When something goes wrong, half the battle is knowing who can actually help.
This is a plain guide to the main independent bodies, regulators and charities that support consumers across the UK — what each one does, and when to turn to it. Most offer free help, and none should ever charge you to make a complaint.

Advice and support

For free, confidential help with almost any problem, start with Citizens Advice. For money and pensions guidance, see MoneyHelper; for housing, Shelter.

Regulators and ombudsmen

If a company won’t put things right, an ombudsman can rule on your complaint for free — the Financial Ombudsman Service for money, and the sector regulators Ofgem (energy), Ofwat and the Consumer Council for Water. To take a claim to court, see HM Courts & Tribunals Service, and to report fraud, Action Fraud.
