You don’t say how much, if any, information you already have, or how old you or your siblings are. You have to be over the age of 18 before any agencies like social services will do anything to help you.
If you have any information about the adoption agency that arranged your own adoption you could contact them; they may be same agency that was used for your brother and sister and so they may have some valuable information that will help.
If your brother and sister are over the age of 21, then social services will not have any up-to-date information regarding where they might be, but they should be able to tell you the last piece of information that they have.
You can also apply to the UK birth adoption register so that you can be listed as wanting contact with them if they make inquiries about you. You may find that they have already registered for when you are looking for them. You can stipulate who you want contact from so you can make certain that your birth mother will not be able to know anything about you, just your brother and sister.
If you do decide to register, you will find that you will have to have an interview with a social worker who will try and prepare you for what to expect; not just the procedure but the emotional roller coaster you might be about to embark on.
Do you know anything about your other siblings? If they are adults, they may be able to give you some information without involving your birth mother at all.
