When Is the Best Time to Sell Your Car in the UK?

When you sell your car matters almost as much as what car you are selling. The UK used car market follows predictable seasonal patterns, and aligning your sale with these cycles can put hundreds — sometimes thousands — of extra pounds in your pocket.

Beyond seasonality, there are key depreciation milestones, mileage thresholds, and market conditions that create the perfect windows to sell. Here are 8 strategies for timing your sale to maximise value.

1. Seasonal Patterns: Spring Is King

The UK used car market follows a clear seasonal pattern. Spring (March through May) is consistently the strongest period for selling, driven by several factors:

• Tax refund season puts cash in buyers' pockets
• Longer days and better weather make viewings more appealing
• The March plate change creates a buzz around car buying generally
• People plan for summer road trips and holidays

Winter (November through January) is typically the weakest period. Fewer buyers are active, weather discourages viewings, and Christmas spending reduces budgets. If you can avoid selling in December, do so.

2. Before Major Depreciation Milestones

Cars do not depreciate at a steady rate. There are specific milestones where value drops sharply:

• 3 years old — A wave of PCP returns and ex-fleet cars floods the market, pushing values down
• 60,000 miles — Perceived as the threshold between "low mileage" and "high mileage" by many buyers
• New model launch — When the manufacturer releases a facelift or new generation, the outgoing model drops sharply

If your car is approaching any of these milestones, selling just before can preserve significant value.

3. Before or After the MOT?

Always sell with a fresh MOT if possible. A car with 11–12 months of MOT remaining is worth significantly more than one with just 1–2 months left. The cost of an MOT test (maximum £54.85 for cars) is a fraction of the price reduction buyers will demand for a short MOT.

If your car is likely to fail the MOT and the repairs would be expensive, you might choose to sell it before the test — but you will need to price it accordingly and be transparent about the MOT status.

4. Day of the Week: List Mid-Week

Data from major UK car listing sites shows that listings posted on Wednesday or Thursday generate the most enquiries. The reason is simple: buyers browse listings during the week (especially during work breaks) and arrange viewings for the weekend.

Avoid listing on Friday evening or Saturday morning when your advert competes with a flood of new listings. By mid-week, the previous weekend's listings have settled and yours gets more visibility.

5. Plate Change Months (March and September)

The UK's plate change system creates two annual spikes in new car registrations: March (the bigger one) and September. When thousands of new cars hit the road, their owners trade in or sell their old cars, temporarily increasing used car supply and pushing prices slightly down.

However, this also means more buyers are active. The sweet spot is to sell in late February or early March, just before the wave of part-exchanges hits the market, or in late April/May when supply has normalised but demand remains strong.

6. Before Your Warranty Expires

A car with remaining manufacturer warranty is worth significantly more than one without. Warranty gives the buyer peace of mind and protection against expensive repair bills. If your car's warranty is about to expire, consider selling a few months before rather than a few months after — the difference in value can be several hundred pounds.

7. Market Conditions: Sell When Supply Is Low

Used car prices are heavily influenced by supply and demand. When supply shortages occur (as happened post-pandemic when new car production was disrupted), used car prices can spike dramatically. While you cannot predict these events, being aware of market conditions can help you time your sale. If used car prices are elevated due to supply constraints, it is a seller's market — take advantage.

8. End of Month for Dealer Trade-Ins

If you are trading your car in at a dealership rather than selling privately, the end of the month is often the best time. Dealers have monthly sales targets, and towards the end of the month they may offer better trade-in values to close deals and hit their numbers. The last week of a quarter (March, June, September, December) is especially powerful as quarterly targets create additional pressure.

Final Thoughts

The difference between a well-timed and poorly-timed car sale can easily be £500–£1,500 for the exact same car. Sell in spring, sell before key milestones, sell with a fresh MOT, and list mid-week. These simple strategies cost nothing but can significantly increase the price you achieve.

Market conditions vary and past patterns do not guarantee future performance. Always check current market values before listing your car.
