Recommendations for an affordable smart waterproof jacket for work

[LiquoriceAllsorts2]

I am looking for a not too expensive smart waterproof jacket (long enough to cover longish blazers) that I can wear for work.

I have casual jackets and smart winter coats but looking for something imbetween

I have a waterproof Mac with a hood from Zara. It’s handy as looks smart but equally can be dressed down with jeans and trainers too.
