Autotrader’s October 2026 forecast predicts the combined UK new and used car market will increase transaction numbers by 3.4% this year, marking the most robust sales volume since 2019. The uplift offers dealers an opportunity to boost sales across both new and pre‑owned vehicle inventories.

Key takeaways

• Autotrader forecasts a 3.4% rise in total UK car transactions for 2026.
• Growth rate is the strongest recorded since 2019.
• The increase covers both new‑car and used‑car segments.

Forecast overview

Autotrader’s analysis aggregates data from its online marketplace, dealer listings and vehicle registrations to project annual transaction volumes. The model indicates a 3.4% uplift compared with the previous year, suggesting a modest but notable rebound in overall market activity.

The projection combines sales of brand‑new vehicles with those of used cars, reflecting the total number of transactions rather than monetary value. By treating the market as a single unit, the forecast highlights the overall health of dealer activity across all price points.

Impact on new‑car sales

A rise in total transactions typically translates into higher demand for new models, especially as manufacturers launch refreshed ranges in 2026. Dealers can anticipate increased showroom footfall and a need to secure allocation of popular trims.

Higher turnover may also improve gross profit margins on new stock, provided inventory costs are managed. Dealers should monitor manufacturer incentives that often accompany periods of market growth.

Impact on used‑car sales

Used‑car volumes are expected to mirror the overall market expansion, offering dealers additional opportunities to move trade‑ins and reconditioned stock. The 3.4% increase could offset recent soft spots in specific model segments.

Higher trade‑in volumes can supply a broader selection for resale, potentially reducing the need for external sourcing. Dealers may also benefit from increased pricing power as competition for high‑quality used cars intensifies.

Dealer strategies to capture growth

To capitalise on the forecasted rise, dealers should review inventory mix, ensuring a balanced offering of both new arrivals and high‑demand used vehicles. Leveraging online listings can extend reach to price‑sensitive buyers.

Investing in rapid appraisal tools and efficient finance processes can shorten the sales cycle, allowing dealers to handle the higher transaction volume without compromising service quality.

What this means for dealers

The 3.4% growth forecast signals a favourable environment for dealer profitability, but success will depend on inventory readiness and efficient transaction handling. Dealers that align stock with consumer demand and streamline paperwork are likely to capture a larger share of the expected sales uplift.

Monitoring local market trends and adapting promotional offers to both new and used segments will help maintain momentum as the market moves beyond the post‑pandemic recovery phase.

Frequently asked questions

What does a 3.4% increase in transactions mean for dealer turnover?

A 3.4% rise in the number of vehicle sales suggests that dealers could see a comparable uplift in revenue, assuming average transaction values remain stable. The increase may improve overall profitability if costs are managed effectively.

Will the growth affect new‑car, used‑car, or both segments?

The forecast covers the combined market, so both new‑car and used‑car segments are expected to experience higher transaction volumes. Dealers should therefore prepare inventory strategies for each side of the business.

How can dealers prepare for the projected sales boost?

Dealers should ensure a balanced stock mix, optimise online presence, and streamline finance and appraisal processes. Proactive engagement with manufacturers and supplier networks will also help secure the right allocations to meet rising demand.
