December 2025 — Insight for UK car dealers

Short Summary

As 2025 draws to a close, UK car dealers are navigating a rapidly changing market driven by growing EV adoption, regulatory shifts and evolving consumer demand. Dealers who act now — by adjusting their stock, pricing and sales strategy — have an opportunity to end the year strong and head into 2026 well-positioned.

Market Snapshot: Strong Q3 Sales But Market Shift Ongoing

According to a recent update from Deloitte UK, new-car sales in the UK climbed by 5.6 % in Q3 2025 compared to the same period last year, bringing year-to-date growth to about 4.2 %.

However, while petrol-powered cars remain the largest share of sales, their slice of the market is shrinking — as buyers increasingly favour hybrids and fully electric models. 

EV Momentum — What It Means for Dealers

The shift towards electric vehicles (EVs) in the UK is accelerating. Projections for 2025–2026 point to a significant rise in battery-electric vehicle (BEV) registrations, pushing EVs to claim a growing share of new-car registration volumes.

For dealers, this means stock decisions, forecourt composition, and sales-team training must increasingly account for EVs and hybrids — especially as buyers become more conscious of emissions, running costs and environmental policy trends.

Why December 2025 Is a Critical Sales Window

Industry guides for 2025 highlight that the end of the year — particularly December — remains one of the best times to sell new cars. Dealerships often ramp up promotions, discounts and financing incentives to hit annual targets and clear outgoing-stock before the new year.

For dealers, this presents a strategic opportunity to clear older stock, offer competitive pricing, and make room for new or in-demand EVs or hybrid models.

Strategic Imperatives for Dealers Heading Into 2026

• 
  
• Reassess vehicle mix: Increase EV and hybrid stock to reflect rising demand for cleaner, lower-emission vehicles.
• Train sales teams: Ensure staff are knowledgeable about EV benefits, charging costs, and long-term ownership implications — to reassure customers and close sales.
• Use December momentum: Leverage year-end sales incentives and consumer urgency to move old-year stock and pre-order or stock up for 2026 demand shifts.
• Communicate transparently: Help customers understand total cost of ownership, EV advantages vs. traditional cars, and potential savings over time.
