What to take away

Map the buying routes before you compare suppliers

Connected TV advertising in the UK is not one market. It is several routes to the same screens, and the route you choose determines which tools you need. Buyers who skip this step compare a managed campaign service with a software licence.

Start with the inventory question. Broadcaster video on demand is sold by UK broadcasters and their own sales houses. ITV Media sells ITVX inventory. Sky Media sells Sky, NOW and Channel 5, and Channel 4 Sales sells Channel 4 streaming. Thinkbox explains how BVOD buying works in practice, including the difference between buying an audience and buying a spot.

That distinction matters when you set targets, because audience-based buying shifts the risk of under-delivery onto the seller.

Aggregators and demand-side platforms sit alongside broadcaster routes. The Trade Desk, Google Display & Video 360, Amazon DSP and Yahoo DSP bundle several publishers into one buying point. That suits advertisers who want reach across multiple streaming services without separate contracts. The trade-off is less control over placement and, often, less transparency about where each impression ran.

Retail media networks have joined the list. Tesco Media and Insight Platform uses Clubcard data. Sainsbury's Nectar360 uses Nectar data. Both sell video and connected TV placements tied to shopping data. They can be a strong fit if your category sells through them. Treat their audience claims with the same scepticism you apply elsewhere.

A structured connected TV advertising supplier comparison keeps scoring consistent once several routes are represented in a longlist. Score inventory access, targeting, measurement and total cost separately, then weight each against your own objective.

Keep the longlist to six or eight. For a UK pilot, start with ITV Media and Sky Media, then add The Trade Desk and Google Display & Video 360. Add Amazon DSP and one retail media network.

Beyond that, evaluation effort grows faster than insight. Suppliers start to notice they are padding out a beauty parade rather than competing for a real budget.

Managed service, self-serve or licence

A managed service means an agency or platform team plans, buys and optimises on your behalf. Sky Media, ITV Media and Channel 4 Sales sell managed campaigns. You pay a fee, often a percentage of media spend, and you gain speed. You lose some visibility, so insist on platform-level reporting in the contract rather than summary dashboards.

Self-serve access puts your team inside the buying interface. ITV Planet V is ITV's programmatic buying platform for ITVX inventory. Roku Ads Manager is a self-serve route in some markets. The Trade Desk and Google Display & Video 360 are self-serve when licensed.

It suits advertisers with existing programmatic skills and enough volume to justify the learning curve. Smaller advertisers should read the IAB UK SME toolkit before committing, because it sets out the practical groundwork that digital advertising guidance assumes.

A technology licence is the third commercial route. You license software, keep the media contract in your name and pay a platform fee.

The Trade Desk and Google Display & Video 360 are common licence choices that give the cleanest cost breakdown. This works only if you have people to run it day to day; without them, the licence becomes an expensive reporting tool.

Hybrid arrangements are common. One supplier may provide the platform while a second runs the campaign, and a third supplies measurement. For example, The Trade Desk buys media, Sky Media supplies BVOD inventory, and DoubleVerify verifies delivery. Write down who is accountable for delivery before you sign anything.

Write the brief before you talk to anyone. Put your objective, audience, budget range, flight dates and reporting requirements in one document. A shared brief is the only way to compare a managed service quote with a licence quote honestly.

Where tools overlap with media

Many connected TV advertising tools are sold as media. A demand-side platform such as The Trade Desk or Google Display & Video 360 charges for access and takes a share of spend.

A verification vendor such as DoubleVerify or Integral Ad Science charges separately for measurement. Ask each supplier to say which part of your invoice is media, which technology, which service.

That single question exposes most hidden margin. If a supplier cannot split the three, treat the quote as incomplete. Our guide to connected TV advertising software selection walks through the evaluation criteria in more detail, including the questions that separate a platform from a reseller.

Ownership of the buying seat matters too. Some platforms buy inventory through their own account on a larger demand-side platform. Amazon DSP is one example, because it buys through Amazon's systems. Your campaign becomes one line in somebody else's ledger. That is not automatically a problem, but you should know it before you agree terms.

Ask for audit rights in the contract. At minimum, you want the ability to check delivery logs and reconcile them against your own ad server. Without that, every discrepancy becomes a negotiation you cannot win.

Compare platform capability on the things that change outcomes

Once the route is clear, compare platforms on a short list of capabilities that affect results. Feature checklists are long and mostly irrelevant. Targeting, frequency control, measurement and inventory access decide whether a campaign works.

Inventory access comes first. A platform that cannot reach ITVX, Channel 4, Sky or Samsung TV Plus is not a candidate, whatever else it offers. Ask for a current list of supply partners in writing and check it against your own audience data rather than the platform's reach estimates.

Frequency management comes second. Connected TV is a shared screen, so repeated exposure irritates households quickly. Confirm how the platform caps impressions per household, whether that cap holds across publishers, and what happens when a household uses several devices on the same service.

Audience data and targeting options

Targeting on connected TV ranges from broad demographic and genre targeting to first-party data matching and household-level segments. The stronger platforms let you upload your own customer data and match it, subject to consent and to the limits of what a shared screen reveals about who is watching.

Ask where the audience data comes from. UK television audience measurement is collected by Barb. The Barb data access guidance explains how agencies and advertisers obtain it.

Any supplier claiming UK television-level audience precision should explain its relationship to that data. For a wider view of the market, see our round-up of connected TV advertising best tools in England.

Competitive tracking is a separate purchase. Platforms such as Nielsen advertising intelligence track ad occurrence and spend across media. That is useful when you need to benchmark share of voice rather than rely on platform-reported figures. Budget for it separately, because it rarely arrives bundled with media.

Third-party segments deserve their own scrutiny. Ask what the segment is built from, how recently it was refreshed and whether it relies on personal data. Vague answers usually mean the segment is modelled rather than observed, and you should price it accordingly.

Creative formats and delivery

Connected TV accepts standard video, skippable and non-skippable in-stream, bumper and, on some services, interactive formats. YouTube documents the full set in its guide to video ad formats, which is worth reading before you brief creative production.

Format availability differs by platform and by publisher. A format that runs on ITVX may not be supported on Channel 4 or Sky Media inventory. Confirm the matrix rather than assume. Build creative in the highest specification you can afford and let platforms downscale, not the reverse.

Delivery also covers ad serving. Check whether the platform supports your existing ad server or requires its own tags. Google Campaign Manager 360, Innovid and Extreme Reach are common ad servers in connected TV. Tag mismatches cause discrepancies that take weeks to resolve, and they tend to surface after the campaign has started.

Consider how many creative variants you can genuinely support. A household that sees the same 30-second spot eight times in a week will remember the annoyance, not the offer. Rotation rules belong in the brief as well as in the contract.

Measurement is the last capability to test. Ask for a sample report before you buy and read the definitions behind each column. Completed views, viewable impressions and reach are three different claims. DoubleVerify and Integral Ad Science can verify some of those claims. Suppliers rarely volunteer which one their dashboard is showing.

Brief creative earlier than you think you need to. Connected TV production, clearance and versioning take longer than social edits. A late asset can cost you a launch slot that was booked weeks in advance.

Price the whole arrangement, not the headline rate

Connected TV pricing is quoted in several ways: cost per thousand impressions, cost per completed view, fixed campaign fees and platform licence fees. Comparing a CPM quote with a licence fee tells you nothing until both are expressed against the same outcome, usually reach or completed views.

Model total cost of ownership. Add media, technology fees, service fees, creative production and the internal time needed to run the account.

A team paying £400 a month for a licence may spend far more on the staff hours behind it. The Trade Desk and Google Display & Video 360 usually charge platform fees as a percentage of media spend. Ask for that percentage in writing.

For UK planning, a small pilot might use £2,000 to £20,000 in media. Technology and service fees can add 15 to 30 per cent on top. Treat those figures as planning examples, not rate cards. Ask each supplier for its own minimum and fee schedule.

Ask what happens at low spend. Some platforms apply monthly minimums that make small campaigns uneconomic. Others charge setup fees that only make sense over a year. A £2,000 pilot can lose a quarter of its value to fees before a single impression runs.

Sanity-check the media rate against your own history. If your search and social channels convert at a known cost, you can set a ceiling for connected TV rather than accept the first CPM you are offered. That ceiling is a commercial judgement, not a market benchmark.

Minimum spend, fees and contract terms

Get minimum spend thresholds in writing, including whether they apply monthly or across the contract term. Ask how fees change if you increase or reduce spend mid-term, and whether the platform charges a fee for the difference.

Contract length matters more than headline price. A twelve-month commitment signed on three months of evidence is a common mistake. Push for a pilot period with defined success measures and a break clause. Our connected TV advertising vendor due diligence checklist sets out the documents to request before any money moves.

Check notice periods and data exit rights. When the contract ends, you should be able to export campaign data and audience segments. If the supplier owns those, you are locked in, and the renewal price will reflect it. Ask for the export format in writing.

Payment terms deserve a line of their own. Ask whether you are billed in arrears on delivery, or upfront against a forecast. Upfront billing ties up cash and weakens your position if delivery falls short in month two.

The checks that protect the budget

The most valuable pre-signature work is verification. Ask for the supplier's registered company details, its data-processing agreement and its approach to brand safety. Check the Companies House record rather than trusting a trading name, because connected TV has a long tail of intermediaries.

Rules also apply. UK advertising is regulated by the Advertising Standards Authority, and data use falls under the Information Commissioner's Office. Read the UK rules and compliance guide before you approve audience targeting that uses personal data, and keep evidence of the consent behind it.

Set a review date before launch. Agree which metrics will trigger a scale-up, a change of tactic or an exit, and write them into the contract. Decisions made in month three are calmer than decisions made in month twelve.

Plan the exit before you need it. A transition checklist, covering data, creative assets, pixel and tag removal, and the handover of any trading seats, keeps a supplier change from costing you a quarter of activity.

Common questions

What is the difference between a connected TV tool and a connected TV provider?

A tool is software you or your agency operate, such as The Trade Desk, Google Display & Video 360 or Innovid. A provider supplies inventory, service or both, such as ITV Media, Sky Media or Tesco Media and Insight Platform. Many companies sell both, so ask for a cost split before comparing quotes.

How much should a small UK advertiser budget for connected TV?

There is no single figure, because minimum spends vary widely between platforms and publishers. Ask each supplier for its minimum in writing. Then model media, technology fees, creative and internal time together. A pilot of £2,000 to £20,000 in media, plus 15 to 30 per cent for fees, is a reasonable planning range. Size it to your smallest viable audience.

Which audience data should I insist on?

Insist on named sources and a lawful basis for any personal data used. UK television audience measurement comes from Barb. Platform-reported figures should be treated as a separate claim. If a supplier cannot explain where its audience segments originate, do not buy them.

How long before I know whether a platform is working?

Set the evaluation window before launch and tie it to your objective, whether that is reach, completed views or incremental sales. A pilot of eight to twelve weeks gives enough data to judge delivery and cost efficiency without committing to an annual contract.
