Scrappage Scheme vs Part-Exchange 2026: Which Gets You More for Your Old Car
Replacing an old car usually means choosing between a manufacturer scrappage incentive and a standard dealer part-exchange. The two work very differently, and the better deal depends on your car's condition and the specific offer on the table. This guide explains the mechanics of each and works through an example.
TL;DR -- 30-Second Summary
- • Scrappage schemes: fixed cash incentive for permanently scrapping an eligible old car
- • Part-exchange: negotiable trade-in value, no scrapping requirement, dealer resells the car
- • No single UK-wide scrappage scheme in 2026 — offers are manufacturer-led and change often
- • Scrappage cash can exceed true trade value, subsidised to hit new-car and EV sales targets
- • Always benchmark both against an independent online valuation before accepting either
Side-by-Side Comparison
| Feature | Scrappage Scheme | Part-Exchange |
|---|---|---|
| What happens to your old car | Permanently scrapped or recycled | Resold by the dealer |
| Eligibility criteria | Minimum age, ownership period, MOT history | None; any car the dealer will trade in |
| Value offered | Fixed incentive, set by the scheme | Based on market/trade condition, negotiable |
| Typically funded by | Manufacturer subsidy | Dealer, based on resale expectation |
| Availability | Time-limited manufacturer promotions | Available at any dealer, any time |
| Convenience | Both are single-transaction, no separate buyer needed | |
Worked Example: A 10-Year-Old Petrol Car
Suppose a 10-year-old petrol car has an independent trade valuation of around GBP 1,800 and a private-sale value of around GBP 2,400. A dealer offers a part-exchange of GBP 1,700 toward a new car. Separately, a manufacturer is running a scrappage promotion offering a flat GBP 3,000 toward the same new car if the old vehicle is scrapped, provided it meets the scheme's age and MOT criteria.
| Option | Value received | Trade-off |
|---|---|---|
| Private sale | about GBP 2,400 | Time, effort, payment risk |
| Dealer part-exchange | GBP 1,700 | Below both trade and private value, but negotiable |
| Manufacturer scrappage | GBP 3,000 | Car must be scrapped, only usable toward that new car |
Here the scrappage offer beats both part-exchange and the private-sale estimate by a clear margin, GBP 600 more than selling privately and GBP 1,300 more than the dealer's part-exchange offer, because the manufacturer is subsidising it to win a new car sale. That will not always be the case: a newer, higher-value car might fetch far more privately or in part-exchange than a fixed scrappage incentive, so always compare all three routes before committing, and remember scrappage permanently removes the option to sell the car elsewhere.
When a Scrappage Scheme Wins
A scrappage scheme tends to win for an older, lower-value car that would fetch little on the open market or in part-exchange, especially if it meets a manufacturer's eligibility criteria and the promotion happens to be running when you are ready to buy. Because these incentives are subsidised to hit new-car and EV sales targets, the cash on offer can be well above what the car is genuinely worth.
It also suits buyers who are committed to buying from that specific manufacturer anyway, so the restriction of only being usable toward one new car is not a real drawback.
When Part-Exchange Wins
Part-exchange tends to win for a newer or higher-value car that does not meet scrappage eligibility criteria, or where no manufacturer promotion is currently running. It also wins when you want maximum flexibility over which new car and dealer you buy from, since part-exchange is available everywhere and is not tied to a single scheme.
It is also the better route if you would rather keep the option of shopping the trade-in value around multiple dealers, or benchmarking it against an independent online valuation, to make sure you are not leaving money on the table.
