Hi Hasin,
I must applaud you for finally deciding its time to get back into building your career, thats the first step in the right direction.
As per your question, you should just start applying for jobs and see how it goes. You do not need get your skills certified by any body in the UK - thats only for doctors, teachers, specific engineering roles - where certifying skills are a must to work in the UK
I guess you asked the question because your hubby's a doctor but luckily for us IT people, lives are not dependant on our useless coding so you can just start job hunting
Going about how you do it is the big challenge. Just go through a few posts before yours and there's some wonderful advice given by forum members
Key bits to keep in mind
1. Have an updated and appropriate CV for each role you apply for. Your CV is basically a selling tool - you are judged by what your CV says about you.
2. Be proactive, attend as many interviews as possible and brush up on your communication/technical skills
3. If salary is not important then take anything that comes along which interests you. Given you were out of the market for 7years, there's a lot to learn and pick up so might be easier to start lower down the ladder and then look out for better roles once you are confident of your skills
And finally, Dont lose heart and just keep applying and going for interviews. The more you attend, the better your chances of getting a role
All the best
