How to Complain: Company Guides

Find the right complaints route, and the ombudsman if it goes wrong, for major UK companies.

Pick a company to see where to send your complaint and what to do if it is not resolved. We only list information we have checked on the company’s or scheme’s own pages. Not on the list? Use our free letter templates and the Know Your Rights guide, or ask us.

Independent service. CPUK is an independent informational service and is not affiliated with, endorsed by, or partnered with any of the companies listed below. All product names, logos, and brands are property of their respective owners.
