How can I find out if a block is being used on any published page?

I have an episerver project that has lots of blocks over time some of these blocks are no longer needed, is there a way to see if a created block is being used on any pages in my episerver project?

Potentially want to remove block types that will no longer be used from the code, but I'm not sure if it may break something down the line.

You can use the IContentRepository for that

This should give you a list of contents where the block is being referenced.

var contents = new List<ContentData>();
var repository = ServiceLocator.Current.GetInstance<IContentRepository>();
IEnumerable references = repository.GetReferencesToContent(contentLink, false);
foreach (ReferenceInformation reference in references)
{
    ContentReference ownerContentLink = reference.OwnerID;
    CultureInfo ownerLanguage = reference.OwnerLanguage;
    ILanguageSelector selector = new LanguageSelector(ownerLanguage.Name);
    var content = repository.Get<ContentData>(ownerContentLink, selector);

    var contentArea = content["ResponsibleEditors"] as ContentArea;
    if (contentArea != null)
    {
        if (contentArea.ContentFragments.Any(fragment => fragment.ContentLink == contentLink))
            contents.Add(content);
    }
}

Can you elaborate on why Service Locator should not be used please?

I should be more precise here - please don't use ServiceLocator "directly". Of course at the end there should be somebody that is responsible for resolving dependencies and instantiating services, but direct usage in your code is anti-pattern. I'll not try to explain, as Mark did it much better - https://blog.ploeh.dk/2010/02/03/ServiceLocatorisanAnti-Pattern/
