Can my employer make me redundant if my job still exists?

My employer has told me that I will be made redundant as the part of the business I work in would prefer to have someone who is on site full time. 

I have been in my current role 9 years, it is a head office central function role, requiring travel to various locations.  My contract states that I will travel as required to perform my role.  

My employer has now decided that to do the role effectively I must be in one location permanently, this location is 300 miles away, therefore unless I uplift my family, my job will be given to someone else and I will be forcibly made redundant. 

The role remains the same apart from this one change.

Do I have grounds for claiming unfair dismissal? 

There have been no issues with my performance and I have not been consulted in the decision process.

Any advice appreciated.
