Of that I am sure that I don’t need to. I have british counterpart and my license is from EC country, so I don’t need until I will pass my test (that can be useful information for you too in case if you will have some learners from another EC countries, as there is a myth that you MUST exchange, when it’s not true (unless you are over 45, which is not my case)).

Visitors
If you hold a valid community licence and are visiting GB, you can drive any vehicle if your licence is valid. The appropriate full entitlement for the vehicle you wish to drive must be shown on your licence.
Residents
If you have a valid community licence, this will authorise you to drive in GB for the period set out below. Alternatively, you can exchange your licence for a British one at any time.
Provided your licence remains valid you may drive in GB:
Car, motorcycle driving licence holders (ordinary driving licence):
until aged 70 or for three years after becoming resident, whichever is the longer period
Lorry, minibus, bus driving licence holders (vocational driving licence):
until aged 45 or for five years after becoming resident, whichever is the longer period
if you are aged over 45 (but under 65) until your 66th birthday or for five years after becoming resident, whichever is the shorter period
if you are aged 65 or over for 12 months after becoming resident
In order to continue driving after these periods, you must get a British driving licence.
Register of community licence holders
Holders of community licences with vocational entitlement who live in GB must register their details with the Driver and Vehicle Licensing Agency (DVLA). For further information you can contact them on 0870 240 0009.
Drivers of small vehicles may register also, if they wish. To register, drivers should notify DVLA of their name, address and driving entitlement. Drivers who register will receive their licence back together with a UK counterpart document. This would enable them to take advantage of the fixed penalty system for road traffic offences instead of having to go to court.
