Amalgamation of two adjoining titles

I recently purchased an adjoining property that had, until 1974, been part of the same title as my main residence. They were both part of a country estate that was divided into 10 lots and sold off when the last owner died without heirs. Both properties share a private driveway and are not fenced off from one another. 
Is that a sufficiently good reason for an application to amalgamate the titles? They are not mortgaged or otherwise encumbered.

Richard - not in my experience no. Nothing to be gained for you or us in amalgamating them 

wouldn’t the advantage to me be that I would not be liable for 2 sets of council tax?

Richard - Council tax is not payable per registered title. But if you are going to combine the two postal addresses into a single one and the local authority then approve the new/defunct address you can apply to amalgamate the titles on that basis and your request will be considered on merit

I see, thanks for the clarification Adam
