Before you brief a buy, check the out of home advertising advertising rules

What to take away

• The common mistake is signing the site contract before checking whether the advertisement needs express consent. Consent problems surface after the print deadline.
• In England, outdoor advertising consent runs through the Town and Country Planning (Control of Advertisements) (England) Regulations 2007, so the local planning authority is your first call.
• The CAP Code applies to the content, covering claims, prices, offence and children.
• Campaigns aimed at businesses still engage data protection law, so the target list needs the same care as the creative.

Which consent checks come before you book the site?

Planning control for advertisements differs across the UK. England's regime is set by the 2007 Regulations, which classify advertisements and set out when express consent is needed.

Scotland, Wales and Northern Ireland each work to their own framework, so a national buy needs a country-by-country check.

Our guide to out of home advertising UK regulations in England walks through the classes and the local authority process if you need the detail before a booking.

• Confirm the advertisement falls within a deemed consent class, or apply for express consent.
• Check whether the site has an existing consent and whether it covers your format and illumination.
• Ask the local planning authority about Article 4 directions or area-specific restrictions.
• Record the response, the date and the officer's name.

Anything unusual, such as a listed building or a conservation area, needs a qualified planning adviser. This article is general guidance and not legal advice.

What does the CAP Code require of the creative?

The CAP Code is enforced by the Advertising Standards Authority and covers non-broadcast ads, including posters and digital out of home. Rules on substantiation matter most: every objective claim needs evidence before the campaign runs. Price claims need the price to be genuine and available.

• Hold evidence for comparative claims before artwork approval.
• Check that promotions state closing dates and any significant conditions.
• Screen imagery for harm, offence and undue pressure on children.
• Keep a dated approval record for each execution.

Out of home has one extra constraint: the audience cannot look away, and the message may be read by children. Location matters as much as wording, particularly near schools or gambling venues.

Digital screens need the same discipline, plus a check that the creative rotation cannot deliver a message to the wrong audience at the wrong time.

How do B2B targeting and data rules affect the checklist?

Place-based campaigns that reach named individuals at work, through a workplace screen or an event list, sit inside data protection law. B2B marketing is not exempt. The ICO's business-to-business marketing guidance sets out the rules for electronic marketing to businesses, including when consent is required.

• Map every data source before you build the audience.
• Confirm the lawful basis and document it.
• Run new contact lists against your suppression file.
• Offer a simple opt-out in every follow-up touch.
• Review retention periods for the campaign list.

Where a campaign uses a venue's own audience data, confirm who acts as controller.

What does a checked booking look like?

For example, a team buys six roadside panels for four weeks at £650 per panel, which is £3,900. Production and installation add £1,200, and a planning consultant charges £500 to confirm consent for two of the sites. The total is £5,600. That consent fee is under a tenth of the total.

• Consent confirmation with the planning reference.
• CAP Code evidence pack and artwork sign-off.
• Data protection record for any B2B list.
• Insurance and site access conditions.
• Signed contract with a consent warranty.

Common questions

Does a small poster need consent?

Some small formats sit inside a deemed consent class, but size alone does not settle it. Illumination, position and the local authority's area rules all count, so check the class before you print.

Who enforces the CAP Code on out of home?

The Advertising Standards Authority handles complaints and can require changes to a live campaign. Cases are published, so a ruling carries reputational weight.

What changes in Scotland or Wales?

Planning control is devolved, so the classes and application routes differ from England. Run the same checklist with the devolved rules in place.

How long should you keep the approval file?

Keep consent records for the life of the site contract and a reasonable period after it ends, because enforcement can follow the campaign. A qualified planning or legal adviser can set a retention rule for your case.
