Been using Mumsnet for ages now and helped me a bunch so excited to finally give something back lol :)
Found this offer to get £75 for opening a free Tide bank account through Reform Financial. https://reform-financial.co.uk/services/free-business-bank-account/
I got my £75 2 weeks after opening the account and now use the account for my cleaning business (it's actually way easier than my Natwest account and has more features).
I checked when I signed up and you don't need to be a business owner, you can just have an idea for a side hustle or some freelance work you want to start. I set up a sole trader account using my own name and checked this was ok with Tide.
It took me 5 mins to sign up, the account was open in minutes, and apart from slightly long response times through their app if you need to talk to anyone (still WAY quicker than high street banks), the process has been super easy!
A bunch of my friends and family have signed up too and had a similar experience so hopefully you other mumma's get something out of it too.
Enjoy!
