That is not as easy a question to answer in a universal way as you might think. You never know which style of learning something fits another person.
For starters I am not an EE. My educational background was that of an ME. I taught myself somewhat, and knowing the basic math from my ME background made that easier. In time just to get a more thorough education for my hobby and the increasing instrumentation use in my job, I started taking electronics in a community college. I don't know if you have similar things in the UK. Those are 2 year colleges oriented more toward vocational education like nursing, welding, or HVAC repair, or electronics or such fields. I did end up with a 2 year degree in industrial electronics. The math for that is not what is needed for an EE. The math for this lower level hardly goes beyond basic algebra.
So not an EE, and sometimes that shows. It is enough knowledge to know my way around circuits you'll find in electronics.
Now long winded answer. I'm not suggesting you do what I did to learn electronics. Though if you did, I think you'd find time spent that way is actually more efficient and leaves fewer gaps than doing it all yourself.
I'd suggest looking at a few books on the subject at a real live bookstore. Get one or two that seem good to you. What I find holds people back is you really need a good grounding in the very basics of electricity. You really need a textbook approach to that before going further. Such topics are not riveting material. Most DIY books I've seen get into too many topics trying to make it interesting, but when you are done you don't have enough of the basics to have learned all that much.
Here is the table of contents of the 12th edition of a text I had. These are the basic subjects you would do well to learn. None are really very hard, but they aren't flashy topics by themselves and so many DIY books want to gloss over this. I'd look around and find an earlier edition. The subject matter hasn't changed and you can get earlier editions for a fraction of the price. 8th editions are around inexpensively. A copy of this book as a reference along with the more typical teach yourself books might be a good combination.
This is Bernard Grob's Basic Electronics.
