you lose weight by eating less. (obviously exercise helps but the human body is incredibly efficient - it can happily run 5km on a bag of crisps and can of coke, so you need to start with diet.
go to myfitnesspal.com, sign up, fill in your stuff set it to lose 1 lb per week. download the app for your phone log everything, i mean when you eat packaged food scan its barcode, when you eat "homemade" food scan and weigh it. Seems a hardship but you very quickly get used to it and can quickly tick things off. especially log days when you fail - ie big drinking days because its important to know. that website by now must have saved lives.
fitness wise couch to 5k is a good place to start as are a few "beachbody" courses if you prefer to do some jumping around in the house or garage
edit -
some people will disagree but I got a fitbit aria scale and weigh in EVERY morning. I find it a good motivational tool as weekly weigh ins sort of let you realx a couple of days after then "diet" the couple of days before, and I hate "dietting" I prefer to just "eat better" throughout. Plus it lets you produce nice graphs like:

Thanks for that mate. I've got an apple watch so could probably do with seeing what functionality that has similar to a fitbit. Plenty for me to get stuck into there, appreciate your swift response!
