My current CV is like this, I've uploaded it to job sites such as Monster. Someone helped me out with it and recommended I remove address and list full details of the modules I did in University, it's took up quite a bit of space, my CV is just onto 3 pages.

I'd hope my recent work experience in London would help me with getting jobs.
Is my CV bad?
Your content is good, but your layout isn't. 3 pages is a big no, as a general rule of thumb for someone with only a small amount of work experience and a degree, one page should do. Two page CVs can work, but you need to fill everything with relevant content, your current format has a LOT of unused space.
Try re-wording it into a more concise format. Talk about what skills you gained in your modules rather than a description of them, put more emphasis onto your dissertation, what was the outcome of your research?
In your work experience you are using the wrong tense, for example it should be volunteered, provided and monitored instead of volunteer, provide, and monitor.
You could also move your content around a bit more, take out some of what is said in your degree section and transfer it into the skills section.
Finally, your formatting is a bit inconsistent, you use a mixture of bullet points and paragraphs. The simplest format is using one or the other, if you want to use a mix, then you should be consistent in how you mix the two. e.g. title, paragraph, bullet point, title paragraph, bullet points. Rather than title, paragraph, title, paragraph, title, bullet points.
Hope this helps!
