Last updated: July 2026 — every price on this page was checked against the named UK sources on 8 July 2026.
A hybrid battery replacement costs around £2,000 and up in the UK (Bumper), with FixMyCar’s published range at £1,000–£5,000 — but the average hybrid battery repair quote is just £346.64, and warranties often cover far more than owners realise.
Before pricing a new pack: check the warranty, then price a repair, then a reconditioned unit — in that order.
Hybrid battery cost by model
| Model | Typical cost | Source |
|---|---|---|
| Toyota Prius (2nd generation) | £1,500–£4,000 | Bumper |
| Toyota Prius (3rd generation) | £2,500–£6,000 | Bumper |
| Toyota Prius (popular models) | £1,000–£1,500 | ClickMechanic |
| Toyota Yaris / C-HR | £3,000–£5,000 | Bumper |
| Mitsubishi Outlander PHEV | £4,000–£7,000 | Bumper |
| BMW 330e / 530e | £4,000–£9,000 | Bumper |
| Mercedes C-Class hybrid | £7,000–£15,000 | Bumper |
A transparency note on the Prius: our two sources disagree — ClickMechanic quotes £1,000–£1,500 for popular models while Bumper’s generation-specific ranges start at £1,500 and reach £6,000. Both are shown as published; the gap likely reflects reconditioned-versus-new packs and generations, so ask exactly what a quote covers.
Repair and recondition before you replace
Hybrid packs are made of modules, and single-module faults are common — which is why FixMyCar’s average hybrid battery repair quote is £346.64 (its Toyota-specific average is £409.33), an order of magnitude below any replacement. FixMyCar also notes reconditioning is often cheaper than replacing, though no approved source publishes a reconditioned-pack price — get written quotes and warranty terms if you go that route.
Warranties: longer than you think
Most hybrids carry an 8-year/100,000-mile battery warranty, with some at 10 years (Bumper). Lexus extends cover to 15 years when serviced at a dealership (Bumper), and Toyota’s scheme adds a year or 10,000 miles of battery cover at each annual service, renewable up to the car’s 15th anniversary, as described by DrivingElectric. On a serviced Toyota or Lexus, a failing pack inside those windows should not be your bill.
How long do hybrid batteries last?
Published figures vary by source: Bumper says 100,000–200,000 miles with proper care, FixMyCar quotes 80,000–100,000 miles, and ClickMechanic says packs are designed for 8–15 years. The consistent story: on a mainstream hybrid, the pack usually outlives the typical ownership period — failures cluster in old, high-mileage cars, exactly where the repair-or-scrap maths needs running.
What affects the price?
- Brand tier — Toyota packs start near £1,500; Mercedes hybrids run £7,000–£15,000 (Bumper).
- Repair vs recondition vs new — £347 average repair against £2,000+ replacement.
- Warranty position — a serviced Toyota can be covered to year 15; check before paying anything.
- PHEV vs full hybrid — plug-in packs are bigger: the Outlander PHEV runs £4,000–£7,000.
- Labour and access — pack location varies by model; ask for the hours in the quote.
Frequently asked questions
How do I know the hybrid battery is failing?
Falling fuel economy, the engine running more than usual, warning lights and reduced electric-only running are the classic signs. A hybrid health check reads the pack’s real state before anyone talks money.
Is a reconditioned hybrid battery a good idea?
It is the standard middle path and FixMyCar notes it is often cheaper than replacement — but no major source publishes prices, so insist on a written warranty and the pack’s test results.
Does a dead hybrid battery scrap the car?
Run the 50–60% maths: a £2,000 pack on a £6,000 Prius passes easily; the same pack on a £2,500 car does not. Factor in the £347-average repair route before deciding — many “dead” packs are single-module faults.
My Toyota is 12 years old — am I really still covered?
Possibly: Toyota’s battery cover extends a year/10,000 miles at each annual service, renewable to the car’s 15th anniversary (as described by DrivingElectric). It depends on an unbroken service record — check with a Toyota dealer before paying for a pack.
