The difference between a good sale and a poor one is rarely just luck — it's timing and preparation, and both are within your control. Get them right and you can add hundreds of pounds to what your car fetches. Here's how to play 2026.
The best time of year to sell
Demand for used cars follows a fairly reliable rhythm:
- Spring to early summer (March–June) is traditionally the strongest window. Buyers are active, the weather flatters a car, and seasonal models (convertibles, family cars before the holidays) are in demand.
- The weeks before a plate change (late August, late February) can also work well — more on that below.
- Deep winter is usually the weakest, with fewer buyers and dark, unflattering viewings.
If you're not in a rush, aiming for that spring-to-summer sweet spot tends to pay.
Why the September plate change matters
The new "76" plate arrives on 1 September 2026. The moment it does, the market fills with the newest registrations — and overnight, your car can look a year older on paper, even though nothing about it has changed. That perception softens values.
So if you're already leaning towards selling, doing it in July or August often captures a slightly stronger price than waiting until autumn. (For more on how plate timing works, see our guide to the new 76 plate.)
Know your number first
Before you list — or accept any offer — find out what your car is actually worth. It's the single best protection against a low offer, because instant-buyers and part-ex desks are counting on you not knowing.
A free online valuation takes seconds: enter the registration and you get a realistic market estimate based on the car's age, mileage, make and model. Walk into the sale with that figure in your head and you'll negotiate from strength.
Choosing how to sell
There's a trade-off between price and convenience:
- Private sale — usually the highest price, but the most effort: photos, listings, viewings, test drives, haggling and payment safety.
- Online instant-buyers / "we buy any car" services — fast and easy, with a guaranteed offer in minutes; you trade a little money for a lot of convenience.
- Part-exchange at a dealer — easiest of all, but typically the lowest figure, offset only by the simplicity if you're buying your next car there.
There's no wrong answer — it depends on whether your priority is squeezing out every pound or selling by the weekend.
Quick wins that lift the price
Whatever route you pick, a little preparation pays:
- Gather the paperwork — V5C logbook, service history, MOT certificates and receipts. A complete history reassures buyers and supports a higher price.
- Sort the MOT — a long, clean MOT is a selling point; a short one invites haggling. Selling with a fresh MOT often pays for itself.
- Clean it properly, inside and out, and fix the cheap, obvious niggles (a blown bulb, a warning light).
- Be honest — a car with a known, disclosed advisory sells more smoothly than one where the buyer finds a surprise.
The bottom line
The best time to sell in 2026 is the spring-to-summer window, and ideally before the September plate change dents values. Prepare the car, gather the history, and — above all — check what it's worth before you accept a penny. Timing and a realistic number are what turn a quick sale into a good one.
