| 6-cylinder RWD | £1,000-£1,800 | £3,000-£7,000+ (engine and drivetrain damage) |
| V8 / 4WD / SUV | £1,500-£2,500 | £5,000-£10,000+ (engine and drivetrain damage) |
[EM-INTERVIEW] based on specialist interviews. The £800-£1,200 you save on fitting can cost you £2,000-£5,000 in engine damage.

✅ Included
⚠️ NOT Included (Extra Cost)
Important Disclaimer [EM-OBSERVED]: "When you supply your own engine, the fitter cannot guarantee its condition. We can install it professionally - but if the engine has internal damage, that is your responsibility. We recommend having the engine inspected before installation or using a supply-and-fit service where the supplier warranties the engine." - UK Engine Specialist Interview #16 [EM-INTERVIEW]

Risks & Caveats of Customer-Supplied Engines
When you supply your own engine, you accept certain risks. Here's what you need to know.
The fitter does not warrant your engine. If the engine has internal damage - even if it was supplied as "tested" - the fitter is not responsible.
Mitigation: Have the engine inspected by a specialist before installation. Or, consider using a supply-and-fit service where the supplier warranties the engine.
You may have sourced an engine that is not compatible with your vehicle - different engine code, different suffix, different emissions spec.
Mitigation: Verify the engine code matches exactly - including the suffix. If you're unsure, have the fitter check before installation.
Your engine may be missing ancillary components - turbo, injectors, alternator, starter, wiring harness.
Mitigation: Confirm with the supplier exactly what is included. Budget for missing ancillaries.
The fitter is responsible for the installation - but if the engine fails due to internal damage, you pay.
Mitigation: Choose a fitter with good reviews. Ask them to check the engine before installation.
