This reads like the author has earnestly followed some kind of How To Write a Comic Novel course. 
 1 - write about what you know. Check! She's British Ukrainian and this is all about British Ukrainian stuff. 
 2 - Decide on a strong central narrator and give them a winning personality. Check! Boy oh boy does our first person narrator want you to like her. When I was reading this today and the doorbell rang I thought that was her come round with some freshly baked pampushky. As the story rolls along she's forever nudging your ribs and smirking loudly and huff-huffing at the silly things her characters do. 
 3 - Invent a bunch of lovably eccentric types - a VERY lovably eccentric yet exasperating yet LOVABLE father is recommended, everyone likes one of those. Check! Check! Check! For instance, the narrator is a sociology lecturer but her sister keeps calling her a social worker - that's quite funny on page 37! And there it is again on page 83, 96, 114 and 289. 
 4 - But make sure your readers know that this isn't just a trivial make-fun-of-the-daft-immigrants farce by adding in some DARK FAMILY HISTORY which since this is all about Ukrainians might well be pretty dark indeed. Make em laugh, make em cry. Very important. Check! After the farcical golddigging-hussy-is-trying-to-marry-my-father story comes the what-my-dad-did-in-the-holocaust section. 
 5 - In case that bastard Paul Bryant reviews your novel on Goodreads, namecheck his home town to put him in a good mood. Check! Nottingham! Right there on page 124. I had to give this prize-winning novel a whole extra star just for that.
