Retirees have the same consumer rights as other adults in the UK. Under the Consumer Rights Act 2015, goods should be satisfactory quality, fit for purpose and as described, while services should be provided with reasonable care and skill. Online, phone and doorstep purchases often have a 14-day cancellation period, although exceptions apply. If something goes wrong, keep receipts and contact the seller; Citizens Advice or the relevant gov.uk guidance can explain your options, and a solicitor may help with more complicated disputes.
