Building a segment-driven strategy in a competitive automotive market

Challenge

The UK automotive parts and accessories market represents approximately 15.7 million consumers – but it is fragmented, price-sensitive and increasingly digital.

The client faced several commercial tensions:

• Strong overall brand awareness, but lower awareness among high-value segments 
• Consumers still shopping in-store, yet expressing a growing preference for online purchasing 
• Increasing competition from online-first players and marketplaces 
• High levels of confusion and need for reassurance when buying parts online 

The key question:

How do we prioritise the right audiences and build a strategy that captures 80% of the market’s value?

1. Identifying the segments that drive value

The analysis uncovered ten distinct segments within the UK market, with five core segments accounting for approximately 80% of category value.

Each segment differed in:

• Confidence in vehicle maintenance
• Emotional relationship with their car
• Channel preference
• Sensitivity to price vs reassurance
• Responsiveness to different retail features

This moved the conversation away from “all customers” toward clear strategic priorities.

2. Understanding channel tension

Although many consumers currently purchase in-store, the top value-driving segments show a strong preference for purchasing via website. However, UK consumers also report higher levels of confusion when buying parts online and a stronger need for support.

This revealed a critical growth lever: Bridging compatibility anxiety and building confidence online.

3. Testing the proposition

Clusters evaluated a range of features and service propositions to understand what would genuinely drive appeal and conversion.

The testing showed strong appetite for service-led enhancements such as fitting support, yet awareness of existing services remained limited.

This insight shifted focus from simply adding features to:

• Improving communication
• Elevating reassurance
• Prioritising the benefits that matter most

The commercial impact

The research gave the business clarity in a market worth approximately 15.7 million UK consumers; enabling sharper prioritisation in a large and competitive category.

The segmentation identified five core segments representing c.80% of total market value. This allowed the client to move away from broad targeting and instead focus on the audiences driving the majority of spend.

The work also revealed:

• 60% overall brand awareness in-market, but lower awareness among certain high-value segments with strong conversion once aware.
• Strong loyalty dynamics, with many consumers tending to buy from the same retailer repeatedly.
• A clear gap between current in-store purchasing behaviour and stated preference for buying online via website.
• Significant appetite (c.60%) for service-led propositions such as fitting support, however only 39% were aware of the current offering  

Together, these insights highlighted:

• Where awareness investment would drive the greatest return
• Which segments offered the strongest commercial opportunity
• How proposition communication could unlock existing demand
• Where online experience improvements could reduce purchase friction

Rather than spreading investment across the entire market, the business now has a clear, evidence-based framework for targeting the segments that matter most.

Why it matters

Segmentation is not an academic exercise; when done properly, it:

• Aligns marketing, product and channel teams
• Prevents wasted investment across low-value audiences
• Sharpens messaging
• Increases conversion efficiency
• Drives sustainable growth

This project gave our client a common language for decision-making, and a commercially grounded strategy to compete more effectively in a crowded market.
