I wonder how background checks work. I've had an offer from an english company (the job being in France) I was willing to accept. They made an offer valid only with a background checked ok. I signed an electronical consent to a third party (no signature). I do realize they are asking private data, i would not have given a french employer. I have besides another offer from a french company. How do I do to renege and have the background chek cancelled? I don't want them to keep any of my data. Please help.

You immediately phone the English company that made the offer. You tell them that you don't want the job, and that you are officially withdrawing your consent to a background check. Then, you follow it up with an email, and request a confirming reply.
Don't wait. Once it is started, you may not be able to stop the process.
Joe Strazzere gave you the practical answer. I'm adding another, which I think is important enough not to be a comment.
A company based in the UK must abide by the Data Protection Act. This means that they must 1) tell you why they require any personal information from you (a background check is a valid reason) 2) destroy it when those actions are complete (i.e. when the check is done or cancelled) 3) not use it for any other purposes 4) keep it secure while they have it.
If you have any reason to think that isn't happening you can talk to the appropriate authorities.
