Why out of home advertising service standards need a written baseline

What to take away

Why write service standards before you brief a supplier

A service standard is a promise a supplier can be held to. Without one, a late posting becomes an argument about goodwill rather than a credit.

Start with the operations and delivery guide, which shows where standards sit in the wider delivery chain. Then turn each promise into a number: hours to post, hours to repair, days to report.

Keep the list short: five measurable commitments beat twenty vague ones. Each should name an owner and a consequence.

Copy-ready clause: "The supplier will post each site by 06:00 on day one, provide proof of play weekly, and credit the buyer one day's site fee per day a posting, repair or report is late."

For wording, borrow from the Outdoor Advertising Association (OAA) and the IPA/ISBA media contract terms, then adapt them to the site.

Name the measurement method beside each number. A posting deadline proved by a timestamped photograph is enforceable. One proved by the supplier's own report is not.

A timestamped photo should show the full creative, the site reference and the date and time. A play log should list screen ID, campaign ID, spot duration, timestamp to the second, and total plays per loop. A brightness reading should record cd/m² at screen centre and four corners using a calibrated meter, with the method and ambient light noted.

What should the before and after positions cover?

Before signature, record what the supplier claims. After the campaign, record what happened. The table below is an illustrative example for a six-sheet buy at £1,200 per site per month.

The after column is the one that matters. If a supplier cannot evidence a claim, treat it as unproven.

Put a date on the evidence file in the contract. Late evidence should carry the same remedy as a missed posting, otherwise the after column never gets filled in.

How do you check a digital screen against data rules?

Digital out of home that uses cameras, Wi-Fi or mobile identifiers to measure audiences moves into electronic marketing territory. The ICO guide to PECR explains the consent and soft opt-in rules that apply to those communications.

Ask the supplier which lawful basis covers each data flow, and get it in writing before the first pixel goes live.

If the answer is vague, the standard should say the campaign does not run on that screen. Buyers carry the reputational risk even when a contractor operates the hardware.

Does planning consent belong in your standards?

Yes, as a verification step. Advertisement control is a local planning matter, and the Town and Country Planning Act 1990 contains the provisions that govern it.

A site can hold consent for one format and not another. A standard that requires the supplier to confirm consent for the specific structure protects you from a removal notice mid-campaign.

Record the consent reference, the format it covers and the expiry date. Treat any gap as a stop condition. Where consent is pending, the standard should hold the booking rather than guess at the outcome.

How should standards differ between digital and classic sites?

Classic paper and paste sites fail visibly: a torn sheet or a missed posting date is obvious. Digital sites fail quietly, through blank slots, dim panels or loop gaps.

For digital, ask for play logs and brightness readings. For classic, ask for dated photographs and a route sheet.

Brightness and play logs also support renewal pricing, because promised exposure can be compared with delivered exposure.

Treat the Google Ads best practices as a comparison discipline, not an out of home standard.

Who owns the standard when something goes wrong?

The buyer owns the standard even when an agency manages the contract, so name one person who signs off deviations and one who holds the evidence file.

The operating workflow shows how those roles fit into booking, posting and reconciliation.

Review the standard each quarter. Add a clause only after a real failure, and remove any clause nobody has ever tested.

Common questions

How often should service standards be reviewed?

Quarterly is workable for most UK buys. Review sooner if a supplier changes ownership or a screen changes format.

What happens if a supplier misses a posting deadline?

Agree the remedy in advance. For an illustrative £1,200 monthly site fee, one day's pro-rata is about £40. A missed repair window could trigger the same daily credit. A missed weekly report could trigger one week's fee, about £277.

Do these standards apply across the whole United Kingdom?

Advertisement control is devolved in practice, so confirm the position with the planning authority in Scotland, Wales or Northern Ireland before relying on an England-only assumption.

Should proof of play be supplied daily or weekly?

Match the frequency to the campaign length. A two-week burst needs daily evidence; a six-month holding needs weekly reporting.
