Programmatic advertising CPM bands for eight UK regions

What to take away

How to read a UK programmatic advertising CPM benchmark

A programmatic advertising CPM is the price paid per thousand impressions, before or after fees depending on who is quoting. UK agencies rarely quote the same basis twice. Some give a media-only CPM. Others fold in demand-side platform fees, verification, data and management, then present one blended number.

Always ask which costs sit inside the CPM. A £4 media CPM with £2 of tech and data is really a £6 effective CPM. That distinction matters when you compare quotes across agencies and across regions.

The second question is inventory type. Open exchange display, private marketplace deals, preferred deals and connected TV all price differently. A benchmark that mixes them is close to useless for budgeting.

Third, check the measurement window and viewability standard. UK buyers commonly work to the IAB UK and Media Rating Council viewable impression standard, with 70 per cent viewability for display as a working floor. A cheap CPM against low viewability is not cheap.

Fourth, separate brand and performance campaigns. Performance-led buying within retail media or search-adjacent placements behaves differently from upper-funnel display, and the CPM gap can be three or four times.

For a fuller breakdown of what belongs in each line, our costs and pricing explainer walks through the components.

The four numbers behind every quote

Every UK programmatic quote reduces to four figures: media CPM, technology fee, data cost and management fee. Ask for all four separately. If an agency cannot split them, treat the quote as provisional.

What counts as a good CPM

A good CPM is one that delivers your cost per acquisition or brand lift target at an acceptable viewability and brand safety standard. There is no universal good number, and any agency claiming one is simplifying to win the pitch.

CPM ranges by region: Greater London, North West, Scotland, Wales and more

Regional CPM variation in the UK is real but narrower than sector variation. The table below gives working ranges for open exchange display, media-only, based on typical UK buying patterns. Treat them as planning bands rather than quoted rates.

The bands cover eight regions. Northern Ireland, the East Midlands, the East of England and South West England are not banded here, and the bands also exclude technology, data, verification and management fees, which agencies charge on the campaign rather than by region. For a campaign in one of the four unbanded regions, ask each agency for a region-filtered quote on the same inventory type and compare effective CPMs, as set out below.

| Region | Open display CPM | Private marketplace CPM | Typical premium vs North East |

These bands assume standard display formats, UK traffic, and a normal brand safety profile. They shift with seasonality. November and December push CPMs up across every region, sometimes by 30 per cent or more in retail-heavy categories.

Greater London sits at the top for three reasons: more premium publisher inventory is headquartered there, more finance and professional services advertisers bid there, and agency trading desks concentrate buying in the South East. The result is a genuinely more competitive auction.

Scotland and Wales price lower on average, but that average hides pockets of expensive inventory. Scottish news and current affairs publishers, and Welsh-language placements, can command rates closer to London because supply is thin.

Regional targeting is not free. If you buy nationally and filter to a region, you still pay the national auction price. To capture regional rates you need to buy regionally, which usually means smaller volumes and less buying power with a single agency.

How sector shifts UK programmatic advertising costs

Sector is the bigger lever on programmatic advertising costs. A finance brand and a public sector body can buy the same London inventory and pay wildly different rates because of targeting, data and compliance requirements.

Sector CPMs move with targeting, data and compliance requirements, so the pattern below is directional rather than a fixed table.

Finance carries the highest display rates in the UK. Compliance sign-off slows creative rotation, which reduces optimisation frequency, and Financial Conduct Authority rules limit how you can target and retarget. Both push costs up.

B2B is expensive for a different reason: the addressable audience is small. Targeting a specific job title in a specific industry across the UK might reach only a few hundred thousand people, and thin audiences always price higher.

Public sector buying is constrained by budget cycles, procurement rules and data protection duties under UK GDPR and PECR, both regulated by the Information Commissioner's Office (ICO). That keeps CPMs low, but it also means fewer agencies will bid, and those that do often add a compliance premium to management fees rather than media.

Retail is the most seasonal. Outside peak, retail CPMs can be the cheapest on this list. In November, they can double. Plan retail budgets monthly rather than annually.

Automotive sits in the middle, with costs driven by model launch cycles and the length of the consideration period. Regional dealer targeting adds a layer of complexity that usually shows up as a higher management fee rather than a higher CPM.

Why London CPMs diverge from the rest of the UK

Greater London is not just a bigger market. It is a structurally different one, and four forces keep its CPMs above the national average.

First, supply and demand are both concentrated. Most UK national publishers, broadcasters and agency trading desks are headquartered in London. Advertiser demand concentrates there too, so the auction clears at a higher price.

Second, finance and professional services dominate London buying. These are the sectors with the highest willingness to pay, and they set the clearing price for premium placements that other advertisers then have to match.

Third, premium inventory in London is genuinely scarcer per advertiser. National news brands, business titles and transport-adjacent digital placements all attract heavy competition.

Fourth, agency trading desks often buy London inventory on behalf of national clients, which means regional advertisers compete against national budgets for the same impressions.

The practical consequence is that a London-only campaign needs a higher CPM assumption than a national campaign, even though it reaches fewer people. Planners who use a single national CPM across all regions routinely under-budget London by a wide margin.

There is a counterweight. Regional publishers in the North West, Yorkshire and the North East offer strong local audiences at lower rates, and local news brands often deliver better engagement per impression than national inventory. If your objective is regional reach rather than prestige placement, the regional buy is usually more efficient.

The Competition and Markets Authority has taken an interest in digital advertising competition, and the Digital Markets, Competition and Consumers Act 2024 gives it sharper tools. Any structural change to how the largest platforms price inventory would feed through to London CPMs first.

Using platform pricing to sanity-check agency quotes

Before you accept any agency CPM, check it against the platforms you can buy directly. Direct platform buying shows what the auction itself costs, which is the floor beneath any managed service quote.

Google Display Network pricing runs on an auction, and Google's own documentation explains how bids, quality and ad rank interact. The Google Ads auction and bidding documentation is the reference point for how display CPMs are actually set.

In practice, UK Google Display CPMs for standard display sit in a wide band, often £1 to £8 depending on targeting and format. Remarketing and affinity audiences price higher than broad contextual placement.

Meta pricing is auction-driven too, and UK costs vary by objective. Reach and awareness campaigns typically clear lower than conversion campaigns, because conversion objectives attract more competition from performance advertisers.

LinkedIn is the outlier. Its professional targeting and lack of open exchange inventory mean CPMs are far higher than display averages. LinkedIn publishes its own advertising cost guidance; use that as a separate B2B planning check rather than folding it into a display average.

For UK B2B campaigns, LinkedIn CPMs commonly run several times higher than open display. That is not a reason to avoid it, but it is a reason to keep LinkedIn in a separate budget line rather than blending it into a display average.

Using anchors properly

Platform anchors give you a floor and a ceiling. If an agency quotes a managed display CPM below the platform floor, either the inventory is low quality or the quote excludes costs you will pay later.

Building a regional budget model with ONS and IAB UK data

A defensible UK programmatic budget starts with audience size, not with a CPM someone quoted you. Build it in this order.

Worked example: a national B2B campaign

Suppose you want to reach 2 million UK professionals in finance and professional services over a quarter. Your sector CPM band for B2B display is £6 to £15, and you plan a 60/40 split between open display and private marketplace.

At a blended £9 CPM, 2 million impressions cost £18,000 in media. Add technology and data at roughly 25 per cent, and management at 15 per cent, and the effective CPM is around £13. Your total budget lands near £26,000.

Now weight 40 per cent of impressions to Greater London at a £12 CPM and 60 per cent to the rest of the UK at £7. The blended media CPM stays close to £9, so the regional split changes where the budget goes more than the total. That is the kind of adjustment a regional model catches and a flat national CPM misses.

Keeping the model honest

Rebuild the model quarterly. Auction prices, platform policies and regional supply all move, and a model built once will drift out of line within two quarters. Our note on when to rebuild a programmatic cost guide covers the triggers.

Comparing agency quotes without hidden margin

Most UK programmatic quotes are not dishonest, but they are structured to be hard to compare. Your job is to normalise them before you decide.

Start by requesting a breakdown across five lines: media, demand-side platform or technology fee, data and targeting, verification and brand safety, and management. Ask for each as a percentage of media spend and as an absolute figure.

Ask each agency to name the tools behind those lines, because the same fee line means different things on different stacks. The demand-side platform will usually be one such as Google's Display & Video 360, The Trade Desk or Amazon DSP, and verification will usually be Integral Ad Science or DoubleVerify. Two quotes that use the same DSP and verification vendor are far easier to compare line by line.

Then calculate the effective CPM for each quote: total cost divided by total impressions delivered. This is the only number that compares cleanly across agencies.

Next, check what sits outside the fee. Creative production, ad serving, analytics, and any minimum spend commitments are common exclusions. A quote that looks 15 per cent cheaper can be more expensive once these are added.

Ask directly about principal-based buying. Some agencies buy inventory as principal and resell it, which means the margin is inside the media cost and invisible in the fee line. This is legal and common, but you should know when it applies. Our guide to spotting hidden costs sets out the questions to ask.

Finally, compare pricing structures, not just prices. A CPM model, a retainer and a hybrid all shift risk between you and the agency. We compare how these pricing models compared behave over a year, which matters more than the headline rate.

Quote comparison checklist

Red flags in a UK quote

A quote that will not split media from fees, that promises a CPM far below platform floors, or that bundles data into an unexplained line is worth challenging. Ask for the underlying numbers. A good agency will provide them.

Common questions

What is a typical programmatic advertising CPM in the UK?

For open exchange display, media-only, most UK campaigns land between £2 and £12 CPM. Greater London sits at the top of that range and the North East, Wales and Scotland at the bottom. Sector and inventory type move the number more than region does.

Why are London CPMs higher than the rest of the UK?

London concentrates premium publisher supply, advertiser demand and agency trading desks in one market. Finance and professional services advertisers set a high clearing price, and regional buyers compete against national budgets for the same impressions.

How do I compare two agency quotes fairly?

Ask both to split media, technology, data, verification and management, then calculate the effective CPM for each. Compare on total cost per thousand impressions delivered, not on the headline CPM or the management fee alone.

Should I use LinkedIn for UK B2B campaigns?

LinkedIn CPMs are several times higher than open display, but the professional targeting is hard to replicate elsewhere. Keep it as a separate budget line rather than blending it into a display average.

How often should I rebuild my regional budget model?

Quarterly is a sensible default. Auction prices, platform policies and regional supply shift through the year, and a model left unchanged for two quarters will drift away from what you actually pay.

Do public sector campaigns pay lower CPMs?

Yes, generally. Restricted data use under UK GDPR and PECR, tighter budgets and accessibility requirements keep media CPMs low, though agencies often add a compliance premium to management fees.
