Following the completion of works the office in Scarborough Street is open to people five days a week.
Jill said: “Myself and my team have been dealing with casework and other enquiries since the day after the by-election, but it has taken a little while till we have been able to get the constituency office open.
"The surgeries by appointment will continue to take place at the Civic Centre as was the custom of some of my predecessors."
