The short version
Reconditioned, used or new: the short answer
If your engine has failed, you have three realistic ways to get your vehicle back on the road: a reconditioned engine, a used engine, or a brand-new engine from the manufacturer. For most drivers with a car or van that is a few years old, a reconditioned engine is the sweet spot: it costs far less than new, but unlike a used unit it has been stripped, inspected and rebuilt with worn parts replaced, so you are not simply swapping one high-mileage engine for another.
The right choice depends on your budget, how long you plan to keep the vehicle, and what the car is worth. This guide walks through each option so you can decide with confidence, then confirm the exact engine your vehicle needs.
What each option actually means
Reconditioned engine
A reconditioned engine has been completely stripped down, cleaned and inspected. Worn or damaged components are replaced, tolerances are checked, and the engine is rebuilt and tested before it is sold. The result is an engine restored to a high standard, rather than one judged purely on mileage. This is the option that balances cost against long-term reliability, which is why it suits the majority of drivers.
Used engine
A used engine is a working unit removed from another vehicle, typically one that has been written off for accident damage rather than a mechanical fault. A good used engine is tested and its history checked before sale, and it is usually the cheapest option up front. The trade-off is that you are buying an engine with existing mileage and wear, so its remaining life is harder to predict than a rebuilt unit.
New engine
A brand-new engine is supplied by the vehicle manufacturer, unused and to original specification. It carries the longest life expectancy and the strongest peace of mind, but it is by some distance the most expensive route. On an older vehicle the cost of a new engine can approach, or even exceed, what the car is worth, which is why new engines are usually only sensible on newer or high-value vehicles.
Reconditioned vs used vs new at a glance
| Factor | Reconditioned | Used | New |
|---|---|---|---|
| Up-front cost | Middle | Lowest | Highest |
| Worn parts replaced | Yes, rebuilt and tested | No | Not applicable |
| Expected lifespan | Long | Variable | Longest |
| Warranty | Yes, as standard | Rarely on private sales | Manufacturer warranty |
| Best for | Most cars and vans | Tight budgets or short term | Newer or high-value vehicles |
Cost: how the three compare
As a rule, a used engine is the lowest up-front cost, a reconditioned engine sits in the middle, and a new engine is the most expensive by a wide margin. What matters is not just the headline price but the cost per year of reliable service you get from it. A cheap used engine that needs replacing again in a year is rarely the saving it first appears to be.
Prices vary a lot by make, model and engine code, so the most useful thing you can do is check the live price for your specific engine. You can browse current reconditioned stock on our engines collection, or jump straight to your make below.
Reliability and how long each lasts
Fitted correctly and maintained with regular servicing, a quality reconditioned engine can last for many years and tens of thousands of miles, comparable to a factory unit. Because worn internals are replaced during the rebuild, you start from a known, restored baseline rather than inheriting someone else's wear.
A used engine can also give good service, but its remaining life depends on how it was treated in its previous vehicle, which you cannot fully verify. A new engine offers the longest expected life, as you would expect for the price.
Warranty
Every reconditioned engine we supply comes with a warranty as standard, giving you cover that a private used-engine sale rarely matches. The exact term is confirmed on your invoice, and our team is on hand throughout the fitting process if your garage has any questions. You can read more about how our engines are rebuilt on our engine reconditioning page.
So which should you buy?
- Choose a reconditioned engine if you want the best balance of price, reliability and warranty, and you plan to keep the vehicle for a few more years. This is the right call for most cars and vans.
- Consider a used engine if you are on the tightest budget, the vehicle is worth relatively little, or you only need it running for the short term.
- Consider a new engine if the vehicle is newer or high-value and you want maximum life and the strongest peace of mind, and the cost still makes sense against the car's worth.
Good to know: Two cars of the same model and year can take different engines. Always confirm the right unit by your engine code, not just make and model.

Frequently asked questions
Is a reconditioned engine as good as new?
A reconditioned engine is rebuilt to a high standard with worn parts replaced and is then tested, so it offers reliability close to a new unit at a fraction of the cost. A brand-new engine still has the longest expected life, but for most vehicles the difference does not justify the price gap.
What is the difference between a used and a reconditioned engine?
A used engine is a tested, working unit taken from another vehicle with its existing mileage and wear. A reconditioned engine has been stripped, inspected and rebuilt with worn components replaced, then tested, which gives it longer expected life and the reassurance of a warranty.
How long does a reconditioned engine last?
Fitted correctly and maintained with regular servicing, a quality reconditioned engine can last for many years and tens of thousands of miles, comparable to a factory unit.
Do I need to return my old engine?
For most engines there is no surcharge or old-unit return required. Where any listing is an exception, it is stated clearly on that product page.
How do I know which engine my vehicle needs?
Match your engine code and have your registration or VIN ready. The easiest way is to enter your number plate into the registration lookup on our homepage, and we will confirm the correct engine for you.
