BVOD Advertising in the UK: How It’s Bought and Used


BVOD (broadcaster video on demand) advertising means ads served inside the UK broadcasters’ own streaming services: ITVX, Channel 4’s streaming service, 5’s streaming service, Sky’s on-demand and UKTV’s U (product names change, so check the current ones). It is the same programming people watch on linear TV, bought by the impression rather than by the impact, with the targeting and frequency controls of digital video. Used well, it is the most reliable way to add lighter and younger viewers to a TV campaign without leaving the broadcast environment.
We buy BVOD alongside linear airtime every week. The difference between a good BVOD buy and a poor one is rarely the CPM on the proposal; it is whether the impressions reach people the linear schedule missed, at a frequency that does something.
What the evidence says TV returns
The most robust UK dataset on this is Profit Ability 2, run for Thinkbox by Ebiquity, EssenceMediacom, Gain Theory, Mindshare and Wavemaker UK. It modelled 141 brands, £1.8bn of media spend, 10 channels and 14 sectors, 2021-2023 data.
Linear TV and BVOD together accounted for 54.7% of all advertising-generated profit in the study, with linear TV alone at 46.6%.
Source: Profit Ability 2, Thinkbox. These are cross-category averages from modelled econometrics, not a forecast for any individual brand. Your own return depends on category, creative, budget and how well the campaign is planned - which is exactly why it is worth modelling before you commit rather than after.
How BVOD is bought: impressions, not impacts
Linear TV is traded in impacts: one person in the target audience watching one commercial, measured by BARB. You pay a cost per thousand impacts (CPT), and the sales house’s station average price moves with demand. BVOD is traded in impressions: one ad served to one device or logged-in account, priced as a cost per thousand impressions (CPM).
That sounds like a small change in vocabulary. It is not. An impression on a living-room TV set may be seen by two or three people; an impression on a phone on the bus is seen by one. A linear impact counts people; a BVOD impression counts ad serves. You cannot divide a BVOD CPM into a linear CPT and declare a winner, and any proposal that does so without explaining the conversion should be sent back.
The other trading differences a buyer needs to know:
- Guaranteed delivery. BVOD is usually booked as a fixed number of impressions against an audience, and the broadcaster serves them across its inventory until the target is met. There is no first-in-break position to buy and no pre-emption in the linear sense.
- Ads are hard to skip. Broadcaster ad breaks in their own players are generally non-skippable, which is why completion rates are high compared with open web video.
- Each broadcaster sells its own streaming inventory, sometimes packaged with linear and sometimes separately. Some sales houses also sell on behalf of partner broadcasters. Arrangements change, so check who currently sells which service before you plan the split.
- Copy lengths follow TV conventions. A 30″ is the standard; shorter and longer lengths are available but the pricing logic is set per broadcaster rather than by the linear spot-length factors (on linear, a 10″ is roughly 0.5 of a 30″ and a 60″ roughly 2.0, and those factors vary by sales house).
Your ad still needs Clearcast clearance, as it would on linear. For the wider trading vocabulary, our TV media buying glossary covers impacts, TVRs and CPT in more detail.
BVOD advertising costs in the UK
We are not going to print a BVOD CPM here, because there isn’t one number. Rate cards exist, but what you pay depends on the broadcaster, the audience, how many targeting layers you add, the time of year, your total commitment with that sales house and whether the BVOD is negotiated alongside linear. A published rate that ignores all of that will mislead you.
What moves the price:
- Targeting layers. A broad run-of-service buy is the cheapest. Each extra filter (age and gender, region, postcode, interest segment, programme genre) usually carries a premium on the CPM. Stack three or four and the effective cost rises quickly while the available audience shrinks.
- Seasonality. Streaming inventory gets tight in the same months linear does, especially the run-up to Christmas and around big live sport. Our TV advertising seasonality guide explains the linear pattern; BVOD broadly follows it.
- Content. Buying into a specific programme or premium live event costs more than letting the broadcaster serve across its catalogue.
- Your deal. Broadcasters want total video share. An advertiser spending across linear and streaming with one sales house has more negotiating weight than one buying BVOD in isolation.
The cheap-looking CPM is often the expensive one. Untargeted impressions served at high frequency to a small group of heavy streamers can hit the booked volume while adding almost no new reach. We judge a BVOD cost on cost per incremental reach point against the target audience, not on the headline CPM. For the linear side of the budget, see our TV advertising costs guide and the ITV1 CPT index.
BVOD audience targeting
BVOD targeting is more granular than linear because most broadcaster streaming services require viewers to register. That gives the broadcaster declared age, gender and postcode for the account, plus viewing behaviour. From that they build the targeting options a buyer can use:
- Demographic: age and gender bands, built from registration data.
- Geographic: region, TV area or postcode-level targeting, useful for a retailer with a limited store footprint or a regional test that linear’s macro regions are too coarse for.
- Contextual and genre: drama, entertainment, sport, factual, or specific titles.
- Segments: interest and lifestage audiences the broadcaster models from viewing and third-party data.
- First-party data matching: some broadcasters can match an advertiser’s customer data through a clean room, to target or exclude existing customers.
Be careful with targeting. The registration data describes the account holder, not necessarily who is watching the TV that evening. Narrow audiences cost more per impression and there are fewer of them, so the broadcaster reaches the same people again and again to deliver your booked volume. Our rule: target to remove obvious waste (wrong region, wrong age band for the product), not to build a perfect profile of your customer. Unlike household-level addressable linear such as Sky AdSmart, BVOD targets the streaming account, so the two do different jobs and are often best used together.
BVOD frequency capping
Frequency is where BVOD budgets are most often wasted. A campaign booked against a tight audience with no cap will over-serve the heaviest streamers, because they generate the most ad opportunities. The report will show full delivery; the reach curve will have flattened long before the money ran out.
Each broadcaster lets you set a cap per viewer per day, per week or across the campaign. What you set depends on the job:
- Reach extension after a linear burst: keep the cap low. The point is to find people linear missed, not to hit the same people again.
- Launch or a complex message: allow more exposures over a short period so the message sticks.
- Always-on or response activity: cap weekly and keep it steady, so you are not exhausting a small audience in the first fortnight.
The catch: caps work within one broadcaster, not across them. ITVX does not know how many times Channel 4’s service has shown your ad to the same person, and neither knows about your linear delivery. When a plan runs across three or four services plus linear, the total frequency on the heaviest viewers is higher than any single platform report shows. Split the budget sensibly across broadcasters and set each cap with the others in mind, not in isolation.
BVOD campaign reporting
Broadcasters report BVOD through their own dashboards and post-campaign reports. As a minimum, you should get:
- Delivered impressions against booked, by week and by service.
- Completion rate.
- Estimated unique reach and average frequency, with a note on how reach is modelled.
- Delivery by device, showing how much ran on the TV set compared with mobile, tablet and desktop.
- Delivery by region and by targeting segment, if you paid for targeting.
- CPM achieved and any make-goods for under-delivery.
BARB now measures some broadcaster streaming viewing on TV sets alongside linear, which helps when you want a joined-up view of TV reach across linear and on demand. Coverage and methodology continue to change, so ask what is and isn’t included for each service before you rely on a combined number. Each broadcaster’s own report remains a report on its own delivery, marked by itself.
Reporting should end with a decision: keep the same targeting, loosen it to buy reach more cheaply, change the cap or move budget between services. For response campaigns, set up tracking before launch so you can read web sessions, branded search and conversions against BVOD delivery by region and by day. Our DRTV media buying page covers how we read response across linear and streaming.
BVOD advertising strategy: how we use it
The Thinkbox Profit Ability 2 study (141 brands, £1.8bn of spend, 2021–23) found linear TV and BVOD together generated 54.7% of the profit attributed to advertising. BVOD earns its place in a plan when it has a defined role alongside linear, not when it is a digital line added to make the plan look modern. Examples from how we plan:
Reach lighter viewers after a linear burst
A national linear campaign builds reach quickly among heavier TV viewers, then the reach curve flattens and extra spots mostly add frequency to people who have already seen the ad. Running BVOD with a low cap, in the weeks during and after the burst, goes after the lighter linear viewers who watch the same programmes on demand. This is the most common and most defensible use.
Younger audiences
Younger adults watch less scheduled TV and more on demand. Buying them on linear is expensive: the ITV1 average market CPT for Men 16-34 was £636.70 in January to August 2026, against £14.32 for all Adults (TheHub market price data, as published on our ITV1 CPT index; these are average market prices, and what an advertiser actually pays is usually less). Shifting some of the youth-audience budget into streaming, targeted by age, often builds reach among them more cheaply than chasing the last linear ratings points.
Regional and store-footprint campaigns
A business trading in part of the country can use postcode or regional targeting to put a TV-quality ad in front of only the viewers it can serve. That is tighter than an ITV macro region and a common first step before full regional TV advertising.
Programme alignment and live events
Buying into specific titles or live sport on streaming lets a brand sit next to the content that matters to its audience. Price it carefully; premium content carries a premium.
Testing before a bigger TV commitment
A BVOD test can prove creative and response routes before a linear launch, but only if it delivers enough impressions in a tight enough area to read. A test spread thinly across the country tells you nothing. Our linear TV vs BVOD vs connected TV comparison sets out when each route should lead.
Choosing a BVOD advertising agency
BVOD is sold by the same broadcaster sales houses that sell linear airtime, so the best BVOD buyer is usually a good TV buyer rather than a digital video specialist. When you’re choosing an agency, ask:
- Do they buy linear and BVOD together? The negotiating weight comes from buying total video with each sales house, and the planning only works if one team can see frequency across both.
- How do they compare BVOD with linear? If they put a CPM beside a CPT without explaining the difference, they have not thought about what they are buying.
- How do they judge value? The answer should be incremental reach against your audience, not impressions delivered or a low CPM.
- What will the report tell you? Ask for a sample post-campaign report and check it ends in a recommendation, not a screenshot of a dashboard.
- Are they independent? An agency tied to a trading deal may have reasons to favour one broadcaster’s streaming service. Ours doesn’t; see our independent TV media buying agency page for how we work.

Common questions
What is BVOD advertising?
Broadcaster video on demand - the on-demand players run by the broadcasters themselves, such as ITVX, Channel 4 and Sky. It carries broadcast-standard programming and clearance, is bought on impressions rather than ratings, and can be targeted by demographic, region and device.
Is BVOD a replacement for linear TV?
No. Profit Ability 2 found linear TV alone still accounted for 46.6% of all advertising-generated profit, with linear and BVOD together at 54.7%. BVOD adds targeted, incremental reach - particularly among lighter TV viewers - rather than substituting for the reach linear delivers.
