If you hold a valid driving licence or International Driving Permit (and are not barred from driving in the UK) you may drive (the vehicles covered by your licence) here for 12 months from the date you arrived in the UK.
You must also be covered by car insurance for the vehicle you are driving, and the vehicle must have a valid MOT test certificate.
If you choose to drive in the UK, it is important that you understand the law. The UKCISA guidance notes on give a good overview of what you need to know.
