When Is the Best Time to Sell Your Car in the UK? (2026 Guide)

If you can choose when to sell your car, sell in spring. February to May is when buyer demand is strongest, prices are firmest, and cars move fastest. Avoid late autumn and December if you can. The post-plate-change supply glut, darker evenings, and pre-Christmas budgets all work against sellers.

The short answer

Sell in spring if you can. February to May is when the used car market is most active. Tax refund season puts money in buyers' pockets. Lighter evenings mean more viewings. The March plate change drives a wave of new car sales, and all those part-exchange cars need to find new homes, which keeps the whole market moving.

The worst time is October to December. The September plate change has just flooded the market with fresh stock, buyers are tightening their belts ahead of Christmas, and nobody wants to spend their Saturday afternoon looking at a car in the rain and dark. If you are not in a rush, waiting until February or March will almost always get you a better result.

Month-by-month breakdown

January. A slow start. Most buyers are recovering from Christmas spending. However, dealers are actively restocking after the December slump, so trade-in offers can be reasonable. Private sales are quieter, but serious buyers are out there. Not the worst month, just not the best.

February. The market picks up noticeably. Buyers start thinking about spring purchases. Dealer forecourts are being replenished. If you list your car in February, you catch the early wave of demand before the March rush. A smart time to sell.

March and April. The March plate change drives a surge in new car sales. Thousands of buyers trading in their old cars flood the market with part-exchange stock. This sounds like bad news for sellers, but private demand is also strong. People who cannot afford a new car are looking for used ones, and there are plenty of motivated buyers. Prices are firm.

May and June. The sweet spot. The plate-change chaos has settled, the weather is good, and buyers are happy to come and view cars on light evenings. Demand remains strong and supply has thinned out slightly from the March peak. If you only have one window to sell, this is it.

July and August. Still a strong market. Many buyers want to get sorted before the September plate change makes their shortlist feel outdated. Families buying before the school year are active. Convertibles and sporty cars do particularly well in the summer months.

September. The new 76 plate arrives. Every existing car on the market suddenly looks a year older in buyers' minds. Dealers are flooded with part-exchange stock from the new plate rush. Prices dip, especially on cars that are already three or four years old. If you can, sell before September rather than after.

October and November. The market softens. Post-plate-change supply is still working through the system. Evenings are dark, viewings drop, and buyers become more cautious with Christmas approaching. Sellers who need to move a car quickly will often have to accept less than they would have got in spring.

December. The slowest month of the year for private sales. Most people are focused on Christmas, not car shopping. However, there is a counterintuitive opportunity here. Some dealers are keen to buy stock ahead of the January rush. If you are selling to a dealer rather than privately, December can sometimes produce a reasonable offer from a buyer who knows they need cars on the forecourt for January.

The plate change effect

The UK uses a plate system that changes twice a year. In March, the plate matches the year (a car registered in March 2026 gets a 26 plate). In September, the plate adds 50 (September 2026 is a 76 plate). This system creates two artificial ageing events every year.

The September change is more impactful for sellers. A car registered in August 2024 carries a 24 plate. A car registered just weeks later in September 2024 carries a 74 plate. They are essentially the same age, but the 74 plate signals "newer" to buyers. When the 76 plate arrives in September 2026, every 24-plate car suddenly feels two years old rather than one and a half.

This is not just psychological. Dealers price partly based on plate prefix. Finance companies use it for residual values. Insurance groups reference it. The entire industry treats the plate change as an ageing event, and that feeds directly into what your car is worth.

If your car is on the cusp of looking "old" (a 23 plate in 2026, for example), selling before the September change protects you from the perception shift. Once the new plate is on the road, yours looks a generation behind.

Mileage milestones that matter

Mileage is the other big timing factor, and it is entirely within your control. Buyers and dealers react to round numbers. Selling at 29,000 miles is meaningfully better than selling at 31,000. The car is mechanically identical, but the perceived value is different.

The key thresholds to watch are:

• 30,000 miles. Below this, the car is still considered low mileage for most models. Cross it and you move into "average" territory.
• 50,000 miles. A noticeable step down in buyer enthusiasm. Many warranty and service plans expire around this point.
• 60,000 miles. Often coincides with a major service interval (timing belt, spark plugs, brake fluid). Buyers know a big bill may be coming.
• 80,000 miles. Another significant drop. At this mileage, the car is firmly in "high mileage" territory for anything under ten years old.
• 100,000 miles. The big one. Crossing 100,000 miles triggers a steep drop in perceived value. A car at 98,000 miles will sell for noticeably more than the same car at 102,000 miles. The difference can be £500 to £1,500 depending on the car.

The average UK driver covers 8,000 to 10,000 miles per year. If you know you are approaching a milestone, it is worth selling sooner rather than later. Every month you wait adds mileage and pushes you closer to the next threshold.

Car type and seasonal demand

Not all cars follow the same seasonal pattern. What you are selling matters as much as when you are selling it.

• Convertibles. Sell between March and June. Nobody wants to buy a convertible in November. Spring sunshine makes buyers emotional, and emotional buyers pay more. List it when the weather forecast looks good for the weekend.
• SUVs and 4x4s. Sell between September and November. As the weather turns, buyers start thinking about grip, ground clearance, and school runs on wet roads. A Range Rover Sport listed in October will attract more interest than the same car in May.
• Small cars. Consistent demand year-round. City cars and superminis are bought out of necessity rather than desire, so seasonal swings are smaller. You can sell a Fiesta or Polo at any time of year without losing much.
• Performance cars. Spring and summer. The same psychology as convertibles. Buyers picture themselves on B-roads in the sunshine, not crawling through slush. M3s, Golf Rs, and hot hatches all do better when the sun is out.
• Diesels. Weaker in cities where clean air zones and ULEZ concerns put buyers off. Stronger in rural areas where long commutes make diesel economy attractive. If you are selling a diesel, target buyers outside major cities.

Other timing factors

Beyond the calendar and the odometer, there are several other timing considerations that can add or subtract value.

Sell before your MOT expires. A car with 11 months of MOT is worth more than one with 1 month left. Buyers see a fresh MOT as a signal that the car is mechanically sound. If your MOT is due soon and you are thinking about selling, get it done first. A clean pass with no advisories adds confidence and value. If it fails or comes back with a list of advisories, you know exactly what you are dealing with before setting a price.

Sell before a major service is due. If the car needs a timing belt at 80,000 miles and you are at 78,000, sell now. The next owner will factor in that cost, but they will not deduct as much at 78,000 as they would at 82,000 when the service is overdue.

Sell before warranty expires. A car with six months of manufacturer warranty remaining is more attractive than one with no warranty at all. If your warranty is about to run out, that is a reason to sell sooner rather than later.

Sell when fuel prices spike (if you have an EV or hybrid). When petrol and diesel prices jump, interest in electric and hybrid cars increases. If you are selling an EV or plug-in hybrid, a fuel price spike is your moment. Buyers who were on the fence start actively searching.

When NOT to sell

Sometimes the best move is to wait. Selling at the wrong time can cost you more than you think.

Patience is an underrated tool in the used car market. If you are not forced to sell, choosing your moment carefully is one of the easiest ways to get more money for your car. The car itself does not change, but the market around it does.

The bottom line

The best time to sell your car in the UK is between February and June. Spring demand, longer days, and pre-summer enthusiasm all push prices up. The worst time is October to December, when post-plate-change supply, dark evenings, and Christmas budgets all push prices down.

Beyond the calendar, watch your mileage. Selling before you cross a major milestone protects value. Match your car type to the season. Get your MOT done before listing. And if you have no pressure to sell, wait for the right moment rather than accepting whatever the market offers today.

A few weeks of patience can be worth hundreds of pounds. That is a good return on doing nothing.
