Average MOT Repair Cost UK 2026
When a car fails its MOT, the repair is almost always the bigger cost. BookMyGarage invoice data for 2025 puts the average failed-MOT bill at £332 for a 3-5 year car and £425 for a 6-8 year car, both including the £54.85 test fee. That is up to 70% higher than 2022.
What is the average MOT repair cost?
There is no official average, but the largest recent sample comes from BookMyGarage, which analysed thousands of partner-garage invoices over 2022-2025. It found the average bill for a failed MOT is £332 for a car aged 3-5 years and £425 for a car aged 6-8 years. Both totals include the £54.85 statutory test fee, so the repair work alone averages roughly £277 and £370 respectively. You only pay this if the car fails: around 27.24% of cars fail their initial test, and the rate climbs with age. The cheapest failures (lights, wiper blades) cost £5-20; the most expensive (structural corrosion, emissions) can run past £1,000.

MOT Repair Costs Are Rising Fast
The test fee has been frozen at £54.85 since 2010, but repair costs have not. BookMyGarage's invoice data shows the cost of fixing a failed MOT climbing sharply across both chain and independent garages.
| Garage setting | Average invoice | Period | Change |
|---|---|---|---|
| Nationwide garage chain | £227 | 2025 average MOT invoice | +70% since 2022 |
| Smaller regional garage network | £183 | 2025 (up from £122 in 2023) | +50% since 2023 |
Source: BookMyGarage, reported by Motoring Research, 4 June 2026. Regional networks tend to focus on older vehicles, which need more work, partly explaining the steep climb.
Typical Repair Cost by Failure Type
The size of the bill depends entirely on what failed. The DVSA records every defect by category; the table below pairs each category's share of all recorded defects with the typical cost to put it right. A single failed bulb and a corroded subframe are both "MOT failures" but sit at opposite ends of the cost scale.
| Failure category | Share of defects | Typical repair |
|---|---|---|
| Lighting and signalling | 24.81% | £5-80 |
| Suspension | 19.94% | £100-500 |
| Brakes | 15.28% | £80-350 |
| Tyres | 12.94% | £50-120 per tyre |
| Driver's view of the road | 8.54% | £10-350 |
| Body, structure, and general items | 6.19% | £50-1,000+ |
| Exhaust, fuel, and emissions | 5.82% | £80-600 |
| Steering | 3.40% | £100-400 |
| Seat belts and supplementary restraints | 1.66% | £20-200 |
| Wheels and wheel bearings | 0.79% | £50-200 |
The Cost You Should Actually Budget For
The headline repair averages only apply to cars that fail. To budget sensibly, weight the repair bill by the chance your car fails at its age. That is the core of the true MOT cost: test fee plus failure probability times repair bill, not the £35 most people quote.
| Car age | Initial fail rate | What it means for your budget |
|---|---|---|
| 3 years | 14% | Low odds of a fail; a small repair buffer covers most years. |
| 5 years | 19% | Roughly 1 in 4 fail; budget the £150-300 repair buffer. |
| 8 years | 28% | Roughly 1 in 4 fail; budget the £150-300 repair buffer. |
| 12 years | 34% | Over 1 in 3 fail and bills run higher; budget £400 or more. |
| 15 years | 35% | Over 1 in 3 fail and bills run higher; budget £400 or more. |

How to Cut a Failed-MOT Repair Bill
Do the cheap pre-checks yourself. Lights, wiper blades, washer fluid, tyre tread and number-plate condition account for a large share of failures and cost almost nothing to fix before the test. The pre-MOT checklist walks through the 20-minute version.
Get the repair quoted before you agree. You are not obliged to have the test garage do the work. Take the failure sheet, get a second quote, and use the free or reduced partial-retest window. See MOT retest cost for the exact rules.
Separate dangerous from advisory. Only "major" and "dangerous" defects fail the test. "Advisory" items can wait, so do not let a garage bundle them into the must-fix bill. The advisory items page explains the categories.
Average MOT Repair Cost: Frequently Asked Questions
What is the average MOT repair cost in 2026?
There is no single official average, but the largest recent sample comes from BookMyGarage, which analysed thousands of partner-garage invoices over 2022-2025 (reported June 2026). It put the average failed-MOT bill at £332 for a car aged 3-5 years and £425 for a car aged 6-8 years. Both figures include the £54.85 test fee, so the repair element alone is roughly £277 and £370. That is up to 70% higher than 2022.
Does the £332 or £425 figure include the MOT test fee?
Yes. BookMyGarage's £332 (3-5 year cars) and £425 (6-8 year cars) averages both include the £54.85 statutory test fee. Subtract it and the repair work alone averages about £277 and £370 respectively for those age brackets.
Why have MOT repair costs risen so much?
BookMyGarage data shows one nationwide chain's average MOT invoice rose 70% between 2022 and 2025 (to £227), and a regional network's typical bill for an MOT needing extra work jumped 50% from £122 in 2023 to £183 in 2025. Parts inflation, higher labour rates and an ageing UK car fleet (older cars fail more and need more work) are the main drivers.
What is the most common MOT repair?
Lighting and signalling is the single largest defect category, at 24.81% of all recorded defects in the latest DVSA quarter. It is also one of the cheapest to fix, typically £5-80, and is often a do-it-yourself bulb swap. Suspension (19.94%) and brakes (15.28%) are the next most common and cost considerably more.
How much should I budget for a possible MOT repair?
Around 27.24% of cars fail their initial MOT, and the failure rate rises steeply with age. A sensible planning figure is the test fee plus a £150-300 repair buffer for a typical car, rising to £400 or more for cars over six years old where BookMyGarage's data shows the real bills landing. You only pay the repair cost if the car actually fails.
Do I have to use the garage that did the MOT for repairs?
No. You can take the car elsewhere for the repair work and bring it back for a free or reduced-fee partial retest. If you leave it at the test centre and it is retested within 10 working days, the partial retest is free; if you take it away and return it before the end of the next working day, the partial retest is free for a DVSA-listed set of items. Shopping the repair around can save a large share of the bill.
