Radio advertising: plan a UK campaign for 2027

What to take away

Set the objective and the budget frame

Start with the decision you cannot avoid: what does this campaign have to change? A launch needs reach across a wide area. A retailer with stores in twelve towns needs coverage in those towns and nowhere else. A brand defending its position needs frequency against a defined audience.

Write the objective as one sentence with a number in it. A team paying £400 a month in airtime might target 300,000 adult impacts over six weeks in two cities. The number forces the next decision: how much airtime that buys.

One sentence is enough: an objective with three clauses is three jobs, and the campaign will do none well. Date it and use it as the test every later choice must pass.

A written objective also eases handover, because the buying team can see which decisions are settled. The structure in this radio advertising strategy framework separates the choices that belong at planning stage from those that belong to the buyer.

Reach, frequency or response

Reach campaigns buy across several stations to touch many people once or twice. Frequency campaigns buy fewer stations, or dayparts, and repeat. Response campaigns put spots next to a clear call to action and measure the result.

Most UK radio plans mix reach and frequency. The mix depends on how new the message is. A new brand needs more frequency than a known one, because the first few exposures only establish who is speaking.

Budget talks often start before the objective is settled, which is how plans end up cut in review. A target tied to a business outcome survives a hard quarter better than a schedule with no purpose. Fix the objective first, then let it decide the station list, the dayparts and the length of the flight.

If the campaign sits inside a wider paid media plan, agree early how radio relates to search, social and out of home. This radio advertising channel strategy helps you decide when radio leads and when it supports.

Build the budget in three lines

Airtime is the visible cost. Production is the hidden one, and it is not small: scripts, voice talent, music licences and studio time. Measurement is the third line, covering tracking, response handling and any brand lift work.

The split between these lines depends on how many versions you produce. A campaign with ten versions of a script will spend far more on production.

As an indicative guide for 2027, UK commercial radio airtime typically costs between £2 and £12 per thousand listeners for local stations, and £5 to £30 for national stations, depending on daypart and demand. These are typical ranges, not fixed rates.

Airtime rates move with station, daypart and season, so ask for the schedule in writing with weeks and dayparts itemised. That document is what you check the invoice against. Ask too whether the rate includes production support, because some packages bundle studio time and others do not.

Set the budget in pounds and hold a contingency. A team working to a £12,000 airtime budget might hold £1,200 back for extra spots or a second script. Buying early usually costs less than buying late, and a strong quarter for a station can push prices up.

Plan coverage, stations and formats

Coverage is the first technical question, and it has a simple answer. RAJAR publishes quarterly listening data plus station coverage and mapping data, and its MIDAS survey covers internet-delivered audio, so you can compare broadcast and digital reach before you commit: RAJAR station mapping and coverage data is the starting point.

Build a longlist from coverage, then cut it. Stations that do not overlap your trading area come out first. Stations whose audience skews away from your buyer come out next. What remains is your buy list.

List every postcode you trade from before opening a coverage map. A station that covers four of your twelve towns earns its place only if those four towns carry most of the revenue. Coverage is a revenue question dressed as a technical one.

Audience data tells you who is listening, not just how many. Age, social grade and where people listen all shape whether a station matches your buyer. A station with a smaller but better-matched audience often outperforms a larger, broader one.

Choose between commercial radio and digital audio

Commercial analogue and digital radio still delivers mass reach in the UK. The main groups are Global, whose stations include Heart, Capital, Classic FM, LBC and Smooth; Bauer Media Audio UK, with Absolute Radio, Magic, Kiss and Greatest Hits Radio; and News Broadcasting, which owns talkSPORT and Virgin Radio. Digital audio adds tight targeting and often lower entry costs, and it is bought through a different set of doors: Spotify, podcast specialists such as Acast, and digital audio exchanges such as DAX, Global's own platform. Neither route is automatically better.

Digital audio suits audiences hard to reach on broadcast, and can be bought by interest or programme.

Broadcast radio suits broad regional coverage and local trust. Airtime is bought from whoever sells it: Global and Bauer Media Audio UK sell their own national inventory, while smaller stations are represented by separate sales houses, so ask early who you will actually book with. Many plans run both routes, with broadcast carrying reach and digital audio carrying the niche. One script usually serves both, though the call to action may need to change if the listening context changes.

Whatever the mix, the creative standards for digital formats still apply. IAB UK's native distribution creative best practice sets out principles that translate well to audio: be clear who is speaking, fit the format, and do not disguise the ad.

Pick dayparts, spot lengths and sponsorship

Dayparts change who hears the message. Breakfast reaches commuters and parents on the school run. Mid-morning reaches people at work or at home. Drive time reaches the return journey. Pick the dayparts that match when your buyer can act, not the cheapest rate.

Spot lengths are usually 10, 20, 30 or 40 seconds. Ten seconds suits a reminder for a known brand. Thirty seconds gives room for a proposition and a reason to believe. Longer spots cost more airtime and often more production.

Sponsorship, including travel and weather, buys association rather than interruption. It works when the programme's audience matches yours and the association makes sense. It is a poor fit when the only link is price. Credits are usually sold in blocks rather than single weeks, so check the minimum term before building sponsorship into the plan.

Media agencies hold planning frameworks for these choices. The IPA's media planning knowledge and best practice is a useful reference when you justify a station or daypart decision to a client or finance team.

If your plan covers several regions, keep the reasoning in one place, because the same question will return when the first results land.

Brief and buy

A brief a producer can act on has four parts: audience, single message, tone, and the action you want. Anything else is optional. If the script cannot be summarised in one line, it is doing too much.

Send the brief in writing, even if you have talked it through on a call. Producers work from the document, and a written brief stops the message drifting between versions. It also gives the clearance team something to check against if a claim needs substantiation.

Audio has no picture, so the writing carries the weight. Say the brand name early and often. Give one reason to believe. End with a clear next step, spoken plainly.

Write for the ear and the format

Write short sentences and read them aloud. If you stumble, the listener will too. Avoid numbers that need mental arithmetic, and avoid lists of features.

Match the script to the spot length, then cut ten per cent. Production teams can stretch a script, but a cramped read sounds rushed and the message suffers.

Use one voice unless there is a reason for two. A single, warm, specific voice usually beats a crowded soundscape. Music should support the mood, not compete with the words.

Read the finished script to someone who does not know the brand. If they cannot repeat the offer back, the script needs another pass before it reaches a studio.

Plan for multiple versions. Rotating two or three scripts across a campaign reduces wear-out. A template helps you keep versions consistent: this radio advertising planning template sets out the fields a producer needs before studio time is booked.

Flight and measurement

Flighting means deciding when spots run and when they pause. Continuous flighting suits always-on brands. Burst flighting suits launches and seasonal peaks. Pulsing, which alternates heavier and lighter weeks, suits brands with steady demand and limited budget.

Buy airtime against the coverage data, not against a station's own summary. Confirm what happens if a spot does not run as booked, because make-goods are easier to claim during the campaign than after it.

Measurement should be agreed before the first spot airs. Common options include response codes, unique landing pages, and pre and post brand tracking. Set the measure that matches the objective, and nothing more. Two measures tracked properly beat six tracked loosely.

Ask for post-campaign analysis as part of the buy, not as an extra. A short report on delivered impacts against the plan is the evidence you need for the next budget round. Book a mid-flight review as well, so the second half can be adjusted while there is still time to act.

For a worked sequence that takes a plan from brief to live campaign, this radio advertising ninety day plan shows how the weeks fit together. It is written for teams running their first full cycle, with buying and production tasks set out in order.

The first week of a campaign is not the time to work out who signs off the script. In the UK, commercial radio copy is cleared by Radiocentre before it can air, and any claim has to meet the BCAP Code, which the Advertising Standards Authority enforces. Before booking airtime, confirm the copy deadline and clearance route, then name the person who gives final approval.

A flight that goes quiet because a script missed clearance is the most expensive kind. Keep the approved script, the schedule and the station contacts in one shared file so everyone uses the same version.

Once the campaign is live, delivery questions take over. Agree the copy deadlines, the clearance route through Radiocentre and the make-good procedure before the first spot is booked, rather than afterwards.

If your team needs to build these skills formally, CIM runs strategy and planning training that covers objective setting and media planning.

For B2B campaigns, LinkedIn's advertising best practice guidance is worth reading alongside your radio plan, because the two channels often share an audience and a message.

Glossary

Common questions

How much should a small UK business spend on radio?

There is no fixed minimum, but entry costs are set by station and daypart rather than by a national rule. A local advertiser paying £400 a month can buy a modest run of off-peak spots on one station. Judge the figure against the response you need, not against a benchmark.

Is radio still worth buying in 2027?

Commercial radio and digital audio together still deliver mass reach in the UK, and audio is usually cheaper per thousand listeners than television. The honest answer depends on your audience: check RAJAR coverage for your area before deciding, and test with a measured pilot if the data is unclear.

Should the plan use broadcast radio or digital audio?

Use broadcast when you need broad regional reach and local trust. Use digital audio when you need tight targeting or a niche audience. Many campaigns run both, with one carrying reach and the other precision, and the split reviewed after the first flight.

How long before a campaign goes live?

Allow at least four to six weeks for a straightforward campaign: two weeks for planning and buying, two weeks for creative production and clearance, and a buffer for revisions. Complex campaigns with multiple versions or sponsorship need longer, and clearance takes longer when a claim needs substantiation.
