Retail brands risk leaving profitable growth on the table by underinvesting in advertising

New WPP Media UK analysis commissioned by Thinkbox suggests retail brands have significant scope to increase media investment while still generating profitable returns.

The study, The Growth Gap, finds UK brands are collectively leaving £32bn of potential profit growth behind, with many businesses stopping investment long before media spend ceases to be profitable. For retail brands, the opportunity is particularly clear, with analysis showing +131% profitable headroom versus the current average annual media investment.

The findings come as retailers continue to face pressure on margins, trading performance and consumer confidence. In this environment, the research suggests a narrow focus on short-term efficiency metrics risks limiting total profit growth.

Across all sectors, the average brand could double its current advertising investment and still generate a profitable return. Average annual brand media investment currently sits at £15m, while the saturation point - when each additional £1 of investment generates less than £1 in profit - is £30m.

The research is based on an analysis of 624 brands and more than 7,400 campaign scenarios, building on the econometric database behind Profit Ability 2, which covers 141 brands, £1.8bn of media spend and 10 media channels.

Key findings include:

• UK brands are leaving an estimated £32bn of potential profit growth behind.

• Retail brands show +131% profitable headroom versus current average annual media investment.

• The average brand could double advertising investment and still generate a profitable return.

• Increasing advertising spend up to the point where every additional £1 still returns at least £1 profit could unlock 11% headline profit growth.

• Advertising delivers an average short-term profit ROI of £3.15, rising to £6.93 in the long term for retailers earning over £1bn annual revenue. For retailers with under £1bn in annual revenue, advertising delivers £1.66 in the short-term, rising to £3.37 when full profit effects are included.

The analysis also challenges the idea that brand investment only pays back in the long term, showing that the effects of advertising can contribute within current planning cycles when investment is timed and allocated effectively.

James Parnum, EVP, Planning at WPP Media says: “When trading is soft, it's natural to cut back and focus on the short term. But for retailers, this means walking away from growth just when they need it most. This research shows that the average retailer could double its media investment and confidently return profit. While others pull back, the brands that keep investing in their brand will be the ones that pull ahead.”
