While I would never put anyone down who is trying to better themselves, I think if you want to transfer your qualifications to the UK your probably going to have a lot of work too do!
SpannersatKL is right in what he says, if you want a licensed job in the UK you need a Part-66 from one of the EASA member states. To apply for the exams you would need to be over 21 & be able to demonstrate four and a half years experience on aircraft appropriate to the category that you are applying for.
If you don't have the experience you could go for a suitably approved, either Part-147 or CAA apprenticeship course which if you were successful results in a susspended license, suspended until you have the time-on-spanners necessary to get a full license.
I would suggest that you may find it hard to get a job in the UK without a license, and it may be difficult to get an un-licensed position coming from a country outside of Europe.
Good luck in your efforts
