Skipping MEng to go straight to EngD or PhD from BEng
I'm not in UK, and it isn't my field, but the only real barrier is getting accepted into a program. You may be missing some technical background without an MS, but if you are accepted there will presumably be a way for you to fill in what you need. 

Some places the rules may make it impossible for you to even apply, specifying a given degree, but otherwise, the only way to know is to make application and make it as positive as you can. Let the review committee know why you are a great candidate with a high likelihood of success. Of course that is the situation no matter what your formal background. 

If an institution doesn't have a path from where you are, it is very likely to be obvious from their online materials.
