise impressions for the lowest possible cost. Static billboards offer some of the cheapest CPMs in all of advertising.
- Location-specific messaging:Your message is specifically relevant to people in one area, such as directional signage, local store promotion, or area-specific services.
- National campaigns:You are running a multi-site national campaign across dozens or hundreds of locations simultaneously. The logistics and cost of doing this with mobile billboards would be prohibitive.

When to Choose a Mobile Billboard
Mobile billboards are the right choice when:
- Product launches:You are launching something new and want maximum buzz in a short window. A digital advan driving through your target areas on launch day creates immediate impact and social media amplification.
- Events and activations:You need to reach a specific audience gathered at a venue, stadium, festival, or conference. Mobile billboards can be positioned on approach routes for maximum exposure.
- Competitor targeting:You want to advertise directly outside competitor locations. This is one of the most powerful uses of mobile advertising and something static billboards simply cannot do unless there happens to be a billboard site nearby.
- Video and dynamic content:Your creative is a video, animation, or 3D content that needs movement and sound to deliver its full impact. A 35sqm LED screen playing your content at eye level is incomparably more engaging than a printed poster.
- Short-term campaigns:You only need outdoor advertising for a day, a weekend, or a week. Mobile billboards have a one-day minimum, whereas most static sites require a two-week commitment.
- GPS-verified accountability:You need proof of exactly where your advertising appeared. Every mobile billboard campaign comes with GPS route reports, verified impressions, and photographic evidence.
Using Both Formats Together
The most effective outdoor advertising campaigns do not choose between mobile and static. They use both. Here is a practical example of how an integrated campaign might work:
Weeks 1 to 4: Static Foundation
Book 10 x 48-sheet billboards in key commuter locations across your target city. This builds baseline awareness and familiarity with your brand and message over four weeks.
Week 3: Mobile Activation
Deploy a 35sqm Monster AdVan for 3 days during the peak of the campaign. Day one covers the city centre. Day two targets competitor locations. Day three covers a major event venue.
Combined Result
The static billboards create a sustained base of recognition. The mobile activation creates a peak of attention, social buzz, and direct engagement. Together, they deliver both reach and impact at a total cost of £7,500 to £11,000, competitive with most digital campaigns at this scale.
