How much does Advertising & PR agencies cost in London? (2026 price guide)
PR retainers for ongoing media relations and press coverage typically cost £1,000-£3,500 per month for a small business, while larger campaigns with events or influencer outreach can run £5,000-£15,000 or more per month. One-off press releases and distribution usually cost £250-£600 each, and advertising campaign management fees are often charged at £500-£2,000 per month on top of the media spend itself.
Prices depend mainly on the scale and duration of a campaign, the media channels targeted (print, broadcast, online, social), whether paid advertising spend is managed alongside PR, and the agency's track record and media contacts in the relevant sector. Specialist agencies with strong sector relationships typically command higher fees than generalists.
Agreeing measurable outcomes upfront, such as coverage targets or campaign reach, and separating agency fees from media spend in any quote, makes it far easier to compare proposals fairly.
