We aim to give you a great experience. If something goes wrong, we want to put it right quickly and fairly.

What happens next
- We acknowledge your complaint within 3 working days.
- We investigate and aim to give a full response within 14 working days. If we need longer, we will tell you why and when to expect a reply.
- We will explain our findings and any action or refund we offer.
If you are still unhappy
For data-protection complaints you can contact the Information Commissioner’s Office at ico.org.uk. For consumer disputes you may also contact Citizens Advice or your local Trading Standards.
SackCheck is a self-help service, not a regulated legal provider, so complaints about legal advice fall outside the Legal Ombudsman’s remit. If you used a solicitor we referred you to, complaints about that solicitor go to them and ultimately the Legal Ombudsman.
