What should a UK garage charge for an MOT in 2026?

You do not get to choose. The maximum you may charge for an MOT on a class 4 car is £54.85, it is set in law, and going over it puts your authorisation at risk. The only decision you have is how far below the cap to drop, and for most workshops the honest answer is: do not. This applies to England, Scotland and Wales. Northern Ireland runs a separate system through DVA test centres, with its own fees.

The MOT fee is capped by law, and the cap has not moved since 2010

Most drivers assume garages set MOT prices the way they set a labour rate. They do not. Every amount on the current GOV.UK fee table is identical to the amount substituted by The Motor Vehicles (Tests) (Amendment) Regulations 2010, in force from 6 April 2010. The class 4 cap has been frozen for 16 years, and that is checkable in thirty seconds rather than trade folklore.

Put £54.85 through the ONS consumer price index (series D7BT: April 2010 = 89.2, July 2026 = 142.9) and the 2010 fee is worth £87.87 today. The cap has lost 37.6 percent of its real value while wages, rent and calibration costs went the other way.

There is no VAT on the test fee. One trap: subcontract a test out, re-charge the customer more than the fee you were actually charged, and DVSA's guide warns VAT may be due on some or all of that uplift.

The 2026 statutory maximum fees, by class

Checked against the live GOV.UK table on 27 August 2026:

• Class 4 cars up to 8 passenger seats: £54.85, and the same for motor caravans, quads, dual purpose vehicles, taxis, private hire up to 8 seats and goods vehicles up to 3,000kg
• Class 7 vans, 3,000kg to 3,500kg: £58.60. Zero-emission goods vehicles from 3,501kg to 4,250kg are a separate band at the same fee goods vehicles up to 4,250kg
• Motorcycles, class 1 and 2: £29.65 solo, £37.80 with a sidecar

What an MOT actually costs you to perform

ONS Annual Survey of Hours and Earnings 2025 puts median gross full-time pay for a vehicle technician at £37,458. Add employer NI at 15 percent above the £5,000 secondary threshold (£4,869) and the 3 percent pension minimum (£937), and one median tester costs £43,263 a year before the Employment Allowance, which most independents can claim against the NI. Spread over roughly 1,740 attended hours after holiday and training, that is about £24.86 an hour in wage cost alone, before the bay it stands in.

Our hourly rate arithmetic works out the minimum viable bay-hour for a two-bay independent outside London at £57 at zero margin, covering wages, rent, rates, insurance, tooling, software and an owner's wage. That is the floor, not a target. Add the £2.05 DVSA slot fee and a test costs:

• 45-minute test: costs £37.69, so the cap leaves £17.16
• 60-minute test: costs £59.05, which is £4.20 more than the cap
• 45-minute test: costs £44.80, so the cap leaves £10.05
• 30-minute test: costs £30.55, so the cap leaves £24.30

There is no statutory minimum test time: 45 to 60 minutes is trade convention, not a DVSA figure.

Those costs are our own estimates, not published statistics, and your rent will move them. The shape holds anyway: at the legal maximum, with no discount at all, an hour-long MOT earns about a fiver, and the law forbids you charging more.

The DVSA slot fee is charged per pass, not per test

Slots cost £2.05 each, VAT free, bought in advance, and one is consumed when a pass is recorded. A fail does not consume one, though you must hold an available slot for any test or retest to be registered.

When is an MOT retest free?

Section L2 of the DVSA MOT testing guide sets the rules, and this is where the trade most often gets it wrong at the desk:

• Free, rule one. The vehicle stays at your VTS after failing, never leaves, and is retested before the end of the tenth working day following the test.
• Free, rule two. It returns to the same VTS before the end of the next working day on which testing is carried out, and failed only on listed items: lamps excluding headlamp aim, mirrors, seats, seat belts but not anchorages, plates, horn, VIN, glass, wipers and washers, filler cap, doors, bonnet, boot lid, wiring, towbars, TPMS, sharp edges, steering wheel, plus tyres and wheels except on classes 1 and 2.
• Partial retest. Taken away for repair and back at the same VTS inside those ten working days: charge up to half the statutory maximum, which is £27.42 on a class 4 car. One partial re-examination per full test, then it is a full test at the full fee.
• Pass after Rectification at Station. Fix a minor defect there and then, re-examine under PRS, and no further test fee can be charged. You can still charge for the repair.

A change of VTS ownership between test and retest voids every concession. You may charge under the statutory fee, but never let a card surcharge push the total over the cap.

The discount arithmetic, and why it does not work

Take the 60-minute test at £59.05 fully loaded. Every pound off the £54.85 must be earned back in repair work:

Required conversion = shortfall per test ÷ average gross profit per converted repair job.

Using £120 average gross profit per repair job, which is our estimate and not a sourced figure, against DVSA's initial fail rate for classes 3 and 4 of 27.24 percent in the quarter April to June 2025, or 28.08 percent across the whole of 2024 to 2025:

MOT price	Shortfall	Conversion needed	Share of the cars you fail
£54.85	none, £5.27 profit	none	none
£39.99	£9.59	8.0%	29%
£29.99	£19.59	16.3%	60%
£25.00	£24.58	20.5%	75%
£19.99	£29.59	24.7%	91%

Read the right-hand column again. At £25 you need three quarters of every car you fail to become paid repair work at your shop just to reach zero. At £19.99 you need 91 percent, which does not happen. Put your own job value into the formula before you print a price board.

You cannot claw it back by testing faster either. DVSA records the duration of every test, benchmarks each tester against site and national averages, and tells managers to filter for short passing tests and investigate them. Speed is not a lever here. It is a compliance risk with your authorisation attached.

Why the cheapest MOT brings you the worst customer

This is reasoning, not data, but the mechanism is simple. The 27.24 percent fail rate is a ceiling on conversion, not an expectation, and 5.21 percent of class 3 and 4 tests already resolve as pass after rectification, where a further test fee is forbidden. Then consider who drove past three garages to save £30. That is a customer selecting on price, at exactly the moment you need a yes on a £280 suspension job. Most take the VT30 and shop it.

The work itself is worth having. DVSA records 2.42 defects per initial failure: lamps and electrical on 10.36 percent of all tests, suspension 8.65 percent, tyres 6.23 percent, brakes 6.10 percent, and tyres alone account for 60.32 percent of all dangerous defects. That is not work to rush for someone who was never going to authorise it.

Is the cap going to rise?

It has not moved since 2010. The Department for Transport's own consultation noted that consumer prices rose around 34 percent between 2010 and 2022, and that the maximum would sit near £73.50 had it merely kept pace with inflation. The Independent Garage Association has publicly called for £95.

Nothing has been confirmed, so price the workshop you have rather than the cap you would like. If it does rise, every garage that has trained its customers to expect £25 will find that the increase belongs to somebody else.

What to do instead of discounting

With 23,097 private MOT stations in Great Britain, you will never be the cheapest for long. Compete on what a price board cannot copy.

1. Sell the slot, not the price. Same-day and while-you-wait beats £10 off for anyone with a job.
2. Bundle rather than discount. A test at the cap alongside a service beats a £25 MOT alone. See what a service should cost.
3. Record advisories properly. Photographs, dates and a written quote turn a fail into authorised work, so a vehicle health check is worth more than a discount.
4. Own the reminder. MOT reminders are the cheapest repeat work in the trade. Not a station yet? Start with how to become one.

The bottom line

An MOT is a legally capped, VAT-free, near break-even hour of bay time that hands you a queue of cars needing work. Charge £54.85 and make the money on the defects you find, quoted properly with photographs, to a customer who chose you for something other than price.
