Fixing my interest rates on mortgage

Hope these kinds of posts are allowed

Have to remortgage this month and unsure what to do with regards on how long to fix for. I got lucky 3 years ago and fixed at 1.26%. My options now are

3 year fixed at 4.42% 5 year fixed at 4.26%

I’m not really in the loop on the rise and fall of interest rates so was hoping some people could offer some advice or what they would fix at

I’m looking at the 5 year fixed but I worry in 2-3 years time it could drop even lower
