Ladies Regatta Coat Size 20 Zipper needs repaired/replaced (Slough central SL1)

I have a laides Regatta winter coat, Size 20, with a fur lined hood that I purchased new and had for a year before the zipper broke. I'm not good with these things, so I'm hoping someone would want to try to repair or replace the zipper - it's in perfect condition otherwise, and I hate to just throw it out.
