MOT history check by registration

A single pass tells you almost nothing. The value is in the sequence, and there are three columns worth reading properly: the result, the advisories, and the mileage at each test.

Results. One fail followed by a same-week pass is normal — a bulb, a wiper blade, a tyre replaced on the spot. What matters is a repeated fail on the same system across different years, especially corrosion, suspension or brakes, because that pattern usually means the cheapest possible repair was done each time.

Advisories. These are the examiner's warnings about parts wearing out that were still legal on the day. An advisory that appears three years running and then becomes a fail is the clearest possible sign of deferred maintenance. Advisories about underbody corrosion on an older car deserve particular attention, because it rarely gets better.

Mileage. Every test records the odometer reading, which makes the history the best free way to sanity-check a used car. Look for an implausible jump, a drop, or a car whose annual mileage collapses from 15,000 to 2,000 without explanation. Genuine changes in use happen; a seller unable to explain one is a problem.

Cars need their first MOT three years after registration, then annually. You can test up to a month minus a day before expiry and keep the same anniversary date — test earlier than that and the renewal date moves to the new test, quietly costing you part of a year over time.

Driving without a valid MOT risks a fine of up to £1,000, and most insurers treat a lapsed MOT as grounds to challenge a claim. The two legal exceptions are driving to a pre-booked test and driving to a garage for repairs. A car can also be taxed only if it has a valid MOT, so an expired test eventually blocks renewal too.

Some vehicles are exempt: most cars over 40 years old with no substantial changes, and fully electric goods vehicles under specific conditions. Exempt is not the same as unroadworthy-proof — the roadworthiness requirement applies regardless of whether a test is due.

Cleanliness is not a test item, and no valet turns a fail into a pass. There is one practical exception worth knowing: a test can be refused if the vehicle is too dirty or too full for the examiner to work on it safely — obscured lights and plates, or a boot and footwells packed with belongings blocking access. Emptying the car and clearing the glass and plates removes that risk entirely.

The stronger case for cleaning is a sale. A clean cabin and clean paint photograph better on a listing and give a buyer less to negotiate against. We are not going to attach a figure to that — we do not have data we can stand behind, and we will not invent one.

What we can state plainly: Valetly sends a vetted, insured valet to the address where your car is already parked, anywhere in Greater London and the M25 belt. Prices are fixed and published, from £75 for the shortest exterior appointment to £269 for the longest inside-and-out one, banded by vehicle size, with no call-out fee. Every valet is identity-checked and carries at least £1m public liability insurance, every job is documented with before-and-after photos, and Valetly is registered in England and Wales under company number 17255496.
