Looking for swifty special needs pushchair - where can I buy one in the UK

I think most people get them from wheelchair services, have you checked you can't get one for your child through them? If they won't give your child what you think is best some areas give a voucher to part fund a privately bought chair. But watch out they won't service/repair it if bought via vouchers and you only get one every few years so if not suitable you are a bit stuck. 

There are sometimes second hand special needs trolleys on EBay, and there are several buy/sell/swap groups on Facebook and I have seen a few swifty's recently. Special needs pushchairs and special needs buy/sell/swap are good groups 

new life is a charity that helps sometimes with funding.
