Mortgage Fixed Rates

My fixed rate mortgage has come to an end. Should I get a new one now or hope interest rates fall again?
This is a question for those in the UK.
My fixed rate mortgage has come to an end. Do you think interest rates will continue to fall, or is it more likely that they’ll begin to rise? Should I get another fixed rate mortgage now or stay where I am on the provider’s variable rate (slightly higher than what they’ve offered as a fixed rate) and hope interest rates continue to fall?
Thanks!
Run, not walk, to your bank and get a 15 year fixed rate loan. With all the stimulus borrowing (UK,EU,US) crowding out cosumer loan demand, it will be a very long time before you see anything near 5% fixed.
