SEAT Leon vs Skoda Octavia: which is the better used buy?

On DVSA MOT records the SEAT Leon and the Skoda Octavia are too close to call — 1.4 percentage points apart on first-time MOT passes once you allow for the age of each fleet, which is inside what the choice of cars counted can move. A winner is named only at 2 points or more. A pass with rectification at the station counts as a pass here, and as a failure in DVSA's own initial-test measure.

MOT first-time pass rate

Counted from DVSA’s anonymised MOT test records. “vs age-matched” compares each model against what the national fleet scores at the same age — the only fair better-or-worse number, because an older fleet fails more whatever its build quality.

These figures count every generation still on the road, not only the one described below: mostly SEAT Leons registered 2007–2022 and Skoda Octavias registered 2005–2022.

Source: DVSA MOT Anonymised Data 2025 (Open Government Licence v3.0). National first-time pass rate 77.3%. Class 4 tests in Great Britain, test type NT (a normal annual test), retests excluded. A pass, or a pass with rectification at the station, counts as a first-time pass; DVSA's own initial-test measure counts a rectified pass as a failure and so reports a lower figure. Testing in Northern Ireland is run separately by the DVA under its own rules. The difference is worked out before rounding, so it can be 0.1 away from the two rounded figures beside it.

SEAT Leon

Mk3 2012–2020, Mk4 2020+ · compact family hatchback / estate

The SEAT Leon is one of the UK's best-value compact hatches, sharing its MQB platform with the VW Golf. The Mk3 (2012–2020) is strong overall, but owners report DSG mechatronic faults and oil consumption on early TSI engines. The Mk4 (2020+) has better infotainment. Best buy: 2021+ Mk4 1.5 eTSI mild hybrid. Worst: no single year stands out on DVSA MOT results.

Check: Check the service history for the cambelt inspection or change at the interval SEAT's schedule sets for the engine code. No record on a high-mileage or older car means budgeting for it now.

Check: Confirm which gearbox the car has from its engine, then test in slow traffic and from cold. The wet-clutch DQ250 has a scheduled gearbox oil change, so look for it in the history; the dry-clutch DQ200 has none. A fluid change (£200–£300) often helps early-stage judder.

A car registered from April 2017 with a list price over £40,000 when new adds the £440/year Expensive Car Supplement in years 2–6 (£640 in all). Cars registered 2001–2017 pay a CO2 band, roughly £20–£790/year (2026/27 rates).

Skoda Octavia

Mk4, 2020+ · compact family hatch and estate (saloon-shaped hatch)

The Mk4 Skoda Octavia (2020+) shares the VW Golf Mk8 platform — including its early infotainment software bugs (resolved in 2023+ updates). The e-TEC 48V mild-hybrid starter generator has occasional faults, and the DSG differs by engine: dry-clutch DQ200 on e-TEC petrols, wet-clutch on 2.0 TDI and vRS. Best-buy: 2023+. Worst: 2020–2022 infotainment.

What goes wrong

Safety recall R/2024/017recall
On certain vehicles with electromechanical brake servo and DSG (Direct Shift Gearbox) of a limited production period there is a possibility that a heat protection mat was incorrectly fitted.

Check: Confirm which gearbox the car has from its engine. On a wet-clutch car, the service history should show the scheduled DSG oil change; on an e-TEC car with the DQ200 there is no scheduled gearbox oil service, so do not expect one. Pull away uphill from a standstill to provoke any judder.

Which one suits you

SEAT Leon

Good for: Buyers wanting Golf-level engineering at a lower price. Family buyers who need the Leon ST (estate) for boot space. Performance fans who want the CUPRA Leon. Buyers doing mixed town/motorway commutes.

Less good for: Buyers who want the simplest possible ownership — the Golf has better dealer network depth in the UK. Mk3 DSG buyers doing city-only miles with no gearbox history. Buyers of an older TSI with no record of a cambelt inspection or change.

Skoda Octavia

Good for: Practical family buyers wanting Golf substance with Skoda value — bigger boot, lower price.

Less good for: Buyers without tolerance for early Mk4 infotainment quirks.

Frequently Asked Questions

Which is more reliable, the SEAT Leon or the Skoda Octavia?

Neither stands out on the MOT measure. Their first-time MOT pass rates sit 1.4 percentage points apart once each is compared against the national rate for cars of the same age, which is too close to call (we name a winner only at 2 points or more). A pass with rectification at the station counts as a pass here, and as a failure in DVSA's own initial-test measure. The MOT checks safety and emissions items, not the engine, clutch or gearbox, so this is one measure of how each car holds up rather than a full reliability verdict. Pick on the specific faults each is prone to instead.

How do the MOT pass rates of the SEAT Leon and the Skoda Octavia compare?

80.1% of SEAT Leons pass their MOT first time (19,349 tests in DVSA's records) and 80.5% of Skoda Octavias pass their MOT first time (20,737 tests). The national first-time rate is 77.3%, but cars of the SEAT Leon's age average 79.1% and cars of the Skoda Octavia's age 78.1% — so the SEAT Leon runs 1.0 points better than its age group and the Skoda Octavia runs 2.4 points better than its own. A pass with rectification at the station counts as a pass here, and as a failure in DVSA's own initial-test measure.

Which years of the SEAT Leon and Skoda Octavia should I avoid?

SEAT Leon: Early Mk3 (2013–2014) cars are the oldest and highest-mileage Leons on sale, and their automatics carry the most owner reports of DSG judder. The 1.4 TSI has a toothed timing belt, not a chain, so check when it was last inspected or changed. The DVSA MOT table on this page rates 2013 and 2014 registrations above all cars registered those years, so they are not named as years to avoid. Judge a Leon by its registration, service history and the checks below rather than by year. Skoda Octavia: Pre-2023 Mk4 inherited the Mk8 Golf's infotainment issues directly. Cars built 4 May 2020 to 14 November 2023 are also inside DVSA recall R/2024/017: on Octavias with the electromechanical brake servo and DSG a heat-protection mat may have been fitted wrongly, so the brake-fluid reservoir can melt and leak (15,729 vehicles across Octavia and Superb). Check the registration.

Is the SEAT Leon or the Skoda Octavia cheaper to run?

On fuel the SEAT Leon has the edge: its most economical version returns up to 63 mpg, against up to 57 mpg for the Skoda Octavia, on the figures in our model guides. For cars registered from April 2017, vehicle tax works the same way for both: the £200/year standard rate from the second year, hybrids included, plus the £440/year Expensive Car Supplement in years 2–6 on a car that listed at over £40,000 new — the price when new, not what you pay for it used. Any SEAT Leon or Skoda Octavia registered between 1 March 2001 and 31 March 2017 pays a CO2 band instead, roughly £20–£790/year (2026/27 rates). Insurance differs mainly by driver and postcode rather than by model, so treat any model-level insurance figure with caution.

MOT figures are counted from DVSA records and are the only measured statistic here. Prices, economy and tax bands are indicative and vary by specification, condition and where the car has lived. Last reviewed: 2026-10-06 / 2026-10-06.
