Short answer
A Title Register can show registered ownership information, but GOV.UK explains that some downloaded copies are for information and cannot be used as proof of ownership. If proof is required, official copies or professional advice may be needed.
Ownership information vs proof
Customers often order title documents to check who is recorded as the registered proprietor. That is different from using a document in a legal process where formal proof or certified official copies may be required.
