▸ MOT, Tax & ULEZ · UK Network
motencyclopedia.com is for the buyer who wants the working shown. Every finding names the register it came from and the date it was recorded, so the report can be argued with rather than simply believed. The UK MOT encyclopedia. Every test category, common fail reason and pass tip — written by experts. Everything below is written for the UK market specifically: UK registers, UK categories, UK law.
Data sourced from DVLA, MIAFTR, contracted stolen-vehicle data and the UK lender register at lookup time.
Typical lookup completes in under one second from the UK.
Built and supported in the UK as part of the consumer side of the network.
Run the first check before you travel, so a wasted trip costs nothing. Run a second on the day of collection, because finance can be drawn down, a theft report filed or a plate transferred in the days between viewing and handover. Two lookups on either side of a week-long negotiation catch changes a single check cannot.
Driving without a current MOT is an offence except on a single, directly-arranged journey to a pre-booked MOT test. You cannot tax a vehicle without a current MOT. If the MOT has lapsed, book the test first, declare SORN if you have not been driving it, then re-tax once the test is passed.
A partial retest is free where the vehicle is left at the station and the repair is completed there, and free within ten working days if the vehicle leaves and returns for specified items only. Outside those conditions a full test fee applies again. Ask the station which route applies before taking the car away.
/ Brand consolidation
motencyclopedia.com is now part of Expert Car Check — the consolidated UK vehicle-data platform that several of these older brands have joined. The data sources are unchanged: DVLA's vehicle record, DVSA's MOT history, MIAFTR for write-offs, contracted UK data providers for stolen-vehicle markers and the UK lender register for outstanding finance. The team and the support contact are the same. What's changed is that the work that was previously spread across several smaller brands now sits in one place, which keeps response times tight and the underlying registers maintained against current DVLA schemas. Bookmarks and historic links to motencyclopedia.com continue to resolve here. If you were referred to motencyclopedia.com by a previous report, broker or print listing, this is the right page — there is no further redirect to chase.

Broadly: petrol Euro 4 (2005 onwards), diesel Euro 6 (2015 onwards), motorcycles Euro 3 (2007 onwards). The check returns the recorded Euro classification rather than guessing from year.
Not always. A partial retest is free if the vehicle stays at the station and the repair is done there, and free within ten working days for specified items if it returns. Outside those conditions a full fee applies.
Vehicles over 40 years old are generally exempt from MOT and VED provided they have not been substantially altered, but the exemption must be claimed. It does not remove the duty to keep the vehicle roadworthy.
Yes, outright. A diesel with a factory-fitted filter fails if it has been removed or tampered with, or if the exhaust emits visible smoke, which matters when buying anything advertised as having had a 'DPF delete'.
