Our rights guides help you stay informed about legislation and regulatory guidance across various sectors and issues. Advocate for yourself and get the support and assistance you’re entitled to from companies and regulators.
Get your voice heard
Our platform helps connect you to household names, ombudsmen and regulators - so you can be certain that you’re talking to the right person at the right time.
Join a collective redress
We work with recommended providers to help you find out if you've been overcharged, mis-sold, or are entitled to some form of legal redress. Our expertise in consumer rights means that we are leading the way in collective redress in the UK.
