Last updated: July 2026 — every price on this page was checked against the named UK sources on 8 July 2026.
A head gasket replacement costs around £721 on average in the UK, and £700–£830 on a Nissan Qashqai — Nissan jobs average £816.26 on FixMyCar, Checkatrade lists Nissan at around £700, and ClickMechanic’s Qashqai labour-only figure is £827 (2026 prices).
This is one of the biggest labour jobs in car repair — 8–10 hours or more — and on older Qashqais the maths can favour scrapping instead. Both sides below.
Qashqai head gasket cost across sources
| Figure | Price | Source |
|---|---|---|
| UK average, all cars | £721 | FixMyCar and RAC |
| Nissan (make average) | £816.26 | FixMyCar |
| Nissan, supply and install | ~£700 | Checkatrade |
| Nissan range | £400–£1,000 | Bumper |
| Qashqai (labour only, no parts) | £827 | ClickMechanic |
| UK range, complex cases | £500–£2,000+ | ClickMechanic |
A note on honesty: no source publishes a complete parts-and-labour price specifically for the Qashqai. The closest published data is ClickMechanic’s related Qashqai+2, where 1.5-litre variants run £474–£537 at an independent and £769–£866 at a dealer, with parts at £161–£222 and 6–7 hours of labour.
Spotting it early: the symptoms that matter
The classic head gasket signature: white exhaust smoke, a mayonnaise-like residue under the oil filler cap, unexplained coolant loss, overheating, and bubbles in the coolant expansion tank with the engine running. Any two together justify stopping the car and booking a pressure test. Catching it at this stage — before repeated overheating warps the head — is the single biggest factor in which half of this page’s price range you land in. A £50–£100 diagnostic test is trivial insurance against guessing wrong.
Parts vs labour: why a £20 gasket costs £700+
Bumper puts it plainly: the gasket itself may cost £20, but fitting it means extensive disassembly of the top of the engine. ClickMechanic schedules 8–10 hours; Checkatrade says six hours to a few days. At £40–£80 per hour, labour alone is £320–£800 — plus cylinder head bolts, oil, filter and coolant, all of which must be renewed (ClickMechanic lists them in its estimates). If the head itself is warped and needs skimming or replacing, bills climb well past £1,000.
Repair or scrap? The honest question
Every pricing source raises it: ClickMechanic notes the repair can exceed the value of the car, “which usually means it’s the end of the road for the vehicle”; Checkatrade says mechanics may suggest scrapping lower-value cars; Bumper says the same for older, heavily worn engines. For a 2010s Qashqai worth £2,000–£4,000, a £700–£1,000 head gasket bill can still make sense; add a warped head or overheating damage and it often does not. Get the diagnosis (compression or leak-down test) before authorising the full job.
What affects the price?
- Head condition — skimming or replacing a warped head is the big escalation past £1,000.
- Engine variant — diesel dCi and petrol units differ in access and parts.
- Hours quoted — the same job spans 6 hours to days across sources; ask what is assumed.
- What is renewed alongside — head bolts, oil, filter and coolant are mandatory, not extras.
- Location — £50–£100 hourly in cities against £35–£50 in smaller towns (ClickMechanic).
Frequently asked questions
How long does a Qashqai head gasket job take?
ClickMechanic quotes 8–10 hours of disassembly and rebuild for head gasket work; Checkatrade’s band is six hours to a few days. Expect to lose the car for several days including diagnosis.
What are the signs the head gasket has gone?
White exhaust smoke, mayonnaise-like residue under the oil cap, overheating, coolant loss without visible leaks and bubbles in the expansion tank — get a pressure test to confirm before committing to the job.
Can I drive with a blown head gasket?
You risk turning a £700 job into a dead engine — combustion gases and coolant mixing cause overheating and warping. If the gasket is confirmed gone, recover the car rather than drive it.
Is it worth fixing on an older Qashqai?
Compare the full quote (including any head skim) against the car’s value and condition. Sources agree that when the repair exceeds the car’s worth, scrapping or selling for spares is the rational route — there is no shame in that maths.
