DVLA, DVSA, two government agencies, four letters each, one letter different. It is no wonder UK drivers mix them up. But the distinction matters: contact the wrong one and you will be politely redirected, having lost a morning.
Both are executive agencies of the Department for Transport, and both deal with cars and drivers, but they handle completely different sides of motoring life. One does paperwork; the other does standards and testing. Search for one and you will often land on the other’s page. Here is exactly which is which, so you never waste a morning on the wrong one.
What the DVLA does
The Driver and Vehicle Licensing Agency is based in Swansea, Wales, and it is the agency most drivers deal with most often. Its job is licensing and records, the administrative backbone of UK motoring:
- Driving licences, issuing new licences, renewals and replacements, and recording endorsements and penalty points.
- Vehicle registration, registering new vehicles and issuing V5C logbooks, the document that names the registered keeper.
- Vehicle Excise Duty, collecting road tax, including SORN declarations for vehicles kept off the road.
- Keeper records, maintaining the database of who is responsible for every vehicle on UK roads.
- Personalised registrations, selling and transferring private number plates.
- Medical fitness to drive, assessing whether drivers with certain medical conditions can keep their licences.
Short version: if it involves a licence, a logbook, tax, or a number plate, it is the DVLA. If you want to estimate the tax before you deal with them, try our free road tax calculator.
What the DVSA does
The Driver and Vehicle Standards Agency is based in Bristol and was formed in April 2014 from the merger of the Driving Standards Agency (DSA) and the Vehicle and Operator Services Agency (VOSA). Its job is standards, testing and enforcement, making sure drivers are competent and vehicles are safe:
- Driving tests, running theory and practical tests for cars, motorcycles, lorries and buses.
- Driving instructors, approving and regulating approved driving instructors (ADIs).
- MOT standards, writing the inspection manual testers follow, approving MOT test stations and testers, and quality-checking their work.
- Roadside enforcement, stopping and checking vehicles, particularly lorries and buses, for roadworthiness and compliance.
- Vehicle recalls, monitoring safety recalls. You can check whether a vehicle has an outstanding recall on GOV.UK.
Short version: if it involves a test, of a driver or of a vehicle, or a complaint about testing standards, it is the DVSA.

Which one holds your car’s data?
This is where the confusion really bites, because the answer is both, but different data.
The DVLA holds the car’s identity and legal status: registration mark, make and model, fuel type, date of first registration, tax status, and the registered keeper’s details. When you check whether a car is taxed, you are asking a DVLA question.
The DVSA holds the car’s test history: every MOT result on record, with pass and fail outcomes, the mileage recorded at each test, and the defects and advisories the tester found. When you look up a car’s MOT history on GOV.UK, or through our free MOT history checker, you are reading DVSA data.
Used together, they tell the full story. The DVLA data confirms what the car is and whether it is legally on the road; the DVSA data shows what condition it was in every time it was inspected. You can see the official MOT record free at gov.uk/check-mot-history. A car can be perfectly taxed and registered yet carry a string of worrying MOT advisories, or have a clean MOT record and no current tax. Check both before you buy.
One important boundary: neither agency’s full database is public. Keeper names and addresses, and driver licence details, are not freely available through public vehicle checks, they are shared only with parties that have a legal reason, such as the police or parking enforcement. What you can see free is the vehicle’s own record: its registration details and tax status on one side, its MOT test history on the other.
Who do you contact for what?
Quick reference for the situations drivers actually run into. When in doubt, ask yourself: is this about a document or a payment (DVLA), or about a test or a standard (DVSA)? That split resolves almost every case:
- Lost your V5C logbook, or need to update the keeper details → DVLA
- Tax the car, declare SORN, or query a tax refund → DVLA
- Renew your driving licence or change the address on it → DVLA
- Buy or transfer a private number plate → DVLA
- Book, move or cancel a driving test → DVSA
- Complain about an MOT tester or test station → DVSA
- Ask what the MOT test covers, or query a testing standard → DVSA
- Check for outstanding safety recalls → DVSA
What about Northern Ireland?
Drivers in Northern Ireland have a third acronym to learn: the DVA (Driver & Vehicle Agency). It combines most of both agencies’ roles, driving tests, MOT testing, instructor approval and licensing, for Northern Ireland. The main exception is the vehicle database itself, which the DVLA maintains for the whole of the UK, and road tax queries still go through the DVLA’s arrangements with the Department for Transport.
If you move between Northern Ireland and Great Britain, your licence and vehicle records move with you, the DVLA’s vehicle database covers the entire UK, so a car’s registration and tax record stay in one place wherever it is kept.

Swansea or Bristol? Now you know
Remember it this way: the DVLA does the paperwork, licences, logbooks and tax. The DVSA does the standards, tests, testers and enforcement. Tax question? Swansea. Test question? Bristol. And when you’re checking out a used car, read both agencies’ data: the DVLA’s for what the car is, the DVSA’s for what shape it’s in.
