These are both great websites:
https://www.homebirth.org.uk/
https://homebirthersandhopefuls.com/
You should also look and see if there is a home birth group in your local area. Your midwife might know. I know I got a brochure about mine when I had my booking appointment. There's also a Home Birthers and Hopefuls Chat group on Facebook that's super helpful and full of lots of great ladies who have had or are planning home births.
I had my daughter at home almost a year ago (she was my first) and it was wonderful. The best decision I could have made for both of us.
I'd also really recommend looking into natal hypnotherapy. I found it helped me so much. As you've given birth before, you have a bit more of a sense of what to expect, but it's a great tool.
