Planning to get an abortion

I've just found out I am 4 weeks pregnant. Unplanned and we have decided a termination is the best for our family (we already have a daughter). My daughter has just started nursery, I've just gone back to work after 4 years, we are planning to buy a house, a new baby isn't in our plans and we are both sure we don't want another child. We just happened to get caught on a quick fumble unfortunately I have been off contraception due to abnormal cervical screening results.

I have read into in and looking at a surgical termination under conscious sedation as I need to be back on my feet fast.

Has anybody any experience with this at all? I am in the UK. Thanks!
