Advertise on Capital FM with One Day Agency
A Capital FM advertising agency with national reach.
One Day Agency helps brands reach the UK's youth and young adult audience through targeted Capital FM advertising across DAB, FM, and digital audio channels. Capital FM is the UK's No.1 Hit Music Station, owned by Global, reaching 9.2 million listeners every week across FM, DAB, and the Global Player app.
One Day Agency manages the full process: audience research, campaign strategy, airtime planning, creative direction, and placement across Capital FM's national and regional network. Capital FM's audience is predominantly young, urban, and commercially active: 9.2 million weekly listeners, 59% female, with 47% aged 15–34 and 54% classified as ABC1 adults.
Advertising on Capital FM extends beyond traditional radio. Through DAX, Global's digital audio platform, brands can reach Capital FM listeners on smart speakers, the Global Player app, and connected devices, with targeting by location, behaviour, and time of day. Sibling stations within the Capital network, including Capital XTRA, Capital Dance, and Capital Chill, offer further audience segmentation. For brands exploring radio advertising more broadly, or looking at podcast advertising and Spotify advertising as complementary channels, One Day Agency plans across all of them together.
Why advertise on Capital FM?
Capital FM is the UK's primary broadcast radio channel for brands targeting 18 to 34 year olds. This is an audience that is significantly under-indexed on linear TV and increasingly difficult to reach through traditional broadcast. The audience is large, young, and financially active.
Capital FM reaches 9.2 million listeners every week across the UK, on FM in every major city and nationally on DAB.
47% of Capital FM's audience are aged 15–34, making it the UK's primary radio channel for brands targeting younger adults.
54% of Capital FM's audience are ABC1 adults, the most commercially active socioeconomic group for consumer spending.
59% of Capital FM's audience are female, which makes it one of the most effective broadcast channels for brands where the purchase decision skews female.
Capital FM advertising formats.
Advertising on Capital FM is available in several formats, from traditional airtime spots to digital audio targeting and live event sponsorships. One Day Agency can plan across all of them within a single campaign, or focus on the format that best fits the brief.

Radio Spots (Airtime)
Radio spots are the standard format for advertising on Capital FM. The industry norm is 30 seconds, but Capital FM also accommodates 10, 20, 40, and 60-second options, depending on the campaign objective and budget. Spots are broadcast across Capital FM's national DAB network and its regional FM transmitters, giving brands the flexibility to run a national campaign or to target individual markets: Capital London (95.8FM), Capital Manchester (102FM), or Capital Birmingham (102.2FM), for example.
Radio spots work well for brand awareness, direct response campaigns, and promotional activity. The format is immediate, difficult to skip, and reaches listeners at high-attention moments: commuting, working out, cooking. One Day Agency plans spot campaigns around frequency and timing to ensure the message lands with the right audience at the right time.

DAX: Digital Audio Advertising
DAX is Global's proprietary digital audio advertising platform. It allows brands to reach Capital FM listeners beyond the traditional radio broadcast, on the Global Player app, on Amazon Alexa and Sonos smart speakers, and across other connected devices and streaming environments.
Where traditional radio delivers broad reach, DAX delivers precision. Targeting options include geographic (down to a 1km radius), demographic, contextual (weather, time of day, playlist type), and behavioural. Dynamic creative capabilities mean the same campaign can serve different messages to different audience segments automatically. A London listener hears one message; a Manchester listener hears another.
DAX supports both programmatic buying and direct deals, and is most effective when it runs alongside traditional Capital FM airtime. The two formats reach the same audience across different touchpoints, extending reach and reinforcing the message from the radio in the morning to the app on the commute.

![Sponsorship]()
Sponsorship
Capital FM sponsorships give brands consistent, high-context presence around the station's most-listened content. Show sponsorships and segment idents are available across Capital FM's schedule, including the breakfast show and the Capital FM chart countdown, programming that commands high daily habitual listening.
Editorial adjacency drives higher brand recall than standalone airtime, because listeners associate the brand with content they already value. For brands seeking scale events, Capital's Summertime Ball at Wembley Stadium and Jingle Bell Ball at The O2 offer event-based sponsorship with a live audience in the tens of thousands, alongside significant broadcast and social coverage.
Sponsorships are best suited to brands seeking consistent, long-form presence rather than short campaign bursts.

![Capital Buzz]()
Capital Buzz
Capital Buzz is Capital FM's Gen Z content vertical, operating within the Capital brand across digital and social channels. It covers pop culture, music news, celebrity content, and trending social moments: the kind of content that the 16 to 24 year old audience actively seeks rather than passively receives.
Brand integration within Capital Buzz is relevant for brands specifically targeting the under-25 segment and looking for placements that feel native to the content environment, rather than traditional ad breaks.
How One Day Agency approaches Capital FM advertising.
Going direct to Global for Capital FM airtime is possible, but a media agency adds value at every stage. One Day Agency provides independent planning. The recommendation to advertise on Capital FM comes from analysis of the brief and the audience, not from a relationship with a single media owner. One Day Agency is not tied to any station or media group, which means Capital FM is recommended when it genuinely fits, and not recommended when it does not.
Where Capital FM advertising is most effective is when it runs alongside complementary channels. Paid social, out-of-home advertising, and digital channels can reinforce the same brand message and extend reach beyond the radio audience. One Day Agency plans all channels together from the outset, so airtime and creative are designed to work together from the start.
There is also significant value in breadth. Capital FM is part of Global's wider radio advertising portfolio, which includes Heart FM advertising, LBC, Smooth Radio, Classic FM, Radio X, Capital XTRA, and Capital Dance. DAX extends that reach further into digital audio. One Day Agency can plan across the full Global network, combine Global stations with independent UK stations, or build a multi-station schedule that reaches the broadest possible audience within a single campaign budget.
One Day Agency can also advise on radio commercial production. Writing for the ear is a different discipline to writing for the screen. Pacing, tone, and structure all need to be adapted for an audio-only format, and One Day Agency works with production partners to ensure the creative is built for Capital FM's audience.

Media Planning & Buying
“Capital FM is where culture moves first. The audience is young, engaged, and harder to reach through traditional broadcast channels. When you place a brand on Capital well, you're not just buying airtime, you're buying relevance. We plan Capital FM campaigns to earn that position, combining airtime with DAX targeting so the message follows the listener from the radio in the morning to their phone on the commute.”
Ricardo Seixas, Founder and CEO, One Day Agency
Frequently Asked Questions.
-
Capital FM carries commercial advertising across its national DAB and regional FM networks. Airtime is sold through Global, Capital FM's parent company, and can be accessed directly or through accredited media agencies such as One Day Agency. Advertising options include traditional radio spots, digital audio through DAX, show sponsorships, and event-based partnerships.
-
Capital FM advertising costs are bespoke and depend on the transmitter or network coverage, the time of day, the ad length, and campaign duration. Regional campaigns on a single transmitter sit at a different investment level to a full national campaign. One Day Agency provides bespoke media plans based on your audience, geography, and budget. For context on radio advertising costs, see our guide to how much a radio advert costs.
-
DAX is Global's digital audio advertising platform. It allows brands to reach Capital FM listeners beyond the traditional radio broadcast, on the Global Player app, on smart speakers such as Amazon Alexa and Sonos, and across other connected devices. DAX supports programmatic buying, dynamic creative, and hyper-targeted audience segmentation that is not possible with traditional airtime alone. Most Capital FM campaigns benefit from combining DAX with traditional spot activity to extend reach and maintain message consistency across listening environments.
-
Capital FM reaches 9.2 million listeners every week across the UK. The audience is predominantly female (59%), with 47% aged 15–34 and 54% classified as ABC1 adults. Capital FM is one of the most effective broadcast channels in the UK for reaching younger adult audiences at scale.
-
Capital FM advertising is available both nationally, across the full DAB network, and regionally, on specific FM transmitters. Brands can target individual cities, including Capital London (95.8FM), Capital Manchester (102FM), and Capital Birmingham (102.2FM), or run a full national campaign. One Day Agency can also plan phased rollouts, where a campaign launches regionally and scales nationally as results are established.
-
The industry standard for radio advertising is 30 seconds, and this is the most common format on Capital FM. Shorter formats of 10 and 20 seconds work well for high-frequency reminder campaigns; 40 and 60-second formats allow more narrative. One Day Agency advises on the right length based on the campaign objective and budget. See our guide to how much a radio advert costs for more detail.

Capital FM is part of Global's broader portfolio, which includes Heart FM, Smooth Radio, LBC, Classic FM, Radio X, Capital XTRA, and Capital Dance.
